Systematics and Taxonomy Definitions

Winston (1999, p. 9) describes taxonomy as a “subdivision of systematics (the study of biological diversity] consisting of […] identi cation (referring a specimen to a previously classi ed and named group), classi fication (ordering organisms into groups based on perceived similarities or diff erences), and  nomenclature (naming groups of organisms according to rules developed for the process).”
