Question

Which among the following statements are correct with respect to homologous organs?

• A. They perform same function.
• B. They are structurally similar.
• C. They indicate common ancestory.
• D. (b) and (c) above.

Answer 1

The correct option is D (b) and (c) above.

The organs which have the same fundamental structure but are different in functions are called homologous organs. Here the organs are modified to perform different functions as an adaptation to different environments. Homologous organs indicate common ancestory. E.g., forelimbs of man, cheetah, whale and bat. They have the same basic structural plan. But are modified to perform different functions.
