The scientific name is how species of any living organism are named by biologists. Is follows the binomial nomenclature, that is to say the name of a species is made of two parts: one indicating the genus and one indicating the species. Binomial nomenclature means "two-part name" or "system of two-part names".

It is made of Latin words or at least Latinized words that are not real Latin and may come from another language.

History[edit | edit source]

The person who popularized this system for use was Swedish botanist and physician Carolus Linnaeus (1707–1778)[1] who tried to name all things in the natural world and gave every species (animal, vegetable or mineral) that he knew a two-part name. This kind of naming had been used before Linnaeus, but before Linnaeus, almost nobody used binomial nomenclature. After Linnaeus, about everybody did.

Value of binomial nomenclature[edit | edit source]

The value of the binomial nomenclature comes from its economy, its widespread use, and the uniqueness and stability of names in the system. The system replaced the use of Latin descriptive names, which were not handy as they were long (and growing all the time).

An important reason for the stability of names is that they need not be descriptive. For example, Simmondsia chinensis has the component chinensis which means "from China"; this was used in error, as the species is from California. Nevertheless, this name is used worldwide and is not to be 'corrected'. In today's system of naming, a name is just a label, and remains stable even if it is misdescriptive. Of course, ideally names should be descriptive; this makes it easier to remember them: Populus alba has leaves which are white underneath (alba means "white").

Where names come from[edit | edit source]

The components of a name may come from any source whatsoever. Often they are Latin words, but they may also come from Ancient Greek, from a place, from a person, a name from a local language, etc.

The names themselves are always treated grammatically as if they were a Latin sentence. This is why the name of a species is sometimes called its "Latin name," but scientists like calling these names scientific names.

The genus name must be unique inside each group of life. Species indicators need not be unique, but of course may not be used twice within the same genus.
