disadvantages of cephalization

Cephalization - Wikipedia Because there are several hundred types of cells that make up the tissues. In his system, a centered dot acted as a comma; a low dot as a colon; and a high dot indicated a very long pause. Arthropod body segments are sometimes distinct, sometimes indistinct, and sometimes fused as groups to form body regions. The evolution of bilateral symmetry that allowed for the formation of anterior and posterior (head and tail) ends promoted a phenomenon called cephalization, which refers to the collection of an organized nervous system at the animal's anterior end. By such regeneration whole organisms may dramatically replace substantial portions of themselves when they have been cut in two, or may grow organs or appendages that have been lost.
