Bilateral symmetry is a body  plan in which the right and left halves look the same.

Cephalization  is an anterior concentration of sensory structures and nerves.

A coelom is a fluid-filled space between the body wall and the gut.

The function of genes is to carry the instructions for making a protein.

Phylogenic relationships provide very strong evidence for evolution, because they reflect relationships indicated by the fossil record.
