Question

Quizplus · Accepted Answer

The presence of auricular muscles in humans is likely due to their evolutionary history and inheritance from mammalian ancestors. While they may not serve a direct purpose in humans, they are not entirely vestigial as they can still be used to make minor movements of the ear. There is no evidence to suggest that they have any role in swallowing or tongue retraction, and while some people can wiggle their ears, this is not a trait that would confer significant reproductive advantage.
