Question

Which of the following is a vestigial organ in the human body?

• A. Eyelid
• B. Eyelash
• C. Caecum
• D. Appendix

Answer 1

Answer: (D)

• Vestigial organs are the structures which have no apparent function in a particular organism perhaps once they did. They appear to be a residual part of a past ancestor.
• Charles Darwin listed a number of human vestigial organs, which he termed rudimentary, in The Descent of Man (1890). These included the muscles of the ear, wisdom teeth. the appendix, the tail bone, body hair, and the semilunar fold, in the corner of the eye.
  
• Hence Appendix is a vestigial organ in the human body.
• So, the correct answer is 'Appendix'.
