Great ape laughter reveals a hidden origin of human speech
Researchers from the University of Warwick have discovered that the rhythmic structure of laughter in great apes has remained consistent for 15 million years. This shared vocal pattern provides a unique evolutionary link that may help explain the origins of human speech.
Why it matters
Understanding the evolutionary roots of laughter offers scientists a rare, non-fossilized window into the development of complex human communication.
A new study from the University of Warwick suggests that the rhythm of human laughter has remained surprisingly consistent for at least 15 million years. By comparing the laughter of humans and other great apes, researchers uncovered evidence that this ancient vocal pattern may offer valuable clues about how human speech gradually evolved.
The report is based on scientific findings and presents the study's conclusions objectively.
