Question

Om what is the natural method of animal classification based?

Answer 1

Natural classification recognises three types of views, such as:

(i) Phenetic classi­fication

ii) Cladistic classification and

(iii) Evolutionary classification.

Answer 2

When a classification is constructed on the basis of a few external characters, even a single arbitrarily chosen character and with­out their relationships, called artificial type of classification.
The early taxonomists fol­lowed artificial type of classification up to 18th century, e.g., Aristotle (384-322 B.C.), Pliny (A. D. 23-79), Linnaeus (1707-’78), Georges Cuvier (1769-1822) and others. It is a downward classification and totality of characters is not considered.
