Here is a simple example: A new horse fossil is discovered and evolutionists decide where it fits best amongst the already known fossils. It may not fit perfectly, and the evolutionists may be unsure about which twig in the evolutionary bush is right for this new fossil (or if perhaps a new twig should be hypothesized). But they believe evolution is true and so the fossil must fit somewhere. They announce to the world that horse evolution is now better understood and apologists then use the finding as an example of powerful evidence for evolution. After all, the evolution of the horse has been revealed. But of course the fossil revealed no such evolutionary step--it was interpreted as an evolutionary step. Unfortunately this sophistry is common.Never mind that even young-earth creationists who have bothered to actually learn a little about the evidence -- like Kurt Wise -- admit that the fossil record of horses, and the fossil record of numerous other groups, support an evolutionary interpretation. Never mind that Hunter, for his part, spends his time making up excuses rather than explanations for data. Never mind that Hunter's only "model" is just "God does things however he pleases, and it is not for us to question." And he has the chutzpah to endlessly accuse scientists of bringing religion into science? Now that's sophistry.
Hunter vs. Hunt on Turf-13
As a last treat for the 150th anniversary of the Origin, have a look at young-earth creationist creationist Cornelius Hunter [Update: Hunter has stated he is not a young-earth creationist on his blog, so I guess he's not, although that position directly follows from his stated theology/philosophy], author of the "Darwin's God" book and blog. Hunter's basic argument against virtually any common pro-evolution argument is, basically, "But you evolutionists are claiming that God wouldn't have done it this way! You're making an unscientific theological argument!"
(Never mind that when science writers have said things like "this looks like bad design", they are simply using the design model that creationists themselves put forward -- basically, that God is like a human designer, but way better. And never mind that the more sophisticated critiques of creationism -- like Darwin's -- have noted that if you disallow the standard creationist assumptions, and just say God's purposes are mysterious, then you've got nothing at all to test against empirical data.)
Anyway, as with many creationists, Hunter thinks his ridiculous little trope is actually a silver bullet that can be used to effortlessly kill any evolutionary evidence, thus saving his tender innocent brain the trauma of actually having to come up with a better explanation than the evolutionary one. The best example of this of late is Hunter's reaction to T-urf13. In these posts awhile back, PTer Art Hunt explained that T-urf13 is an example of not just a new gene evolving from noncoding DNA -- but it appears to be an example of an oligomeric protein complex, with the function of being a regulated ion channel, evolving from noncoding DNA. This natural origin of "new information" AND "new protein-protein binding sites" is just the kind of thing that antievolutionists -- most recently ID leader Stephen Meyer in his Signature in the Cell claim can never, ever, ever happen, because the improbabilities are so huge, and because "intelligence" is the only possible explanation for new information.
Well, how does Hunter react to this empirical evidence on the origin of a new gene? He simply ignores the overwhelming sequence evidence right in front of him, and instead claims, based on typical creationist "it must have come together all at once from completely random sequence" assumptions, that the natural origin of T-urf13 is too improbable to be believed. On the strength of this careful, rigorous, half-a-sentence of statistical analysis, Hunter deduces, completely out of thin air, that an elaborate T-urf13-designing mechanism must exist in the corn genome (presumably he thinks this design mechanism was intelligently designed into corn). What supporting evidence does he offer for this quite ambitious hypothesis? He doesn't even try. For an encore, he goes on to explain that -- in essence -- evidence for evolution doesn't count if biologists dare to interpret it in an evolutionary framework. He uses an example of a fossil horse:

A simple way to state the problem with Cornelius Hunter's argument is that he is arguing that a Designer could do anything, so a Designer cannot be refuted by any observation. He is happy to have thereby refuted all the people who point out bad design.
But he doesn't get it that what he has just done is to admit that the hypothesis of a Designer is not science, as it predicts every possible result. If you predict every possible outcome, the ones that are seen and the ones that are not, then you have not predicted anything!
Unless you have some information about the Designer's intentions, her powers, how frequently she acts, and where, and on which organisms and which phenotypes, you ain't got nothin', no scientific hypothesis at all.
Paul King · 25 November 2009
The only good thing about Hunter's argument is that it sabotages the ID movements attempts to pretend that they are not religious. By claiming that arguments against design are theological arguments Hunter admits that he is only considering Gods as possible designers. And every time an IDer uses Hunter's argument they implicitly admit that they, too, follow ID for religious and not for scientific reasons.

I heard Hunter at Cornell in 2006 where he appeared to be an OEC (although possibly a crypto-OEC/"appearance of age" type).
Have his years at the Bible Institute of Los Angeles changed his mind?

"...most recently ID leader Stephen Meyer in his Signature in the Cell claim can never, ever, ever happen, because the improbabilities are so huge, and because “intelligence” is the only possible explanation for new information."
This seems to me to be the best strategy to expose the foolishness of the Hunter argument. Let the ID proponents make the predictions. Since they are almost universally ignorant of every finding in modern biology, they will inevitable claim that something that has already been observed is impossible or that something that will soon be discovered is impossible. Of course, they will only make negative claims about the potential of evolution to do this or that, but if they claim that GODDIDIT then they will have to explain exactly why she did it this way and no other.
SINE insertions and animal mitochondrial gene order are my favorite examples of this. They make perfect sense from an evolutionary viewpoint and no sense whatsoever using any kind of GODDIDIT or "common design" approach.
When the evidence is pointed out to them, don't just let them get away with hand waving, demand an explanation. If they won't accept the evolutionary scenario, demand an alternative. Force them to find a better explanation for ALL of the observed evidence. At least that way, anyone who is intellectually honest will easily see that they got nothin.
Our good friend Steve P. is an excellent example. On another thread, he claimed that endosymbiosis was impossible. When asked to explain the genetic similarity between animal mitochondrial DNA and purple bacteria DNA he replied that he had no idea, but still insisted that endosymbiosis could not possibly happen! He then went on to demonstrate a complete lack of understanding of the terms competition and selection. Well, he already made a claim and now he is going to have to come up with an explanation for the evidence. We'll be waiting.

Exactly how, when and why did God do this? Why did she make it look exactly like it would have if endosymbiosis was indeed responsible? Why all the evidence, some of it relating to arbitrary characteristics, that mitochondria are prokaryotic in nature? Was God not smart enough to create a mitochondria from scratch? This guy has a lot of splainin to do. Of course, I'm not optimistic, given the level of his understanding of basic biological concepts,

Re. Corny ever showing up here to discuss his claims -- Corny's been a bit gunshy ever since getting his own thread once
at AtBC. It didn't work out well for him.
Too bad he doesn't like making appearances any more, because -- as others also note -- he's transparently inane and a good stooge to poke at. I also get the impression he's now a quasi-old-earther (kinda like Sanford) depending on mood, wind direction, etc.

What is the ID explanation for any particular fossil horse species? Did the designer simply drop a couple of them (or a herd of them) into existence? Where they foals who never had a dam? Or adults who had never been foals? I'd love to hear an ID explanation.

Totally agreed with Frank J on this - keep pushing them for evidence. There are thousands of things IDers could be doing to support their case - sure, they push out the odd program now and again, but that's not good enough. Where's the Java applet where I can build myself a model organism and have its complex, specified information calculated for me? Where's the Irreducible Complexity tester, where a program pulls apart a structure a piece at a time and calculates the functional loss?
We write programs to demonstrate evolution all the time. Oddly enough, every program the ID side seems to write also revolves around evolution as well! Guys, your job isn't to disprove evolution. That's ours. Your job is to make a testable version of ID and disprove that.

The usual word-games. I once had an eighth-grader who argued that "acceleration" meant "to go faster", and therefore my definition of the meaning of it as used in Newtonian mechanics (change in motion) was wrong. And therefore Newton was wrong, as any fule know.
However, she knew perfectly well why she was arguing that. It was to waste time and get my goat, because she wanted to draw attention to herself and to make malicious mischief. I wonder what motivation Steve thinks he has?

Robert Byers -
I think Frank J has a point.
Under Christian theology, basically, either - 1) everyone who does not accept strict YEC is damned (some sects), or 2) those who accept Jesus as their savior are saved, despite different interpretations of Genesis.
If it is the former, then everyone who accepts mainstream science is damned, but so is every ID/creationist who does not outright preach YEC. (And those who may "secretly" believe it but pretend not to are damned for bearing false witness.)
If it is the latter, then "OEC" is no problem, but neither is the theory of evolution.
Either way, there is no logical reason for sincere Christians to be especially concerned with the theory of evolution. Either everything that deviates from YEC, including any expression of "ID" that deviates from YEC, and all of science, must be condemned, or none of it needs to be condemned.

Scott said:
"One of the early things that was needed in order for a “complex” organism to exist and survive/adapt was a mechanism by which that organism could evolve. It needed to evolve evolvability. That evolvability is what we see today, and what “we” just take for granted."
I am a little unclear on how one "evolves evolvability", could anyone explain that to me? I would appreciate it.

Interesting thought.
DNA repair mechanisms operate mainly at the level of single cells.
The parameters that determine the appropriate quantitative level of expression would basically be frequency of cell division, level of detectable mutation activity, and presumably to some extent, the DNA content of the cell.
An adult shrew brain cell presumably doesn't divide much at all, cells that maintain the whale gastrointestinal epithelia (or shrew GI epithelia) would divide a lot. Although quiescent DNA can and does mutate, mutations are much more common in the context of DNA replication.
Most of the regulation of these processes takes place at the level of the individual cell. To a large degree, that cell may not need to "know" if it is part of a shrew, whale, oak tree, or athlete's foot fungus colony.
Many DNA repair mechanisms are extremely ancient, conserved even between prokaryotes and eukaryotes.
The Wikipedia article is pretty good. References 40 and 42 seem to especially deal with this aspect.

I have been the object of one of Hunter's barbs (for my criticizing his vacuous discussion of biogeography in a Talk Reason/Panda's Thumb posting on Ann Coulter a few years back)so felt honored when he used exactly the same line of reasoning (God wouldn't do it that way reasoning can't be valid) against Jerry Coyne's recent book daring to mention the relevance of biogeography in evolutionary reasoning.
Anyway, I have no evidence so far that Hunter is anything other than a "I don't really bother about chronology" IDer rather than an explicit YEC guy. What I can attest to is that he fits all the hallmarks of the "tortucan mindset" (ability to not think about things that he doesn't want to think about) that I define in a lecture I gave last October for the Kennewick WA Freethought Society (a friend recorded it and posted it on YouTube for those curious about it ... just Google "Downard Tortucan Traps" and the link should pop up).

Why is it better to be white in some envoironments? Why is it better to be black in some environments (presumably you think that it is)? Is this something that scientists do not understand and only creationists can explain because of their "perspective" of the biblical flood?

Not being a biologist or actual scientist of any sort, I truly appreciate the clear replies given in this thread to sincere questions about genetics, gene transfer, mutation, evolvability, etc. So please correct me if my conception here is wrong:
Is it correct to think of cancer as an unwanted hazard of the ability of DNA to evolve? My thought is that DNA and its replication machinery could be "designed" much more robustly, so as to make mutations much more rare, and repair more certain. But that would greatly slow the genome's ability to mutate and thereby evolve, trapping organisms in disappearing ecological niches, unable to evolve fast enough to meet new environmental conditions (indeed most multicellular species can't, so 99+% have gone extinct). But the evolvability (mutability, plasticity) of DNA carries the penalty not only of harmful mutations in the next generation, but also of cancer in the individual (DNA damage switching on uncontrolled cell division which at that stage should be switched off).
And could it be an evolved trait in humans that cancers are relatively rare until after the peak reproductive years? In other words, the damage control systems work well enough to allow a "healthy" level of mutation in the population, but hold cancer at bay (usually) until after individuals have had a chance to reproduce. Then perhaps the repair mechanisms begin to break down, wear out, whatever, since the individual's evolutionary role is complete: he has lasted long enough to successfully reproduce, and his evolutionary benefit to the species is thereafter diminished.
And something I wish PT could do: Could you set up a separate thread, section, or whatever, for usual lurkers (like me) who have sincere questions about details of evolutionary theory and practice that all of you pros could address? Not a thread for trolls who are sure they can demolish all of modern science with a killer question that "darwinists" can't answer, but one for folks who really want a little education. Just post a "no trolling" policy--there are other PT sections for argument.

Later it just stays in the same gear as there is no need for change."
This is all completely made up nonsense without a shred of evidence.
Robert, do you know the current distribution of indigenous human skin colors on the surface of the earth? Do you know that if someone migrates to a different lattitude that their skin color does not change instantly?
Do you know the selection pressures acting on human skin color? Do you know the problems that are caused by migrations of people to areas where their skin color is no longer adaptive? Do you know why white skin is not always the most adaptive skin color? Do you know why black skin is not always the most adaptive skin color? Do you know that this is something that is very well understood by scientists using sound evoutionary principles?
Do you know that this has absolutely nothing whatsoever to do with the imaginary magic flood? Do you know the explanation that the Bible gives for differences in human skin color? Do you think that that explanation is correct?
Do you know anything at all about anything? Do you even know the genetic basis of human skin color? Do you think that displaying your ignorance is somehow beneficial to yourself or anyone else?
