The secret communication of gibbons has been interpreted for the first time in a study published in the open access journal BMC Evolutionary Biology. The research reveals the likely meaning of a number of distinct gibbon whispers, or ‘hoo’ calls, responding to particular events and types of predator, and could provide clues on the evolution of human speech. Esther Clarke is lead author of the research and a Research Fellow in the Department of Anthropology at Durham University.
