So you are trying to tell me, that you base the origin of all life on earth on some test on yeast (which the experiment is called an adaptation, not evolution) and enzymes?
I think in a way this is the amazing thing about science. Having a formal logical structure enables scientists to extrapolate from the mundane to the grandiose. So yes, tests like this
do bear on the question of the origin of all life on Earth. I think that's the reason science has been so successful. These days physicists are refining (testing) theories at various extremes, in what might seem to be extravagantly mundane ways! Do I really care about the dynamics of how heavy mesons, things that hardly even exist in nature, decay after pico-, femto-, or even yoctoseconds? Yes, because this is the level at which various new physical theories are expected to diverge from each other.
Well, that's what's amazing about science. But I think it's also very misunderstood, as people debating ID in schools seem to put too much confidence in science. Science provides very powerful methods for disproving theories, but is incapable of proving anything. Even Newton's "Laws" (still called that today) were falsified. It took about 350 years, but it happened. (They are still extremely valuable since they are an excelent approximation in most cases and a great deal of knowledge exists on how to apply Newton's laws -- Lagrangian dynamics, Hamilton's method, the principle of least action -- these are some of the powerful calculational techniques developed from Newton's laws. But don't forget that they are not actually true.) The scientist most needs to be able to distance themself from their own valued ideas and theories. Because they must be as unbiased as possible when they put their own favorite theory on the chopping block and have at it.
So I agree with Alex's original post here, that ID could be taught in a different subject in school, but should not be taught by science teachers. At best it can be classified as an "interpretation" of evolutionary theory. I feel that in many, even most situations, teaching ID in school at all would not benefit those who support it. Like it or not, kids learn a great deal at home. And if ID is really a fundamental part of a particular religion, then it can definitely be taught in the church.
At the same time, a good science teacher will place emphasis on the scientific process. It should be made clear that evolution, like any other theory, has not been "proven." It has been quite successful in many ways, and it even has a few challenges. I think there are still gaps in the archaeological record which could be viewed as new places to gather data and help test the theory. And modeling the predicted rate of evolution is a difficult work in progress.
Finally, while the scientific process can sound very straight-forward, it rarely is. Falsification requires reproduceable tests, because experimental techniques can be rightly criticized. Also forming predictions based on the theory is not always easy, and brings room for debate. I imagine that's particularly true of evolution.
