The Infinite Monkey Cage by BBC Radio 4

Brian Cox and Robin Ince are joined by Dr Jane Goodall DBE, comedian Bill Bailey and primatologist Dr Cat Hobaiter to find out what we've learnt in the 60 years since Jane first discovered the chimpanzees of Gombe. From tool use, to language and even to culture, her revolutionary work has transformed our understanding of our great ape cousins, and ourselves. The panel chat about how far our understanding has come in that time, and talk about their own unique close-up experiences of chimpanzees, macaques and baboons, and Bill gets a masterclass in how to speak chimp from a true expert!
