New Harvard study on natural selection in West Eurasia (Europe and the Near East) over the last 14,000 years.

"[We] identify selection for combinations of alleles that are today associated with lighter skin color, lower risk for schizophrenia and bipolar disease, slower health decline, and increased measures related to cognitive performance (scores on intelligence tests, household income, and years of schooling)... The polygenic score today predictive of body fat percentage [decreased] by around a standard deviation over ten millennia."
