Vestigial structures Notes:
A "vestigial structure" or "vestigial organ" is an anatomical feature or behavior that no longer seems to have a purpose in the current form of an organism of the given species. Often, these vestigial structures were organs that performed some important function in the organism at one point in the past. A good example of this is the appendix in humans which apparently seems to serve no purpose.
