...no... but, given a particular nerual architecture, a "spaced-out" nervous 
system will tend to consistently lose competitions with a scaled down version 
of the same neural architecture, because the more-compact version will 
converge faster, and be more energy-efficient... cephalization has even more 
advantages because, besides shrinking interconnection lengths, it allows the 
head-localized sensory apparatus to orient relatively independently with 
respect to the body, and minimizes "fancy" through-the-joints conveying of 
information (hard to protect, and prone to injury... like one's "funny 
bone")... ken
People hate because they fear, and they fear because
they do not understand, and they do not understand 
because hating is less work than understanding.
