>I think the evolutionary argument, as usually stated, rests of a big mistake about what nervous systems, immune systems, genetic regulatory nets, etc., evolve to do. This is not transmit information from one place to another, or be "flexible" in some abstract sense, but cause actions which enhance the fitness of the organism they happen to be in. Biological systems don't evolve to do anything - they randomly mutate and are selected by a stochastic process that loosely correlates with Darwinian fitness. Chaos is the default state of all matter; most systems operate on the edge of chaos not because there is something desirable about that state, but because any amount of order emerging from chaos is highly improbable.
