The binomial name is of Greek origin ; Phylloscopus comes from phyllon / φυλλον, " leaf ", and skopeo / σκοπεω, " to look at " or " to see ", since this genus comprises species that spend much of their time feeding in trees, while collybita is a corruption of kollubistes, " money changer ", the song being likened to the jingling of coins.

The family of Balaenids, therefore, comprises the right whales ( genus Eubalaena ), and in a genus all to its own, the very closely related bowhead whale ( genus Balaena ).

However, the tree constructed by the living tree project, a collaboration between ARB-Silva and LPSN where a 16S ( and 23S if available ) tree of all validated species was constructed, the genus Bacillus contains a very large number of nested taxa and majorly in both 16S and 23S it is paraphyletic to Lactobacillales ( Lactobacillus, Streptococcus, Staphylococcus, Listeria, etc.

While clearly attributable to the presence of the opportunistic pathogens of the genus Candida, candidiasis describes a number of different disease syndromes that often differ in their causes and outcomes.

Despite a large number of Homo fossils finds, chimpanzee fossils ( genus Pan ) were not described until 2005.

It is the only extant member of the genus Cuon, which differs from Canis by the reduced number of molars and greater number of teats.

For closed ( orientable or non-orientable ) surfaces with positive genus, the maximum number p of colors needed depends on the surface's Euler characteristic χ according to the formula

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.

It is the sole living representative of its family ( Ornithorhynchidae ) and genus ( Ornithorhynchus ), though a number of related species have been found in the fossil record.

For instance, power laws are thought to characterize the behavior of the upper tails for the popularity of websites, the degree distribution of the webgraph, describing the hyperlink structure of the WWW, the net worth of individuals, the number of species per genus, the popularity of given names, Gutenberg – Richter law of earthquake magnitudes, the size of financial returns, and many others.

The genus Sus is currently considered to have 10 living species and a number of extinct species known as fossila:

* Phoebis, a genus of Coliadinae that is not itself called the Sulfurs but that contains a number of species which are

The genus contains at least 68 described extant taxa, but the true number of species is a matter of debate.

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.

Cod is also used as part of the commons name for a number of other fishes, and there are species suggested to belong to genus Gadus that are not called cod ( the Alaska pollock ).

The term is widely needed to support the more esoteric requirements of a number of disciplines including in philosophy when a concept is not available ; in biology when a genus is not available ; in law when a special and unique interpretation of a case or authority will be needed on-the-fly ; in town-planning where there is no existing use-case ; in intellectual property rights where there is no defining characteristic ; and in politics and societal norms where there is no real authority perceived.

A species that is the lone extant member of its genus ( e. g. the Homo genus ) is not necessarily sui generis: extinction processes may have eliminated any number of species for which the genus was created.

The genus is unusual in that species throughout the genus, even those coming from different continents, can frequently be hybridized with each other, and this has led to an enormous number of cultivars.

The genus Allium also contains a number of other species variously referred to as onions and cultivated for food, such as the Japanese bunching onion ( A. fistulosum ), Egyptian onion ( A.
