In 2008, geneticists in Copenhagen lined up the DNA of blue-eyed volunteers from Denmark, Turkey and Jordan, and every result came back the same. One mutation. One ancestor. Somewhere between 6,000 and 10,000 years ago. And the history books had the location wrong. And that's just one thread in a much bigger story about what DNA reveals about the origin of blue eyes.

In this video, we break down:

✅ Hans Eiberg's 2008 Copenhagen research and the single mutation shared by blue-eyed people
✅ Why blue eyes contain no blue pigment, and how light scattering creates the color
✅ How a tiny change in the HERC2 switch turns down the OCA2 gene and drains melanin from the iris
✅ Why scientists once pointed to Scandinavia, and what ancient DNA suggests instead
✅ The Pontic-Caspian Steppe and the Black Sea and Caucasus region as the likely trail
✅ La Braña Man in Spain: blue eyes on dark skin, 7,000 years ago
✅ Cheddar Man and the 2018 face reconstruction that shocked Britain
✅ How the gene traveled east: the Pamiri, Wakhi, Hazara, Uyghur and Kalash peoples
✅ The Tarim Basin mummies and the 2021 DNA study that rewrote their story
✅ The Yamnaya migrations and how steppe ancestry carried the trait across Eurasia
✅ Why blue eyes are most common in Northern Europe today
✅ The Scythians, the Tocharians and the ancient peoples of inner Asia
