Pointing and pantomime are important components of human communication but so far evidence for referential communication in animals is limited. Observations made by researchers Pamela Heidi Douglas and Liza Moscovice of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, make important contributions to this research topic: To solve social conflicts female bonobos invite other females to engage in a socio-sexual behaviour by using pointing gestures and mimicking hip swings.
