All blue-eyed people come from the same ancestor

One of the parts of the human body that contains the most… What we look at when we meet someone is their eyes. There are no more or less beautiful colors, but they attract more attention. One of the most desirable colors for people is blue eyes.

This eye color is the second most common color in the world, but only 10% of the population has it. but, Where did those blue eyes that some people have come from?

he brown It is the natural color of the human eye and is due to melanin, a pigment. Its production is regulated by a gene called OCA2It is also responsible for giving color to hair, skin and eyes.

Professor Hans Eyberg has spent years studying this gene and the development of blue eye color in individuals from around the world. His conclusion is that during our evolution, A Genetic mutation It prevents the production of melanin in the eyes, and leads to the appearance of blue.

Now, a team of researchers from the University of Copenhagen, to which Iberg belongs, has discovered this All blue-eyed people descend from a common ancestor who lived about 6,000 to 10,000 years ago.in it Neolithic era.

It appears to be a genetic change This happened when humans migrated to Europe from Africa. This would explain why initially only Caucasians had blue eyes. Later, miscegenation meant that Caucasians were not the only ones with a sea-coloured appearance.

In addition, he points out that the results indicate that the evolution of blue-eyed individuals was “very correct,” as “the mutation per person became 300 million copies in 2018.” 150 million people“.
