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.
