@gungasnake,
In case anyone thinks I'm being a bit harsh, I'll add an explanation of why gunga's got no idea what he's talking about (or worse, knows what he's talking about and realizes that it's false).
gungasnake wrote:The original formulation of evolution, Darwinian gradualism, demanded that living forms be in a permanent state of flux and therefore also that the vast bulk of all fossils be intermediate forms.
If by gradualism you mean rather slow step-wise changes, none of that has changed. If you mean phyletic gradualism, as attacked by Gould and countered by Punctuated Equilibrium, then that is not something Darwin was enamored with. Gould himself claimed his ideas to be more consistent with Darwin's open-mindedness on this subject.
gungasnake wrote:Nonetheless it is well known that there are no such transitional forms.
No, it isn't. That statement is accepted by rather gullible creationists who either don't know what a transitional form is, don't have the faintest clue about the evidence, or both. Or, in the case of someone like Kent Hovind, they know better but choose to lie.
First, what's a transitional form? It is an animal or group of animals which shares homologous traits from a common ancestor between two reference populations/animals: an earlier one and a later one. For example, a platypus is a transitional form of mammal between the origin of mammals and the evolution of mammalian vivipary. Notice that a transitional form need not be a fossil: what is important is the phylogeny and the traits. For a fossil example, you can take Indohyus, a transitional form between whales' land ancestors and their various modern forms (or Basilosaurus, etc. You get it even if gunga doesn't).
gungasnake wrote:Steve Gould and a number of his associates went to the trouble to devise an entirely new version of evolution ( punctuated equilibria) precisely to explain this lack of intermediate forms and the actual geological record which indicates that animal species arise fully formed at fixed points in time, go on for long periods without meaningful change, and then either die out or are still walking around in their original forms other than for changes which one could call MICRO-evolution, which nobody disputes.
Nonsense, punk-eek was an explanation for the fact that they identified some relative stasis in fossil remains, not some rationalization for a lack of transitional forms. There are countless examples of transitional forms. I've also seen creationists deny microevolution repeatedly, usually when it contradicts their pitiful attempts at attacking biology. Even ID is contradicted by microevolution, as many changes which should clearly be 'irreducibly complex' occur over observable periods: less than 20 years.
gungasnake wrote: The sort of claim which farmerman makes is therefore seen as bullshit. If there actually were even as many as a hundred such forms in existence, Gould, Eldridge, Mayr et. al. very obviously would not have gone to all that trouble.
Yes, they would have, because they had an actual understanding of the evidence. There are *some* clear examples of stasis vs. punctuation, but it certainly doesn't indicate a lack of transitional forms. You could easily educate yourself on what transitional means and find huge numbers of examples, but you refuse to (or try to rationalize them away). The evidence is there, it *has been* there for some time.
gungasnake wrote: What evolutionites actually have is a little collection of oddities, the nature of which are open to interpretation, and most if not all of them are debunked within a few years of their turning up.
Uh, no. It is possible to find an almost limitless number of transitional forms in what has already been discovered. The entirety of the phylogenies (which overlap, by the way) generated by molecular and fossil evidence supply an ample number. We merely cite the ones that are easy for people to identify with: whale transitions, for example. These easy examples are, surprisingly enough, not understood or ignored by creationists.
"evolutionites"? "Darwinists"? You can't handle a lack of a label, can ya? Sorry, there's only two main groups here: the people who accept and usually understand the overwhelming evidence underlying evolutionary theory, and those who don't.
Hilarious resources. Free Republic and the idiot Luskin. Tiktaalik isn't merely intermediate between fish and walking creatures, it is an intermediate between a fairly fine gradation of pre-tetrapods, where the homologous trait of attention is the layout of what would eventually become radial bones (hands, etc).
I won't waste everyone's time by going through the whole articles. That would be buying into the Gish Gallop and there are plenty of resources where you can confirm that they are indeed full of s***. Luskin's ignorance of and incompetence at comprehending science is so great that I wouldn't trust him to teach basic physics to 4th graders even if we gave him a year to prepare.

It's only been "abandoned" by silly deniers like yourself. Not only is archeopteryx still an excellent teaching tool (easy to understand for *most* people) and quite accurately a transitional form between non-avian dinosaurs and avians, but there have been a huge number of fossils discovered which do the same, whether it's a Deinonychus with 'pinion-feather holes' or Tyrannosaurus rex juveniles covered in down.
gungasnake wrote:Modern paleontology has consistently placed Archaeopteryx as the most primitive bird. It is not thought to be a true ancestor of modern birds but, rather, a close relative of that ancestor (see Avialae and Aves).[54]
Nonetheless, Archaeopteryx is so often used as a model of the true ancestral bird that it has seemed almost heretical to suggest otherwise.
The person you're quoting is rather stupid to be publishing without, you know, checking with someone with the bare minimum of knowledge on the subject. The only place it would seem 'heretical' to suggest such a thing would be in mainstream nature media, which usually gets that stuff wrong. Perhaps some day creationists will understand the difference between the Discovery Channel and a science textbook.
Of course transitional forms are to be seen as relatives of the actual ancestor of interest. That's how they've *always* been viewed by actual scientists working on the subject. While it is possible that some belong to the actual ancestral populations of living descendant species, it is not something which can be inferred from morphology alone. It's a bit strange that you'd even cite a random anonymous website question-answer, in my opinion.... The "controversies" that it cites are arguments about precisely where archaeopteryx fits in the phylogeny, not whether it's a transitional form. That is, those outside of the idiotic nonsense published by Hoyle and others.
