    Default Origin of Blue/Green/Grey/Colored Eyes

    I'm curious. Does anyone have definitive research that shows why West Asians, Central Asians, South Asians and North Africans tend to be the populations outside of Europe that exhibit blue or green eyes? Is it the West Eurasian part of their ancestry that explains this?

    Why does Europe (particularly Northern/North-Eastern Europe and Scandinavia) have much higher frequencies of colored eyes than other parts of Europe?

    In the case of East Asians, Sub-Saharan Africans, etc. is it some type of recent mutation?


    Another member gave me this link but it apparently seems to still be a theory and not definitive yet.

    I don't think it's mutation. Moreover I read somewhere that blue eyes are disappearing slowly. I think Pashtun have green eyes because of genetic contribution of greeks.

    UV/hot climate = more melanin = more dark eyes and hair
    UV/cold climate = less melanin = less dark eyes and hair

    Most likely an infrequent mutation, NOT due to Euro admixture.

    Mutation 1 = Brown -> Light

    Mutation 2 = Green -> Blue


    The first mutation is a little older, that's why some old populations have light eyed individuals whose eyes are not blue. That's why all Southern Europeans, Pakistans and the Uyghurs have between 4 and 10 times more green eyes than blue.

    5000 years ago the second mutation happened somewhere around Ukraine: blue.

    Greeks are a majority dark-eyed people. Pashtuns didn't get green eyes from them but mostly like their West Eurasian ancestry.

    Glad to see 18th century theories with no genetic evidence still exist.

    The black sea region makes sense I guess.

    Yes, to some extent, but cannot be applied generally, for example Eskimos should be albinos then for living in arctic zone, but they're of course more pigmented than northern Europeans...

    According to whose research do you base this conclusion?

    in my family there are 3-4 people with green eyes, I have (brown eyes) which are more common in the family. My grand mother supposedly had really sharp blue eyes, but I never saw her personally, she died when I was very young

    true there are more instances of green/brown/grey eyes. blue are there too, but much rarer.

    Do all three colors have a different origin ? is there really evidence they all descend from what person? What was his ynda?

    Could it just be a pan West Eurasian chracteristic? I mean they are indeed found among all West Eurasian (or mostly West Eurasian derived group). They are probably an ancient feature.

    Like lactose tolerance.
