Why do you think a person can have their appendix and wisdom teeth removed and still live a normal fully functioning healthy life? It is a vestigial structure so it doesn't have a function anymore. It is a homologous structure, so we have more than one.

The appendix and wisdom teeth are considered vestigial structures, meaning they no longer serve a significant function in the human body. The appendix is a small pouch attached to the large intestine, and it is believed to have once played a role in digestion. However, in modern humans, it does not have a clear function and can even cause health issues such as appendicitis. Wisdom teeth, also known as third molars, were once useful for grinding food in our ancestors' diets. However, as human diets and jaw structures have evolved, wisdom teeth often become impacted or infected, leading to the recommendation of their removal.<br /><br />The removal of these structures does not typically affect a person's overall health or functioning. The body can continue to operate normally without them. It is important to note that while the appendix and wisdom teeth are considered vestigial, they are not entirely useless. They can still play a minor role in certain situations, such as the appendix providing a small amount of immune support. However, their removal is often recommended when they cause problems or complications.
