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.
Taxonbar displays these links as short strings, indicating the unique identifier each database has assigned the taxon for catalogue purposes. Taxonomic identifiers of each taxon are stored and retrieved from each taxon's corresponding Wikidata entry, but can be overridden in individual articles with locally entered data. Adding the data to ...
(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.
The name of an extinct taxon can be preceded by one of the following markers: † † {{extinct}}. Any of them will appear as † in the output. Any of them will appear as † in the output. The † will not be italicized and will not be included in a wikilink.
Each program is controlled through a menu, which asks users which options they want to set, and allows them to start the computation. The data is read into the program from a text file, which the user can prepare using any word processor or text editor (but this text file cannot be in the special format of the word processor, it must instead 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.)
Gnathifera is a member of Spiralia. It is the sister taxon of a clade comprising all other spiralians. [1] [20] An alternative phylogeny place Gnathifera into a main spiralian clade Platyzoa s.l. as sister clade to Mesozoa and Platyhelminthes. [22]
Taxonomic databases digitize scientific biodiversity data and provide access to taxonomic data for research. [1] Taxonomic databases vary in breadth of the groups of taxa and geographical space they seek to include, for example: beetles in a defined region, mammals globally, or all described taxa in the tree of life.
