Explain the utility of systematic and mention the characteristics of new
Systematics is defined as “the study of the classification of organisms based on evolutionary relationships”. (i)It provides useful information about organisms, their evolution and adaptation name and classification etc. (ii)Systematics helps us in the identification of useful and harmful animals or plants in the applied field of biology. (iii)It plays an economical role. New systematics has the following features:- (a)Species are regarded as dynamic units and not as static units of classical systematics. (b)Because much of the work is done with species subgroups, the value of species as a whole is diminished. (c)The morphological species definition has been replaced by a biological one that takes ecology, genetics, geography, cytology and behaviour into consideration.
