Knowra Taxonomic rank Taxonomic rank A level in the hierarchy used to classify organisms, such as species, genus, family, or order. Each rank groups taxa at a particular position in that hierarchy.
Taxon : A named group of organisms treated as a unit in biological classification. Ranks assign each taxon a position in the classification hierarchy.
Linnaean taxonomy : A classification tradition that organizes organisms into ranked groups, including kingdom, class, order, family, genus, and species. Its familiar sequence supplies the standard ranks used in many classifications.
Phylogenetic nomenclature : A system for naming groups based on ancestry and evolutionary relationships, often without assigning Linnaean ranks. It names evolutionary groups without relying on the same ranked hierarchy.
Scientific name : A formal name assigned to an organism or taxon under a nomenclatural code. Scientific names often reveal a taxon's rank through their structure and endings.
Taxonomy : The science and practice of naming, defining, and classifying organisms. Taxonomic ranks form the hierarchical framework used in classification.
International Code of Zoological Nomenclature : The rules governing scientific names for animals and the taxa to which those names apply. It regulates zoological names at ranks such as family, genus, and species.
Cladistics : A method of classifying organisms by shared derived characteristics and branching evolutionary relationships. Its emphasis on clades can conflict with classifications that prioritize familiar ranks.
Binomial nomenclature : The two-part system of naming species with a genus name followed by a specific epithet. It names organisms at the species level using the genus rank as its first part.
Biological nomenclature : The system of rules for assigning scientific names to organisms and groups. Rank influences the form and ending of many taxon names.
International Code of Nomenclature for algae, fungi, and plants : The rules governing scientific names for algae, fungi, and plants, including naming conventions at different ranks. It sets naming rules that vary with a taxon's rank.
