Post-Columbian Evolution – Holes

At this point, we have some decent examples of post-Columbian evolution, genetic changes in New World populations after 1492. There is evidence for selection for increased fertility in Quebec, along with increased mutational load due to relaxed selection. Something similar … Continue reading

People are doing GWAS studies on alleles that influence educational achievement – IQ alleles, more or less – and are finding some. Once you find them, the natural question is how the frequencies of those vary in different populations. Do … Continue reading
