 This diversity may be thought to support conventionalism about natural kinds (Section 1.1.2). But supporters of naturalism about our classifications (Section 1.1.1) will deny that the dispute in systematics reflects an indeterminacy in the natural world. A monist will hold that one of the existing systems is a superior account of the natural world. A commitment to one of the different systems over another will result in a different ontological account of species. The most prevalent system of classification in contemporary systematics is cladistics, which classifies organisms phylogenetically, in virtue of shared derived features or an organism’s place in the genealogical tree.
