Only in the Animal Kingdom is the higher taxonomy of Linnaeus still more or less recognizable and some of these names are still in use, but usually not quite for the same groups.

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.
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 ]
[10] [11] The taxa "animal kingdom" (or kingdom Animalia) and "plant kingdom" (or kingdom Plantae) remain in use by some modern evolutionary biologists. The initial targets of Cavalier-Smith's classification, the protozoa were classified as members of the animal kingdom, [12] and many algae were regarded as part of the plant kingdom. With ...
Carl Linnaeus [a] (23 May 1707 [note 1] – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné, [3] [b] was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms.
The Catalogue of Life's goal was to complete the global checklist of 1.9 million species by 2011. [7] As of May 2012, the Catalogue of Life has reached 1.4 million species—a major milestone in its quest to complete the first up-to-date comprehensive catalogue of all living organisms.
Bacteria were first observed by Antonie van Leeuwenhoek in 1676, using a single-lens microscope of his own design. [3] He did not distinguish bacteria as a separate type of microorganism, calling all microorganisms, including bacteria, protists, and microscopic animals, "animalcules".
Lycopodium (from Ancient Greek lykos, wolf and podion, diminutive of pous, foot) [2] is a genus of clubmosses, also known as ground pines or creeping cedars, [3] in the family Lycopodiaceae.
