  All of these processes have likely played a role in the evolution of our capacities to learn and use a natural language.  Pre-existing psychological, perceptual and motor capacities would have been recruited for the task of language learning and use. These capacities would have been honed and specialized further by natural selection for the performance of linguistic tasks. The functions of some of them, perhaps, would have become so specialized for language-related tasks that they cease to perform any non-linguistic functions at all — and to this extent, perhaps, linguistic nativism would be vindicated. At the same time, however, language itself would have been evolving so as the better to suit our cognitive and perceptual capacities, and our communicative needs.  Given the fact that many different perceptual, motor and cognitive systems are implicated in language use and learning, and given the co-evolution of our minds and our languages, the truth about language evolution, when it emerges, is unlikely to be a simple. For this reason, it is unlikely to vindicate the nativist's notion that a specialized and monolithic ‘language organ’ or ‘faculty’ is at the root of our linguistic capacities.
