This complicates taxonomy and Amaranthus has generally been considered among systematists as a " difficult " genus.

The taxonomy of the genus has been controversial.

Paleontological classifications have yet to incorporate this new taxonomy, and continue to use Hydrochoeridae for all capybaras, while using Hydrochoerinae for the living genus and its closest fossil relatives, such as Neochoerus.

It seems likely that they will be placed into a new genus or family in the next revision of the taxonomy of this group.

* Alopex: Arctic fox, although the definitive mammal taxonomy list as well as genetic evidence places it in Vulpes, and not as a genus unto itself.

Similarities between jackals and coyotes led Lorenz Oken, in 1816, in the third volume of his Lehrbuch der Naturgeschichte, to place these species into a new separate genus, Thos, after the classical Greek word " jackal ", but his theory had little immediate impact on taxonomy at the time.

Heller's names and the designations he gave to various jackal species and subspecies live on in current taxonomy, although the genus has been changed from Thos to Canis.

The IUCN reported in 2008, " The taxonomy of this genus is clearly in need of review, and it is likely that O. orca will be split into a number of different species or at least subspecies over the next few years.

In the taxonomy of Linnaeus there are three kingdoms, divided into classes, and they, in turn, into orders, families, genera ( singular: genus ), and species ( singular: species ), with an additional rank lower than species.

In creation science, creationists accepted speciation as occurring within a " created kind " or " baramin ", but objected to what they called " third level-macroevolution " of a new genus or higher rank in taxonomy.

The taxonomy of the genus Mimosa has had a tortuous history, having gone through periods of splitting and lumping, ultimately accumulating over 3, 000 names, many of which have either been synonymized under other species or transferred to other genera.

The alpha, beta, delta, epsilon sections are monophyletic, bar the Gammaproteobacteria due to the Acidithiobacillus genus is paraphyletic to Betaproteobacteria, according to multigenome alignment studies, which if done correctly are more precise than 16S ( note that Mariprofundus ferrooxydans sole member of the Zetaproteobacteria was previously misclassified on NCBI taxonomy ).

The taxonomy of the genus Brettanomyces has been debated since its early discovery and has seen many re-classifications over the years.

Shortly after, the formation of ascospores was observed and the genus Dekkera, which reproduces sexually ( teleomorph form ), was introduced as part of the taxonomy.

His research foci have included the evolution and fate of the European Neandertals, the role of culture in early hominid evolution, the nature and explanation of allometry, robust australopithecine evolution, the distribution and explanation of sexual dimorphism, hominid origins, the pattern and explanation of Australasian hominid evolution, the contributions and role of genetics in paleoanthropological research, and the taxonomy of the genus Homo.

None of the nomenclature codes require such criteria for defining a genus, because these are concerned with the nomenclature rules, not with taxonomy.

In either case, a name change of the genus would have implications on the taxonomy of extinct species closely related to humans, including Australopithecus.

In phylogenetic taxonomy, the genus has been used as a reference point in the definition of Dinosauria ; Dinosaurs have been designated as all descendants of the most recent common ancestor of Triceratops and Neornithes ( i. e. modern birds ).

Kudzu (; Pueraria lobata, and possibly other species in the genus Pueraria ; see taxonomy section below ) is a plant in the genus Pueraria in the pea family Fabaceae, subfamily Faboideae.

The latest comprehensive review of Australian bird taxonomy by Christidis and Boles also places this genus in the Timaliidae.

* Overview of taxonomy of Strongyloides genus.

The taxonomy of the genus of the pygmy hippopotamus has changed as understanding of the animal has developed.

Categories form part of a hierarchical structure when applied to such subjects as taxonomy in biological classification: higher level: life-form level, middle level: generic or genus level, and lower level: the species level.

The name and order Asterales is botanically venerable, dating back to at least 1926 in the Hutchinson system of plant taxonomy when it contained only five families, of which only two are retained in the APG III classification.

The taxonomy is further differentiated by sections within each of the subgenera.

Biological classification is a form of scientific taxonomy.

Modern taxonomy is rooted in the work of Carolus Linnaeus, who grouped species according to shared physical characteristics.

The dominant classification system is called the Linnaean taxonomy.

The classification, taxonomy, and nomenclature of botanical organisms is administered by the International Code of Nomenclature for algae, fungi, and plants ( ICN ).

In Flynn's taxonomy, this strategy is known as Multiple Instructions-Multiple Data or MIMD.

He is known as the father of modern taxonomy, and is also considered one of the fathers of modern ecology.

Compared to other plant families, the taxonomy of the family is poorly understood due to their great diversity, difficulty in identifying and reduced taxonomic work done on it.

The inclusion of additional polysaccharides in algal cells walls is used as a feature for algal taxonomy.

Bird taxonomy has been in a state of flux for some years, and it is reasonable to expect that the large differences between different classification schemes will continue to gradually resolve themselves as more evidence becomes available.

The difference is one of weight: While phylogenetic nomenclature bases the group on an ancestor with a certain trait, Linnaean taxonomy uses the traits themselves to define the group.

Biological taxonomy is not fixed, and placement of taxa is reviewed as a result of new research.

The taxonomy of fossil hydrochoerines is also in a state of flux.

This article is about bird taxonomy ; for the topic in pottery and glassware design, see Carinate.

There is a larger taxonomy of movement, such as commuting, foraging, territorial behaviour, stasis, and ranging.

The taxonomy is considered to have a greater influence internationally than in the United States.

Internationally, the taxonomy is used in every aspect of education from training of the teachers to the development of testing material.

Neither term is part of a rigorous taxonomy — instead they are approximate ways of characterizing stories that reviewers and commentators have found useful.

In referring to taxonomy of the Animalia, " invertebrata " is a term of convenience, not a taxon ; it has very little circumscriptional significance except arguably within the Chordata.

The taxonomy of the three families is complex and rather controversial.
