When is binomial nomenclature used




















History The adoption of a system of binomial nomenclature is due to Swedish botanist and physician Carolus Linnaeus — who attempted to describe the entire known natural world and gave every species mineral , vegetable or animal a two-part name.

However, binomial nomenclature in various forms existed before Linnaeus, and was used by the Bauhins, who lived nearly two hundred years before Linnaeus. Before Linnaeus, hardly anybody used binomial nomenclature. After Linnaeus, almost everybody did.

Value of binomial nomenclature The value of the binomial nomenclature system derives primarily from its economy, its widespread use, and the stability of names it generally favors: Every species can be unambiguously identified with just two words. The same name can be used all over the world, in all languages, avoiding difficulties of translation.

Although such stability as exists is far from absolute, the procedures associated with establishing binomial nomenclature tend to favour stability. For example, when species are transferred between genera as not uncommonly happens as a result of new knowledge , if possible the species descriptor is kept the same. Similarly if what were previously thought to be distinct species are demoted from species to a lower rank, former species names may be retained as infraspecific descriptors.

Despite the rules favoring stability and uniqueness, in practice a single species may have several scientific names in circulation, depending largely on taxonomic point of view see synonymy. A major source of instability is the resurrection of forgotten names, which can claim priority of publication. In this case, however, conservation according to the nomenclature Codes is possible. Codes of nomenclature From the mid nineteenth century onwards it became ever more apparent that a body of rules was necessary to govern scientific names.

These Codes differ. The starting points, the time from which these Codes are in effect retroactively , vary from group to group. In botany the starting point will often be in the year Carolus Linnaeus first published Species Plantarum , in zoology in Bacteriology started anew, with a starting point in A BioCode has been suggested to replace several codes, although implementation is not in sight. Membrane Structure 4. Membrane Transport 5. Origin of Cells 6.

Cell Division 2: Molecular Biology 1. Metabolic Molecules 2. Water 3. Protein 5. Enzymes 6. Cell Respiration 9. Photosynthesis 3: Genetics 1. Genes 2. Chromosomes 3. Meiosis 4. Inheritance 5.

Genetic Modification 4: Ecology 1. Energy Flow 3. Carbon Cycling 4. Carl Linnaeus, the father of modern taxonomy and methods of classification, was the one who formalized the binomial nomenclature as the modern system of naming organisms. He designed the system so as to differentiate species from one to the other.

In his book, Systema Naturae , he described and classified thousands of species of plants and animals. Soon, he had to track his classifications and to do that he came up with a concise naming system leading to the several binomial labels of species that he consistently used in his work, and eventually were applied and popularized in the scientific community.

Although Carl Linnaeus was credited for the modern two-term naming system, his work was largely influenced by that of Gaspard Bauhin, together with his brother, Johann Bauhin. The Bauhin brothers were using the binomial nomenclature almost years earlier. Many of the generic names introduced by them were adopted by Linnaeus. Binomial nomenclature proved to be essential in the scientific community. Through this system, taxonomists from all around the world can identify a species in unison.

Unlike the common names that can differ from one language to another, a scientific name proved to be more consistent. Not only will scientists and taxonomists evade inconsistency issues but they can also have an idea of the genus through which a species belongs, and therefore, have an idea of the attributes that members of the genus share. Thus, it is not surprising that the scientific community continues to adopt a naming system to this day. They provide guidelines for the proper citation of animal binomial names.

The International Code of Nomenclature for algae, fungi, and plants ICNafp is the code that sets the botanical names of plants, including algae and fungi. It is formerly known as the International Code of Botanical Nomenclature. These governing systems or codes operate independently of one another.

Because of this, they could use generic names for animals that are already in use for plants. Thus, there are instances when the genus of a plant is encountered in animals although the two species are obviously unrelated phylogenetically. Tautonym, where the generic name and the specific name are the same, is not allowed in ICNafp. However, it is permitted in ICZN. The main objective of these codes is to provide a name that can be consistently used for a species that is perceptible.

Animals, for example, that are within the confines of mythology will, therefore, fail to meet the criteria of being given a scientific name.
