Some of the chimps' gestures, the researchers say, are unambiguous - used consistently to convey one meaning. "The vagueness of the gesture meanings suggest either that the chimps have little to communicate, or we are still missing a lot of the information contained in their gestures and actions," she said.

The frequently used play gestures were shorter in length than less frequently used gestures. "The big message [from this study] is that there is another species out there that is meaningful in its communication, so that's not unique to humans," said Dr Hobaiter.
