Natural selection was hard at work changing the human body over the last few million years, and much of that selection was driven by the challenges of being a mom. I will present a brief review of the evolution of the human female body, focusing on how natural selection helped mothers cope with the biomechanical demands of being a pregnant biped, with carrying infants and food over long distances, and with giving birth to large-brained babies."
Dr. Daniel Lieberman is a Professor of Anthropology at Harvard University and Chair of the Biological Anthropology Department, while also serving on the Curatorial Board of the Peabody Museum. Dr. Lieberman is recognized as a leading expert on morphology and is especially interested in when, how and why early hominins first became bipeds, and then became so exceptional as long distance endurance runners. He is a member of the Leakey Foundation Scientific Executive Committee.
Harvard Anthropology Professor Daniel Lieberman postulates why human mothers give birth to such large babies. He argues that we live in a new energetic paradigm where the body can gestate the fetus for much longer than other primates.
