"Thank you for the welcome, and no, I have not been lurking. I was invited to come here by our mutual friend, Bob, who saw me posting on a secular Creation VS Evolution forum. To tell you the truth, I would MUCH rather argue creation VS evolution with believers as the basis if YEC (young earth creationism) is the Bible - which is most usually scoffed at by secularists."
I agree. I like to talk about this, but I have never been willing to venture off to any other sites. I have lurked there on occasions, but never often. A problem around here is that most of the people who once discussed it at this site no longer come around since they discontinued the dedicated forum. I think the moderator for it got too busy and no one else wants to get into that mess. So, there are only a few people that post regularly on each side. My loyal opposition seems to have been reduced to "I don't want it to be true so it must not be." You seem to be fairly informed and could make this much more interesting. There is one other well informed individual 'round here, Helen, but she is too busy to pop in much. Her husband is Barry Setterfield of the decaying speed of light fame.
"Adaptation does not mean evolution took place. It is, however, strong evidence that the bacterium has some seriously wonderful design. It was designed for a wide range of environments as well as with the ability to adapt to new situations."
Well, yes, I would disagree. Let's go back to the most basic definition of the theroy of evolution (as opposed to the observation that evolution has actually occurred / occurs). The change in allele frequency. A new and useful allele has appeared. It made the bacterium more fit for that environment and so bacteria with it were more likely to survive and increased their numbers. I call it evolution. Any type of adaptation I would call evolutiion.
"Would you agree that God designed the bacteria? Do you think that God created Bacteria discreetly as he did Adam?"
That is a tricky one. No, I do not think any of the lifeforms we see today were discretely designed. I think the evidence is against it. But, there may be a scant piece of common ground, but I do not think you will take it. Abiogenesis is something that we will never be able to tease out of history. We will never know for sure how that happened. As a Christian, I have no problem with God sticking that first population of simple life on the early earth knowing in His wisdom where things would end up. If you look back above, you will see that I did a paragraph on the genome being evolved to evolve because of how substitutions to the code affect proteins. Maybe we could agree to designed to evolve and disagree on the magnitude of that evolution.
"Secondly, (to address your 1st point) I would argue that nuclear DNA is what is most important."
Well, I would agree. But, when advantage is conferred on an individual, I don't think that it matters where the change comes from. Thinnk about how much we have learned in the past several years about how non-coding parts of the genome affect traits.
"Here we see God creating creatures and commanding them to reproduce after their own kind. "
Do you think you are a creation of God? Did your parents not give birth to you? Is there a contradiction here?
In evolution, change is slow. A creature never gives birth to something that is not of the same species. But with changing allele frequency within a population with time, a population can become something new. It is a misrepresentation of the process to suggest that it means that a "sea creature would reproduce after it's kind to give birth to a land animal." Evolution follows the reproduction within kind. It is just that kind changes with time. Even you accept speciation. And apparently new genera, too. Nothing stops that process from going higher. I believe I went over a couple of examples for you in a very general way above.
[snip information discussion]
First, nice answer on the apoprotein. You make that point well.
But I do not think that you have demonstrated that mutation is always an overall degrading process. With point mutations, you have the chance of giving a protein the ability to better do its job. No loss of complexity there. Even better, in duplications you now have two copies of the same gene. One can maintain function while the other mutates. If it turns into junk, nothing was lost. If it turns into something useful, then something was gained. And, as mentioned before, since there are many different classes of proteins where similar structures perform a wide variety of functions, we have circumstantial evidence that this is an import method of producing new and useful genes.
[snip discussion of skin color]
But, sticking with skin color, we do not actually see that humans are either full on or full off in their pigment production. They exist on a continuum. Each adapted to his environment.
"Ah, but again, this uses the unifomitarian concept that we can interpret the past by what we observe in the present (the thought that things are now as they have always been). It may very well be that, as I have indicated, there were many functions which were not polar, but dynamic and mutation and 'micro-evolution' (sometimes called speciation by creationists) is acceptable within the creationist paradigm."
First, if you oppose unifomitarian you have the burden of proof to show us that things actually operated differently in the past.
Now, in the real world of today, we see a wide variety of different versions of the same allele giving rise to different versions of the function. These varieties of genes with adapted function goes against the idea of no new "information."
[snip junk DNA discussion]
I will fully agree that we are learning that much of the "junk" is actually useful. Doesn't change that a lot of it is truely junk. I made a specific example. A large proportion of the genome is retroviral insertions. Humans essentially share all the same insertions. If this class of junk was added during the last few thousand years, then there would be a lot of variance in what LTRs were in which humans. You would even expect to see variation from generation to generation. But, we do not see this. The insetion of a LTR into a germ line cell that is used for reproduction and passed on seems to be a very rare event. More directly related to evolution would be the several LTRs shared between all the apes including humans.
