Originally Published 1 year ago — by CNN
A new study has found that great apes, including orangutans, chimpanzees, bonobos, and gorillas, exhibit playful teasing behavior similar to humans, involving provocative and surprising actions. Researchers analyzed video footage of spontaneous social interactions between apes and identified 18 different teasing behaviors, such as poking and hindering movement. The study suggests that the prerequisites for humor evolved in the human lineage at least 13 million years ago and aims to investigate the function of teasing in apes and the evolution of humor in other primates and large-brained animals.
