The University of New Mexico Department of Anthropology Colloquium Series presents “Corn, Calories, Labor, Risks and Outcomes” Thursday, Sept. 11 at 4 p.m. in Hibben Hall, room 105, with anthropologist, David E. Stuart.

Stuart will discuss the impressive growth in population size and cultural complexity among the Four Corners prehistoric farming peoples between roughly 250 and 900 Common Era (CE), which established the platform to support an even more complex regional society usually referred to as the “Chaco Phenomenon.” That expansive society prospered from about 900 CE to early 1100 CE, before fragmenting.

Based on his, and his undergraduate students’ research, Stuart talks about energy, calories, crop yields, weather patterns and biological data as clues to underlying evolutionary patterns in prehistory with modern parallels. He argues that such clues, though several are archaeologically unconventional, merit further research.

Stuart is an American anthropologist, novelist and associate provost emeritus at UNM. He graduated from West Virginia Wesleyan College, with a B.A. in Anthropology and Sociology in 1967, and from UNM with an M.A. in 1970 and Ph.D. in 1972 in Anthropology.

The event is free and open to the public. For more information call (505) 277-1400.
