Detailed explanation-1: -Vestigial organs and body parts refer to those that have little or no purpose in humans. They are a vestige left over from our ancestors. We have more than 100 vestigial anomalies, the most renowned of which are the appendix, wisdom teeth, coccyx, external ear, and male nipples.

Detailed explanation-2: -Vestigial organs are organs, tissues or cells in a body which are no more functional the way they were in their ancestral form of the trait. It is authentication of evolution and hence, were helpful in explaining adaptation. Such a structure can arise due to gene mutation which causes a change in the proteins.

Detailed explanation-3: -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.

Detailed explanation-4: -Appendix. The appendix is perhaps the most widely known vestigial organ in the human body of today. If you’ve never seen one, the appendix is a small, pouch-like tube of tissue that juts off the large intestine where the small and large intestines connect.

Detailed explanation-5: -Examples of vestigial organs in humans usually include the appendix, the coccyx (tail bone), and the tonsils. Body hair, wisdom teeth, nipples on males, nictitating membrane of eye, tonsils are also the vestigial organs of humans.
