Genetics Drive Ancient Human Skin Color Diversity, Study Says (Video)
A recent study published in the esteemed Journal Science challenges conventional beliefs about the evolution of skin color in ancient humans. Contrary to the notion that dark skin evolved in Africa as a defense against UV radiation, researchers identified genetic variants for both light and dark pigmentation that date back between 300,000 and 1 million years. The findings suggest a more nuanced history of skin color diversity among human populations, challenging the idea that all ancient humans shared a uniform complexion.

The study reveals that some dark skin tones evolved from less pigmented variants, indicating a complex interplay of genetic factors over the course of human evolution. The research also sheds light on the shared ancestry of certain skin traits between modern humans, Neanderthals, and Denisovans, challenging preconceived notions about the appearance of our ancient relatives. The study underscores the need to reevaluate assumptions about the ancient world and highlights the intricate relationship between genetics, environment, and human evolution.
