Hi RAZD,

IC systems have been explained in evolutionary step for every model that has been proposed. More than that, one has been observed to evolve, thus invalidating the concept entirely.
Out of curiousity, which IC has been observed to evolve?
But my bigger question regards the IC systems being explained in evolutionary steps.
What I've read so far has been as follows:
IDers: Organism {O
z} has a structure or process {SOP
z} that is IC.
Evos: {O
a} has a simpler but related {SOP
a}. I can imagine this small change to {SOP
a} giving us {SOP
b}...and so forth until we reach {SOP
z}. Ta-da! It isn't IC after all.
But, for any of the proposed ICs and proposed evolutionary steps going from {SOP
a} to {SOP
z}, has a step-by-step been worked out for which DNA mutations would have to occur and the order in which they would have to occur to go from {SOP
a} to {SOP
z} -- forgetting the difficulty of whether an evolutionary line can even be thought to exist from {O
a} to {O
z} -- and forgetting the difficulty of where and how did the DNA/RNA structures and processes come from in the first place.
I have never seen the step-by-steps treated in a molecular way, but always wondered whether such models existed.
