(Phys.org) -- A Stirling researcher has identified between 20 and 30 manual gestures used by a community of wild chimpanzees, used to communicate with others in a range of activities including nursing, feeding, sex, aggression and defence. At least a third of these gestures may be shared with humans and these similarities may help us to discover how humans evolved language.
