A vestigial structure is part of an organism's anatomy that functioned in an ancestral species, but which is no longer present in the same size and does not serve the same purpose. In some instances, it is completely redundant.
Examples of vestigial structures are the tailbone of a koala and the leg bone in a baleen whale.
The appendix in a human being is often thought to be a vestigial structure, but recent research indicates the appendix may still perform a very useful purpose in the immune system.
