Through evolutionary changes, an organism might retain a lasting organ or anatomical feature that is no longer useful. The appendix is a vestigial organ in humans- it serves no purpose but may have been useful before a major change in the digestive system.

∙ 13y agoThey seem to have lost much of their immune system function, though the argument over their vestigial status is not settled. Vestigial structures are structures that have lost their original function, but can be still useful. Creationists mistakenly think that vestigial means ' useless ', which it does not. The tonsils seemed to be organs of first line defense against ingested pathogens which now seem to be somewhat dangerous is some people to keep past a early developmental stage.

How do vestigial structures work?
They don't, vestigial structures are biological structures with no known function that evolved from structures in distant ancestors that used to have a function that is no longer needed.

How do vestigial structures provide evidence that we evolved from organisms that existed in the past?
Vestigial structures are anatomical features that have lost their original function in an organism but are still present. These structures often have similarities to functional structures in related organisms, suggesting a shared evolutionary history. By studying these vestigial structures, scientists can infer how organisms have changed over time through the process of evolution.
