Comparative Anatomy is to make a comparative study of the anatomy of an organ in different groups of vertebrates and try to derive the evolutionary significance from it, and to understand as to why an organ evolved the way it is present now. This mode of cla ssification is defined exclusively by ages during the evolution of vertebrate skeletal systems.
