Dr. Anna Warrener is an assistant professor in the Anthropology department at University of Colorado Denver. Her research focuses on the evolution of the human musculoskeletal system using biomechanical techniques to assess how variation in physical structure affects locomotor performance. She is specifically interested in the human pelvis and how its unique anatomy impacts both locomotion and human birth.

In this episode, we talk about human bipedalism, the human pelvis, and childbirth. We start by talking about the major steps we took to evolve our modern human anatomy, starting with our last common ancestor with chimps and bonobos. We discuss how our pelvis had to evolve for us to become bipedal. We go through the major hypothesis out there to explain the evolution of human bipedalism. We discuss the relationship between human life history, brain size, and the evolution of the female pelvis. We ask to what extent childbirth for human females is problematic from an evolutionary perspective. We talk about sex differences on the level of the pelvis. We also talk about human altriciality, and timing of birth.
