In multicellular organisms(specifically of the Kingdom Anamalia), how did random mutations create input systems(senses) and difference engines(brains, or their primitive equivalent)? If the mutated individual is to benifit from a sensory mutation such that it was more successful at producing offspring, would it not require some sort of difference engine to interpret and act on the incoming messages? Inversely, how would an individual benifet from a mutation that produced a crude semblence of data processing(the odds of such an occurance are quite remote, I might add), if it did not posess any sort of sensory system, including nerve conections?
The only way these would benifet an organsim would be for both "brain" and senses to apear simultaneously in not only the same species, but the same individual. How is such a statistically improbable event possible?
