Text Solution

Verified by Experts
The correct answer is:
B

• Analogous organs: These are organs that perform the same function but have different origin and structure.

• Example: Wings of locust (insect), bat (mammal), sparrow (bird), and flying fish (fish).

• All are used for flight, but their anatomical structures and evolutionary origins are different.

• Homologous organs: Same structure and origin, but may perform different functions (e.g., forelimbs of horse, whale, bat, and man).

• Atavism: Reappearance of ancestral characters.

• Vestigial organs: Organs that have lost their original function (e.g., appendix in humans).
