Adaptation to moving targets: Culture/gene coevolution, not either/or

Abstract

We agree that much of language evolution is likely to be adaptation of languages to properties of the brain. However, the attempt to rule out the existence of language-specific adaptations a priori is misguided. In particular, the claim that adaptation to "moving targets" cannot occur is false. Instead, the details of gene-culture coevolution in language are an empirical matter. © 2008 Cambridge University Press.
