There is something about catching a hypocrite that I just love....

Yesterday, this forum was graced by a self-appointed (at least via implication) expert on the Cambrian Explosion, and how it is a big problem for evolution. This person's 'expertise' - and condescension - was unleashed on us in a couple of posts:

You could find all major phyla arriving in a period of only 40-50 million years (known as the Cambrian Explosion) utterly destroying the Neo Darwinian gradualism inference.

Did you mean to call attention to the recalcitrant fact of those data, or their knock down capability? Opps. [sic]​


Then:

So you are unfamiliar with the findings since the late 1980s and respond with "50 million years seems like a long tme [sic] to me."

30-seconds of research is all I ask. Not even one college class. It's so simple.

Think we are way past opps [sic] here.​

and finally:

Next item 1st year college student are taught to rely on real research and are not allowed to use wiki as a source due to the fact that it is crowd sourced and not research based.

Given your grasp of the discussion so far I'm dubious of additional complexity but I will spell out why the experts who hold to NeoDarwinian evolution affine the Cambrian explosion to be a potential knockdown argument.

A neo-Darwinian understanding of the mechanism for generating new biological structure generates three specific predictions or empirical expectations concerning the fossil record. Given the operation of the neo-Darwinian mechanism, the fossil record should show: (1) the gradual emergence of biological complexity and the existence of numerous transitional forms leading to new phyla-level body plans; (2) small-scale morphological diversity preceding the emergence of large-scale morphological disparity; and (3) a steady increase in the morphological distance between organic forms over time and, consequently, a steady increase in the number of phyla over time.

None of these three predictions hold.

Now I believe there is good evidence for a 13.7B year old universe, a 4.6B year old earth, and life on this planet staring approximately 3.2-3.5B years ago. I want science to work using an scientific method. What I don't want is scientists using arguments to authority and rhetoric to ofiscate beliefs that are not justified as science.

And I have less tolerance for peoplemwhomdont take the time to do 30 seconds of research and then go out and parrot arguments that have been falsified for 2 -3 decades.​

and for good measure:

Do the research and stop faking it.

No non-sequiturs please. Act like you have had a college class or two.​


A couple of problems....

Where to begin?

How about with the elephant in the room?


You see, dear reader, I have learned from decades of encountering creationists not to trust that their internet forum posts are original. In fact, in my 2 decades or so of this, I have caught probably 100 creationists plagiarizing (4 on this forum alone, and in just the past month or so). And when this creationist's posts went from condescending and insulting to 'coherent', at least for a paragraph, I got suspicious, and in 10 seconds, had the original, un-referenced, unacknowledged source:



http://www.christianity-science.gr/files/CambrianExplosion-Biology'sBigBang.pdf

and, consequently, a steady increase in the number of phyla over time.​


WORD. FOR. WORD.

So this blatant (and repeated) act of plagiarism brings into question some of what the creationist expert had declared.

Let us take a look:

"So you are unfamiliar with the findings since the late 1980s...
30-seconds of research is all I ask. Not even one college class. It's so simple. "

I suppose he is referencing the essay he plagiarized, which came out in 2001.

What has happened since creationist Stephen Meyer wrote the essay in question (along with creationist pals Jon Wells and Paul Chien)?

30 seconds on Google showed me:


Rates of Phenotypic and Genomic Evolution during the Cambrian Explosion
Published Online: September 12, 2013
DOI: Redirecting

"The near-simultaneous appearance of most modern animal body plans (phyla) ∼530 million years ago during the Cambrian explosion is strong evidence for a brief interval of rapid phenotypic and genetic innovation, yet the exact speed and nature of this grand adaptive radiation remain debated [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]. Crucially, rates of morphological evolution in the past (i.e., in ancestral lineages) can be inferred from phenotypic differences among living organisms—just as molecular evolutionary rates in ancestral lineages can be inferred from genetic divergences [13]. ... The fastest inferred rates are still consistent with evolution by natural selection and with data from living organisms, potentially resolving “Darwin’s dilemma.” However, evolution during the Cambrian explosion was unusual (compared to the subsequent Phanerozoic) in that fast rates were present across many lineages."



The Avalon Explosion: Evolution of Ediacara Morphospace
Science 04 Jan 2008:
Vol. 319, Issue 5859, pp. 81-84
DOI: 10.1126/science.1150279

Abstract
Ediacara fossils [575 to 542 million years ago (Ma)] represent Earth's oldest known complex macroscopic life forms, but their morphological history is poorly understood. A comprehensive quantitative analysis of these fossils indicates that the oldest Ediacara assemblage—the Avalon assemblage (575 to 565 Ma)—already encompassed the full range of Ediacara morphospace. A comparable morphospace range was occupied by the subsequent White Sea (560 to 550 Ma) and Nama (550 to 542 Ma) assemblages, although it was populated differently. In contrast, taxonomic richness increased in the White Sea assemblage and declined in the Nama assemblage. These diversity changes, occurring while morphospace range remained relatively constant, led to inverse shifts in morphological variance. The Avalon morphospace expansion mirrors the Cambrian explosion, and both events may reflect similar underlying mechanisms.



There were many, many more, but a couple prove my point - somebody is behind the times, but not who is implied by our new expert.

But wait - there is more!


Our expert condescends:

"Given your grasp of the discussion so far I'm dubious of additional complexity but I will spell out why..."

Get that?

"I will..."

followed by a copy-pasted, un-referenced, un-cited paragraph of someone else's work.

And it gets even better:


"What I don't want is scientists using arguments to authority and rhetoric to ofiscate [sic] beliefs that are not justified as science."


I would say that plagiarizing Meyer constitutes an appeal to authority?


"And I have less tolerance for peoplemwhomdont take the time to do 30 seconds of research and then go out and parrot arguments that have been falsified for 2 -3 decades. "


See above.



Folks, nothing to see here. Just more plagiarism and bombast.

And I won't even mention that referring to the "predictions" of evolution as portrayed by 3 CREATIONISTS who set out to 'disprove' evolution (odd that they NEVER seem to do 'research' that would support ID or creationism, isn't it?) is specious, at best.

The op never tires of propaganda. Instead of engaging the Cambrian explosion as 30 years of disconfirmatory evidence for the gradualism inferences in NeoDarwinian theory we are treated to red herring, non-sequiturs and hand waving, proving a reliance on rhetoric rather than scientific method.

No explanation will be given by the OP for the data. This doesn't mean that the theory of evolution broadly construed is false, rather that the Darwinian and NeoDarwinian models that produces such lovely trees of life are in fact parallel vertical branches. Instead of searching for an explanation as a scientist we are treated with wave upon wave of propaganda.

While 30 to 50 million years is a relative short period of time when compared to the 14 billion years or so that the universe has been around, for the purposes of evolution I think that the term 'explosion' confuses to some people. It's one heck of a long time to us and and something that we can barely imagine. It is more than sufficient time period for evolution to occur.

What? What evidence disconfirms evolution? Also, what 'red herrings, non-sequiturs and hand waving' could you point out for us that isn't yours?

Are you serious? What explanation for what data? Please give examples, don't be light on details now...Feel free to point out where these 'parallel vertical branches' end and the branching tree of life begin. Also, it seems to me that you are conflating 'propaganda' and peer reviewed scientific research that scientists 'searching for an explanation' have already done.

Says the guy who copy pastes sciency-sounding paragraphes from creationist propaganda and fails to cite his sources, pretending/implying that the material is the result of his own "expertise".

You just lost all credibility, dude, I'm sorry to say.

You've been caught red-handed. Projection is not going to save you here.

The hubris is amazing - almost as amazing as the typical creationist projection.

One will note that the plagiarist did not even try to address the cited papers, just spewed nonsense in a continual farce, pretending to possess knowledge that the creationist thinks copy-pastes demonstrate.

Sad.

Well, really, while the cambrian explosion may at large have occurred over 40-50 million years, you still even have the buildup of the fossil succession, another 100 million years prior to that with micro shellies, the first shelled organisms and the ediacaran.

You also get the explosion occurring in conjunction with the rifting of rodinia and the ending of snowball earth, with further increase of shallow marine environments around the rifting and warming landmass.

You also have your biological arms race.

In short, I think young earthers are still a good 50-100 years behind on their research and are still arguing from age old positions that are long settled.

I've been clicking on the "List" to see who thinks this is a winning post. The link doesn't work. And it's the only link on the page that seems broken. Is that meaningful? :oldthumbsup:

It's working for me now, too. It was just funny that the only link I couldn't get to work was the one where somebody thinks Uber's post is a winner. As if....

Interesting that the ultimate plagiarizing authority never did condescend to us all to EXPLAIN how his plagiarized paragraph had the effect he claimed.

But so cute how even Uber has groupies....

OK, I like to see the "pre-trilobite" before the Cambrian Explosion. Do we have that.

Any similar case would be fine.

The Timetree of Life
Encyclopedia of Evolutionary Biology

the bodies themselves do not fossilize as they do not have shells, but their traces/footprints, go back prior to the cambrian explosion into what is the nemakitdaldynian. Whereas the bodies of trilobites appear some 10 million years after their footprints appear. Because they developed shells.

The traces are known as rusophycus and cruziana.

There are also bilobate rest marks of tiny trilobite like arthropods as well.
-------------------------
To further expound,

we constantly hear young earthers say well, everything just instantaneously appeared. But thats just not true. Further, there are small mollusks, bivalves, worms, corals, and other microscopic organisms that predate the cambrian explosion. Not including the ediacaran biota.

But the thing is, the older you go back in time, the more recycled the rock is, the smaller the animals are, and the less shelled material they have. And they and their tracks, fade away through time.

The cambrian explosion is considered to be an evolutionary arms race, it was an exponential development of animals, but it certainly was not some instantaneous appearance of everything. And this arms race, further occurred in conjunction with geologic events such as the rifting of rodinia and the end of a great ice age, which have been proposed as possible explanations for its occurrence.

And its rare that i can say this, but because the opportunity is here, I will. I actually have published research on early trilobites, arthropods and their trace marks, so while im not a crazy expert on that area of research, I'd like to think that I know a little bit about it.

The overall point is, the explosion wasnt instantaneous.

From no shell to have shell. Do we expect to see something in the middle?

Thats a good question. I'm not sure that we would. Something in the middle might be something like a soft shell, or a fragmented or incomplete shell. Both would probably be difficult to find or to even identify or to understand.

Anomalocaris is a pretty popular ancient fossil. It actually has hard parts and soft parts. And the hard parts were found first (because they fossilize easier and are just more prominant), but it wasnt known that they were part of a soft bodied animal until later when a complete soft bodied anomalocaris was found (with its hard parts included). And soft bodied anomalocaris, complete fossils are very rare to find. so rare that, really you could count the total number of them ever discovered possibly with fingers of a single hand, maybe 2 hands. So, even if we did find partial hard or calcified animals, we might not even know it because the animals from back then are so bizarre and abstract at times, that its hard to know what is even being looked at without finding multiple specimen.

Fossils post cambrian are much easier to understand, than fossils of the precambrian, or pre-cambrian explosion. With the cambrian, you just keep going back and back and back, until eventually evidence disappears. And its likely because you look so far back into history that the rocks are digested in the bowels of the earth, and that destroys fossils, and the organisms, you dont find things like giant dinosaurs in the cambrian. Many cambrian fossils are really small like maybe a few centimers in length, or maybe you might get something that is a foot or 2, but in large part the animals are tiny. And not only are they tiny but they are soft bodied.

And beyond that further, you get micro-shellies. Things like claudina
Cloudinidae - Wikipedia

Beyond that what would be next? microscopic soft bodied fossils? Eventually it has to stop somewhere, somewhere you are inevitably going to run out of evidence. And this is where it happens.

Yes, it is a problem. We do not have a modern analogy to it, so we do not even know what to think. That is why the Cambrian explosion is called an explosion. I think the term makes sense. Something big happened across the boundary, no matter how long is the time of the boundary.
