Natural selection is just a term for a class of feedback systems. The selection process is analogous to a delayed feedback system, but there are some significant differences. In a classic feedback design stability is achieved by subtracting mistakes in the fidelity. This only really works if the mistake in fidelity is still occurring .. that is .. too much delay and the correction is applied to a new input that is not exhibiting the same mistake. In natural selection corrections are not applied. "Mistakes" are eliminated, they are not applied to existing "signals". The original signal (or some continuation of it) is never corrected. Complexity in evolution arises from this distinction. The copies of organisms contain a lot of variation, some mistakes and some which are just differences. The mistakes are on average eliminated, and the differences must compete for limited resources. Some of these differences are more complex. There is a greater chance that an organism which has everything that competing organisms have plus more will out-compete those that have almost everything except are missing some element that was successful in the past. On the average the trend will favor the more complex. TP
