Great ape laughter reveals a hidden origin of human speech

Scientists have discovered that the rhythm of human laughter shares deep evolutionary connections with great apes like chimpanzees, bonobos, gorillas, and orangutans. This shared pattern could provide significant insights into how the complex vocal control required for human speech developed over time. Understanding these origins could shed light on the fundamental aspects of human communication and our evolutionary past, suggesting that our ability to laugh and speak may have emerged from a common ancestor.
