United KingdomA new study suggests that humans and great apes have shared similar laughter patterns for at least 15 million years, indicating a possible evolutionary link. Researchers analyzed recordings of 13 captive apes, including gorillas, orangutans, chimpanzees, and bonobos, which were previously collected over decades. They compared these recordings with new audio captures of children laughing during play and tickling. The study found that both human and ape laughter share rhythmic similarities, suggesting a common ancestral trait. The research was conducted by primatologist Chiara De Gregorio and published in the journal *Communications Biology*. The findings highlight the potential for understanding human communication through comparative analysis of animal vocalizations.
