Spreading Genetics

The examples had been taken from the huge range of the prehistoric population, instead of the few individuals, and that they supplied the researchers with the five specific genes linked with diet and skin color.

The AAAS reported that the “present humans who were out of Africa in originally settling in Europe in about 40,000 years past are supposed to have dark skin, that became advantageous when it is a sunny latitude. And the new facts confirmed that from about 8500 years ago, that those first hunter-gatherers in Luxembourg, Hungary and Spain also had dark skin and that they lacked the versions of the two genes—the SLC24A5 and the SLC45A2—that will lead to “depigmentation” which therefore results to the pale skin of the Europeans today.

The first farmers then from Near East came to Europe; they take both genes for lighter skin. Since they interbred with an indigenous hunter-gatherers, and one of the light-skin genes had swept through Europe, and so that the southern and central Europeans also started to have a lighter skin. Those other gene variants, the SLC45A2 was at its low levels until around 5800 years past when it brush up to high occurrence.”

It differed from the instances farther north. The prehistoric remains from the southern Sweden 7,700 of years ago were discovered to have these gene variants that indicate blonde hair and light skin, and the other gene, the HERC2/OCA2, that which cause blue eyes. This denotes to the researchers that the prehistoric hunter-gatherers of the northern Europe were blue-eyed and pale already. The light skin trait could have been beneficial in the areas of less sunlight.
