Geography and history shape genetic differences in humans
New research indicates that natural selection may shape the human genome much more slowly than previously thought. Other factors -- the movements of humans within and among continents, the expansions and contractions of populations, and the vagaries of genetic chance have heavily influenced the d...Penn Medicine honored for its historic role in the history of microbiology
