I'm honored.

could indicate it was improbable or it could mean the things we seek never did exist, how can you tell?
By reading a book on taphonomy. If you're
actually claiming that fossilization isn't an improbable event, you should probably support your claim.
I don't see how reading a book serves as evidence that fossilization was rare. Said rarity is an interpretation of what we find, another interpretation is that it was not as rare as claimed and the lack of ancestral fossils ia a real absence of things to fossilze.
The claim is that ancestral forms existed (for example the ancestry of Anoamlocaris) why should I believe these ancestors did exist when there's absolutely no fossile evidence for them?
Why is my suggestion that the absence of ancestor fossils might be due to an absence of ancestors any more needy of evidence than the claim fossilization was rare?

Sherlock Holmes wrote: ↑Sun Jan 02, 2022 2:03 pm2. Fossils of soft bodied primitive life are well known and common in places like Cheng-Jiang, in strata that immediately precedes early complex Cambrian life, no trace whatsoever has ever been found of presumed transitionals.
They're "common" under a limited number of conditions, which is evidenced by the fact that you can specify one particular location and we know what you're talking about (Burgess Shale formation, anyone?). If, on the other hand, you're claiming that such conditions are common in general, you should probably support your claim.
The point is that one cannot infer that conditions are the reason we find no Cambrian ancestors when there are places where conditions can be seen to have been superb by fossilizing ameobas and other soft tiny organisms yet curiously non of the claimed ancestors ofr any of the complex large Cambrian fauna.
Why were no Cambrian ancestors fossilized in Cheng-Jiang when we can see that preservation conditions were so good that tiny soft organisms were fossilized en-mass?
Whereever we have found Cambrian fossils we also find the same absence of ancestors, the pattern is that ancestors are never found anywhere that's evidence of absence I think.

Since you haven't actually supported any of your own claims yet, I don't think we're to the point in the discussion where we question the opinions of experts. Since I've only provided generic support for my own so far, a similar bar shouldn't be difficult for you to clear yourself. One step at a time.
What "claim"? that the Cambrian explosion reveals an abrupt, sudden appearance of complex life? That is not my claim, this is what paleontologists say! it is they who refer to it as the Cambrian "explosion". They would not refer to it that way if the evidence of ancestors was prevalant, but it isn't.
Now I don't "claim" that the there were no ancestors but I do argue that such a claim is consistent with the evidence, and one is being reasonable to rergard the claim that there were hundreds of thousands of generations that just somehow never ever every got fossilized as rather a stretch.

Are you actually making a claim that they don't and will now support it? Or is this still
"just asking questions?"
No I asked for examples of fossils that demonstrate an evolutionary link between disparate organisms. If you have fossil evidence that proves such a linkage may I see it please?

This is a shifting of the goal posts and a
non sequitur. Your (still unsupported) claim was that fossilization is discontinuous, not that we are exclusively discussing the Cambrian.
The fossil record is discontinuous.
Difflugia wrote: ↑Sun Jan 02, 2022 3:18 pm
Even if we are, though, molecular data provide enough resolution that we can infer ancestry back at least to the origin of eukaryotes themselves, which predates the Cambrian. You could, of course, dispute that, but you should probably support your own positions first if you intend to play fair.
Only if one assumes evolution was at work. You cant use an argument based on the assumption live evolved as support for the argument life evolved.

Sherlock Holmes wrote: ↑Sun Jan 02, 2022 2:03 pm6. The "branching diagram" is not evidence, it is an
interpretation of evidence.
For a particularly broad definition of "interpretation," that's true, but by that definition, even the term "discontinuous" would be an "interpretation" rather than the evidence that you claim it is.
Yes I agree, I totally agree that the discontinuity is an interetation of what we observe.
Difflugia wrote: ↑Sun Jan 02, 2022 3:18 pm
The ability to place the data in trees that are consistent with alternate choices of characters as well as molecular data is itself evidence that evolution is continuous.
These trees may not have existed though, the "branches" linking distinct organisms might never have existed, they are presumed because evolution is presumed. The trees are a statement about definite relationships, parent/child relationships that are not observed, only inferred.
Difflugia wrote: ↑Sun Jan 02, 2022 3:18 pm
As an example, if any organisms had the combination of hair, mammary glands, feathers, and septate lungs, then its placement in the tree with mammals or birds would depend on which characters were selected. We don't see such combinations in real life.
And of what of that? how does not finding some arbitrary set of features in a single organism serve to support evolution?
Let me say again - the fossil record - falsifies evolution, it is not what a reasonable person would expect to find if evolution were true. The organisms that are missing are always the same organisms no matter where we find Cambrian fossils we also note that the missing things are also missing in every other place we find Cambrian fossils. Darwin was extremely unhappy about this and nothing has been found since then to clear this up.

Sherlock Holmes wrote: ↑Sun Jan 02, 2022 2:03 pmThere are of course many books like the one you cite, I've got some of them myself, but they primarily interpret evidence, they seek out areas of perceived consistency and brush aside, downplay area of inconsistency, the reason is the authors already "know" evolution took place and so evidence in support is embraced and evidence that's counter can be ignored because we know evolution is true so these cases do not matter.
Then you should easily be able to support this unsupported claim. It is "of course" false.
Sherlock Holmes wrote: ↑Sun Jan 02, 2022 2:03 pmReferring to me as an "uninformed creationist" or that a textbook on the subject is "incredibly novel" to me are ad-hominem attacks and have no place in our discussion.
Are you proposing that neither of us engages in rhetorical
ad hominem quips anymore? That's fine. Or are you indulging in a bit of
chutzpah by implying that your own responses have been lacking them?
I'm asking for politeness rather than dispraging wordplay which serves to discredit me by association.
Focus on falsification, if evolution is falsified then it matters not what other areas we can use to salvage it, falisfication is the death knell of any theory.
Just type this into Google "is the fossil record discontinuous".
