  2. Kingdom (biology) - Wikipedia

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

    Combined with the five-kingdom model, this created a six-kingdom model, where the kingdom Monera is replaced by the kingdoms Bacteria and Archaea. [16] This six-kingdom model is commonly used in recent US high school biology textbooks, but has received criticism for compromising the current scientific consensus. [ 13 ]

  3. Three-domain system - Wikipedia

    en.wikipedia.org/wiki/Three-domain_system

    The three-domain system adds a level of classification (the domains) "above" the kingdoms present in the previously used five- or six-kingdom systems.This classification system recognizes the fundamental divide between the two prokaryotic groups, insofar as Archaea appear to be more closely related to eukaryotes than they are to other prokaryotes – bacteria-like organisms with no cell nucleus.

  7. Taxonomic rank - Wikipedia

    en.wikipedia.org/wiki/Taxonomic_rank

    There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, and species. In addition, domain (proposed by Carl Woese) is now widely used as a fundamental rank, although it is not mentioned in any of the nomenclature codes, and is a synonym for dominion (Latin: dominium), introduced by Moore in 1974. [12] [13]

    en.wikipedia.org/wiki/Carl_Woese

    Carl Richard Woese (/ w oʊ z / WOHZ; [3] July 15, 1928 – December 30, 2012) was an American microbiologist and biophysicist. Woese is famous for defining the Archaea (a new domain of life) in 1977 through a pioneering phylogenetic taxonomy of 16S ribosomal RNA , a technique that has revolutionized microbiology.

  9. Taxonomy (biology) - Wikipedia

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

    First proposed in 1977, Carl Woese's three-domain system was not generally accepted until later. [69] One main characteristic of the three-domain method is the separation of Archaea and Bacteria , previously grouped into the single kingdom Bacteria (a kingdom also sometimes called Monera ), [ 68 ] with the Eukaryota for all organisms whose ...
