A study identifies 5 genetic markers near the EGLN1 gene that are associated with increased aerobic capacity at altitude and were found at higher frequency among 429 high-altitude Quechua people of Peru than in 94 people from lowland populations; the gene encodes a protein that controls the cellular hypoxic response, suggesting that the markers might represent evidence of natural selection in high-altitude populations.
