Natural Selection: People seek out their own kind

The Left's latest strategy in undermining common sense in the denial of the existence of race as a biological reality, as we are observing in Sweden -- one of the "whitest" places on Earth. Our natural reaction is anger at the absurdity of this.

But do we really need to get angry about this? Clearly this is subversive and absurd, but can their absurdity of "race is a social construct" really change anything? Sure, they'll get some weak-minded fools to believe and even repeat this nonsense. But so what? Can they really change the laws of nature, id est natural selection?

According to at least one peer-reviewed scientific study, the answer is NO. In fact, it's as if people can sniff out people that are genetically similar to themselves, often times making friendships with people who are their kin and they don't even realize it, usually around the neighborhood of 3rd to 6th cousin:

Abstract

More than any other species, humans form social ties to individuals who are neither kin nor mates, and these ties tend to be with similar people. Here, we show that this similarity extends to genotypes. Across the whole genome, friends’ genotypes at the single nucleotide polymorphism level tend to be positively correlated (homophilic). In fact, the increase in similarity relative to strangers is at the level of fourth cousins. However, certain genotypes are also negatively correlated (heterophilic) in friends. And the degree of correlation in genotypes can be used to create a “friendship score” that predicts the existence of friendship ties in a hold-out sample. A focused gene-set analysis indicates that some of the overall correlation in genotypes can be explained by specific systems; for example, an olfactory gene set is homophilic and an immune system gene set is heterophilic, suggesting that these systems may play a role in the formation or maintenance of friendship ties. Friends may be a kind of “functional kin.” Finally, homophilic genotypes exhibit significantly higher measures of positive selection, suggesting that, on average, they may yield a synergistic fitness advantage that has been helping to drive recent human evolution.

 In addition to our friendships, our marital and mating partners are also, most of the time, related to us in the realm of 3rd to 6th cousin

 Understanding the social and biological mechanisms that lead to homogamy (similar individuals marrying one another) has been a long-standing issue across many fields of scientific inquiry. Using a nationally representative sample of non-Hispanic white US adults from the Health and Retirement Study and information from 1.7 million single-nucleotide polymorphisms, we compare genetic similarity among married couples to noncoupled pairs in the population. We provide evidence for genetic assortative mating in this population but the strength of this association is substantially smaller than the strength of educational assortative mating in the same sample. Furthermore, genetic similarity explains at most 10% of the assortative mating by education levels. Results are replicated using comparable data from the Framingham Heart Study.

Humanity as a whole -- and Europeans specifically -- are surprisingly inbred due to multiple population bottlenecks. This is not necessarily a bad thing. There is plenty of genetic variation within the greater European family as it is. So this ability to sniff out our genetic relations must be an evolutionary trait thanks to natural selection.

So much for "social construct", huh?
