Why Europe’s First Blue-Eyed Humans Had Dark Skin?

Why did ancient humans get blue eyes thousands of years before white skin? Evolutionary biology says useful traits spread first. Skin color controls life-or-death functions like UV protection and Vitamin D synthesis. Eye color does neither. Yet ancient DNA from fossils like Cheddar Man and La Braña 1 reveals that hunter-gatherers had dark skin and blue eyes long before pale skin became dominant in Europe. In this video, we break down ancient genomics, human evolution, and the real reason pale skin took so long to take over: the agricultural revolution. Discover why the switch from hunting to farming forced an abrupt dietary crisis, why the gene for lighter skin arrived with Anatolian farmers, and how neutral genetic drift allowed the blue eye mutation to spread completely unchecked.

What did ancient DNA sequencing reveal about Cheddar Man and La Braña 1? Why didn't low sunlight in Siberia cause blue eyes to evolve? How did the arrival of agriculture cause severe Vitamin D deficiencies and bone deformities like rickets? What is the difference between selective evolutionary pressure and neutral genetic drift?
