The term vestigial comes from the Latin word vestigium, which means track or footprint. Explain how this relates to the meaning of vestigal structures

A track or footprint is something that is left behind by an organism that was there before. A vestigial structure is one that had a function in a previous organism but does not have a function in the organism you’re referring to. The structure has been left behind by another organism.
