Why are people from Africa so dark?
<|assistant|>
People from Africa typically have a dark complexion because they have more melanin than people from other parts of the world. Melanin is what gives skin its color and protects the skin from sun damage. In addition, the skin color of those living in Africa is also greatly influenced by the natural protection provided by the African climate. Higher amounts of melanin provide better sun protection. Generally, the darker the skin, the higher its levels of melanin, which explains why people from Africa tend to have darker skin colors than people from other continents.
