Why complex form requires an Intelligent Designer

Isn't KBC's whole argument just the same old misunderstanding of the nature of evolution as gradual change Vs the wholesale change argument put forward by proponents of ID everywhere? Isn't the OP effectively jumbo jets in junk yards again with jazzed up and overly complicated details?KBC seems to be saying that a femur (in this case) could spontaneously become any one of an infinite number of bizzarrely shaped bones in one single jump between successive generations. He concludes that because there are only an impossibly small number of conceivable shapes that could be deemed useful that ID must be true!!!Nobody is claiming Evolution works like this. A single mutation may result in a slight change in size, density, shape or any other physical attribute of the femur in question. That slight change may give a slight advantage to the survival and mating prospects of that individual organism which they then pass onto their offspring. And so we go on.Nobody is claiming that randomly shaped bone structures appearing in randomly located bodily positions is any sort of method of evolution except KBC. The fact he then asserts that evolution cannot realistically take place by this method is trivially obvious to all!!!!!!Either I have got the wrong end of the stick regards the OP or I don't get why the discussion is getting so bogged down in details when the whole premise of the OP is just the usual ID silliness seen time and time again.

Fair enough. You have more patience than I do obviously.To KBC I would just say - Nobody is claiming that single random major changes to particular bones (or anything else for that matter) are the mechanism by which evolution occurs. Your whole argument aginst random mutation rests on these sorts of dramatic physiological changes. Therefore all you have "demonstrated" (I use the term loosely) is that an obviously false mechanism of biological change that we would all agree is impossible is indeed impossible. Nobody is claiming otherwise. Congratulations for that.
Does your essay have anything to say regards small graduated changes to existing physiological structures? If not it has nothing to say about evolution by NS.

Actually almost all shapes are precluded. Any shape (or other physical characteristic) of the body part affected by mutation must by definition be based on the original body part of the parent.
