chosen: Some people from Africa are so black due to high levels of melanin in their skin. Melanin is a pigment responsible for giving skin, hair and eyes their color. The more melanin a person has, the darker their skin and hair color will be. This is also why African people generally have more distinct features such as kinky hair and wide mouths.
