Fossil Finds Show Cambrian Explosion Getting More Explosive
Cephalopods, which include marine mollusks like squid, octopus, and cuttlefish, are now being reported in the Cambrian explosion fossils. As a recent BBC news article reports: “We go from very simple pre-Cambrian life-forms to something as complex as a cephalopod in the geological blink of an eye, which illustrates just how quickly evolution can produce complexity,” said [evolutionary biologist Martin] Smith. Keep in mind here that “evolution” is a placeholder term for an as-of-yet uncovered mechanism that produces animals like Cephalopods in a “geological blink of an eye.” Darwin’s Dilemma is not solved by vague appeals “how quickly” evolution can operate. All this follows on the heels of recent fossil findings that push phylum Bryozoa back into the Cambrian period, Read More ›
Cambrian Fossils Still a Dilemma for Darwinism 100 Years After Discovery of Burgess Shale
Exactly one hundred years ago leading American paleontologist Charles Doolittle Walcott (right) was hiking along Burgess Pass in the Canadian Rockies when he found a slab of shale containing fossil crustaceans. His interest piqued, Wolcott made return trips to the Burgess Shale in the following years where he ultimately collected tens of thousands of fossils. Many of these fossils were extraordinarily well-preserved, and they were mysterious. They included strange forms like Anomalocaris, Opabinia, Wiwaxia, and Hallucigenia. These fossils revealed a mystery: like other Cambrian fauna, these strange soft-bodied fossils appeared in the fossil record abruptly, without evolutionary precursors. Darwin himself was aware of this problem in his own day, writing that the lack of fossil evidence for the evolution of Read More ›
BioEssays Article Admits “Materialistic Basis of the Cambrian Explosion” is “Elusive”
A recent paper in BioEssays, “MicroRNAs and metazoan macroevolution: insights into canalization, complexity, and the Cambrian explosion,” admits the lack of a “materialistic basis” — that is, a plausible materialistic explanation — of the Cambrian explosion. As the article states: Thus, elucidating the materialistic basis of the Cambrian explosion has become more elusive, not less, the more we know about the event itself, and cannot be explained away by coupling extinction of intermediates with long stretches of geologic time, despite the contrary claims of some modern neo-Darwinists. (Kevin J. Peterson, Michael R. Dietrich and Mark A. McPeek, “MicroRNAs and metazoan macroevolution: insights into canalization, complexity, and the Cambrian explosion,” BioEssays, Vol. 31 (7):736 – 747 (2009).) The authors give no Read More ›
Trails of Microorganisms Discovered on Ocean-Bottom Knock Down Favorite Darwinist Argument Against Cambrian Explosion
A news article at ScienceCentric.com reports that single-celled protists have left tracks and grooves in the ocean-bottom that resemble fossil grooves or “trail” fossils that are found in some pre-Cambrian strata. Darwinists have asserted that such pre-Cambrian track or trail fossils must have been produced by complex, multicellular, worm-like animals, thus implying that the Cambrian explosion was not really as explosive as the fossil record makes it appear. Actual fossils of the alleged pre-Cambrian worms that supposedly made the trails are yet to be found, but Darwinists have claimed that the track fossils are smoking gun evidence that they existed. The Darwinists’ story is challenged by this new find: if tracks can be produced by single-celled protists, then pre-Cambrian track Read More ›
