Question

On what basis the New Systematics differs from classical systematics? Mention about the various approaches which are adopted for classification under New Systematics.

Answer 1

New systematics differs from classical systematics in various ways. These are:

1. Species are classified on the basis of cytology, physiology, biochemistry, and ecology rather than morphology.

2. Species are not static but are highly dynamic.

3. Species does not occupy the central position in the work of systematics. In new systematics, the focus has shifted to sub-species and populations.

4. Experimental variability is used to measure various parameters. Statistical data is incorporated to understand primitiveness, inter-relationships, and advancements between species.
