Origin & Purpose of Scientific Names Every recognized species on earth (at least in theory) is given a two-part scientific name. This system is called "binomial nomenclature." These names are important because they allow people throughout the world to communicate unambiguously about animal species and plant species.

Why is it important to have rules for naming species?
It is important to have rules for naming species using binomial nomenclature (also called binomial, binominal or binary names) so that everyone does it in a uniform way to create brief and unique names that can be used and understood worldwide. The International Code of Zoological Nomenclature and the International Code of Nomenclature for Algae, Fungi and Plants are the two main governing bodies that establish and enforce the rules for binomial nomenclature. There are some specific rules for certain naming situations, but below is a summary of the major ones.
What is the gender of a species name?
The species name always begins with a lower case letter. It can be a noun or an adjective and it must agree with the Latin gender of the genus name; masculine, feminine or neuter. For example, if the gender of the genus is masculine, the species name should end in -us, -a or -um. An example of this is Passer domesticus, the house sparrow, in which Passer has a masculine gender. Endings for feminine species names include -is and -e and -or is used for neuter genders.
What is a genus name?
The Genus. The genus name is also called the generic name and always begins with a capital letter. For example, binomial name for cats is Felis catus. The genus name must be unique within each kingdom (see image below) but the same genus can be used in more than one kingdom.

Which classification uses binomial nomenclature as its base?

What is the scientific name for Homo sapiens?
The scientific name Homo sapiens is used to describe the human species. It combines parts of the Latin words hom, meaning human, and sapien, meaning wise. This descriptor of humans tells us many things about the species. First and foremost it defines humans as part of the genus Homo, which includes several extinct species of early humans and modern humans. While we are the only living species in the genus Homo, the specific epithet describes our supposed separation from other species in the genus. Homo neaderthalensis for example, is hypothesized to have gone extinct because of competition from Homo sapiens, or modern humans. Many theorize that it was advanced tool use and language in Homo sapiens that gave them an edge. Modern DNA analysis has shown that Neanderthal genes still exist within the human population, suggesting the two may have interbred at certain points. The binomial nomenclature used here serves to clarify between different forms of organisms through evolutionary time, as well as clarify that all humans are being discussed.
Why is binomial nomenclature important?
Although a species may lose some or most of its ancestral characteristics, binomial nomenclature makes it easier to keep track of these relationships in the larger context of taxonomy. In some organisms, the species are divided into even smaller subspecies, which are presented after the species name.
What is the term for the taxonomic hierarchy of organisms?
The generic epithet of binomial nomenclature refers to the taxonomic hierarchy of organisms, genus, of each organisms. This is a clue as to the origins, evolution, and life-history of the organism. Genera, which reside in families, share the traits of those families. In turn, families reside within orders, which also have their own characteristics. This continues up the hierarchy, all the way to the 4 domains of life, which are each distinguished by their own characteristics. Although a species may lose some or most of its ancestral characteristics, binomial nomenclature makes it easier to keep track of these relationships in the larger context of taxonomy.
How to write a scientific name?
The second word is the specific epithet and refers to the species of the organism. Typically, the words have a Latin base and describe the genus or species with references to traits that are specific to the group. When written, the text of a scientific name is usually italicized or underlined, to clarify that it is a scientific name written in binomial nomenclature. The generic epithet is always capitalized, while the specific epithet is written in lower-case. In some older documents, both may be capitalized. Typically, the full name should be written out. However, when discussing many species of the same genus, the generic name is sometimes abbreviated to the first letter, still capitalized.
