That's the whole reason for pe, knotted, to explain why what's being found didn't meet what Darwin predicted.

What Darwin seemed to predict on certain occassions.

What Darwin predicted and what Darwin's theory predict are two different things of course.

An example from a different field:
Newton's theory of gravitation does predicts certain anomalies in the orbit of Uranus given the existence of Neptune. Newton never predicted the existence of Neptune, therefore he never predicted the anomalies in the orbit of Uranus. Does this mean Newton's theory of gravity has been completely falsified, or does it mean that Neptune exists?

What a theory predicts is dependent on what assumptions you make. If for example you are assuming that most speciation is sympatric then Darwin's theory might make different predictions than if you assume that most speciation is allopatric or peripatric.

Make sense?
 
Searching gamely for some common ground here...

... can we all agree that the classical Darwinist paradigm is outmoded and in need of revision?

"seemed to predict" - well, what were Gould and Eldredge wasting their time for?

At least you're trying now...

How about this knotted - looks like almost all speciation over the millions of years happened off the radar? What does that tell you?

Remember that quote Santino posted? Also that article on talk.origins casts doubt on Gould's characterisation of Darwin's beliefs. Not that it really matters, as I explained above. We're assessing the theory not the man.

That speciation is hard to pick up on the radar?

It's not as if we don't know about speciation. It's something that's been observed in the laboritory.
 
And no I'm not trying now. This is very basic stuff and we have just been through it all once already.
 
From the original paper on punctuated equilibrium.

Our two examples, so widely separated in scale, age, and subject, have much in common as exemplars of allopatric processes. Both required an attention to details of geographic distribution for their elucidation. Both involved a more literal reading of the fossil record than is allowed under the unconscious guidance of phyletic gradualism. Both are characterised by rapid evolutionary events punctuating a history of stasis. These are among the expected consequences if most fossil species arose by allopatric speciation in small, periphally isolated populations. The alternative picture merely represents the application to the fossil record of the dominant theory of speciation in modern evolutionary thought. We believe that the consequences of this theory are more nearly demonstrated than those of phyletic gradualism by the fossil record of the vast majority of Metazoa.

Punctuated equilibrium was in full accordance with evolutionary orthodoxy. It actually used the dominant theory of speciation at that time - allopatric speciation of small, periphal populations (ie. peripatric speciation) and applied it to the fossil record with positive results. It was a confirmation of the evolutionary orthodoxy. Plus it helps explain why it is difficult to find transitional forms in the fossil record at the species level (although there is an abundance of transitional forms at higher levels). So what's the fuss?

Yes, your elementary understanding of pe and darwinian evolution is simple stuff. That's why you think everything's fine. And if even paleontologists themselves take up issue with the fossil record you've said, "Drivel is drivel regardless of who speaks it."

No that nearly every animal back then was evolving out of sight of the fossil record. Seem odd at all to you?

:facepalm:

Only when it's actually drivel.

Do you see what you did there? You've just confused speciation with all evolution.

No it wasn't, that's why it was a hard sell in the beginning.

So if we know the overwhelming majority of animals were evolving via pe then shouldn't the schoolbooks be changed to reflect that instead of promoting what Eldredge called the "conventional theory" (like I've been telling you and you've kept denying exists).

What is the conventional theory knotted?

Allopatric speciation.

I don't think they have ever claimed that the overwhelming majority of species evolve via punctuated equilibrium.

"Allopatric speciation" huh? No it was darwinian gradualism. Phillip Johnson quoted Eldredge in his book Darwin on Trial -

"Either you stick to the conventional theory despite the rather poor fit of the fossils, or you focus on the empirics and say that saltation looks like a reasonable model of the evolutionary process - in which case you must embrace a set of rather dubious biological propositions." - Niles Eldredge

You're bent on denial, knotted. If anything at all disagrees with your strange ideas of darwinism or pe you're going to simply deny it - even when it's from the authors of pe or other darwinists scientists.
 
See I told you it was about saltationism not stasis. You fool.

Right, that's a curious quote. I'll look it up.
 
I can't even find the quote in Johnson's book. It seems to be a fake. Even Johnson admits:

Gould and Eldredge have consistently described punctuated equilibrium as a Darwinist theory, not a saltationist repudiation of Darwinism. On the other hand, it is easy to see how some people got the impression that saltationism was at least being hinted, if not explicitly advocated. Gould and Eldredge put two quotes by T. H. Huxley on the front of their 1977 paper, both complaints about Darwin's refusal to allow a little "saltus" in his theory. At about
the same time, Gould independently endorsed a qualified saltationism and predicted Goldschmidt's vindication.
 
OK found it in Johnson's book. No citation. Johnson's clearly all over the place, but it's still a curious quote.
 
Could it be Reinventing Darwin: Great Evolutionary Debate by Niles Eldredge?

I've done a search on amazon. It's definately not from that book.

It's so ridiculous that it's surely either fake or taken completely out of context. The fossil record can't possibly show saltations. Saltations do exist, but what's one generation in the rock face?
 
OK it was from Time Frames. Here's the quote in full:

So, here's a bit of a dilemma. When we finally find some evolutionary change, however slight it may seem, the "typostrophic" sort of affair the Phacops rana lineage seems to show in the Midwest poses a choice between two unappetizing alternatives: either you stick to conventional theory despite a rather poor fit of the fossils, or you focus on the empirics and say that saltation looks like a reasonable model of the evolutionary process--in which case you must embrace a set of rather dubious biological propositions. Paleontologists are rather well known for taking that latter course--adopting ad hoc, outmoded and sometimes downright mystical ideas about biological processes just because they fancy these ideas fit what they think they see in the fossil record. I had every desire to avoid that well-trodden path. Besides, I was (and remain) too much of a conventional neo-Darwinian ever to subscribe to the saltationist heresy.
