The language faculty, no doubt, is the very faculty that characterizes the human species. The evolution of this faculty has been described as a coevolutionary process of neurological adaptations and changes in language use (Deacon, 1992). We do not know what these changes in language use during the early phylogenesis of the language faculty may have been. What appears, however, to be a central characteristic of language use is the fact that spoken language is produced and perceived as a sequence in time.
