Geography And History Shape Genetic Differences In Humans

ScienceDaily (2009-06-07) -- 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 distribution of genetic variations in populations around the world.
