a Vestigial organ is an organ of the body that doesn't seem to serve any useful purpose, but similar organs in other animals do. It is supposed that our early ancestors had use for the organ but now, as we have evolved, the organ has become redundant. As we continue to evolve, we may lose it altogether.
If the theory of evolution is correct, then many animals could be found with vestigial organs. For many years, it was thought that the appendix was vestigial and served no purpose. It was believed to be a vestigial form of the caecum found in many herbivores. Indeed, it probably is. However, we now know that it is wrong to believe the human appendix has no function. It is very important in developing the immune system in foetus and young child and may have a role in recycling haemoglobin from dead red blood cells. But it certainly has lost its role in digestion.
It is interesting that organs are sometimes described as vestigial, simply because the scientists haven't yet worked out their real use.
The appendix is a vestigial organ.

Vestigial means a very small remnant of something once larger. The appendix is a vestigial organ. Some people are born with vestigial tails.
Vestigial refers to something that is no longer needed or useful. Our appendixes are an example of a vestigial organ-they serve no biological purpose
A vestigial is an organ that serves no useful function in an organism.
I believe this sort of structure is called a vestigial structure (a left over remnant). The appendix is another vestigial organ.
