Phospho writes:Because the author believes that evolution has been proven (because he has been unwittingly duped into the bogus terminology and word-games that evolutionary theorists dish out), it is not his fault, he just got caght up into it. Does this make any sense to you? I understand what you're saying, but can see no basis for it. It's interesting that you think terminology has something to do with the acceptance of the evidence supporting evolution (it's more accurate to say it this way than to say "proven"), because your approach has been primarily terminological. You carefully define your terms so that there's no term for "beneficial mutation", then claim that therefore there's no such thing. Meanwhile people have been showering you with examples of beneficial mutations, and there's a running score on discussion of some of those mutations if you've seen Message 180. You can take each supposed beneficial mutation one by one and argue that it isn't really beneficial based upon your special definition of beneficial, but meanwhile the process of evolution effecting environmental adaptation continues to be observed in the world around us. --Percy This message is a reply to:Message 195 by PhospholipidGen, posted 05-19-2003 01:56 PM [This message has been edited by Adminnemooseus, 07-09-2003]

Phospho writes: As far as that goes, to be honest, I see evolutionary theorists (not those who claim to be evolutionists from the "work" theorists do) as people who have purposefully done one of two things. They either pruned their papers to highlight certain things that gave credence to their pet theory, or they honestly assumed certain things in order to procede with their investigations...but then failed to cease assuming those things when the evidence dictated that they were not possibilities. Like any investigation, if there is no peripheral supporting evidence for an assumption, then that assumption is not warranted and most likely not even a possibility. It seems that you view laborers in the field of evolution as inherently dishonest people who latch onto the theory of evolution for philosophical or anti-religious reasons and then adhere to it in spite of the lack of supporting evidence and the presence of falsifying evidence. But people don't dedicate their careers to the pursuit of something they believe false, and such a situation as you describe would result in a host of whistleblowing former evolutionists who could finally bear the duplicity no more. Or it would force you to believe in a massive conspiracy where no scientist every breaks the code of silence about the bankruptcy of evolution. As Crashfrog just explained, evolutionary theory explains the available evidence. It is accepted because of the evidence, not in spite of it. The purpose of any theory is to provide a framework of understanding for natural phenomena, and evolution does this for biology. The explanatory and predictive framework it provides has immense value, and this is why it is accepted nearly universally by scientists. As much as Creationists like to believe otherwise, there is no competing theory to evolution. If you think there is, then try providing alternative scientific explanations for the evidence in Crashfrog's Message 199. --Percy This message is a reply to:Message 200 by PhospholipidGen, posted 05-19-2003 02:20 PM [This message has been edited by Adminnemooseus, 07-09-2003]

"Q"...
quote: I don't remember saying that. What I remember saying is, though a mutation may carry with a beneficial side-effect, it still remains carrying with it the original deleterious affect. You say that this is not a consideration because that means that I must assume purpose, and you see a cosmos without purpose, only chance and natural selection. This is your paradigm, not mine. So then we must get back to what the facts of nature state. i beleive that I have read about a paper describing the results of tampering with the specificity of proteins, and the paper described the fact that certain areas of the protein was not affected by substitutions and the like, for they did not change the protein's conformation. Yet other mutations did have an effect, and every effect that they had on other areas (particularly regarding the pritein's active site) did change the protein. It rendered it useless, or nearly useless, for carrying out its function. I believe that this demonstrates that, contrary to what some think, the entire genome of organisms was not put together by successive mutations over millions of years. Before I can believe this in a logical and cohesive manner, it must first be demonstrated to me. Do you know of any experiments where an entire and unique genome is being put together from nothing? OK, maybe that a bit out there, how about starting from the basic nucleotides, on up to some kind of organism? To date, I have not seen any evidence, aside from pure speculation worded as "matter-of-fact" statements, of the kind of genetic change that evolutionary theory needs to codify itself. In other words, making some kind of specific change in an organism, creating phenotypic novelties which did not exist before the mutation took place. In other words, please give me something besides speculation to show that mutations of any kind could give something that wasn't coded for before...a fin where before there was none, changing that fin into a leg, changing that leg into your right arm, complete with hand, finger and thumb. I just realized something, perhaps I have been targeting the wrong thing. Irregardless of our argument concerning mutations' standing as beneficial or not, really what the question is, is whether they can produce the diversity on this planet that we behold today. All of the arguments to date have been over what mutations ARE, not what they are capable of doing (to a certain point). Resistance does not change an organism from a single celled organism into something else. Neither does a new copy of a gene. So what can? Greetings!

Hi Phospho, I appreciate that you're busy, and I can see that you want to be thorough and not miss any posts, but I doubt this discussion can make much progress if you're always replying to two week old messages. It might work better if you could read forward to the present and then reply to those messages that seem most apropos. Just a suggestion... --Percy This message is a reply to:Message 203 by PhospholipidGen, posted 05-19-2003 02:47 PM [This message has been edited by Adminnemooseus, 07-09-2003]

quote: My point is this, there are truths, reality, facts that cannot be experimentally reproduced in a lab, and then some not even reproducible out in the field. Yet they exist none the less. You believe in wind currents, do you not? Yet they are unpredictable as to their details. Watch your local weather man today, his predictions about the weather tomorrow, and then watch tomorrow when he shows the stats and compare how good he called it. they are hardly ever right, and even when they are close, they never come close to the details (wind speed, etc.) There are forces in this world that cannot be seen by the human eye, just as certain frequencies of sound cannot be heard by the human ear, yet animals can see them, and hear them as well. When a door opens and slams shut repeatedly, seemingly all by itself...when things fly across the room seemingly all by itself...and when apparitions of people appear out of thin air at their will...these are all things that cannot be repeated experimentally, yet they occur. Please don't start with the nonsense, be adults. I have never taken drugs nor was involved with any kind of cult group, yet I have seen these things, and more. Just because you have never had the experience does not mean that these things did not, nor could not take place. And no, I do not use these things as a spring board for my arguments, they are all from a scientific point of view. As Mayr has stated, the arguments are never concerning the facts of science, but the interpretations of those facts of science. Greetings!

quote: Negative, I do not believe that this is the case. I wish I had access to my papers right now, but I do remember reading somewhere that the genetic capabilities of just one man and one woman coming together, allelically speaking, is staggering. And yes, I beleive that the human population has a whole lot of variational capabilities.
quote: This was my argument before. Darwinism is dead, and the synthetic theory (Neo-Darwinism) came about because certain key theorists couldn't stand to lose their pet theory. The genetic mechanisms you refer to are the very ones we argue here today. You say that you believe that they are capable of producing a human from a single-celled organism, and I say that this belief is unsubstantiated by the facts. The facts demonstrate that you can change an organism, you can put a leg where an antennae is supposed to be. You can change the genetics of a fly and make its halters full fledged wings, but none of this gave the organism something novel or new, it just changed the area from where it is suppose to be to where it was not suppose to be. This is change, not evolution. When you can produce wings for a horse, or for any other non-flying organism, then you will have demonstrated that evolution is a possibility. Until then, you have no clear-cut evidence, which is why theorists play these word-definition-games. I have already posted about population genetics, they mean nothing to evolution. Greetings!

Phospho writes: What I remember saying is, though a mutation may carry with a beneficial side-effect, it still remains carrying with it the original deleterious affect. This is pretty much what Crashfrog means by word games. If a mutation permits an organism to produce more progeny in the existing environment than an unmutated organism, then that mutation is beneficial. Your hairsplitting about "side-effects" and "deleterious effects" is mere word games. The mutation is beneficial if it provides a reproductive advantage, and surviving long enough to reproduce is a pretty big part of this. A mutation that causes an organism's descendents to be a larger proportion of the population some generations down the road must obviously be a beneficial mutation. It's really as simple as that. i beleive that I have read about a paper describing the results of tampering with the specificity of proteins, and the paper described the fact that certain areas of the protein was not affected by substitutions and the like, for they did not change the protein's conformation. Yet other mutations did have an effect, and every effect that they had on other areas (particularly regarding the pritein's active site) did change the protein. It rendered it useless, or nearly useless, for carrying out its function. I believe that this demonstrates that, contrary to what some think, the entire genome of organisms was not put together by successive mutations over millions of years. It of course makes no sense to generalize from these examples that all mutations have no effect or only deleterious effects. It's probably been said many times now that most mutations have no effect or are harmful. But some mutations are beneficial. Do you know of any experiments where an entire and unique genome is being put together from nothing? OK, maybe that a bit out there, how about starting from the basic nucleotides, on up to some kind of organism? These are interesting questions, but off-topic. This thread is about mutations, not about abiogenesis. To date, I have not seen any evidence, aside from pure speculation worded as "matter-of-fact" statements, of the kind of genetic change that evolutionary theory needs to codify itself. In other words, making some kind of specific change in an organism, creating phenotypic novelties which did not exist before the mutation took place. You've seen the evidence, you're just still in denial. The ball for the discussion about specific beneficial mutations is in your court again. See Message 180. --Percy This message is a reply to:Message 203 by PhospholipidGen, posted 05-19-2003 02:47 PM [This message has been edited by Adminnemooseus, 07-09-2003]

Re: Evidence
quote: No, they wouldn't. Where do you come up with that illogical conclusion? And, yes, supernatural entities can not only be inferred from their actions, they at times can be witnessed in the act. Whether you can see them or not at that moment is another story.
quote: First off, Frog, just because you have never experienced them doesn't mean that they don't exist. If you choose to live your life by what you can and cannot see, you will never mature. Secondly, plenty of people have gathered evidence of supernatural activity. Whether you choose to believe it or not is another story, but in the end, reality will always win. Enough of this. I would like to start another thread, but as you can see, I have a difficult enough of a time just trying to keep up with this one. Greetings!

quote: And this is an argument with little intelligence behind it. I have seen it on every board that I have ever posted on and it is nothing more than another semantic word-game. Purpose is most definitely connected by function, only evolutionists deny this.
quote: I was not using this as an argument. A point, but not an argument. And there is only one thing wrong with your ill thought out, regurgitated rebuttal, as with all that use this ridiculous charade of an argument. You totally ignore the fact of the origin of the so-called "scaffolding", and this destorys your whole story.
quote: Again, not that I am going off topic here, but...if you know what you are doing, this is not a problem................
quote: You make all the same mistakes. Now you are advocating conscience into evolutionary theory. You are now making evolutionary theory a theory of metaphysical advancement. Please, make up your mind.
quote: More "just-so" story telling. Unlike you, I need evidence that this is possible. I will not just take your, or anyone else's word for it, because that is how this whole mess got started anyway. "Darwin said it...it sounds like it would work...it must be real!" Darwin never produced any hard evidence, which is why Darwinism failed. Neo-Darwinism never produced any hard evidence, but was born out of certain assumptions before they could even be verified as being based upon factual information. "Genitals just evolved to match" doesn't tell me anything scientific. That is your opinion made in a "matter-of-fact" statement. You are following in the illegitimate shoes of your evolutionary forefathers. Greetings!

maverick,
quote: Not sure what your getting at. I'm making two points, the first is that a chromosome pair can recombine & produce a chromosome that is different to the original two, given that this is heritable, it meets most definitions of mutation I've seen. Given that you accept that chiasma can occur within genes (I think), then potentially, at least, new genotypes can arise via recombination, as well as new phenotypes. Consider a gene pair that has a chiasma in the middle of it (where x is the chiasma.....) ATGCATGC X CGTACGTA AGGCATGC X CGGACGTA gives.... ATGCATGC X CGGACGTA AGGCATGC X CGTACGTA These genes may very well be unique, therefore change the genotype, & possibly the phenotype too. Now, I'm whistling in the wind a bit, & accept I can't support this, except theoretically. I can't find anywhere that says crossover doesn't occur in the middle of genes, but then I know that crossover favours high concentrations of G or C (if my memory serves me), so it seems plausible that genes may selectively avoid having these high levels of the specific nucleotides (which I can't support either), resulting in chiasma avoiding the genes themselves & "targetting" some rubbish sequence. I doubt the chiasma are that exact in getting exactly the right nucleotides in both chromosomes, but the principle stands. One chromosome could have a large gene, the other a small one (almost certainly deleterious), but it still would introduce a new genotype & phenotype, even if its only property is to be lethal.
quote: Agreed, but I never said it could. If mutation is, & I'll use Percies definition, "a heritable change of genetic material", then recombination is a mutation. It doesn't matter if recombination produces new geno/phenotypes, or not, it is a mutation. Secondly, I am proposing the possibility that recombination does produce new coding sequences when the chiasma occurs slap bang in the middle of a gene. Anyone? Mark ------------------Occam's razor is not for shaving with. |
