Our happy hour fact to amaze your drinking buddies with.
Every blue-eyed person can be traced back to a shared ancestor.
The first pair of blue eyes appeared between 6,000 and 10,000 years ago as a result of a mutation in the OCA2 gene, which caused a reduction of melanin in one lucky human's iris. A team of researchers analyzed 800 modern-day blue-eyed folk
, from Northern Europe to the Middle East, and found that each individual shared a carbon copy of this particular mutated DNA segment.
"We can conclude that all blue-eyed individuals are linked to the same ancestor," said geneticist Hans Eiberg
. "They have all inherited the same switch at exactly the same spot in their DNA."
Imagine how much of an outcast that first blue-eyed person probably was
. Keeping that in mind, the next time you see a green-haired person, don't immediately assume an attention-grabbing dye job. They could be the future.
