All good and well. But remember that ID proponents like to tout the fact that something like the famous extra flagellar motor cannot "evolve". They reckon that in it's constituent parts, it would be useless. The counter-argument is, much like in this case, that all the constituent parts may already be in the cell, being used in a different way, and that only a small change would be needed to make it start "functioning" (perhaps not as effeciently as what we have today, but even a rudimentary device would be sufficient to allow refinement to continue).

This is what I like about this finding... a small change that augments what the cell can already do, leads to a completely new way for these bacteria to "eat", and vastly out-perform their counterparts.

Biologically speaking it may not be stunning, but ID proponents will nonetheless deny that this is of any value (much like other biologically non-stunning things that they deny). Perhaps this _could_ address the problem they have with not "seeing evolution in progress". Hopefully this will lead to more changes in the bacteria that could provide us with a number of transitory forms. I'd love to see the hoops they jump through to disprove that.

However, to me, the ultimate truth bible swinging fundementalists are denying is this: Religious institutions have been touting the "truth" in the bible over science for many centuries. Every time, every single time, science has prevailed and proved scriptures (and the clergy) incorrect. To think that the present situation is any different than any of the times before that, to me, is utter folly. The technology may be more advanced, the concepts may not be fully proven yet, but science has a far better track record on these things than scripture.

If all 12 samples showed the same evolution path it would have been handy for the ID or “Final Causation” advocates; but only one sample went this way, even with several iterations of turning back time and running evolution over again. I suppose that's not enough to prove the opposite though. What a Kalamity…
