Primatologist Cleve Hicks leads a research team that has discovered a new tool-using chimp culture in the Democratic Republic of the Congo. After 12 years of research, their findings include an entirely new chimpanzee tool kit featuring four different kinds of tools. These chimps also build ground nests, which is highly unusual for any group of chimps, but especially for ones living around dangerous predators like lions and leopards. But these chimps’ novel use of tools and ground nesting aren’t even the most interesting behavioral quirks this group displays, Hicks says on this podcast.
