Scientists have used recordings of modern day apes being tickled in order to trace the origins of laughter back over 10 million years to the last common ancestor humans shared with them.
The first hoots of laughter from an ancient ancestor of humans rippled across the land at least 10 million years ago, according to a study of giggling primates. Researchers used recordings of apes and babies being tickled to trace the origins of laughter back to the last common ancestor that humans shared with the modern great apes, which include chimpanzees, gorillas and orang-utans."
