The term sister group is used in phylogenetic analysis, however, only groups identified in the analysis are labeled as "sister groups".. An example is birds, whose commonly cited living sister group is the crocodiles, but that is true only when discussing extant organisms; [3] [4] when other, extinct groups are considered, the relationship between birds and crocodiles appears distant.
This page provides information about "taxonomy templates" – templates whose names are of the form Template:Taxonomy/taxon. These act as a "database", storing information about taxa and their taxonomic relationships. There's usually someone to help at Wikipedia talk:Automated taxobox system if you have any questions.
The component programs of phylip use several different formats, all of which are relatively simple. Programs for the analysis of DNA sequence alignments, protein sequence alignments, or discrete characters (e.g., morphological data) can accept those data in sequential or interleaved format, as shown below.
The taxonomy templates are pages with titles of the general form "Template:Taxonomy/taxon" where taxon represents the name of the taxon. To show that a plant genus with the nonsense name Junkia is in the family Junkiaceae, you would create a page with the title "Template:Taxonomy/Junkia". When finished, the page would look something like this:
The International Code of Phylogenetic Nomenclature, known as the PhyloCode for short, is a formal set of rules governing phylogenetic nomenclature. Its current version is specifically designed to regulate the naming of clades , leaving the governance of species names up to the rank-based nomenclature codes ( ICN , ICNCP , ICNP , ICZN , ICVCN ).
Purely in the context of modern taxa, Lepidosauria can be considered the sister taxon to Archelosauria, which includes Testudines (turtles), Aves (birds) and Crocodilia (crocodilians). Lepidosauria is encompassed by Lepidosauromorpha, a broader group defined as all reptiles (living or extinct) closer to lepidosaurs than to archosaurs.
Phylogenetic nomenclature is a method of nomenclature for taxa in biology that uses phylogenetic definitions for taxon names as explained below. This contrasts with the traditional method, by which taxon names are defined by a type, which can be a specimen or a taxon of lower rank, and a description in words. [1]
A taxon identifier works in much the same way that a barcode is used to retrieve data about an item of interest. When used on Wikipedia, taxon identifiers can be found near the bottom of Wikipedia pages, linking to records on taxonomic databases. In many cases, each taxon name in a taxonomic database has a unique identifier, although this is ...
