Hi David,
Before I start, are you the same David Fitch who studies Caenorhabditis nematodes? If so I used a reference of yours (as background) when doing my MS work on hermaphroditism and sex allocation in caridean shrimps.
Anyway, I am intriqued by your statement:
Has no one in this forum actually read Darwin's "Origin"? I'm surprised that people think ID makes no predictions about patterns of variation.
Are these two points or one? I have read Origin (although it has been some years since I have read it cover to cover) and have been trying to recall where Darwin discusses predictions from NS vs ID specifically. When discussing structures such as the eye (the archetype of ID design theory at the time) I think he wasn't discussing it in the sense of "Here is the eye, here are two hypotheses of origins, which holds up to predictions?". He sounds to me like he looking at complex structures, relationships, adaptations and the like as NOT supporting ID under scrutiny. I hope I can make my point in a clear manner (I am under the gun here, need to go in 15 minutes!).
Intelligent design theory (as per Paley) doesn't make any predictions as to how a structure should look. The only 'prediction' inherent in design theory is that it is impossible to arrive at stepwise. "Structure X is irreducible in complexity and has no viable intermediate steps; therefore it can only exist as the product of intelligent design" The prediction is that ID is the ONLY mecahnism that can produce it. Not what the structure looks like. So Darwin states that structure X can easily be derived from slight changes in structure W which comes from V... and so on. He is nowhere (that I recall) looking at the complex structure of the eye and analyzing which theory best explains it. He says that the eye would be a problem IF no steps could be found, and btw here they are.
I apologize if you intended those statements to be unrelated ("No one here has read Darwin" AND "People think that ID makes no predictions" as opposed to "No one here has read Darwin's discussion of how ID makes predictions"
