On the Evolution of Human Language.
Human linguistic ability depends, in part, on the gradual evolution of man's supralaryngeal vocal tract. The anatomic basis of human speech production is the result of a long evolutionary process in which the Darwinian process of natural selection acted to retain mutations. For auditory perception, the listener operates in terms of the acoustic pattern of the entire syllable according to the "motor theory of speech perception." According to the theory, human listeners perceive speech in terms of the constraints imposed by the speech-producing apparatus. It has recently been possible to reconstruct the supralaryngeal vocal tracts of extinct hominid species. Computer-implemented supralaryngeal vocal tract modelling indicates that these extinct species lacked the anatomic ability necessary to produce the range of sounds necessary for human speech.
