Question

Wings of kiwi and vermiform appendix in man are

• A. Homologous organs
• B. Analogous organs
• C. Vestigial organs
• D. None of the above

Answer 1

The correct option is C Vestigial organs

Analogous organs are those that perform similar functions but have entirely different embryonic origins. An example of an analogous organ would be the arms and legs of tetrapods (amphibians, reptiles, birds and mammals) and the "legs" of insects. Wings of kiwi and vermiform are not examples of analogous organs. Thus, option B is wrong.
The structure, which are similar in their morphology, anatomy, genetics and embryology but dissimilar in their function are called as homologous organs. Wings of kiwi and vermiform are not examples of homologous organs. Thus, option A is wrong.
Wings of kiwi and vermiform appendix are not functional in man. Thus, option D is wrong.
Vestigial organs are organs in an organism that are no longer necessary. Wings of kiwi and vermiform appendix are not functional in man. Thus, option C is correct.
