Talk:Cephalization

From Wikipedia, the free encyclopedia

"Cephalization is advantageous in that organisms with greater cephalization can analyze a new and potentially hazardous environment without moving their entire bodies into it."

This explains why it is advantageous to have a head (i.e., an extension with sensory organs located on it), but not a brain in the head. In fact, the explanation here provided has nothing to do whatsoever with why cephalization is evolutionarily advantageous. The best explanation concerns the costs of sensory-motor neuronal fibers that extend to the anterior and posterior regions. See "Component Placement Optimization in the Brain" (1994) for more.

For now, I suggest you high school kids stop writing whatever it is you feel like writing. Cite your sources. And stop writing whatever it is you feel like writing.
