Binomial Nomenclature-Everything you need to know

Binomial Nomenclature is actually a formal system of labeling or naming species of all living things.

Binomial Nomenclature helps in keeping all our known different species of all living things in an organized system.


The following information is provided. According to binomial nomenclature, what is the organism’s name?

Kingdom: Animalia

Order: Passeriformes

Class: Aves

Phylum: Chordata

Genus: Hylcocichla

Family: Turdidae

Species: Mustelina


Binomial nomenclature was invented by



Binomial Nomenclature is a formal system that’s used worldwide.

All species are given a 2-part name which is based on the grammatical form in Latin, though the words we use may come from some other language as well and many of these names have their roots in Greek.

The first part of the Binomial Nomenclature name is indicating to which “digenous” that species is belonging to while the second part of the Binomial Nomenclature indicated the species within “digenous”. An example: humans are belonging to the “digenous” homo and to the species “sapiens”. S we are referred to as “Homo sapiens”.

Note also how it is written. The entire name is here written in italics. Now, here we have a normal text but if we had the Binominal Nomenclature, so the scientific, formal name of any species in an italicized sentence or in an italicized paragraph, then we would have to put, just that part, just that scientific name, in the Roman typeface, just to make it stand out from the rest of that sentence or paragraph.

In normal text, however, we would italicize the entire scientific name, both digenous and the species written in italics with the digenous (the first part) capitalized while the second part (the species) would be put in lower case.

In “Homo sapiens”, we have an example of “genus” and “species”. The genus is capitalized, the species is in lower case and the entire name is written in italics unless we’re faced with is a situation where the paragraph or the sentence is already italicized. Then we need to set it off from the rest by using the Roman typeface.

The Binominal Nomenclature, the 2-part naming system for all living things, was thought up by Swedish naturalist Carl Nance who introduced this system formally in 1753. The rest if the world also picked it up and it has been around ever since. Just think about the number of different plants and animals there are. Wouldn’t it be hard to keep track of or organize all these different things in the world if we wouldn’t have some sort of formalized naming system?

Because the grammatical form of the Binominal Nomenclature system is founded on Latin and many of the names have Latin or Greek roots, those names will be the same all across the world. Because Latin and ancient Greek are dead languages, this will not change or evolve so the names will always be the same.

If you would have a certain name for a specific plant or creature in your yard and in a few states further down or in another country someone else would have a different common name for that plant or creature, things would get complicated and it would be really hard to tell whether we’re all talking about exactly the same animal or plant, don’t you think? But by using the Binominal Nomenclature, this 2-part naming system, all these things will have the same scientific name. We all will be able to talk about the same plants in our back yards or be surprised that in another country, they have the same thing.

All across the globe, scientists are able to communicate with one another and tell each other what species they’ve found since they all use the same formal naming system. This will also eliminate confusion about creatures with identical common names. For example, swifts can be lizards, birds, or foxes. If we take the scientific name, however, the Binominal Nomenclature, genus an species of these creatures will be different.

Sure, the fox, the lizard, and the bird may all be referred to as a swift for a common name, but they’ll not have identical genus or species. They’re going to be all very different if we use the Binomial Nomenclature, the 2-part international naming system that helps to keep everyone and everything well-organized and right on the same page, wherever in the world we are.
