Interesting that I keep seeing these same arguments crop up across multiple websites. On the side of "exposing" Expelled is a decent site
WWW Link.
I do have a degree in molecular biology as well an MD, and took courses in evolution, as well as doing years of basic science lab work. Like any other scientific endeavor, "evolution" is a vastly more subspecialized and complex field of study than most people realize. In fact, the more educated people get in an area, the more likely they are to recognize how much they still do not know. Try not to equate this with "they don't know anything."
Go looking in real scientific literature, and you will find unimaginably huge reams of evidence supporting evolution, though I'd be surprised if you could really understand even 1% of this. Don't take this as condescention, I'm in the same boat. Nor would I expect them to pass my Internal Medicine board exam, or me to score well on an exam in astrophysics. Science is based on:
1. Generating a testable hypothesis.
2. Testing it (gathering data).
3. PEER REVIEW (having others with similar background look at your assertions/test protocols to see if they hold water).
4. Reproducibility (if they did it, do I get the same results repeating the work)
5. Revising a theory based on new data.
Look where the scientific method has gotten us in the last couple of hundred years compared to all prior human history in terms of our capabilities. Now if only human nature could catch up.
I think from my standpoint, the important thing for our educational system is to focus on teaching critical thinking, and keep science and philosophy and/or religion in their proper context. For my part, ID has by comparison not generated even a grain of sand of "evidence" to put up against the beach of sand grains generated by real scientific evidence.
On a side note, an interesting "skeptical" site for medicine is quackwatch.org, its got some thought provoking or "eye opening" articles.
