They are not. They actually form a ring around the back of the mouth to help to protect the body from food that may be infected.
(Sorry, people never ate grass only).
Tailbones, tonsils, appendix,
Some examples of vestigial structures in humans include the appendix, coccyx (tailbone), and ear muscles that are no longer used for movement. These structures are remnants of ancestral features that have lost their original function over time through evolution.
The appendix, tonsils, wisdom teeth, tailbone (coccyx), plica semilunaris, and arrector pili muscles are commonly cited as vestigial organs in humans. These organs are remnants of structures that were functional in our evolutionary ancestors but have reduced or lost their original function in modern humans.

Vestigial StructureA vestigial structure is a structure that appears to no longer have a use in the body.
Tonsils, palatine tonsils and Waldeyer's ring. Tonsils are part of the lymphatic (Immune System)
Vestigial - [veh-stij-ee-uhl]
The opposite of vestigial organs would be functionalorgans.
No, the claws of a lion are not vestigial.
They don't. Useless structures that are called "vestigial." This means that they used to be some use to us, but now aren't. They haven't evolved out of the human species because we have not been under selective pressure.
Vestigial means a very small remnant of something once larger. The appendix is a vestigial organ. Some people are born with vestigial tails.
