Question

Which of the following statements are correct? I) Homologous organs have the same structure but show different functions.
II) Homologous organs have common ancestors.
III) Analogous organs show divergent evolution.
IV) Wings of butterfly and birds are homologous.

• A. I, II and IV are correct
• B. I and II are correct
• C. II, III and IV are correct
• D. Only I and IV are correct

Hint:

\[ \boxed{\text{Homologous → same origin, different function}} \] \[ \boxed{\text{Analogous → different origin, same function}} \]

Answer 1

The Correct Option is B

Homologous organs share the same embryonic origin and basic structural plan but have diverged to perform different functions, such as the forelimbs of humans, bats, and whales, indicating divergent evolution. Analogous organs differ in origin and internal structure yet perform similar functions, such as wings of birds and insects, indicating convergent evolution from unrelated lineages.
