==Hierarchy of ranks==
For some clades, a number of additional classifications are used. The different classes are used relatively rarely.

== History of the concept ==
The class as a distinct rank of biological classification having its own distinctive name (and not just called a ''top-level genus'' ''(genus summum)'' was first introduced by a [[France|French]] [[botanist]] [[Joseph Pitton de Tournefort]] in his classification of plants (appeared in his 1694 ''Eléments de botanique''). [[Carl Linnaeus|Carolus Linnaeus]] was the first to use it consistently, in dividing of all three of his [[Kingdom (biology)|kingdoms]] of Nature ([[mineral]]s, [[plant]]s, and [[animal]]s) in his ''[[Systema Naturae]]'' (1735, 1st ed.).<ref>[[Ernst Mayr|Mayr E.]] (1982). ''The Growth of Biological Thought''. Cambridge: The Belknap Press of Harvard University Press. ISBN 0-674-36446-5</ref> Since then class had been considered the highest level of the taxonomic hierarchy until the ''embranchements'', now called [[Phylum|phyla]], and [[Division (biology)|divisions]] were introduced in the nineteenth century.
