has anyone got an y ideas (proof would be ideal) on where and when and where blue eyes originated.
Iread  it was in the caucauses 6,000 years ago.
Ipersonally thought it was much older maybe 50'000? (onlly because they only really occur in people of euasain decent and have exsisted before)
I hope this is not offending anyone I'm only here to learn !

I find the suggested date of 6000 years ago very very hard to believe.  That s too lat even for the Neolithic farmers to have spread the gene,  It already hard enough to get the head round the idea that most y DNA arrived in the copper age but to also attribute autosomal stuff like eye colour to that period is hard to accept.  Blue eyes are very common (about 70%) in Ireland which is usually thought of as a place remote from most of the later invasion waves and where the oldest genes would survive.  So, I have always assumed that blue eyes is some autosomal trait that goes back to the hunter gatherers although there is no proof.

23andme Trait report:

"6,000 to 10,000 years ago A mutation event may have created the version of the SNP that determines blue vs. non-blue eyes. Scientists in 2008 hypothesize that this mutation event took place in a population living somewhere around the Black Sea during the Neolithic expansion. (sources)

Eiberg et al. (2008) . “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.” Hum Genet 123(2):177-87. "

I notice there was no mention of grey eyes, which i belive  are seperate coulor
they to are a surposed to be a result of decolouration.they appear more in easetrn europe through to russia and finland there could be some confussion but i would be surprised if the guys doing the research didnlt know this.
ehe idea of  grey eyes being assoseated around 6'000 bc and coming to europe with finno/urgrian peoples and even their ancestors is very beliveable.
but i have to agree with the huter/gather for the introduction blue eyes especially as they are regressive. the 70% in ireland would require nearly complete repopulaeion would it not.
i think this needs far more research

My maternal Great Uncle, who's mother was German born in West Prussia had Gray eyes as listed in some government papers.

I have the Blue Eye Genotype but have Hazel which is only a 1% change of having with this gene.

http://en.wikipedia.org/wiki/Eye_color

has a nice chart of the Blue eye coverage in Europe and also states:

Gray eyes are most common in European Russia, Sweden, Finland and the Baltic States[citation needed]. They can also be found, albeit rarely, in parts of Norway.[32] Gray eyes are also common among North Africans. Under magnification, gray eyes exhibit small amounts of yellow and brown color in the iris. Ultimately, there are at least two things that could determine gray eye color. The first is the amount of melanin made, and the second is the density of the proteins in the stroma.[39]

A gray iris may indicate the presence of a uveitis. However, other visual signs make a uveitis obvious. Gray iris color, as well as blue, are at increased risk of uveal melanoma.[40]

Visually, gray eyes often tend to appear to change between the shades of blue, green and gray; this is because gray eyes are, as already mentioned, extremely light.

read the science link on the 6'000 bc origin and it seems to sound truer to  grey eyes  they talk of lack of colour.
they may not have made a ditinction or accounted for grey/blue mix
 we need mre info all round
we might not all be on the same page?

I have blue eyes, as do my two brothers and my sister. When I was young I used to get compliments about my eyes, sometimes from girls I didn't even know (which was very nice). Now I wear glasses, so I don't get the compliments anymore.

Anyway, my dad has light brown eyes, and my mom's eyes are blue. Since the gene for blue eyes is recessive, I know my dad carries it and passed it on down to us; otherwise, we wouldn't have blue eyes.

I also know from researching my father's line that most of the males in it had blue eyes, because there are descriptions of some of them extant. But my great-grandfather married a woman with brown eyes: she was described as having brown hair and brown eyes and a "magnolia-petal" (very fair) complexion. I think she passed brown eyes on to my grandfather, who passed them on to my dad, but each of them also carried the gene for blue eyes.

Thus blue eyes skipped a couple of generations (my grandfather and my father) on my male/y-dna/surname line but popped up again with my generation.

My eyes are Brown

My Father's were kinda blue/grey/green, and I have one brother with hazel, one brother brown.

My Father's Father had brown eyes according to his military enlistment papers.
Noy sure about his wife?

My Mother had brown eyes.
My Mother's Mother had very blue eyes. Her maiden name was Stewart.

Everybody in my family, from both my mother and my father side, got blue eyes, so no surprisingly I also have blue eyes. Mine are light blue with a yellow ring around the pupil.

IS that not classed as grey with the yellow orgrey/blue. Its exactly this got me confused. Is grey a variation (mutation) of blue or have a completely different origin?
