The type species, A. sarcophagus, was apparently restricted in range to the modern-day Canadian province of Alberta, after which the genus is named.

In Central and South America, the alligator family is represented by five species of the genus Caiman, which differs from the alligator by the absence of a bony septum between the nostrils, and the ventral armour is composed of overlapping bony scutes, each of which is formed of two parts united by a suture.

The genus is divided into three subgenera:

The African elephant genus contains two living species ; whereas the Asian elephant species is the only surviving member of the Asian elephant genus, but can be divided into four subspecies.

Anthropologists in the 1980s were divided regarding some details of reproductive barriers and migratory dispersals of the Homo genus.

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.

Phyla ( or divisions ) are divided into classes, and they, in turn, into orders, families, genera ( singular: genus ), and species ( singular: species ).

* Is existence a genus or general class that is simply divided up by specific differences?

The genus is divided into two subgenera and a number of sections:

With the number of species increasing, the genus was divided into the two subgenera Magnolia and Yulania.

The clouded leopard ( Neofelis nebulosa ), which was divided in 2007 to distinguish the Bornean clouded leopard ( Neofelis diardi ), is generally placed at the basis of the Panthera group but is not included in the genus Panthera itself.

:* Species: This genus is divided into five species which are grouped to form the basis of reporting cirrus in the SYNOP code.

David Hunt divided the genus into 11 sections, with the nominate section broken down into a further four series.

The lovebird genus comprises nine species of which five are monotypic and four are divided into subspecies.

The genus contains many other spring-flowering plants, of which A. hortensis and A. fulgens have less divided leaves and splendid rosy-purple or scarlet flowers.

The genus is easily identified by its large, circular, palmately lobed leaves, about 30 – 40 cm in diameter and deeply divided into 7-11 lobes.

Christopher Grey-Wilson divided the genus into 9 subgenera ( Clematis, Cheiropsis, Flammula, Archiclematis, Campanella, Atragene, Tubulosae, Pseudanemone, Viorna ), several with sections and subsections within them.

The many species mentioned above are divided into two subgroups within the genus.

The genus Populus has traditionally been divided into six sections on the basis of leaf and flower characters ; this classification is followed below.

The genus can be divided into several growth forms:

The leaf morphology of the species within the genus is extremely varied, ranging from the sessile ovate leaves of D. erythrorhiza to the bipinnately divided acicular leaves of D. binata.

The latter ( colorless, shape-changing uniflagellates ) were divided among the Astasiaceae and the Peranemaceae, while flexible green Euglenoids were generally assigned to the genus Euglena.

( 2001 ) who demonstrated the genus Criniger must be divided into an African and an Asian ( Alophoixus ) lineage.

The genus Juglans is divided into four sections.

The fossil species assigned to the genus Machairodus were divided by Turner into two grades of evolutionary development-M. aphanistus and the North American " Nimravides " catacopis representing the more primitive grade, and M. coloradensis and M. giganteus representing the more derived grade.

The APG III system ( 2009 ) differs only in that the Limnocharitaceae are combined with the Alismataceae ; it was also suggested that the genus Maundia ( of the Juncaginaceae ) could be separated into a monogeneric family, Maundiaceae, but the authors noted that more study was necessary before Maundiaceae could be recognized.

Some authorities further divide this genus into three, splitting off the smooth-fronted caimans into a genus Paleosuchus and the Black Caiman into Melanosuchus.

Formerly, Sauer ( 1955 ) classified the genus into two subgenera, differentiating only between monoecious and dioecious species: Acnida ( L .) Aellen ex K. R.

At the time both South African and South American plants were placed in the same genus ; subsequently they were separated into two different genera.

The Bacillus-specific study with the most diversity covered is by Xu and Cote ' using 16S and the ITS region, where they divide the genus into 10 groups, which includes the nested genera Paenibacillus, Brevibacillus, Geobacillus, Marinibacillus and Virgibacillus.

In 1816, in the third volume of Lorenz Oken's Lehrbuch der Naturgeschichte, the author found sufficient similarities in the dentition of coyotes and jackals to place these species into a new separate genus from Canis called Thos after the classical Greek word θώς ( jackal ).

Nearly all the descriptive words used to justify the genus division were relative terms without a reference measure, and the argument did not take into account the size differences between the species, which can be considerable.

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

The early bipedals eventually evolved into the Australopithecines and later the genus Homo.

The early bipedals eventually evolved into the Australopithecines and later the genus Homo.

From these early species the Australopithecines arose around diverged into robust ( also called Paranthropus ) and gracile branches, one of which ( possibly A. garhi ) probably went on to become ancestors of the genus Homo.

As reported in the journal Science, testing of mitochondrial and nuclear DNA by Warren Johnson and Stephen O ' Brien of the U. S. National Cancer Institute demonstrated that ancient cats evolved into eight main lineages that diverged in the course of at least 10 migrations ( in both directions ) from continent to continent via the Bering land bridge and Isthmus of Panama, with the Panthera genus being the oldest and the Felis genus being the youngest.

The layout presented here follows the recent decades ' molecular phylogenetic studies, and takes into account the traditional splitting of the genus Carduelis.

The subfamily Homininae can be further subdivided into three tribes, each with only a single living genus: Gorillini ( gorillas ), Panini ( chimpanzees ), and Hominini ( humans and their extinct relatives ).

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.
