Orangutans crack consonants and vowels to shed new light on the evolution of human speech

Orangutans crack consonants and vowels to shed new light on the evolution of human speech
Jan 09, 2015



Scientist still don’t know how human speech evolved from our great ape ancestors. But a study involving Liverpool John Moores University (LJMU) and the Pongo Foundation has uncovered new calls from orang-utans that show fundamental similarities with human spoken languages offering a potential origin point for speech evolution.

Appearing this week in the scientific journal PLOS ONE the research shows that orang-utans, and perhaps other great apes as well, can learn to produce new calls which display similarities with human consonants and vowels.

The study was led by Adriano Lameira from the Pongo Foundation. He explained the findings:

“These calls were produced by quickly opening-and-closing the lips, much alike humans do when talking. One of these calls presented similarities with human consonants, and the other with human vowels, the two basic building blocks of human speech.

“Speech underlines every social and community structure in human society, yet the origin of all the world’s spoken languages remains a puzzle ever since the publication of Darwin’s theory of natural selection. The major barrier for our understanding of the evolution of spoken language is the observation that great apes – our closest relatives – exhibit a very rigid use of their calls, and seem to lack the capacity to modify or learn new calls into their repertoire. This stands in stark contrast with human spoken languages, which are learned anew every generation, raising therefore critical questions about evolutionary continuity between our vocal repertoire and that of great apes. The new findings changes all of this as we can now see fundamental similarities.”

Not that word origins aren't interesting in and of themselves. but the distinctive feature of human language is grammar. Ape communication is totally devoid of that.

This question may be way too broad, too naive, etc., but what is generally seen as necessary for a grammar to exist?

Wild musings:
Could one take vowel and consonant ordering as a rudimentary grammar? If one could barely control one vowel and one consonant, how would words be formed except possibly from basic repetitive utterances that might have had some meaning associated with their internal ordering?

((Vowel, Consonant, Vowel)) might indicate one thing, whereas ((Consonant, Vowel, Consonant)) might indicate something else.
