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

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.

Such an order has been recognized by a few systems of plant taxonomy, with a various placement.

Some official bodies have adopted the proposed Sibley-Ahlquist taxonomy almost entirely, however a more common approach worldwide has been to retain the traditional groupings, and modify rather than replace them in the light of new evidence as it comes to hand.

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.

For example, the skills, rules, and knowledge taxonomy of human behavior has been used by designers to develop systems that are compatible with multiple " ways of knowing ": abstract analytic reasoning, experience-based ' gut feelings ', and ' craft ' sensorimotor skills.

Despite the numerous oppositions, Haeckel has influenced many disciplines in science in his drive to integrate such disciplines of taxonomy and embryology into the Darwinian framework and to investigate phylogenetic reconstruction through his Biogenetic Law.

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 jackals has evolved with scientific understanding about how they are related on the canid family tree.

His taxonomy of minerals has dropped long since from use.

Cosmologist Max Tegmark has provided a taxonomy of universes beyond the familiar observable universe.

The taxonomy of the red wolf has been debated since before efforts began in 1973 to save it from extinction.

Many agency reports, books and web pages list the red wolf as Canis rufus but recent genetic research has opened a new debate about the taxonomy of both the red wolf and Canada's eastern wolf ( Canis lycaon ).

The taxonomy has undergone changes and is likely to change further, as a number of genetic studies are bringing forth new information.

This method has become quite rare in modern times, having been largely superseded by cladistic analyses, as numerical taxonomy is sensitive to being misled by plesiomorphic traits.

Rather than propose a single definition for ubiquitous computing and for these related terms, a taxonomy of properties for ubiquitous computing has been proposed, from which different kinds or flavors of ubiquitous systems and applications can be described.

In literature, genre has been known as an intangible taxonomy.

The Sibley-Ahlquist taxonomy, which has been widely accepted in America, lumps all the Charadriiformes together with other seabirds and birds of prey into a greatly enlarged order Ciconiiformes.

DNA evidence has confirmed common ancestry for all Procellariiformes, however, the taxonomy within the order is complex and fluctuating.

The taxonomy of this group of plants within the Rosaceae has recently been unclear.

The taxonomy of this subfamily has changed several times in the last century as more detailed studies have been carried out.
