This week on the Sausage of Science, Chris and Cara chat with Dr. Alice Yao, an Associate Professor in the Department of Anthropology at the University of Chicago. They discuss Dr. Yao’s archaeological work exploring how genetic markers have been (mis)applied to assess the evolution of lactase persistence. This work has important implications for how lactase persistence is talked about in the current political climate.
