What a tease! Great apes pull hair and poke each other for fun

 

"The animals’ shenanigans hint that mischievous play evolved well before Homo sapiens did.

Young apes get a kick out of teasing each other and joking around when they’re relaxed, just like humans do.

Isabelle Laumer at the University of California, Los Angeles, and her colleagues recorded videos of five great-ape species — orangutans (Pongo abelli), chimpanzees (Pan troglodytes), bonobos (Pan paniscus), western gorillas (Gorilla gorilla) and eastern gorillas (Gorilla beringei) — as they played at zoos in San Diego, California, and Leipzig, Germany. They noted the primates’ interactions, including how often they tried to provoke a response from one another rather than simply playing together.

Like bored siblings in the back seat of a car, the apes would poke their targets repeatedly, dangle objects in their faces, pull their hair or stare at them until they responded. All five species seemed to tease each other in similar ways, and were most likely to play in this way when relaxed. The researchers say that this kind of play probably evolved at least 13 million years ago, before humans’ ancestors separated from those of these ape species." [1]
