Researchers have long used birdsong as a prime example when studying the complexities of speech. But a new study based on orangutans attempts to change that and shed some light on how humans acquired the ability to make more than one vocal sound at a time.
The researchers spent a massive amount of time observing and recording the great apes in the wild – some 3,800 hours in Borneo and Sumatra within range of the animals. What they found connects present-day beatboxing sounds to early human language.
