Dark Skin and Blue Eyes: European Hunter-Gatherers Did Not Fit with Common Representations
The popular image of the light-skinned European hunter-gatherer is not correct. DNA taken from a 7,000-year-old wisdom tooth found in Spain in 2006 shows a different story. A study of the tooth shows that the man who owned it had dark hair, blue eyes, and the dark-skinned genes of an African - though scientists don’t know what the person’s exact skin tone was. The blue-eyed gene is one of the most interesting finds because it was previously believed to have been a later arriving trait brought by farmers who entered the continent more than 5,000 years ago.
The 2014 study was the first to analyze a pre-agricultural European genome. It was led by Inigo Olalde of the Institut de Biologia Evolutiva in Barcelona and published in the journal Nature – providing significant insight into the appearance of modern humans before farming arose in Europe.

The tooth came from the skeleton of a Mesolithic man who was found in a Cantabrian cave near León in northwest Spain, in 2006. This man was found alongside the skeleton of another Mesolithic man. Both died in their early 30s and their remains were well-preserved in the cave’s cool environment. The age of their bones and other artifacts found at the site, such as reindeer teeth which had holes to string them onto the men’s clothing, showed the researchers that these two men were hunter-gatherers.

It took several attempts before the team of scientists managed to recreate the full genome from the DNA of a wisdom tooth root. When they finally did, they were shocked. Dr. Carles Lalueza-Fox from the Institute of Evolutionary Biology in Barcelona explained the first of the fascinating discoveries made by the researchers:
“The biggest surprise was to discover that this individual possessed African versions of the genes that determine the light pigmentation of the current Europeans, which indicates that he had dark skin. You see a lot of reconstructions of these people hunting and gathering and they look like modern Europeans with light skin. You never see a reconstruction of a Mesolithic hunter-gatherer with dark skin”.

Following that find, the scientists were also amazed to see the man’s genes for blue eyes – an unexpected trait because it was previously believed that blue eyes were a more recent development. The presence of genetic markers for blue eyes means the Mesolithic man is the oldest example of a European with blue eyes. Dr. Lalueza-Fox said that this result was even more of a shock for the team than the Mesolithic man’s skin color, “Even more surprising was to find that he possessed the genetic variations that produce blue eyes in current Europeans, resulting in a unique phenotype [physical type] in a genome that is otherwise clearly northern European.”
A 2008 study showed that blue eyes probably began as a genetic mutation approximately 10,000 years ago. The earliest examples of this trait are believed to have arisen around the Black Sea. The 2014 study suggested that anyone who has blue eyes today has ancestors who came from the same family which first had the mutation near the Black Sea. The 2014 study’s results mean people with the gene for blue eyes made their way across Europe before agriculture took precedence over hunting and gathering. Farming is also said to have been spread from the east to the west.

No one knows for certain why blue eyes became common amongst ancient Europeans. Two possibilities are: it may have helped prevent eye disorders in the low light of European winters, or blue eyes were seen as attractive in a mate.
Finally, it’s worth noting that researchers discovered more about the Mesolithic man than just his appearance. Their findings suggest that he had an immune system similar to people living today and he was lactose intolerant. The similarity between his immune system and modern humans was also a surprise. It was previously believed that many genes for immunity also arose alongside the popularity of farming – with disease spreading more quickly in stationary settlements and close contact with animals. One suggestion for the reason hunter-gatherers may have held similar immunity genes is because they were also exposed to diseases such as cholera.

Just clone the ancient bones/dna, and let’s really see. China should lead the way.
...But if we’re going to do the analysis, let’s have a hundred samples, double-blind, using every capable lab across the globe. Then reconcile the results. And keep it TRANSPARENT, in public view, all throughout the process.
Nobody gets paid to tell the truth.
Just drinking on Sat afternoon. All these migration stories try to pinpoint one area were we all originated from. We can't forget the fact that this earth was one large land mass or continent. And we all fairly looked same were dark tan people because it was an extremely hot tropical climate. After the tectonic break up and ice age is when started to develop genetic differences based on climatic activity. Not one to promote Africa or Africans as originators, I think the same could be said about S. America. The fact that Africa was never covered with snow or extreme cold temperatures is why give them the nod. Also in terms of dark skin see alot comments that take offense dark skin people being the forerunners which is a problem. Because have to due with inferior race terminology period to get to the unbiased truth. We can no longer doubt the accomplishments Africans have had on civilization in as much as we consider Europeans to only be just hunters & gatherers. We are all human. The first civilizations were dark skinned and mixed. But I present to you exhibit "A" the Albino. Which for some reason appears the most amongst the darkest population in Africa the Sudan. Not to offend Albinos but it has always been my curiosity to see study them, and there generational offspring.

According to the Urantia Book, the old Europeans were blue-skinned people. There were eventually defeated and absorbed by the white man, who was a mixture of blue and “Andite” – the descendents of Adam.
