The code (information) is in the arrangement of that matter (the particular and complex arrangement of those base pairs). <br />If you see your name written in the sky, you know that really is just smoke vapor, but it's the way in which it is arranged that lets you know that an intelligence (a mind) is behind it.<br /><br />No one has ever seen, nor will they ever see a code (information) spontaneously generate. You wouldn't believe that your name spontaneously generated in the sky, and neither can a gene sequence which provides specific instructions for making a protein spontaneously generate.

I conceded earlier that evolution is a fact...Larry,<br />I conceded earlier that evolution is a fact. Microevolution happens. Like Dr. Meyer, however, I object to the idea that evolution can be used to explain the long-term history of life (macroevolution). Every day we are discovering new and complex cellular mechanisms. As I stated earlier, there are many cellular mechanisms which we still do not understand. There is no way that you will ever convince me that these interdependent, complex mechanisms came about by random mutations and natural selection.<br /><br />I have raised many issues which you have not answered. I'm not sure why you chose not to answer them, but I do not have the delusion that I will convince you with my arguments and objections. Yesterday, I noticed your article in a google bookmark I saved among 15 other pages. I was researching a genetic SNP in one of my patients when I came across your article. I'm not sure why I felt the need to comment on your article. Normally I don't get sidetracked. Perhaps it was in some small way to challenge my own beliefs and make sure that they are still strong and valid. I pray that something I said at least challenges you to consider your world view. At the age of 15 my world view was challenged. I told my parents that I no longer believed in God and I was now an atheist. It broke my parents heart. My quest for answers to the big questions of origin, meaning, morality and destiny has led me back to a creator with infinite intelligence. I consider all other explanations inadequate.<br /><br />As far a common descent goes, I agree with Behe that it really doesn't explain very much. It doesn't say where the ancestor came from, and it doesn't say how the descendant changed from the ancestor. It certainly doesn't say how we go from a very plain ancestor to one with complex and irreducible systems.<br /><br />I believe that while we disagree, It has been good for both of us to interact on your blog and I appreciate your time. For me, time is in short supply, and I have to get back to the work at hand.<br />I will subscribe to your blog, and who knows, I might chime in again.<br /><br />My offer for Mere Christianity still stands.<br /><br />DavidAnonymoushttps://www.blogger.com/profile/12070833188888166338noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-66433903410248873842020-02-15T12:26:32.291-05:002020-02-15T12:26:32.291-05:00@David Sanders,
Please try to focus on the issues...@David Sanders,<br /><br />Please try to focus on the issues you raised. You objected to my claim that evolution is a fact and to my claim that the evidence for common descent is overwhelming. <br /><br />You mentioned four people in support of your objection. I pointed out that two of them (Collins and Behe) agree that evolution is a fact and that common descent is the correct interpretation of the evidence. <br /><br />The other two are John Lennox and Stephen Meyer. Lennox is identified as a mathematician, a philosopher of science, and a Christian apologist on Wikipedia. I'm not familiar with his writings but I have watched a few videos. They don't tell me much about his understanding of biology.<br /><br /><a href="https://sandwalk.blogspot.com/2015/03/are-gods-delusion.html" rel="nofollow">Are gods a delusion?</a><br /><br />I know a lot about Stephen Meyer and I consider him a friend even though we disagree about everything. He has a Ph.D. in the philosophy of science and he has witten several books about evolution. Stephen agrees that evolution, as defined above, is a fact. He objects to the idea that it can be used to explain the long-term history of life (macroevolution) without the intervention of some outside intelligent agency. His views on common descent are ambiguous as evidenced by his testimony in Kansas in 2005.<br /><br /><i>Q. Do you accept the general principle of common descent that all life is biologically related back to the beginning of life, yes or no?<br /><br />A. I won't answer that question as a yes or no. I accept the idea of limited common descent. I am skeptical about universal common descent. I do not take it as a principle; it is a theory. And I think the evidence supporting the theory of universal common descent is weak.</i><br /><br />He frequently uses evidence of common descent to bolster his arguments against common descent. This is very confusing.<br /><br />What's certain, is that his knowledge of areas that I know about leaves a lot to be desired.<br /><br /><a href="https://sandwalk.blogspot.com/2017/06/stephen-meyer-predicts-theres-no-junk.html" rel="nofollow">Stephen Meyer "predicts" there's no junk DNA</a><br /><a href="https://sandwalk.blogspot.com/2015/11/molecular-evidence-supports-evolution.html" rel="nofollow">Molecular evidence supports the evolution of the major animal phyla</a> <br /> Larry Moranhttps://www.blogger.com/profile/05756598746605455848noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-88955704380840234912020-02-14T21:01:28.709-05:002020-02-14T21:01:28.709-05:00@Unknown:

It just says that there was an ancestor that had some features and now in the present a descendant has those features. But, it doesn't say where the ancestor came from, and it doesn't say how the descendant changed from the ancestor. So, just saying common descent doesn't explain the most important part of how we get from a more plain ancestor to one with a lot of new and interesting features such as wings or eyes. Darwin's mechanism of random mutation and selection was the key to try to try to explain where these new and sophisticated features come from, and I like to keep my focus on that because it's been my experience that Darwinists will be happy to talk all day or argue all day with you about common descent, but they run like vampires that see a clove of garlic when you ask them to explain: how did random selection and selection make an eyeball or make a flagellum or so on. So I like to keep it focused there. I admit that my colleagues in the intelligent design movement do raise good objections against common descent, but I'm willing to grant it for the sake of argument and focus on the mechanism of evolution."<br /><br />Wow, that's a long quote, but I think it makes it very clear that Behe is not in your camp, and using his quote out of context to make your point is a little misleading. It also brings to light the fact that you are doing exactly what you are accusing me of by misrepresenting the views of Behe and Collins. It also clearly shows that Behe is right when he says you want to shift the argument toward common descent and away from the mechanism of evolution. You accuse me of trying to move the goalpost by changing the topic to origin of life (Collins sees God in DNA) and the complexity of the cell (Behe's irreducible complexity argument).<br /><br />Again you accuse me of being irrational, because I misrepresent the views of Behe and Collins, but according to the above stated facts and quotes, it is you who is misrepresenting them by taking quotes out of context and acting like they are in your camp when it is quite clear that they are not. These are "good minds" as I said who oppose your view of evolution and so are the other two doctors that I suggested, but you said nothing about them. You clearly said there were no good minds on the creation side.<br /><br />You also never answered what I said earlier:<br />Again, consider your derogatory language when addressing me or any other dissenting opinion of evolution, and ask yourself why. Is it true that only the religious, anti-science, silly, nit-picking, illogical people would not find evolution to be a "fact"? Are there really no "good" or "brilliant" minds on the other side as you say.<br /><br />Francis Collins was converted when he read Mere Christianity by C.S. Lewis. Would you commit to read it if I send it to you? It's clear that Collins was Changed by something, and I believe that he is still changing. Behe was changed, and is still changing his ideas. Perhaps you could change too Larry.<br /><br />In conclusion, I want it to be clear that I am not trying to remain anonymous or unknown as these posts might imply, I just don't see a way on the post to comment any other way. Also, I am not your enemy Larry. I am quite sure that you would think much less of me if I had a view on origins and and the nature of reality and never stepped up to defend my view.<br /><br />David Sanders <br /><br />Anonymoushttps://www.blogger.com/profile/12070833188888166338noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-73148844086745564482020-02-14T18:39:15.033-05:002020-02-14T18:39:15.033-05:00I had to break this into two posts due to length, ...I had to break this into two posts due to length, sorry.<br />Interesting that you didn't mention the other two doctors that I mentioned. Do you not think that they are "good" minds. Also Francis Collins does not believe in undirected evolution but evolutionary creation. Here's an exact quote from him: "I see this as answering the question of how God did it."<br /><br />Why have you never answered my question: Where is the overwhelming evidence that "Humans and chimpanzees evolved from a common ancestor that existed roughly six million years ago"? Why are there no transitional forms in the fossil record? Did you actually read my reply, or just cherry pick your argument.<br /><br />You said: "There are not "good minds" on both sides of this issue and there certainly aren't "brilliant minds" on the creationist side who deny the facts that I just described."<br /><br />I mentioned 4 names you mentioned 2. Francis Collins certainly cannot be used for your side because he believes in Evolutionary Creationism. Here's a quote from BioLogos:<br /><br />"But while we accept the scientific evidence for evolution, BioLogos emphatically rejects Evolutionism, the atheistic worldview that so often accompanies the acceptance of biological evolution in public discussion. Evolutionism is a kind of scientism, which holds that all of reality can in principle be explained by science. In contrast, BioLogos believes that science is limited to explaining the natural world, and that supernatural events like miracles are part of reality too.<br /><br />Here's a "good mind" that says what you believe is scientism. Do you really want to use him to make your argument. Francis Collins saw the information contained in DNA and knew that information comes from a mind. He could no longer believe in matter plus time plus chance equals DNA.<br /><br />It is also unfortunate that you used Michael Behe for your argument. If you read his books, you should know that he is part of the intelligent design movement and rejects the idea of random variation and natural selection espoused in Darwinian evolution as the sole driving force and instead proposes intelligent design. Here's a quote from Behe:<br /><br />"The theory of undirected evolution is already dead, but the work of science continues."<br /><br />Here's a quote from Behe's website:<br /><br />"In his career he has authored over 40 technical papers and two books, Darwin’s Black Box: The Biochemical Challenge to Evolution and The Edge of Evolution: The Search for the Limits of Darwinism, which argue that living system at the molecular level are best explained as being the result of deliberate intelligent design. Most recently, in Darwin Devolves, Behe advances his argument, presenting new research that offers a startling reconsideration of how Darwin’s mechanism works, weakening the theory’s validity even more."<br /><br />It doesn't sound like he supports your view of evolution. In fact, you chose to focus on common descent in your Behe argument which is exactly what he said you would do in this video:<br /><br />https://www.youtube.com/watch?time_continue=13&v=zvS7t-Buwik&feature=emb_logoAnonymoushttps://www.blogger.com/profile/12070833188888166338noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-12765311418084514822020-02-14T14:29:57.421-05:002020-02-14T14:29:57.421-05:00@Unknown

You said, ...<br /><br /><i>"Biologists consider the existence of biological evolution to be a fact." - This statement might be true if you added the word some or many, but certainly not all Biologists including myself would agree with this statement.<br /><br />"It can be demonstrated today and the historical evidence for its occurrence in the past is overwhelming." - And yet you presented no evidence whatsoever, unless you consider the claims of other Evolutionists to evidence when they state over and over that it is a fact.

Here's what Michael Behe says on page 3 of <i>The Edge of Evolution</i>.<br /><br /><i>In the past hundred years science has advanced enormously; what do the results of modern science show? In brief, the evidence for common descent seems compelling. The results of modern DNA sequencing experiments, undreamed of by nineteenth-century scientists like Charles Darwin, show that some distantly related organisms share apparently arbitrary features of their genes that seem to have no explanation other than that they were inherited from a distant common ancestor.</i><br /><br />Since you must have read Michael Behe's book, do you agree with him that "... the evidence of common descent seems compelling" and that evolution is the best explanation?

Both of these men agree that evolution is a fact and both of them accept common descent. <br /><br />Here's what Francis Collins says in <i>Language of God</i> on page 141.<br /><br /><i>Evolution: A Theory or a Fact?<br /><br />The examples reported here from the study of genomes, plus others that could fill hundreds of books of this length, provide the kind of molecular support for a theory of evolution that has convinced virtually all working biologists that Darwin's framework of variation and natural selection is unquestionably correct. In fact, for those like myself working in genetics, it is almost impossible to imagine correlating the vast amounts of data coming forth from the studies of genomes without the foundations of Darwin's theory. As Theodosius Dobzansky, a leading biologist of the twentieth century (and a devout Eastern Orthodox Christian), has said, "Nothing in biology makes sense except in the light of evolution."</i><br /><br />Since you must have read that book, do you agree with Francis Collins that evolution is "unquestionably correct"?

I would certainly agree that micro evolution certainly is a fact, but that could never explain the complexity of the cell. There are complex systems and information in the cell. Information and systems only come from a mind. Where did the first protein come from let alone the first cell with all of its complex machinery? Was it that primordial pool of chemicals that was struck by lightning?<br /><br />Again spouting more evolutionary dogma without any evidence and putting me down in the process does not bolster your case. I'm actually pleasantly surprised that you even allowed my comments. Where is the overwhelming evidence that "Humans and chimpanzees evolved from a common ancestor that existed roughly six million years ago"? Why are there no transitional forms in the fossil record?<br /><br />So you don't consider Dr. Stephen Meyer, Dr. John Lennox, Dr. Francis Collins or Dr. Michael Behe "good minds". I would say these guys are brilliant. Have you ever read "Signature in the Cell" or "The Language of God"?<br /><br />I don't think that it is likely that any argument I give will ever convince you, although I wish that were not true. If you look at life's big questions of origin, meaning, morality and destiny, and you start off believing in Darwinian evolution as your origin, you will certainly have a different outlook on the other three. <br /><br />Again, consider your derogatory language when addressing me or any other dissenting opinion of evolution, and ask yourself why. Is it true that only the religious, anti-science, silly, nit-picking, illogical people would not find evolution to be a "fact"?

Here's a glaring example:<br /><br />"Biologists consider the existence of biological evolution to be a fact." - This statement might be true if you added the word some or many, but certainly not all Biologists including myself would agree with this statement. <br /><br />"It can be demonstrated today and the historical evidence for its occurrence in the past is overwhelming." - And yet you presented no evidence whatsoever, unless you consider the claims of other Evolutionists to evidence when they state over and over that it is a fact. Making a claim and stating it over and over does not make it a fact.<br /><br />You act as if it is not OK for us to question the "fact" of evolution. You deride religious people for not buying your "fact" of evolution, but people can be both religious and scientific and the same time. Here are your words:<br /><br />There are many people who reject evolution for religious reasons...These people will not be convinced of the "facthood" of (macro)evolution by any logical argument and it is a waste of time to make the attempt.<br /><br />Essentially what you are saying is that any religious person who doesn't buy the absolute "fact" of evolution is an illogical idiot. You are acting as if no creationist could offer a legitimate debate over this issue, and that it is totally settled. When in fact, there is raging debate going on still today over this issue, and there are good minds on both sides of this issue. Brilliant minds in fact.<br /><br />I myself am constantly working with the cellular mechanisms of blood sugar dysregulation. These mechanisms are so complex, that we still don't understand them to this day. Here's a quote from an article in the UPSALA Journal of Medical Sciences that I recently read:<br /><br />"Despite decades of research, an understanding of how glucagon secretion is regulated remains elusive, and fundamentally different mechanisms continue to be proposed."<br /><br />You are asking me as a person of science to believe as fact that mechanisms so complex that we may never fully understand them, came about by mutations and random chance. As a person of science I can't possibly look at a cell and believe that It came about by random chance. Stating that evolution is a fact over and over again in different ways doesn't make it any more true. What you are asking me to believe as "fact" is that blind and purposeless material process is our true creator and that "God" is a product of my primitive human imagination.<br /><br />I'm sorry sir, but your "fact" stretches credulity to the point of breaking. And the fact is, that many good scientists would certainly agree with me, and they don't even have to be "Religious" to do so. Your article is misleading when you imply that only the religious, anti-science, silly, nit-picking, illogical people would not find evolution to be a "fact". All of these derogatory terms for people who do not believe as you do are in your article. <br /><br />We should be able to have genuine debate and discourse without this name-calling and vitriol.Anonymoushttps://www.blogger.com/profile/12070833188888166338noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-87569584967218669722013-01-12T17:47:14.489-05:002013-01-12T17:47:14.489-05:00I use the term "The Theory of Evolution"...I use the term "The Theory of Evolution", but while I don't see a problem with it at all, I also do not have a problem with using "evolutionary theory" instead. Where I personally think the problem lies is in the usage of the word "evolution" by itself to refer to the scientific theory. I think that's very problematic, including making it easier for anti-science people to radically cloud the whole subject. We don't do this with other parts of science. For example, no one would ever refer to gravitational theory as "gravity". That would just be very confusing, wouldn't it? So why do we refer to evolutionary theory or The Theory of Evolution as evolution? We have to stop doing that, in my opinion. The word "evolution" by itself should primarily and perhaps only be used to refer to the idea that life forms change over time, usually into more advanced forms. That idea is a publically observable occurrence (a fact), and should always be treated as such, without using all the ridiculous language creationists want us to use in order to confuse everyone and make it seem like there is some kind of legitimate debate with regard to whether evolution happens or not. There isn't, and we've got to stop helping the anti-science people with their agenda.

To be perfectly honest, I'm not sure when something becomes eligible to be a Law with a big L. In hindsight, I think I was really meaning "law of evolution" with a small L, as in " law of biogenesis" - an observation that has never been falsified and is accepted as fact.

I...I learned a lot when I read the earlier version. I don't agree with everything and as a physicist I would press more on the ubiquity of natural processes, but that is small quibbles.<br /><br />@ Anonymous:<br /><br />"I have always understood "facts" to be those things that can be directly observed, while "theories" are explanations of those observations."<br /><br />But nothing is "directly observed" nor do we have "explanations"!<br /><br />- Already Newton realized in spite of having realism we can only use causality to probe nature, we can only learn from a systems reactions on our actions.<br /><br />Quantum mechanics revealed further that it is meaningless to entertain the notion of properties between states, that observation can only tell a subset of reactions (observables), and that it changes the system we observe.<br /><br />Finally special relativity took away the ability to do immediate observations "here" and "now", we have only access to the lightcone of probe particles so see "there" and "when".<br /><br />There are, as in the case of observable facts vs testable theories, a quantitative but no qualitative difference in remoteness (using instruments, using instruments on other planets, using instruments that captures probe particles (light) from the early universe, et cetera).<br /><br />- Theories are predictive, so we can test them for validity. But gravity doesn't tell you the exact pathway (as the article notes), so doesn't provide a minute explanation for your apple fall. You can't get from a statistical description of apple trees & winds to a prediction of an individual apples fall.<br /><br />On the other hand with the new standard cosmology, general relativity has been tested to the extreme limits of our observable universe by observation of more or less "direct" nature.<br /><br />I would say that the observation of processes are facts for everyone, and that processes are theories for realists, i.e. for a realist there is a well defined mapping between the process and its validated theory. We know curvature of space-time exists, what we don't know is if curvature changes by particle mediation.<br /><br />@ Larry Moran:<br /><br />"I've tried. It's not possible."<br /><br />What a challenge! Especially since "laws" are falling out of fashion, to be replaced by "universal facts" and "general principles" instead.<br /><br />Not being a biologist, I would have though that Fisher's fundamental theorem of natural selection and Hardy-Weinberg equilibrium ("<a href="http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/H/Hardy_Weinberg.html#When_the_Hardy-Weinberg_Law_Fails_to_Apply" rel="nofollow">Hardy-Weinberg Law</a>") would qualify.<br /><br />But maybe you mean the larger theory. Well, I would think that the observation that "descent by modification" results in phylogenies, trees or bushes (nested sets), would be a law. (I hear that you may need "super-matrix" methods to resolve both vertical and horizontal gene transfer, but it seems doable. Even if not, trees are more common than not.)Torbjörn Larssonhttps://www.blogger.com/profile/13304729731231255545noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-78061747064576270382011-08-18T23:20:37.907-04:002011-08-18T23:20:37.907-04:00Spell check observations, for posterity's sake...Spell check observations, for posterity's sake:<br /><br />1) "In it's place we talk about evolutionary theory [...]"-- the possessive is incorrectly spelt.<br /><br />2) "The sad thing about the Gould [...] conitinue to be relevant today."-- "continue" is incorrectly typed?<br /><br />that is allAlexhttps://www.blogger.com/profile/02590604089043425452noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-74881969531219100482011-08-18T22:02:49.272-04:002011-08-18T22:02:49.272-04:00Very nicely explained.

After all, we have never encountered a life form that has demonstrably not evolved from earlier life. Indeed, we have not encountered an organism that clearly did not evolve from the Last Universal Common Ancestor. I have encountered Creationists who have been a bit obsessed with Laws because they "cannot be broken", and so it might shut them up. (Of course, Laws <i>can</i> be broken and are updated or re-scaled in the light of new data but I suspect that anyone savvy enough to know this would also to be savvy enough to understand what a scientific "theory" really is.<br /><br />Great post, well said.Richard Edwardshttps://www.blogger.com/profile/16115218690707131186noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-47597375395304283152011-08-18T16:24:36.519-04:002011-08-18T16:24:36.519-04:00I have always understood "facts" to be t...I have always understood "facts" to be those things that can be directly observed, while "theories" are explanations of those observations. Thus, "Apples fall to the ground" is a fact, but even today the mechanism is poorly understood, and thus gravity really is "only a theory," and the jury is out on whether it is the curvature of space-time or the exchange of graviton force particles.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-37148773.post-90232187660898675992011-08-18T16:03:15.959-04:002011-08-18T16:03:15.959-04:00@middle.professor,
You are correct when you say t...@middle.professor,<br /><br />You are correct when you say that you read Gould very differently than I do.<br /><br />You are incorrect when you say that I rank fact and theory as part of a hierarchy or probability. Some parts of evolutionary theory are facts—natural selection is a fact. Some parts of the history of life are not much more than speculations. Some facts, such as chimps and humans sharing a common ancestor, are factual even though we don't know how much of a contribution natural selection has made in each lineage (i.e. we don't know the mechanism.)<br /><br>Larry Moranhttps://www.blogger.com/profile/05756598746605455848noreply@blogger.com
