About

Dr. Randy Haas is an archaeologist and assistant professor of anthropology. He earned his Ph.D. from The University of Arizona in 2014. Prior to joining the UC Davis faculty in 2017, he was a postdoctoral research associate at the Universities of Maryland and Wyoming. 

Research Focus

Dr. Haas studies the evolution of complex human behaviors among ancient forager societies. For some 200 thousand years prior to the advent of market and agricultural economies, forager economies were the only human economies on the planet. Dr. Haas uses the archaeological record and quantitative methods to understand how our biology, cultures, and social organization evolved in those forager contexts. His recent work is advancing our understanding of how early hunter-gatherers of the Andes Mountains adapted to physically challenging alpine environments above 3800 meters in altitude and how cooperative social structures, potato and quinoa agriculture, and alpaca husbandry evolved between 12,000 and 3500 years ago.
