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.

Humans: the appendix, wisdom teeth, and ear muscles are examples of vestigial structures. Whales: hip bones and hind limb remnants are vestigial structures in whales. Pythons: pelvic spurs, remnants of hind limbs, are vestigial structures in pythons.

Those organs are called vestigial organs. They are remnants of functional structures that were more developed in ancestral species but have decreased in size or usefulness in the current organism.
Vestigial StructureA vestigial structure is a structure that appears to no longer have a use in the body.
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.

Vestigial structure is used in application to structures that are determined genetically but do not have the ancestral function.
Tailbones, tonsils, appendix,
yeah
Yes you just did
vestigial structures.
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.
