Expert Answer:

Vestigial organ is an organ that was once useful in an animal’s evolutionary past, but now has no apparent nor predictable function. e.g. rudiments of hind limbs in snakes, wings on many flightless birds.
The appendix has lost its original function or has evolved again to take a new function which is why it is called a vestigeal organ. It was found in the cecum in the early ancestor of humans.
