Humanity's Genetic Diversity on the Decline

jd writes "In a study covering five different periods of history, from 300 AD to the present day, and geographically spread across much of Europe, scientists have extracted the mitochondrial DNA from a sizable number of individuals in an effort to examine changes in diversity. The results, published in the Royal Society journal is intriguing to say the least. 1700 years ago, three out of every four individuals belonged to a different haplotype. In modern Europe, the number is only one in three. The researchers blame a combination of plague, selection of dominant lineages and culturally-inflicted distortions. The researchers say more work needs to be done, but are unclear if this involves archaeology or experiments involving skewing the data in the local female population."

Undefined Genetic Groups bad for overall health

[JAB Creations]

With different and distinct cultural groups it gives humanity more variations on how to resist diseases and other health afflictions with varying results. One race/culture may resist one disease yet be weak to another.

The ability to travel is the biggest natural evolutionary threat of "oneness". The second biggest threat are the people who through the media continue to suggest this mixing is natural when it is not. You can see plenty of suggestive propaganda if you actually look for it such as every commercial has a black person just for the sake of "diversity" or mixed couples in women's magazines being promoted as "progressive". The people who sell this sort of propaganda of course don't value different cultures, it's "politically correct" and if we all loose our cultural distinctions we will be much weaker not only genetically (and I say that about all races) but also as groups of people in general in the future. The true racists are the ones who would prefer there to be theirs and then one giant undefined blob. From my understanding those racists are defined as cultural Marxists.

It's not that it's a "faith", per se. It's just that it's a theory based on the NON-existence of a creator.

No, it isn't, you liar.

You won't score any points with outright lies.
