The next time you burst into laughter, you might be sharing something with ancestors that lived millions of years ago. A new study suggests the rhythm behind human laughter has endured far longer than anyone imagined. By comparing humans with great apes, researchers believe they have uncovered an ancient link to the origins of speech. The findings offer a rare glimpse into how vocal communication evolved long before language existed, as per a report by Science Daily.
The sound of human laughter may carry a much older story than most people realize. According to new research from the University of Warwick, the rhythm that underpins the way people laugh today appears to have been shared by great apes for roughly 15 million years.
