Will a white person turn black if they lived a lifetime in mid africa ?

You are an idiot.

Yes. Expect to gain 1-2 inches as well.

You should be ashame for asking such stupid questions. What is wrong with your vagina ?

Fuck, man. Put some black paint on your white ass. We gone but you in a cookin pot for our cannibal feast. Dumb people taste da best.

I get it:

You're testing the adage about there being no such thing as a stupid question.

The first person was correct - you are an idiot!. Natural selection does not work by making you as an individual right for the environment. Instead natural selection selects those young that are most suited for the environment, eventually over many generations your prodigy will be black, but not you.
It is like saying we evolved from monkeys. We did not we have a common ancestor (ie I am not evolved from my cousin, we just have a common ancestor in this case our grandparents.

You would definitely get tan but not black. If you are a believer in evolution we all came from Africa but it took thousands of years for our ancestors to develop lighter skin in more northern regions

No, but if a human albino jumped into a vat of black India(n) Ink, then they would turn black.

I feel as though I'm becoming braindead from reading through your comments.

This was funny and stupid yet thought provoking. A google search seems to suggest being black has to do with having fewer sweat glands

You won't turn black but you will turn paisley.

No, you can only tan so much once genetics decide what your skintone is.

Over thousands of years, natural selection would favour those with dark skin in an isolated light-skinned population living in the tropics. If Australia closed it's borders tomorrow, nobody got in and nobody got out, then in 5000 years or so the descendents of current (mostly white) Australians would be significantly darker, because natural selection would favour relatively darker-complexioned womens' birthrates. The opposite happens far from the equator, which is how European and Asian populations gradually developed lighter features.

changes like that don't happen in a couple of years or even a whole lifetime. for example if a white man and white woman went to live in subsaharan Africa and their kids only had children with other white people, it would take maybe 4 or 5 generations, perhaps longer, to develop darker skin pigmentation and generally more "African" features such as flatter nose, curly hair, and thicker lips. remember that what we look like is an adaptation to our environment, and isn't only limited to skin color. so thousands of years ago when Africans went into Europe to settle down, their facial features and skin color changed to better suit the climate (less intense sun, colder weather, etc.) but it takes a lot of time for these changes to take place.

Physically: No, that's evidently impossible, Culturally: Yes.
