structures
analogous structures are different to another animal's structure, but serves the same function. The two animals had different ancestors, but similarly evolved.
homologous structures are similar to other animal structures, but have different purposes, the two animals must have had a common ancestor, but evolved differently
vestigial structures are ones without purpose. An animal's ancestor might have needed a tail, but the animal today does not. So the animal today has a tailbone, but no tail.
