Scientists tickled monkeys to find if they have the same giggles as humans — and they do

Scientists recently tickled monkeys to explore if these primates share the same laughter traits as humans, and the results showed they do indeed giggle. This study suggests that laughter has been a part of our evolutionary history for at least 15 million years, hinting at a deep connection between humans and other great apes. The findings are significant because they provide insight into the origins of human laughter and social bonding behaviors, showing that laughter might be a universal trait among primates. This research could help us better understand the evolutionary roots of our own behaviors and social interactions.
