This may be a silly question, but since whites have lived in South Africa since 1652, and also in the US, Latin American and Oceania, I've always
wondered how long it will take for us to turn black.
I'd like to focus on melanin, or skin color issues only, and not other supposed attributes currently essentialistized as "racial" (IQ, crime,
over-population and so forth).
With skin color, science focuses on Vitamin D as a factor, and also minimizing sun damage.
Some say we have a harsher sun than previously (which should speed up evolutionary change towards a darker skin), while others argue that cultural
factors like clothes, buildings or sun-screen delay a natural process.
Miscegenation is one way to darken a nation, but won't it happen naturally?
How long will it take?
