This fur served as a sunscreen but eventually was lost so people could remain active without overheating.
At this point, skin developed a permanent pigmentation that was darker to accommodate exposure to the ultraviolet (UV) rays of the sun.
According to scientists, these changes in skin color are examples of natural selection designed to protect skin from sun damage.
It took thousands of years for humans to develop the darker skin color caused by the pigment melanin. For nearly two million years, melanin has been helping humans manage their exposure to sunlight.
Melanin permits enough UV radiation for the creation of vitamin D, which assists with calcium absorption. At the same time, it protects skin from the harsh UV radiation that can destroy folate that is essential for the division of cells. Continue reading
