Re: THE GREAT EVOLUTION FOSSIL FAILURE
My computer seems to have slowed and so I couldn't reply to all your links at once, they took some time to load. It seems that initially these precambrian fossils were seen as related to trilobites but the resemblance is seen as superficial. ie this species was found in lower layers and died out before trilobites became common in the same areas.
All of my great-grandparents died out before I became common, but to conclude on that basis that we are not related one would have to be some sort of creationist.

Re: THE GREAT EVOLUTION FOSSIL FAILURE
I see a lot of speculation in that first link but is there any particular organism in the Cambrian explosion that you feel the Anomalocaris evolved into?
No, which is why I didn't mention Anomalocaris.

The Great Creationist Marsupial Genome Failure
I was hoping the research into the similarities and differences of the possum, kangaroo, koala and wombats of Australia would have enough information to compare their genomes precisely with the American possum with which they share common ancestry.
Your wish is granted.
The American opossums are the top two clades, the Caenolestidae and the Didelphimorphia. You notice how they don't fall within the Diprotodontia?
Under creationist theory, we would expect a near exact match between the genomes.
And as usual, creationist theory is wrong.
The DNA structure of coding genes would be the same between all five genomes apart from a few point mutations and inactive genes since their separation from their American counterparts about 4000 years ago.
Creationist theory has lead you to believe that only a few point mutations separate kangaroos and wombats?
Well, you're wrong. There are some rather gross and obvious differences. For example, "Diprotodontia contains species with both the highest (2n = 32) and lowest (2n = 10) known chromosome number for marsupials."
So, now that you know that "creationist theory" is utterly, completely, wildly wrong, you will doubtless be reappraising the respect in which you hold that "theory".

Re: The bible: 14 pairs
In your eyes the primitive soft-bodied bilaterians, and the cataphract-armored intermediates may be satisfactory intermediates. But to supply evidence for your theory you would need fossils that more closely match each of those organisms that suddenly appeared in the Cambrian. That is one of the areas where evolutionary theory fails completely.
I can make no sense out of this post.

Re: Intermediates
Its not actually a ploy, it's a legitimate requirement. Its not like we expect a complete record of intermediates, we merely require a significant record among many "species". If the intermediates are lacking it legitimately puts doubt on evolution.
Define "significant"?
Don't you think there's a bit of a double standard here? Look, in the world according to mindspawn:
(1) The Earth a mere 5000 years ago was inhabited by great big organisms with hard parts: elephants, rhinos, whales, ichthyosaurs, etc.
(2) And yet not one, none, zero of these has been discovered in fossil form in the present day.
(3) But this is not a big problem for your "theory", tralalala, no big deal.
And yet when we come and tell you that we've only found a few dozen or hundred species (WHICH IS STILL MORE THAN ZERO, MINDSPAWN) of the small, soft-bodied creatures from 540,000,000 years ago, you act like it's a major problem.
Could you not try to apply a single standard for your expectation of the preservation and discovery of fossils?
To claim that one evolved from the other is not the only logical conclusion after finding fossils in layers. What about the possibility that various species radiated out from their niche locations when the predominant environment changed? Trilobites did, they radiated out from Siberia.
Trilobite - Wikipedia
""All trilobites are thought to have originated in present-day Siberia, with subsequent distribution and radiation from this location.""
Er, mindspawn, when he says "radiation" he means evolutionary radiation. (The full paper can be read here.) But that aside, I've got to ask --- would that be the same Siberia where our supposed inability to look at the pre-Triassic fossils explains away how we can't find any Pre-Triassic mammals?

Re: Intermediates
All fossils are consistent with creationism.
Why, yes, any scenario at all is consistent with "a wizard did it". But unless the wizard is also a liar who made the whole of the fossil record into a lie, one would have to wonder why the wizard magicked up a fossil and geological record which perfectly verifies evolution.
This problem is particularly prevalent with human sequences where the fossils are normally full fledged apes or full fledged humans, and yet intermediates are claimed.
But this is manifestly false; which is why although creationists unanimously assert that the fossils are either "full fledged apes or full fledged humans" they cannot agree among themselves which is which.
Or, indeed, with themselves. So for example according to Duane Gish in his book Evolution: the challenge of the fossil record the specimen ER1470 was a "full fledged ape"; but according to Duane Gish in his book Evolution: the fossils say no it was" a "full-fledged human". Similarly in P.S. Taylor's The illustrated origins answer book Peking man is a "full-fledged ape", but in P.S. Taylor's Who's who and what's what in the world of "missing" links? it's a "fully-fledged human".
Right here on these forums we had a guy called Mazzy. One day he was writing this: "Turkana Boy is human, the others, especially the one on display at the museum in Michagan, are apes. I am remiss in my ability to understand how such intelligent scientists cannot see the difference"; and a couple of weeks later he was writing "I have no idea why any creationist would purport Turkana Boy to be human". Isn't that amazing even for a creationist --- one day he can't understand how anyone could think Turkana boy wasn't human, and yet two weeks later he can't understand why anyone would claim it was. (I pointed out to him that if he could remember what he himself was thinking two weeks previously, he might come to understand that particular mystery. He took my helpful suggestion rather poorly.)
So, if all the apemen divide neatly into apes and humans, why cannot creationists come to anything remotely resembling a consensus as to where the great gulf between them lies?
Would you like to have a go? Here's some skulls. Where would you yourself like to place the Great Divide?

Re: Intermediates
I can't really see why you'd object to human evolution anyway. (Apart from, y'know, religion.) But if you can believe that in a couple of thousand years we got from a basal bipedal archosaur such as Archosaurus to such distinctive forms as Triceraptops, Stegosaurus, Spinosaurus and Dracorex ...
... then I don't see how you can cavil at the proposition (supported by many intermediate forms) that humans descended from more basal apes over a period of millions of years.
On what basis would you believe that major morphological changes can take place over a few thousand years, but relatively minor morphological changes can't take place over millions of years?
Again, couldn't you apply a single standard to the sort of thing you find credible?
According to you, giant organisms with hard parts living 5,000 years ago can disappear from the fossil record completely without trace, but the theory of evolution is in big trouble if we can't find all of the small soft-bodied creatures from 500,000,000 years ago. And according to you, Triceraptops, Stegosaurus, Spinosaurus and Dracorex can all evolve from a Permian archosaur in a couple of thousand years, but millions of years aren't enough to get from something like this ...
... to something like this ...
... despite all the intermediate forms that exemplify the transition.

Re: Intermediates
If the fossil record is sparse, what then are you basing your theory on?
The fossils we do have.
The more logical conclusion is that organisms just appeared which is what is observed if you do not have intermediate fossils.
We have lots. You have none of the fossils that your "theory" requires. How about you discard it?

Re: The Great Creationist Marsupial Genome Failure
Is there any evidence of additional unique active coding GENES in marsupial divergence over time?
I don't know. Can you find any unique coding genes in humans that chimps don't have?
Is there any evidence of additional unique active coding GENES in marsupial divergence over time? At evolutionary rates we should expect more than a thousand additional unique active coding genes since the American possum diverged from the Australian marsupials? That would really prove the theory of evolution.
Would it prove the theory of evolution if I could find an instance of that in any clade, or does it only apply to marsupials for some reason?

Re: Intermediates
Not to delve into every one of those fossils, but archosaurs come in a variety of shapes and sizes. The dicynodont was a Permian archosaur that is often depicted with similar features to the Triceratops, albeit less dramatic. Horns and a protective skull. Similarly Procolophonids have horns and a protective skull. So I don't regard the rapid adaptation as far-fetched. The mega-sizes are the biggest difference.
The Dimetrodon was a pre-flood reptile with a sail , a similar feature to certain post-flood dinosaurs.
Wait, are you claiming that dinosaurs severally descended from different pre-Triassic reptiles, many of which were not archosaurs at all?
Then how do you explain how they all have the distinctive features of (a) diapsids (b) archosaurs (c) dinosaurs?
From WP:
The simplest and most widely agreed synapomorphies of archosaurs include teeth set in sockets, antorbital and mandibular fenestrae (openings in front of the eyes and in the jaw, respectively), and a fourth trochanter (a prominent ridge on the femur).
And:
A detailed assessment of archosaur interrelations by Sterling Nesbitt[28] confirmed or found the following twelve unambiguous synapomorphies, some previously known:
* in the skull, a supratemporal fossa (excavation) is present in front of the supratemporal fenestra, the main opening in the rear skull roof
* epipophyses, obliquely backward pointing processes on the rear top corners, present in the anterior (front) neck vertebrae behind the atlas and axis, the first two neck vertebrae
* apex of deltopectoral crest (a projection on which the deltopectoral muscles attach) located at or more than 30% down the length of the humerus (upper arm bone)
* radius, a lower arm bone, shorter than 80% of humerus length
* fourth trochanter (projection where the caudofemoralis muscle attaches on the inner rear shaft) on the femur (thighbone) is a sharp flange
* fourth trochanter asymmetrical, with distal, lower, margin forming a steeper angle to the shaft
* on the astragalus and calcaneum, upper ankle bones, the proximal articular facet, the top connecting surface, for the fibula occupies less than 30% of the transverse width of the element
* exoccipitals (bones at the back of the skull) do not meet along the midline on the floor of the endocranial cavity, the inner space of the braincase
* in the pelvis, the proximal articular surfaces of the ischium with the ilium and the pubis are separated by a large concave surface (on the upper side of the ischium a part of the open hip joint is located between the contacts with the pubic bone and the ilium)
* cnemial crest on the tibia (protruding part of the top surface of the shinbone) arcs anterolaterally (curves to the front and the outer side)
* distinct proximodistally oriented (vertical) ridge present on the posterior face of the distal end of the tibia (the rear surface of the lower end of the shinbone)
* concave articular surface for the fibula of the calcaneum (the top surface of the calcaneum, where it touches the fibula, has a hollow profile)
Are we meant to believe that separate groups of reptiles which did not originally have these features acquired them through convergent evolution, even though they had widely, wildly different habits of life?
I note that the absence of intermediate forms doesn't bother you one whit in putting forward this extravagant hypothesis. Whereas we do have some. For example, the evolution of ceratopsians from more basal dinosaurs is evidenced in the fossil record. Their evolution from dicynodonts is not. Incidentally, dicynodonts are not, as you claim, archosaurs. They're not even diapsids.

Re: THE GREAT EVOLUTION FOSSIL FAILURE
Unfortunately the existence of "possible precursor life-forms" isn't sufficient to justify a theory like evolution. If these creatures suddenly appear in the fossil record as world conditions change, this rather points to them already being in existence in another location and radiating out from there when world conditions suit them. This appears to be the case with trilobites radiating out from Siberia.
Could I again point out that the paper you referred to was talking about evolutionary radiation and not mere geographical spread.
And could I again ask if we're talking about the same Siberia? Your excuse for the absence of pre-Permian mammals was that they were hidden in Siberia where we can't look. But apparently we can look at pre-Triassic trilobites in Siberia. Which suggests (a) that you're wrong about us not being able to look there and (b) that Siberia was at the time in question underwater.

Re: Intermediates
Before I tackle those skulls in your post, are they in a claimed sequence?
Why would you need to know that?
I would need EVERY claimed detail about those skulls if available. Arm length, skull capacity, scientific name, location, context.
And why would you need to know that? The location? The scientific name? What for? Some of them, say creationists, are total full-on humans, others are absolute apes. Can't you tell an ape from a human?
If you present me with skulls of humans, chimps, gorillas and orangutans, I will be able to tell the humans from the apes with unerring accuracy and without asking any further questions. So why can't you do the same with this equally clear-cut collection of fossils, which, as we know, has nary an intermediate form in it?

Re: THE GREAT EVOLUTION FOSSIL FAILURE
You are obviously referring to Siberian marine areas, but it is indisputable fact that large areas of terrestrial Siberia were covered be flood basalts at the end-Permian.
And, just to be clear about this, the areas that were entirely covered by molten lava happened to be the areas where all the mammals were?
Then why are there mammals?

Haha I'm not trained. In some cases I cannot tell the difference. That is why I would need the full information. But the purpose is not to test my skills, , but to test any legitimacy in a claimed sequence of fossils.
I posted it, I know for what purpose. It's to see how you separate them into apes and humans.

Re: Intermediates
The idea that a bacteria-type common ancestor with 1000 genes can evolve into something with 2000 genes or more is fantasy. A theory with no evidence.
But we can point to many observable instances where the number of genes has increased, e.g. polyploidy, which has been reproduced under lab conditions.

What we have never seen is an invisible wizard poofing organisms into existence by magic. That would be fantasy.
