Cambrian explosion extinction News

So the Cambrian really was an explosion then?

Spread the love

The preceding Ediacaran life forms (635 to 542 mya) were gone already? Eaten up by early Cambrians (542 to 513 mya)?

From New Scientist:

The disappearance of the Ediacarans from the fossil record has long troubled biologists. Leading theories are a catastrophic mass extinction, that Ediacarans got eaten or had their habitat destroyed by newly evolved animals, or no longer left fossils because of a change in ocean conditions.

But a careful search by Marc Laflamme of the University of Toronto in Mississauga and colleagues threw up no geochemical signatures of low-oxygen conditions or other turmoil to support the idea of an environmentally driven mass extinction. And given that soft-bodied Cambrian animals are fossilised within rocks like the famed Burgess Shale, it seems unlikely that the conditions simply didn’t allow any surviving Edicaranas to leave a fossil trace in the Cambrian period.

That suggests that by the time the Cambrian explosion of species reached full force, the Ediacarans were gone

According to this interesting thesis, the early Cambrians simply ate up the Ediacarans within a few million years:

But he adds that although many of those Ediacarans were so strange that their biology makes little sense to us today, there is evidence that some of them did evolve movement and ways of ingesting food like modern animals, so may have given rise to life forms that evolved later. More.

So there was little of the Ediacarans left after the Cambrians gobbled them up, and then exploded, in numbers and type, as Steve Meyer has argued:

Imagine, Meyer’s Darwin’s Doubt is doing better in paleontology than in creationism.

    A better hypothesis, IMO, is that the explosion-extinction events observed in the fossil record were part of a carefully orchestrated plan by advanced lifeforms to terraform the planet.

    Do the math, Seversky. Thirty million is an eyeblink for that many phyla. Fine Tuning & Design no mistake. Obvious. Do the math. Be scientific.

    Darwin was a math spazz and even he had doubts about his theory and the Cambrian. “Well, they probably WILL find fossils someday” he argued. Sorry Charlie, nope.

    How about the phyla that ate all the fossils and then ate eachother. No fossils of them either. Checkmate IDiots.

    Undead: The Myth of the 80-Million-Year Cambrian Explosion – November 13, 2013
    Excerpt: the trick is premised on “including as part of the Cambrian explosion (a) the origin of the Ediacaran organisms in the late Precambrian (which no serious scientist considers to be ancestral to the Cambrian animals), and (b) the small shelly fossils at the base of the Cambrian and (c) the main pulse of morphological innovation in the early Cambrian, and (d) subsequent diversification events right up until the end of the Cambrian period.”,,, – Meyer notes that Marshall himself elsewhere excludes the precious small shellies.,,,-

    ,,,, the simple fact of the matter is that the fossil record itself refuses to cooperate with your gradualistic druthers. The fossils of major groups, i.e. phyla, simply appear suddenly in the fossil record with no discernible ancestral forms:

    A Graduate Student (Nick Matzke) Writes – David Berlinski July 9, 2013
    Excerpt: Representatives of twenty-three of the roughly twenty-seven fossilized animal phyla, and the roughly thirty-six animal phyla overall, are present in the Cambrian fossil record. Twenty of these twenty-three major groups make their appearance with no discernible ancestral forms in either earlier Cambrian or Precambrian strata. Representatives of the remaining three or so animal phyla originate in the late Precambrian, but they do so as abruptly as the animals that appeared first in Cambrian. Moreover, these late Precambrian animals lack clear affinities with the representatives of the twenty or so phyla that first appear in the Cambrian.

    Deepening Darwin’s Dilemma – Jonathan Wells – Sept. 2009
    Excerpt: “The truth is that (finding) “exceptionally preserved microbes” from the late Precambrian actually deepen Darwin’s dilemma, because they suggest that if there had been ancestors to the Cambrian phyla they would have been preserved.”

    Ediacaran embryos in retrospect – David Tyler – January 28, 2013
    Excerpt: “there is currently no convincing evidence for advanced animals with bilateral symmetry in the Doushantuo biota”. This particular quest for animals preceding the Cambrian Explosion has drawn a blank. Needless to say, Darwin’s dilemma remains in full force.

    In fact, completely contrary to Darwinian thought, the fossils of the Cambrian reveal a ‘top down’ pattern of appearance, instead of the ‘bottom up’ pattern envisioned by Darwin. Darwin predicted that minor differences (diversity) between species would gradually appear first and then the differences would grow larger (disparity) between species as time went on. i.e. universal common descent as depicted in Darwin’s tree of life. What Darwin predicted should be familiar to everyone and is easily represented in the following graph.,,,

    The Theory – Diversity precedes Disparity – graph

    But that ‘tree pattern’ that Darwin predicted is not what is found in the fossil record. The fossil record reveals that disparity (the greatest differences) precedes diversity (the smaller differences), which is the exact opposite pattern for what Darwin’s theory predicted.

    Timeline graphic on Cambrian Explosion from ‘Darwin’s Doubt’ (Disparity preceding Diversity)

    “Darwin had a lot of trouble with the fossil record because if you look at the record of phyla in the rocks as fossils why when they first appear we already see them all. The phyla are fully formed. It’s as if the phyla were created first and they were modified into classes and we see that the number of classes peak later than the number of phyla and the number of orders peak later than that. So it’s kind of a top down succession, you start with this basic body plans, the phyla, and you diversify them into classes, the major sub-divisions of the phyla, and these into orders and so on. So the fossil record is kind of backwards from what you would expect from in that sense from what you would expect from Darwin’s ideas.”
    James W. Valentine – as quoted from “On the Origin of Phyla: Interviews with James W. Valentine” – (as stated at 1:16:36 mark of video)

    Moreover, there are ‘yawning chasms’ in the ‘morphological space’ between the phyla which suddenly appeared in the Cambrian Explosion,,,

    “Over the past 150 years or so, paleontologists have found many representatives of the phyla that were well-known in Darwin’s time (by analogy, the equivalent of the three primary colors) and a few completely new forms altogether (by analogy, some other distinct colors such as green and orange, perhaps). And, of course, within these phyla, there is a great deal of variety. Nevertheless, the analogy holds at least insofar as the differences in form between any member of one phylum and any member of another phylum are vast, and paleontologists have utterly failed to find forms that would fill these yawning chasms in what biotechnologists call “morphological space.” In other words, they have failed to find the paleolontogical equivalent of the numerous finely graded intermediate colors (Oedleton blue, dusty rose, gun barrel gray, magenta, etc.) that interior designers covet. Instead, extensive sampling of the fossil record has confirmed a strikingly discontinuous pattern in which representatives of the major phyla stand in stark isolation from members of other phyla, without intermediate forms filling the intervening morphological space.”
    Stephen Meyer – Darwin’s Doubt (p. 70)

    Moreover, this top down pattern in the fossil record, which is the complete opposite pattern as Darwin predicted for the fossil record, is not only found in the Cambrian Explosion, but this ‘top down’, disparity preceding diversity, pattern is found in the fossil record subsequent to the Cambrian explosion as well.

    Scientific study turns understanding about evolution on its head – July 30, 2013
    Excerpt: evolutionary biologists,,, looked at nearly one hundred fossil groups to test the notion that it takes groups of animals many millions of years to reach their maximum diversity of form.
    Contrary to popular belief, not all animal groups continued to evolve fundamentally new morphologies through time. The majority actually achieved their greatest diversity of form (disparity) relatively early in their histories.
    ,,,Dr Matthew Wills said: “This pattern, known as ‘early high disparity’, turns the traditional V-shaped cone model of evolution on its head. What is equally surprising in our findings is that groups of animals are likely to show early-high disparity regardless of when they originated over the last half a billion years. This isn’t a phenomenon particularly associated with the first radiation of animals (in the Cambrian Explosion), or periods in the immediate wake of mass extinctions.”,,,
    Author Martin Hughes, continued: “Our work implies that there must be constraints on the range of forms within animal groups, and that these limits are often hit relatively early on.
    Co-author Dr Sylvain Gerber, added: “A key question now is what prevents groups from generating fundamentally new forms later on in their evolution.,,,

    “In virtually all cases a new taxon appears for the first time in the fossil record with most definitive features already present, and practically no known stem-group forms.”
    TS Kemp – Fossils and Evolution,– Curator of Zoological Collections, Oxford University, Oxford Uni Press, p246, 1999

    “What is missing are the many intermediate forms hypothesized by Darwin, and the continual divergence of major lineages into the morphospace between distinct adaptive types.”
    Robert L Carroll (born 1938) – vertebrate paleontologist who specialises in Paleozoic and Mesozoic amphibians

    Moreover Seversky, time is not your friend. Even is you had all the time in the universe, Darwinian evolution is still impossible:

    Waiting Longer for Two Mutations – Michael J. Behe
    Excerpt: Citing malaria literature sources (White 2004) I had noted that the de novo appearance of chloroquine resistance in Plasmodium falciparum was an event of probability of 1 in 10^20. I then wrote that ‘for humans to achieve a mutation like this by chance, we would have to wait 100 million times 10 million years’ (1 quadrillion years)(Behe 2007) (because that is the extrapolated time that it would take to produce 10^20 humans). Durrett and Schmidt (2008, p. 1507) retort that my number ‘is 5 million times larger than the calculation we have just given’ using their model (which nonetheless “using their model” gives a prohibitively long waiting time of 216 million years). Their criticism compares apples to oranges. My figure of 10^20 is an empirical statistic from the literature; it is not, as their calculation is, a theoretical estimate from a population genetics model.

    “Shared Evolutionary History or Shared Design?” – Ann Gauger – January 1, 2015
    Excerpt: The waiting time required to achieve four mutations is 10^15 years. That’s longer than the age of the universe. The real waiting time is likely to be much greater, since the two most likely candidate enzymes failed to be coopted by double mutations.

    When Theory and Experiment Collide — April 16th, 2011 by Douglas Axe
    Excerpt: Based on our experimental observations and on calculations we made using a published population model [3], we estimated that Darwin’s mechanism would need a truly staggering amount of time—a trillion trillion years or more—to accomplish the seemingly subtle change in enzyme function that we studied.

    In fact, if Darwinists were ever consistent in their thinking, they would honestly admit that adding more time only worsens the problem for them:

    Time: The Unlikely Villain
    Excerpt: When confronted with the problem of equilibrium, most scientific materialists will appeal to the magic ingredient of time. In chapter one we saw this appeal by Nobel Laureate, George Wald:
    “Time is in fact the hero of the plot. Given so much time the impossible becomes possible, the possible probable, and the probable virtually certain. One has only to wait: Time itself performs the miracles.” 49
    However, Dr. (Harold F.) Blum, who is a materialist, points out that Wald’s faith in the miraculous ingredient of time is mere wishful thinking. Prolonged time periods, he asserts, actually worsen the dilemma:
    “I think if I were rewriting this chapter [on the origin of life] completely, I should want to change the emphasis somewhat. I should want to play down still more the importance of the great amount of time available for highly improbable events to occur. One may take the view that the greater the time elapsed the greater should be the approach to equilibrium, the most probable state, and it seems that this ought to take precedence in our thinking over the idea that time provides the possibility for the occurrence of the highly improbable.” 50 (Emphasis added)
    According to Dr. Blum, the magic bullet of time does not increase the likelihood that chains of DNA or proteins will form by chance chemistry. In fact, according to Dr. Blum, increasing the time factor actually ensures that any primordial soup would consist of predominantly unbonded amino acids and nucleotides!

    Of supplemental note: Since space-time, along with the entire material universe, was suddenly created in the Big Bang then, scientifically speaking, there is no scientific reason why anything within the universe, such as the animal body plans of the Cambrian, cannot also appear suddenly within the universe.
    In fact, the fact that we do not observe stuff popping into, and out of, existence is strong disconfirming evidence for the multiverse hypothesis of atheists, (which they postulated to ‘explain away’ the fine-tuning of the universe.)

    Multiverse and the Design Argument – William Lane Craig
    Excerpt: Roger Penrose of Oxford University has calculated that the odds of our universe’s low entropy condition obtaining by chance alone are on the order of 1 in 10^10(123), an inconceivable number. If our universe were but one member of a multiverse of randomly ordered worlds, then it is vastly more probable that we should be observing a much smaller universe. For example, the odds of our solar system’s being formed instantly by the random collision of particles is about 1 in 10^10(60), a vast number, but inconceivably smaller than 1 in 10^10(123). (Penrose calls it “utter chicken feed” by comparison [The Road to Reality (Knopf, 2005), pp. 762-5]). Or again, if our universe is but one member of a multiverse, then we ought to be observing highly extraordinary events, like horses’ popping into and out of existence by random collisions, or perpetual motion machines, since these are vastly more probable than all of nature’s constants and quantities’ falling by chance into the virtually infinitesimal life-permitting range. Observable universes like those strange worlds are simply much more plenteous in the ensemble of universes than worlds like ours and, therefore, ought to be observed by us if the universe were but a random member of a multiverse of worlds. Since we do not have such observations, that fact strongly disconfirms the multiverse hypothesis. On naturalism, at least, it is therefore highly probable that there is no multiverse. — Penrose puts it bluntly “these world ensemble hypothesis are worse than useless in explaining the anthropic fine-tuning of the universe”.

    Of reated note to time: Imagine moving away from the face of a clock at the speed of light. Would not the hands on the clock stay stationary as you moved away from the face of the clock at the speed of light? Moving away from the face of a clock at the speed of light happens to be the same ‘thought experiment’ that gave Einstein his breakthrough insight into e=mc2.

    Albert Einstein – The Einstein Factor – Reader’s Digest – 2005

    “The laws of relativity have changed timeless existence from a theological claim to a physical reality. Light, you see, is outside of time, a fact of nature proven in thousands of experiments at hundreds of universities. I don’t pretend to know how tomorrow can exist simultaneously with today and yesterday. But at the speed of light they actually and rigorously do. Time does not pass.”
