Question

why vermiform Appendix in humans is not used

Answer 1

The function of the vermiform appendix in the human body is not fully established yet. Scientists believe that it is a vestigial remnant, that is, it was once useful to humans in the digestion of food, but as we have evolved, it has lost its function and become redundant.

Answer 2

vermiform appendix is now an vestigeal organ which was used by our ancestors but as humans evolved it became of no use to them and was reduced as the vestiges.....like coccux, nictitating membrane in eye
