From: Identifying positive selection candidate loci for high-altitude adaptation in Andean populations
The geography of human adaptation to high altitude. Geographic locations where humans have adapted to life at high altitude are indicated in grey and include the Andean Altiplano of South America, the Tibetan Plateau of Central Asia and the Semien Plateau of Ethiopia. The inset indicates the sampling locations of the four Native American population samples. The populations include Peruvian Quechua, Bolivian Aymara, Nahua, Mixtec and Tlapanec speakers from Guerrero, Mexico, and Maya from the Yucatan Peninsula, Mexico.
