A report on Genus

Estimated accepted genus totals by kingdom - based on Rees et al., 2020
Number of reptile genera with a given number of species. Most genera have only one or a few species but a few may have hundreds. Based on data from the Reptile Database (as of May 2015).

Taxonomic rank used in the biological classification of living and fossil organisms as well as viruses.

Binomial nomenclature

Formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages.

Echinopsis pachanoi, the San Pedro cactus
Carl Linnaeus (1707–1778), a Swedish botanist, invented the modern system of binomial nomenclature
The bacterium Escherichia coli, commonly shortened to E. coli
Magnolia hodgsonii

The first part of the name – the generic name – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus.

All adult Eurasian blue tits share the same coloration, unmistakably identifying the morphospecies.

Species

Basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity.

All adult Eurasian blue tits share the same coloration, unmistakably identifying the morphospecies.
A region of the gene for the cytochrome c oxidase enzyme is used to distinguish species in the Barcode of Life Data Systems database.
The cladistic or phylogenetic species concept is that a species is the smallest lineage which is distinguished by a unique set of either genetic or morphological traits. No claim is made about reproductive isolation, making the concept useful also in palaeontology where only fossil evidence is available.
A chronospecies is defined in a single lineage (solid line) whose morphology changes with time. At some point, palaeontologists judge that enough change has occurred that two species (A and B), separated in time and anatomy, once existed.
A cougar, mountain lion, panther, or puma, among other common names: its scientific name is Puma concolor.

Ernst Mayr proposed the widely used Biological Species Concept of reproductive isolation in 1942.
Palaeontologists are limited to morphological evidence when deciding whether fossil life-forms like these Inoceramus bivalves formed a separate species.
Horizontal gene transfers between widely separated species complicate the phylogeny of bacteria.
John Ray believed that species breed true and do not change, even though variations exist.
Carl Linnaeus created the binomial system for naming species.
Blackberries belong to any of hundreds of microspecies of the Rubus fruticosus species aggregate.
The butterfly genus Heliconius contains many similar species.
The Hypsiboas calcaratus–fasciatus species complex contains at least six species of treefrog.

The first part of a binomial is the genus to which the species belongs.

The rules and recommendations have one fundamental aim: to provide the maximum universality and continuity in the naming of all animals, except where taxonomic judgment dictates otherwise.

The rules in the code determine what names are valid for any taxon in the family group, genus group, and species group.

The major ranks: domain, kingdom, phylum, class, order, family, genus, and species, applied to the red fox, Vulpes vulpes.

The next year, 1737, he published Genera Plantarum, in which he described 935 genera of plants, and shortly thereafter he supplemented it with Corollarium Generum Plantarum, with another sixty (sexaginta) genera.

Panthera

Two cladograms proposed for Panthera. The upper one is based on phylogenetic studies by Johnson et al. (2006), and by Werdelin et al. (2010). The lower cladogram is based on a study by Davis et al. (2010) and by Mazák et al. (2011).

Panthera is a genus within the family Felidae that was named and described by Lorenz Oken in 1816 who placed all the spotted cats in this group.
