Are humans the only animals that practice medicine? In this episode, two scientists share surprising observations of orangutans and chimpanzees treating wounds–their own and others'–with plants and insects. These discoveries challenge ideas about uniquely human behaviors and offer insights into animal intelligence, empathy, and the evolutionary roots of medicine.
