Err..., you know something about feedback! Yes, in classical feedback systems, the loop phase better be < 180 degrees if the gain > 1.0. In Natural Selection, the feedback function is not a classic linear function, so no, you are not passing the output signal through a linear transfer function and subtracting from the input signal. But the selection is still viewed as a feedback function. In the same way, the forward "plant" function is also not a linear transfer function, instead, it is the non-linear gene replication & modifications mentioned before and reproduction. I agree, that this can clearly create complexity. Genetic Algorithms have shown this quite well. But understanding how this works is not the same as having a neat mathematical definition of complexity along with a proof showing that this method produces complexity. If we had such a proof, the ID nonsense would be stopped dead in its tracks. Right now, they produce all sorts of nonsense because we lack such a proof.
