The "junk" claims are often not universal amongst evolutionists, but sometimes they do seem to be. Each case is different. It is safe to say, however, that evolutionary theory has repeatedly led different evolutionists, at different times, studying different structures, to expect or conclude "junky-ness". It is an enduring theme, and for obvious reasons.<br /><br />Furthermore, this expectation rapidly becomes, if not is initially, metaphysical. For instance, the later finding of function and even efficiency, usually makes no difference because the design never was to our liking.<br /><br /><br />"A shocking rebuttal to evolution? No."<br /><br />But of course that was not the point. Another evolutionary strawman.Cornelius Hunterhttps://www.blogger.com/profile/12283098537456505707noreply@blogger.comtag:blogger.com,1999:blog-3855268335402896473.post-55323444239059779442010-02-17T20:58:36.115-08:002010-02-17T20:58:36.115-08:00I'm not sure how seriously anyone would ever c...I'm not sure how seriously anyone would ever consider the proposal that flexible regions are junk. The suggestion they are functional goes back to Pauling. Actually, it was the conservation of some of these regions in evolution that suggested biochemists better hunt for a function for them. The quoted scientist is saying intrinsically disordered or 'NORS' regions had no APPARENT function. 'Junk' in quotes. But he went looking for functionality and found it. A shocking rebuttal to evolution? No. I'm not sure how design hypothesis would do better, especially as we are not supposed to infer the intent of the designer. I have owned several cars that have designed parts with no function-weird fins, a faux-spoiler, little hood ornaments, mounting brackets that go with another model.... <br /><br />Ref:<br />Loopy Proteins Appear Conserved in Evolution<br />Journal of Molecular Biology<br />Volume 322, Issue 1, 6 September 2002, Pages 53-64RobertChttps://www.blogger.com/profile/15755085870566406648noreply@blogger.comtag:blogger.com,1999:blog-3855268335402896473.post-23749156874555336762010-02-17T05:24:51.572-08:002010-02-17T05:24:51.572-08:00Cornelius Hunter: One problem with evolution is it...<b>Cornelius Hunter</b>: <i>One problem with evolution is its strong bias toward viewing everything in biology as a kludge. </i><br /><br />A first-order approximation is that natural selection would limit the amount of "junk", but the process and rate of optimization depends on the relative costs involved. <br /><br /><b>Cornelius Hunter</b>: <i>The once-we-thought-it-was-junk-but-now-we-see-how-it-works is a consistent theme in evolutionary thought. </i><br /><br />You're confusing theory with data. Whenever something new or interesting is discovered, you imply that it undermines the Theory of Evolution somehow or other. New and interesting things are discovered every day, but the scientists making these discoveries keep talking as if evolution was involved, oblivious to what is obvious to you.Zachrielhttps://www.blogger.com/profile/11268229653808829377noreply@blogger.comtag:blogger.com,1999:blog-3855268335402896473.post-13001141559304408412010-02-17T05:15:12.216-08:002010-02-17T05:15:12.216-08:00Cornelius -

The evolutionist’s going in position is that biology is a fluke. We’re lucky anything works."<br /><br />A total grotesque of a strawman argument. Especially from one who claims to understand how it works.<br /><br />Evolution through natural selection is not 'random chance'. It is a blind process, true, but that only means there is no forward planning. Mutations are not planned and animals cannot keep a non-beneficial mutation just because it will be useful to them in the future, for example.<br /><br />That is not to say the entire process is a fluke, and it is a woefully common Cretionist/ID fallacy to claim it is. Such faulty thinking leads people to claim the intimidating height of Mount Improbable is impossible to climb.Ritchiehttps://www.blogger.com/profile/03494987782757049380noreply@blogger.comtag:blogger.com,1999:blog-3855268335402896473.post-74176205750543491392010-02-17T02:47:54.467-08:002010-02-17T02:47:54.467-08:00William Bialek - Professor Of Physics - Princeton ...William Bialek - Professor Of Physics - Princeton University:<br />Excerpt: "A central theme in my research is an appreciation for how well things “work” in biological systems. It is, after all, some notion of functional behavior that distinguishes life from inanimate matter, and it is a challenge to quantify this functionality in a language that parallels our characterization of other physical systems. Strikingly, when we do this (and there are not so many cases where it has been done!), the performance of biological systems often approaches some limits set by basic physical principles. While it is popular to view biological mechanisms as an historical record of evolutionary and developmental compromises, these observations on functional performance point toward a very different view of life as having selected a set of near optimal mechanisms for its most crucial tasks."<br />http://www.princeton.edu/~wbialek/wbialek.htmlbornagain77https://www.blogger.com/profile/16666666037080692370noreply@blogger.com
