"Great Apes: Masters of Teasing and Humor, Study Reveals"

A study has found that great apes, including chimpanzees, bonobos, gorillas, and orangutans, engage in playful teasing behavior similar to humans, with the intention of provoking a response or attracting attention. The research suggests that this behavior may have evolved in human ancestors around 13 million years ago. By analyzing videos of juvenile apes engaging in teasing behaviors, the study provides insights into the evolutionary origins of playful teasing and its cognitive prerequisites.
