Question

Which one of the following statements is not true?

• A. Flippers of whales and dolphins are homologous organs.
• B. Homologous organs have similar anatomical structure, but perform different functions.
• C. Homology indicates common ancestry.
• D. Homologous structures are a result of convergent evolution.

Hint:

Homologous structures result from common ancestry, while analogous structures arise from convergent evolution, leading to similar functions.

Answer 1

The Correct Option is D

Similarities in homologous structures stem from common descent, contrasting with convergent evolution, which results in analogous structures. Analogous structures, while functionally alike, evolve separately.
