All blue eyed people can be traced back to one person who lived near the Black Sea 10,000 years ago

Did you know that all blue eyed people can be traced back to one person who lived near the Black Sea 10,000 years ago.


 


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.
