Class (biology) - Citizendia

The hierarchy of biological classification's major eight taxonomic ranks. Taxonomic rank ( rank, category, taxonomic category is an abstract term used in the Scientific classification, or Taxonomy, of organisms Intermediate minor rankings are not shown.

A class is the taxonomic rank in the biological classification of organisms in biology below phylum and above order. Taxonomic rank ( rank, category, taxonomic category is an abstract term used in the Scientific classification, or Taxonomy, of organisms Foundations of modern biology There are five unifying principles A phylum ( Plural: phyla) is a Taxonomic rank between Kingdom and above Class. This article is about the taxonomic rank for the sequence of species in a taxonomic list see Taxonomic order In scientific classification used

For example, Mammalia is the class used in the classification of dogs, whose phylum is Chordata (animals with notochords) and order is Carnivora (mammals that eat meat). Mammals ( class Mammalia) are a class of Vertebrate Animals characterized by the presence of Sweat glands, including sweat glands The dog ( Canis lupus familiaris) is a domesticated Subspecies of the gray wolf, a Mammal of the Canidae family of the order Chordates ( Phylum Chordata) are a group of Animals that includes the Vertebrates together with several closely related Invertebrates The notochord is a flexible rod-shaped body found in Embryos of all Chordates It is composed of cells derived from the Mesoderm and defines the The diverse order Carnivora (kɑrˈnɪvərə or sometimes /ˌkɑrnɪˈvɔərə/ from Latin carō (stem carn-) "flesh" + vorāre

History of the concept

The class as a distinct of biological classification having its own distinctive name (and not just called a higher genus (genus summum)) was first introduced by a French botanist Joseph Pitton de Tournefort in his classification of plants (appeared in his 1694 Eléments de botanique).

Since then class had been considered the highest level of the taxonomic hierarchy until the embranchements, now called phyla, and divisions were introduced in the nineteenth century. A phylum ( Plural: phyla) is a Taxonomic rank between Kingdom and above Class.
