Origin Stories is The Leakey Foundation’s award-winning podcast about how we became human.
Episode 54: The Obstetrical Dilemma
The widely-held idea known as the “obstetrical dilemma” suggests that babies are born early so their big brains can fit through the mother’s pelvis, which can’t get any wider due to our method of bipedal locomotion. On this episode, Leakey Foundation grantees Dr. Holly Dunsworth and Dr. Anna Warrener describe their search for the evidence behind the obstetrical dilemma and they discuss the importance of the stories we tell about our bodies.
Episode 53: Sleep and the Moon
Sleep is one of the defining traits of human life. It’s also one of the most mysterious. Dr. Horacio de la Iglesia is a neurobiologist who’s on a quest to understand how patterns of human sleep evolved. His new research shows an unexpected connection between sleep and the cycles of the moon.
