How did the Venus' flytrap avoid the argument that IC can't evolve? In two ways. First, rather than gaining a part, it lost a part - the glue that the sundews use. Even more interestingly, the trap was able to evolve because the parts evolved. The trap started out as a Drosera-like leaf, and the parts of the leaf were progressively changed. This makes a striking contrast with the mousetrap which Behe has repeatedly presented to illustrate why IC cannot evolve. As a manufactured item the mousetrap neatly illustrates his definition, but with its static parts it cannot model evolution. With evolving parts, nature can create a snap-trap after all. The mechanical and manufacturing analogies so influential in Behe's thinking miss the flexibility of living things.
Maybe I'm missing something here. This isn't terribly convincing.
You are forgetting that you presented the venus fly trap as an example of IC. Disco presented a mechanism that shows how such an adaptation could evolve with all of its concomitant parts playing useful roles, that would be subject to positive selection in their own right, prior to the evolution of a complete 'venus fly trap'.
You can't dismiss it because on the basis that it debunks your IC argument.

Actually not just irreducibly complex ones, any demonstrable genetic 'innovation' would do. Name some.[/url].
Is your argument that because we haven't observed feathers growing on fish or trunks sprouting from cats in the last thousand years that the evidence that we do have from the previous 4 billion years prior to that is somehow irrelevant?
To me the fact that the fossil record shows more basic organisms in the lowest stratum and increasing diversity and complexity appearing chronologically in younger stratum is a pretty good clue to the history of life on Earth.
To the above yes, I would like to see that, either in fossil form or living. Do you know of one?
Evolutionary theory does not predict such examples, so why would they be captured in the fossil record?
The fossil record without assuming things like long ages has this testimony:
When a major group of organisms arises and first appears in the record, it seems to come fully equipped with a suite of new characters not seen in related, putatively ancestral groups. These radical changes in morphology and function appear to arise very quickly K. S. Thomson, Morphogenesis and Evolution, Oxford, Oxford University Press, 1988, p. 98
also
The history of most fossil species include two features particularly inconsistent with gradualism: 1) Stasis - most species exhibit no directional change during their tenure on earth. They appear in the fossil record looking much the same as when they disappear; morphological change is usually limited and directionless; 2) Sudden appearance - in any local area, a species does not arise gradually by the steady transformation of its ancestors; it appears all at once and 'fully formed'. S.J. Gould, "Evolution's Erratic Pace", Natural History, vol. 86, May 1977
You are quoting evolutionary theory here. The observations that led to Gould's punctuated equilibrium. What need to read up on is current evo-devo theories and how minor genetic changes that affect development can be translated in the large morphological changes that we observe in the fossil record. You also need to grasp that individual organisms don't evolve....populations do. Evolution is caused by a change in gene frequencies in
populations so this can lead to subtle changes between species or large morphological changes that are selected for some advantage in any give ecological niche.
Your choice of quotes do not support your argument, on the contrary they describe exactly what the modern synthesis of evolutionary theory, that encompasses the processes of natural selection, genetic drift, molecular genetics/biology and their impact via punctuated equilbrium and evo-devo (amongst others), predicts.
What these quotes actually describe is some of the controversial areas within evolutionary biology....ie. the relative importance of the different evolutionary forces that drive change.....there is no debate on the occurrence of evolution by common descent amongst biologists.

ICR and other sites I use are simply people who are likeminded with myself. They are scientists who are reviewing and critisising evolutionary ideas. They quote the work of others and resynthesise or do original research. No different to what 'talkorigins' or the 'Panda's thumb (now that's a title that shows just a hint of bias)' do.
By 'like-minded' do you mean that they are trying to prove foregone conclusions. Just to remind you, that is explicitly contrary to the scientific process. Have a look at what the evidence shows. You add God to the equation before you assess the evidence, thus tainting your conclusions. If the evidence suggested a divine creator I, and the scientific community as a whole, would agree with you. But the fact is, the evidence does no such thing. What is this original 'creation' research?
The difference between these websites is that the talkorigins and the Panda's thumb (an homage to the late Stephen Jay Gould, a great mind in evolutionary biology who used observation and evidence to formulate theories that are important in the field) provide answers that are based on physical evidence, whereas the ICS and other similar websites try to skew the evidence to fit a preconceived notion...the existence of an omnipotent creator. Their findings are easily debunked and have been done countless times before.
As for the rest of what you said, why didn't God give us wings to fly, a nose like a dog's, the brain of Einstein and eyes like an
octopus (actually there is a reason)? Sorry, not sure, but it doesn't help your cause.
Um, the reason that god didn't do this is that he doesn't exist. Like you just said 'why didn't God give us.....'. if he existed he could have, but we have to rely on the mechanisms of evolution to explain our morphological, physical and mental traits. It seems to me quite obvious that this theory provides a more accurate prediction of the observations. In this light, I don't understand your final sentence.
I would still like you to explain the common insertion sites of viral sequences in hominid genomes. Just one example of very clear evidence of common ancestry.
