Question

Human arm is homologous with:

• A. Flippers of seal
• B. Wing of bird
• C. Both A and B
• D. Wing of insect

Answer 1

The correct option is C Both A and B

Anatomically, the human arm, the flippers of seals, and the wings of the birds are the forelimbs containing similar bones. These forelimbs have a common origin and similar anatomical features but have been modified to perform different functions. Flippers allow the seal to swim, birds fly using their wings and humans perform a variety of functions using the arms. Such structures are homologous to each other. The wings of insects are anatomically different.

Hence, the correct answer is option C.
