You are simply a pathological liar!. Irreducible Complexity was coined by Behe and is the central tenet of Intelligent Design Creationism. It is the opposite of Evolutionary Theory.
Oh, I know Behe coined the phrase,
but the principle is actually part of Darwin's theory. It is not the 'opposite' of anything, because Evolution deals with species evolving, not origin. Darwin made a very detailed analytical standard for natural selection, because he realized it couldn't simply be used willy-nilly to explain anything and everything.
Here is what Darwin said regarding his theory and the human eye: “to suppose that the eye ... could have been formed by natural selection, seems, I freely confess, absurd in the highest possible degree”. He goes on to explain that if gradual evolution of the eye could be shown to be possible, “the difficulty of believing that a perfect and complex eye could be formed by natural selection ... can hardly be considered real”. He then proceeded to roughly map out a likely course for evolution using examples of gradually more complex eyes of various species.
Now it is on this prerequisite of natural selection, Behe makes his argument for irreducible complexity. The powers of natural selection are not predictive, they can't presume to know that a photoreceptor spot is going to need a lens, an iris and pupil, and then form it. IF evolution is this amazing, it is more of a miracle than God. The simple photoreceptor cells, which Darwin very well knew about, were thought for a long time, to be a predecessor to the modern eye, but as we've learned more about the optic nerve and chemical reactions, the more we understand the two systems are completely different. Humans do not utilize the optic nerve in the same way as something with a photoreceptor cell. The operation of the optic nerve is entirely different, but Darwin didn't know this.
So the evolution of the eye has not been shown, as Darwin previously thought. The eye is irreducibly complex, meaning; if any one component of the eye is not present, the system doesn't work. If evolution is responsible, it had to 'intelligently' compile a checklist of parts needed, and construct what we know to be an eye. There is no "simpler stage" the eye could have had, and still function at all. What we once thought to be links to primitive photovoltaic spots, turned out to be false leads, the systems are completely different and operate on a completely different principle.
Behe's argument is not to be carried as far as you rhetorically like to carry it. Natural selection can indeed produce a more complex or robust system over time, but it has to work within the confines of what is natural and within bounds of nature. It can't predict that various components will eventually be needed and start building those, so they are complete when everything else is in place. That's just not how natural selection works. If you believe that natural selection has the ability to be predictive like this, you believe in "intelligent" design.
