ok so you cant see the colour in this pic but this girl obviously has eyes that arent brown or black. or hazel for that matter. I saw a few weeks ago, a somali man of about 45/50 years old with BLUE eyes, not a cataracts, no, but his eyes were a blueish grey. why does this occur if their enviroment is not cloudy?

Gelaye, You're subscribing to Lamarckian evolutionary theory--i.e., that a group's traits will "evolve" to the topographical environment. Reminds me of 19th Century Darwinists who thought that Africans in England were getting whiter because the northern climate was making their skin "evolve". [We laugh today, knowing that they were in fact getting whiter through interbreeding.] Keeping to that reality, east Africans probably have occasional blue eyes not because of "evolution". [As you yourself point out, fair eyes are a liability in a sunny climate.] So it's not "evolution" at work, but Caucasoid genes floating around in the East African populace. Semites have low--though appreciable--rates of blondism, and Semites have mixed back and forth with east African populations for millennia. (I saw a Palestinian kid on a documentary with blue eyes and dark blond hair. Likewise, one of the men in Saddam Hussein's cabinet had fair skin and red hair. Even the prophet Mohammed was, according to tradition, a redhead.) And we know that Semites with low levels of these recessive traits have mixed with Africans---- So the conclusion is obvious: The girl in the picture had parents with alleles from distant Caucasoid ancestors. These faint genes floated around, recessively, for countless generations. Perhaps centuries. Then a man carrying that particular allele, coincidemtally married a woman with the same allele--and it triggered the long-hidden trait. It's called, in layman's terms, the "throw-back" gene. P.S.--There's a great example of this from the 1950s in South Africa. Phenotypically white Afrikaaners had three children. The first two were little blond boys. The third was a little girl different from her siblings and parents in one important respect: She was black. The white couple were as shocked as anybody. They had family photos going back generations. All their ancestors were white for as long back as great, great-grandparents. But way back in the 1600s, they did have at least one black ancestor. The alleles that controlled those traits floated for centuries, hidden in phenotypically white people--until, by random chance, a man bred with a woman who had the same alleles and the "black genes" that were hidden were activated. Here's a pic of Sandra Laing and her dismayed father. And here's her as a woman:

cataracts or Glaucoma probably for most of them.

It's not as though there's much negroid about that girl other than her skin and hair.

The girl in the picture probably has brown eyes. Pictures taken with that kind of contrast give the illusion of light eyes when in fact the eyes are usually dark brown.

She appears very Caucasoid, much more than the Semitic traits many East Africans have.

cataracts or Glaucoma probably for most of them. Thats most likely. Diseases of the eye can produce such effects. The 2nd common option is admixture and recombination by chance and the least common mutation by chance.

A Maasai elder, again light-eyed as far as I can make it out: The more progressive features make the whole type sympathic (and it doesn't threaten anyone, they stay where they are).

She is an afar girl a southern cushites practically indistinguishable from Somalis, at least thats what the site where the photo was taken from says.
Her features are aslo typical for and afar and a somali, even without the semetic influences. Northern Ethiopians like the Amahara and Tigrinya have more semetic influence because of centuries of absorbing immigrants from Yemen.

She's Aethiopid, not Caucasoid.
