These striking eyes have always been associated with the Caucasians. However, it is also a historical truth the Africans colonised Europe over 10, years ago and they were infact the first homo sapiens to cross Europe to Asia and South Pacific.

People pay very little attention...

This photo is, perhaps, the best example of a black African, non-mulatto, non-albino, with blue eyes. Also, the boy in the picture does not appear to have Waardenberg Syndrome, also a source of blue eyes in blacks. This leaves the strong possibility of a rare mutation of a key eye color gene.

There are four types of Waardenburg Syndrome, with a mix of possible characteristics as the determinant. The boy in the picture above is displaying two major symptoms of type 1, as does the previous boy perhaps ; bright blue eyes and dystopia canthorum, a condition where the inner corners of the eyes are set more widely apart, but with normally distanced eyes.

Waardenburg occurs once in every 42, births, and is a deficiency inherited from a single parent, who may or may not display similar characteristics.

Regarding the eye, color abnormalities come in three forms; heterochromia multiple colorsbilateral isohypochromia pale blue eyesor fundus reflective pigmentary alterations spottiness. Laren Galloway blue eyed black child.

How and why blue eyes arose has always been something Michael ealy eye color a genetic mystery. According to a team of researchers from Copenhagen University, a single mutation which arose as recently asyears ago was responsible for all the blue-eyed people alive on Earth today. The team, whose research is published in the journal Human Genetics, identified a single mutation in a gene called OCA2, which arose by chance somewhere around the northwest coasts of the Black Sea in one single Michael ealy eye color, about 8, years ago.

And most people still do. The finding that a rare mutation, probably dispersed in the rapid wave of colonisation that followed the end of the last ice age, highlights one of the great mysteries of human evolution: Those from Europe and the Near-East have many characteristics that set them apart from the rest of the human race. Not only are Europeans far more likely to have blue eyes 95 per cent in some Scandinavian countriesthey also have a far greater range of skin tones and hair colour than any other ethnic grouping.

It is only in Europe that you will find large numbers of blondes and redheads, brunettes, pale skins and olive skins, blue-eyed and green-eyed people living together in the same communities. Across the rest of the world people are almost uniformly dark-haired and dark-eyed.

Why this should Michael ealy eye color remains unknown, and in particular how such mutations can have arisen so quickly since Europe was colonised by Africans just a few tens of thousands of years ago. Another suggestion is that the strange skin, eye and hair colours seen in Europe are down to ancient interbreeding with the Neanderthals, who died out about 25, years ago. Maybe the Neanderthals were blonde or red-haired and it is their genes which we have inherited.

What Is the Origin of...

The trouble with this theory is that there is no evidence, from the scraps of Neanderthal DNA that have been recovered from bones, that there was any substantial interbreeding between them and Homo sapiens at all. Perhaps the most plausible theory is that blonde hair and blue eyes arose because of a mechanism called sex selection. The gigantic and otherwise useless tail of the peacock is the best example.

Sex selection comes to the fore when there is a lot of competition for mates of one sex or the other. The theory is that in Europe, where men had to spend weeks at a time out on the hunt, males were in very short supply. In such societies, women who had flaxen locks stood a Michael ealy eye color chance of standing out and attracting the attention of the few men that would have been available Michael ealy eye color mating.

Even back then, the blue-eyed blonde was not only in demand, but also definitely would have had more fun. Europe was not exactly colonized by Africans. Africans, especially the Khoisan of South Africa are our oldest human tribe of people, and contain the most diversity of all of us. Humans left Africa several times, once over anot 10, years ago. They lived in caves in Israel.

It is believed but some say they continued this first group of immigrants died out or returned to Africa. Then about 60, to 70, years ago another immigration began, with some groups moving out of Africa to the North and East, going Michael ealy eye color India, China, Australia eventually. They have their own particular genes that Michael ealy eye color that group.

Another group went North and West to Africa, arriving in parts of Europe perhaps 40, to 50, years ago. All humans come from African lineages, perhaps L1, L2 and L3.

As they moved out, mutations, probably climate related, began to occur, creating other lineages, the M and N groups. Many Northern Hemisphere cold Michael ealy eye color people have lighter skin, it allows them to absorb Vitamin D better. Closer to the equator, skin is darker, to protect from the sun. Whether the blue eyes of some Northern Hemisphere people from cold climates have any evolutionary value is just guessed at now.

It may just be a mutation, and may disappear. As our human lineages move away from Africa, we become less genetically diverse. Africans are more genetically diverse than those outside Africa, due to the long period of time living there. What we would recognize as modern humans originated in Africa and the oldest ones found so far are aroundyears ago. The Denisovans are a new group no one even had heard of until 5 years ago!

Red hair and light skin and eyes may also be a Neanderthal inheritance. Humans are all children Michael ealy eye color Africa; our cousins, the Neanderthals, did not come directly from Africa, and may have evolved separately perhaps for cold weather areas. Mollie brown your facts are interesting but scientifically incorrect.

How can a person with fair skin absorb melanin better then a darkskin people when darkskin people are in conjunction with the sun as opposed to have protection from the sun.

Whites suck with melanine.

They absorb better the light to produce an equal amount of vitamin D while living in the north and in the south where sun ray are oblique or even horizontal. African people need the sun of Africa for vitamin D, because their skin is a screen to avoid sunburn. Keon, I think you misread some of the article. Mollie did not say Michael ealy eye color light skin Michael ealy eye color absorb melanin better.

She said they absorb vitamin D better because they are in a climate that has less sunlight, and they need to absorb as much vitamin D from the sun as they can.

However, other scientists say that this may not be the reason for the lighter skin, as dark skin people were in Europe for a long time before their skin became lighter. And they Michael ealy eye color related to Northern Europeans. These scientists believe that it may actually be because of the change in diet which caused them to get less vitamin D from their new diet, and therefore their skin became lighter so that they could get more vitamin D from the sun. However, it is believed by scientists that Europe, Asia and the Middle East were colonized by Africans modern humans.

And maybe in these places, they occasionally interbred with the Neanderthals. But they are not all certain about that yet. Lets also put it out there, the term fair skinned is outdated and only a reminder of euro-ethnocentric white supremistic thinking.

White people burn easily and are very sun sensitive. This means the sun and all its properties like Vitamin D easily penetrate Caucasian skin: Lots of Vitamin D in white people who live where they need it — in the way way north. Anyway, why does the writer here only make mention of men noticing blonde women? Women had a hand in choosing who they procreated with; they were able to select just like most female animals are.

Stop acting like women are just some prize to be hunted with no agency or desires of their own. Me, your facts are silly.

Neanderthals have never lived in Africa. They lived in Europe and Asia.

As we live in the northern part om the world where the sun is out and strong only during summer for the most part, everyone get a D-vitamin deficiency.

So darked people are even more likely to get depressions. The lack of sun is also the reason for the flue at wintertime. It is also a something that keeps dark people safer in the sun and lets white people get burned. And the other way around in summer to avoid sun burn for white people. One does not absorb melanin. Melanin is something that the human body produces to protect itself from the harmful rays Michael ealy eye color the syn.

It is what causes the pigmentation of your skin. How much melanin your body has is decided by genetics.

Just like your hair or eye color. Actually the sun gives off vitamin D naturally. The human body absorbs vitamin D from the sun through the eyes and through the skin.

The lighter the skin and eyes the more vitamin D can be absorbed. The darker the eyes the less Vitamin D is adsorbed. There have been studies done where scientists have people of fair skin move and live in sunny places and those fair skinned people had their skin darken as a result. During other studies scientists have had Michael ealy eye color skinned people move to dark areas where there is less sun Michael ealy eye color and their skin would lighten up because they no longer needed a darker pigmentation to protect themselves from the sun as most of the time it would be covered by clouds.

Obviously the changes in skin tone were only slight. But humans like all life on Earth evolve and adapt daily in small and invisible ways.

Regarding the eye, color abnormalities...

For example red heads who have some of the fairest skin that I have ever seen actually produce their own vitamin D because their countries have so little sunlight. I know first hand because i have brown skin and i have to take citamin D, and my doctor told me that Michael ealy eye color is very common for brown skin and darker skin people to be vitamin d deficient. Keon, I think it is you that will need to check your fights. Dark skinned people who live far from the equator are vulnerable to having insufficient Vitamin D production.
