Quizplus · Accepted Answer

The tailbone, also known as the coccyx, is a vestigial feature in humans. This means it is a structure that has lost its original function through evolution. In humans, the tailbone once served as an attachment site for muscles that controlled the movement of a tail, but as we evolved to walk upright, the tail became unnecessary and the tailbone became smaller and less functional.
