Question

From the given options find out the correct option that includes the example of vestigial structures in man.
A. A wisdom tooth, vermiform appendix, hair
B. A wisdom tooth, vermiform appendix, coccyx
C. A wisdom tooth, head, nails
D. None of the above

Answer 1

Hint: Vestigial structures in man have no apparent function and seems to be a residual part from a past ancestor. Vestigial organs represent the remnant characters that were once present in the ancestor but now are of no use.

Complete answer: Given, a combination of various structures that can be vestigial in the man.
Before beginning the answer, we should understand the Vestigial structures. Vestigial structures are generally the anatomical structure or behavior that serves no purpose in the current human life form.
These structures must have been of some use in the ancestral human beings and with the evolution, it is believed a stage will come when the vestigial structure will disappear and the structures that are useful to the man now might become of no use for the forthcoming generation.
This process takes thousands of years and can not be visualized by a single person.
Charles Darwin, the first pioneer to see life forms from a different perspective, also agreed on the presence of vestigial structure as evidence for the evolution process that is going on since the beginning of life form on this earth.
The most characteristic vestigial organs in man are as follows-
1. Appendix
2. Coccyx also called as the tailbone
3. Erector pili
4. Excessive body hair
5. Wisdom teeth

Therefore, the correct answer is option B.

Note: The most characteristic vestigial organs in man are Appendix, coccyx also called tailbone, erector pili, excessive body hair, and wisdom teeth.
