The hierarchy of biological classification's eight major taxonomic ranks.A family contains one or more genera. Intermediate minor rankings are not shown. Genus (/ ˈ dʒ iː n ə s /; pl.: genera / ˈ dʒ ɛ n ər ə /) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses.

In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages.
The science of classification, in biology the arrangement of organisms into a classification [4] "The science of classification as applied to living organisms, including the study of means of formation of species, etc." [5] "The analysis of an organism's characteristics for the purpose of classification" [6]
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank [1] because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a taxon) in a hierarchy that reflects evolutionary relationships.

Human taxonomy is the classification of the human species within zoological taxonomy. The systematic genus , Homo , is designed to include both anatomically modern humans and extinct varieties of archaic humans .
One taxon of each category must include the type genus. The names of the taxa which include the type genus must be formed by the addition of the appropriate suffix to the stem of the name of the type genus[…]." [3] In 2019, it was proposed that all ranks above genus should use the genus category as the nomenclatural type. [4]
Bacterial taxonomy is subfield of taxonomy devoted to the classification of bacteria specimens into taxonomic ranks. Archaeal taxonomy are governed by the same rules. In the scientific classification established by Carl Linnaeus , [ 1 ] each species is assigned to a genus resulting in a two-part name.
