The legend on the bottom left reflects three basic conditions that describe the character that pertains to body covering (or integument). The conditions that pertain to the specific taxa at the top of the tree are shown by the numbers.

These are structures that have been reduced to the point that they are virtually useless. Ear muscles and the tail bones are examples of vestigial structures in our own species. Explain how vestigial structures provide clues about a species' evolutionary past. Illustrate your argument with vestigial structures found in humans or other real species.
