Objections to the use of vernacular terms like "bird" and "dinosaur" seem to
arise from a concern that these folk taxa are somehow essentialistically
defined (see De Queiroz 1992, Gauthier and de Queiroz 2001, Gelman 2008, Gelman
and Hirschfeld 1999). But dinosaur itself arose out of science (Owen), as did
mammal (Linnaeus), and it seems to me that the technical nomenclature is a way
in which vernacular terms are redfined by what philosophers call "the division
of linguistic labor" - experts can change ordinary language. Not alone, of
course, and not by fiat, but using such events as a way to influence popular
thought, and educational ideas.
