Blue Eyes Originated 10,000 Years Ago in the Black Sea Region

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.
“The question really is, ‘Why did we go from having nobody on Earth with blue eyes 10,000 years ago to having 20 or 40 percent of Europeans having blue eyes now?” John Hawks of the University of Wisconsin-Madison said. “This gene does something good for people. It makes them have more kids.”
