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.
Some sequence analysis programs such as the ClustalW alignment program can write data files in the PHYLIP format. Most of the programs look for the data in a file called infile. If the phylip programs do not find this file, they then ask the user to type in the file name of the data file. [2]
|taxon= now specifies the lowest ranked taxon that will be handled automatically via a taxonomy template; if this taxon is not a genus, |genus_text= supplies the full wikitext of the genus name, complete with all required formatting including bold text if it is the lowest ranked name in the taxobox. If not the lowest rank, a link should be ...
This says that taxon-name/skip has the same values of rank, extinction status, etc. as taxon-name, except that its parent is parent-taxon-name, which will be higher up the taxonomic hierarchy. (When creating a skip taxonomy template, it can be prefilled if you use the correct page naming convention.)
Automatic taxonomy construction (ATC) is the use of software programs to generate taxonomical classifications from a body of texts called a corpus. ATC is a branch of natural language processing , which in turn is a branch of artificial intelligence .
(For example, the International Plant Names Index regularly has multiple identifiers for a taxon name, often but not always of the form N-1, N-2, etc.) Taxon identifiers enable researchers to search more easily for pertinent information on the subject of an article, without needing to disambiguate the subject manually.
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]
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 ).
