Even if blue eyes are not that common in the Middle East it is still interesting to know that blue eyed people are all "related"
Humans have a variation in eye color. Scientists do know if blue eyes provide a selective advantage.
In a new study, researchers at the University of Copenhagen have found a genetic mutation which occurred somewhere between 6,000 and-10,000 years ago leading to blue eyes, reports Science Daily.
Since blue eyes originated from a single mutation, everyone who has blue eyes has a common ancestor,
"Originally, we all had brown eyes," said Hans Eiberg, a professor in the Department of Cellular and Molecular Medicine at the University of Copenhagen. "But a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a switch, which literally turned off the ability to produce brown eyes."
