Explanation

Homologous Organs: These organs have similar anatomical structures but perform different functions.

They are the result of divergent evolution.

A human's arm, a dog's leg, a bird's wing, and a whale's flipper are all homologous. The same bones are found in each structure; they only differ in their size and shape.
