Humans and great apes show similar rhythmic pattern in laughter

Although laughter is often perceived as a uniquely human trait, research indicates otherwise. Scientists have conducted a comparative analysis of laughter patterns between humans and several great ape species, specifically chimpanzees, bonobos, gorillas, and orangutans. The findings reveal that these different species exhibit similar rhythmic patterns when laughing, demonstrating that the fundamental nature of this vocal expression is shared between humans and their closest primate relatives across these diverse groups.
