“Unfossilizable” fossils found, from late Cambrian, show early specialization

And considered “remarkable” for exploring a specialized niche so early in their evolution. From ScienceDaily:

Loriciferans are a group of miniscule animals, always less than a millimetre long, which live among grains of sediment on the seabed. They are easy to overlook: the first examples were described from modern environments as recently as the 1980s.

Dr Harvey added: “As well as being very small, loriciferans lack hard parts (they have no shell), so no-one expected them ever to be found as fossils — but here they are! The fossils represent a new genus and species, which we name Eolorica deadwoodensis, loosely meaning the “ancient corset-animal from rocks of the Deadwood Formation.”

“It’s remarkable that so early in their evolution, animals were already exploiting such specialized meiobenthic ecologies: shrinking their bodies down to the size of single-celled organisms, and living among grains of sediment on the seabed.” Paper. (public access) – Thomas H. P. Harvey, Nicholas J. Butterfield. Exceptionally preserved Cambrian loriciferans and the early animal invasion of the meiobenthos. Nature Ecology & Evolution, 2017; 1: 0022 DOI: 10.1038/s41559-016-0022 More.

But how did we decide that early specialization is “remarkable”? Doesn’t that assume a Darwinian daily, hourly adding up? An adding up that never seems to happen quite that way?

Why isn’t the fact that life so seldom develops that way up for honest discussion? As opposed to a few reliable toffs being allowed to air mild objections to the “narrative” now and then. And then it just gets repeated with no change.

And then the whole thing gets shelved, of course, so that fourth rate tax burdens (lecturers) can go on lecturing in peace. What the public doesn’t know won’t hurt, right?

    Response to John Wise – October 2010
    “So, where then are those ancestors? Fossil preservation conditions were adequate to preserve animals such as jellyfish, corals, and sponges, as well as the Ediacaran fauna. It does not appear that scarcity is a fault of the fossil record.”

    “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.”

    Excerpt: “In other words, the morphological distances — gaps — between body plans of crown phyla were present when body fossils first appeared during the explosion and have been with us ever since. The morphological disparity is so great between most phyla that the homologous reference points or landmarks required for quantitative studies of morphology are absent.”

    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 Allaying Darwin’s Doubt, Two Cambrian Experts Still Come Up Short – October 16, 2015
    Excerpt: “A recent analysis of disparity in 98 metazoan clades through the Phanerozoic found a preponderance of clades with maximal disparity early in their history. Thus, whether or not taxonomic diversification slows down most studies of disparity reveal a pattern in which the early evolution of a clade defines the morphological boundaries of a group which are then filled in by subsequent diversification. This pattern is inconsistent with that expected of a classic adaptive radiation in which diversity and disparity should be coupled, at least during the early phase of the radiation.”
    – Doug Erwin
    What this admits is that disparity is a worse problem than evolutionists had realized: it’s ubiquitous (throughout the history of life on earth), not just in the Cambrian (Explosion).

    earlier useful complexity/information than expected under NDT doctrine not only attests to ID but aligns better with YeC than Deep-time doctrine dogma tenants.
