Humans and Apes Share Ancient Laughing Trait
Phys.org1 min read95 words
A new study indicates that the vocalizations underlying human laughter and great ape giggling share a common evolutionary origin, tracing back to the divergence of the two lineages on the primate family tree. Researchers analyzing acoustic recordings and behavioral contexts found that both humans and great apes produce these sounds through remarkably similar physiological mechanisms, suggesting that the neural pathways governing laughter were established in a shared ancestor millions of years ago.
The investigation compared spontaneous vocalizations across multiple great ape species, including chimpanzees, bonobos, and orangutans, with human laughter elicited during comparable social interactions
