Creationism and Baraminology Research News

This blog has been superceded, and is only here for archive purposes. For the latest articles, please see us at our new location!

An ongoing list of creationist research projects. This is not a creationism-verse-evolution site, but a site to publicize the research work done by members of the creationist community and the intelligent design community, or research work by the science community at large constructively relating to creation topics. Evolutionary critiques may be included on occasion but only under special consideration, and especially where the research pertains directly to developing a creationist model.

Kurt Wise on the Evolution of Creationism

It appears that the Geological Society of America had a conference which included a session on the interplay of geosciences and religion. All of the abstracts are interesting reads, but in particular Kurt Wise's is interesting for the creationist perspective:

A review of the growing technical creationist literature suggests that not only has the creationist perspective increased in sophistication and scholarship, but it has also become less political, polemical, and critical. At the same time, neocreationists disdain the errors and misrepresentations which persist in the popular creationist literature. If the trends internal to creationism persist, we can expect future relations between creationists and evolutionists to be characterized with less litigation, rancor, and hostility.

May it be so!

Against the Creationist Metaphysic

I don't normally post creation-vs-evolution debates on these pages, however, I don't mind posting counter-arguments to creation and specifically creationist methodology. Doppleganger posted a link to a great article to think on in the primate baraminology post, and I thought the quality of the argument was significant enough to share with the rest of you:

Real soon now

Sorry for being out so long. I should be back Real Soon Now. The company I work for is moving to a newly renovated building and it has been nonstop work trying to get everything ready and going.

I have several things on my list to talk about, specifically eco-devo (yes, that's eco-devo, not evo-devo). Anyway, hopefully I'll be back to blogging this week.

Contingency and Natural Form in Biology

Denton recently had a paper in the Journal of Theoretical Biology about the origin of form in proteins. In it he makes an interesting point about one commonality that both creation and evolution have -- contingency. The nature of the contingency in creation is different than that of evolution, but they are both primarily contingency-oriented ideas. What is meant by that is that the origin of biological form is primarily the result of history -- in evolution it is the history of happenstance interaction of molecules, and in creation it is the history of the Lord's creative acts (whether you take a long or a short view of that history).

Another idea is that of platonic forms. The idea is that biological systems follow a form that is built-in to nature. Denton's paper, The Protein Folds as Platonic Forms: New Support for the Pre-Darwinian Conception of Evolution by Natural Law, points out one aspect by which it appears that the platonic concept might be true -- the rules of protein folding.

The thesis is, despite the huge number of total proteins that we know about (hundreds of thousands or more), there is really only about 1,000 folding patterns that all of these proteins fall into. In addition, in these folds, the structures are stable -- they do not require outside help to keep them from being damaged through minor perterbations.

Thus, the protein folds cannot themselves be described through contingent language (well, not quite, but we'll get to that in a minute). The proteins folding patterns are part of the laws of physics, and are not necessarily encoded anywhere. They are "platonic forms" in that they are ahistorical, and arise by necessity anywhere that a protein-based system would be used.

The discovery of protein folds following platonic forms leads naturally into asking what other sort platonic forms might be available. I have heard that D'Arcy Thompson's work, On Growth and Form, talks about the laws of form that living things follow. While I own this work, I have not yet had the time to go through it. Likewise, I think that Following Form and Function has a great deal of material about this, but again, I have not read it.

So how does this affect creationary theory? Evolutionary theory? It doesn't affect either one very much, per se. The fact that we don't see life forming spontaneously today indicates that while certain parts of life may be governed by platonic forms, life itself is still very much contingent (and theistic philosophers will also note that the laws of physics by which the forms come about are likewise contingent, but that is really outside the present discussion). Creationists are fully within their rights to see that the God who designed physics also designed creatures to make the best use of it, and designed physics in such a way as to support life.

It does, however, have some effect on some of the arguments that are used against creationists about homology. If it may be allowed that some parts of organismal form is not contingent, but in fact one of only a few possible complete arrangements, then homology, in addition to being part of a "common design" as is often articulated, may be the result of there being only a finite number of organismal forms available. So, in addition to homology being a common design patter, homology may be also be an intrinsic property of physics, having nothing at all to do with an organism's history. Note that this is not evidence against evolution per se, only showing another way that the evidence used against creationists does not necessarily imply what the evolutionists say it implies.

Anyway, the point of all of this is to spur our thinking in other directions. That we need not think strictly in terms of contingent features, but also let ourselves think of the forms that may be bound up with the laws of physics that are controlling organismal form.

One thing that the paper pointed out that was really interesting is that many biologists throughout history have actually viewed function as secondary to form -- that function is a secondary adaptation to a natural form. An interesting viewpoint, and one that we can probably learn a lot from.

Ideas for Creationist Research in the Secular World

I always wonder how many creationists are in the biological sciences, but are keeping a low profile in order to keep their jobs. First of all, I would encourage anyone doing so to think long and hard about whether or not Christ is served by such actions. Perhaps He is, I don't really know. But it certainly is something to think about.

Anyway, if you are in the biological sciences, or are thinking about getting into the biological sciences, but don't know what to research on, this post is for you. Of course, you, actually being in the biological sciences, probably know more about this than I do. But hopefully as an outsider I can provide a fresh perspective on the situation. This should be both (a) interesting to a creationist, and (b) able to get secular support for such research.

Look for more examples of the directed adaptation of an organism through mobile elements

There is already at least one example of an insertion sequence as an activator of cryptic genes

Some suggested studies for this area might include:

  • A study of C3, C4, and C3/C4 photosynthesis, and try to induce a change from one to the other. Todd Wood has hypothesized that this could be because of inactivated genes. If you could simulate sufficient environmental conditions to do the switch, that would be fabulous.

  • A study of symbiotic mechanisms. I personally have a gut feeling that symbionts are an adaptive process, and that organisms detect what other organisms are in the area, and can, most likely using transposons, develop appropriate symbiotic behavior with those creatures. A good study specimen might be orchids, which seem to produce symbiotic behavior quite easily. Showing that animals have pre-coded adaptations to certain types of organisms indicates that these adaptations do not arise a piece at a time, and are a part of a plan, not happenstance.

Generation of de novo genes

Studying the nylon bug could prove interesting. It has applications to all sorts of areas of creationary theory. For example, the generated gene occurs in both flavobacterium and pseudomonas with a high homology between the two genes. What does it say when generated genes have a high homology? What does that do to arguments from homology? In addition, it appears that this gene is actually pre-prepped for change, with a lack of stop codons in the antisense strand [the abstract says "the presence of such rare NSFs on all three antisense strands of the nylB gene family suggests that there is some special mechanism for protecting these NSFs from mutations that generate the stop codons. Such a mechanism may enable NSFs to evolve into new functional genes and hence seems to be a basic mechanism for the birth of new enzymes."]. In addition, there were many point mutations and transposon activity in the birth of the new gene. So, by what process did this new gene arise? Note that this also has a lot of impact into the environment, so that we can know if we can mutate bacteria to eat some of our trash.

What does having a gene that is open to mutation say? For one thing, it says (a) it is really rare that a gene is open to so much mutation. It also says (b) that such mutations require specified mechanisms to occur -- the evidence doesn't indicate happenstance. Finally it says (c) the mutations were directed at this particular gene (imagine what kind of error catastrophe would occur if this kind of mutation happened genome-wide).

Adaptive Mutagenesis

A good research topic would be adaptive mutagenesis. Some ideas along this line would be:

  • What are the actions of the different DNA polymerases, and why do cells use one over the other

  • What kind of specificity occurs during adaptive mutagenesis. It is widely claimed by this experiment that adaptive mutagenesis is just a lot of random mutation + natural selection. However, I still don't see the mutation process as being random, for several reasons.
    1. While the environmental stress affected more than just the Lac- genes, it did not affect all genes, which is evidenced in their paper with the follow quote: "Thus many, but apparently not all, chromosomal loci hypermutate in association with Lac+ adaptive reversion." (there were no Fruc- mutants in the revertant colonies). This indicates that there may be some mechanism that the cell uses to figure out what to mutate. Even if it is just selected amplification with a mutagenic DNA Polymerase, how is the gene to amplify (and thus mutate) get selected?
    2. What are the specific mechanisms of the DNA Polymerases? I'm sure this is already covered in the literature, but a more relevant question is "which DNA Polymerase activity promotes adaptive mutagenesis of which genes, and how does the cell know which one to use?"
    3. If there was a spout of hyper-random-mutation, such that in nearly every case there was adaptability, it seems like this would have to be large-scale genome bombardment, such that would lead to error catastrophe. The fact that it does not indicates that there is a mechanism which either partially specifies the mutation or prevents error catastrophe in critical components.
    4. Above, we discussed a certain gene which is activated by an insertion sequence. What causes an insertion sequence to be activated in one stress condition, while adaptive mutagenesis is activated in another one?
    The answers to these questions can greatly help advance creation science further, as well as secular science.

  • What types of genes can undergo adaptive mutagenesis, and which ones cannot?

The Function of Alternative Splicing

Alternative splicing will change the way we view DNA. What we need to know is (a) how does the cell know when to change the splicing, and (b) is there a way to detect within the DNA where splicing can occur. I'll present some good papers on alternative splicing (hopefully) shortly.

The Semantics of the Genome

Semantics is probably the greatest evidence of intentionality in a coded system. Semantics are the constraints under which change operates. In general, when coding a computer program, each design purpose (apobetic information) gets coded as at least one semantic constraint. While there are some apobetics which do not reflect this, the existance of semantics in the genome imply an apobetic origin. Quantifying the genome semantics using something akin to Type Theory in computer science would go a long way to showing design.


I'll probably add to this list as the week goes on. Note that almost always the "random mutation" is the presupposition, which is easily refuted by examination. The Darwinist idea is that life is contingent, but contingent on happenstance. All that needs to happen is when a secular biologist gives up and says "it was random", you go in and say "no, here's how the design works".

If you have any ideas for research projects, please post them in the comments!
