Why Africans are black?

Answer 1

African Americans are black for their ancestors originated there and was from Africa and they came to America so hope you learned something

Black is a political term used to define those with some or all African ancestors, in some places, people from India, or anyone who has dark skin & coarse hair.

Answer 2

Dark skin is an adaptation to hotter climates. Africa is generally hot, so humans adapted and became black.

Furthermore, Africans are not the only "black" people in the world. Several unrelated groups such as the Aborigines of Australia and Negritos of Asia are dark-skinned, but are not directly related to Africans.

Answer 3

Dark pigmentation of skin helps to protect the skin against damage from the sun's ultraviolet radiation, so people in tropical latitudes evolved darker colouring than those living further from the equator.

There is another reason why Africans are darker even than other tropical peoples. Human males of all races have a sexual preference for lighter-skinned females (which is where the expression "the fair sex" comes from). In tropical locations outside of Africa this counterbalanced the evolutionary pressure for darker skin for UV protection, meaning that the normal skin colour in those areas is a mid brown colour.

In Africa however, the tsetse fly (which makes use of working animals for farming almost impossible) means that farming requires more human labour than in other parts of the world. This meant that men historically selected wives not according to their sexual attractiveness (biasing towards paler skin) but according to their ability to work hard all day in the sun (biasing towards even darker skin). This is why Africans are darker than other indigenous tropical peoples, and also why Africans were the chief targets of both the Arab and Atlantic slave trades.
