The question of its origins and how it evolved is one of the most intractable in all science.

One of the dominant theories in this field associates the possibility of producing differentiated sounds, the basis of spoken communication, with the "descent of the larynx" observed over the course of the evolution of Homo sapiens.

More generally, spoken languages may have evolved from ancient articulatory skills already possessed by our last common ancestor , around 25 million years ago.

This research was conducted thanks to close collaboration between many specialists from the Gipsa-Lab (CNRS/Grenoble INP/Grenoble Alpes University), the Laboratory of Cognitive Psychology (CNRS/AMU), the Laboratory of Anatomy at the University of Montpellier, the Speech and Language Laboratory (CNRS/AMU), and New College, University of Alabama.

Published in on January 11, 2017, the data confirm that baboons are capable of producing at least five vocalizations with the properties of vowels, in spite of their high larynx, and that they are capable of combining them when they communicate with their partners.

The investigators found that lemurs use vocalizations far more selectively than previously thought, ...

If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file.

The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.

The vocalizations of baboons thus point to a system of speech among non-human primates.

Baboons produce vocalizations comparable to vowels. This is what has been demonstrated by an international team coordinated by researchers from the Gipsa-Lab (CNRS/Grenoble INP/Grenoble Alpes University), the Laboratory of Cognitive Psychology (CNRS/AMU), and the Laboratory of Anatomy at the University of Montpellier, using acoustic analyses of vocalizations coupled with an anatomical study of the tongue muscles and the modeling of the acoustic potential of the vocal tract in monkeys.
