Good questions all. But is it a complete list? One problem I've had with IC is that often when we look at a system we find that many of the parts first evolved to serve some other function, one that is definitely not IC, and were then co-opted for that later function.
The world we live in is marvelously complex. And there are multiple solutions to nearly every function you can imagine. Plants see with no eyes. They eat with no mouths. They move without legs and fly without wings. They colonize without cities and attack others without armies.
The big question for me in all of the ID/IC questions is "Why ask?" If we can simply look at the system and first understand it, can we then just look beyond to find similarities either in function or detail in other systems that may or may not serve the same function? If we find the pieces parts all ready available, or if we find the function being acomplished with other pieces parts, can we eliminate both ID and IC.
