Where do blue eyes come from?

Every person with blue eyes shares a single ancestor who lived between 6k and 10k years ago.

Research done in 2008 showed that people with blue eyes have a single common ancestor. Scientists found the genetic mutation that gives blue eyes. Before that, everyone had brown eyes said Hans Eiberg from the University of Copenhagen. He and his colleagues showed that a mutation in the 86 intron of the herc2 gene reduced  melanin production.

They discovered that the mutation arose in a single individual in the Near East 6,000–10,000 years ago during the neolithic period. This genetic mutation resulted in the creation of a ‘switch,’ which ‘turned off’ the ability to produce brown eyes.
