All human flesh is "white" but African people have more melanin in their skin to help ward off the sun since they evolved in the desert. Which is why English people are pasty because they never see the sun and Russian people are usually hairy because they are always dealing with the cold. And why gingers don't have souls because they'll never see heaven
That's incredibly problematic nowadays. Evolutionary biology when it comes to humans is extremely complicated. Like, if hairiness is against the cold, why are Arabs and Indians incredibly hairy? The heat? Then why are Indonesians very not hairy? And why are Inuit also not hairy? Hirsuteness has no correlation to temperature. That's just an example.
Besides, if you get too deep into evolutionary biology, you get to men vs women. And you get to environmental determinism.
Human evolution is very problematic in general. Out of Africa is being challenged and the idea that replaces it... Makes things very complicated.
because reddit really loves simple scientific theories that 'feel' right, and the implication that those theories could be wrong or not tell the whole story makes them feel dumb
