A team of researchers from Copenhagen Universityhave 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.
Dr. Hans Eiberg claims that before this time, every human being had brown eyes. “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,” Eiberg said.
When blue-eyed peoples from Jordan, Denmark and Turkey were examined, their genetic difference was traced back to the maternal lineage according to Eiberg’s team.
The brown melanin pigment is still dominant. However, following the last Ice Age, Europeans developed this rare mutation that differentiated them from the rest of the human race.
Ninety-five percent of Europeans in Scandinavian countries have blue eyes. They are also found to have a greater range of hair and skin color.
Comparatively, Europe has a wider variety of hair color and skin pigment than is found in any other continent in the world. These mutations are recent as Europe was colonized only a few thousand years ago, say mainstream scientists.
Through interbreeding, the brunette with blue eyes was evidenced about 25,000 years ago. Researchers attribute this to ancient interbreeding with Neanderthals.
Although no Neanderthal DNA has been found in modern Homo Sapien-Sapien, mainstream science clings to this theory as fact because they haven’t come up with anything better.
“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.”Add This to Technorati Faves
