Congratulations to UMMAA alum Yuchao Zhao, UMMAA curator Brian Stewart, and their colleague Michael Obie from the University of Toronto, who have published a paper in Quaternary Science Reviews.

The title of their paper is "The archaeology of human permanency on the Tibetan plateau: a critical review and assessment of current models.” Their work reviews recent archaeological and genetic research on the peopling of the Tibetan Plateau and presents the results of new least cost path modeling. They ultimately suggest that hunter-gatherers sustained year-round occupations in the Plateau's interior during the Pleistocene and early Holocene, and that the emergence of domestication played a significant role in promoting the large-scale peopling of high altitudes.
