The UMMAA Brown Bag Lecture Series is pleased to present a lecture by Dr. Yuchao Zhao, assistant curator of East Asian anthropology, Field Museum of Natural History, Chicago. The lecture, "The Human Odyssey on the Roof of the World: Adaptations and Resilience on the Tibetan Plateau," will be held on Friday, October 23, 12-1 pm in Room 1322 in the School of Education Building on central campus.
The Tibetan Plateau—often described as the “Roof of the World”—represents one of the most extreme environments ever inhabited by humans. With an average elevation exceeding 4000 meters, the region poses formidable challenges including hypoxia, harsh climate, and highly variable ecological productivity. Understanding how and when humans successfully adapted to these conditions remains a central question in high-altitude archaeology. This talk synthesizes recent archaeological, paleoenvironmental, and genetic research to reassess the long-term history of human occupation on the Tibetan Plateau. Evidence from Paleolithic sites indicates that foraging populations began exploring the plateau margins as early as the Middle Pleistocene, with increasing evidence for sustained human presence during the Late Pleistocene and early Holocene. Rather than viewing the plateau as permanently settled only after the arrival of agriculture and pastoralism, new research suggests that indigenous foragers played a crucial role in establishing viable lifeways in high-altitude environments.
The Museum's Brown Bag Lecture Series is free and open to the public.
