Answer 2

Vestigial organs are the structures which have no apparent function in a particular organism perhaps once they did. They appear to be a residual part of a past ancestor. For example, as in snakes, they have pelvic bones although they do not have legs because they are descendants of reptiles which possess legs.

Human vermiform appendix is another example of vestigial organs and this is the most cited example to support human evolution. These unused structures present in an organism are called vestigial structures.
