It has long been generally considered that human speech requires a low larynx, and that the high larynx of nonhuman primates should pre- clude their producing the vowel systems universally found in human language. Examining the vocalizations through acoustic analyses, tongue anatomy, and modeling of acoustic potential, we found that baboons (Papio papio) produce sounds sharing the F1/F2 formant structure of the human [ɨæɑ ɔ u] vowels, and that similarly with humans those vocalic quali- ties are organized as a system on two acoustic-anatomic axes. This confirms that hominoids can produce contrasting vowel qualities despite a high larynx. It suggests that spoken lan- guages evolved from ancient articulatory skills already present in our last common ancestor with Cercopithecoidea, about 25 MYA.", "link"=>"http://www.mendeley.com/research/evidence-vocalic-protosystem-baboon-papio-papio-suggests-prehominin-speech-precursors", "reader_count"=>62, "reader_count_by_academic_status"=>{"Researcher"=>15, "Student > Doctoral Student"=>2, "Student > Ph.
