The emergence of skin pigmentation dates to about 1.2 million years ago, under conditions of a megadrought that drove early humans into arid, open landscapes. Such conditions likely caused excess UV-B radiation.
What skin color was the first human?
The results of Cheddar Man's genome analysis align with recent research that has uncovered the convoluted nature of the evolution of human skin tone. The first humans to leave Africa 40,000 years ago are believed to have had dark skin, which would have been advantageous in sunny climates.
Why did humans develop different skin pigmentation?
Pigmentation, (skin color), in humans has evolved under selection pressure from the duration and intensity of sunlight. Ancestral populations near the equator were selected for dark skin, while those living in higher northern latitudes were selected for lighter skin.
