With the new genetic studies have found that the presence of the blue eye, in both men and women living in the world, due to the same genetic mutation, called HERC2. Following the information, has gained during the experiment, the first carrier blue eyes lived about 7-10 thousand years ago. Perform discovery was possible thanks to a DNA fragment extracted from the teeth of ancient man. It was found that people whose remains have been studied, has been endowed with blue eyes.

Scientists were able to determine that all blue-eyed boys and girls have a common ancestor, who for four generations older than us.

But when the human species emerged from Africa and dispersed around the planet, the activity of the pigmentation of the skin and the eyes start to fluctuate and change due to environmental influences.

Such processes have been associated with mutations in the genetic component OCA2. Previously, doctors believed that blue eyes fixed in one of the variations of this hereditary component.
