A team of researchers from Copenhagen University have located a single mutation that causes the mysterious phenomenon of blue eyes. And all blue eyed people are genetically related to a person who lived in the Black Sea region sometime between 6 – 10,000 years ago. The research was published in the Journal of Human Genetics. A mutation in a gene called OCA2 came into being nearly 8,000 years ago. It can be definitively traced back to an ancestor from the Black Sea.
