New Thoughts on Possible Hominin Communication

Chimp bonobo gesturesYORK, ENGLAND—Chimpanzees and bonobos both have repertoires of gestures that convey meaning to other members of their species. According to a report in Science Magazine, researchers led by Kirsty Graham of the University of York have concluded that about 90 percent of these gestures overlap between species and therefore were probably inherited. It is possible the apes developed the gestures independently, but the high correspondence suggests this is unlikely. Graham speculates that when humans see these gestures, many of them will also understand the meaning conveyed, suggesting the signals may have been passed down from the apes’ last common ancestor with modern humans. Further research will test how the gestures develop over an ape’s lifetime, and see whether people share any of the gestures. For more, go to “No Changeups on the Savannah.”
