Scientists, however, have not found a strong signal for this “high-altitude gene” in the genomes of Indigenous people living in the Andes Mountains of South America. It’s been less clear how people adapted to the altitudes greater than 2,500 meters in the Andean highlands, where low-oxygen levels, frigid temperatures and intense ultraviolet radiation make life challenging in the extreme.
A study led by anthropologists at Emory University took a new approach to explore this Andean mystery.
