New research finds that it is not only human babies who love to playfully tease each other. Researchers reasoned that since language is not required for this behaviour, similar kinds of playful teasing might be present in non-human animals. Now cognitive biologists and primatologists have documented playful teasing in four species of great apes. Like joking behaviour in humans, ape teasing is provocative, persistent, and includes elements of surprise and play. Because all four great ape species used playful teasing, it is likely that the prerequisites for humour evolved in the human lineage at least 13 million years ago.
