A major evolutionary step was the process of cephalization (getting a head), with chordates having a single brain rather than a series of ganglia. What advantages does a brain confer to an animal that is not possible with ganglia?
What will be an ideal response?
This answer should discuss the survival advantage of a single brain over a series of ganglia. The one brain allows integration of information from anywhere on the body and allows for a response that involves the entire body, so escape from a threat can be more effective.
