Everyone, I believe that the extraordinary amount of irrelevant and "read Meleagar's mind to argue against his or her beliefs of the nature of the Intelligent Designer"-type statements and questions are unintentionally changing the argument made by the original post. Please read Meleagar's conclusions carefully and do not make further assumptions and propositions that you would expect to follow after these conclusions from him or her. To clear this up a bit, I believe that there are two arguments being made:
1) Intelligent Design exists as an entity which changes populations over time, therefore it must be included in the definition of Evolution so that Evolution can accurately model all known causes of change in populations over time.
2) Evolution does not allow for Intelligent Design, therefore it is flawed.
The arguments made should be based off of the support for or the rebuttal of these two conclusions. Because I am a hypocrite, I will respond to all irrelevant passages =D.

Meleagar,
Very good post! I find your logic very easy to follow and your inferences, for the most part, very agreeable. I just want to quickly address some points that other people make that I disagree with before I address yours.
(-sigh-) After finishing those responses I added this sentence to recognize my silly prediction of "quickly addressing" the other points.

Alun,
Well, I think the ambiguity of this term is actually rendering your defined "big issue" relative to what you are inferring intelligent design means in a particular circumstance, such as in Creationism.The bigger issue, though, is the ambiguity of the term "Intelligent Design." The issue is not whether you want to call the results of human genetic engineering a result of natural selection. The issue is whether you want to call evolution on earth according to the fossil record a result of natural selection.
I don't think that Meleagar is trying to explore any specific case in his first post. It seems as if the "big issue" that Meleagar's post is addressing is that the scientific study of evolution does not allow for intelligent design to be a viable evolutionary process, even though it is clear that intelligent design is used by humans to change organisms and populations over time. Therefore, because intelligent design exists as a method of change in populations over time and evolution does not encompass this method within its definition, evolution, as defined currently, is flawed as a method of modeling change in populations over time.
Just for the record, I disagree with Meleagar because I believe evolution does allow for intelligent design to be a viable evolutionary process. I agree with your perspective on Inference 8.

Wowbagger,
Well you're right in that this argument is logically flawed, but I believe that the choice to use this illogical method is too broad of a generalization to be making about religiously motivated ID.The problem with religiously motivated ID (and trust me, they all are) is the reasoning
'I personally can't explain how x [insert a complex feature of organisms] came into existence gradually through random mutations, thus it has to be designed.'
Oh wow, really? That's pretty cool, actually. However, I do not think it is proper to induct that an organism was intelligently designed because a poem is in its DNA. Exactly how does one write a poem with four letters, anyway? (genuine curiosity)Craig Venter writes whole poems and passages in English in some ATGC code in his artificially genomed bacteria, so if they escape into the wild and we catch them again later, we will know that they were designed, or at least tinkered with by humans or some other intelligence.
Hmm. Well what exactly is artificial selection in this context? I believe that artificial selection is indeed dependent on human intelligence in its original definition. The word "artificial" implies man-made, does it not?And one more thing, dogs or crops aren't really intelligently designed. Artificial selection is still part of evolution, some kinds of fungi actually only grow in ant heaps of a specific type, they've been cultivated by these ants for millennia. So artificial selection is not just a human phenomenon. Genetic engineering is though.
Also, remember...
So, I would debate that artificial selection is a branch of intelligent design. Since crops and dogs are intelligently, directly manipulated to achieve a goal, this falls under "intelligent design." However, this is not sufficient enough for this thread because of the incredible ambiguity of Intelligent Design's definition. We must further state that because this goal is to change a population over time, this case in study is an example of evolutionary intelligent design, assuming that evolution allows for intelligent design under its definition. I believe that it does allow intelligent design in its definition while Meleagar believes that it does not.Definition: Intelligent design is the scientific theory that some phenomena are best explained as the result of an intelligent, directed manipulation of materials and forces to achieve a goal
In the case of the ants and fungus, I believe that it is proper to say that this relation was one that involved a being with intelligent capabilities (the ant) that directly and intelligently manipulated a population of fungus to achieve a goal, therefore this is an example of intelligent design. However, the actual goal of the ants is unknowable and I believe that it would be more likely, (since they really are not closely related to any species that we would consider "highly intelligent organisms") that the goal of the ants was not to change the population of fungus over time, but rather to reap the benefits of what the fungus offers in its present existence. Therefore, the fungus population changing over time was not an intended goal of the ants, therefore this is not Evolutionary Intelligent Design, which is what we are exploring here. Although this is a process of intelligent design in respect to simple survival, evolutionarily, this process of the population changing over time is more accurately modeled by natural selection and genetic drift.
Well, I think it is fair to assume for this thread that all biological processes exist because of a cause for their existence. I do not think that it is fair to assume that any biological process or phenomena that does not seem to be caused by other evolutionary means can be identified with the only rational cause left from what is observed. The reason is because we can never know if we have observed everything in a particular entity.And I suppose one other way for scientific enquiry on ID is to ask the 'what for' question. If future researchers find tomatoes that glow in the dark for no apparent reason at all, especially if this is hurtful because it i.e. attracts vermins, then they would have evidence that someone (rather unintelligently) messed with the tomatoes.
For example, if a species of tomatoes glows in the dark and this biological phenomenon is inhibiting and is in absolutely no way beneficial (even though the benefits probably just have not been identified) to the species, it is not fair to assume that Intelligent Design is the only rational cause. The reason we cannot fall back on this cause as the right answer, even if there really are no known current benefits, is because this effect may have been beneficial at one point in time and is now only inhibiting because of environmental changes that have not been considered or are not able to be observed, or because this effect could actually be a "side-effect" (such as we discussed in the love thread which I still not have read your response) that has not actually been identified of a single evolutionary cause that actually causes the existence of a completely separate, positive effect.
p.s. I am very sorry for the brutality of that last sentence haha.

Muddler,
Ugh! Why wasn't your post before Wowbagger's?! Haha. I pretty much just took the following passage...
...and made an essay out of it. I wish I had read this first haha.Not only do parts of complex systems sometimes get exappropriated for another function by evolution, but not all surviving mutations can be classified as either adaptive or deleterious. There is stuff in genes that is indifferent and that can be appropriated as well.
As for your second post, I find it completely irrelevant to the subject. Meleagar is not arguing anything but that evolution is not a sufficient-enough cause for change in populations over time unless it is inclusive of Intelligent Design. So, the position you take should be either for or against this proposition; I don't think that bringing up discussion of an intelligent designer that "cares" about us or the existence of extinct animals is relative in any way whatsoever.

Unrealist,
Personally I do not see how Meleagar intended to conclude what you stated in your last sentence. All he intended to conclude was that Intelligent Design is a currently existent method of population change over time, and therefore must be included in evolution's definition so that one word can be used to encompass all known methods in which populations change over time. He or she argues that the current definition is not sufficient enough, so that is the argument that should be addressed.Meleagar,
Wat you say about humans deliberately manipulating other organisms is not in dispute but humans have only been around for a very short time and have exhibited very little progress in these activities, certainly not enough to conclude that such deliberate manipulation as humans have carried out is a reasonable explanation for current genetic diversity.

Belinda, as usual, I sincerely do not understand what you are trying to conclude in your arguments and I don't want to answer based on assumptions I make, so I'll just apologize.

Meleagar,
At the beginning of my post I reinstated the two conclusion that I believe you were trying to assert. The first one I agree with and the second I do not.
The reason I disagree is because I see error in inference 8.
As Alun stated, the NAS wrote...8. Inference: current evolutionary theory cannot account for the existence of genetically modified or selectively bred biological organisms because it has no way of accounting for an intelligent, teleological selection process or infusions of designed genetic materials; in fact, current evolutionary theory definitionally precludes such processes and activities from being considered at all.
and I do not see how inference 8 could be derived from this definition. Could you explain why Intelligent Design cannot be an evolutionary process according to this definition of evolution?Evolution:
Evolution consists of changes in the heritable traits of a population of organisms as successive generations replace one another. It is populations of organisms that evolve, not individual organisms.

Natural selection:
Differential survival and reproduction of organisms as a consequence of the characteristics of the environment.
Sorry I don't have much to respond to. I find the rest of your argument very convincing.
