- Systematics plays an important role in the field of biology.
- Carl Linnæus is the father of Systematics.
- Systematics refers to the study of the diversification,nomenclature, and classification of the living organism in the past and also in present.
- Systematics is used to understand the evolutionary relationship and the purpose of systematics is to describe and explain biological variety.
- The main objective of systematics is to identify species and to give scientific names to organisms, it used to determine the arrangement of the living organism and to study the evolutionary history of organisms.
