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.

I do not buy this. When I was a kid, there was a man named Mr. Gartside. He had 4 daughters. One was blonde with blue eyes. One was black haired with brown eyes. One was a red head with hazel eyes. And one had brown hair and green eyes. That blows their premise all to hell. Both Mr. Gartside and his wife had brown hair and blue eyes. It was the craziest thing I have ever seen. All of the children’s hair color and eye color was distinct!

What about the milkman, mailman, and grocery delivery boy?

One common ancestor around 6,000 years old. Where have I heard that before? Andy? Anton? A something I think... wink

I hope you realize I was being sarcastic. I mean...there really are a high percentage of actors, actresses, models, etc., who are blue-eyed, and most of them are leftists. So I leave you to make your own conclusion.

Funny, I don’t think Italians are known for blue eyes. But then, maybe he’s more northern Italian.

Heh... I’m not sure the actual *name* of the first blue-eyed persian, er, person is known, but maybe his or her parents named him or her “Persia” — a good name for boy or girl. ;^)

That’s interesting. All of my responses were “blue”, but it still didn’t result in 100% blue. 99.6%.

An edit from the keyword follows, there were two or three others that didn't look immediately related, and I plan to crash and didn't feel like checking.
