Oo oo, ha ha: why humans and great apes giggle alike when tickled

Nature NewsIndependentCenter11 days ago

Research indicates that humans and great apes share similar rhythmic patterns in their laughter when tickled, suggesting that vocal motor control may have evolved from a common ancestor. This finding could provide insights into both the evolution of laughter and human speech. Additionally, a study reveals that green sea turtles use Earth's geomagnetic field for navigation but only with approximate accuracy, often taking indirect paths to reach their destinations. Meanwhile, scientists are developing 3D-printed skin technologies aimed at reducing scarring after burns.

A study published in Communications Biology analyzed the laughter patterns of great apes and human children when tickled, finding that both groups produced similar rhythmic patterns of laughter with evenly spaced intervals between sounds. The research included recordings from four species—chimpanzees, bonobos, gorillas, and orangutans—as well as human children aged between six months and seven years. The study suggests that this rhythmic pattern may be a trait inherited from a common ancestor shared by humans and great apes around 15 million years ago. Researchers noted that while tickled laughter showed consistency, laughter during social play exhibited more variability due to physical movement affecting breathing patterns.
