The body does not need to expend as much effort to process and use cooked food. The appendix is a vestigial organ, originating from the cecum, a structure used to process foods. Many animals (like horses) still have a functioning cecum. As the human appendix cannot help digest food in ...
of a body part or organ remaining in a form that is small or imperfectly developed and not able to function : being or having the form of a vestige (see vestige sense 2) Kiwis lack an external tail, and their vestigial wings are entirely hidden beneath a curious plumage—shaggy, more li...

(the boas). in humans, the appendix is a good example of a vestigial organ. this non-functioning organ eventually degenerates, shrinking in size and disappearing ultimately. examining vestigiality should be governed by drawing similarities with their counterparts with respect to their homologous ...
