These are "intuitive" attempts at disproving evolution. The problem is that intuition isn't acceptable as a standard of proof in science. That's why their ID arguments aren't properly even a scientific topic.
Actually, I'd say you've got to give them a little more credit than this. (Not a whole lot more, but a
little bit more).
They didn't just claim 'This thing couldn't have evolved', and then leave it at that. They made a very specific claim. They claimed 'Irreducable Complexity' to be a very specific, objective catagorisation, that could be described thus:
'If any single part is removed from the 'system', then the system ceases to function'.
That's not the exact wording (and the exact wording is quite important actually - I'll take some time later and look the exact wording up, but anyway...) If this idea was in fact correct, then it would very much challenge our notions of evolution, because evolution relies on small, incremental changes.
The trouble isn't with the framing of the question. If an organism which is proposed to exist due to evolutionary process COULD be demonstrated to be irreducibly complex, then it would be
devastating to the ToE. Even Darwin said so.
The problem isn't with the challenge. The problem - for ID-ers - is with the
reality of the situation. ID-ers - at the Dover trial - constantly went on about the bacterial flagellum as THE example of an 'Irreducibly complex' organism. They bought it up time and time again.
...and yet Ken Miller and co. simply demonstrated that the bacterial flagellum was NOT irreducibly complex. There can be no argument about it. Take away one part, or in fact as many parts as you like - take away whole chunks of it - and it
still functions. It does 'different things', but it still functions.
The same idea is destroyed in relation to blood clotting - with REAL examples from the natural world.
All that is somewhere around the middle of the presentation I linked to. (Can't remember where exactly...)
