Variation in language use is different from variation in genes
Some comments on Haider’s model of grammar change
This commentary discusses some aspects of Haider’s model of grammar change that are problematic from the
perspective of usage-based approaches to language change. These aspects include (i) the postulated equivalence between
intentionality and teleology, (ii) the metaphorical nature of Darwinism when applied to other domains, and (iii) the nature of
explanations of language change. With respect to (i), it is argued that equating intentionality with teleology disregards the fact
that innovation in grammar is not unprincipled like in genes. With respect to (ii), the question is whether a comparison between
as different concepts as human behaviors/brains and genes/populations can be considered as more than a metaphor (however
powerful). Finally, with respect to (iii), a number of diachronic-typological studies are discussed that concur to suggest that
variation in speakers’ verbal productions is largely adaptive, and therefore selection operates on a skewed pool of variants in
which non-adaptive/dysfunctional variants are a minority (if any).
