All blue-eyed people in the world are descendants of the same person!, revealed in new research

There are very few people with blue eyes in the world, but a lot has been written about blue eyes. It is also considered a high standard of beauty. Scientists believe that only 8 to 10 percent of people in the world have blue eyes. The blue color of the eyes can also disappear with increasing age. However, many people always have blue eyes.

New research has come out on people with blue eyes. It states that every blue-eyed person is a descendant of a European person. He is a descendant of European man who lived about 6000 to 10000 years ago. Although you may find it shocking, the study says that this study has identified a gene mutation that occurred around 6 to 10 thousand years ago.

A genetic mutation affecting the OCA2 gene in our chromosomes resulted in a change that literally affected brown eyes, said Professor Hans Iberg of the Department of Cellular and Molecular Medicine at the University of Copenhagen. The research says the mutation occurs in a gene called HERC2, which turns off OCA2. This gene determines how brown or black our eyes will be. When the OCA2 gene is turned off, the eyes are blue. As far as the ancestry of the same European person is concerned, there is evidence that every blue-eyed person alive today has the same mutation as that person 6 to 10 thousand years ago.

By the way eyes are usually brown: Scientists say that normally all humans have brown eyes. However, their color may vary. Scientists say that people whose eyes are not fully developed in childhood have blue eyes. However, they may turn completely brown as they age.
