Two chimps, Sherman and Austin, learned, with extensive training, to communicate by way of keyboards in a cooperative effort to use simple tools to get food. The two inside researchers wear earphones playing loud music to reduce the chance they can give Kanzi any clues.
Duane Rumbaugh summarizes the results: But although the trained apes often used two or three signs or symbols in a sequence, and could clearly get a message across—most often a request for food or attention—researchers wondered if the apes had learned Language with a capital L.

The tokens were chosen to be completely different in appearance from the referents. And Ohio University psychologist Patrick Drumm is trying to figure out what he's saying.

Some see these differences are seen as making bonobos more like humans. Coby watches, keeping one eye on the enticing jug of cold water, and then signs again, "eat.
InSavage-Rumbaugh spent two months studying bonobos at a research station operated by Takayoshi Kano, a Japanese primate researcher in the Congo forest.
