Spreading Genetics

We sort of know all this, but what is important is that white skin  and blue eyes gained an advantage that encouraged rapid intermarriage.  This led to a huge expansion of that particular variation throughout perhaps a third of the global population.  By that i mean that plausibly a third of the population may have Caucasian genetics as part of their blend. 

That advantage is still observed and is actually likely to sustained.  Caucasian culture has been dominant and available globally for only a short time and this allows for mixed marriages with all other identifiable groups to the disadvantage of any two other choices.  This looks to be a small thing but the quickest way to join into the dominant culture is as a grandchild retaining a quarter of the genetics of a grandparent. This process substantially absorbed the Eastern native population and is slowly absorbing small ethnic groups everywhere anyway today.

In this manner a dominant culture genetically absorbs multiple hybrid strains preferentially to any minority group..

Spreading Genetics 

Over a hundred pyramids have been found in China that the ancient rulers stated were ancient white skinned alien gods who had blonde hair and blue eyes. These visitors apparently came to Europe. 
Similar pyramids have been found in Mexico and Peru. The pyramids possess advanced technology that had the ability to move and carve large stones. A similar race can be found in Egypt and Sumaria who were the pharaohs and priests in ancient times. Many ancient writings claim our ancestors came from space. 

Danish researchers have concluded that all blue-eyed people share a common ancestor, presumably someone who lived 6,000 to 10,000 years ago. Blue eyes are a recessive gene to some extent. The genetics of eye color are complicated, and color is determined by multiple genes. So a mutation is unlikely the cause. There are blue eyed people in Asia and particularly Europe. 

Assuming the first blue-eyed humans was among the proto-Indo-Europeans who subsequently spread agriculture into Western Europe and later rode horses into Iran and India.

In humans, dark hair is a dominant trait; if one parent contributes a gene for dark hair and the other contributes a gene for light hair, the child will have dark hair. 

White Skin Developed in Europe Only As Recently as 8,000 Years Ago Say Anthropologists 

Humans in Europe 8,000 Years Ago had dark skin Say Anthropologists dramatic evidence suggests modern Europeans do not appear as their long ancient ancestors did. 

The myriad of skin tones and eye colors that humans express around the world are interesting and wonderful in their variety. Research continues on how humans acquired the traits they now have and when, in order to complete the puzzle that is our ancient human history. Now, a recent analysis by anthropologists suggests that the light skin color and the tallness associated with European genetics are relatively recent traits to the continent. The samples are derived from a wide range of ancient populations, rather than a few individuals, and they supplied researchers with five specific genes associated with skin color and diet. AAAS reports that the “modern humans who came out of Africa to originally settle Europe about 40,000 years are presumed to have had dark skin, which is advantageous in sunny latitudes. And the new data confirm that about 8500 years ago, early hunter-gatherers in Spain, Luxembourg, and Hungary also had darker skin: They lacked versions of two genes—SLC24A5 and SLC45A2—that lead to depigmentation and, therefore, pale skin in Europeans today. This dramatic evidence suggests modern Europeans do not appear as their long ancient ancestors did. 

Then, the first farmers from the Near East arrived in Europe; they carried both genes for light skin. As they interbred with the indigenous hunter-gatherers, one of their light-skin genes swept through Europe, so that central and southern Europeans also began to have lighter skin. The other gene variant, SLC45A2, was at low levels until about 5800 years ago when it swept up to high frequency.”

An international team of researchers as headed by Harvard University’s Dr. Iain Mathieson put forth a study at the 84th annual meeting of the American Association of Physical Anthropologists recently stated. 

Based on 83 human samples from Holocene Europe as analyzed under the 1000 Genomes Project, it is now found that for the majority of the time that humans have lived in Europe, the people had dark skin, and the genes signifying light skin only appear within the past 8,000 years. This recent and relatively quick process of natural selection suggests to researchers that the traits which spread rapidly were advantageous within that environment, according to the American Association for the Advancement of Science (AAAS).
