The article discusses the research conducted by researchers P. Jeffrey Brantingham and colleagues, author of "Qinghai-Tibet," on how prehistoric population adapted to extreme environmental conditions of Tibetan Plateau in Tibet, China. Living at high elevations human populations confronts with unique challenges such as severe cold and wind, lower oxygen levels, limited resources, and physiological risks including increased nutritional needs, diminished work capacity, and reduced fertility. The author of this article comments that the area is currently inhabited by nomadic pastoralists, this work suggests that other adaptive strategies are possible. |
