Linguistic Selection: An Utterance-based Evolutionary Theory of Language Change

Abstract

Hull (1988) uses recent developments in the theory of biological evolution, in particular rigorous application of the population theory of species, a consistently phylogenetic approach to evolutionary taxonomy and a proposed resolution of the dispute over which levels natural selection operates, to propose a general analysis of selection processes which he then applies to conceptual change in science. Hull's model of selection is applied to language change. It is argued that the utterance plays the central role in linguistic selection, and causal mechanisms by which linguistic selection – language change – occurs are proposed. The final sections consider the possibility that selection occurs also at higher levels of linguistic organization, and suggest how language contact may be accounted for in terms of phylogenetic reticulation.
