Unveiling the Genetic Mutation Behind Blue Eyes
The captivating blue color of eyes is not a result of chance but rather a consequence of a genetic mutation that occurred thousands of years ago. According to Professor Hans Eiberg from the Department of Cellular and Molecular Medicine at the University of Copenhagen, all humans originally had brown eyes. However, this common ancestor experienced a genetic mutation affecting the OCA2 gene, which resulted in the creation of a “switch” that limited the production of melanin, the pigment responsible for eye color.
