It takes an observer?
If it takes an observer to collapse a wave into a particle...
This is a big "if". I don't think that it takes an "observer" if you require that to be a sentient thing. Would you care to elaborate on why you think it might take such an observer?

Re: It takes an observer?
It seems it does, Ned, but it's not me proposing this, it is well known physicists both dead and alive.
Actually, that is an old expression of the idea. Recent work with quantum entanglement shows that you have to have no interaction whatever or the entanglement is destroyed. It does not require 'intelligent' observation. It simply requires some interaction with some other part of the universe.
The idea that an intelligent 'observer' is required is something which has grown out of the everyday idea of "observe". Any observation requires some interaction with the system understudy. It does not require that an intelligent person examine the result of the interaction. We use the word, colloquially, to mean the persons examination. What actually 'collapses the wave function' is the interaction.

One attribute of the designer then...
If the designer is the observer of quantum mechanics, then the act of observing the right place at the right time could be the mechanism. I predict that someday QM and ID will support each other in this reguard.
A lot still needs to be done in QM, however it is true that most interpretations currently suggest an observer. That alone should be enough to make most athiests/agnostics pause.
Well, this does tell us something about the nature of the designer then doesn't it?
The designer can not be the Christian God as described by almost all of His believers can it? It seems unlikely that the ID folks actually wanted to disprove the existance of the Christian God but that is a side effect of this QM idea.
The designer is clearly not omniscient is S/He/It? If He was the all observations have been made already. All wave functions are collapsed. Why then does the double slit experiment ever produce the interference result?
I wonder who or what the designer is then now that we have eliminated one popular possibility?

Re: It takes an observer?
Not correct, I'm afraid. First, you are confusing the double-slit experiments with the quantum erasure experiments where entanglement occurs. Entanglement is not studied in the simple double-slits I was discussing.
Could you explain more why there is that distinction. I'll have to do some other reading too I guess.
It can be the Christian God if one chooses to view this theologically rather than scientifically.
Well, since science works with natural evidence it has to be viewed theologically doesn't it? Most folks seem to consider the Christian God to be omniscient don't they? That suggests to me that He/She/It is an observer of all events for all times.
Or, one can just stop at quantum mechanics and be done with it.
I thought that this was a "foundation of ID" that you were putting forward. Are you suggesting that quantum mechanics is an "intelligent designer"?
It could be omniscient, science does not tell us it is or isn't.
If the designer is omnisicient what does that suggest about the observations of all quantum events?
You certainly haven't eliminated any possibilities. Just because you only describe my hands does not logically extrapolate to, "therefore, there must be no arms, legs, brain and body attached to them."
As I noted when I started: Most Christians I am aware of consider the Christian God to be omniscient. If I can say from what you are telling me about the QM issues that the observer is NOT omnisicient (since it does not collapse all wave functions ) then I can say that the designer is NOT the God that a majority of Christians believe in.
If in discussing some unknown creature I can say nothing about the arms, legs, brain etc. but I can say that the hands are claws then I can say that we are not talking about a human being. I have eliminated that possibility.
It seems to me that eliminating omniscience might still give us a God but it is not the God of the majority of Christians. I am inclined to think that without omniscience I also don't get omnipotence but that is too far from the topic at hand.

Gradualism
Nah....Darwin didn't reject gradualism he necessitated it:
Did you not read the direct quote from Darwin just above your post???
This is an error which I laboured under too. I thought that Darwin demanded a constant rate of change by evolutionary processes. It is clear from the given quote that he was, in fact, a "punk eqer" from the get go.
Punk eq IS gradualism too. There is not suggestion that major changes arise in single steps. That has been rejected for a long time. Speciation can, on some occasions arise quickly in single steps but then species can be separate while being very, very, very similar.

Argument from analogy
Surely you are familiar with an analogy. They work pretty good in logical argument. So again I ask you. Can you refute the 747 argument? Can you show how a tornado could sweep through a lumber yard and build a house? I mean if you cannot, then they seem like pretty good analogies to me to use to make points about spontaneous complexity.
Analogies are exactly useless in a logical argument unless they reproduce the situation being argued about. Analogies are useful as an explanatory tool if the real case is too complex for someone to "get" right off. They can then be used as a jumping off point to understand further.
Even for the simplified explanation use they have to model the real situation under discussion adequately or they are just a source of further confusion.
It appears that you think the 747 from a junk yard by tornado is a useful analogy.
However, what are the most important points to understand about darwinian evolution: the combined action of imperfect replication with selection.
Are either of those present in the analogy you offer? No, not at all. Aircraft do not f**k! There is no selection of anything by a tornado. Your analogy doesn't need to be refuted in that it isn't analogous to the situation under discussion. Not even close.
It is utterly ridiculous statements like this that seem to be characteristic of a lot of the ID movement. Is it any wonder that it isn't taken seriously?

Re: Argument from analogy
That is a demonstration of the fallacy in action. As you can see, it has not a thing to do with what I was discussing with Ooook.
In this case the analogy you use doesn't even look like the subject under discussion. This is not the fallacy.
You would change the very fabric of modern life if you denied everyone from using analogy to communicate. Teachers use this every day in communicating a concept to students.
As I noted it is a useful form of communication. It is not a useful way to prove or demonstarte anything.
Horse hocky. In fact, if one accurately reproduces the situation then it is no longer an analogy. You don't seem to understand what an analogy is:
I understand perfectly well what an analogy is. It might say something somewhat meaningful about something else if it reproduces the important points of the more complex thing that is being analogized. However, it never does more than indicate something it can not prove anything when it is in some way "dissimilar".
Nonsense. You've never heard the term take a flying f**k?
You seem to have a habit of attempting to be funny when you don't have an answer for the points raised. Perhaps you would be more credible if you actually attempted to show that the 747 analogy is in any way useful when there is no imperfect reproduction or selection involved in the analogy. Which makes it not only dissimilar in some respects but dissimilar in the important respects.
Now that you have made a funny, perhaps you would like a chance to try again.
