New research shows that people with blue eyes have a single, common ancestor. A team at the University of Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of the eye colour of all blue-eyed humans alive on the planet today.
A few facts about people with blue eyes. Being blue-eyed myself... I find this quite true. But what would the creator of this say about brown eyes? Green eyes? I'm sure many people with these qualities have a diverse range of eye color... Hm. :\
