The genetics of Mexico recapitulates Native American substructure and affects biomedical traits

[Population] genetics of Mexico by @cdbustamante lab
http://www.sciencemag.org/content/344/6189/1280.abstract Has groups as divergent from each other as Europeans v Asians

QT:{{”
We found striking genetic stratification among indigenous populations within Mexico at varying degrees of geographic isolation. Some groups were as differentiated as Europeans are from East Asians.
Pre-Columbian genetic substructure is recapitulated in the indigenous ancestry of admixed mestizo individuals across the country.

The genetics of indigenous Mexicans exhibit substantial geographical structure, some as divergent from each other as are existing populations of Europeans and Asians.

QT:{{”
Recent rapid growth of human populations predicts that a large number of genetic variants in populations today are very rare, i.e., appear in a small number of individuals. This effect is similar to that of purifying selection, which drives deleterious alleles to become rarer. “}}

Analysis of 6,515 exomes reveals the recent origin of most human protein-coding variants : Nature : Nature Publishing Group

QT:”
We estimate that approximately 73% of all protein-coding SNVs and approximately 86% of SNVs predicted to be deleterious arose in the past 5,000–10,000 years.
