Question

Systematics is ?

Answer 1

Hint: The diversity of flora and fauna on earth led to the development of certain classification systems by scientists, which helped in the identification and understanding of their relationships with other organisms. Several scientists developed several classification systems and Systematics is one of them.

Complete answer:
Systematics is a method of classification of organisms based on their diversities and the relationships among them. The term Systematics is derived from the ‘Systema Naturae’ which was proposed by the scientist Carl Linnaeus in his book. He defined Systematics as the discipline of biology which explicitly focuses on the natural variation and relationship of organisms.
It has further three branches-
$1)$ Numerical Systematics- This is also known as Biometry, where biological statistics are used to identify and classify animals.
$2)$ Biochemical Systematics- This type of Systematics classifies and identifies animals based on the cell constituents such as the nucleus, cell organelles, and cytoplasm.
$3)$ Experimental Systematics- This type of Systematics classifies and identifies animals based on evolutionary units in a particular species. Mutation, genetic divergence, and hybridization are all considered evolutionary units.

Note:
Bioinformatics is a different part of biology which is based on the changes in species. It is completely different from systematic, where classification is done based on anatomy, ecology, physiology, genetics and biochemistry, embryology, morphology, and cytology. Also, the remnants of fossils and ecological relationships come under Systematics.

Additional information:
Identification is the first part of systematic, that provides a proper name and position to the organism. It divides the organism into different groups and taxonomy. Then nomenclature gives a scientific name to the organisms. Next comes taxonomy, which is ranking the classification.
