Quote: Then perhaps ID advocates should stop promoting it since there are NO facts backing it. Define facts and show me how the amount of "facts" supporting evolution amount to more than the "facts" of ID. I'm betting that the "facts" that support evolution contain many "many missing details mak[ing] it unlikely to be true" as I stated above. I keep hearing about "facts" but noone is actually putting any facts up for review on the evolutionary side of the argument. We've actually discussed some ID "facts" but nothing from the evolution side has been detailed enough to be any use. And I stick with my previous statement that neither is science going by the list of requirements I posted before and so neither should be taught in public schools. |

I am not supporting evolution, just making a rebute. Courtesy of the dictionary: Quote:
God( which everyone knows ID is based on), has never been demonstrated to exist or has ever been documented by an observing party. |

I'll accept that God has not been demonstrated to exist. But remember that God has not been demonstrated to not exist either so this fact (or lack thereof) does not deal a blow to ID. Under the definition you give, evolution is not a fact. Unfortunately the term evolution is used so loosely that they can say it is a fact (natural selection + mutations = change over time = evolution) then switch what they mean by "evolution" moving it into the realm of macroevolution which is not demonstrable and has been shown to be mathematically impossible. |

Quote: The eye is an example of irreducible complexity. This means that if you remove any part from the eye, it becomes useless so that an eye could only evolve if all its parts evolved simultaneously - the chance of which is zero. The usefulness, or lack thereof, does not really determine whether something will be passed on. What decides, is the ability of the organism to survive and propogate with the change. Remember, evolution doesn't strive for "the best".. it goes for "good enough". Playing devil's advocate and assuming the eye couldn't work without all of its properties, what's to say the different components of the eye "evolved" independantly, merely remaining dormant until they all got together at the same time and made a functional eye, at which time the creature was able to start making use of it? Or perhaps, some of the eyes' components were used elsewhere, until they changed function and became the eye. As I see it, Irreducible Complexity would only come into play when a good portion of the components would be a fatal without the rest of the components. And even then, asuming the non-fatal components weren't in place first. -- |

Quote: The real core of the argument is there exists no purely evolutionary mechanism which can account for the progressive steps that could possibly lead to the complex structure of the eye from a simpler form. This simply has not been shown to be possible in the purely evolutionary naturalistic setting. No? Or are you simply unaware of them? It goed something like this: A mutation generates a strain of creatures that has a patch of photosensitive cells. This gives them an edge over their blind cousins and they are selected over them for survival. Now some of these newly sighted organisms will have larger patches of photoactive cells or a larger cluster of nerve cells dedicated to sending and processing that information. At some point, it turns out that it is advantageous to have the photosensitive cells receded to prevent them from damage upon impact or during combat. Amazingly enough, it also turns out to be profitable to have them sitting in a cavity with a pinhole on the outside because the picture becomes sharper. Having a transparent layer of cells that can form a lens is an obvious other step that can be taken prior to this one (and probably should be), but we don't have to take it here since we know of creatures that don't have lenses and the principle has been demonstrated. Either way, it's possible to deduce from other hints and observations that a system has evolved rather than been designed. I'll just cite Dawkin's The Blind Watchmaker or The Ancestors Tale in case you want to read about them. *) Is this same line of reasoning fruitful for those preexisting patterns from which we build the eye? This is an area of active research and it boils down to understaning the complexities of multi-cellular organisms and the ways in which cells can specialised and be build up of bacteria. There've been some pretty astonishing experiments, see The Ancestors Tale and references therein. Quote: There, in beautiful C++ we have the evolution of the eye. I personally don't find the analogy helpful at all. Maybe because I'm not a computer scientist. Quote: The problem is that I'm leaving out all kinds of stuff. I'm calling all these functions and haven't actually done anything to define them. That's not a problem. You've simply downscaled the complexity and reduced the problem to a set of smaller problems that need to be solved. Quote: If they consist of a single line of code, we might potentially be fine. However, in some cases they are clearly made up of many lines of code.
... which is a hint that you have not reached the bottom line and that they could be reduced further, or at least you should try. Quote: But remember that God has not been demonstrated to not exist either so this fact (or lack thereof) does not deal a blow to ID.
Let's leave the existence or non-existence of god out of this. Obviously, if there is no such entity there is no room for intelligent design, but it's never possible to show through observation that something does not exist because at most you'll be able to say that you didn't see it. EDIT: Quote: what's to say the different components of the eye "evolved" independantly, merely remaining dormant until they all got together at the same time and made a functional eye, at which time the creature was able to start making use of it?
Statistics. If part of an organism has no function, then as far as natural selection is concerned it isn't there. Random mutations will destroy such systems on a surprisingly short timescale. We tend to think of mutations occuring very slowly, but for DNA strands that don't have phenotypic effects that affect the fitness for survival the mutation rate is observed to be much higher. Unless all of these systems would spontaneously come into being in the right shape at the same time things like these are impossible. In the chance of this happening is zero (or mor ecorrectly, infinitesimal to the point where we don't expect it to happen in the lifetime of the universe). |

With computer simulations we can also provide evidence: Quote: The eye of a vertebrate or an octopus looks so complex that it can be difficult to believe it could have evolved by natural selection and it has traditionally been an argument against Darwinism by advocates of creationism. Nilsson and Pelger simulated a model of the eye to find out how difficult its evolution really is. The simulation does not cover the complete evolution of an eye. It takes light-sensitive cells as given and ignores the evolution of advanced perceptual skills (which are more a problem in brain, than eye, evolution). It concentrates on the evolution of eye shape and the lens; this is the problem that Darwin's critics have often pointed to, because they think it requires the simultaneous adjustment of many intricately related parts. Nilsson and Pelger allowed the shape of the model eye to change at random, in steps of no more than 1% change at a time. This fits in with the idea that adaptive evolution proceeds in small gradual stages. The model eye then evolved in the computer, with each new generation formed from the optically superior eyes in the previous generation; changes that made the optics worse were rejected, as selection would reject them in nature. How long did it take? The complete evolution of an eye like that of a vertebrate or octupus took about 2000 steps. Nilsson and Pelger used estimates of heritability and strength of selection to calculate how long the change might take; their answer was about 400,000 generations. Far from being difficult to evolve, the model shows that it is rather easy.

Listen up. Evolution has fossil, genetic, and other evidence to back up the theory. Evolution is one of the most robust theories within the scientific community. Intelligent Design is based on assumptions, mainly that organisms are too complex to be random chance. This is an opinion with no scientific basis. There's no concrete proof that organisms are too complex. Not only that, to say that evolution is random chance shows a clear misunderstanding of the evolutionary theory. Without proof of an "intelligent designer," the hypothesis lacks the evidence it requires to make such a claim. OK, assuming you think that the evolutionary theory doesn't hold up, that doesn't mean intelligent design is right by default. Saying that organisms are too complex to be random chance doesn't mean that intelligent design must be the answer. First you have to proove the existance of this intelligence, which no one has ever done. I said it before and I'll say it again... Evolution is not a random process. ----------------- |

Quote: It irritates me when they teach people in school that people came from apes which came from lower animals when they can't actually scientifically prove it. They give a big picture and the many missing details make it unlikely to be true but we await further research to be sure. In the mean time let's go ahead and tell them it's true. Humans don't come from apes, humans and apes share a common ancestor. There are fossile records that can be used as proof of it, and I'm sure no school will teach you that apes magically become humans. ID has not been proven to be true either, should we take it as a fact? Quote: I'll accept that God has not been demonstrated to exist. But remember that God has not been demonstrated to not exist either so this fact (or lack thereof) does not deal a blow to ID. The fact that we can't demonstrate that a certain point is false does not make that point immediatly true. That kind of thinking is often used when trying to prove religious things, but it doesn't make sense. By that logic, the fact that we have no evidence of god makes ID immediatly wrong. -R |

This is pretty much the highest level of detail ever gone into on the subject that I've seen (comparable to statements made by the experts). The missing details are never shown because they cannot be explained naturalistically. The genetic changes required to go from one step to the next are staggering and no mechanism has actually been demonstrated by which these changes could occur. Experimental evidence in other irreducibly complex systems trying to prove how they can come about naturalistically show the contrary as is shown in this paper. Quote: That's not a problem.

Quote: Evolution has fossil, genetic, and other evidence to back up the theory. Evolution is one of the most robust theories within the scientific community. Where are these fossils? Give me the actual data. Genetics does not support macroevolution and it has been demonstrated that macroevolution could not be possible in purely naturalistic settings in actual experiments.

It seems my memory failed me here. I found this, but it only talks about how evolution cannot explain how life began.

Quote: Humans don't come from apes, humans and apes share a common ancestor. There are fossile records that can be used as proof of it, and I'm sure no school will teach you that apes magically become humans. Again, show me the data.

If you are goes to make statements like this then back them up! Computer simulations can use a model of evolution to show natural selection. It might not be identical, but it shows how very small changes over many generations produce a large scale change. They are an important tool and should not be dismissed so lightly. |

Quote: Then what should they teach? Neither. Origins should not be touched in science class. Quote: So, what facts can you give for and against ID theory? What about evolution theory? There are not facts for either. The evidence is interpreted to support either side based on axioms. Quote: If you are goes to make statements like this then back them up! Have you read this paper yet? Quote: What is the difference between breeding dogs or other animals and macro evolution? Breeding merely sorts and destroys existing information in the genome. It does not add new information. In order for macroevolution to be true, new information has to be introduced and this has never been demonstrated. On the contrary, experiments always show that information is merely shuffled and/or reduced with each successive generation. |

Even if it is an advantage it is still possible for it to be eliminated. Oh, I'm sure that many things that could be realised are not. All that goes into natural selection is that there is an edge that give some better chance of producing more offspring with a similar trait. It's a problem of timescales: the timescale at which a certain change propegates through the gene pool and the timescale at which it gets destroyed by random mutation. If the former is shorter than the latter, you expect the trait to spread. And guess what? You can actually track gene flow through a population and measure these rates. Quote: This ignores the whole problem of how the components got there in the first place. That doesn't matter too much.

Meh, if you already have something like a central nervous system it's not a big leap. Nerve impulses are nerve impulses, after all, so the change is probably minor early on. Humans who are born blind can use their visual cortex to augment their processing of audio signals. Obviously rewiring a nerve cluster to process different types of information isn't a difficult task. Quote: This computer simulation is not remotely realistic. Hey, do you want us to explore the posibilities of a proof-of-concept or not? In other words, do you want ID to be studied with scientific methods or don't you? Quote: Where are these fossils?

Or do you mean that fossils provide clues for evolution? Or do you mean that fossils only show discrete steps in evolution as opposed to a continuum? If the latter is your gripe, I will cite ring species again. Quote: Genetics does not support macroevolution and it has been demonstrated that macroevolution could not be possible in purely naturalistic settings in actual experiments.
Ok, first: define macroevolution, just so we know we're talking about the same thing. Quote: And evolution is based on similar assumptions, mainly that complexity in organisms must have developed by random chance. No, that's not what it's saying. There's nothing random about natural selection. Individual mutations are random, evolution is not. It's chaotic and unpredictable, but that isn't the same as random chance. Quote: This talks about currently known evolutionary mechanisms (excluding natural selection which is covered here) and how they are not sufficient to provide the changes required for macroevolution.

Too bad that page gives no links to original papers (or else I missed them).

Genetics. A fairly fine-grained collection of hominid fossils that are more similar to other apes as you go further back in time. If you want a litterature reference, The Ancestor's Tale devotes its opening chapters to the subject. Quote: The whole topic of origins should just be left out because it is not a scientific study but more a philisophical/religious one. No, questions of the reason of the universe and the meaning of life are outside the scope of science.

I am talking about the discrete steps as opposed to the continuum. I'm still reading the article Richard Phipps pointed out which talks about these things. Again, macroevolution is assumed so the fossil evidence makes way for story-telling to fill in all the holes. Also, ring species is talking about natural selection. Quote:
Ok, first: define macroevolution, just so we know we're talking about the same thing. The key word is "observed." Macroevolution has not been observed nor can be.

The problem is that evolutionary scenarios have to be painted. They are not observed in the actual evidence but merely assumed. This assumption leads to the story-telling. Quote: The properties and responses of biological systems are not because they can be studied by scientific means: asking precise empirical questions, doing experiments, observing, forming a model, making a theory, making predictions, asking new questions, doing new experiments,... etc. Agreed. But what is actually observed, and what is merely story-telling is never differentiated. The story-telling part needs to go bye-bye. Quote: For those of you who argue for ID from a religious background or because the bible says otherwise, you do realise that there are bible passages that specifically state that the Earth stands still? This is not the issue. Discrediting the Bible does nothing to the actual arguments that are taking place here. |

Quote: Story telling? Do you purposely ignore all scientific work and fossil evidence that has been uncovered? Well, since I have not been shown this scientific work and fossil evidence yet I can still say that it is mere story-telling. So far I have not been shown anything that answers to my claim. All works I have researched so far provide no actual scientific evidence. I'll review any works that I have access to. The one RP linked to is quite long but I'm in the process of reading it. I'm on section 3.1 right now and so far no real evidence has been displayed. Quote: It constantly is through the fossil record, unlike ID. Again, show me. Quote: Excuse me if I ask for a refereed paper published in a scientific journal rather than a link from a page that has as a headline `Upholding the authority of the Bible from the Very First Verse.' This is an appeal to authority. You discount the validity of the arguments simply because of their source. If what that page says can be demonstrated to be false then you can toss it out. |

Last post before I'm off to other things than my computer, so I'll make it a short one. Quote: How does this say anything about macroevolution?
It doesn't. It was a response to `this severely limits the ability of a trait to stick because if it is not a clear-cut advantage random changes in the next generations are highly likely to prune it out'. Which also doesn't talk about macroevolution because that, by definition of the term, does not happen between two generations. Oh, aside from mutation - you don't need big mutations for natural selection to work. Variations such as already exist on the level of individuals is enough for selection to work (as has been observed in the Galapagos Finch). Quote: You're still not saying anything.
I'm saying that `you're not saying how they got there' is no rebuttal to `eyes evolved from previously existing components'. Sure, you decompose the problem in smaller problems which raise new questions, but what's the problem in that? Quote: And by macroevolution I am talking about the concept that new systems and structures can be added over time to organisms to make less complex organisms become more complex organisms. Such as single celled organisms forming a conglamoration that becomes a multi-cellular organism? Or... what? Quote: While I have not read the book I suspect that the hominid fossils converging with apes further back in time is merely story-telling and there are no actual fossils that show this. If you haven't read the book, don't make assumptions on how it's written. Actually, most of the evidence discussed in the book is based on genetic studies (`molecular evidence') rather than fossils. Quote: But what is actually observed, and what is merely story-telling is never differentiated.
I'm sorry, but I have to ask this: are you familiar with how science works? In a scientific paper the experimental data is always discussed seperately from the conclusions that are drawn from them (and if they're not, then the referee had better reject the paper). (I neglected to comment on this above): Quote: This is pretty much the highest level of detail ever gone into on the subject that I've seen (comparable to statements made by the experts). The missing details are never shown because they cannot be explained naturalistically. I'm an amateur and an expert would undoubtedly do better, but what steps would you like to have spelled out? To me, I made it quite clear and explicit how those steps I did not resolve would be resolved. Quote: Discrediting the Bible does nothing to the actual arguments that are taking place here. My point was not to discredit the bible, but to set the stage for the parabel that leads up to the question I asked at the end: Quote: is your scepticism founded by reason and observation or by religious preconceptions on what the truth should be like?

And since there are always ever-smaller problems to solve, when something doesn't fit with evolution they don't begin doubting evolution but simply appeal that future discoveries will prove them right. Quote: I'm an amateur and an expert would undoubtedly do better, but what steps would you like to have spelled out? To me, I made it quite clear and explicit how those steps I did not resolve would be resolved.
Quote: A mutation generates a strain of creatures that has a patch of photosensitive cells. This gives them an edge over their blind cousins and they are selected over them for survival. How does a mutation generate a new type of cell such as a patch of photosensitive cells? Quote: Now some of these newly sighted organisms will have larger patches of photoactive cells or a larger cluster of nerve cells dedicated to sending and processing that information. If the nervous system is already in place how does it develop the ability to process the information from the photoactive cells? Quote: At some point, it turns out that it is advantageous to have the photosensitive cells receded to prevent them from damage upon impact or during combat. Where did the information come from that tells the photosensitive cells to recede? Quote: Amazingly enough, it also turns out to be profitable to have them sitting in a cavity with a pinhole on the outside because the picture becomes sharper. This assumes that the nervous system simultaneously develops the ability to interpret what this picture means. |

Todd Cope said: but simply to separate real science from fantasy. And ID is so called "real science"? Wheres your evidence? Todd Cope said: Origins should not be touched in science class. Because its to hot of an issue? Thats hardly a reason to stop investigating. Where would we be if the "curch" had actually succeded in keeping various scientists quiet? Todd Cope said: You're still not saying anything. The pot calling the kettle black. You have yet to show any edvidece for your claims, besides that "The universe is too complex for it to have happened without help, so it MUST have had help". What is "too complex"? Todd Cope said: Macroevolution has not been observed nor can be. In your oppinion maybe. You seem to be totally ignoring several hundred years worth of scientific study. Todd Cope said: This is not the issue. Discrediting the Bible does nothing to the actual arguments that are taking place here. But then its the only "source" of "information" creationists can claim. Todd Cope said: since I have not been shown this scientific work and fossil evidence yet I can still say that it is mere story-telling. Let me see if I understood that. "I have not seen the edvidence, so it must be incorrect.". Sounds fishy. Todd Cope said: Again, show me. You first! You may not belive it, but I'm of the oppinion that it all had to have started somewhere. We can go back to say, the Big Bang, but where did that come from, etc. Yet no quantifiable edvidence has ever been put forward for creationism (as in, God crated man, etc). I'd absolutely LOVE it if someone could. edit: Todd Cope said: If one of the students is a Christian does he have to hear evolutionary propaganda? Quantifiable edvidece is the term I think you're looking for. Todd Cope said: Where did the information come from that tells the photosensitive cells to recede? Random mutations. Remember? if a mutation helps the organism survive, it gets passed on. Simple concept actually. Quote: How does this lead to a finch becoming some other different kind of animal in the future? Already existing information is being selected from. No new information is added. External stimuli. All organisms are constantly changing to fit thier environment (including the other organisms arround them). If one changes, so must the other, adnausium. Also, large disasters are known to speed things up. Like a volcanoe eruption, or a meteroite hit, etc. -- |
