Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification).
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. [2]
Taxonomy is that part of Systematics concerned with topics (a) to (d) above. A whole set of terms including taxonomy, systematic biology, systematics, scientific classification, biological classification, and phylogenetics have at times had overlapping meanings – sometimes the same, sometimes slightly different, but always related and ...
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank [1] because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a taxon) in a hierarchy that reflects evolutionary
Biological taxonomy is not fixed, and opinions about the correct status of taxa at all levels, and their correct placement, are constantly revised as a result of new research. Many aspects of classification remain a matter of scientific judgment. The ITIS database is updated to take account of new research as it becomes available. [citation needed]
The project uses a supertree approach to generate a single phylogenetic tree (served at tree.opentreeoflife.org [5]) from a comprehensive taxonomy and a curated set of published phylogenetic estimates. The taxonomy is a combination of several large classifications produced by other projects; it is created using a software tool called "smasher". [6]
The web interface displays a tree based on the taxonomy (not the entire Newick file), down to the genome assembly level. Each genome assembly has a page detailing its metadata and a history of how it's classified in each GTDB release. There is a search functionality.
