To Reveal the Rhythmic Roots of Laughter, Just Tickle an Ape
Recent research links human laughter to a 15-million-year-old evolutionary lineage shared with great apes.
Answered
How long have humans and great apes shared these laughter patterns?
According to the study, the shared laughter lineage dates back 15 million years.
What is the primary significance of this research?
The study suggests that studying these rhythmic roots provides a window into the evolution of human language.
How was the laughter observed?
Coverage notes that the study involved tickling apes to observe their vocal responses.
Where it stands
A new study indicates that humans and great apes share similar vocal patterns during laughter. These rhythmic vocalizations suggest that the mechanics of giggling originated millions of years ago, establishing a common evolutionary root for the behavior.
Coverage from AP News, The New York Times, Popular Science, The Elkhart Truth, and Yahoo emphasizes the long-term consistency of these sounds. Outlets highlight how the comparative study of ape laughter provides insight into the history and development of human language.
Future reports will determine how these specific findings impact broader understandings of primate social behavior. Coverage does not yet specify the next steps for follow-up studies regarding non-vocal evolutionary markers.
