It is generally believed that black people do not possess blue eyes.
The blue eyes has always been associated with the Caucasians (whites).
In many scientific studies and a more recent one conducted by the
Copenhagen University the genetic mystery of "blue eyes" is said to have
originated from the northeast coast of the Black Sea.

So why are some few black people have "blue eyes' nowadays? The answer
according to scientists could only be attributed to genetic mutation
or Waardenburg syndrome (WS),which is a rare (1/40,000) disease
characterized by sensorineural deafness in association with pigmentary
anomalies and defects of neural-crest-derived tissues.

colonized Europe over 10,000 years ago and they were inf fact the first
homo sapiens to cross Europe to Asia and south pacific. Could it also
be that some blacks with blue eyes may have gotten blue eyes from their
ancient African ancestors and whites that inter-bred during Africa`s
colonization of Europe? This question has become more relevant as some
few children born of both African/100% black parents possesses "blue
eyes."

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.

Blue eyes as a Result of Wardenberg Syndrome There are four types of
Waardenburg Syndrome, with a mix of possible characteristics as the
determinant. Medical challenges increase with type. The boy in the
picture 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 42,000 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 colors), bilateral isohypochromia (pale blue
eyes), or fundus (reflective) pigmentary alterations (spottiness).

genetic blue eyes in dark skinned people, as previously discussed,
understanding Waardenburg's is another avenue of accurately recognizing
phenotype (gene expression) in eye color.

Below is a story on the origins of blue eyes :
All blue-eyed people can be traced back to one ancestor who lived 10,000 years ago near the Black Sea
By MICHAEL HANLON
Black girl with blue eyes
Everyone with blue eyes can be traced back 10,000 years to the Black
Sea region Throughout history they have been the eyes that are prized.
Frank Sinatra's were legendary, Paul Newman's melted a million hearts
while Cameron Diaz's dazzle in modern Hollywood.
But
how - and why - blue eyes arose has always been something of a genetic
mystery. Until now. According to a team of researchers from Copenhagen
University, a single mutation which arose as recently as 6-10,000 years
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 individual, about 8,000 years ago.
Actor Michael
Ealy has sky blue eyes. The gene does not "make" blue in the iris;
rather, it turns off the mechanism which produces brown melanin pigment.
"Originally, we all had brown eyes," says Dr Hans Eiberg, who led the
team. 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: the oddness of Europeans. 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 countries), they 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, blueeyed and green-eyed
people living together in the same communities. Across the rest of the
world people are almost uniformly darkhaired and dark-eyed. Why this
should be 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. One theory is that Europe's cold weather
and dark skies played a part. Fair skin is better at making Vitamin D
from the 8 per cent of the world's population have blue eyes weak
sunlight found in northern latitudes. 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 25,000 years
ago. Maybe the Neanderthals were blonde or red-haired and it is their
genes which we have inherited. 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.
Zimbawean
boy with blue eyes This is where males and females choose as their
mates those who have one unusual physical characteristic, not
necessarily associated with "fitness" per se but simply something
unusual. 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 better
chance of standing out and attracting the attention of the few men that
would have been available for mating. Even back then, the blue-eyed
blonde was not only in demand, but also definitely would have had more
fun.
