Question

Wisdom teeth are the third and final set of human molars that come in during the late teens or early twenties. In some cases, these teeth come in without problems, but they often have to be removed due to misalignment in the jaw, as shown below. Removal of the teeth does not cause any long-term complications in regard to eating. Which type of anatomic structure are wisdom teeth?
vestigial
homologous
analogous
heterologous

Answer 1

Vestigial is the correct answer I believe.

Answer 2

The correct answer is vestigial.

A vestigial composition is an anatomical characteristic, which no longer appears to exhibit an objective in the present form of an organism of the given species. Usually, these vestigial compositions were organs, which had done some essential activity in the organism at one time in the past.

The examples of human vestigiality are plentiful, involving the anatomical compositions like wisdom teeth, human tailbone, and inside corner of the eye.
