Comments

Wow, I'm impressed. Link to come shortly.

Although, I have to say, he lost me here:So how do we deal with atheists who use a government monopoly on public education to indoctrinate our children?For someone who's warning against an "us versus them" mentality, that sure sounds like an "us versus them" mentality. And I'm sorry, but the whole atheistic government monopoly on public schools rhetoric is a bit heavy handed, don't you think? It all stems from an assumption that religious neutrality equals atheism; if that's the case, then reilgious minorities are pretty much screwed wherever they go.

That was a comment for my Christian World View friends, hence the introductory phrase. I disagree with many Christians' desire to change public schools. My preference is to provide an alternative. This point was made a bit stridently- my apologies.

Steve,

Have you read Darwin's Black Box, cover to cover?

Very interesting discussion! What I am curious to know is whether or not you feel that what is written in the first chapters of Genesis is literal or not. Am I right in assuming you think not literal? I'm just trying to get a grasp on where you are coming from. This is such a charged subject and there are so many ideas floating around out there. My human nature wants me to categorize them so I can understand them better :)

Have you ever read any books by Dr. A. E. Wilder Smith?

to Phisch,

Yes you are correct regarding Genesis, as I mentioned in part 1. I am not familiar with Wilder Smith.

What a fantastically well-written, and well-thought-out piece! Thank you very much: I have been attempting to say something similar all over the place, but not doing it nearly this well.

Thank you very much!

David,
Thank you for your encouraging words. I'm afraid that the lack of comment means that it has the bounce of a bag a grass clippings. After we get past this tragic day for Jeff and I, maybe we can pick up with some comments on the Vatican's announcement regarding this topic.

Here is a parallel thread discussing Steve's post

Live Journal

Thanks for answering my question (actually, clarifying to me what you already wrote :)

Dr. Wilder-Smith's background is pharmacology but he's written a number of books on biogenesis. I've not read any of his books (besides his biography) but his tapes are available online and might be interesting since they're germaine to this topic.

Kudos to Steve and Jeff for one of the best discussions on this debate in a month of Sundays. I do want to add a couple of things though. Steve says ID and Evolution (capital E) are both unfalsifiable, and I'm inclined to agree with him, at least at this point in time. He then goes on to site the chromosome differences between humans and other primates as indicative of common descent from the latter to the former.

I bring up these two points in unison to remind folks that the real debate about ID is not over "common descent" or "descent with modification." Most of the well known ID advocates accept some form of common descent (Dembski, Behe, the pseudonymous Mike Gene) even if it's not necessarily universal common descent. The real debate is over what unaided natural processes in general and what natural selection in particular can accomplish. Are there biological "machines" (like the flagellum) or processes for which intelligent agency is the best inferred (though not the only concievable) explanation? That question, at bottom, is what ID is all about.

I suspect where ID advocates don't come clean is that we don't yet have the tools (in terms of computer models, probability theory etc. -- I mean, we can't even predict the weather for more than about four days ahead of time) to ask the question in a way that's meaningful to science qua science. I do think it's fair to ask the question though, and to try and build the groundwork for the day when/if we do have the tools. The Evolutionists (capital E once again) seem, by and large, determined to deny that the question could or should ever be asked to begin with. They aren't coming clean either.

to jayman:

I appreciate your comments very much. The points are well made and well taken. It is certainly true that my fused-chromosome example does not disprove ID and could in fact be incorporated into an ID paradigm. Here's a twist: Has anyone heard of the technique, "directed evolution"?

This is a technology that is used to great effect to generate novel or greatly improved protein molecules (also DNA/RNA "antibodies", computer programming and design,- with less success). This example was given as a rebuttal to Dr. Skell's article (mentioned in part 3 above) and a "proof" of Evolution. Since I use this very exciting technology, I like talking about it.

I would be happy to provide more detail to anyone interested, but this is a thumbnail sketch of how it works. The scientist generates a very large library of random sequences (protein, DNA, RNA, computer code, etc.) and places them under selection to choose the best performer. It is essentially the opposite of what is called "rational design" of drugs. Some say it is a proof for Evolution. I am not convinced.

What do you think? Anybody?

My $0.02.

Directed evolution is an oxymoron ... in the same class as "undirected design." For that reason alone, I don't see how this would be very compelling proof of the kind of Evolution that everyone really cares about.

I think the intentional use of natural selection to develop antibodies is a cool concept. Kind of like throwing a bunch of stuff against the wall to see what sticks.

What concerns me is that similar thinking (directed evolution) is what fuels eugenics. In other words, be intentional about applying natural selection to breed the purest human beings.

You (Steve) have a worldview that keeps prevents you from endorsing such an atrocity ... but those without a transcendant moral code could easily say that directed evolution works wonderfully for antibodies, why not apply the same principle on a larger scale? After all, we all want to be healthy and happy.

Jeff, you are not just blowing wind with the claim that some in the scientific community advocate genetic engineering of humans to improve certain characteristics (intellegence, innate immunity, cancer resistance, longevity, etc). It is considered the next step in human evolution. A close colleague of mine openly supports such "humane improvements." I consider this a real threat in our modern society and perhaps one important reason for a total and permanent ban on reproductive cloning.

But getting back to directed evolution, it is not the same as above, or a breeding program- and could never be done (technically speaking) on humans because of the number of trials necessary (millions) to get a success. It is a specific laboratory technique that has a very short time scale (weeks) that works primarily on molecules not organisms.

Modern eugenics is a real threat, but "directed evolution" is just not the specific tool to do it. It does has an ominous sound to it though- maybe if I capitalize it...

"But getting back to directed evolution, it is not the same as above, or a breeding program- and could never be done(technically speaking) on humans because of the number of trials necessary (millions) to get a
success."

Correct. I realized that. I guess I saw a philosophical similarity between the two topics inasmuch as both are an attempt to harnass and leverage evolution.

The motto for the human eugenics movement was "The Self-Direction Of Human Evolution".

I realize that the technique you are talking about is, at a technical level, completely different than eugenics / breeding / or genetic manipulation.

Back to the question you asked about directed evolution.

I don't think it offers any compelling proof for Evolution. The kind of Evolution that I am interested in involves undirected, random, gradual increases in complex systems that will break if one component is not
functioning ... like morphing from a light sensitive spot to an eye with a pupil / cornea / retina / lens etc without ever going blind.

The type of technique you are talking about does not contribute to that discussion without a lot of imagination and scientific faith, imo.

It is an interesting technique though. Is it completely hit or miss, or do you have some way to reduce guesswork and focus on more promising sequences?

The selection technique enriches for the desired, but unknown molecule. The procedure is repeated through several rounds until one or a handful of highest performing molecules (peptides, for instance) are left. So instead of testing known compounds, you generate millions of random unknown molecules, select the best, then identify it/them.

I agree that this technique just proves that intelligently directed evolution works- in a limited fashion. New organisms or species have never been generated to my knowledge, just improved proteins and nucleic acid aptamers (DNA "antibodies"). It is just that some proponents of Evolution draw the conclusion, "because evolution works, Evolution must be true."

I just wondered if you or your readers had heard of this technology.

There is a lot of equivocation on the word "evolution" ... to some it means natural selection ... to others it means common descent ... to others it means change over time.

Precise language is half the battle. I'll bow out and see if any readers want to engage you on this discussion about directed evolution (funny term, if you ask me).
