New research shows that all blue-eyed people share a common ancestor. This person lived more than 6,000 years ago and carried a genetic mutation that has now spread across the world.
The exact cause remains to be determined but scientists do know that eye color began to change long before recorded history began. The following is a transcript of the video.
All blue-eyed people have one ancestor in common, born around 6,000-10,000 years ago. Blue eyes are caused by a gene mutation. For years, researchers had searched for it on the OCA2 gene. The OCA2 gene determines how much brown pigment is in our eyes. But what they were looking for wasn't there at all.

I think I remember hearing that he’d gotten into a fight over a girl..
Could there have been OTHER mutations at OTHER times?
Great minds think alike.
It’s not always as straightforward as many seem to think. Three of my four grandparents had blue eyes. Only my maternal grandfather had brown eyes. My mother has brown eyes. My father had blue eyes. My eyes are brown. So are my sister’s.
Ok. I have twin nieces, fraternal, one has bright blue eyes, the other dark brown eyes. Wouldn’t they both have the same ancestors?
Shem, Ham, or Japheth?
Correct. At 15, a fight with his friend over a girl they both liked...
tow-head not toe head
Total BS, without any kind of proof.
Thank you, T! I’ve got green eyes but I was born with blue... they changed to gray around 6 months and then green around 9 months. Weird huh?

Not really. When babies are born their melanin is not completely dispersed. In black, Asians and other dark skinned people the melanin is found usually on back and buttocks and is so concentrated it looks like bruises. with white babies there is not so much of a concentration so it is not as apparent.
It takes up to two years for the melanin dispersal to complete.
Scientic American did a great analysis of that some years back, just to add to the confusion!
I say it was Japheth.
My eyes are green hazel with little tan spokes branching out from the iris, just like #41 in post 104. Both my parents had blue eyes.
The genetics basically determine whether you have brown eyes or other than brown eyes.
Once the gene is turned off for the brown pigmentation in the iris, the shape and construction of your eye determine whether you have blue, green, hazel, grey, violet, or some other light eye color based on how your iris refracts and reflects light.
For those whose eye color changes, ambient lighting, pupil dilation, atmospheric pressure, intraoccular pressure, hydration levels, may all affect your eye color.

I’m descended from Charlemagne, my uncle says so.
He failed to realize that so is everyone else with a drop of White blood.
Are you saying they are descended from a bastard?
I’ve never quite understood how it was possible that he could be the single ancestor of White folks living today.
My father got a DNA ancestry test thingie and he had me take it, so we’re waiting on the results.

It was just so long ago, the seed is spread
” Basically, everyone alive in the ninth century who left descendants is the ancestor of every living European today, “
Yeah, mine too as well as my mother, but my eyes are brown. Does that mean I don’t have the same ancestors as my mother? Story makes no sense.
