Blue eyes are beautiful. But now scientists have discovered that all blue eyes are hiding a secret in their distant past.
Scientists believe that every person with blue eyes shares a common ancestor.
This eye color first originated somewhere between 6-10 thousand years ago as a result of a genetic mutation. The mutated gene interferes with the body’s ability to produce melanin in the iris of the eye.
Melanin is a pigment that provides color to the eye, skin, and hair. Since less melanin is produced, eye color manifests as a blue. This mutation affects only the iris of the eye and does not stop melanin production, only reduces it.
As a result, you could be staring 6,000-10,000 years into the past.
Scientists from the University of Copenhagen have tracked down a genetic mutation that all blue eyed people have in common.
