Question

Which of the following pairs is/are analogous structures?

• A. Human hands and bat wings
• B. Butterfly wings and bat wings
• C. Bat wings and bird wings
• D. Dolphin flippers and fish fins

Hint:

{Homologous} = common ancestry, different function. {Analogous} = different ancestry, same function.

Answer 1

The Correct Option is B, C, D

Step 1: Recall the definition.
Analogous structures perform similar functions but have different evolutionary origins.
Step 2: Analyze options.
(A) Human hands and bat wings → homologous (same origin, different function).
(B) Butterfly wings (insects) and bat wings (mammals) → analogous (different origin, same function).
(C) Bat wings and bird wings → analogous (different evolution, same purpose).
(D) Dolphin flippers and fish fins → analogous (aquatic adaptation, different origin).
Step 3: Conclusion.
The best example of analogy among given options is (B) butterfly wings and bat wings.
