Binomial Nomenclature


The binomial nomenclature system was introduced by Carl Linnaeus. Many local names make it very difficult to identify a species on a global scale and to track the number of species. Thus, it creates great confusion. To eliminate this confusion, a common protocol has emerged. According to it, every living thing will have the same scientific name that everyone will use to identify a living thing. This common naming process is called Binomial Nomenclature.

    All living things including plants, animals, birds, and other germs have their own scientific names.


    • The scientific name of the tiger is derived from the Panthera tigris. ‘Panthera’ represents a genre and ‘Tigris’ represents a genus or a specific epithet.
    • The human scientific name is expressed as Homo sapiens. ‘Homo’ represents a species and ‘sapiens’ represents a genus.
    • The Indian bullfrog is scientifically named Rana tigrina. ‘Rana’ is a genus name and ‘tigrina’ is a genus.


    A biologist worldwide follows a set of similar principles for designing living things. There are two international codes agreed upon by all biologists around the world regarding the naming process. Of course:

    • International Code for Plant Genetics and Plant Enlargement (ICBN) – Contains the name of plant species.
    • International Code of Zoological Nomenclature (ICZN) – deals with animal biological nomenclature.
    • These codes ensure that each organism receives a specific name and that name is identified worldwide.

    Naming conventions follow certain rules. Each scientific name has two parts:

    • Generic Name
    • Specific epithet

    Other binomial nomenclature rules for writing biological words include the following:

    • All biological words are usually Latin. Thus, they are written in italics.
    • There are two parts to the word. The first word identifies the type and the second identifies the type.
    • If the words are handwritten, underlined or italics if written. This was done to clarify its Latin origin.
    • The type name starts with a capital letter and the type name starts with a lowercase letter.


    As mentioned earlier, millions of species of living things are being distributed worldwide. In addition, similar organisms are known by different names throughout the world and this can cause confusion when trying to identify or distinguish them. Therefore, binomial nomenclature was seen as an effective solution to this problem.

    Wrong for Naming Two Names

    Some of the main barriers to binomial nomenclature are:

    If two or more words are used in accordance with the law of value, the correct word will be used first and the others end up synonymous because authenticity is the same as greater. This should be emphasized to ensure consistency in the design and classification of species.

    The names used by Linnaeus before those included in “Systema Naturae” are also not recognized.


    Commonly known as consecutive nomenclature, this systematic form of living organisms has two Latin names, species, and species. All living things, including other germs, have a scientific name.

    • We should summarize the benefits of the binomial scheme as follows:
    • It is simple and very accurate in its similarity. In this case, all sorts are the same in a simple way.
    • The gist is expandable and may indicate the names of some organisms which can be used in the future.
    • It provides a description of our relationship, which serves as a helper.
    • Memory also provides basic plant information that we can know about.
    • It makes it easy to talk about groups of species that have certain common characteristics.

    Carl Linnaeus introduced the concept of binomial nomenclature. Many place names make it difficult to identify a global species and to track the number of species. And it causes a lot of uncertainty. A law has been issued to remove that confusion. According to it, every living thing can have one scientific name that everyone can use to distinguish a living thing. This systematic formulation is known as Binomial Nomenclature. Well-known living things have common names. You are probably familiar with, for example, small red insects with tiny black dots. You can call them ‘ladybugs’ or ‘ladybird beetles.’ But did you know that these insects are actually several different species? Just using common words will make it difficult for scientists to distinguish between them, so each species gets its own scientific name.
