Scientists are today's blue-eyed people as a result of a mutation that actually argues that this has become. Professor of the University of Copenhagen. Hans Eiberg "In fact, all of us brown eyes," he says. Blue eye color is probably the Black Sea, the eastern or northwestern part of Europe to the north of the region's great agricultural migration ile10 6, 000 years ago emerged.
"That's my guess, but it also may have occurred in the north of Afghanistan," he said. Prof. Eiberg, so-called OCA2 gene, this mutation has changed, so the mechanism for producing brown eye "shut down" says. OCA2 gene, hair, eye and skin color that is involved in the production of melanin. Completely stopping the functioning of this gene mutation occurring in the aforementioned genes, only restricts its field of activity. In this way, decreasing the production of melanin and eye color, turning blue.
If the OCA2 gene had been left completely out of the function of this gene are albino people, hair and skin of any color görülmezdi article. Prof. for research. Eiberg and his team in India, Denmark and Turkey, studied the blue-eyed individuals. The results of research findings is seen as the professor began in 1996.
"Blue-eyed all the people who fully identical with the DNA has a point. Therefore, blue-eyed people would remove all of them have the same ancestor, "he presented a report journal Human Genetics.
