Popular history YouTuber Feature History claims that "Hutu" and "Tutsi" were originally class distinctions rather than ethnic ones. How much merit does this claim have?
here's an answer from another thread that answers your question _URL_0_ credits to /u/gplnd
[ "A contrasting picture of human cultural diversity was recorded in the early Rwandan oral histories, ritual texts, and biographies, in which the terms Tutsi, Hutu, and Twa were quite rarely used and had meanings different from those conceived by the Europeans. In those, the term Tutsi was equivalent to the phrase \...
How did the Thirty Year's War and the Paraguay War lead to such a huge loss of life?
First: a loss of population from pre-war levels is a very different thing than direct counts of casualties. The Holy Roman Empire's population was roughly two-thirds in 1650 of what it was in 1615 (although some regions suffered much more directly), but much of the population loss were simply refugees, loss of territor...
[ "The losses of the century of war were enormous, particularly owing to the plague (the Black Death, usually considered an outbreak of bubonic plague), which arrived from Italy in 1348, spreading rapidly up the Rhone valley and thence across most of the country: it is estimated that a population of some 18–20 millio...
when microwaving food, why does it seem to get more soggy rather than crunchy?
Microwaves specialize in heating up moisture specifically. The heated up moisture just tends to steam and diffuse making crunchy things less crunchy and more damp(soggy). Feel free to fact check.

Some pathogenic bacteria, such as \"Clostridium perfringens\" and \"Bacillus cereus\", are capable of causing spoilage.\n", "The spoilage of food products caused by microbes is a concern for many sub-sectors of the food ...
Are there solar systems that are not contained in galaxies? How would our solar system be different if that were the case?
So you can contrive to have a situation where it might occur. Stars can be lost from a host galaxy via a few different means. (Mergers, Supernovae, Scattering off hard binaries, etc. Generally anything that can throw stars into different orbits.) If you have a very tight solar system, say a star and a hot jupiter, it ...

Would the Lorica Segmentata have been a good choice of armor in medieval times? Could it have retained its effectiveness on the battlefield, let's say, around 1000 AD?"
The threats on the battlefield of 1,000 AD weren't really much different to those of 100 AD; spears and arrows for the most part, with slingshot, battleaxes and swords also being fairly common. Lorica Segmentata offered adequate protection against all of those, so in that sense it was as good as ever. However, Lorica ...

why are some insects (such as flies) extremely skittish towards humans whereas others (such as ladybugs) are extremely docile towards humans, despite having similar flight abilities?
Ladybugs are toxic (or something like that) to most predators, as indicated by their flashy colors. They know that predators know not to eat them, so they have no need to run away. Flies, on the other hand, rely on their mobility to escape from predators, so they need to be jumpy.
[ "Some species, such as deer flies and the Australian March flies, are known for being extremely noisy during flight, though clegs, for example, fly quietly and bite with little warning. Tabanids are agile fliers; \"Hybomitra\" species have been observed to perform aerial manoeuvres similar to those performed by fig...
how exactly does water ruin electronics, assuming that they are turned off after and dried throughly, what damage to hardware is done that is irreparable?
Different components react differently to water. Most ICs, for example, will dry just fine, but may end up with residual water stuck underneath the chip, unable to dry. Capacitors can corrode from the inside out, and transistors do weird things when exposed to water, but immediate drying and cleansing with alcohol wi...

why doesn't the u.s. have standardized education across the board? wouldn't that make everything easier?
The US has a history of federalism and local control. It's much bigger and more diverse than Japan or the UK, so it's harder to get everyone to agree. Common Core was an attempt at standardized education, and it met major backlash pretty much across the board.
[ "Unlike the systems of most other countries, education in the United States is highly decentralized, and the federal government and Department of Education are not heavily involved in determining curricula or educational standards (with the exception of the No Child Left Behind Act).

why do male dogs pee with one leg up and female dogs don't ?
Males are marking their territory...the higher they pee, the less likely someone can pee over it. My Labrador used to also poop on top of boulders to mark his territory.
[ "Domestic dogs mark their territories by urinating on vertical surfaces (usually at nose level), sometimes marking over the urine of other dogs.

why does audio feedback always sound like a high squealing noice?
There are 2 things happening here. In a feedback loop, the microphone is picking up some of the amplified sound (because it "hears" it from the speaker) and sends it back around.

If yellow teeth are supposedly healthy and natural, why do we find pearly white teeth attractive?
I'm surprised to hear that yellow teeth are healthy. Normally, one would think discoloration signifies rot or oral disease. Do you have a source for that fact?

As the first European city founded in California, why didn't San Diego become as prominent as San Francisco or Los Angeles?
Without answering your question precisely, I'd like to point out that being the first city doesn't always make it important.

How accurate is the movie Gandhi (1982)? I read some articles slamming Gandhi (the actual person), and I don't know what to make of them.
The problem here is that there is a vast disjuncture between Gandhi the historical figures versus the popular mythology that has built around him.

I've always heard that a kink is something you enjoy while a fetish is something you have to have in order to get off.
[ "In human sexuality, kinkiness is the use of non-conventional sexual practices, concepts or fantasies. The term derives from the idea of a \"bend\" (cf. a \"kink\") in one's sexual behaviour, to contrast such behaviour with \"straight\" or \"vanilla\" sexual mores and proclivities.

Before Israelite conquered it, who ruled Jericho and where is Jericho mentioned outside the bible?
This is a good question, but I want to start by clearing up a couple of things.

If you hold in poop does your intestine still absorb nutrients or does it just kind of sit there at the end of the line?
Its called [encopresis] (_URL_0_). By the time you have conscious control, its more water being absorbed than anything else.

How can some materials resist being dissolved by both polar and non-polar solvents?
While the chemical bonds in glass are slightly polar, the bonds that hold the atoms together are quite strong and also form a very large interconnected network. It's as if the whole piece of glass were one molecule. It's not possible to dissolve it simply by surrounding it with solvent molecules. You'd need a solvent ...
