Abstract

Historical language change (“glossogeny”), like evolution itself, is a fact; and its implications for the biological evolution of the human capacity for language acquisition (“phylogeny”) have been ably explored by many contemporary theorists. However, Christiansen & Chater's (C&C's) revolutionary call for a replacement of phylogenetic models with glossogenetic cultural models is based on an inadequate understanding of either. The solution to their “logical problem of language evolution” lies before their eyes, but they mistakenly reject it due to a supposed “circularity trap.” Gene/;culture co-evolution poses a series of difficult theoretical and empirical problems that will be resolved by subtle thinking, adequate models, and careful cross-disciplinary research, not by oversimplified manifestos.
