Which is not a vestigial organ in man :Vestigial organs are reduced, functionless organs that were useful in ancestors.
In humans, the wisdom teeth (third molars), coccyx (tail bone), segmental abdominal muscles, nictitating membrane, vermiform appendix and ear muscles are vestigial.
Nails are functional (they protect the tips of fingers and toes and help in picking things up), so they are not vestigial.
So nails are not a vestigial organ.
