Cynthia Beall is an American physical anthropologist at the Case Western Reserve University, Cleveland, Ohio.
Four decades of her research on people living in extremely high mountains became the frontier in understanding human evolution and high-altitude adaptation.
Her groundbreaking works among the Andean, Tibetan and East African highlanders are the basis of our knowledge on adaptation to hypoxic condition and how it influences the evolutionary selection in modern humans.
[3] Cynthia Beall is the leading scientist in the study of high-altitude adaptation in humans, particularly in places where there is little air to breathe.
[1][7] Physiological conditions such as resting ventilation, hypoxic ventilatory response, oxygen saturation, and haemoglobin concentration are significantly different between the Tibetans and the Aymaras.
