Which of the following is considered a vestigial organ in humans?
- A.Nictitating membrane
- B.Heart
- C.Lungs
- D.Kidney
Show correct answer & step-by-step solution
Correct answer: A — Nictitating membrane
Solution
- Vestigial organs are structures that have lost their original ancestral function during evolution.
- In humans, the nictitating membrane is present as a small fold in the corner of the eye.
- It does not serve the protective function it performs in other vertebrates.
- Hence the answer is (A).
