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.

All blue-eyed people have one ancestor in common, born around 6,000-10,000 years ago.

....


How did this mutation get its start? Possibly when humans migrated from Africa to Europe. This would explain why only people of European descent have blue eyes. It would also suggest that all blue-eyed people share a single European ancestor.

This information is just flat out incorrect, completely out of date.

We have a 14,000 year old sample from Italy with blue eyes.

We also have OCA 2 in the southwest of America for 14k plus years.

is this statement up-to-date?
We have a lot of mutations causing diverse depigmentations on skin and hair, so without any prejudice I'm amazed it would be only one for eye depigmentation; all the way if we have only one as principal factor, we surely have others causing some variations in blue eyes (concentration and distribution pattern of pigment in the iris...).

Which statement are you referring? There are threads dedicated the the mentioned subjects. DMXX eye project and rms red hair project. There are probably others threads as well. Good luck.

I distinctly recall reading, in a book on exploration, that a few blue-eyed Native Americans were encountered along the Pacific coast of Canada. This was supposedly a first contact between white men and natives (possibly Captain Cook?).

Could be indirect influence from Inuits. Tiny portion of them have light eyes.

The Circassians are an ethnic group originally from the northwest Caucasus, between the Black Sea and the Sea of Azov, but are now more numerous in Turkey and the Middle East than in Russia. The Circassian are comprised of a number of tribes. Among the better known ones are the Cherkess, Kabardins, Ubykhs and Adyghes.

Circassians (also known as Abaza) are a very mixed lot, with a lot of European and Asian input. Many member of some tribes have blue eyes and blonde or red hair while others are dominated by people with dark hair and fair skin. Some groups have large number of members with aquiline faces; while others have almond shaped eyes and other still have round faces. Epicanthic fold, usually found among groups like the Chinese and Japanese, are also common. Circassian women are said to be especially beautiful.

They have a very higher % of Blue eyed people

My remark was addressing this very thread and the affirmation of only ONE blue eye ancestor for humanity. But if other threads give new insights on this aspect I would be glad to read them. THanks BTW

This tiny portion among Inuits could very well be the result of Vikings and modern Danes input, as well as white Americans or Canadians.

I wonder if the blue-eyed Melanesians from the Solomon Islands have been tested if they carry the same HERC2 gene all other blue eyed persons do.
Their blonde hair is confirmed to be independent from Eurasian variants.

^That makes me wonder if the Tribals in India with blue eyes have same ancestor as well.

There are data of Soviet anthropologist on North Caucasian nationalities. Adighe are part of Circassian ethinic group. We see that pure light eyes are in minority, but at other habnd, mixed colors (grene, hazel) are predominant. Pure dark are also minority.

Just received a new BigY match with a gentlemen who is Circassian, Ubykh. By coincidence I have, ‘had’, red hair and still have blue eyes. Could this be one of the avenues red hair and blue eyes travelled to the British Isles?

The authors have found that “One single haplotype, represented by six polymorphic SNPs covering half of the 3' end of the HERC2 gene, was found in 155 blue-eyed individuals from Denmark, and in 5 and 2 blue-eyed individuals from Turkey and Jordan, respectively”.What this implies, is that this mutation is a “founder mutation” i.e. it is shared by both North European individuals and subjects from Turkey and Jordan. All blue-eyed individuals indeed carry the same mutation which seems to have appeared about ten thousand years ago. Before that, everyone had dark eyes. The first blue look appeared on earth during the Neolithic period (about 6-10,000 years ago) when our ancestors left the region of the Black Sea for a better future, and built settlements in Northern Europe. Ever since, blue eyes have cleared millennia, gliding successfully through time.

Blue eye color in humans may be caused by a perfectly associated founder mutation in a regulatory element located within the HERC2 gene inhibiting OCA2 expression.
