Question #1. If bilateral symmetry were to evolve among cnidarians, in which group or groups would you expect it to
occur? Why? From reading the book, I will determine that a bilateral symmetry would evolve in a group of symmetrical worms. From the understanding of the book a biliteral symmetry is the arrangement of body parts in such a way that there is only one way to cut the body and get two identical halves. Therefore, a good example for a cnidarian group may be a flatworm. Flatworms are bilaterally symmetrical invertebrates typically flattened in appearance. They have true organs and organ systems, including a central nervous system. In addition, flatworms are symmetrical on both sides when cut in half.

This answer is wrong it will evolve in jellyfishes, flat worms are not in the cnidarians group
