  2. Order (biology) - Wikipedia

    en.wikipedia.org/wiki/Order_(biology)

    Order (Latin: ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class . In biological classification , the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes .

  3. Taxonomic rank - Wikipedia

    en.wikipedia.org/wiki/Taxonomic_rank

    An example is Lithobates (Aquarana) catesbeianus, which designates a species that belongs to the genus Lithobates and the subgenus Aquarana. [15] A subspecies has a name composed of three parts (a trinomial name or trinomen): generic name + specific name + subspecific name; for example Canis lupus italicus. As there is only one possible rank ...

  4. Taxonomy (biology) - Wikipedia

    en.wikipedia.org/wiki/Taxonomy_(biology)

    Taxonomy is that part of Systematics concerned with topics (a) to (d) above. A whole set of terms including taxonomy, systematic biology, systematics, scientific classification, biological classification, and phylogenetics have at times had overlapping meanings – sometimes the same, sometimes slightly different, but always related and ...

  5. Tree of life (biology) - Wikipedia

    en.wikipedia.org/wiki/Tree_of_life_(biology)

    Edward Hitchcock's fold-out paleontological chart in his 1840 Elementary Geology. Although tree-like diagrams have long been used to organise knowledge, and although branching diagrams known as claves ("keys") were omnipresent in eighteenth-century natural history, it appears that the earliest tree diagram of natural order was the 1801 "Arbre botanique" (Botanical Tree) of the French ...

  6. Taxonomy - Wikipedia

    en.wikipedia.org/wiki/Taxonomy

    For example, a basic biology taxonomy would have concepts such as mammal, which is a subset of animal, and dogs and cats, which are subsets of mammal. This kind of taxonomy is called an is-a model because the specific objects are considered as instances of a concept. For example, Fido is-an instance of the concept dog and Fluffy is-a cat. [23]

  7. Clade - Wikipedia

    en.wikipedia.org/wiki/Clade

    In the diagram, lemurs and lorises are sister clades, while humans and tarsiers are not. A clade A is basal to a clade B if A branches off the lineage leading to B before the first branch leading only to members of B. In the adjacent diagram, the strepsirrhine/prosimian clade, is basal to the hominoids/ape clade. In this example, both ...

  8. Phylogenetic tree - Wikipedia

    en.wikipedia.org/wiki/Phylogenetic_tree

    A spindle diagram is not an evolutionary tree: [18] the taxonomic spindles obscure the actual relationships of the parent taxon to the daughter taxon [17] and have the disadvantage of involving the paraphyly of the parental group. [19] This type of diagram is no longer used in the form originally proposed. [19]

  9. Taxonomic sequence - Wikipedia

    en.wikipedia.org/wiki/Taxonomic_sequence

    Taxonomic sequence (also known as systematic, phyletic or taxonomic order) is a sequence followed in listing of taxa which aids ease of use and roughly reflects the evolutionary relationships among the taxa. Taxonomic sequences can exist for taxa within any rank, that is, a list of families, genera, species can each have a sequence.
