People aren’t black. Where’d you get that from? You must be one of those chronically online dorks who can’t stop playing Minecraft and now your brain is so fried you think endermen are real.

Homo sapiens originated in Africa and expanded outward into the rest of the world. White skin is an adaptation to climates that receive less sunlight in order to prevent vitamin D deficiency. However, people only evolve white skin once they move into a climate with less sunlight and live there long enough for environmental pressures to select for white skin. And there’s evidence that human actually got to Britain before that happened. DNA from the remains of the first Homo sapiens in Britain shows they still had dark skin.

The whole concept of race is socially constructed. The truth is that Europeans are actually nothing more than pale sub Saharan Africans with significantly reduced genetic diversity with a little bit of Neanderthal DNA mixed in.

You can actually tell that our species originated in Africa from our DNA. Humans evolved in Africa and as we migrated out of Africa, there were chokepoints along the way. So a relatively small number of individuals who left Africa’s descendants ended up populating Eurasia. So the farther you go from Africa, the less genetically diverse indigenous populations are and the less pure their DNA is. Sub Saharan Africans have very little Neanderthal DNA, less than 1%, while Europeans are not pure Homo sapiens, they’re mixed with Neanderthals, and then Asians are mixed with Neanderthals and Denisovans.

So native Americans have the least genetic diversity, Asians have more than native Americans, Europeans have more than Asians, and then Africans have more genetic diversity than Africans, Asians, and native Americans combined.

It’s actually kind of interesting, a lot of the traits we associate with different races are found in sub Saharan Africans. For example, some black people actually have red hair, and there are some tribes, for example the Khoisan people who have monolids like East Asians. So it’s not the case that different races are actually genetically distinct groups, it’s just that people outside of Africa have less genetic diversity due to inbreeding, so certain traits like red hair or monolids became much more common in other parts of the world, but they’re not the result of new genetic mutations that don’t exist in sub Saharan Africa. There are no genetic subdivisions of humanity.
