I do have the strong impression that the fixity of species predates Linnaeus
by millenia. Aristotle and Plato both maintained it, and if not always
unquestioned it was the standard assumption up to around the mid-18th
century. Linnaeus himself questioned it, incidentally, in a few instances
of apparent hybridization in plants.
