chosen: Why are people from Africa so dark?
chosen: user
chosen: People from Africa are dark-skinned because they are more prone to the production of melanin, a pigment found in the skin which darkens in response to sun exposure. This occurs due to greater amounts of ultraviolet radiation present in the African continent and its surrounding areas, which leads to people with African heritage having a darker skin tone than other populations. Additionally, some genetic mutations can cause increased pigmentation as well.
