Answer:
Vestigial structure
Step-by-step explanation:
Homologous structures are physical structures such as organs or skeletal elements present in numerous species that come from a shared common ancestor. Analogous structures are bodily structures that resemble one another superficially and provide a similar function but have evolved separately and do not come from a shared common ancestor (such as the wings of an insect and bat). One vestigial structure present in humans is the appendix. This organ was once vital in the consumption and digestion of uncooked meat, but no longer serves a function.
