Document Summary
19. 1a linnaeus developed the system of binomial nomenclature. Linnaeus invented the system of binomial nomenclature. Carolus linnaeus was the first modern practitioner of taxonomy. Taxonomy: the science that identifies names, and classifies new species. Species are assigned a latinized two-part name. First part of the name identifies a genus. Second part of the name identifies the specific epithet. Morphological species concept: characterizes individuals that share anatomical characteristics with the same scientific name. Many binomials are descriptive of the organism or its habitat. 19. 1b linnaeus devised the taxonomic hierarchy to organize information about species. Classification: a conceptual filing system that arranges organisms into ever more inclusive. Taxonomic hierarchy: a nested series categories of formal categories: domain, kingdom, phylum, class, order, family, genus, species, subspecies. Organisms included within any category of the taxonomic hierarchy compose a taxon. Species that are included in the same taxon at the bottom of the hierarchy generally share many characteristics.
