According to an article online in the New York Times, scientists from the Beijing Genomics Institute report that Tibetans evolved a set of genes that have helped them breathe at altitudes where oxygen levels are low. They say their studies of local human genomes indicate that natural selection chose the advantageous genes as recently as 3,000 years ago.
