So basically you're saying that evolution follows the idea of "a million chimps in a room will eventually write Shakespeare"? That its a matter of the number of times a new structure appears in each generation, rather than the quality of the structure itself? I agree with the idea of randomness being the source of creation. Being an artist there often seems to be no correlation with my ideas and the act of actually thinking them into being, they just sort of aggregate into a whole concept. In fact more often then not a bad idea usually occurs when i force myself to design it. Maybe theres a similar process going on with evolution, there is no purpose to the events that occur but chaos can gain an apparent rhythm that gives rise to function.
