|ID does NOT say that evolution cannot produce IC. That you would say such a thing exposes your ID ignorance. Thanks, although it has been very obvious that you don’t understand the basics.|
If you ask 3 top-tier IDers a basic question like "Can evolution produce IC?", you'll get 4 different answers. Joe's accusation that Pixie is ignorant of ID assumes that there's a single ID "theory" to be ignorant of. Sorry, Joe, the tent's way too big for that.
That's because there are multiple definitions of IC (Irreducible Complexity). Behe has defined IC as "composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning". But IC can be produced by step-by-step evolutionary processes, such as by removal of components, by cooption, or by duplication and specialization.
A simplistic example is a function A which is duplicated into A1 and A2. It is possible for each component to evolve to optimize aspects of the overall function while losing the ability to perform the entire original function in isolation. Complex and irreducible cascades can be created in this fashion.
