Dr. Kirsty Graham from the University of St. Andrews discusses how bonobos use gestures to communicate, which winds into a chat about what that means for ape communication generally -- especially humans. They also have some insights into field research. Listener discretion advised: Bonobo behavior is discussed in this episode, which includes sexual habits.
