Blue eyes, a recent mutation, trace back to one ancestor near the Black Sea 6,000-10,000 years ago. This single genetic change transformed human appearance. The blue eye phenomenon traces back to a single genetic mutation in the OCA2 gene, which occurred in one individual between 6,000 and 10,000 years ago. This mutation reduces melanin production in the iris, creating the blue color. Before this time, blue eyes did not exist. Originally arising in the Black Sea region, this new trait spread thr
