It seems that a genetic mutation in a single individual in Europe 6,000 to 10,000 years ago led to the development of blue eyes, according to researchers at the University of Copenhagen. The colour of the eyes depends on the amount of a single type of pigment (called melanin) in the iris of the eye. This genetic change, located in the gene next to the OCA2 gene, limits the production of melanin in the iris - effectively "diluting" brown eyes to blue. The colour of the blue eye is determined by something called melanin. Melanin is a brown pigment that controls the colour of our skin, eyes and hair.
