> Our dark-skinned ancestors in Africa began migrating northwards from Africa about 70,000 years ago. As these people moved further north, they were exposed to less of the sun’s UV radiation, and their D-vitamin levels in the blood dropped. This gradually impaired their immune system and made them more susceptible to infections. The evolutionary effect was that individuals with slightly lighter skin had better health and were the ones best adapted, and therefore passed their traits forward. Over the millennia, this led to light skin becoming an evolutionary advantage, making the people who settled in the northern hemisphere gradually become light-skinned. The USA is a shining example of this observation, where the health status and lifespan of the African-American population group are much lower than that of the white population.

Tl;dr, I just realized something: The universe is out to get all of us, and if old straight white man is the only thing you see in it, maybe it's a you problem.
