The Menopause Mystery

This Radiolab episode, hosted by Molly Webster and featuring Heather Radke, explores the science and evolutionary puzzle of menopause. The episode begins with Lucy Cooke's investigation into menopause in killer whales, guided by Dr. Deborah Giles' poop sample analysis. The discussion expands to include insights from scientist Kevin Langergraber on chimpanzee menopause and the "grandmother hypothesis," which suggests post-menopausal females contribute to their grand offspring's survival. The episode further explores the "reproductive conflict hypothesis" in chimpanzees, suggesting older females may cease reproduction to benefit the group's overall genetic success. Finally, the episode features Caroline Paul, who shares her personal experiences with menopause and advocates for embracing new adventures and possibilities in post-menopausal life, challenging the negative cultural narratives surrounding aging women.
