Unless you have billions of years to make this even remotely possible the idea is patently absurd.

No, that's abiogenesis and it's completely different and separate from evolution.

And regardless, it's not a belief. It's a well-founded theory with plenty of evidence and study:

And here's what is most probably the most exciting hypothesis to arise in the past little while:

TLDR: Life is the most effective agent of entropy.

0___0, Tim, are you trolling me? Einstein himself made several revisions during the course of his research:

https://en.wikipedia.org/wiki/Histor...ral_relativity

"By 1912, Einstein was actively seeking a theory in which gravitation was explained as a geometric phenomenon. At the urging of Tullio Levi-Civita, Einstein began by exploring the use of general covariance (which is essentially the use of curvature tensors) to create a gravitational theory. However, in 1913 Einstein abandoned that approach, arguing that it is inconsistent based on the "hole argument". In 1914 and much of 1915, Einstein was trying to create field equations based on another approach. When that approach was proven to be inconsistent, Einstein revisited the concept of general covariance and discovered that the hole argument was flawed.[15]"

Notwithstanding, should better data become available to discredit or partition our previous understanding or relativity, it WILL be ensconced into the body of knowledge. And, as it turns out, we are adding to relativity. Again, science is both additive and revisionist. What separates so-called "good" from "bad" science is the adhesion to truth without flaws in methodology or personal dogma.

Lewin reported, "The central question of the Chicago conference was whether the mechanisms underlying microevolution can be extrapolated to explain the phenomena of macroevolution. At the risk of doing violence to the positions of some of the people at the meeting, the answer can be given as a clear, No." (Roger Lewin, "Evolutionary Theory Under Fire," Science, Vol. 210:883-887, Nov. 1980.)

That's a load of poppycock. That entire website is a proponent of ID... AND We have seen speciation happen before our eyes:

So any detractors can f-ck right off.

"The punctuated equilibrium model has been widely accepted, not because it has a compelling theoretical basis but because it appears to resolve a dilemma. ... apart from its intrinsic circularity (one could argue that speciation can occur only when phyletic change is rapid, not vice versa), the model is more ad hoc explanation than theory, and it rests on shaky ground.

(Science, Vol. 199:58-60, Jan. 6, 1978.)

Speciation is just inbreeding on a large scale. We all know how good inbreeding is for weird genetics. ;-D

Please link source (the fact that it's from 1978, virtual bygones when it comes to the current field of evolutionary study).

This is not a bait and switch, it is analogous and perfectly valid layman's terms to describe the fallacy of equating micro/macroevolution as some sort of candid 'gotcha!' If you want, I can retract his and provide a perfectly list of studies:

Some creationists respond to the studies. " But once again, this rapid adaptation (which can lead to speciation) fits well within the creation model." Apparently, only one "kind" of thing changing into another "kind" of thing is evolution, whatever that means.

To preemptively rebut this type of thing, I'm going to include this summary of observed examples of speciation. But really, if up to this point, these examples don't lend you pause, nothing going to change no matter what evidence I provide :P

Here's the juicy bits. From the last paragraph on page 198.

"The bones, catalogued as TMM 42475-1, apparently represent a quick surface collec-
tion by Liscomb, and consist of fragments of limb bones, ribs, and vertebrae. The quality
of preservation is remarkable. The bones are stained a dark red brown but otherwise dis-
play little permineralization, crushing, or distortion."

Dude, surface collection ≠ recent and I already provided a mechanism to explain the remarkable, non-fossilized preservation. The lack of crushing or distortion is a matter of lucky geology, and has little, if anything to do with evolution. Bet you those fossils can be carbon dated to, oh, I dunno, 85-67 MYA, should anyone decide it was worth their time.

I mean, hell, from that article:

The site occurs in what is mapped as undifferentiated Upper Colville Group of Late Cretaceous age, which is overlain by the Plio(?)-Pleistocene Gubik Formation (Brosgk and Whittington, 1966). Recent studies, however, have indicated Paleogene rocks in this region (Carter et al., 1977; Nelson, 198 1; Marincovich et al., 1983). Pending resolution of the stratigraphy, beds underlying the Gubik Formation in the region are being referred to simply as "pre-Gubik" (Carter et al., 1977; R. V. Emmons, personal commun.). Hadrosaurs are exclusively Late Cretaceous and their presence limits the age of the pre-Gubik rocks. "This datum has allowed H. J. Clippinger to interpret somewhat contaminated pollen samples and establish a Maastrichtian or possibly Campanian age for the strata 28 feet above and 12 feet below the dinosaur bed. Foraminifera 2 feet below the bone bed indicate a shallow marine environment" (Shell Oil Company memorandum, with permission of R. V. Emmons and H. J. Clippinger)

I don't understand the argument. We have never extracted DNA from dinosaur-era fossiles. I mean... it says so right in the title of the article you linked...

0___0 c'mon man, at least read my links, I read yours.

Gosh darnit. No, this is not how it works and no, it does not violate the 2nd law of Thermodynamics. Speciation is the separation of allele frequencies between two previously nested hierarchies producing traits which make them observably different and/or genetically incompatible.

Ehm, now, that is a possibility and an intriguing possibility and I suppose it’s possible that you might find evidence for that if you look at the um detail, details, of biochemistry, molecular biology, you might find a signature of some sort of designer. "


Prof Dawkins is smart enough to know what he believes and how to properly express it.

Anyways, after being accused of setting up a Strawman argument and then having you try a few Bait and Switch and your own Strawman. I don't think this debate is going to go anywhere positive so it's not worth continuing. I think we can agree to disagree and still be good reefers. :-)

... I don't even know how to respond to that. I provided a video of him explaining the situation. Literally, out of his mouth, he elaborated how Ben Stein mislead him and then used the interview to further his agenda.

And no, I haven't resorted to any bait/switch strawman arguments. The closest approximation you can make to that is when I used analogies to help illustrate a point in layman's terms.

C'mon Tim, I'm not attacking you. We're having a debate. It is a back and forth. This is not meant to be an attack on your beliefs. But if you're going to take it as such, then I guess I'll duck out of this one also :P

This is a interest thread and I wish I could add some interesting intellectual comment that would impress my fellow board members but instead I think I will just continue watching Die Hard and continue my mindless de-evolution.

[msjboy]

Seems many factors change the DNA very quickly as opposed to thousands of years :


eg) red foxes caught from the wild within a couple of generations change colours and become docile

b) humans who snorkel with suntan lotion has some DNA effect on the corals nearby ( the corals have some DNA changes that would be detrimental to it )

c) the folks at AMI in austraila are trying to breed super corals that would be more resistant to the climatic changes going on in hopes of saving the natural brood stock out there... this can happen in relatively a short span of an years as opposed to the thousands of years of natural incremental changes


and the root of it is of course mankind. I am sure the feed the hatcheries get has weird medicines and steroids of some sort to keep the fish from getting sick and grow faster.

[WarDog]

Excellent debate people.
