The wings of insects, birds, and bats evolved independently but carry out similar functions. this is an example of a. analogous structures. b. embryonic structures. c. vestigial structures. d. homologous structures.

Analogous structures

Explanation:

Analogous structure may be defined as the structures that do not have similar origin but perform same functions.

The wings of birds, bats and insects evolve independently but have same superficial structure and performs same function. Thus, they are the example of analogous organ.

Thus, the correct answer is option (A).
