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
Structure (category theory) operations will be needed. "Presentation of a category" (analogously to presentation of a group) can in fact be approached in a number of ways, the "category" structure not being (quite) an algebraic structure in its own right. The term "transport of structure" is the 'French' way of expressing "covariance" or "equivariance" as a constraint: transfer structure by a surjection and then (if there is an existing structure) compare. Since any group is a one-object category, a special case of the question about "what the morphisms preserve" is this: how to consider any group G as a symmetry group? That is
