It’s long been known that chimpanzees “speak” in both sounds and gestures. But now, scientists have shown that different groups of chimpanzees speak at different rates. Kanyawara chimpanzees from Uganda’s Kibale National Park, for example, speak in rapid-fire and interrupt each other frequently, much like Americans. The Sonso chimpanzees from the Budongo Forest, also in Uganda, speak more slowly, like the Danes. Hosts Marco Werman and Carolyn Beeler explain.
