Dr. Cynthia Beall, Distinguished University Professor and S. Idell Pyle Professor of Anthropology at Case Western Reserve University, will give a presentation on â€œTibetan Adaptation to High Altitude.â€ Dr. Beall is a physical anthropologist whose research focuses on human adaptation to high-altitude hypoxia, as well as the genetics of adaptive traits and evidence for natural selection. This free public lecture will be followed by a reception.
High-altitude environments are natural laboratories for testing hypotheses about human evolution and adaptation. Indigenous populations have resided for millennia on the Tibetan, Andean and East African plateaus. Tibetans differ from lowlanders at altitude and from other high-altitude populations in nearly every trait examined. This talk will describe the unique biology of high-altitude native Tibetans and present evidence supporting the hypothesis that they represent the outcome of natural selection on traits with heritable variation.
