why are some people from africa so black?
<|assistant|>
Some people from Africa are so black because of their genetic makeup. Dark skin pigmentation is a common feature in populations from Africa who have adapted to live in high risk areas of diseases such as malaria and skin cancer from the sun, which leads to increased pigmentation as a form of protection from the UV rays. Additionally, melanin, a substance that gives skin its color, is more concentrated in darker skin, giving some people from Africa an even darker skin tone.
