Like clams, the brachiopod lives in a shell consisting of two hinged valves, but ...Radial Symmetry. Another trait that evolved early on was symmetry. To understand symmetry, you need to see an animal that lacks symmetry. A sponge, like the one in Figure below, lacks symmetry. This means it cannot be divided into two identical halves.
