Hour 2: How do we define “normal” when it comes to women’s health and how might the study of early humans and even precursor species help our understanding? We’ll spend this hour with Wenda Trevathan, Professor Emerita of Anthropology at New Mexico State University and author of “Ancient Bodies, Modern Lives: How Evolution Has Shaped Women’s Health” (Oxford University Press, 2010). She’ll deliver the annual Ben and Trudy Termini Distinguished Anthropologist Lecture this evening at the University of Texas at Arlington.
