acquisition process, the deep integration of language and human cognition, and the involvement and synergistic interaction of widespread and diverse brain systems in language processes together imply that there has been long-term adaptation involving a very broad suite of genetic loci and the involvement of many levels of intraevolutionary mechanisms. We are more likely to succeed at solving this mystery if we approach it with the expectation that nature produces her most complex works by a logic that is vastly more subtle, and entirely unlike the methods of a watchmaker or computer scientist.
