Alien Hybrid or Starchild? Those are the two potential classifications of this kid?

I wonder if this is caused by the same mutation which appeared 6000 to 10000 years ago in what is now northern Romania and which is responsible for the widespread occurrence of blue eyes in Europeans. I also wonder if these ancient Europeans had better night vision, which could be an advantage during the dark winter months.
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.
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.
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.

Actually, the secret is that they see "differently"
Here is what I mean. In World War II, our army came out with a new secret weapon - night vision. They used an infrared searchlight to light up the target and with the infrared goggles on, our fellows could see their targets.
The problem was that many of the Germans who were blond-haired and blue eyed, could see the infrared lights as soon as they were turned on and did some shooting of their own.
The answer -we experimented with this back in my college physics classes -is that one can see further into the infrared, and the other can see further into the ultra-violet. In college we looked into calibrated spectrographs and noted down the Angstrom ranges we could see, then compared them with others from all the classes. There were variations, of course, but basically everyone could see the "normal" range, but your eye color determines (or more properly reflects or absorbs) the "center" of the range you can see. In the blue eye, apparently blue is being reflected back and reds come through. The brown eye (which has a strong red component) is reflecting reds away and allowing more of the blue end of the spectrum.
I know this sounds like it doesn't make sence, since the iris is not the part where the light comes through, but it was explained to us that the color of the iris is not just from the material itself, but the light bandpass for that particular eye, which is reflected as a visible effect by the iris.
My eyes are green and I seem to have at least some of the ability shown by blue-eyed people. I can see a little ways into the infrared range, but not as far as some of my blue-eyed classmates. People (with brown eyes) have ask me what it looks like, but I can't answer that. How would you describe a color to a blind person or a person who is color-blind. All I can say is that I see it and that it looks different from red. It is the same problem they have describing to me what ultraviolet looks like. Some people (like myself) see ultraviolet bulbs 'glowing' while others are practically blinded by them. It is the same with infrared lights.
[Any of you old enough to remember the UV lights they used a lot in discotheques? What did you see when you were in one of those places?]
Anyway, I hope that clears up the question. It is not a question of seeing “better”, but what your “range” of seeing is
