The only statute currently under consideration is one in PA and the Discovery Insitute has recently advised against passing it because they're afraid of the court battle. The ID proponents are switching tactics from forcing the teaching of ID to forcing criticism of evolution.

Similarly, we have the eclipse experiment of 1919. If Einstein's theory of gravitation were bogus, star positions as recorded during the eclipse would be spatially equivalent to their positions recorded prior to the eclipse. But according to Einstein's theory, the mass of our sun would be sufficient to "bend" the light of distant stars as it passed the sun. This theory by its nature gives rise to such a risky prediction. It is therefore attributed as a scientific theory. The severity of the test one can devise for a theory defines its scientific nature.

I understand that Relativity has experiments that prove it. But they are evidence of the theory, not the theory itself. Just as evolution is a theory and need not articulate its evidence when described. However, it can be articulated when we have a debate. My side of the debate is presented here.

Base (building block) sequences change from species to species in the same protein or gene sequences. The change in a particular protein or nucleic acid is a measure of the divergence of those species. The fosil record also shows the divergence of species.
Comparing the evolutionary trees generated from fosil evidence with the tree results gathered from the biochemical analysis of existing species yields compatible results that confirm the correctness of the fosil evidence.
The same results from two very different techniques. When both biochemistry and the fosil record provide the same results for the divergence of existing species, then the need for falsifiablity is satisfied as is the requirement for prediction.

For example, is George Bush the president of the US? (Notwithstanding stolen elections, etc). The probability of this being true is very close to 100%, and the probability of it being false is close to 0%. But, it is never zero. There is a non-zero probability that any arbitrary crazy-ass thing you can think of is true.
The problem, though, is that the above is no way to run a thinking mind in the real world from day to day. You have to make real binary decisions about whether to do something or not do something, and you can't be constantly confused by doubting reality, so most of these probabilities from an epistemological standpoint can just be rounded off to a 0 or a 1 so you can get some actual work done.
Evolution is both a fact and a theory. From a fact perspective, evolution as an explanation for life has a probability so close to 100% that the remainder can just be discarded. From a theory perspective, evolution has tremendous predictive power.
In any case, I think the epistemological underpinnings of science are something that most people don't understand, and the idea that nothing is certain in science can be frightening and confusing (and misleading if used for devious purposes as the IDers do).

However, there are millions of ways that evolutionary theory could have been falsified. JBS Haldane famously gave the example of "fossil rabbits in the Precambrian" (i.e. from before life began on land) -- they don't exist.
The molecular evidence of evolution could have failed to match the fossil evidence from paleontology, but it did not.
The radioactive dates assigned to fossils could have been inconsistent with evidence from geological sediments -- it wasn't.
I could go on, but my point is that it's better to think about real ways that scientists have tested a theory than worry about the abstract concerns of philosophers -- they've spent centuries merely catching up with the practice of science.
by theodicey on Wed Nov 02, 2005 at 11:41:37 PM PDT
There's a problem with saying that there are a million ways to "falsify" evolutionary theory: which of these arises from a risky prediction? To what extent does the Haldane example facilitate corroboration of the theory? If we don't observe fossil rabbits in the PreCambrian period, to what extent do we conclude that we have learned something about the applicability of evolutionary theory? I can't say that we learn absolutely nothing from this case, but its anecdotal form attributes little in the way of meaningful evidence. The proper question to ask is what is the probability that the theory is still true or false in the presence or absence of the observation. Scientists would say that this is therefore not a severe test, and thus it does little to establish evolutionary theory as scientific.
I think most scientists find the work of Popper, Kuhn, Lakatos, Scheffler, Salmon, Hacking, Mayo, etc.. as quite relevant to the practice of science. Kuhn's "Structure of Scientific Revolutions" didn't make the NYTimes 100 most influential books since WWII for nothing. But this is a digression.

IDC makes no such predictions. IDC is consistent with a Young Universe or an old one. It is consistent with Special Creation of Kinds or Baramins, and it is consistent with theistic evolution. It is consistent with common descent and it is consistent separate design. It works with extra-universal aliens or armies of supernatural critters. It works for a universe created lat wednesday, it works for one created 14 BYA.
It is consistent with anything, because a vague, omnipotent designer can do anything. There is no evidence which can falsify that claim. And that's why IDC as it is currently presented is not science and never will be.

Either of those things is fine and, God Bless America, I'm all for that. But not in a SCIENCE class.
What is so difficult to understand about that? Of course, we know the answer: there's nothing difficult to understand about separating church and state (at least not on the level we're talking about re: this ID piffle and evolution and teaching the origin of the species in science classes). No, the concept's pretty easy to grasp -- what the IDers want to do is do away with that separation and tear down that wall between church and state and, in this case, do it in what they think is a clever, sneaky, back door manner.

The question that arises here is to what extent does evolutionary theory actually entail the outcomes or predictions that have been noted. To what extent would we overthrow the theory if an ostensible counter-observation were made? What sort of competing theory is available that is entirely naturalistic that doesn't somehow fall into an evolutionary rubric? I can't imagine a priori what that would resemble.
And notice interestingly that the actual observations made with respect this theory (or any theory for that matter) do not bear witness to its scientific status. A theory can in fact turn out to be grossly false in the minds of scientists but still be wonderfully scientific. It's all about the severity of the testing possible on the basis of that theory. We can attribute this particular quality without stepping foot into the field. Again it doesn't have to turn out to be true to be scientific. That sounds nutty at first but it resonates with scientific inference.
by Malachite on Thu Nov 03, 2005 at 08:02:46 AM PDT
In fact, every naturalistic theory is concerned with change, in particular, describing the mechanisms of change. Some aspects of a natural event are regarded as stable or permanent with regard to that event. It is through observation of the actions and relationships of those stable elements or inferences to their relationships and actions that one arrives at a particular description of that event. Believing that macroevolution lies outside the realms of testable science confuses the relative permanence of some aspects of biology, regarded as permanent for certain purposes, with an absolute metaphysical permanence.
Darwinian macroevolution is indeed a scientific theory. It makes different predictions than other (Lamarkian) evolutionary theories. What I think is funny is that folks think ID is just creationism in "new" clothes or some sort of "new" idea. William Paley elucidated the theory well before Darwin, in fact, Paley was quite revered by Darwin. (Darwin intentionally uses the same form of argument (argument by analogy) as Paley. And ID was defeated even before Paley published his idea by David Hume, who never met a proof for the existence of God he couldn't completely destroy.

Either way it's evolution. The term gets used by creationists so that they're able to admit the evolution for which there is good lab evidence without having to buy the whole origins-of-species sort of evolution.
I refuse to use the word; I don't think it's useful, and it just feeds into their frame.

I would think that in discussions wherein you want to talk about a smaller-scope processes, you could just say "I'm talking about small-scope inference, here," and then just go on and talk and use the word "evolution."
This is not different from the day I saw the phrase "Tax Relief" in a NY Times headline. I thought, shit, we're done, now...
So I bridle when I hear people who know evolution use terms coined (or co-opted) by creationists. Then we're arguing on their terms, and those arguments we cannot win effectively.

So the Intelligent Design emphasis on discrediting Darwin in their discussion demonstrates that they are out of touch with the vital, changing aspects of real science and its treatment evolution as a real theory. Evolutionary scientists are always discussing things like horizontal gene transfer and gene convergence, and models for molecular clocks, and their limitations. They are pointing out the relevance of these topics for modern life, like antibiotic resistance in HIV and rapid evolution of influenza virus through recombination of the 9 smaller RNA genomes within the virus.
By focussing on creation vs. Darwin, they miss the point of 150 years of additional research and a HUGE explosion of genomics information. Those ID people saying molecules are too too fabulous to have happened by accident should wander around in the genomic databases a bit and see the massive code reuse.
Computer folks out there know that you don't just redesign code from scratch every time you want to write a program. You rework old portions- sometimes using something slower and glitchier, in order to get a job done quickly. Molecular evolution is full of similar code reuse, where code replacement would work more efficiently. It is insulting and bogus and reflects limited understanding of new information and predictions. Code reuse is a prediction of natural selection models, not intelligent design.

Even if this were true, it would have no bearing on whether the theory of evolution is scientific -- the falsifiability of the theory of evolution is well established in both the scientific and philosophy of science literature.

The prepublication manuscript of Of Pandas And People (OPAP) was subpoenaed, and all the references in the published book to Intelligent Design were written as Creationism in he manuscript. Quack quack.
A rhetorical trick: in the second edition of OPAP, all references to "evolution" were replaced with "Darwinism" in order to push their frame of a cult of Darwin.

Presuming for the sake of argument "God," either God can do this, or not. If God can do this — which is the implicit claim of the Creationist crowd — then you have to make some theological excuse for why he doesn't. Perhaps our laboratories don't know how to invoke Him effectively? If that's the case, then we should work on how to pray better. But who can teach that? Any Creationist leader who can't even pray effectively enough to get God to generate new examples of complex life from nothing is not the one to teach our scientists how to pray, obviously.
Or maybe we have to allow the excuse of "God could do it but He doesn't want to." So you posit a God who for some reason wants us to believe He can do it, but doesn't want that badly enough to actually cooperate in a laboratory to prove His powers. That's like the child who wants us to believe he's gifted but won't work in school.
There's an historically-recent notion that God doesn't want to be provable by science, since somehow that would undermine the value of faith. That notion only came into vogue with the failure of science to prove God. All of those at the cusp of modern science, from Newton to Descartes and beyond, were firm in their belief that science would prove the existence and nature of God. Faith in proof and faith in God were the same thing.
Well, faith in proof has proved of lasting power; faith in God we can at best make excuses for, as having some psychological value despite the proofs of science demonstrating that the greater part of most religions, taken at all literally, are flat-out false. We can still have religion along with science, but only if religion yeilds to proof. We must return to the faith, at the root of science, that reality, when openly explored and tested, will not deceive us.
To not believe in reality, that is, to believe that reality lies, while the fantasies written up in certain old books — internally contradictory as they are — somehow do not, that's batshit fucking insane at this point in history. We've got a major mental health crisis on our hands. Something like half the population of the most nuclear-armed nation is batshit fucking insane, and even thinks their God might be happier if they just destroyed our planet.
And that's why it's so important they not be enabled to use our schools to recruit youth into their cultish madness.

In any case it's absolutely not true that evolution is unfalsifiable. Every fossil found, every new species identified, every strand of DNA sequenced, and every mutation observed is a test of evolutionary theory. It stands up to every test.
How to falsify it? Find a fossil of a griffon (i.e. a bird/mammal intermediate).
Bang, right there you've falsified a major section of the accepted evolutionary history of vertebrates, because mammals and birds are expected to have come from different branches of early reptiles, and there should be no ancestor which shares characteristics of both.

Heliocentrism was inferred from the phases of Venus, and much later from the aberration of light and, still later, from stellar parallax. Evolution, and common descent, can be inferred independently from multiple sources: biogeography, the fossil record, observed adaptation, the mechanisms of inheritance, the Linnaean nested hierarchy, and the genetic nested hierarchy.
In any case, you didn't claim width of inference, you claimed lack of falsifiability. I have challenged that in a way that I think is valid. I invite you to defend or retract your claim of lack of falsifiability, and then, if you like, move on to the scope of inference.
by eyelessgame on Thu Nov 03, 2005 at 02:05:22 PM PDT
From what I'm reading, there are particular stellar parallax measurements which are expected in a heliocentric solar system. A suite of such measurements defines the orbital motion of the planets over time. Heliocentrism then predicts that such measurements with respect to Mars will show that Mars rotates about the Sun. This is a risky prediction because any statistically significant deviation in the expected measurement/trajectory then retorts the theory. I don't have particular astronomical data handy, but I can imagine that the expected measurement/trajectory in the case of heliocentrism is distinct from that of a system in which the planets do not revolve about the sun (perhaps an understatement). I can see here how to apply error statistics to rule out alternative explanations for any anomalous recordings. This is much like the case of the eclipse of 1919.
In terms of how evolutionary theory is sometimes presented in schools (I should reiterate that I'm not attacking the field but rather the presentation of the theory by some), it is far more difficult to appraise the theory in terms of an anomaly. If I discover a fossil out of expected sequence, is this grounds for overthrowing evolutionary theory? It's not clear in advance what to do with an anomaly, how to treat it, what to do in terms of theory appraisal. Would we really overthrow all of evolutionary theory if we found an anomalous fossil? It's not entirely clear to me that we would. Feel free to help me frame this.
Imagine that stellar parallax measurements show that the planets revolve about Pluto. It's such an odd thing to posit in the first place, but it's so much clearer how to proceed in terms of theory appraisal. It's so much more severe of a test (and thus more clearly falsifiable).
by Malachite on Fri Nov 04, 2005 at 10:46:59 PM PDT
An Albertosaurus with a human femur in its stomach would be more along the lines of evidence since we have a much better grasp on the more recent past so we know that case totally contradicts what we know now.
Another example of disproof would be, say, a mammal giving birth to a reptile, or vice-versa (without scientific intervention in an experiment, of course). That sort of massive change contradicts evolutionary theory, among other things.
by Northwatch on Thu Nov 03, 2005 at 08:56:22 AM PDT
These methodological issues are clearly resolved in terms of error statistics with respect to Einstein's theory of gravitation and the Eclipse of 1919. In the absence of counterexamples, one knows how to appraise the theory. That's because of two key things: 1. the probability P that the theory is true given the evidence E is high. AND 2. the probability P that the theory is false given the counterevidence E' is high.
I guess a much simpler way of expressing this is to say that evolutionary theory (in the grand, expansive sense) might be valid or invalid in the absence of rabbits in the PreCambrian period.
by Malachite on Thu Nov 03, 2005 at 10:56:45 AM PDT

Every current or past living thing we identify will be able to fit into the evolutionary nested hierarchy despite countless trivial examples of potential, imagined living things that would not. See my example of a griffon above.
The relative similarity of the DNA of every living thing will fit into the same nested hierarchy. See, for example, the relative similarities of the six species of ape (bonobo, chimpanzee, gibbon, gorilla, human, orangutan), and how the DNA similarity matches the relative Linnaean hierarchy, the fossil record, and biogeography.
Divergence of DNA, among related species, will show characteristics of having been caused by the known mechanisms of DNA copy errors.
Evidence will continue to be uncovered demonstrating the prior existence of intermediates between related lineages. Countless examples already exist, cf. Ambulocetus, Australopithecus, Archaeopteryx being some of the best known.
These are incredibly risky predictions, given the wide spectrum of possible evidences that we could theoretically discover which would falsify them.
Yet we keep not discovering any such evidence.

I think that there are several different factors at play in your perception of evolution.
I will initially sound backwards like I'm from some swamp land but evolutionary theory as sometimes/often presented is not scientific. And by scientific I don't mean that it doesn't appeal to observation and traditional scientific measures (viz. Thomas Kuhn) because it obviously does. Rather it is presented in a way that offers up no sense of which observations could be made which would represent a falsification of that theory.
First, there is a problem with the quality of science education in general. The problem here is shoddy education, not evolution. A lot of what passes as science education is just a cataloging of dramatic examples presented as received wisdom with little or no contextual backgrounding in why that example is important or where it came from. There is often too much attention given to the final work product (conclusions) of science rather than the processes (evidence and reasoning on the evidence) from which the product emerged. In this sense your criticism is valid, but it is not unique to evolution. It is merely evolution's bad luck to be the only science who's validity is discussed in public these days.
Another problem peculiar to evolution is that it has two distinct aspects that are often mistakenly conflated. This leads to a lot of confusion.
The first aspect is the simplest and most direct: evolution is the change of gene frequencies in populations over time. Call this the process of evolution and it is accessible to test and inspection in labs, the field and elsewhere in the here & now.
The second aspect is the history of life on Earth which is a record of how the process of evolution has worked over time. Reconstructing lineages and understanding the process of evolution are clearly related, but very different things.
The nature and importance of the distinction can be illustrated by considering the fact that I can not find the graves of my ancestors going back more than three generations; I can't unequivocally reconstruct my lineage. Nevertheless, it would be foolish of me to argue from this, as a creationist might, that I had no great great great grand parents simply because I can't find any of their bones. And then to go on and conclude that my existence is therefore somehow miraculous is even sillier. Rather, my knowledge of the process of reproduction leads me to rationally conclude that I did have 32 great3 grand parents even though neither hide nor hair of any them is to be found anywhere on earth today.
Theories are powerful things and supposing that they are weak is probably the single most egregious conceptual blunders creationists make. A well tested and firmly established theory is nearly impervious to discordant evidence. The absence of any evidence of the existence of my deep ancestors is no impediment to me asserting their existence as fact. If somebody cracked the crypt of one of my putative ancestors and found a long dead cat instead of human remains, I wouldn't change my mind. If a large study revealed that 95% of living humans can't locate their great3 grand parents' remains, I still wouldn't change my mind. Creationists are oblivious to this asymmetry in the interplay of data and understanding. They delight in talking about supposed gaps in the fossil record, or the occasional erroneous reconstruction of some lineage or other, but all of that means nearly nothing with respect to the soundness of the theory of evolution.
Even the simple notion of "fact" is a slippery thing and is absolutely dependent on theory. You may think it is a simple, unassailable and concrete fact that some object is 2.3 meters long, but what is a meter? At first it was a defined as a fraction of the circumference of Earth (1/10,000,000th of the meridian from the pole to the equator via Paris) and the definitive standard was later a platinum-iridium alloy bar of said length in the basements of standards bureaus. Nowadays a meter is defined as:
the length of the path travelled by light in vacuum during a time interval of 1/299,792,458 of a second.
And if you can't really test a theory then it's not very scientific (in the sense that most scientists and philosophers of science adopt). If only it were more carefully handled with regard to this in the science classroom

Heck, even the "Law of Conservation of Mass" and the atomic theory of matter which were the most fundamental principles in my branch of science (Chemistry) ended up being wrong. (As proven by atomic bombs, and subatomic particles.)
Every theory provides a model which explains the observed behavior of a system. Confusing this model with reality is common, but it is not correct. Reality doesn't change. Models frequently need to be revised to reflect new data.
Ultimately, science doesn't explore the true nature of the universe, it explains the observed behavior of the universe.
(On the other hand, my dabbling in the philosophy of science is based on personal experience, and discussions and readings from other scientists. I haven't read much from philosophers on the subject.)

It is an observed fact that organisms evolve over time. The theory of natural selection attempts to predict how and why it happens.
You misunderstand - evolution is a fact.
by Ernest T Bass on Thu Nov 03, 2005 at 05:17:47 AM PDT
You could show me millions, or billions, of examples where a theory holds true -- where the observed behavior supports the theory -- and take the theory as proof of the supposition. However, all I have to do is show you one example where your "fact" is not supported and your theory is no longer valid.
This is the current conundrum of particle physics. The theories of Newton, etc. do not hold at the quantim level -- does this make the theory of gravitation invalid? Not necessarily, but the issue is that at the quantim level, the evidence is not there to validate gravitation...hence the search for a universal theory.
My chemistry professor, on the first day of class, started by saying "nothing can be proven...it can only be disproven." That is the true nature of science, to find the "exceptions" to the rule, explain them with new theory, and advance the understanding. If we take things as fact, what is the motivation to continue exploration?
This is the gist of the argument with the religious right -- they take ID as FACT, thus no need to continue the exploration of the origins of life. God is, thus no need to question.
The arrogance on both sides of the discussion is what keeps us in this perpetual debate -- Carl Sagan kept telling us that since we "proved" this or that, that there is no reason to attribute anything in nature to God, thus there is no reason for God.
How many things that were once attributed to God are now explained by science? And how many scientific theories that were held as absolute truths have been found to be false due to the discovery of new evidence to the contrary?
The reality is, none of us can ever KNOW anything, because, lurking way out there in the universe of infinite possibilities, is the exception to the rule.
The Meek Shall Inherit NOTHING

Phenomena can be observed in this reality.
Facts are statements documenting observed phenomena.
Scientific theories explain these facts. To the extent that the theory holds true in the face of new facts, it succeeds.
So your chem prof was being overly simplistic. Facts are proof.
If you re-read this thread, I think you'll see you're talking past somebody who has made a valid point.

When I look at a table-top, I see a solid piece of wood, with a continuous surface. I set a glass down on it, and the glass rests on the surface. I can hear the sound of the glass making contact with the table as I set it down. I can run my hand along the surface of the table, and feel its "solidity."
Yet, if I look at the table "as a chemist," I see that it is almost entirely empty space. The only reason it looks solid is because the electromagnetic radiation which interacts with it has too long of a wavelength to resolve the tiny component pieces. When I try to touch it, the sense of "touch" is provided by overlapping electric fields, summed over the innumerable number of electrons in my hand, and the tabletop. The reason my hand stops is because the force applied by the sum of the electric fields of the electrons (and to a lesser extent protons) in my hand is not exerting a strong enough force to overcome the intermolecular interactions between the component atoms and molecules in the table top.
And if I look at the table "as a physicist," I note that it's not really even made of "matter." It's entirely energy, bound in a state which I percieve as being material, and therefore decide to call matter. But the "bound energy existing as a table" is actually enough energy to destroy the entire planet if it could be completely freed. And amazingly enough, the "surface" of the table doesn't actually exist. Each of the "bound" packets of energy we commonly refer to as "subatomic particles" actually exists throughout the entire extent of the universe, simultaneously. The only reason I consider the table to even have a location is because all of the "particles" in the table are "probably" in approximately the location I sense them at. But the idea of the "surface" of the table is actually two different concepts, neither of which really matches with my intuitive sense of what a surface is. In one case, electromagnetic radiation interacts with the "bound energy taking the form of a table," and is modified and diverted in a manner which suggests that the radiation was changed at a specific location I choose to call "the surface." On the other hand, when I touch the table, I receive a sensation of resistance when my hand reaches a point where it begins to interact with the "table" in a strong enough manner to trigger chemical reactions in some neurons in my finger tips.
On the other hand, I could just inside the Matrix, and everything I think is happening is really the result of a giant virtual reality simulation.
Or perhaps God is taking a personal interest in me, and has been feeding sensations directly to my brain since I was first born, and the world is actually completely different from what I perceive it to be.
Or, maybe there really are subatomic particles, and they are moved around by little tiny elves who can run really fast. They all have little sliderules where they calculate how all the particles should interact, and they move them accordingly. My biggest concern with this theory is that every time we detonate a nuclear bomb, some of the elves are killed, and eventually they might get pissed off and go on strike. We'd really be screwed then.

If it's "all energy," or "all God," then it's nothing. Differentiation is essential to any knowable existence. One of the things the world quite clearly differentiates into is tables.
by wytcld on Thu Nov 03, 2005 at 07:45:45 AM PDT
That's why the "law of conservation of energy" is still a valid scientific theory, but the "law of conservation of mass" has been thrown out the window. (Well, it still applies in an approximate, macroscopic sense, just like Newtonian physics hasn't been completely thrown out)
Energy isn't nothing. Energy is the fundamental "stuff" out of which the entire universe is made. The reason it seems silly is because it's contrary to "common sense," and what our senses tell us. But modern physics has shown us that regardless of what we think reality is like, it is actually quite different.
I'm not trying to say that tables don't exist. I'm just saying that ultimately the differentiation of the world into tables and not-tables is something which is done inside our minds, and is not inherent in the nature of the universe.
There is a standard view of the world based on our perceptions, which we all share. But, if you study modern physics you will learn that this view of the world doesn't work if you try to apply it on a sub-microscopic scale. Our "common sense" ideas about "how the world works", and "what the world is" just doesn't match with experimental results. As scientists, we are obliged to trust the experimental results, even if it means that we must abandon much of what our common sense tells us. Abaondoning this common sense view of the world is difficult for just about everyone who studies modern physics. It was particularly difficult for the pioneers who first had to make the journey without guidance from people who could reassure them they were on the right path.

The comment was that evolution exists.
The theory of evolution is an attempt to explain the known fact that evolution exists.

Choosing to believe the common sense arguments of a philosopher who died a century before quantum theory was developed doesn't make for a convincing argument.
To the extent that science can disprove philosopy, physics has pretty much blasted the "common sense reality" nature of the universe out of the water.
Our common sense view of reality is a very useful model. If we had to constantly look at the universe as a gigantic probability distribution of elementary particles all smeared over the entire area of the universe each interracting with every other, then we'd just end up sitting in a corner and drooling until we died, because we would be unable to deal with the incomprehensible complexity.
Nothing in science can be considered to be an indisputable fact, because the very nature of the scientific method requires that the only "facts" we are allowed to propose are ones which can potentially be disproven.
If chemists were forced to give up on the "Law of Conservation of Mass," a theory so strongly supported that it obtained the category of being a "Law of Science," then biologists must be equally capable of giving up the theory of evolution if sufficient evidence is found to disprove it.
I can come up with a virtually limitless number of theories to explain the "facts" of evolution without using any aspects of the theory of evolution. Those theories would generally be ridiculed as crazy, or nonsense, but there would be no evidence to disprove them, beyond the principle of Occam's Razor.
Part of the confusion in this discussion is based on the multiple uses of the word "evolution."
Certainly, the idea that scientists have observed changes in the structure of a species of organism over several life cycles which tend to help the species adapt to a new environment is a well established fact. If we label this behavior as "evolution," then evolution is a principle which has been observed by many people under many different circumstances, and could be refered to as a fact, without any objection from me.
The original comment in this discussion stated that "evolution is a fact, the theory of evolution explains this fact." If we interpret that rather terse statement as another commenter did, saying:
then I agree. Observations of the behavior of a system are the closest things to "facts" that science deals with. On the other hand, even experimental observations are subject to reinterpretation based on additional evidence.
But, using evolution to desribe both an observable phenomenon, and the theory which attempts to explain that observable phenomenon causes needless confusion.
And ultimately, I still agree with the comment about the Chemistry Prof who said that there are no "facts" in science. There are observations, and there are theories. Experimental error can cause observations to be incorrect. New observations can cause theories to be incorrect.
I can't currently think of a source of experimental error which would invalidate all of the observations of evolutionary behavior which have been made. But that doesn't mean that there is no possibility that such an error could exist.
Also, you state that "phenomena exist."
I agree. What I don't agree with is that our perceptions of phenomena are always accurate representations of the ultimate reality of those pheomena. Just like the table top. It looks solid. It feels solid. But any chemist knows that it is almost entirely composed of empty space.

Science is an attempt to separate the likely from the fantastic.
I do not personally question the theory of evolution. It is still a theory and taught as such, so it must reasonable still be treated as such.
ID is so far off base, no reasonable person would accept it as a refutation of evolution.
You are saying that events occur which demonstrate that one organism can evolve into a different organism over time. I agree.

And refer them to the Tao te Ching, the Bhagavad Gita, the Koran, and the Book of the Subgenius available in their church library and gift shop?

Compare the two and tell me how intelligent design makes sense of all the junk in the human AND chimp genomes being virtually the same "junk" (non-coding) DNA?
As to the main thread, it is clear they are funneling local church money into the curriculum in this little school district in PA and lying about it and disguising it. Because only churches embrace intelligent design and want to teach it in school. Commandments about false witness seem appropriate to bring up in this context.

Actually, I think my daughter's 5th grade teacher did something really interesting, which is when they started their social studies curriculum which looked at human evolution, they did a unit on origin myths and students could discuss their religious/cultural beliefs and traditions. Then the idea of what a scientific approach, as opposed to a faith-based or tradition based one, is was introduced. Not that you could get away with that in most schools, but I thought it was very powerful especially since her classmates included everything from Pentacostal to atheist.
by bronxdem on Thu Nov 03, 2005 at 04:26:49 AM PDT
One of the main reasons is because I want to be able to teach things like your daughter learned. I don't see any problem with it. It's not an endorsement of any religion, and it explains why creationism and ID aren't taught as part of science. I personally feel that dodging the question is what gives the creationists the ammo to claim we need to teach their views.

I know you know this- it isn't parents like you that are the problem. It isn't teachers like your daughter's that are the problem. It is the people who want to slide in the young earth and intelligent design as science. And science says, "We can't say there is a God." I believe that is why they call it faith.
But having faith that something that is physically impossible is true requires such a complex, alternate, version of reality. Believing in creation on October 23, 4004 BC at 9:00 in the morning (we celebrate this as Bishop Usher Day in our family) requires believing in a creator out to trick you and test your faith. And this is seriously what many people in the US believe and want to teach their children and our children if they can.
And then you get all the bogus history channel and Fox and msNBC shows on Noah's ark on a mountain top to reinforce the ignorance. Like we don't have satellites and people who can climb a mountain to excavate. How do we get all that stuff out of the Andes?
Sorry for the rant- but this is something that is very frustrating. Duane Gish and his ilk have been running these scams for over 35 years- I first saw the obviously faked dinosaur walks with man in the riverbed film as an undergraduate then. I am almost at the point of the scientists in Kansas who just said- Basta- enough. We won't discuss this further. If you insist, we take away your right to call this type of education science.

But yes, there is a lot to learn by careful evaluation of false theories and models, and investigating how some very clever people developed some very incorrect notions.
Fortunately, human understanding is capable of evolution, too. Although sometimes it seems highly punctuated.

The Dover school board went off the reservation with their push to actually teach ID, and this overreach has and will hurt the ID movement. This trial can establish much more clearly that ID is creationism, plain and simple, and undermine the more subtle approach favored by the DI.
Hee hee.
