A diglossic situation with a high-prestige variety (the superstrate) and several low-prestige languages (the substrates) characterized the settings in which creoles developed. Therefore, creole languages can be said to have several parents, and possess as well many often recurring features that appear ex nihilo. Thus, the problem of determining relationships between creole languages and other creoles or unrelated languages has long haunted creolists and been recognized as one of the challenges in the field.",

The second part examines the various scenarios proposed to account for the emergence of creole languages in the light of phylogenetic networks. To this end, samples of various sizes and including creoles as well as non-creole languages (mostly languages involved in the emergence of creoles) were used in order to visualize the impact of the various languages present in the contact situation on the new vernaculars. The final part deals with the typological status of creoles, a topic hotly debated in creolistics (e.g. DeGraff 2003; McWhorter 1998 McWhorter , 2011 . Basing our analysis on samples of languages selected from the World Atlas of Linguistic Structures (Dryer and Haspelmath 2011, hereafter WALS), we will show that phylogenetic methods represent a unique tool for exploring the relationships between creole languages and other languages of the world and can provide invaluable insights into questions on language birth and evolution.",

In this sense, we voluntarily tipped the balance in favor of the languages that we know were present at the time when Seychellois emerged and must therefore have provided the feature pool from which the various items were available options for competition and selection in this framework. The network in Fig. 4 shows that even though only languages involved in the creation of Seychellois were included, the creoles cluster together, which goes against the predictions of a feature pool view, according to which Seychellois would be expected to appear close to the languages that were involved in its formation. The topology of the creole cluster in this and previous networks remains strikingly similar, without affecting the position of Seychellois in the lower right side of the graph.

In order to further increase the number of languages included, we have kept the 4 features which were shared by at least 80% of the CCS creoles. The resulting tree is presented in Fig. 9 . In this final graph, the creole cluster is once again unequivocally identifiable. This time, a majority of the creoles (16 out of 18) are present on a single branch, while two creoles, Krio (cKRI) and Berbice Dutch (cBER) appear on an adjacent branch together with three Austronesian languages, Loniu (Xlon), Motu (Xmtu) and Tahitian (Xtah). The graph in Fig. 9 thus provides conclusive evidence as to the status of creoles: they do form a coherent group of languages that can be distinguished solely on synchronic grounds, as is clearly visible in this, and in previous graphs.",

The problem of the classification of creoles was shown to be a manageable task with the help of phylogenetic networks. The various theories seeking to account for the similarities between creoles were investigated with the help of phylogenetic networks, and it was found that the chosen analysis was advantageous in that it allowed to graphically represent the relationships between the various languages involved in the emergence of creoles. Finally, the controversial question of whether creoles form a distinguishable subgroup among the world's languages was similarly satisfactorily answered using phylogenetic trees. Moreover, we introduced different ways of depicting the results, where color codes were used so as to instantly identify linguistic patterns.",

"text": "The study conducted by Parkvall (2008) was the first to make use of quantitative crosslinguistic data for creoles, and the results presented strongly suggested that creoles are structurally distinguishable from non-creoles from a simplicity point of view. In his investigation of the complexity of creoles, Parkvall selected 43 features, 37 of which were taken directly from the WALS (Dryer and Haspelmath 2011), with a further six added by that author. These features were used to calculate the relative complexity of the 155 languages included in the WALS for which at least 30 features were known (see Parkvall 2008 for the selection criteria). He then added data on 30 creoles and pidgins with diverse lexifiers (2008: 278) , some of which are also found in the CCS sample: Dominican, Guinea Bissau, Haitian, Jamaican, Nubi, Negerhollands, Palenquero and Tok Pisin, i.e. almost half of the Holm and Patrick sample. Parkvall interpreted his results as evidence that creoles are structurally less complex than other natural languages. Consequently, another conclusion reached by the author was that creoles form a typological group characterized by a relatively low level of structural complexity.The dataset used by Parkvall (2008) also served to provide additional evidence that creoles do indeed form a typological group on the basis of a quantitative empirical analysis. The strongest piece of evidence Bakker et al.'s (2011) large-scale investigation presents relies on Parkvall's (2008) data: 34 creoles and pidgins distinctly cluster in a network including 155 non-creole languages of the world. However, the validity of the results is somewhat undermined by the fact that the data which allowed the authors to reach this conclusion were specifically selected on the basis of creole properties, in that Parkvall selected the features in WALS that could be quantified in terms of complexity (e.g. presence versus absence of a grammatical distinction, or less versus more of a particular phenomenon). Thus, one could object that the results do not really reflect what the authors claim them to (see also Kouwenberg 2010 for a critical assessment).In order to provide additional, and this time irrefutable evidence, these results must be replicated with different samples and different features. This is what will be attempted in this section, first with the CCS languages and features used in the previous section, then with various samples of WALS languages and features.",

The major linguistic families are indicated with colors in order to facilitate the interpretation of Figure 6 : NJ tree of 50 languages with 18 binary features the graphs (cobalt blue = creoles; cyan = Nilo-Saharan; dodger blue = Afro-Asiatic; green = Indo-European; light blue = Niger-Congo; olive = Austronesian; orange = Austro-Asiatic; pink = Altaic; purple = Uto-Aztecan; red = Australian; tangerine = Trans New Guinea; yellow = Sino-Tibetan).A cluster consisting of all the creoles is immediately visible in the right end of the tree.
