<P> In the scientific classification established by Carl Linnaeus , each species has to be assigned to a genus ( binary nomenclature ) , which in turn is a lower level of a hierarchy of ranks ( family , suborder , order , subclass , class , division / phyla , kingdom and domain ) . In the currently accepted classification of life , there are three domains ( Eukaryotes , Bacteria and Archaea ) , which , in terms of taxonomy , despite following the same principles have several different conventions between them and between their subdivisions as are studied by different disciplines ( botany , zoology , mycology and microbiology ) , for example in zoology there are type specimens , whereas in microbiology there are type strains . </P>
