Where is that fellow who doesn't believe in evolution and that's the end of it?

Hmm, there are a bunch of creationists on FR. I think the latest one was exnilhio(sp?). He was posting Intelligent Design articles that had been discussed before. There is also Gore3000, and medved. I get a kick out of medved, because his pet theory is that the earth used to revolve around Saturn.

in the same way the nipple is used to feed mammalian young and also as a tool for sophisticated nest construction.

That must be a very interesting procedure to watch.

No, no. That can't be "medved's" pet theory.

"medved's" pet theory is that pets are psychic, and can tell what their masters are thinking!

His "Earth orbiting Saturn" is just one of his "regular" theories.....

;-)

I suppose he is following the lead of evolutionists who group fossils according to common factors and determine ancestry from the same.

A Change of Seasons on Saturn

Saturn's equator is tilted relative to its orbit by 27 degrees, very similar to the 23-degree tilt of the Earth. As Saturn moves along its orbit, first one hemisphere, then the other is tilted towards the Sun. This cyclical change causes seasons on Saturn, just as the changing orientation of Earth's tilt causes seasons on our planet. The first image in this sequence, on the lower left, was taken soon after the autumnal equinox in Saturn's Northern Hemisphere (which is the same as the spring equinox in its Southern Hemisphere).

The really big lie which is being promulgated by the evos is that the dialectic is between evolution and religion. That's BS. In order to have a meaningful dialectic between evolution and religion, you would need a religion which operated on an intellectual level similar to that of evolution, so that the debate would be between the evolutionists, and the voodoo doctors: Dick Dawkins vs Jr. Doc Duvalier.

But the real dialectic is between evolution and mathematics. Professing belief in evolution at this juncture amounts to the same thing as claiming not to believe in modern mathematics, probability theory, and logic. It's basically ignorant.

Evolution has been so thoroughly discredited at this point that you assume nobody is defending it because they believe in it anymore, and that they are defending it because they do not like the prospects of having to defend or explain some expect of their lifestyles to God, St. Peter, Muhammed...

To these people I say, you've still got a problem. The problem is that evolution, as a doctrine, is so overwhelmingly STUPID that, faced with a choice of wearing a sweatshirt with a scarlet letter A for Adulteror, F for Fornicator or some such traditional design, or or a big scarlet letter I for IDIOT, you'd actually be better off sticking with one of the traditional choices because, as Clint Eastwood noted in The Good, The Bad, and The Ugly:

God hates IDIOTS, too!

The best illustration of how stupid evolutionism really is involves trying to become some totally new animal with new organs, a new basic plan for existence, and new requirements for integration between both old and new organs.

Take flying birds for example; suppose you aren't one, and you want to become one. You'll need a baker's dozen highly specialized systems, including wings, flight feathers, a specialized light bone structure, specialized flow-through design heart and lungs, specialized tail, specialized general balance parameters etc.

For starters, every one of these things would be antifunctional until the day on which the whole thing came together, so that the chances of evolving any of these things by any process resembling evolution (mutations plus selection) would amount to an infinitessimal, i.e. one divided by some gigantic number.

In probability theory, to compute the probability of two things happening at once, you multiply the probabilities together. That says that the likelihood of all these things ever happening, best case, is ten or twelve such infinitessimals multiplied together, i.e. a tenth or twelth-order infinitessimal. The whole history of the universe isn't long enough for that to happen once.

All of that was the best case. In real life, it's even worse than that. In real life, natural selection could not plausibly select for hoped-for functionality, which is what would be required in order to evolve flight feathers on something which could not fly apriori. In real life, all you'd ever get would some sort of a random walk around some starting point, rather than the unidircetional march towards a future requirement which evolution requires.

And the real killer, i.e. the thing which simply kills evolutionism dead, is the following consideration: In real life, assuming you were to somehow miraculously evolve the first feature you'd need to become a flying bird, then by the time another 10,000 generations rolled around and you evolved the second such reature, the first, having been disfunctional/antifunctional all the while, would have DE-EVOLVED and either disappeared altogether or become vestigial.

Now, it would be miraculous if, given all the above, some new kind of complex creature with new organs and a new basic plan for life had ever evolved ONCE.

Evolutionism, however (the Theory of Evolution) requires that this has happened countless billions of times, i.e. an essentially infinite number of absolutely zero probability events.

And, if you were starting to think that nothing could possibly be any stupider than believing in evolution despite all of the above (i.e. that the basic stupidity of evolutionism starting from 1980 or thereabouts could not possibly be improved upon), think again. Because there is zero evidence in the fossil record (despite the BS claims of talk.origins "crew" and others of their ilk) to support any sort of a theory involving macroevolution, and because the original conceptions of evolution are flatly refuted by developments in population genetics since the 1950's, the latest incarnation of this theory, Steve Gould and Niles Eldredge's "Punctuated Equilibrium or punc-eek" attempts to claim that these wholesale violations of probabilistic laws all occurred so suddenly as to never leave evidence in the fossil record, and that they all occurred amongst tiny groups of animals living in "peripheral" areas. That says that some velocirapter who wanted to be a bird got together with fifty of his friends and said:

Guys, we need flight feathers, and wings, and specialized bones, hearts, lungs, and tails, and we need em NOW; not two years from now. Everybody ready, all together now: OOOOOMMMMMMMMMMMMMmmmmmmmmmmmmmmmmmmmmmmmmmmmmm.....

You could devise a new religion by taking the single stupidest doctrine from each of the existing religions, and it would not be as stupid as THAT.

But it gets even stupider.

Again, the original Darwinian vision of gradualistic evolution is flatly refuted by the fossil record (Darwinian evolution demanded that the vast bulk of ALL fossils be intermediates) and by the findings of population genetics, particularly the Haldane dilemma and the impossible time requirements for spreading genetic changes through any sizeable herd of animals.

Consider what Gould and other punk-eekers are saying. Punc-eek amounts to a claim that all meaningful evolutionary change takes place in peripheral areas, amongst tiny groups of animals which develop some genetic advantage, and then move out and overwhelm, outcompete, and replace the larger herds. They are claiming that this eliminates the need to spread genetic change through any sizeable herd of animals and, at the same time, is why we never find intermediate fossils (since there are never enough of these CHANGELINGS to leave fossil evidence).

Obvious problems with punctuated equilibria include, minimally:

1. It is a pure pseudoscience seeking to explain and actually be proved by a lack of evidence rather than by evidence (all the missing intermediate fossils). Similarly, Cotton Mather claimed that the fact that nobody had ever seen or heard a witch was proof they were there (if you could see or hear them, they wouldn't be witches...) The best example of that sort of logic in fact that there ever was was Michael O'Donahue's parody of the Connecticut Yankee (New York Yankee in King Arthur's Court) which showed Reggie looking for a low outside fastball and then getting beaned cold by a high inside one, the people feeling Reggie's wrist for pulse, and Reggie back in Camelot, where they had him bound hand and foot. Some guy was shouting "Damned if e ain't black from ead to foot, if that ain't witchcraft I never saw it!!!", everybody was yelling "Witchcraft Trial!, Witchcraft Trial!!", and they were building a scaffold. Reggie looks at King Arthur and says "Hey man, isn't that just a tad premature, I mean we haven't even had the TRIAL yet!", and Arthur replies "You don't seem to understand, son, the hanging IS the trial; if you survive that, that means you're a witch and we gotta burn ya!!!" Again, that's precisely the sort of logic which goes into Gould's variant of evolutionism, Punk-eek.

2. PE amounts to a claim that inbreeding is the most major source of genetic advancement in the world. Apparently Steve Gould never saw Deliverance...

3. PE requires these tiny peripheral groups to conquer vastly larger groups of animals millions if not billions of times, which is like requiring Custer to win at the little Big Horn every day, for millions of years.

4. PE requires an eternal victory of animals specifically adapted to localized and parochial conditions over animals which are globally adapted, which never happens in real life.

5. For any number of reasons, you need a minimal population of any animal to be viable. This is before the tiny group even gets started in overwhelming the vast herds. A number of American species such as the heath hen became non-viable when their numbers were reduced to a few thousand; at that point, any stroke of bad luck at all, a hard winter, a skewed sex ratio in one generation, a disease of some sort, and it's all over. The heath hen was fine as long as it was spread out over the East coast of the U.S. The point at which it got penned into one of these "peripheral" areas which Gould and Eldredge see as the salvation for evolutionism, it was all over.

The sort of things noted in items 3 and 5 are generally referred to as the "gambler's problem", in this case, the problem facing the tiny group of "peripheral" animals being similar to that facing a gambler trying to beat the house in blackjack or roulette; the house could lose many hands of cards or rolls of the dice without flinching, and the globally-adapted species spread out over a continent could withstand just about anything short of a continental-scale catastrophe without going extinct, while two or three bad rolls of the dice will bankrupt the gambler, and any combination of two or three strokes of bad luck will wipe out the "peripheral" species. Gould's basic method of handling this problem is to ignore it.

And there's one other thing which should be obvious to anybody attempting to read through Gould and Eldridge's BS:

The don't even bother to try to provide a mechanism or technical explaination of any sort for this "punk-eek"

They are claiming that at certain times, amongst tiny groups of animals living in peripheral areas, a "speciation event(TM)" happens, and THEN the rest of it takes place. In other words, they are saying:

ASSUMING that Abracadabra-Shazaam(TM) happens, then the rest of the business proceeds as we have described in our scholarly discourse above!

Again, Gould and Eldridge require that the Abracadabra-Shazaam(TM) happen not just once, but countless billions of times, i.e. at least once for every kind of complex creature which has ever walked the Earth. They do not specify whether this amounts to the same Abracadabra-Shazaam each time, or a different kind of Abracadabra-Shazaam for each creature.

I ask you: How could anything be stupider or worse than that? What could possibly be worse than professing to believe in such a thing?

Hmmmph! All that passion and I don't make the cut of kooky-Creationists-to-take-note-of. Must be the fact that I too often avoid getting my heels stuck in the vitriolic evo-mire* to have made a satistactory impact.

=======================================

Doubtful; if Inclination of Axis were the appropriate criterion, one would conclude that the Earth (23.45°) more likely orbited Mars (23.98°), rather than Saturn (26.73°).

Then again, I wouldn't presuppose what the basis of "medved's" reasoning might be.

Just like the bones, a new grouping is established. Earth orbited Mars which orbited Saturn. See this grouping/evolution stuff is pretty easy. Now this theory predicts a greater tilt beyond Saturn and by golly Neptune(28.32°) fills the bill nicely. BTW my source disagrees with the Mars value of 23.98°, it has the value as 25.19°---Mars fact sheet

Ah, but YOU chose the grouping criterion to be Axis Inclination, which is why I used the subjunctive mood when referring to it.

I'm relying on 30 year-old copy of Norton's; if yours is newer and authoritative, I gladly defer to it.
