Finger [1]

Answer :3. similarities among vertebrate forelimbs suggest that they evolved from a common ancestor.

Explanation:

The study of differences and similarities in the anatomy of different species is comparative anatomy. It is based on the concept that  

1.)Homologous structures  which are present in different species, because they have a common decent and must have evolved  divergently from a shared ancestor. Theses anatomic structures may not be used for the same purposes. For example the forelimb of fox and whale.

2. Some  structures (Analogous)which are similar in different organisms must have evolved  ,(acquired through natural selection) through convergent evolution in similar environment,  and not inherited from a recent ancestor. These organisms usually use these structures for a common purpose. For example the streamline body shape   of shark and porpoises, which though are used for a common purpose of swimming, were inherited from different ancestors.

.  Example  of comparative anatomy is the common  bone structures in forelimbs of fox, whales, bats, and humans. These appendages is made up of  the same basic parts; despite serving  different functions.  

Comparative anatomy helps scientists in classification of organisms based on their similar characteristics of their anatomical structures.
