Abstract

A number of language evolution researchers have argued that while language as we now know it is a predominately vocal affair, early language plausibly made extensive use of gesture. Relatedly, these same researchers often claim that while modern language in general uses arbitrary symbols, it is very likely that early language made extensive use of iconicity. Anyone accepting an account of early language along these lines must therefore explain how language shifted over time from a heavily gestural and iconic communication system to a predominately vocal and highly arbitrary one. This article looks at an intriguing theory advanced by Woll as to how this shift was made. We find the spirit of the theory plausible but take issue with its details. Specifically, we identify a serious tension at the core of the theory. We then go on to explore how that tension might be plausibly resolved. The result is a blueprint for a much-improved version of the theory, in our view.
