Har du blåa ögon?
Researchers from Copenhagen University have recently proven that a single mutation that emerged about 10,000 years ago is the reason why all blue-eyed people living today have that skyey eye colour. According to the scientists team the mutation must have arisen in a single individual living on the northwest coast of the Black Sea. The rear gene ‘creates’ a blue iris by turning off the mechanism responsible for generating brown melanin pigment.
