Genus ( / ˈ dʒ iː n ə s / ; pl. : genera / ˈ dʒ ɛ n ər ə / ) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses . In binomial nomenclature , the genus name forms the first part of the binomial species name for each species within the genus.

There are five living species: the jaguar , leopard , lion , snow leopard and tiger , as well as a number of extinct species, including the cave lion and American lion . The word panther derives from classical Latin panthēra , itself from
142-486: A Privatdozent at Göttingen in 1806, knew nothing of this unpublished idea or discovery of Goethe, and that Goethe first became aware that Oken had the idea of the vertebral relations of the skull when he listened to the introductory discourse in which the young professor, invited by the poet to Jena, selected this very idea for its subject. It is incredible that Oken, had he adopted the idea from Goethe, or been aware of an anticipation by him, should have omitted to acknowledge
213-557: A species : see Botanical name and Specific name (zoology) . The rules for the scientific names of organisms are laid down in the nomenclature codes , which allow each species a single unique name that, for animals (including protists ), plants (also including algae and fungi ) and prokaryotes ( bacteria and archaea ), is Latin and binomial in form; this contrasts with common or vernacular names , which are non-standardized, can be non-unique, and typically also vary by country and language of usage. Except for viruses ,

In place of the "valid taxon" in zoology, the nearest equivalent in botany is " correct name " or "current name" which can, again, differ or change with alternative taxonomic treatments or new information that results in previously accepted genera being combined or split. Prokaryote and virus codes of nomenclature also exist which serve as

In it he extended to physical science the philosophical principles which Immanuel Kant (1724–1804) had applied to epistemology and morality. Oken had been preceded in this by Johann Gottlieb Fichte (1762–1814), who, acknowledging that Kant had discovered the materials for a universal science, declared that all that was needed was

For example, the World Register of Marine Species presently lists 8 genus-level synonyms for the sperm whale genus Physeter Linnaeus, 1758, and 13 for the bivalve genus Pecten O.F. Müller, 1776. Within the same kingdom, one generic name can apply to one genus only. However, many names have been assigned (usually unintentionally) to two or more different genera. For example,
568-409: A reference for designating currently accepted genus names as opposed to others which may be either reduced to synonymy, or, in the case of prokaryotes, relegated to a status of "names without standing in prokaryotic nomenclature". An available (zoological) or validly published (botanical) name that has been historically applied to a genus but is not regarded as the accepted (current/valid) name for
639-483: A representation of the sense-organs, and that they must be arranged in accordance with them." Consequently, Oken contended that there are only five animal classes: In 1805 Oken made a further advance in the application of the a priori principle in a book on generation ( Die Zeugung ), in which he maintained that "all organic beings originate from and consist of vesicles or cells. These vesicles, when singly detached and regarded in their original process of production, are
710-436: A systematic coordination of these materials. Fichte undertook this task in his "Doctrine of Science" ( Wissenschaftslehre ), whose aim was to construct all knowledge by a priori means. This attempt, which was merely sketched out by Fichte, was further elaborated by the philosopher Friedrich Schelling (1775–1854). Oken built on Schelling's work, producing a synthesis of what he held Schelling to have achieved. Oken produced
781-427: A taxon; however, the names published in suppressed works are made unavailable via the relevant Opinion dealing with the work in question. In botany, similar concepts exist but with different labels. The botanical equivalent of zoology's "available name" is a validly published name .

"Official" registers of taxon names at all ranks, including genera, exist for a few groups only such as viruses and prokaryotes, while for others there are compendia with no "official" standing such as Index Fungorum for fungi, Index Nominum Algarum and AlgaeBase for algae, Index Nominum Genericorum and

Black panthers do not form a distinct species, but are melanistic specimens of the genus, most often encountered in the leopard and jaguar.

Results of a 2016 study based on analysis of biparental nuclear genomes suggest the following relationships of living Panthera species: The extinct species Panthera gombaszoegensis , was probably closely related to the modern jaguar. The first fossil remains were excavated in Olivola , in Italy, and date to 1.6 million years ago . Fossil remains found in South Africa that appear to belong within

All Panthera species have an incompletely ossified hyoid bone and a specially adapted larynx with large vocal folds covered in a fibro-elastic pad; these characteristics enable them to roar . Only the snow leopard cannot roar, as it has shorter vocal folds of 9 mm (0.35 in) that provide a lower resistance to airflow; it was therefore proposed to be retained in the genus Uncia . Panthera species can prusten , which
1278-460: Is somewhat arbitrary. Although all species within a genus are supposed to be "similar", there are no objective criteria for grouping species into genera. There is much debate among zoologists about whether enormous, species-rich genera should be maintained, as it is extremely difficult to come up with identification keys or even character sets that distinguish all species. Hence, many taxonomists argue in favor of breaking down large genera. For instance,

Should the specimen turn out to be assignable to another genus, the generic name linked to it becomes a junior synonym and the remaining taxa in the former genus need to be reassessed. In zoological usage, taxonomic names, including those of genera, are classified as "available" or "unavailable". Available names are those published in accordance with

The Lehrbuch procured for Oken the title of Hofrath , or court-councillor, and in 1812 he was appointed ordinary professor of the natural sciences. In 1816 Oken began publication of his well-known periodical, Isis, eine encyclopädische Zeitschrift, vorzüglich für Naturgeschichte, vergleichende Anatomie und Physiologie . In this journal appeared essays and notices on

2272-417: The explanation of all the mysteries of nature. According to him, the head was a repetition of the trunk—a kind of second trunk, with its limbs and other appendages; this sum of his observations and comparisons—few of which he ever gave in detail—ought always to be borne in mind in comparing the share taken by Oken in homological anatomy with the progress made by other cultivators of that philosophical branch of

Thus in the examples above, the genus Canis would be cited in full as " Canis Linnaeus, 1758" (zoological usage), while Hibiscus , also first established by Linnaeus but in 1753, is simply " Hibiscus L." (botanical usage). Each genus should have a designated type , although in practice there is a backlog of older names without one. In zoology, this

Also, as visible in the above examples, the Latinised portions of the scientific names of genera and their included species (and infraspecies, where applicable) are, by convention, written in italics . The scientific names of virus species are descriptive, not binomial in form, and may or may not incorporate an indication of their containing genus; for example,

Vaguely and strangely, however, as Oken had blended the idea with his a priori conception of the nature of the head, the chance of appropriating it seems to have overcome the moral sense of Goethe—unless indeed the poet deceived himself. Comparative osteology had early attracted Goethe's attention. In 1786 he published at Jena his essay Ueber den Zwischenkieferknochen des Menschen und der Thiere , showing that

But not a word in this essay gives the remotest hint of his having then possessed the idea of the vertebral analogies of the skull.

In Owen's Archetype and Homologies of the Vertebrate Skeleton the idea was not only revived but worked out for the first time inductively, and the theory rightly stated, as follows: "The head is not a virtual equivalent of the trunk, but is only a portion, i.e. certain modified segments, of the whole body. The jaws are the 'haemal arches' of the first two segments; they are not limbs of

However, some insect genera such as the bee genera Lasioglossum and Andrena have over 1000 species each. The largest flowering plant genus, Astragalus , contains over 3,000 species. Which species are assigned to a genus

However, a genus in one kingdom is allowed to bear a scientific name that is in use as a generic name (or the name of a taxon in another rank) in a kingdom that is governed by a different nomenclature code. Names with the same form but applying to different taxa are called "homonyms". Although this

He chose the latter alternative. The publication of Isis at Weimar

In 1809 Oken extended his system to the mineral world, arranging the ores, not according to the metals, but according to their combinations with oxygen, acids and sulphur. In 1810 he summed up his views on organic and inorganic nature into one compendious system. In

On their return to Göttingen, Oken explained his ideas by reference to the skull of a turtle in Kieser's collection, which he disarticulated for that purpose. Kieser displayed the skull, its bones marked in Oken's handwriting. Oken's lectures at Jena were wide-ranging, and were highly regarded at

The idea of the analogy between the skull, or parts of the skull, and the vertebral column had been previously propounded and ventilated in their lectures by Johann von Autenrieth (1772–1835) and Carl Kielmeyer (1765–1844), and in the writings of Johann Frank (1745–1821). By Oken it was applied chiefly in illustration of the mystical system of Schelling—the "all-in-all" and "all-in-every-part." From

The position advanced in that work, to which he continued to adhere, is that "the animal classes are virtually nothing else than

Genetic studies indicate that the pantherine cats diverged from the subfamily Felinae between six and ten million years ago. The genus Neofelis is sister to Panthera . The clouded leopard appears to have diverged about 8.66 million years ago . Panthera diverged from other cat species about 11.3 million years ago and then evolved into

Mitochondrial sequence data from fossils suggest that the American lion ( P. atrox ) is a sister lineage to Panthera spelaea (the Eurasian cave or steppe lion) that diverged about 0.34 million years ago , and that both P. atrox and P. spelaea are most closely related to lions among living Panthera species. The snow leopard

The specific name is written in lower-case and may be followed by subspecies names in zoology or a variety of infraspecific names in botany . When the generic name is already known from context, it may be shortened to its initial letter, for example, C. lupus in place of Canis lupus . Where species are further subdivided,
4189-412: The standard format for a species name comprises the generic name, indicating the genus to which the species belongs, followed by the specific epithet, which (within that genus) is unique to the species. For example, the gray wolf 's scientific name is Canis lupus , with Canis ( Latin for 'dog') being the generic name shared by the wolf's close relatives and lupus (Latin for 'wolf') being

#17327733594334402-596: The title, Ueber die Bedeutung der Schädelknochen . With regard to the origin of the idea, Oken narrates in his Isis that, walking one autumn day in 1806 in the Harz forest , he stumbled on the blanched skull of a deer, picked up the partially dislocated bones, and contemplated them for a while, when it suddenly occurred to him, "It is a vertebral column!" At a meeting of the German naturalists held at Jena some years afterwards, Professor Kieser gave an account of Oken's discovery in
4473-419: The universe's activities within a single individual body." This doctrine led him to the conviction that "world and organism are one in kind, and do not stand merely in harmony with each other." In the same year he published his Erste Ideen zur Theorie des Lichts, &c. , in which he advanced the proposition that "light could be nothing but a polar tension of the ether, evoked by a central body in antagonism with

Within Animalia, the largest phylum is Arthropoda , with 151,697 ± 33,160 accepted genus names, of which 114,387 ± 27,654 are insects (class Insecta).
