It's when someone tries to back off of a statement they've made or a position they've taken. If you ever watched a crawfish fleeing, it will make sense.

Fair enough. Sorry if I misunderstood.
Species primarily change generation to generation by the genetic processes Mendel discovered. This mix-match of genes is the culprit in ring speciation and animal husbandry and it does not necessitate mutations to achieve what we have observed it doing throughout human history. This mechanism can get you an incredible variety within the types such as canines or equines (walking Cali to Maine), but it is not going to get you from bacteria to man (walking Earth to Mars), without something else.
Y'all claim it is mutations, but have not shown, scientifically, that beneficial mutations can account for the development of any organ, metabolic system, or behavior, much less occur at a frequency required to account for all organs, limbs, systems, behaviors, etc. that exist.
I have read a great deal of the literature about the evidence of such things as the 'evolution' of feathers, eyes, legs, et al. and they all have one thing in common, the requirement to assume Naturalism, which I think is a faulty and discredited philosophy. They take some fossils, many time small fragments of a long dead animal, and spin a tale of how it lived, what its ancestors were, what it looked like, who its descendants are, etc. The language is saturate with 'probably', 'may have', 'could have', 'should have', etc. This is the language of speculation and hypothesis, not scientific evidence.
To sum it up:
1)Naturalism is a failed philosophy.
2)All the evidence for universal common descent is circumstantial and dependent on Naturalism's presuppositions.
3)Therefore, universal common descent is a failed hypothesis.
I don't need to spend all my time talking minutia of every naturalistic interpretation. I only need to demonstrate that Naturalism is false and that it has a negative impact on every area of human thought and discovery.
Ok, sorry. The image that popped into my mind as I read your post was of one of those goofy preschool shows explaining something scientific to a kid in a diaper with pudding smeared all over his face.
You make a good point here. I acknowledge that there are those who hold to a Methodological Naturalism for science but do not believe it represents reality.
In theory, I could almost accept Methodological Naturalism, but it runs straight into the same problem as the full blown philosophical variety. If Methodological Naturalism concerned itself with strictly scientific issues, it would be more benign. The problem is that it doesn't. If it did, we would not see such lockstep agreement on every level of this debate between the pure and the methodological when the discussion steps outside science and into philosophy, which it does most of the time.
Sure, a Methodological Naturalist may go to church and believe in Jesus, but at work, he is accepting the same presuppositions in the interpretations and theories as his colleague who doesn't drop his Naturalism when he leaves work, i.e. that there can be no supernatural explanation for anything in the universe.
If you accept a false philosophy only when doing science, it is not a virtue. At what point is any evidence of the Creator that you believe in admissible as evidence? How far will you go with Methodological Naturalism before it finally runs your theism under foot? Whenever it happens, you're just another nutty 'godidit' type to the true adherents of Naturalism.
Again, sorry if I misread you, and the Blue's Clues was just to illustrate how I perceived you talking to me like a kid that just soiled himself and had never heard the word science before. It was probably nothing like Blue's Clues. I was just grabbing for something of that genre.
I wasn't differentiating between pure Naturalism and Methodological Naturalism because, in science, there is no appreciable difference.
To hold to theism, Christianity specifically, and Methodological Naturalism is an illogical dichotomy. Naturalism and Christianity are mutually exclusive. I am not saying that those who hold your position aren't Christians, please understand. I just think you hold to an irrational position.
