Bacterial taxonomy Bacterial taxonomy Bacterial taxonomy is the taxonomy, i.e. the rank-based classification, of bacteria. 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
Carl Linnaeus difference is of nobility." Linnaeus added a second species to the genus "Homo" in "" based on a figure and description by Jacobus Bontius from a 1658 publication: "Homo troglodytes" ("caveman") and published a third in 1771: "Homo lar". Swedish historian Gunnar Broberg states that the new human species Linnaeus described were actually simians or native people clad in skins to frighten colonial settlers, whose appearance had been exaggerated in accounts to Linnaeus. In early editions of "", many well-known legendary creatures were included such as the phoenix, dragon, manticore, and satyrus, which Linnaeus collected into the catch-all category "Paradoxa".
