Question

The taxonomy includes
A. Classification
B. Nomenclature
C. Identification
D. All of the above

Answer 1

Taxonomy is the science of classification of living and extinct organisms based on their characteristics.

Complete answer:
Option A: Taxonomy includes the classification of biological organisms based on shared characters. But taxonomy is not the classification alone. Therefore, this is the incorrect option.
Option B: Taxonomy includes the binomial nomenclature of organisms identified. But taxonomy is not the nomenclature alone. Therefore, this is the incorrect option.
Option C: The first step of taxonomy is the identification of species. The taxonomy also includes further processes. Therefore, this is the incorrect option.
Option D: Taxonomy is the scientific study of identifying, naming, defining, and classifying groups of biological organisms. Therefore this is the correct option.
The first step of taxonomy is the collection of specimens. Once the specimen is collected, the next step is to identify the species. It checks whether the species is known or yet to be described with the help of existing taxonomic knowledge. After this, the organism is classified into different groups based on shared characteristics. A taxon is a group of organisms classified into one unit and these groups are given ranks based on their position in the hierarchy level. The ranks are domine, kingdom, phylum, class, order, family, genus, and species in descending order. This is followed by binomial nomenclature and finally the detailed characterization of the organism. Carl Linnaeus is known as the founder of the current taxonomy. Modern taxonomy uses database technology to document species.

Hence the correct answer is option ‘D’, all of the above.

Note: Modern biological classification is based on the evolutionary relationship between organisms. In a huge variety of species available on the face of the earth, taxonomy helps to pinpoint the one species of our interest because of the organized arrangement of these species. The unique naming of species has made communication convenient irrespective of regional and language differences.
