A friend asks a bunch of us if we are as incredulous of Darwinist attempts to explain away the Cambrian explosion as he is. Well, I always say, try me on some of the latest nonsense, and he did. It is conveniently here, in relation to the Dengying fossils in southern China (541 to 551 million years ago):

The first instance of biomineralization – i.e. the biologic use of minerals – was around 2 billion years ago when certain bacteria precipitated grains of magnetite to apparently help orient themselves in the Earth’s magnetic field. However, the first animal skeletons didn’t appear until right before the Cambrian explosion, at the end of the Ediacaran Period.These early shell-bearing creatures help to resolve Charles Darwin’s concern over the sudden appearance of so many new animal species during the Cambrian explosion. The fossil record gives the impression of a “Creation” event, but in reality, animals had evolved prior to the explosion. They just didn’t leave much for paleontologists to find until they developed the skeleton-making trait.

Reminded me of something:

The first time anyone wondered about thefts from the liquor store was on March 22, when a couple of guys appeared to be loitering with intent. However, the first theft of cash and cases of liquor didn’t occur until June 29, at the end of the subsequent accounting period.This reported theft helps to resolve management’s concern over the sudden disappearance of so much cash and so many cases during the night of June 29. The inventory record gives the impression of a major theft, but in reality, lots of cash and cases had gone missing prior to the reported heist. They just didn’t leave much for investigators to find because they weren’t logged into inventory in the first place.

Hardline Darwinists obviously fear the Cambrian explosion the way crooks fear an honest investigator. You can play their claim game yourself:

The first __________ was on/around ___________ when ______________. However, the first __________ didn’t ___________ until _____________________.This ___________ helps to resolve ____________’s concern over the sudden ________ of so many __________ during the ___________. The _________ record gives the impression of a __________, but in reality, ____________. They just didn’t leave much for ___________ to find because they (in some way, you make it up, couldn’t be traced) ________________.

I guess in the world of Darwin, that counts for an explanation.

So all of the animals slowly evolved, but without skeletons. Then they all evolved skeletons at the same time. Problem solved!Collin_{January 8, 2011

further note: Macroscopic life in the Palaeoproterozoic - July 2010 Excerpt: The Ediacaran fauna shows that soft-bodied animals were preserved in the Precambrian, even in coarse sandstone beds, suggesting that (the hypothetical transitional) fossils are not found because they were not there. http://www.arn.org/blogs/index.php/literature/2010/07/02/macroscopic_life_in_the_palaeoproterozoi 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."

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." http://www.discovery.org/a/12471 Deepening Darwin's Dilemma - Jonathan Wells - The Cambrian Explosion - video http://www.metacafe.com/watch/4154263 Interestingly, Jellyfish and Sponges are 'soft-bodied; and appeared suddenly in the fossil record a few ten million years before the Cambrian Explosion, and have remained virtually unchanged since they first appeared in the fossil record. Moreover, contrary to evolutionary thinking, Jellyfish and Sponges appear to have essential purpose in preparing the ecosystem for the Cambrian Explosion that was to follow. Marine animals cause a stir - July 2009 Excerpt: Kakani Katija and John Dabiri used field measurements of jellyfish swimming in a remote island lake, combined with a new theoretical model, to demonstrate that the contribution of living organisms to ocean mixing via this mechanism is substantial — of the same order of magnitude as winds and tides. (Winds and tides, due to their prevention of stagnation, are known to be essential for life on earth.) http://www.nature.com/nature/journal/v460/n7255/edsumm/e090730-08.html Sponges Determine Coral Reef's Nutrient Cycle Excerpt: Sponges, which have worldwide distribution in the oceans, filter water. They take up planktonic particles such as bacteria and excrete inorganic nutrients. In turn, these nutrients can facilitate the growth of marine plants and other organisms. Sponges filter water at a phenomenal rate: if the seawater were to remain stationary, the sponges would have completely pumped it away within five minutes,,,, these organisms play a key role in the marine nutrient cycle due to their incredible capacity to convert enormous quantities of organic plankton into inorganic material (nutrients). http://www.sciencedaily.com/releases/2005/09/050917085649.htm Fossils of all types of sponges alive today have been found virtually unchanged in rocks dated from 635 to 580 million years ago. Moreover, sponges with photosynthesizing endosymbionts produce up to three times more oxygen than they consume, as well as more organic matter than they consume (Wikipedia). Barrel and Chimney Sponges Filtering Water - video http://www.youtube.com/watch?v=T7E1rq7zHLc The mysterious Ediacara biota, which appeared abruptly, alongside the Sponges and Jellyfish, in the pre-Cambrian fossil record, and which defy classification as either plant or animal, much less classification of essential symbiotic purpose, largely disappeared from the fossil record a few million years before the Cambrian Explosion and thus are not seen to be viable as precursors to the Cambrian Explosion. The Avalon Explosion: Excerpt: Ediacara fossils [575 to 542 million years ago (Ma)] represent Earth's oldest known complex macroscopic life forms,,, 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. (i.e. they appeared abruptly in the fossil record and retained their same basic shape and form throughout their tenure in the fossil record before they went extinct prior to the Cambrian explosion.) http://www.sciencemag.org/cgi/content/abstract/319/5859/81 My hunch is that, as with photosynthetic bacteria, sulfate reducing bacteria, sponges, and jellyfish, Ediacara biota will ultimately be found to have a essential biogeochemical role in preparing the earth for more advanced life to appear in the Cambrian explosion. This following paper, although evolutionary in its basis, offers a few tantalizing clues as to what that essential purpose for Ediacara biota might have been. The mysterious Ediacara biota: Excerpt: "many questions remain. In particular, we might consider why the earliest known Ediacarans thrived in a deep ocean setting, when the oxygen apparently so vital for their evolution had already been abundant in shallow marine environments for millions of years." http://www.nerc.ac.uk/publications/planetearth/2008/spring/spr08-animals.pdf This following study adds weight to my guess that the mysterious Ediacara biota were essential for detoxifying the deep ocean: You Mean There Really Was a Cambrian Explosion? - June 21 2010 Excerpt: Using novel geochemical techniques developed by Newcastle University’s Dr Simon Poulton, the team found that beneath oxygenated surface waters, mid-depth oceanic waters were rich in sulphide about 1.8 billion years ago, conditions that may have persisted until oxygenation of the deep ocean more than 1 billion years later. These widespread sulphidic conditions close to the continents, coupled with deeper waters that remained oxygen-free and iron-rich, would have placed major restrictions on both the timing and pace of biological evolution. Dr Poulton, who led the research, explained: “It has traditionally been assumed that the first rise in atmospheric oxygen eventually led to oxygenation of the deep ocean around 1.8 billion years ago. “This assumption has been called into question over recent years, and here we show that the ocean remained oxygen-free but became rich in toxic hydrogen-sulphide over an area that extended more than 100 km from the continents. It took a second major rise in atmospheric oxygen around 580 million years ago to oxygenate the deep ocean. https://uncommondescent.com/intelligent-design/you-mean-there-really-was-a-cambrian-explosion/bornagain77_{January 8, 2011
