Why would a vestigial structure once it has been reduced to a certain size not disappear altogether?
With time, if an organ or structure is no longer needed, natural selection may reduce the size of the organ until it completely disappears from the species or is very reduced in size. It is suggested that some vestigial organs may remain in a reduced state because they have a minor function within the body.

While the appendix and coccyx may not serve a critical function in humans, they are believed to be remnants from our evolutionary past. The appendix may have played a role in digesting certain types of food in our ancestors, while the coccyx is a vestigial structure from when our ancestors had tails. While they may not be necessary in modern humans, they do not necessarily harm us either.
