Bettawrekonize -> RE: Many High School Biology Teachers Still Teach Creationism (5/21/2008 5:09:51 PM)

quote:
ORIGINAL: gluadys This is exactly my point. The problem is that it seems some committed naturalists are aware of the fact that the notion that the emergence of everything is explainable through naturalistic processes is indefendable so they advocate the censorship of anything that may contradict their metaphysics. How about I propose this. They don't have to label it science, they can label it philosophy as long as they require everyone who is introduced to UCD and other naturalistic philosophies to be introduced to criticisms and opposing views (like ID and creationism). I also want them to teach that we argue that the purpose of science is to find best explanations, and not the best naturalistic explanations, and that limiting science to the best naturalistic explanations means that if the best explanations may contradict naturalism, science will be unable to find them. Then they can teach students that we believe the criteria for science is falsifiability and why we believe ID and creationism are more falsifiable than UCD. They can try to refute this all they want, as long as they teach students this. If your arguments stand up to scrutiny, you should have no problems with this. quote:
But creationism, as science, has been falsified as thoroughly as geocentrism (though I don't expect you want that taught), and both creationism and ID do require introducing something other than science into the curriculum. I do not think that creationism, as a science, has been falsified as strongly as UCD and other naturalistic philosophies; however, if they want to teach naturalistic philosophies (like UCD) they should likewise teach criticisms of naturalistic philosophies, opposing views, and criticisms of those opposing views. quote:
This from the person who does not recognize what falsification is; probably because you don't recognize the nature of evidence either. Both Method and I have presented you with clear means of falsifying UCD. You should be free to introduce students to these alleged falsification schemes provided that you introduce them to my counterarguments. If your falsification schemes are reasonable, you should have no problem believing that students will accept them over my counterarguments. That's all I ask. The only reason to refuse is if you know that your arguments are nonsense and you don't want students to realize this. If your alleged falsification schemes are as reasonable as you claim, you should have no problems introducing students to my counterarguments. quote:
Absolutely, there is. If you inherit your DNA from your ancestors, you also inherit the particular coding system used. If your DNA codes for methionine with ATG, you can be sure that was true of your ancestors too. If your DNA codes for eyes, you can be sure that your ancestors DNA did the same. So then, following your logic, how did eyes originate? Are you alleging that all of our alleged ancestors had eyes? If not, then it's possible for our alleged ancestor to not have something that we have. To continue with your logic, eyes are subject to evolutionary change. The eyes of chimps are different than the eyes of humans, yet evolution contends that we acquired eyes from a common ancestor. Clearly, if our eyes were identical to the eyes of our alleged common ancestor and the eyes of chimps are identical the the eyes of our alleged common ancestor, then our eyes would be identical to the eyes of chimps. Yet, our eyes are not identical to the eyes of chimps which means that, if UCD is true, one or both of our eyes have changed since we acquired them from our alleged ancestor. If UCD is true, this means that eyes are subject to evolutionary change. If eyes can change, then there is no reason why ATP (or ATG) can't change (unless ATP gives a survival advantage). quote:
Can you imagine species with different coding systems mating? If ATG means 'methionine' in your father's DNA but 'glycine' in your mother's DNA, which amino acid will your cells produce? What protein will be constructed? Uhm... Species with different eye colors have offspring. quote:
Species using a different DNA coding cannot possibly share a common ancestor. How could the same ancestor pass on two different coding systems? Different humans have different eye colors yet, according to UCD, all humans share a common ancestor. This is like me asking, how can the same ancestor pass off two different eye colors? You're not understanding the argument being made. Please, at least try to understand it. You don't seem to even understand how evolution allegedly works (or was thought to work). The changes that allegedly code for these new structures allegedly start with mutations in germ lines. If mutations in germ lines can produce all the changes required to produce all the complex structures of living organisms, it requires a leap of faith to say that they are unable to change, have never changed, and will never change ATP into something else (unless ATP provides an advantage). quote:
UCD doesn't predict that it will be ATG that codes for methionine. But it does predict that if an organism in which ATG codes for methionine reproduces, its descendants will use the same codon for the same purpose. It won't switch to using ATG for valine or serine instead of methionine. Just because you (or anyone else) allege it predicts this does not make it so. There is no reason for UCD to predict this. quote:
If there were an ancestor that used CGC for methionine instead of ATG, then when it reproduced, its descendants would use CGC for the same purpose. And we could tell that the two groups had different ancestors by the fact that each codes for methionine with a different codon, and each uses the other codon for a different amino acid. There is no reason for this to indicate that these groups don't share a common ancestor. quote:
That would be a falsification of UCD. No, it would not. quote:
We do not observe that, however, so UCD is a logical conclusion of what we do observe: universal use of the same DNA codons. We do not observe that, so UCD is an illogical conclusion of what we do observe. Universal use of the same codon is not what UCD should predict.
