People of African descent have higher melanin production in their skin compared to those from other regions. Melanin is a pigment responsible for the color of the skin, hair, and eyes.
Africa receives a high amount of UV radiation from the sun due to its proximity to the equator. Dark skin has more melanin, which provides natural protection against the harmful effects of UV radiation, including skin cancer and sunburn.
Melanin acts as a shield against DNA damage caused by UV radiation. It helps to prevent skin damage, premature aging, and skin cancer.
While dark skin reduces the production of vitamin D in response to sunlight, it doesn't eliminate it entirely. This adaptation helps to regulate vitamin D levels in regions with intense sun exposure to avoid vitamin D toxicity.
Dark skin absorbs and retains heat more effectively than light skin. In hot climates, this can help to prevent overheating by dissipating heat more slowly.
High UV exposure can deplete folate levels in the body, which is essential for fetal development. Dark skin provides protection against this folate depletion.
African populations have diverse genetic backgrounds, and skin color can vary among different groups. For instance, people from East Africa may have slightly lighter skin than those from West Africa.
