In the human body all the given organs are vestigial except:
Correct answer: B. Leg muscles
- A. Appendix
- B. Leg muscles
- C. Coccyx
- D. Nictitating membrane
Explanation
Vestigial organs are rudimentary anatomical structures that are retained in a species despite having lost their primary ancestral function. These structures often lack an apparent purpose, in contrast to the full functionality of these organs observed in closely related and ancestral species.

About Concept of Evolution
Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
