Vestigial structures are anatomical features or behaviors that no longer seem to have a purpose in the current form of an organism of a given species. They are typically formed through the process of evolution, where these structures or behaviors were necessary in ancestors but are no longer needed or used in the current species.

For example, the human appendix is often cited as a vestigial structure. It is a small pouch attached to the large intestine where it joins the small intestine and does not play a significant role in human digestion. In ancestral species, it is believed to have been much larger and to have helped digest a diet that was much richer in plant matter. As human diets changed, the appendix became much smaller and its original function was lost.
