Question

Binomial nomenclature was first introduced by
A. Carolus Linnaeus
B. Ernst Haeckel
C. Gaspard Bauhin
D. John ray

Answer 1

Hint:-Binomial nomenclature is a systematic method for naming species of living organisms by assigning each one a name consisting of two parts, all of which use grammatical Latin forms, but they may be based on other language words.

Complete answer:
The Gaspard and Johann Bauhin brothers, Swedish botanists who lived from the mid-1500s to the early 1600s, created an early version of the naming method. There was a basic classification scheme, but it was the first of its sort to classify plants into "herbs," "trees," and "shrubs," and then split the groups according to how the plant is used. However, the key contribution of this work was his concept of identifying plants using a genus and/or organisms.
Another Swedish botanist, Carl Linnaeus (also known as Carl von Linné), who was born about 100 years after the death of the Bauhin brothers, is also given credit with developing the binomial nomenclature system. In practise, Linnaeus accepted their work and is responsible for the systematic implementation into the scientific world of the naming method. Later, the first work to systematically use a binomial nomenclature scheme composed of what Linnaeus considered a "trivial name" accompanied by a generic name was Linnaeus' 1753 publication Species plantarum. The frivolous name is now considered the species' special epithet or specific name. Many of the genus names produced by the Bauhin brothers were used by Linnaeus to develop the trivial names he used in his work.
From these discussions we can conclude that Carolus Linnaeus is the one who first introduced Binomial nomenclature. Therefore the correct answer is option (A).

Note:- Currently, two international codes of laws, the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for Algae, Fungi and Plants (ICN), govern the scheme of binomial nomenclature. While these two codes have similar basic concepts underlying binomial nomenclature, there are certain variations, both in the language they use and in their particular laws.
