Cognates.
Afroasiatic languages share a vocabulary of Proto-Afroasiatic origin to varying extents. Writing in 2004, John Huehnergard notes the great difficulty in establishing cognate sets across the family. Identifying cognates is difficult because the languages in question are often separated by thousands of years of development and many languages within the family have long been in contact with each other, raising the possibility of loanwords. Work is also hampered because of the poor state of documentation of many languages.
There are two etymological dictionaries of Afroasiatic, one by Christopher Ehret, and one by Vladimir Orel and Olga Stolbova, both from 1995. Both works provide highly divergent reconstructions and have been heavily criticized by other scholars. Andrzej Zaborski refers to Orel and Stolbova's reconstructions as "controversial", and Ehret's as "not acceptable to many scholars". Tom Güldemann argues that much comparative work in Afroasiatic suffers from not attempting first to reconstruct smaller units within the individual branches, but instead comparing words in the individual languages. Nevertheless, both dictionaries agree on some items and some proposed cognates are uncontroversial. Such cognates tend to rely on relatively simple sound correspondences.

Andorra
Andorra, officially the Principality of Andorra, is a sovereign landlocked country on the Iberian Peninsula, in the eastern Pyrenees in Western Europe, bordered by France to the north and Spain to the south. Believed to have been created by Charlemagne, Andorra was ruled by the count of Urgell until 988, when it was transferred to the Roman Catholic Diocese of Urgell. The present principality was formed by a charter in 1278. It is currently headed by two co-princes: the Bishop of Urgell in Catalonia, Spain, and the president of France. Its capital and largest city is Andorra la Vella.
Andorra is the sixth-smallest state in Europe, with an area of and a population of approximately 87,486. The Andorran people are a Romance ethnic group closely related to Catalans. Andorra is the world's 16th-smallest country by land and 11th-smallest by population. Its capital, Andorra la Vella, is the highest capital city in Europe, at an elevation of above sea level. The official language is Catalan, but Spanish, Portuguese, and French are also commonly spoken.

Tourism in Andorra brings approximately 8 million visitors to the country annually. Andorra is not a member state of the European Union. It has been a member of the Council of Europe and of the United Nations since 1993.
Etymology.
The origin of the word Andorra is unknown, although several hypotheses have been proposed. The oldest is one put forward by the Greek historian Polybius ("Histories" III, 35, 1), who describes the Andosins, an Iberian Pre-Roman tribe, as historically located in the valleys of Andorra and facing the Carthaginian army in its passage through the Pyrenees during the Punic Wars. The word Andosini or Andosins () may derive from the Basque , meaning "big" or "giant". The Andorran toponymy shows evidence of Basque language in the area. Another theory suggests that the word Andorra may derive from the old word Anorra that contains the Basque word ("water").
Another theory suggests that Andorra may derive from Arabic (), indicating a vast land which is located among mountains or a thickly wooded place (with being the definite article). When the Moors conquered the Iberian Peninsula, the valleys of the High Pyrenees were covered by large tracts of forest. These regions were not administered by Muslims, because of the geographic difficulty of direct rule.
|
Other theories suggest that the term derives from the Navarro-Aragonese "andurrial", which means "land covered with bushes" or "scrubland".
The folk etymology holds that Charlemagne had named the region as a reference to the Biblical Canaanite valley of Endor or Andor (where the Midianites had been defeated), a name bestowed by his heir and son Louis the Pious after defeating the Moors in the "wild valleys of Hell".
History.
Prehistory.
La Balma de la Margineda, found by archaeologists at Sant Julià de Lòria, was settled in 9,500 BCE as a passing place between the two sides of the Pyrenees. The seasonal camp was perfectly located for hunting and fishing by the groups of hunter-gatherers from Ariege and Segre.
During the Neolithic, a group of people moved to the Valley of Madriu (the present-day Natural Park located in Escaldes-Engordany declared UNESCO World Heritage Site) as a permanent camp in 6640 BCE. The population of the valley grew cereals, raised domestic livestock, and developed commercial trade with people from Ségre and Occitania.
|
Other archaeological deposits include the Tombs of Segudet (Ordino) and Feixa del Moro (Sant Julià de Lòria), both dated in 4900–4300 BCE as an example of the Urn culture in Andorra. The model of small settlements began to evolve to complex urbanism during the Bronze Age. Metallurgical items of iron, ancient coins, and reliquaries can be found in the ancient sanctuaries scattered around the country.
The sanctuary of Roc de les Bruixes (Stone of the Witches) is perhaps the most important archeological complex of this age in Andorra, located in the parish of Canillo, about the rituals of funerals, ancient scripture and engraved stone murals.
Iberian and Roman Andorra.
The inhabitants of the valleys were traditionally associated with the Iberians and historically located in Andorra as the Iberian tribe Andosins or Andosini () during the 7th and 2nd centuries BC. Influenced by the Celtic, Aquitanian, Basque and Iberian languages, the locals developed some current toponyms. Early writings and documents relating to this group of people goes back to the second century BC by the Greek writer Polybius in his "Histories" during the Punic Wars.
|
Some of the most significant remains of this era are the Castle of the Roc d'Enclar (part of the early Marca Hispanica), l'Anxiu in Les Escaldes and Roc de L'Oral in Encamp.
The presence of Roman influence is recorded from the 2nd century BCE to the 5th century CE. The places with the most Roman presence are in Camp Vermell (Red Field) in Sant Julià de Lòria, and in some places in Encamp and in the Roc d'Enclar. People continued trading, mainly with wine and cereals, with the Roman cities of Urgellet (the present-day La Seu d'Urgell) and across Segre through the "via romana" Strata Ceretana (also known as Strata Confluetana).
Visigoths and Carolingians: the legend of Charlemagne.
After the fall of the Roman Empire, Andorra came under the influence of the Visigoths, the Kingdom of Toledo, and the Diocese of Urgell. The Visigoths remained in the valleys for 200 years, during which time Christianity spread. When the Muslim Empire of Al-Andalus replaced the ruling Visigoths in most of the Iberian Peninsula, Andorra was sheltered from these Arab invaders by the Franks.
|
Tradition holds that Charles the Great (Charlemagne) granted a charter to the Andorran people for a contingent of 5,000 soldiers under the command of Marc Almugaver, in return for fighting against the Moors near Porté-Puymorens (Cerdanya).
Andorra remained part of the Frankish "Marca Hispanica", the buffer zone between the Frankish Empire and the Muslim territories, Andorra being part of the territory ruled by the Count of Urgell and eventually the bishop of the Diocese of Urgell. Tradition also holds that it was guaranteed by the son of Charlemagne, Louis the Pious, writing the "Carta de Poblament" or a local municipal charter .
In 988, Count Borrell II of Urgell gave the Andorran valleys to the Diocese of Urgell in exchange for land in Cerdanya. Since then, the bishop of Urgell, based in Seu d'Urgell, has been co-prince of Andorra.
The first document that mentions Andorra as a territory is the "Acta de Consagració i Dotació de la Catedral de la Seu d'Urgell" (Deed of Consecration and Endowment of the Cathedral of La Seu d'Urgell). The document, dated 839, depicts the six old parishes of the Andorran valleys that made up the country's administrative division.

Middle Ages: The Paréages and the founding of the Co-Principality.
Before 1095, Andorra had no military protection, and the bishop of Urgell, who knew that the count of Urgell wanted to reclaim the Andorran valleys, asked the Lord of Caboet for help and protection. In 1095, the lord of Caboet and the bishop of Urgell signed under oath a declaration of their co-sovereignty over Andorra. Arnalda de Caboet, daughter of Arnau of Caboet, married the viscount of Castellbò. Their daughter, Ermessenda de Castellbò, married the count of Foix, Roger-Bernard II. Roger-Bernard II and Ermessenda shared rule over Andorra with the bishop of Urgell.
In the 13th century, a military dispute arose between the bishop of Urgell and the count of Foix as aftermath of the Cathar Crusade. The conflict was resolved in 1278 with the mediation of the king of Aragon, Peter III, between the bishop and the count, by the signing of the first paréage, which provided that Andorra's sovereignty be shared between the count of Foix (whose title would ultimately transfer to the French head of state) and the bishop of Urgell, in Catalonia. This gave the principality its territory and political form.
|
A second paréage was signed in 1288 after a dispute when the count of Foix ordered the construction of a castle in Roc d'Enclar. The document was ratified by the noble notary Jaume Orig of Puigcerdà, and construction of military structures in the country was prohibited.
In 1364, the political organisation of the country named the figure of the syndic (now spokesman and president of the parliament) as representative of the Andorrans to their co-princes, making possible the creation of local departments (comuns, quarts and veïnats). After being ratified by Bishop Francesc Tovia and Count John I, the Consell de la Terra or Consell General de les Valls (General Council of the Valleys) was founded in 1419, the second oldest parliament in Europe. The syndic Andreu d'Alàs and the General Council organised the creation of the Justice Courts (La Cort de Justicia) in 1433 with the co-princes and the collection of taxes like foc i lloc (literally "fire and site", a national tax active since then).
Although there are remains of ecclesiastical works dating before the 9th century (Sant Vicenç d'Enclar or Església de Santa Coloma), Andorra developed exquisite Romanesque Art during the 9th through 14th centuries, particularly in the construction of churches, bridges, religious murals and statues of the Virgin and Child (Our Lady of Meritxell being the most important). Nowadays, the Romanesque buildings that form part of Andorra's cultural heritage stand out in a remarkable way, with an emphasis on Església de Sant Esteve, Sant Joan de Caselles, Església de Sant Miquel d'Engolasters, Sant Martí de la Cortinada and the medieval bridges of Margineda and Escalls among many others.

The Catalan Pyrenees were embryonic of the Catalan language at the end of the 11th century. Andorra was influenced by this language, which was adopted locally decades before it expanded to the rest of the Crown of Aragon.
The local economy during the Middle Ages was based on livestock, agriculture, furs and weavers. Later, at the end of the 11th century, the first iron foundries began to appear in Northern Parishes like Ordino, much appreciated by the master artisans who developed the art of the forges, an important economic activity in the country from the 15th century.
16th to 18th centuries.
In 1601 the Tribunal de Corts (High Court of Justice) was created as a result of Huguenot rebellions in France, Inquisition courts coming from Spain and witchcraft-related beliefs native to the area, in the context of the Reformation and Counter-Reformation.
With the passage of time, the co-title to Andorra passed to the kings of Navarre. After Henry III of Navarre became king of France, he issued an edict in 1607 that established the head of the French state and the bishop of Urgell as Co-Princes of Andorra, a political arrangement that still holds.
|
During 1617, communal councils form the sometent (popular militia or army) to deal with the rise of bandolerisme (brigandage) and the Consell de la Terra was defined and structured in terms of its composition, organisation and competences current today.
Andorra continued with the same economic system that it had during the 12th–14th centuries with a large production of metallurgy (fargues, a system similar to Farga Catalana) and with the introduction of tobacco circa 1692 and import trade. In 1371 and 1448, the co-princes ratified the fair of Andorra la Vella, the most important annual national festival commercially ever since.
The country had a unique and experienced guild of weavers, Confraria de Paraires i Teixidors, in Escaldes-Engordany. Founded in 1604, it took advantage of the local thermal waters. By this time, the country was characterised by the social system of prohoms (wealthy society) and casalers (rest of the population with smaller economic acquisition), deriving from the tradition of pubilla and hereu.
|
Three centuries after its foundation, the Consell de la Terra located its headquarters and the Tribunal de Corts in Casa de la Vall in 1702. The manor house built in 1580 served as a noble fortress of the Busquets family. Inside the parliament was placed the Closet of the six keys (Armari de les sis claus), representative of each Andorran parish, where the Andorran constitution and other documents and laws were later kept.
In both the Reapers' War and the War of the Spanish Succession, the Andorran people (while professing to be a neutral country) supported the Catalans who saw their rights reduced in 1716. The reaction was the promotion of Catalan writings in Andorra, with cultural works such as the "Book of Privileges" ("Llibre de Privilegis de 1674"), "Manual Digest" (1748) by Antoni Fiter i Rossell or the "Polità andorrà" (1763) by Antoni Puig.
19th century: the New Reform and the Andorran Question.
After the French Revolution, Napoleon I reestablished the Co-Principate in 1809 and removed the French medieval title. In 1812–1813, the First French Empire annexed Catalonia during the Peninsular War () and divided the region into four départements, with Andorra as a part of the district of Puigcerdà. In 1814, an imperial decree reestablished the independence and economy of Andorra.
|
During this period, Andorra's late medieval institutions and rural culture remained largely unchanged. In 1866, the syndic Guillem d'Areny-Plandolit led the reformist group in a Council General of 24 members elected by suffrage limited to heads of families. The Council General replaced the aristocratic oligarchy that previously ruled the state.
The New Reform () began after ratification by both Co-Princes and established the basis of the constitution and symbolssuch as the tricolour flagof Andorra. A new service economy arose as a demand of the valley inhabitants and began to build infrastructure such as hotels, spa resorts, roads and telegraph lines.
The authorities of the Co-Princes banned casinos and betting houses throughout the country. The ban resulted in an economic conflict and the Revolution of 1881, which began when revolutionaries assaulted the house of the syndic on 8 December 1880, and established the Provisional Revolutionary Council led by Joan Pla i Calvo and Pere Baró i Mas. The Provisional Revolutionary Council allowed for the construction of casinos and spas by foreign companies. From 7 to 9 June 1881, the loyalists of Canillo and Encamp reconquered the parishes of Ordino and La Massana by establishing contact with the revolutionary forces in Escaldes-Engordany. After a day of combat the Treaty of the Bridge of Escalls was signed on 10 June. The council was replaced and new elections were held. The economic situation worsened, as the populace was divided over the – the "Andorran Question" in relation to the Eastern Question. The struggles continued between pro-bishops, pro-French, and nationalists based on the troubles of Canillo in 1882 and 1885.
|
Andorra participated in the cultural movement of the Catalan Renaixença. Between 1882 and 1887, the first academic schools were formed where trilingualism coexisted with the official language, Catalan. Romantic authors from France and Spain reported the awakening of the national consciousness of the country. Jacint Verdaguer lived in Ordino during the 1880s where he wrote and shared works related to the Renaixença with writer and photographer Joaquim de Riba.
In 1848, Fromental Halévy had premiered the opera "Le val d'Andorre" to great success in Europe, where the national consciousness of the valleys was exposed in the romantic work during the Peninsular War.
20th and 21st century: Modernisation of the country and constitutional Andorra.
In 1933 France occupied Andorra following social unrest which occurred before elections due to the Revolution of 1933 and the FHASA strikes (Vagues de FHASA); the revolt led by Joves Andorrans (a labour union group related to the Spanish CNT and FAI) called for political reforms, the universal suffrage vote of all Andorrans and acted in defence of the rights of local and foreign workers during the construction of FHASA's hydroelectric power station in Encamp. On 5 April 1933 Joves Andorrans seized the Andorran Parliament. These actions were preceded by the arrival of Colonel René-Jules Baulard with 50 gendarmes and the mobilisation of 200 local militias or sometent led by the Síndic Francesc Cairat.
|
On 6 July 1934, adventurer and nobleman Boris Skossyreff, with his promise of freedoms and modernisation of the country and wealth through the establishment of a tax haven and foreign investments, received the support of the members of the General Council to proclaim himself the sovereign of Andorra. On 8 July 1934 Boris issued a proclamation in Urgell, declaring himself Boris I, King of Andorra, simultaneously declaring war on the Bishop of Urgell and approving the King's constitution on 10 July. He was arrested by the Co-Prince and Bishop Justí Guitart i Vilardebó and their authorities on 20 July and ultimately expelled from Spain. From 1936 until 1940, a French military detachment of Garde Mobile led by well-known Colonel René-Jules Baulard was garrisoned in Andorra to secure the principality against disruption from the Spanish Civil War and Francoist Spain and also face the rise of Republicanism in the aftermath of the 1933 Revolution. During the Spanish Civil War, the inhabitants of Andorra welcomed refugees from both sides, and many of them settled permanently in the country thus contributing to the subsequent economic boom and the entry into the capitalist era of Andorra. Francoist troops reached the Andorran border in the later stages of the war.
|
During World War II, Andorra remained neutral and was an important smuggling route between Vichy France and Francoist Spain. Many Andorrans criticised the passivity of the General Council for impeding both the entry and expulsion of foreigners and refugees, committing economic crimes, reducing the rights of citizens and sympathy with Francoism. General Council members justified the council's political and diplomatic actions as necessary for Andorra's survival and the protection of its sovereignty. Andorra was relatively unscathed by the two world wars and the Spanish Civil War. Certain groups formed to help victims of oppression in Nazi-occupied countries, while participating in smuggling to help Andorra survive. Among the most prominent was the Hostal Palanques Evasion Network Command, which, in contact with the British MI6, helped almost 400 fugitives, among whom were Allied military personnel. The Command remained active between 1941 and 1944, although there were struggles with pro-Axis informers and Gestapo agents in Andorra.
|
In the capital city there was a smuggling black market of propaganda, culture and cinematic art not favourable to totalitarian regimes, promulgated in such places as the Hotel Mirador or the Casino Hotel, as a meeting place for Free French forces and a route for escorting crashed Allied pilots out of Europe. The network was maintained after the war, when film societies were formed, where movies, music and books censored in Franco's Spain were imported, becoming an anti-censorship attraction for the Catalan or foreign public even within Andorra. Andorran Group (Agrupament Andorrà), an anti-fascist organisation linked to the Occitanie's French Resistance, accused the French representative (veguer) of collaboration with Nazism.
The Andorran opening to the capitalist economy resulted in two axes: mass tourism and the country's tax exemption. The first steps towards the capitalist boom date from the 1930s, with the construction of FHASA and the creation of professional banking with Banc Agrícol (1930) and Crèdit Andorrà (1949), later with Banca Mora (1952), Banca Cassany (1958) and SOBANCA (1960). Shortly after, activities such as skiing and shopping become a tourist attraction, with the inauguration of ski resorts and cultural entities in the late 1930s. All in all, a renovated hotel industry has developed. In April 1968 a social health insurance system was created (CASS).
|
The Andorran government necessarily involved planning, projection and forecasts for the future: with the official visit of the French co-prince Charles de Gaulle in 1967 and 1969, it was given approval for the economic boom and national demands within the framework of human rights and international openness.
Andorra experienced an era commonly known as the "Andorran dream" (similar to the American Dream) along with the Trente Glorieuses: the mass culture rooted the country experiencing radical changes in the economy and culture. Proof of this was Ràdio Andorra, the top musical radio station in Europe in this period, with guests and speakers of great importance promoting musical hits of chanson française, swing, rhythm & blues, jazz, rock and roll and American country music. During this period Andorra achieved a GDP per capita and a life expectancy higher than the most standard countries of the current economy.
Given its relative isolation, Andorra has existed outside the mainstream of European history, with few ties to countries other than France, Spain and Portugal. But in recent times its thriving tourist industry, along with developments in transport and communications, have removed the country from its isolation. Since 1976 the country has seen the need to reform Andorran institutions due to anachronisms in sovereignty, human rights and the balance of powers as well as the need to adapt legislation to modern demands. In 1982 a first separation of powers took place when instituting the Govern d'Andorra, under the name of the executive board (Consell Executiu), chaired by the first prime minister Òscar Ribas Reig with the co-princes' approval. In 1989 the Principality signed an agreement with the European Economic Community to regularise trade relations.
|
Its political system was modernised in 1993 after the Andorran constitutional referendum, when the constitution was drafted by the co-princes and the General Council and approved on 14 March by 74.2% of voters, with a 76% turnout. The first elections under the new constitution were held later in the year. The same year, Andorra became a member of the United Nations and the Council of Europe.
Andorra formalised diplomatic relations with the United States in 1996, participating in the 51st UN General Assembly. First General Syndic Marc Forné took part in a speech in Catalan in the General Assembly to defend the reform of the organisation, and after three days he took part in the Parliamentary Assembly of the Council of Europe to defend Andorra's linguistic rights and economy. In 2006 a monetary agreement with the European Union was formalised that allows Andorra to use the euro officially, as well as minting its own euro coins.
Politics.
Andorra is a parliamentary co-principality with the bishop of Urgell and the president of France as co-princes. This peculiarity makes the president of France, in his capacity as prince of Andorra, an elected monarch, although he is not elected by a popular vote of the Andorran people. The politics of Andorra take place in a framework of a parliamentary representative democracy with a unicameral legislature, and of a pluriform multi-party system. The prime minister is the chief executive.
|
The current prime minister is Xavier Espot Zamora of the Democrats for Andorra (DA). Executive power is exercised by the government. Legislative power is vested in both government and parliament.
The Parliament of Andorra is known as the General Council. The General Council consists of between 28 and 42 councillors. The councillors serve for four-year terms, and elections are held between the 30th and 40th days following the dissolution of the previous Council.
Half are elected in equal numbers by each of the seven administrative parishes, and the other half of the councillors are elected in a single national constituency. Voters vote for parties, not candidates; a voter votes for a party for the parish councillors and a party for the at-large councilors, and the winners come from party lists. Fifteen days after the election, the councillors hold their inauguration. During this session, the General Syndic, who is the head of the General Council, and the Subsyndic General, his assistant, are elected. Eight days later, the Council convenes once more. During this session, the prime minister is chosen from among the councillors.
|
Candidates can be proposed by a minimum of one-fifth of the councillors. The Council then elects the candidate with the absolute majority of votes to be prime minister. The Syndic General then notifies the co-princes, who in turn appoint the elected candidate as the prime minister of Andorra. The General Council is also responsible for proposing and passing laws. Bills may be presented to the council as Private Members' Bills by three of the local Parish Councils jointly or by at least one tenth of the citizens of Andorra.
The council also approves the annual budget of the principality. The government must submit the proposed budget for parliamentary approval at least two months before the previous budget expires. If the budget is not approved by the first day of the next year, the previous budget is extended until a new one is approved. Once any bill is approved, the Syndic General is responsible for presenting it to the co-princes so that they may sign and enact it.
If the prime minister is not satisfied with the council, he may request that the co-princes dissolve the council and order new elections. In turn, the councillors have the power to remove the prime minister from office. After a motion of censure is approved by at least one-fifth of the councillors, the council will vote and if it receives the absolute majority of votes, the prime minister is removed.
|
Law and criminal justice.
The judiciary is composed of the Magistrates Court, the Criminal Law Court, the High Court of Andorra, and the Constitutional Court. The High Court of Justice is composed of five judges: one appointed by the prime minister, one each by the co-princes, one by the Syndic General, and one by the judges and magistrates. It is presided over by the member appointed by the Syndic General and the judges hold office for six-year terms.
The magistrates and judges are appointed by the High Court, as is the president of the Criminal Law Court. The High Court also appoints members of the Office of the Attorney General. The Constitutional Court is responsible for interpreting the Constitution and reviewing all appeals of unconstitutionality against laws and treaties. It is composed of four judges, one appointed by each of the co-princes and two by the General Council. They serve eight-year terms. The Court is presided over by one of the judges on a two-year rotation so that each judge at one point will preside over the Court.
|
Foreign relations, defence and security.
Andorra does not have its own armed forces, although there is a small ceremonial army. Responsibility for defending the nation rests primarily with France and Spain. However, in case of emergencies or natural disasters, the Sometent (an alarm) is called and all able-bodied men between 21 and 60 of Andorran nationality must serve. This is why all Andorrans, and especially the head of each house (usually the eldest able-bodied man of a house) should, by law, keep a rifle, even though the law also states that the police will offer a firearm in case of need. Andorra is a full member of the United Nations (UN), the Organisation for Security and Co-operation in Europe (OSCE), and has a special agreement with the European Union (EU). After the constitution was ratified, Andorra would later establish diplomatic relations with their major allies aside from neighbours France and Spain such as the United Kingdom in 1994 and the United States in 1995. It also has observer status at the World Trade Organisation (WTO). On 16 October 2020, Andorra became the 190th member of the International Monetary Fund (IMF), during the COVID-19 pandemic.
|
Military.
Andorra has a small army, which has historically been raised or reconstituted at various dates, but has never in modern times amounted to a standing army. The basic principle of Andorran defence is that all able-bodied men are available to fight if called upon by the summoning of the Sometent (a civil defence organisation of Andorra, made up of the heads of households). The Sometent was used sparingly against French "Lutheran" raids during the late 16th century. Being a landlocked country, Andorra has no navy.
Before World War I, Andorra maintained an armed militia force of about 600 part-time militiamen under the supervision of a Captain (Capità or Cap de Sometent) and a Lieutenant (Desener or Lloctinent del Capità). This body was not liable for service outside the principality and was commanded by two officials (veguers) appointed by France and the Bishop of Urgell.
In the modern era, the army has consisted of a very small body of volunteers willing to undertake ceremonial duties. Uniforms and weaponry were handed down from generation to generation within families and communities.
|
The army's role in internal security was largely taken over by the formation of the Police Corps of Andorra in 1931. Brief civil disorder associated with the elections of 1933 led to assistance being sought from the French National Gendarmerie, with a detachment resident in Andorra for two months under the command of René-Jules Baulard. The Andorran Police was reformed in the following year, with eleven soldiers appointed to supervisory roles. The force consisted of six corporals, one for each parish (although there are currently seven parishes, there were only six until 1978), plus four junior staff officers to co-ordinate action, and a commander with the rank of major. It was the responsibility of the six corporals, each in his own parish, to be able to raise a fighting force from among the able-bodied men of the parish.
The only permanent section of the present-day Sometent is a twelve-man ceremonial unit. However, all able-bodied men are technically available for military service, with a requirement for each family to have access to a firearm. An area weapon, such as a shotgun per household, is unregulated; however, ranged weapons, such as pistols and rifles, require a licence. The army has not fought for more than 700 years, and its main responsibility is to present the flag of Andorra at official ceremonial functions. According to Marc Forné Molné, Andorra's military budget is strictly from voluntary donations, and the availability of full-time volunteers.
|
The only more recent general emergency call to the Sometent was given during the floods of 1982 in the Catalan Pyrenees (when 12 Andorran citizens perished), to help the population and establish a public order along with the local police units.
Andorra in the Council of Europe.
Andorra is one of the 46 member states of the Council of Europe, having joined on 10 November 1994. Through its membership in the Council of Europe, Andorra is or has been involved in the following areas:
Andorra's representation in the Council includes:
For 2025, the Council of Europe's budget is €655.7 million, with Andorra contributing €368,842.
Police Corps.
Andorra maintains a small but modern and well-equipped internal police force, with around 240 police officers supported by civilian assistants. The principal services supplied by the corps are uniformed community policing, criminal detection, border control, and traffic policing. There are also small specialist units including police dogs, mountain rescue, and a bomb disposal team.
|
GIPA.
The ' (GIPA) is a small special forces squad trained in counter-terrorism, and hostage recovery tasks. Although it is the closest in style to an active military force, it is part of the Police Corps, and not the army. As terrorist and hostage situations are a rare threat to the country, the GIPA is commonly assigned to prisoner escort duties, and at other times to routine policing.
Fire brigade.
The Andorran Fire Brigade, with headquarters at Santa Coloma, operates from four modern fire stations, and has a staff of around 120 firefighters. The service is equipped with 16 heavy appliances (fire tenders, turntable ladders, and specialist four-wheel drive vehicles), four light support vehicles (cars and vans) and four ambulances.
Historically, the families of the six ancient parishes of Andorra maintained local arrangements to assist each other in fighting fires. The first fire pump purchased by the government was acquired in 1943. Serious fires which lasted for two days in December 1959 led to calls for a permanent fire service, and the Andorran Fire Brigade was formed on 21 April 1961.
|
The fire service maintains full-time cover with five fire crews on duty at any time: two at the brigade's headquarters in Santa Coloma, and one crew at each of the other three fire stations.
Geography.
Parishes.
Andorra consists of seven parishes:
Physical geography.
Due to its location in the eastern Pyrenees mountain range, Andorra consists predominantly of rugged mountains, the highest being the Coma Pedrosa at , and the average elevation of Andorra is . These are dissected by three narrow valleys in a Y shape that combine into one as the main stream, the Gran Valira river, leaves the country for Spain (at Andorra's lowest point of ). Andorra's land area is .
Environment.
Phytogeographically, Andorra belongs to the Atlantic European province of the Circumboreal Region within the Boreal Kingdom. According to the WWF, the territory of Andorra belongs to the ecoregion of Pyrenees conifer and mixed forests. Andorra had a 2018 Forest Landscape Integrity Index mean score of 4.45/10, ranking it 127th globally out of 172 countries. In Andorra forest cover is around 34% of the total land area, equivalent to 16,000 hectares (ha) of forest in 2020, which was unchanged from 1990. In 2020, naturally regenerating forest covered 16,000 hectares (ha) and planted forest covered 0 hectares (ha). Of the naturally regenerating forest 0% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 0% of the forest area was found within protected areas.

Important Bird Area.
The whole country has been recognised as a single Important Bird Area (IBA) by BirdLife International, because it is important for forest and mountain birds and supports populations of red-billed choughs, citril finches and rock buntings.
Climate.
Andorra has alpine, continental and oceanic climates, depending on altitude. Its higher elevation means there is, on average, more snow in winter and it is slightly cooler in summer. The diversity of landmarks, the different orientation of the valleys and the irregularity relief typical of the Mediterranean climates make the country have a great diversity of microclimates that hinder the general dominance of the high mountain climate. The great differences of altitude in the minimum and maximum points, together with the influence of a Mediterranean climate, develop the climate of the Andorran Pyrenees.
When in precipitation, a global model characterised by convective and abundant rains can be defined during spring and summer, which can last until autumn (May, June and August are usually the rainiest months). In winter, however, it is less rainy, except in the highlands, subject to the influence of fronts from the Atlantic, which explains the great amount of snowfall in the Andorran mountains. The temperature regime is characterised, broadly, by a temperate summer and a long and cold winter, in accordance with the mountainous condition of the Principality.
|
As a small mountainous country, Andorra is highly vulnerable to climate change. Temperatures in its high-altitude regions have risen by about 0.17 °C per decade, while annual rainfall has decreased by 49 mm. These shifts are impacting water resources and snow cover, which are key elements for Andorra's tourism-driven economy. The number of days with enough snow for skiing is declining, and the snow line is retreating to higher altitudes.
Although its national greenhouse gas emissions are one of the lowest in the world (534 thousand tonnes emitted in 2023), Andorra has a strong climate change mitigation strategy, with a focus on renewable energy and energy efficiency. In its Nationally Determined Contribution, Andorra has committed to reducing its emissions by 55% by 2030, and to carbon neutrality by 2050. However, the adaptation part of the strategy is still in early stages and may be difficult and costly to implement. Given the country's reliance on tourism, speeding up adaptation is essential for building a more resilient economy.

Economy.
Tourism, the mainstay of Andorra's economy, accounts for roughly 80% of GDP. An estimated 8 million tourists visit annually, attracted by Andorra's duty-free status and by its summer and winter resorts.
One of the main sources of income in Andorra is from ski resorts, which total over of ski grounds. The sport brings in over 7 million visitors annually and an estimated 340 million euros per year, sustaining 2,000 direct and 10,000 indirect jobs at present since 2007.
The banking sector, with its tax haven status, also contributes substantially to the economy with revenues raised exclusively through import tariffs (the financial and insurance sector accounts for approximately 19% of GDP). However, during the European sovereign-debt crisis of the 21st century, the tourist industry suffered a decline, partly caused by a drop in the prices of goods in Spain, undercutting duty-free shopping and increasing unemployment. On 1 January 2012, a business tax of 10% was introduced, followed by a sales tax of 2% a year later, which raised just over 14 million euros in its first quarter.
|
Agricultural production is limited; only 1.7% of the land is arable, and most food has to be imported. Some tobacco is grown locally. The principal livestock activity is domestic sheep raising. Manufacturing output consists mainly of cigarettes, cigars, and furniture. Andorra's natural resources include hydroelectric power, mineral water, timber, iron ore, and lead.
Andorra is not a member of the European Union, but enjoys a special relationship with it, such as being treated as an EU member for trade in manufactured goods (no tariffs) and as a non-EU member for agricultural products. Andorra lacked a currency of its own and used both the French franc and the Spanish peseta in banking transactions until 31 December 1999, when both currencies were replaced by the EU's single currency, the euro. Coins and notes of both the franc and the peseta remained legal tender in Andorra until 31 December 2002. Andorra negotiated to issue its own euro coins, beginning in 2014.
Andorra has historically had one of the world's lowest unemployment rates. In 2023 it stood at 1.5%.
|
On 31 May 2013, it was announced that Andorra intended to legislate for the introduction of an income tax by the end of June, against a background of increasing dissatisfaction with the existence of tax havens among EU members. The announcement was made following a meeting in Paris between the Prime Minister Antoni Martí and the French President and Prince of Andorra François Hollande. Hollande welcomed the move as part of a process of Andorra "bringing its taxation in line with international standards".
By the mid-2010s, the financial system comprised five banking groups, one specialised credit entity, eight investment undertaking management entities, three asset management companies, and 29 insurance companies, 14 of which are branches of foreign insurance companies authorised to operate in the principality. The last mergers between banks took place in 2022, bringing the Andorran financial sector to currently have 3 active banking groups.
Demographics.
Population.
The population of Andorra is estimated at (). The Andorrans are a Romance ethnic group of originally Catalan descent. The population has grown from 5,000 in 1900.
|
Two-thirds of residents lack Andorran nationality and do not have the right to vote in communal elections. Moreover, they are not allowed to be elected as prime minister or to own more than 33% of the capital stock of a privately held company.
The largest national groups in Andorra are Spanish (34.3%), Andorrans (32.1%), Portuguese (10%), and French (5.6%). The remaining 18% of the population includes British, Dutch, Germans, Italians and other Europeans, as well as Argentinians, Chileans, Indians, Moroccans and Uruguayans.
Languages.
The historic and official language is Catalan, a Romance language. The Andorran government encourages the use of Catalan. It funds a Commission for Catalan Toponymy in Andorra (Catalan: ), and provides free Catalan classes to assist immigrants. Andorran television and radio stations use Catalan.
Because of immigration, historical links, and close geographic proximity, Spanish, Portuguese and French are commonly spoken. Most Andorran residents can speak one or more of these, in addition to Catalan. English is less commonly spoken among the general population, though it is understood to varying degrees in the major tourist resorts. Andorra is one of only four European countries (together with France, Monaco, and Turkey) that have never signed the Council of Europe Framework Convention on National Minorities.
|
Religion.
Few official statistics are available on religion; estimates of the Catholic population in 2020 range from 89.5% to 99.21%. The patron saint is Our Lady of Meritxell. There are also members of various Protestant denominations and small numbers of Hindus, and Bahá'ís. In 2022 there were approximately 2000 Muslims and roughly 100 Jews.
Education.
The Qualified Education Law ("llei qualificada d'educació") of Andorra was passed in 1993. It guarantees free, public education from age four until the end of compulsory schooling.
Schools.
Children between the ages of 6 and 16 are required by law to have full-time education. Education up to secondary level is provided free of charge by the government.
There are three systems of school, Andorran, French and Spanish, which use Catalan, French and Spanish languages respectively, as the main language of instruction. Parents may choose which system their children attend. All schools are built and maintained by Andorran authorities, but teachers in the French and Spanish schools are paid for the most part by France and Spain. 39% of Andorran children attend Andorran schools, 33% attend French schools, and 28% Spanish schools.
|
University of Andorra.
The Universitat d'Andorra (UdA) is the state public university and is the only university in Andorra. It was established in 1997. The university provides first-level degrees in nursing, computer science, business administration, and educational sciences, in addition to higher professional education courses. The only two graduate schools in Andorra are the Nursing School and the School of Computer Science, the latter having a PhD programme.
Virtual Studies Centre.
The geographical complexity of the country as well as the small number of students prevents the University of Andorra from developing a full academic programme, and it serves principally as a centre for virtual studies, connected to Spanish and French universities. The Virtual Studies Centre (Centre d'Estudis Virtuals) at the university runs approximately 20 different academic degrees at both undergraduate and postgraduate levels in fields including tourism, law, Catalan philology, humanities, psychology, political sciences, audiovisual communication, telecommunications engineering, and East Asia studies. The centre also runs various postgraduate programmes and continuing-education courses for professionals.

Transport.
Until the 20th century, Andorra had very limited transport links to the outside world, and development of the country was affected by its physical isolation. Even now, the nearest major airports at Toulouse and Barcelona are both three hours' drive from Andorra.
Andorra has a road network of , of which is unpaved. The two main roads out of Andorra la Vella are the CG-1 to the Spanish border near Sant Julià de Lòria, and the CG-2 to the French border via the Envalira Tunnel near El Pas de la Casa. Bus services cover all metropolitan areas and many rural communities, with services on most major routes running half-hourly or more frequently during peak travel times. There are frequent long-distance bus services from Andorra to Barcelona and Toulouse, plus a daily tour from the former city. Bus services mostly are run by private companies, but some local ones are operated by the government.
There are no airports for fixed-wing aircraft within Andorra's borders but there are, however, heliports in La Massana (Camí Heliport), Arinsal and Escaldes–Engordany with commercial helicopter services and an airport located in the neighbouring Spanish comarca of Alt Urgell, south of the Andorran–Spanish border. Since July 2015, Andorra–La Seu d'Urgell Airport has operated commercial flights to Madrid and Palma de Mallorca, and is the main hub for Andorra Airlines.
|
Nearby airports located in Spain and France provide access to international flights for the principality. The nearest airports are at Perpignan, France ( from Andorra) and Lleida, Spain ( from Andorra). The largest nearby airports are at Toulouse, France ( from Andorra and Barcelona, Spain ( from Andorra). There are hourly bus services from both Barcelona and Toulouse airports to Andorra.
The nearest railway station is Andorre-L'Hospitalet station east of Andorra which is on the -gauge line from Latour-de-Carol () southeast of Andorra, to Toulouse and on to Paris by the French high-speed trains. This line is operated by the SNCF. Latour-de-Carol has a scenic trainline to Villefranche-de-Conflent, as well as the SNCF's -gauge line connecting to Perpignan, and the Renfe's -gauge line to Barcelona. There are also direct Intercités de nuit trains between L'Hospitalet-près-l'Andorre and Paris on certain dates.
Media and telecommunications.
In Andorra, mobile and fixed telephone and internet services are operated exclusively by the Andorran national telecommunications company, SOM, also known as Andorra Telecom (STA). The same company also manages the technical infrastructure for national broadcasting of digital television and radio. In 2010 Andorra became the first country to provide a direct optical fiber link to all homes (FTTH) and businesses.
|
The first commercial radio station to broadcast was Radio Andorra, which was active from 1939 to 1981. On 12 October 1989, the General Council established radio and television as essential public services creating and managing the entity ORTA, becoming on 13 April 2000, in the public company Ràdio i Televisió d'Andorra (RTVA). In 1990, the public radio was founded on the Radio Nacional d'Andorra. As an autochthonous television channel, there is only the national public television network Andorra Televisió, created in 1995. Additional TV and radio stations from Spain and France are available via digital terrestrial television and IPTV.
There are three national newspapers, "Diari d'Andorra", "El Periòdic d'Andorra", and "Bondia" as well as several local newspapers. The history of the Andorran press begins in the period between 1917 and 1937 with the appearance of several periodicals papers such as "Les Valls d'Andorra" (1917), "Nova Andorra" (1932) and "Andorra Agrícola" (1933). In 1974, the "Poble Andorrà" became the first regular newspaper in Andorra. There is also an amateur radio society and news agency ANA with independent management.

Culture.
Andorra is home to folk dances like the contrapàs and marratxa, which survive in Sant Julià de Lòria especially. Andorran folk music has similarities to the music of its neighbours, but is especially Catalan in character, especially in the presence of dances such as the sardana. Other Andorran folk dances include contrapàs in Andorra la Vella and Saint Anne's dance in Escaldes-Engordany. Andorra's national holiday is Our Lady of Meritxell Day, 8 September.
Among the more important festivals and traditions are the Canólich Gathering in May, the Roser d'Ordino in July, the Meritxell Day (National Day of Andorra), the Andorra la Vella Fair, the Sant Jordi Day, the Santa Llúcia Fair, the Festivity from La Candelera to Canillo, the Carnival of Encamp, the sung of caramelles, the Festivity of Sant Esteve and the Festa del Poble.
Andorra participated regularly in the Eurovision Song Contest between 2004 and 2009, being the only participating country presenting songs in Catalan.
In popular folklore, the best-known Andorran legends are the legend of Charlemagne, according to which this Frankish King would have founded the country, the White Lady of Auvinyà, the Buner d'Ordino, the legend of Engolasters Lake and the legend of Our Lady of Meritxell.
|
Andorran gastronomy is mainly Catalan, although it has also adopted other elements of French and Italian cuisines. The cuisine of the country has similar characteristics with the neighbours of Cerdanya and Alt Urgell, with whom it has strong cultural ties. Andorra's cuisine is marked by its nature as mountain valleys. Typical dishes of the country are quince all-i-oli, duck with winter pear, roast lamb with nuts, pork civet, massegada cake, escarole with pears, duck confit and mushrooms, escudella, spinach with raisins and pine nuts, jelly marmalade, stuffed murgues (mushrooms) with pork, dandelion salad, and Andorran river trout. To drink, mulled wine and beer are also popular. Some of the dishes are very common in the mountainous regions of Catalonia, such as trinxat, embotits, cooked snails, rice with mushrooms, mountain rice and mató.
Pre-Romanesque and Romanesque art are one of the most important artistic manifestations and characteristics of the Principality. The Romanesque one allows to know the formation of the parochial communities, the relations of (social and political) power and the national culture. There are a total of forty Romanesque churches that stand out as being small austere ornamentation constructions, as well as bridges, fortresses and manor houses of the same period.

Summer solstice fire festivals in the Pyrenees was included as UNESCO Intangible cultural heritage in 2015. Also the Madriu-Perafita-Claror Valley became Andorra's first, and to date its only, UNESCO World Heritage Site in 2004, with a small extension in 2006.
Sports.
Andorra is famous for its winter sports. Andorra has the largest territory of ski slopes in the Pyrenees (3100 hectares and about 350 km of slopes) and two ski resorts. Grandvalira is the largest and most popular resort. Other popular sports played in Andorra include football, rugby union, basketball, and roller hockey.
For roller hockey, Andorra usually plays in the CERH Euro Cup and FIRS Roller Hockey World Cup. In 2011, Andorra was the host country to the 2011 European League Final Eight.
The country is represented in association football by the Andorra national football team. The team gained its first competitive win in a European Championship qualifier on 11 October 2019, against Moldova. Football is governed in Andorra by the Andorran Football Federation – founded in 1994, it organises the national competitions of association football (Primera Divisió, Copa Constitució and Supercopa) and futsal. Andorra was admitted to UEFA and FIFA in the same year, 1996. FC Andorra, a club based in Andorra la Vella founded in 1942, compete in the Spanish football league system.
|
Rugby is a traditional sport in Andorra, mainly influenced by its popularity in southern France. The Andorra national rugby union team, nicknamed Els Isards, plays on the international stage in rugby union and rugby sevens. VPC Andorra XV is a rugby team based in Andorra la Vella, which actually plays in the French championship.
Basketball's popularity has increased in the country since the 1990s, when the Andorran team BC Andorra played in the top league of Spain (Liga ACB). After 18 years the club returned to the top league in 2014.
Other sports practised in Andorra include cycling, volleyball, judo, Australian Rules football, handball, swimming, gymnastics, tennis, and motorsports. In 2012, Andorra raised its first national cricket team and played a home match against the Dutch Fellowship of Fairly Odd Places Cricket Club, the first match played in the history of Andorra at an altitude of .
Andorra first participated at the Olympic Games in 1976. The country has appeared in every Winter Olympic Games since 1976. Andorra competes in the Games of the Small States of Europe, being twice the host country, in 1991 and 2005.

As one of the Catalan Countries, Andorra is home to a team of castellers, or Catalan human tower builders. The , based in the town of Santa Coloma d'Andorra, are recognised by the , the governing body of castells.
Tourism.
Skiing, hiking, cross-country running, and cycling are all popular sports tourism activities in Andorra. Andorra's economy is heavily built on tourism.
Andorra generally enjoys a ski season from late November to early April, depending on weather conditions. Outside of the ski season, some of the ski lift facilities continue to operate at lower capacity, facilitating access to popular view points such as the Tristaina solar viewpoint, a viewpoint–sundial located on the peak of Peyreguils at an altitude of 2,701 metres and a few metres from the geographical border between Andorra and France. This peak is part of the Tristaina cirque, along with the Costa Rodona, Tristaina, Creussans, and Cabanyó peaks.

Arithmetic mean
In mathematics and statistics, the arithmetic mean ( ), arithmetic average, or just the "mean" or "average" (when the context is clear) is the sum of a collection of numbers divided by the count of numbers in the collection. The collection is often a set of results from an experiment, an observational study, or a survey. The term "arithmetic mean" is preferred in some mathematics and statistics contexts because it helps distinguish it from other types of means, such as geometric and harmonic.
In addition to mathematics and statistics, the arithmetic mean is frequently used in economics, anthropology, history, and almost every academic field to some extent. For example, per capita income is the arithmetic average income of a nation's population.
While the arithmetic mean is often used to report central tendencies, it is not a robust statistic: it is greatly influenced by outliers (values much larger or smaller than most others). For skewed distributions, such as the distribution of income for which a few people's incomes are substantially higher than most people's, the arithmetic mean may not coincide with one's notion of "middle". In that case, robust statistics, such as the median, may provide a better description of central tendency.
|
Definition.
The arithmetic mean of a set of observed data is equal to the sum of the numerical values of each observation, divided by the total number of observations. Symbolically, for a data set consisting of the values formula_1, the arithmetic mean is defined by the formula:
In simpler terms, the formula for the arithmetic mean is:
formula_3
For example, if the monthly salaries of formula_4 employees are formula_5, then the arithmetic mean is:
If the data set is a statistical population (i.e., consists of every possible observation and not just a subset of them), then the mean of that population is called the "population mean" and denoted by the Greek letter formula_7. If the data set is a statistical sample (a subset of the population), it is called the "sample mean" (which for a data set formula_8 is denoted as formula_9).
The arithmetic mean can be similarly defined for vectors in multiple dimensions, not only scalar values; this is often referred to as a centroid. More generally, because the arithmetic mean is a convex combination (meaning its coefficients sum to formula_10), it can be defined on a convex space, not only a vector space.
|
History.
The statistician Churchill Eisenhart, senior researcher fellow at the U. S. National Bureau of Standards, traced the history of the arithmetic mean in detail. In the modern age it started to be used as a way of combining various observations that should be identical, but were not such as estimates of the direction of magnetic north.
In 1635 the mathematician Henry Gellibrand described as “meane” the midpoint of a lowest and highest number, not quite the arithmetic mean. In 1668, a person known as “DB” was quoted in the Transactions of the Royal Society describing “taking the mean” of five values:
Motivating properties.
The arithmetic mean has several properties that make it interesting, especially as a measure of central tendency. These include:
Contrast with median.
The arithmetic mean may be contrasted with the median. The median is defined such that no more than half the values are larger, and no more than half are smaller than it. If elements in the data increase arithmetically when placed in some order, then the median and arithmetic average are equal. For example, consider the data sample formula_20. The mean is formula_21, as is the median. However, when we consider a sample that cannot be arranged to increase arithmetically, such as formula_22, the median and arithmetic average can differ significantly. In this case, the arithmetic average is formula_23, while the median is formula_24. The average value can vary considerably from most values in the sample and can be larger or smaller than most.
|
There are applications of this phenomenon in many fields. For example, since the 1980s, the median income in the United States has increased more slowly than the arithmetic average of income.
Generalizations.
Weighted average.
A weighted average, or weighted mean, is an average in which some data points count more heavily than others in that they are given more weight in the calculation. For example, the arithmetic mean of formula_25 and formula_26 is formula_27, or equivalently formula_28. In contrast, a "weighted" mean in which the first number receives, for example, twice as much weight as the second (perhaps because it is assumed to appear twice as often in the general population from which these numbers were sampled) would be calculated as formula_29. Here the weights, which necessarily sum to one, are formula_30 and formula_31, the former being twice the latter. The arithmetic mean (sometimes called the "unweighted average" or "equally weighted average") can be interpreted as a special case of a weighted average in which all weights are equal to the same number (formula_32 in the above example and formula_33 in a situation with formula_34 numbers being averaged).
|
Continuous probability distributions.
If a numerical property, and any sample of data from it, can take on any value from a continuous range instead of, for example, just integers, then the probability of a number falling into some range of possible values can be described by integrating a continuous probability distribution across this range, even when the naive probability for a sample number taking one certain value from infinitely many is zero. In this context, the analog of a weighted average, in which there are infinitely many possibilities for the precise value of the variable in each range, is called the "mean of the probability distribution". The most widely encountered probability distribution is called the normal distribution; it has the property that all measures of its central tendency, including not just the mean but also the median mentioned above and the mode (the three Ms), are equal. This equality does not hold for other probability distributions, as illustrated for the log-normal distribution here.
|
Angles.
Particular care is needed when using cyclic data, such as phases or angles. Taking the arithmetic mean of 1° and 359° yields a result of 180°.
This is incorrect for two reasons:
In general application, such an oversight will lead to the average value artificially moving towards the middle of the numerical range. A solution to this problem is to use the optimization formulation (that is, define the mean as the central point: the point about which one has the lowest dispersion) and redefine the difference as a modular distance (i.e., the distance on the circle: so the modular distance between 1° and 359° is 2°, not 358°).
Symbols and encoding.
The arithmetic mean is often denoted by a bar (vinculum or macron), as in formula_12.
Some software (text processors, web browsers) may not display the "x̄" symbol correctly. For example, the HTML symbol "x̄" combines two codes — the base letter "x" plus a code for the line above ( ̄ or ¯).
In some document formats (such as PDF), the symbol may be replaced by a "¢" (cent) symbol when copied to a text processor such as Microsoft Word.

American Football Conference
The American Football Conference (AFC) is one of the two conferences of the National Football League (NFL), the highest level of professional American football in the United States. The AFC and its counterpart, the National Football Conference (NFC), each have 16 teams organized into four divisions. Both conferences were created as part of the 1970 merger between the National Football League, and the American Football League (AFL). All ten of the AFL teams, and three NFL teams, became members of the new AFC, with the remaining thirteen NFL teams forming the NFC. A series of league expansions and division realignments have occurred since the merger, thus making the current total of 16 teams in each conference. The current AFC champions are the Kansas City Chiefs, who defeated the Buffalo Bills in the 2024 season's AFC Championship Game for their fifth conference championship and went on to lose Super Bowl LIX against the Philadelphia Eagles.
Teams.
Like the NFC, the conference has 16 teams organized into four divisions each with four teams: East, North, South and West.
|
Season structure.
This chart of the 2024 season standings displays an application of the NFL scheduling formula. The Chiefs in 2024 (highlighted in green) finished in first place in the AFC West. Thus, in 2025, the Chiefs will play two games against each of its division rivals (highlighted in light blue), one game against each team in the AFC South and NFC East (highlighted in yellow), and one game each against the first-place finishers in the AFC East, AFC North (highlighted in orange) and NFC North (highlighted in pink).
Currently, the fourteen opponents each team faces over the 17-game regular season schedule are set using a predetermined formula:
Each AFC team plays the other teams in their respective division twice (home and away) during the regular season, in addition to eleven other games assigned to their schedule by the NFL: three games are assigned on the basis of a particular team's final divisional standing from the previous season, and the remaining eight games are split between the roster of two other NFL divisions. This assignment shifts each year and will follow a standard cycle. Using the 2023 regular season schedule as an example, each team in the AFC West plays against every team in the AFC East and NFC North. In this way, non-divisional competition will be mostly among common opponents – the exception being the three games assigned based on the team's prior-season divisional standing.
|
At the end of each season, the four division winners and three wild cards (non-division winners with best regular season record) in the AFC qualify for the playoffs. The AFC playoffs culminate in the AFC Championship Game, with the winner receiving the Lamar Hunt Trophy. The AFC champion then plays the NFC champion in the Super Bowl.
History.
With the impending merger with the American Football League (AFL) for the 1970 NFL season, the league had careful discussion over the nature of which teams would play in the newly instituted conferences. Then-NFL President and owner of the Cleveland Browns Art Modell had suggested of a format in which three teams from the NFL would move to the AFC to create two thirteen-team conferences. But negotiations between NFL commissioner Pete Rozelle and other owners was rampant in who would move (for his part, Modell had first assumed the three most recent expansion NFL teams - Minnesota Vikings, Atlanta Falcons, New Orleans Saints would be the ones to move to the AFC), since others wanted to simply have no realignment of NFL teams. The AFL had begun play in 1960 with eight teams before adding two more expansion clubs (the Miami Dolphins in 1966 and the Cincinnati Bengals in 1968) before the merger.
|
Modell was hospitalized for internal bleeding around the time negotiations were still going. Moreover, Modell was struggling to service the debt he incurred from his purchase of the Browns. Furthermore, he realized there was an opportunity to establish a lucrative in-state rivalry with the newly-established Bengals, who had been founded by Paul Brown after Modell had forced him out of Cleveland after purchasing the team.
When Modell was visited in the hospital by Art Rooney (owner of the Pittsburgh Steelers) and Wellington Mara (owner of the New York Giants), Modell offered to have his franchise move to the AFC, provided two other "old guard" franchises did so as well and the three affected teams to move were adequately compensated for joining what was still looked down on in NFL circles as a "junior" or "inferior" circuit. Not wanting to lose his long-established rivalry with Cleveland, the equally cash-strapped Rooney quickly agreed to join the Browns in the AFC. The other NFL owner to ultimately agree to move was the Baltimore Colts' Carroll Rosenbloom.
|
Thus, in order to equalize the number of teams in each conference, three NFL teams that predated the AFL's launch (the Cleveland Browns, Pittsburgh Steelers, and the then-Baltimore Colts) joined the ten former AFL teams to form the AFC in exchange for $3 million each in indemnities, with the announcement coming on May 10, 1969. The two AFL divisions AFL East and AFL West were more or less intact, while the NFL's Century Division, in which the Browns and the Steelers had played since 1967, was moved from the NFL to become the new AFC Central. Upon the completion of the merger of the AFL and NFL in 1970, the newly minted American Football Conference had already agreed upon their divisional setup along mostly geographical lines for the 1970 season; the National Football Conference, however, could not agree upon their setup, and one was chosen from a fishbowl on January 16, 1970.
Since the merger, five expansion teams have joined the AFC and two have left, thus making the current total 16. When the Seattle Seahawks and the Tampa Bay Buccaneers joined the league in 1976, they were temporarily placed in the NFC and AFC respectively. This arrangement lasted for one season only before the two teams switched conferences. The Seahawks eventually returned to the NFC as a result of the 2002 realignment. The expansion Jacksonville Jaguars joined the AFC in 1995. There have been five teams that have relocated at least once. In 1984, the Baltimore Colts relocated to Indianapolis. In 1995, the Cleveland Browns had attempted to move to Baltimore; the resulting dispute between Cleveland and the team led to Modell establishing the Baltimore Ravens with the players and personnel from the Browns, while the Browns were placed in suspended operations before they were reinstated by the NFL. The Ravens were treated as an expansion team.
|
In California, the Oakland Raiders relocated to Los Angeles in 1982, back to Oakland in 1995, and then to Las Vegas in 2020, while the San Diego Chargers returned to Los Angeles in 2017 after 56 years in San Diego.
The Houston Oilers moved to Tennessee in 1997, where they were renamed the Tennessee Oilers. The team would change its name again, two years later, to the Tennessee Titans.
The NFL would again expand in 2002, adding the Houston Texans to the AFC. With the exception of the aforementioned relocations since that time, the divisional setup has remained static ever since.
Between 1995 and 2022, the AFC has sent only 9 of its 16 teams to the Super Bowl: New England Patriots (10 times), Pittsburgh Steelers (4 times), Denver Broncos (4 times), Baltimore Ravens (2 times), Indianapolis Colts (2 times), Kansas City Chiefs (3 times), Cincinnati Bengals (1 time), Las Vegas Raiders (1 time), Tennessee Titans (1 time). By contrast, the NFC has sent 13 of the 16 NFC teams during that same time frame with only the Detroit Lions, Minnesota Vikings, and Washington Commanders missing out on an appearance in the Super Bowl. 17 of the 19 AFC champions from 2001 to 2019 have started one of just three quarterbacks - Tom Brady, Peyton Manning and Ben Roethlisberger - in the Super Bowl. The AFC has started 7 quarterbacks in the last 20 Super Bowls, while the NFC has started 16.

Logo.
The original AFC logo was very similar to the AFL logo, however the merged league quickly created an updated logo for the AFC that, while preserving the basic elements of the old AFL logo, used a much bolder red "A" and six similarly bold red stars surrounding it, in contrast to the six blue AFL stars. The league also created a logo for the NFC in 1970, which like the AFL and AFC logos also contained only the first letter as opposed to a full abbreviation, but with only three stars (to represent the then-three divisions of the Conference). The AFC logo basically remained unchanged from 1970 to 2009. The 2010 NFL season introduced an updated AFC logo, with the most notable revision being the removal of two stars (leaving four representing the four divisions of the AFC), and moving the stars inside the letter, similar to the NFC logo, which itself was updated at the same time to add a fourth star.
Notably, the Kansas City Chiefs (still owned by the descendants of AFL founder Lamar Hunt) continue to regularly feature the original AFL logo on their jerseys as of .

Television.
NBC aired the AFC's Sunday afternoon and playoff games from 1970 through the 1997 season. From 1998 to 2013, CBS was the primary broadcast rightsholder to the AFC; in those years, all interconference games in which the AFC team was the visiting team were broadcast on either NBC or CBS. Since 2014, the cross-flex policy allows select AFC games (that involve them playing an NFC team at home or intraconference games) to be moved from CBS to Fox. Since 1990, select AFC playoff games have been seen on ABC or ESPN.

Animal Farm
Animal Farm is a satirical allegorical novella, in the form of a beast fable, by George Orwell, first published in England on 17 August 1945. It tells the story of a group of anthropomorphic farm animals who rebel against their human farmer, hoping to create a society where the animals can be equal, free, and happy. Ultimately, the rebellion is betrayed, and under the dictatorship of a pig named Napoleon, the farm ends up in a far worse state than before.
According to Orwell, "Animal Farm" reflects events leading up to the Russian Revolution of 1917 and then on into the Stalinist era of the Soviet Union, a period when Russia lived under the Marxist–Leninist ideology of Joseph Stalin. Orwell, a democratic socialist, was a critic of Stalin and hostile to Moscow-directed Stalinism, an attitude that was critically shaped by his experiences during the Barcelona May Days conflicts between the POUM and Stalinist forces, during the Spanish Civil War. In a letter to Yvonne Davet, Orwell described "Animal Farm" as a satirical tale against Stalin (""), and in his essay, "Why I Write" (1946), wrote: ""Animal Farm" was the first book in which I tried, with full consciousness of what I was doing, to fuse political purpose and artistic purpose into one whole".
|
The original title of the novel was Animal Farm: A Fairy Story. American publishers dropped the subtitle when it was published in 1946, and only one of the translations, during Orwell's lifetime, the Telugu version, kept it. Other title variations include subtitles like "A Satire" and "A Contemporary Satire". Orwell suggested the title ' for the French translation, which abbreviates to URSA, the Latin word for "bear", a symbol of Russia. It also played on the French name of the Soviet Union, '.
Orwell wrote the book between November 1943 and February 1944, when the United Kingdom was in its wartime alliance with the Soviet Union against Nazi Germany and the British intelligentsia held Stalin in high esteem, which Orwell hated. The manuscript was initially rejected by several British and American publishers, including one of Orwell's own, Victor Gollancz, which delayed its publication. It became a great commercial success when it did appear, as international relations and public opinion were transformed as the wartime alliance gave way to the Cold War.
|
"Time" magazine chose the book as one of the 100 best English-language novels (1923 to 2005); it also featured at number 31 on the Modern Library List of Best 20th-Century Novels, and number 46 on the BBC's The Big Read poll. It won a Retrospective Hugo Award in 1996, and is included in the Great Books of the Western World selection.
Plot summary.
The animal populace of the poorly run Manor Farm near Willingdon, England, is ripened for rebellion by neglect at the hands of the irresponsible and alcoholic farmer Mr. Jones. One night, the exalted boar Old Major holds a conference, at which he calls for the overthrow of humans and teaches the animals a revolutionary song called "Beasts of England". When Old Major dies, two young pigs, Snowball and Napoleon, assume command and stage a revolt, driving Mr. Jones off the farm and renaming the property "Animal Farm". They adopt the Seven Commandments of Animalism, the most important of which is, "All animals are equal". The decree is painted in large letters on one side of the barn. Snowball teaches the animals to read and write, while Napoleon educates young puppies on the principles of Animalism. To commemorate the start of Animal Farm, Snowball raises a green flag with a white hoof and horn. Food is plentiful, and the farm runs smoothly. The pigs elevate themselves to positions of leadership and set aside special food items, ostensibly for their health. Following an unsuccessful attempt by Mr. Jones and his associates to retake the farm (later dubbed the "Battle of the Cowshed"), Snowball announces his plans to modernise the farm by building a windmill. Napoleon disputes this idea, and matters come to a head, which culminates in Napoleon's dogs chasing Snowball away and Napoleon effectively declaring himself supreme commander.
|
Napoleon enacts changes to the governance structure of the farm, replacing meetings with a committee of pigs who will run the farm. Through a young porker named Squealer, Napoleon claims credit for the idea of building the windmill, claiming that Snowball was only trying to win animals to his side. The animals work harder with the promise of easier lives with the windmill. When the animals find the windmill collapsed after a violent storm, Napoleon and Squealer persuade the animals that Snowball is trying to sabotage their project, and begin to purge the farm of animals accused by Napoleon of consorting with his old rival. When some animals recall the Battle of the Cowshed, Napoleon (who was nowhere to be found during the battle) gradually smears Snowball to the point of saying he is a collaborator of Mr. Jones, even dismissing the fact that Snowball was given an award of courage, while falsely representing himself as the main hero of the battle. "Beasts of England" is replaced with "Animal Farm", while an anthem glorifying Napoleon, who is presumably adopting the lifestyle of a man ("Comrade Napoleon"), is composed and sung. Napoleon then conducts a second purge, during which many animals who are alleged to be helping Snowball in plots are executed by Napoleon's dogs, which troubles the rest of the animals. Despite their hardships, the animals are easily pacified by Napoleon's retort that they are better off than they were under Mr. Jones, as well as by the sheep's continual bleating of "four legs good, two legs bad".
|
Mr. Frederick, a neighbouring farmer, attacks the farm, using blasting powder to blow up the restored windmill. Although the animals win the battle, they do so at great cost, as many, including Boxer the workhorse, are wounded. Although he recovers from this, Boxer eventually collapses while working on the windmill (being almost 12 years old at that point). He is taken away in a knacker's van and a donkey called Benjamin alerts the animals of this, but Squealer quickly waves off their alarm by persuading the animals that the van had been purchased from the knacker by an animal hospital and that the previous owner's signboard had not been repainted. Squealer subsequently reports Boxer's death and honours him with a festival the following day. In truth, Napoleon had engineered the sale of Boxer to the knacker, allowing him and his inner circle to acquire money to buy whisky for themselves.
Years pass, the windmill is rebuilt and another windmill is constructed, which makes the farm a good amount of income. However, the ideals that Snowball discussed, including stalls with electric lighting, heating, and running water, are forgotten, with Napoleon advocating that the happiest animals live simple lives. Snowball has been forgotten, alongside Boxer, with "the exception of the few who knew him". Many of the animals who participated in the rebellion are dead or old. Mr. Jones is also now known to be dead, having "died in an inebriates' home in another part of the country". The pigs start to resemble humans, as they walk upright, carry whips, drink alcohol, and wear clothes. The Seven Commandments are abridged to just one phrase: "All animals are equal, but some animals are more equal than others". The maxim "Four legs good, two legs bad" is similarly changed to "Four legs good, two legs better". Other changes include the Hoof and Horn flag being replaced with a plain green banner and Old Major's skull, which was previously put on display, being reburied.
|
Napoleon holds a dinner party for the pigs and local farmers, with whom he celebrates a new alliance. The other farm animals, who have not been invited, gather toward the window to watch. He abolishes the practice of the revolutionary traditions and restores the name "The Manor Farm". The men and pigs start playing cards, flattering and praising each other while cheating at the game. Both Napoleon and Mr. Pilkington, one of the farmers, play the ace of spades at the same time and both sides begin fighting loudly over who cheated first. When the animals outside look at the pigs and men, they can no longer distinguish between the two.
Genre and style.
George Orwell's "Animal Farm" is an example of a political satire and an allegory that was intended to have a "wider application", according to Orwell himself, in terms of its relevance. Stylistically, the work shares many similarities with some of Orwell's other works, most notably "Nineteen Eighty-Four", as both have been considered works of Swiftian satire. Furthermore, these two prominent works seem to suggest Orwell's bleak view of the future for humanity; he seems to stress the potential/current threat of dystopias similar to those in "Animal Farm" and "Nineteen Eighty-Four". In these kinds of works, Orwell distinctly references the disarray and traumatic conditions of Europe following the Second World War. Orwell's style and writing philosophy as a whole were very concerned with the pursuit of truth in writing.
|
Orwell was committed to communicating straightforwardly, given the way that he felt words were commonly used in politics to deceive and confuse. For this reason, he is careful, in "Animal Farm", to make sure the narrator speaks in an unbiased and uncomplicated fashion. The difference is seen in the way that the animals speak and interact, as the general moral animals seem to speak their minds clearly, while the wicked animals on the farm, such as Napoleon, twist language in such a way that it meets their insidious desires. This style reflects Orwell's proximity to the issues facing Europe at the time and his determination to comment critically on Stalin's Soviet Russia.
Background.
Origin and writing.
Just as "Nineteen Eighty-Four" would be inspired by Yevgeny Zamyatin's "We", "Animal Farm" also had its influences: "In 1937, the year in which Orwell said he first thought of "Animal Farm", Gollancz's Left Book Club published both "The Road to Wigan Pier" and a left-wing children's book, "The Adventures of the Little Pig and Other Stories" by F. Le Gros and Ida Clark."
|
George Orwell wrote the manuscript between November 1943 and February 1944 after his experiences during the Spanish Civil War, which he described in "Homage to Catalonia" (1938). In the preface of a 1947 Ukrainian edition of "Animal Farm", he explained how escaping the communist purges in Spain taught him "how easily totalitarian propaganda can control the opinion of enlightened people in democratic countries". This motivated Orwell to expose and strongly condemn what he saw as the Stalinist corruption of the original socialist ideals. "Homage to Catalonia" sold poorly; after seeing Arthur Koestler's best-selling "Darkness at Noon" about the Moscow Trials, Orwell decided that fiction would be the best way to describe totalitarianism.
Immediately before writing the book, Orwell quit the BBC. He was also upset about a booklet for propagandists the Ministry of Information had put out. The booklet included instructions on how to quell ideological fears of the Soviet Union, such as directions to claim that the Red Terror was a figment of Nazi imagination.
|
In the preface, Orwell described the source of the idea of setting the book on a farm:
In 1944, the manuscript was almost lost when a German V-1 flying bomb destroyed his London home. Orwell spent hours sifting through the rubble to find the pages intact.
Publication.
Publishing.
Orwell initially encountered difficulty getting the manuscript published, largely due to fears that the book might upset the alliance between Britain, the United States, and the Soviet Union. Four publishers refused to publish "Animal Farm", yet one had initially accepted the work but declined it after consulting the Ministry of Information. Eventually, Secker and Warburg published the first edition in 1945.
During World War II, it became clear to Orwell that anti-Soviet literature was not something which most major publishing houses would touch – including his regular publisher Gollancz. He also submitted the manuscript to Faber and Faber, where the poet T. S. Eliot (who was a director of the firm) rejected it; Eliot wrote back to Orwell praising the book's "good writing" and "fundamental integrity", but declared that they would only accept it for publication if they had some sympathy for the viewpoint "which I take to be generally Trotskyite". Eliot said he found the view "not convincing", and contended that the pigs were made out to be the best to run the farm; he posited that someone might argue "what was needed ... was not more communism but more public-spirited pigs". Orwell let André Deutsch, who was working for Nicholson & Watson in 1944, read the typescript, and Deutsch was convinced that Nicholson & Watson would want to publish it; however, they did not, and "lectured Orwell on what they perceived to be errors in "Animal Farm"". In his "London Letter" on 17 April 1944 for "Partisan Review", Orwell wrote that it was "now next door to impossible to get anything overtly anti-Russian printed. Anti-Russian books do appear, but mostly from Catholic publishing firms and always from a religious or frankly reactionary angle".
|
The publisher Jonathan Cape, who had initially accepted "Animal Farm", subsequently rejected the book after an official at the British Ministry of Information warned him off – although the civil servant who it is assumed gave the order was later found to be a Soviet spy. Writing to Leonard Moore, a partner in the literary agency of Christy & Moore, publisher Jonathan Cape explained that the decision had been taken on the advice of a senior official in the Ministry of Information. Such flagrant anti-Soviet bias was unacceptable, and the choice of pigs as the dominant class was thought to be especially offensive. It may reasonably be assumed that the "important official" was a man named Peter Smollett, who was later unmasked as a Soviet agent. Orwell was suspicious of Smollett/Smolka, and he would be one of the names Orwell included in his list of Crypto-Communists and Fellow-Travellers sent to the Information Research Department in 1949. The publisher wrote to Orwell, saying:
Frederic Warburg also faced pressures against publication, even from people in his own office and from his wife Pamela, who felt that it was not the moment for ingratitude towards Stalin and the Red Army, which had played a major part in defeating Adolf Hitler. A Russian translation was printed in the paper "Posev", and in permitting a Russian translation of "Animal Farm", Orwell refused in advance all royalties. A translation in Ukrainian, which was produced in Germany, was confiscated in large part by the American wartime authorities and handed over to the Soviet repatriation commission.
|
In October 1945, Orwell wrote to Frederic Warburg expressing interest in pursuing the possibility that the political cartoonist David Low might illustrate "Animal Farm". Low had written a letter saying that he had had "a good time with "Animal Farm" – an excellent bit of satire – it would illustrate perfectly". Nothing came of this, and a trial issue produced by Secker & Warburg in 1956 illustrated by John Driver was abandoned. The Folio Society published an edition in 1984 illustrated by Quentin Blake and an edition illustrated by the cartoonist Ralph Steadman was published by Secker & Warburg in 1995 to celebrate the fiftieth anniversary of the first edition of "Animal Farm".
Preface.
Orwell originally wrote a preface complaining about British self-censorship and how the British people were suppressing criticism of the USSR, their World War II ally:
Although the first edition allowed space for the preface in the author's proof, it was not included, and the page numbers had to be renumbered at the last minute. As of June 2009, most editions of the book have not included it.
|
In 1972, Ian Angus found the original typescript titled "The Freedom of the Press", and Bernard Crick published it, together with his introduction, in "The Times Literary Supplement" on 15 September 1972 as "How the essay came to be written". Orwell's essay criticised British self-censorship by the press, specifically the suppression of unflattering descriptions of Stalin and the Soviet government. The same essay also appeared in the Italian 1976 edition of "Animal Farm" with another introduction by Crick, claiming to be the first edition with the preface. Other publishers were still declining to publish it.
Reception.
Contemporary reviews of the work were not universally positive. Writing in the American "New Republic" magazine, George Soule expressed his disappointment in the book, writing that it "puzzled and saddened me. It seemed on the whole dull. The allegory turned out to be a creaking machine for saying in a clumsy way things that have been said better directly". Soule believed that the animals were not consistent enough with their real-world inspirations, and said, "It seems to me that the failure of this book (commercially it is already assured of tremendous success) arises from the fact that the satire deals not with something the author has experienced, but rather with stereotyped ideas about a country which he probably does not know very well".
|
"The Guardian" on 24 August 1945 called "Animal Farm" "a delightfully humorous and caustic satire on the rule of the many by the few". Tosco Fyvel, writing in "Tribune" on the same day, called the book "a gentle satire on a certain State and on the illusions of an age which may already be behind us". Julian Symons responded, on 7 September, "Should we not expect, in "Tribune" at least, acknowledgement of the fact that it is a satire not at all gentle upon a particular State – Soviet Russia? It seems to me that a reviewer should have the courage to identify Napoleon with Stalin, and Snowball with Trotsky, and express an opinion favourable or unfavourable to the author, upon a political ground. In a hundred years perhaps, "Animal Farm" may be simply a fairy story; today it is a political satire with a good deal of point". "Animal Farm" has been subject to much comment in the decades since these early remarks.
Between 1952 and 1957, the CIA, in an operation codenamed Aedinosaur, sent millions of balloons carrying copies of the novel into Poland, Hungary and Czechoslovakia, whose air forces tried to shoot the balloons down. The Information Research Department, a secret Cold War propaganda agency of the British government, translated the book into various languages such as Arabic.

"Time" magazine chose "Animal Farm" as one of the 100 best English-language novels (1923 to 2005); it also featured at number 31 on the Modern Library List of Best 20th-Century Novels. It won a Retrospective Hugo Award in 1996 and is included in the Great Books of the Western World selection.
Popular reading in schools, "Animal Farm" was ranked the UK's favourite book from school in a 2016 poll.
"Animal Farm" has also faced an array of challenges in school settings around the US. The following are examples of this controversy that has existed around Orwell's work:
"Animal Farm" has also faced similar forms of resistance in other countries. The ALA also mentions the way that the book was prevented from being featured at the International Book Fair in Moscow, Russia, in 1977 and banned from schools in the United Arab Emirates for references to practices or actions that defy Arab or Islamic beliefs, such as pigs or alcohol.
In the same manner, "Animal Farm" has also faced relatively recent issues in China. In 2018, the Chinese government decided to censor all online posts about or referring to "Animal Farm". However, the book itself, as of 2019, remains sold in stores. Amy Hawkins and Jeffrey Wasserstrom of "The Atlantic" stated in 2019 that the book is widely available in mainland China for several reasons: censors believe the general public is unlikely to read a highbrow book, because the elites who do read books feel connected to the ruling party anyway, and because the Communist Party sees being too aggressive in blocking cultural products as a liability. The authors stated: "It was – and remains – as easy to buy "1984" and "Animal Farm" in Shenzhen or Shanghai as it is in London or Los Angeles". An enhanced version of the book, launched in India in 2017, was widely praised for capturing the author's intent, by republishing the proposed preface of the First Edition and the preface he wrote for the Ukrainian edition.

Analysis.
Animalism.
Snowball, Napoleon, and Squealer adapt Old Major's ideas into "a complete system of thought", which they formally name Animalism, an allegoric reference to Communism, not to be confused with the philosophy of Animalism. Soon after, Napoleon and Squealer partake in activities associated with the humans (drinking alcohol, sleeping in beds, trading), which were explicitly prohibited by the Seven Commandments. Squealer is employed to alter the Seven Commandments to account for this humanisation, an allusion to the Soviet government's revising of history to exercise control of the people's beliefs about themselves and their society.
The original commandments are:
These commandments are also distilled into the maxim "Four legs good, two legs bad!" which is primarily used by the sheep on the farm, often to disrupt discussions and disagreements between animals on the nature of Animalism.
Later, Napoleon and his pigs secretly revise some commandments to clear themselves of accusations of law-breaking. The changed commandments are as follows, with the changes bolded:
|
Eventually, these are replaced with the maxims, "All animals are equal, but some animals are more equal than others", and "Four legs good, two legs better" as the pigs become more anthropomorphic. This is an ironic twist to the original purpose of the Seven Commandments, which was supposed to keep order within Animal Farm by uniting the animals together against the humans and preventing animals from following the humans' evil habits. Through the revision of the commandments, Orwell demonstrates how simply political dogma can be turned into malleable propaganda.
Significance and allegory.
Orwell biographer Jeffrey Meyers has written, "virtually every detail has political significance in this allegory". Orwell himself wrote in 1946, "Of course I intended it primarily as a satire on the Russian revolution ... [and] "that kind" of revolution (violent conspiratorial revolution, led by unconsciously power-hungry people) can only lead to a change of masters [–] revolutions only effect a radical improvement when the masses are alert". In a preface for a 1947 Ukrainian edition, he stated, "for the past ten years I have been convinced that the destruction of the Soviet myth was essential if we wanted a revival of the socialist movement. On my return from Spain [in 1937] I thought of exposing the Soviet myth in a story that could be easily understood by almost anyone and which could be easily translated into other languages".
|
The revolt of the animals against Farmer Jones is Orwell's analogy with the October 1917 Bolshevik Revolution. The "Battle of the Cowshed" has been said to represent the allied invasion of Soviet Russia in 1918, and the defeat of the White Russians in the Russian Civil War. The pigs' rise to preeminence mirrors the rise of a Stalinist bureaucracy in the USSR, just as Napoleon's emergence as the farm's sole leader reflects Stalin's emergence. The pigs' appropriation of milk and apples for their own use, "the turning point of the story" as Orwell termed it in a letter to Dwight Macdonald, stands as an analogy for the crushing of the left-wing 1921 Kronstadt revolt against the Bolsheviks, and the difficult efforts of the animals to build the windmill suggest the various five-year plans. The puppies controlled by Napoleon parallel the nurture of the secret police in the Stalinist structure, and the pigs' treatment of the other animals on the farm recalls the internal terror faced by the populace in the 1930s. In chapter seven, when the animals confess their non-existent crimes and are killed, Orwell directly alludes to the purges, confessions and show trials of the late 1930s. These contributed to Orwell's conviction that the Bolshevik revolution had been corrupted and the Soviet system become rotten.
|
Peter Edgerly Firchow and Peter Davison contend that the "Battle of the Windmill", specifically referencing the Battle of Stalingrad and the Battle of Moscow, represents World War II. During the battle, Orwell first wrote, "All the animals, including Napoleon" took cover. Orwell had the publisher alter this to "All the animals except Napoleon" in recognition of Stalin's decision to remain in Moscow during the German advance. Orwell requested the change after he met Józef Czapski in Paris in March 1945. Czapski, a survivor of the Katyn Massacre and an opponent of the Soviet regime, told Orwell, as Orwell wrote to Arthur Koestler, that it had been "the character [and] greatness of Stalin" that saved Russia from the German invasion.
Other connections that writers have suggested illustrate Orwell's telescoping of Russian history from 1917 to 1943, including the wave of rebelliousness that ran through the countryside after the Rebellion, which stands for the abortive revolutions in Hungary and Germany (Ch. IV); the conflict between Napoleon and Snowball (Ch. V), parallelling "the two rival and quasi-Messianic beliefs that seemed pitted against one another: Trotskyism, with its faith in the revolutionary vocation of the proletariat of the West; and Stalinism with its glorification of Russia's socialist destiny"; Napoleon's dealings with Whymper and the Willingdon markets (Ch. VI), paralleling the Treaty of Rapallo; and Frederick's forged bank notes, parallelling the Molotov–Ribbentrop Pact of August 1939, after which Frederick attacks Animal Farm without warning and destroys the windmill.
|
The book's close, with the pigs and men in a kind of rapprochement, reflected Orwell's view of the 1943 Tehran Conference that seemed to display the establishment of "the best possible relations between the USSR and the West" – but in reality were destined, as Orwell presciently predicted, to continue to unravel. The disagreement between the allies and the start of the Cold War is suggested when Napoleon and Pilkington, both suspicious, each "played an ace of spades simultaneously".
Similarly, the music in the novel, starting with "Beasts of England" and the later anthems, parallels "The Internationale" and its adoption and repudiation by the Soviet authorities as the anthem of the USSR in the 1920s and 1930s.
According to Masha Gessen, the metamorphosis of the eighth commandment ("some animals are more equal") was likely inspired by similar change of a party line which declared all Soviet people equal: the Russian nation and language suddenly became "first among equals" in official CPSU publications in 1936–1937.

Adaptations.
Stage productions.
A theatrical version, with music by Richard Peaslee and lyrics by Adrian Mitchell, was staged at the National Theatre London on 25 April 1984, directed by Peter Hall. It toured nine cities in 1985.
A solo version, adapted and performed by Guy Masterson, premiered at the Traverse Theatre Edinburgh in January 1995 and has toured worldwide since.
In 2021, during pandemic restrictions, the National Youth Theatre toured a stage version of "Animal Farm;" this run included outdoor performances on a farm at Soulton Hall.
A new adaptation written and directed by Robert Icke, designed by Bunny Christie with puppetry designed and directed by Toby Olié opened at the Birmingham Repertory Theatre in January 2022 before touring the UK.
The Russian composer Alexander Raskatov has written an opera based on the book. Its premiere took place on 4 March 2023 in Amsterdam as part of Dutch National Opera's 2022/2023 season.
Films.
"Animal Farm" has been adapted to film twice. Both differ from the novel and have been accused of taking significant liberties, including sanitising some aspects.
|
Andy Serkis is directing an upcoming animated film adaptation.
Radio dramatisations.
A BBC radio version, produced by Rayner Heppenstall, was broadcast in January 1947. Orwell listened to the production at his home in Canonbury Square, London, with Hugh Gordon Porteous, amongst others. Orwell later wrote to Heppenstall that Porteous, "who had not read the book, grasped what was happening after a few minutes".
A further radio production, again using Orwell's dramatisation of the book, was broadcast in January 2013 on BBC Radio 4. Tamsin Greig narrated, and the cast included Nicky Henson as Napoleon, Toby Jones as the propagandist Squealer, and Ralph Ineson as Boxer.
Comic strip.
In 1950, Norman Pett and his writing partner Don Freeman were secretly hired by the Information Research Department, a secret department of the Foreign Office, to adapt "Animal Farm" into a comic strip. This comic was not published in the United Kingdom but ran in Brazilian and Burmese newspapers.
Video game.
Developers Nerial and The Dairymen released a game based on the book in December 2020, entitled "Orwell's Animal Farm", for Windows, macOS, iOS and Android in coordination with the Orwell Estate.

Amphibian
Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant (living) amphibians belong to the monophyletic subclass Lissamphibia, with three living orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their life cycle typically starts out as aquatic larvae with gills known as tadpoles, but some species have developed behavioural adaptations to bypass this.
Young amphibians generally undergo metamorphosis from an aquatic larval form with gills to an air-breathing adult form with lungs. Amphibians use their skin as a secondary respiratory interface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards, but unlike reptiles and other amniotes, require access to water bodies to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators to habitat conditions; in recent decades there has been a dramatic decline in amphibian populations for many species around the globe.
|
The earliest amphibians evolved in the Devonian period from tetrapodomorph sarcopterygians (lobe-finned fish with articulated limb-like fins) that evolved primitive lungs, which were helpful in adapting to dry land. They diversified and became ecologically dominant during the Carboniferous and Permian periods, but were later displaced in terrestrial environments by early reptiles and basal synapsids (predecessors of mammals). The origin of modern lissamphibians, which first appeared during the Early Triassic, around 250 million years ago, has long been contentious. The most popular hypothesis is that they likely originated from temnospondyls, the most diverse group of prehistoric amphibians, during the Permian period. Another hypothesis is that they emerged from lepospondyls. A fourth group of lissamphibians, the Albanerpetontidae, became extinct around 2 million years ago.
The number of known amphibian species is approximately 8,000, of which nearly 90% are frogs. The smallest amphibian (and vertebrate) in the world is a frog from New Guinea ("Paedophryne amauensis") with a length of just . The largest living amphibian is the South China giant salamander ("Andrias sligoi"), but this is dwarfed by prehistoric temnospondyls such as "Mastodonsaurus" which could reach up to in length. The study of amphibians is called batrachology, while the study of both reptiles and amphibians is called herpetology.
|
Classification.
The word "amphibian" is derived from the Ancient Greek term (), which means 'both kinds of life', meaning 'of both kinds' and meaning 'life'. The term was initially used as a general adjective for animals that could live on land or in water, including seals and otters. Traditionally, the class Amphibia includes all tetrapod vertebrates that are not amniotes. Amphibia in its widest sense () was divided into three subclasses, two of which are extinct:
These three subclasses do not include all extinct amphibians. Other extinct amphibian groups include Embolomeri (Late Paleozoic large aquatic predators), Seymouriamorpha (semiaquatic to terrestrial Permian forms related to amniotes), among others. Names such as Tetrapoda and Stegocephalia encompass the entirety of amphibian-grade tetrapods, while Reptiliomorpha or Anthracosauria are variably used to describe extinct amphibians more closely related to amniotes than to lissamphibians.
The actual number of species in each group depends on the taxonomic classification followed. The two most common systems are the classification adopted by the website AmphibiaWeb, University of California, Berkeley, and the classification by herpetologist Darrel Frost and the American Museum of Natural History, available as the online reference database "Amphibian Species of the World". The numbers of species cited above follows Frost and the total number of known (living) amphibian species as of March 31, 2019, is exactly 8,000, of which nearly 90% are frogs.

With the phylogenetic classification, the taxon Labyrinthodontia has been discarded as it is a polyparaphyletic group without unique defining features apart from shared primitive characteristics. Classification varies according to the preferred phylogeny of the author and whether they use a stem-based or a node-based classification. Traditionally, amphibians as a class are defined as all tetrapods with a larval stage, while the group that includes the common ancestors of all living amphibians (frogs, salamanders and caecilians) and all their descendants is called Lissamphibia. The phylogeny of Paleozoic amphibians is uncertain, and Lissamphibia may possibly fall within extinct groups, like the Temnospondyli (traditionally placed in the subclass Labyrinthodontia) or the Lepospondyli, and in some analyses even in the amniotes. This means that advocates of phylogenetic nomenclature have removed a large number of basal Devonian and Carboniferous amphibian-type tetrapod groups that were formerly placed in Amphibia in Linnaean taxonomy, and included them elsewhere under cladistic taxonomy. If the common ancestor of amphibians and amniotes is included in Amphibia, it becomes a paraphyletic group.
|
All modern amphibians are included in the subclass Lissamphibia, which is usually considered a clade, a group of species that have evolved from a common ancestor. The three modern orders are Anura (the frogs), Caudata (or Urodela, the salamanders), and Gymnophiona (or Apoda, the caecilians). It has been suggested that salamanders arose separately from a temnospondyl-like ancestor, and even that caecilians are the sister group of the advanced reptiliomorph amphibians, and thus of amniotes. Although the fossils of several older proto-frogs with primitive characteristics are known, the oldest "true frog", with hopping adaptations is "Prosalirus bitis", from the Early Jurassic Kayenta Formation of Arizona. It is anatomically very similar to modern frogs. The oldest known caecilians are "Funcusvermis gilmorei" (from the Late Triassic) and "Eocaecilia micropodia" (from the Early Jurassic), both from Arizona. The earliest salamander is "Beiyanerpeton jianpingensis" from the Late Jurassic of northeastern China.
Authorities disagree as to whether Salientia is a superorder that includes the order Anura, or whether Anura is a sub-order of the order Salientia. The Lissamphibia are traditionally divided into three orders, but an extinct salamander-like family, the Albanerpetontidae, is now considered part of Lissamphibia alongside the superorder Salientia. Furthermore, Salientia includes all three recent orders plus the Triassic proto-frog, "Triadobatrachus".

Evolutionary history.
The first major groups of amphibians developed in the Devonian period, around 370 million years ago, from lobe-finned fish which were similar to the modern coelacanth and lungfish. These ancient lobe-finned fish had evolved multi-jointed leg-like fins with digits that enabled them to crawl along the sea bottom. Some fish had developed primitive lungs that help them breathe air when the stagnant pools of the Devonian swamps were low in oxygen. They could also use their strong fins to hoist themselves out of the water and onto dry land if circumstances so required. Eventually, their bony fins would evolve into limbs and they would become the ancestors to all tetrapods, including modern amphibians, reptiles, birds, and mammals. Despite being able to crawl on land, many of these prehistoric tetrapodomorph fish still spent most of their time in the water. They had started to develop lungs, but still breathed predominantly with gills.
Many examples of species showing transitional features have been discovered. "Ichthyostega" was one of the first primitive amphibians, with nostrils and more efficient lungs. It had four sturdy limbs, a neck, a tail with fins and a skull very similar to that of the lobe-finned fish, "Eusthenopteron". Amphibians evolved adaptations that allowed them to stay out of the water for longer periods. Their lungs improved and their skeletons became heavier and stronger, better able to support the weight of their bodies on land. They developed "hands" and "feet" with five or more digits; the skin became more capable of retaining body fluids and resisting desiccation. The fish's hyomandibula bone in the hyoid region behind the gills diminished in size and became the stapes of the amphibian ear, an adaptation necessary for hearing on dry land. An affinity between the amphibians and the teleost fish is the multi-folded structure of the teeth and the paired supra-occipital bones at the back of the head, neither of these features being found elsewhere in the animal kingdom.
|
At the end of the Devonian period (360 million years ago), the seas, rivers and lakes were teeming with life while the land was the realm of early plants and devoid of vertebrates, though some, such as "Ichthyostega", may have sometimes hauled themselves out of the water. It is thought they may have propelled themselves with their forelimbs, dragging their hindquarters in a similar manner to that used by the elephant seal. In the early Carboniferous (360 to 323 million years ago), the climate was relatively wet and warm. Extensive swamps developed with mosses, ferns, horsetails and calamites. Air-breathing arthropods evolved and invaded the land where they provided food for the carnivorous amphibians that began to adapt to the terrestrial environment. There were no other tetrapods on the land and the amphibians were at the top of the food chain, with some occupying ecological positions currently held by crocodiles. Though equipped with limbs and the ability to breathe air, most still had a long tapering body and strong tail. Others were the top land predators, sometimes reaching several metres in length, preying on the large insects of the period and the many types of fish in the water. They still needed to return to water to lay their shell-less eggs, and even most modern amphibians have a fully aquatic larval stage with gills like their fish ancestors. It was the development of the amniotic egg, which prevents the developing embryo from drying out, that enabled the reptiles to reproduce on land and which led to their dominance in the period that followed.
|
After the Carboniferous rainforest collapse amphibian dominance gave way to reptiles, and amphibians were further devastated by the Permian–Triassic extinction event. During the Triassic Period (252 to 201 million years ago), the reptiles continued to out-compete the amphibians, leading to a reduction in both the amphibians' size and their importance in the biosphere. According to the fossil record, Lissamphibia, which includes all modern amphibians and is the only surviving lineage, may have branched off from the extinct groups Temnospondyli and Lepospondyli at some period between the Late Carboniferous and the Early Triassic. The relative scarcity of fossil evidence precludes precise dating, but the most recent molecular study, based on multilocus sequence typing, suggests a Late Carboniferous/Early Permian origin for extant amphibians.

As they evolved from lunged fish, amphibians had to make certain adaptations for living on land, including the need to develop new means of locomotion. In the water, the sideways thrusts of their tails had propelled them forward, but on land, quite different mechanisms were required. Their vertebral columns, limbs, limb girdles and musculature needed to be strong enough to raise them off the ground for locomotion and feeding. Terrestrial adults discarded their lateral line systems and adapted their sensory systems to receive stimuli via the medium of the air. They needed to develop new methods to regulate their body heat to cope with fluctuations in ambient temperature. They developed behaviours suitable for reproduction in a terrestrial environment. Their skins were exposed to harmful ultraviolet rays that had previously been absorbed by the water. The skin changed to become more protective and prevent excessive water loss.
Characteristics.
The superclass Tetrapoda is divided into four classes of vertebrate animals with four limbs. Reptiles, birds and mammals are amniotes, the eggs of which are either laid or carried by the female and are surrounded by several membranes, some of which are impervious. Lacking these membranes, amphibians require water bodies for reproduction, although some species have developed various strategies for protecting or bypassing the vulnerable aquatic larval stage. They are not found in the sea with the exception of one or two frogs that live in brackish water in mangrove swamps; the Anderson's salamander meanwhile occurs in brackish or salt water lakes. On land, amphibians are restricted to moist habitats because of the need to keep their skin damp.

Modern amphibians have a simplified anatomy compared to their ancestors due to paedomorphosis, caused by two evolutionary trends: miniaturization and an unusually large genome, which result in a slower growth and development rate compared to other vertebrates. Another reason for their size is associated with their rapid metamorphosis, which seems to have evolved only in the ancestors of Lissamphibia; in all other known lines the development was much more gradual. Because a remodeling of the feeding apparatus means they do not eat during the metamorphosis, the metamorphosis has to go faster the smaller the individual is, so it happens at an early stage when the larvae are still small. (The largest species of salamanders do not go through a metamorphosis.) Amphibians that lay eggs on land often go through the whole metamorphosis inside the egg. An anamniotic terrestrial egg is less than 1 cm in diameter due to diffusion problems, a size which puts a limit on the amount of posthatching growth.
The smallest amphibian (and vertebrate) in the world is a microhylid frog from New Guinea ("Paedophryne amauensis") first discovered in 2012. It has an average length of and is part of a genus that contains four of the world's ten smallest frog species. The largest living amphibian is the Chinese giant salamander ("Andrias davidianus") but this is a great deal smaller than the largest amphibian that ever existed—the extinct "Prionosuchus", a crocodile-like temnospondyl dating to 270 million years ago from the middle Permian of Brazil. The largest frog is the African Goliath frog ("Conraua goliath"), which can reach and weigh .

Amphibians are ectothermic (cold-blooded) vertebrates that do not maintain their body temperature through internal physiological processes. Their metabolic rate is low and as a result, their food and energy requirements are limited. In the adult state, they have tear ducts and movable eyelids, and most species have ears that can detect airborne or ground vibrations. They have muscular tongues, which in many species can be protruded. Modern amphibians have fully ossified vertebrae with articular processes. Their ribs are usually short and may be fused to the vertebrae. Their skulls are mostly broad and short, and are often incompletely ossified. Their skin contains little keratin and lacks scales, apart from a few fish-like scales in certain caecilians. The skin contains many mucous glands and in some species, poison glands (a type of granular gland). The hearts of amphibians have three chambers, two atria and one ventricle. They have a urinary bladder and nitrogenous waste products are excreted primarily as urea. Most amphibians lay their eggs in water and have aquatic larvae that undergo metamorphosis to become terrestrial adults. Amphibians breathe by means of a pump action in which air is first drawn into the buccopharyngeal region through the nostrils. These are then closed and the air is forced into the lungs by contraction of the throat. They supplement this with gas exchange through the skin.

Anura.
The order Anura (from the Ancient Greek "a(n)-" meaning "without" and "oura" meaning "tail") comprises the frogs and toads. They usually have long hind limbs that fold underneath them, shorter forelimbs, webbed toes with no claws, no tails, large eyes and glandular moist skin. Members of this order with smooth skins are commonly referred to as frogs, while those with warty skins are known as toads. The difference is not a formal one taxonomically and there are numerous exceptions to this rule. Members of the family Bufonidae are known as the "true toads". Frogs range in size from the Goliath frog ("Conraua goliath") of West Africa to the "Paedophryne amauensis", first described in Papua New Guinea in 2012, which is also the smallest known vertebrate. Although most species are associated with water and damp habitats, some are specialised to live in trees or in deserts. They are found worldwide except for polar areas.
Anura is divided into three suborders that are broadly accepted by the scientific community, but the relationships between some families remain unclear. Future molecular studies should provide further insights into their evolutionary relationships. The suborder Archaeobatrachia contains four families of primitive frogs. These are Ascaphidae, Bombinatoridae, Discoglossidae and Leiopelmatidae which have few derived features and are probably paraphyletic with regard to other frog lineages. The six families in the more evolutionarily advanced suborder Mesobatrachia are the fossorial Megophryidae, Pelobatidae, Pelodytidae, Scaphiopodidae and Rhinophrynidae and the obligatorily aquatic Pipidae. These have certain characteristics that are intermediate between the two other suborders. Neobatrachia is by far the largest suborder and includes the remaining families of modern frogs, including most common species. Approximately 96% of the over 5,000 extant species of frog are neobatrachians.
|
Caudata.
The order Caudata (from the Latin "cauda" meaning "tail") consists of the salamanders—elongated, low-slung animals that mostly resemble lizards in form. This is a symplesiomorphic trait and they are no more closely related to lizards than they are to mammals. Salamanders lack claws, have scale-free skins, either smooth or covered with tubercles, and tails that are usually flattened from side to side and often finned. They range in size from the Chinese giant salamander ("Andrias davidianus"), which has been reported to grow to a length of , to the diminutive "Thorius pennatulus" from Mexico which seldom exceeds in length. Salamanders have a mostly Laurasian distribution, being present in much of the Holarctic region of the northern hemisphere. The family Plethodontidae is also found in Central America and South America north of the Amazon basin; South America was apparently invaded from Central America by about the start of the Miocene, 23 million years ago. Urodela is a name sometimes used for all the extant species of salamanders. Members of several salamander families have become paedomorphic and either fail to complete their metamorphosis or retain some larval characteristics as adults. Most salamanders are under long. They may be terrestrial or aquatic and many spend part of the year in each habitat. When on land, they mostly spend the day hidden under stones or logs or in dense vegetation, emerging in the evening and night to forage for worms, insects and other invertebrates.

The suborder Cryptobranchoidea contains the primitive salamanders. A number of fossil cryptobranchids have been found, but there are only three living species, the Chinese giant salamander ("Andrias davidianus"), the Japanese giant salamander ("Andrias japonicus") and the hellbender ("Cryptobranchus alleganiensis") from North America. These large amphibians retain several larval characteristics in their adult state; gills slits are present and the eyes are unlidded. A unique feature is their ability to feed by suction, depressing either the left side of their lower jaw or the right. The males excavate nests, persuade females to lay their egg strings inside them, and guard them. As well as breathing with lungs, they respire through the many folds in their thin skin, which has capillaries close to the surface.
The suborder Salamandroidea contains the advanced salamanders. They differ from the cryptobranchids by having fused prearticular bones in the lower jaw, and by using internal fertilisation. In salamandrids, the male deposits a bundle of sperm, the spermatophore, and the female picks it up and inserts it into her cloaca where the sperm is stored until the eggs are laid. The largest family in this group is Plethodontidae, the lungless salamanders, which includes 60% of all salamander species. The family Salamandridae includes the true salamanders and the name "newt" is given to members of its subfamily Pleurodelinae.
|
The third suborder, Sirenoidea, contains the four species of sirens, which are in a single family, Sirenidae. Members of this order are eel-like aquatic salamanders with much reduced forelimbs and no hind limbs. Some of their features are primitive while others are derived. Fertilisation is likely to be external as sirenids lack the cloacal glands used by male salamandrids to produce spermatophores and the females lack spermathecae for sperm storage. Despite this, the eggs are laid singly, a behaviour not conducive for external fertilisation.
Gymnophiona.
The order Gymnophiona (from the Greek "gymnos" meaning "naked" and "ophis" meaning "serpent") or Apoda comprises the caecilians. These are long, cylindrical, limbless animals with a snake- or worm-like form. The adults vary in length from 8 to 75 centimetres (3 to 30 inches) with the exception of Thomson's caecilian ("Caecilia thompsoni"), which can reach . A caecilian's skin has a large number of transverse folds and in some species contains tiny embedded dermal scales. It has rudimentary eyes covered in skin, which are probably limited to discerning differences in light intensity. It also has a pair of short tentacles near the eye that can be extended and which have tactile and olfactory functions. Most caecilians live underground in burrows in damp soil, in rotten wood and under plant debris, but some are aquatic. Most species lay their eggs underground and when the larvae hatch, they make their way to adjacent bodies of water. Others brood their eggs and the larvae undergo metamorphosis before the eggs hatch. A few species give birth to live young, nourishing them with glandular secretions while they are in the oviduct. Caecilians have a mostly Gondwanan distribution, being found in tropical regions of Africa, Asia and Central and South America.

Anatomy and physiology.
Skin.
The structure contains some typical characteristics common to terrestrial vertebrates, such as the presence of highly cornified outer layers, renewed periodically through a moulting process controlled by the pituitary and thyroid glands. Local thickenings (often called warts) are common, such as those found on toads. The outside of the skin is shed periodically mostly in one piece, in contrast to mammals and birds where it is shed in flakes. Amphibians often eat the sloughed skin. Caecilians are unique among amphibians in having mineralized dermal scales embedded in the dermis between the furrows in the skin. The similarity of these to the scales of bony fish is largely superficial. Lizards and some frogs have somewhat similar osteoderms forming bony deposits in the dermis, but this is an example of convergent evolution with similar structures having arisen independently in diverse vertebrate lineages.
Amphibian skin is permeable to water. Gas exchange can take place through the skin (cutaneous respiration) and this allows adult amphibians to respire without rising to the surface of water and to hibernate at the bottom of ponds. To compensate for their thin and delicate skin, amphibians have evolved mucous glands, principally on their heads, backs and tails. The secretions produced by these help keep the skin moist. In addition, most species of amphibian have granular glands that secrete distasteful or poisonous substances. Some amphibian toxins can be lethal to humans while others have little effect. The main poison-producing glands, the parotoids, produce the neurotoxin bufotoxin and are located behind the ears of toads, along the backs of frogs, behind the eyes of salamanders and on the upper surface of caecilians.
|
The skin colour of amphibians is produced by three layers of pigment cells called chromatophores. These three cell layers consist of the melanophores (occupying the deepest layer), the guanophores (forming an intermediate layer and containing many granules, producing a blue-green colour) and the lipophores (yellow, the most superficial layer). The colour change displayed by many species is initiated by hormones secreted by the pituitary gland. Unlike bony fish, there is no direct control of the pigment cells by the nervous system, and this results in the colour change taking place more slowly than happens in fish. A vividly coloured skin usually indicates that the species is toxic and is a warning sign to predators.
Skeletal system and locomotion.
Amphibians have a skeletal system that is structurally homologous to other tetrapods, though with a number of variations. They all have four limbs except for the legless caecilians and a few species of salamander with reduced or no limbs. The bones are hollow and lightweight. The musculoskeletal system is strong to enable it to support the head and body. The bones are fully ossified and the vertebrae interlock with each other by means of overlapping processes. The pectoral girdle is supported by muscle, and the well-developed pelvic girdle is attached to the backbone by a pair of sacral ribs. The ilium slopes forward and the body is held closer to the ground than is the case in mammals.
|
In most amphibians, there are four digits on the fore foot and five on the hind foot, but no claws on either. Some salamanders have fewer digits and the amphiumas are eel-like in appearance with tiny, stubby legs. The sirens are aquatic salamanders with stumpy forelimbs and no hind limbs. The caecilians are limbless. They burrow in the manner of earthworms with zones of muscle contractions moving along the body. On the surface of the ground or in water they move by undulating their body from side to side.
In frogs, the hind legs are larger than the fore legs, especially so in those species that principally move by jumping or swimming. In the walkers and runners the hind limbs are not so large, and the burrowers mostly have short limbs and broad bodies. The feet have adaptations for the way of life, with webbing between the toes for swimming, broad adhesive toe pads for climbing, and keratinised tubercles on the hind feet for digging (frogs usually dig backwards into the soil). In most salamanders, the limbs are short and more or less the same length and project at right angles from the body. Locomotion on land is by walking and the tail often swings from side to side or is used as a prop, particularly when climbing. In their normal gait, only one leg is advanced at a time in the manner adopted by their ancestors, the lobe-finned fish. Some salamanders in the genus "Aneides" and certain plethodontids climb trees and have long limbs, large toepads and prehensile tails. In aquatic salamanders and in frog tadpoles, the tail has dorsal and ventral fins and is moved from side to side as a means of propulsion. Adult frogs do not have tails and caecilians have only very short ones.
|
Salamanders use their tails in defence and some are prepared to jettison them to save their lives in a process known as autotomy. Certain species in the Plethodontidae have a weak zone at the base of the tail and use this strategy readily. The tail often continues to twitch after separation which may distract the attacker and allow the salamander to escape. Both tails and limbs can be regenerated. Adult frogs are unable to regrow limbs but tadpoles can do so.
Circulatory system.
Amphibians have a juvenile stage and an adult stage, and the circulatory systems of the two are distinct. In the juvenile (or tadpole) stage, the circulation is similar to that of a fish; the two-chambered heart pumps the blood through the gills where it is oxygenated, and is spread around the body and back to the heart in a single loop. In the adult stage, amphibians (especially frogs) lose their gills and develop lungs. They have a heart that consists of a single ventricle and two atria. When the ventricle starts contracting, deoxygenated blood is pumped through the pulmonary artery to the lungs. Continued contraction then pumps oxygenated blood around the rest of the body. Mixing of the two bloodstreams is minimized by the anatomy of the chambers.
|
Nervous and sensory systems.
The nervous system is basically the same as in other vertebrates, with a central brain, a spinal cord, and nerves throughout the body. The amphibian brain is relatively simple but broadly the same structurally as in reptiles, birds and mammals. Their brains are elongated, except in caecilians, and contain the usual motor and sensory areas of tetrapods. The pineal body, known to regulate sleep patterns in humans, is thought to produce the hormones involved in hibernation and aestivation in amphibians.
Tadpoles retain the lateral line system of their ancestral fishes, but this is lost in terrestrial adult amphibians. Many aquatic salamanders and some caecilians possess electroreceptors called ampullary organs (completely absent in anurans), that allow them to locate objects around them when submerged in water. The ears are well developed in frogs. There is no external ear, but the large circular eardrum lies on the surface of the head just behind the eye. This vibrates and sound is transmitted through a single bone, the stapes, to the inner ear. Only high-frequency sounds like mating calls are heard in this way, but low-frequency noises can be detected through another mechanism. There is a patch of specialized haircells, called "papilla amphibiorum", in the inner ear capable of detecting deeper sounds. Another feature, unique to frogs and salamanders, is the columella-operculum complex adjoining the auditory capsule which is involved in the transmission of both airborne and seismic signals. The ears of salamanders and caecilians are less highly developed than those of frogs as they do not normally communicate with each other through the medium of sound.
|
The eyes of tadpoles lack lids, but at metamorphosis, the cornea becomes more dome-shaped, the lens becomes flatter, and eyelids and associated glands and ducts develop. The adult eyes are an improvement on invertebrate eyes and were a first step in the development of more advanced vertebrate eyes. They allow colour vision and depth of focus. In the retinas are green rods, which are receptive to a wide range of wavelengths.
Digestive and excretory systems.
Many amphibians catch their prey by flicking out an elongated tongue with a sticky tip and drawing it back into the mouth before seizing the item with their jaws. Some use inertial feeding to help them swallow the prey, repeatedly thrusting their head forward sharply causing the food to move backwards in their mouth by inertia. Most amphibians swallow their prey whole without much chewing so they possess voluminous stomachs. The short oesophagus is lined with cilia that help to move the food to the stomach and mucus produced by glands in the mouth and pharynx eases its passage. The enzyme chitinase produced in the stomach helps digest the chitinous cuticle of arthropod prey.
