SGA study comparing laughter patterns between humans and great apes found that both share a similar rhythmic structure, suggesting this trait may date back to their common ancestor around 15 million years ago. Researchers analyzed recordings of laughter from humans, chimpanzees, bonobos, gorillas, and orangutans, noting that while all species exhibit regular intervals between sounds, human laughter is faster, more variable, and more responsive to social context. The study highlights differences in rhythmic complexity and flexibility between humans and other great apes, with humans showing greater adaptability in modifying laughter based on situational cues. These findings could provide insights into the evolutionary development of human speech and the social-emotional foundations of communication.
