According to a new study, all those who have blue eyes have a common ancestor
A new study conducted by Danish researchers indicates that all blue-eyed people actually have a common ancestor, which means they are all related.According to the study’s findings, the ancestor lived about 6,000 to 10,000 years ago, Fox News reports.
“Originally, we all had brown eyes. But 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,” Professor Hans Eiberg of the University of Copenhagen said.
According to the researches, the switch in the DNA regulates the pigmentation of the eyes, hair and skin. If the mutation had completely deactivated the OCA2 gene, all blue-eyed people would be albinos, they said.
The research included 155 people from a large Danish family, but also several blue-eyed people born in Turkey and Jordan and the same mutation has been noticed to all of them.
