According to the latest research that is now known among people is “all people with blue eyes have a single ancestor.”
A group of scientists has traced down due to a genetic alteration it happened and it leads to blue eyes. This mutation was occurs and declare almost between 6,000--10,000 years ago. And it is said that, before then, there were no existence of blue eyes. "Originally, as we know that we all had brown eyes," said Hans Eiberg from the Department of Cellular and Molecular Medicine at the University of Copenhagen. Further added that, the mutation attacked on the OCA2 gene so called, it is involved in the creation of melanin, this pigment known as that it gives color to our skin hair and eyes. "Eiberg said. The genetic mutation that happened in almost 10,000 years ago it affect the same gene so called OCA2 gene that exist in our chromosomes so due to this it turns creating blue eyes ability has been turned off, so due to this a new color of eyes exist in the world called blue, A condition that is known as albinism according to this condition if OCA2 gene has totally turn down then our eyes, and skin should be less-melanin. Several generations, segments of inherited DNA and they get shuffled so that persons have changeable sequences. According to some other researches it is proved that all having blue eyes belong to an individual scientist get DNA test from many countries like india and Jordon and they said the DNA series didn’t have sufficient time to get mixed up. And it is further explained that few of these segments, though, that haven't been reshuffled known as haplotypes. And an interesting point is if a collection of individuals shares long haplotypes that gives the sense the series arising very recently in our human.
