Various biological taxonomies

.Biological classification (sometimes known as "Linnaean taxonomy") is still generally the best known form of taxonomy.^ This form of "bookkeeping", known as taxonomy, was started by Swedish physician and naturalist, Carolus Linnaeus (1707-1778), in his work Systema Naturae , in 1735.

 The best-known form of this is cladistics.
The results of cladistic analyses are often represented as cladograms. .It is held by cladists that taxa (if recognized) must always correspond to clades, united by apomorphies (derived traits) which are discovered by a cladistic analysis.^ A biological taxonomy is cladistic if all the taxa are clades.

In numerical taxonomy, numerical phenetics or taximetrics, the taxonomy is exclusively based on cluster analysis and neighbor joining to best-fit numerical equations that characterize measurable traits of a number of organisms. .It results in a measure of evolutionary "distance" between species.^ Disruptive selection results in evolutionary changes and new species; once this occurs, however, the subpopulations enter into stabilizing selection evolution v.

Military taxonomy

Military theorist Carl von Clausewitz stressed the significance of grasping the fundamentals of any situation in the "blink of an eye" (coup d'œil). In a military context, the astute tactician can immediately grasp a range of implications and can begin to anticipate plausible and appropriate courses of action.[8] Clausewitz' conceptual "blink" represents a tentative ontology which organizes a set of concepts within a domain.
The term "military taxonomy" encompasses the domains of weapons, equipment, organizations, strategies, and tactics.[9] .The use of taxonomies in the military extends beyond its value as an indexing tool or record-keeping template[10] -- for example, the taxonomy-model analysis suggests a useful depiction of the spectrum of the use of military force in a political context.^ Evaluating taxonomy tools provided by various vendors in the world right now.  What do these tools actually do?  Are they useful?  What is the scope of their taxonomy service and application?

Simple English

Taxonomy is a science. It is about the classification of all things living. Although it is most commonly used in biology, it can be used in other types of classification too. Taxonomy is used with different ranks, the lowest is a species. There can also be sub-species. An organism is a species if two organisms of the same kind can mate. This name is the scientific classification of that species. The name is the same all over the world, so that when scientists from different places talk or write about the living thing, they can understand each other.

The highest rank in the domain of living things is the Kingdom. Each kingdom has many smaller groups in it, called Phyla: see List of animal phyla. Each Phylum has more smaller groups in it, called Classes. This pattern looks like branches on a tree with smaller branches growing from them. Each species is put into a group because of what it does, how and what it eats, special body parts, and so on. At the end of the pattern, the groups (Genera) are very small. Then each species in the Genus is given its own name. When someone writes about a living thing and uses this name, they only write the Genus name and the species name, like this:

Felis silvestris catus (domestic cat)

When someone writes about this animal, the first time they write its name they will write Felis silvestris catus. After the first time they write its name, they will only write the first letter of the Genus, so they will write F. silvestris catus. This is known as binomial nomenclature, because it is a way to describe organisms using two names, the first is the Genus name, and the second is the adjective that denotes the specific species of that genus.

These are the major groups (ranks) used in taxonomy:

Kingdom --> Phylum --> Class --> Order --> Family --> Genus --> Species

A mnemonic, or a saying to help a person remember something, for that is "King Phillip Came Over From Greater Spain","King Phillip Came Over For Good Spaghetti", and King Phillip Cried Out "For Goodness Sake".
