Laughter's steady rhythm traces the evolution from apes to human speech

A cross-species study of laughter in orangutans, gorillas, bonobos, chimpanzees, and humans finds laughter isochronous across extant great apes, with tempo accelerating and variability increasing over roughly 15 million years of hominid evolution. Tickling-induced laughter is more regular than play, and humans show the most context-sensitive tempo changes, indicating progressive gains in vocal control that likely paved the way for speech and language.

Orangutans' Dual Sounds Provide Insight into Human Speech Evolution

Orangutans have been observed producing two different sounds simultaneously, similar to human beatboxers or songbirds. The discovery suggests that the early language structure of our ancestors might have resembled something like beatboxing. The vocal control abilities of great apes have been underestimated compared to the focus on bird vocal abilities. The findings provide clues around the evolution of human speech and beatboxing capabilities.
