Chimpanzee Lip-Smacks help Trace Evolution of Language
Chimpanzees produce lip-smacks at a speech-like rhythm of open-close mouth cycles, suggesting that speech-rhythm was built upon existing primate signal systems
In the paper ‘Chimpanzee lip-smacks confirm primate continuity for speech-rhythm evolution’, published in Biology Letters, a consortium of UK-based researchers have found that the rhythm of chimpanzee...
