Blue-eyed humans have a single, common ancestor

New research shows that people with blue eyes have a single, common ancestor. Scientists have tracked down a genetic mutation which took place 6,000-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today

"Originally, we all had brown eyes," said Professor Hans Eiberg from the Department of Cellular and Molecular Medicine. "But a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a "switch," which literally "turned off" the ability to produce brown eyes." The OCA2 gene codes for the so-called P protein, which is involved in the production of melanin, the pigment that gives colour to our hair, eyes and skin. The "switch," which is located in the gene adjacent to OCA2 does not, however, turn off the gene entirely, but rather limits its action to reducing the production of melanin in the iris -- effectively "diluting" brown eyes to blue. The switch's effect on OCA2 is very specific therefore. If the OCA2 gene had been completely destroyed or turned off, human beings would be without melanin in their hair, eyes or skin colour -- a condition known as albinism.

The blue eyes came after the whiteness.

“Originally, we all had brown eyes…”

He knows this how? 🙄

Most likely a Germanic forest dweller, probably named Otto der Blauäugige.

Perhaps Mrs. Gartside got around? That is another possibility.

But both eye color and hair color can occur on a gradient with the right genetic combination. The Gartside girls fall within the spectrum of possibility.

Journal Reference:

may

be caused by a perfectly associated founder mutation in a regulatory element located within the HERC2 gene inhibiting OCA2 expression. Human Genetics, 2008; 123

Just as I expected.

“He knows this how?”

Simple deduction - clearly the races diverged prior to the evolution of blue eyes or they would be present in people without European ancestors. It is pretty unlikely that brown eyes exterminated the blue-eyed gene in every race but Whites.

> All of the children’s hair color and eye color was distinct!

He should have kept a better eye on his wife.

Thulsa Doom had blue eyes, and was said to live a 1000 years.

Imagine he had an occasion to sire once in a while, maybe.

Ah. If they were brown you’d have had that old conundrum of whether to believe her....

I started out with brown eyes. They went hazel in my mid 20’s. As time went by, they started turning green. I am in my mid-60’s and I now have a green colored eye. My father’s eyes were a beautiful shade of lighter green. My eldest daughter has those exact eyes. My mother’s eye color was a solid brown, which is the eye color of my youngest daughter.

Mia Farrow’s son Ronan has that beautiful blue eye, and the face is quite similar to Sinatra’s. I tend to believe the rumors that Mia and Frank are his parents.

I saw at least two people over a 20-year period whose medical records showed that they had one blue eye and one brown eye.

I sat next to a girl in HS Biology class that had that same thing, one brown, one blue.

I had a Huskie with beautiful steel blue eyes, but your image friend has a more turquoise look. Very nice if authentic.
