anonymous · Answer

A. The human tailbone

Note that a vestigal structure does not necessarily mean that it is useless, but a vestige from the past that is no longer needed or used for its original purpose.

It is a human tail bone.

Vestigal Structure is something that a species doesn't use as they did when their ancestors like our did, humans are believed to have a tailbone at one point, but today it has no use so it just goes inside ou.
