What is the best explanation for the Cambrian fossil record?

i found an interesting video that explores a mystery in the Cambrian fossil record.

Richard Dawkins explains the mystery in his famous book “The Blind Watchmaker”.

Excerpt:

“Eldredge and Gould certainly would agree that some very important gaps really are due to imperfections in the fossil record. Very big gaps, too. For example the Cambrian strata of rocks, vintage about 600 million years, are the oldest ones in which we find most of the major invertebrate groups. And we find many of them already in an advanced state of evolution, the very first time they appear. It is as though they were just planted there, without any evolutionary history.” (Dawkins, Richard [zoologist and Professor for the Public Understanding of Science, Oxford University], “The Blind Watchmaker,” [1986], Penguin: London, 1991, reprint, p.229)

He’s referring to prominent paleontologists Niles Eldredge and Stephen Jay Gould.

Now let’s watch the video.

Part 2 of 2: (33 minutes)

This documentary has a mix of scholars who accept the standard naturalistic explanation for the Cambrian explosion, and some who are skeptical of the standard explanation. The first three scholars in the list below are considered to be world-renown experts in the Cambrian era fossils.

List of scholars:

Simon Conway Morris is Professor of Palaeobiology at the University of Cambridge and one of the world’s leading evolutionary paleontologists. He is noted in particular for his contributions to the understanding of the Cambrian Explosion and the fossils found in the Burgess Shale. Elected as a Fellow of the Royal Society (United Kingdom) in 1990, he also has been awarded the Walcott Medal of the National Academy of Sciences (United States). Dr. Conway Morris is author of the noted books The Crucible of Creation: The Burgess Shale and the Rise of Animals (1998) and Life’s Solution: Inevitable Humans in a Lonely Universe (2003). His views about the extent as well as the limits of Neo-Darwinism can be found in his article “Darwin was right. Up to a point.”

James Valentine is Emeritus Professor in the Department of Integrative Biology at the University of California, Berkeley, where he is also affiliated with the Museum of Paleontology and the Center for Integrative Genomics. He is one of the world’s leading experts on the Cambrian Explosion, and is the author of numerous technical articles on the subject, as well as author of the books On the Origin of Phyla and Evolutionary Paleoecology of the Marine Biosphere, co-author of Evolution and Evolving, and editor of Phanerozoic Diversity Patterns: Profiles in Macroevolution.

Paul Chien is a Professor in the Department of Biology at the University of San Francisco. A marine biologist, Dr. Chien received his Ph.D. in Biology from the University of California at Irvine, and he was a postdoctoral fellow at the California Institute of Technology (Caltech). Dr. Chien’s work has been published in over fifty technical journals, and he has spoken internationally, and on numerous occasions, from Brazil to mainland China—where he has also been involved in cooperative research programs. Dr. Chien has done research in the renowned fossil beds of Chengjiang, China.

Jonathan Wells is currently a Senior Research Biologist at the Discovery Institute. He holds two Ph.D.s, one in Molecular and Cell Biology from the University of California at Berkeley, and one in Religious Studies from Yale University. He has worked as a postdoctoral research biologist at the University of California at Berkeley and the supervisor of a medical laboratory in Fairfield, California, and he has taught biology at California State University in Hayward. Dr. Wells has published articles in numerous journals, and he is author of Icons of Evolution: Why much of what we teach about evolution is wrong and The Politically-Incorrect Guide to Darwinism and Intelligent Design, and co-author of The Design of Life.

Richard Sternberg is a Research Scientist at the Biologic Institute and a Research Collaborator at the Smithsonian’s National Museum of Natural History. He is an evolutionary biologist with interests in the relation between genes and morphological homologies, and the nature of genomic “information.” He holds a Ph.D. in Biology (Molecular Evolution) from Florida International University and a Ph.D. in Systems Science (Theoretical Biology) from Binghamton University. From 2001-2007, he served as a staff scientist at the National Center for Biotechnology Information, and from 2001-2007 he was a Research Associate at the Smithsonian’s National Museum of Natural History. Dr. Sternberg’s website can be visited here.

Douglas Axe is Director of Biologic Institute. His research uses both experiments and computer simulations to examine the functional and structural constraints on the evolution of proteins and protein systems. After earning his Ph.D. at the California Institute of Technology, Dr. Axe held postdoctoral and research scientist positions at the University of Cambridge, the Cambridge Medical Research Council Centre, and the Babraham Institute in Cambridge. His work has been reviewed in Nature and featured in a number of books, magazines and newspaper articles, including Life’s Solution by Simon Conway Morris, The Edge of Evolution by Michael Behe, and Signature in the Cell by Stephen Meyer.

Paul Nelson is a philosopher of biology, specializing in evolutionary developmental biology (evo-devo). He earned his Ph.D. from the University of Chicago in 1998, and he is presently an Adjunct Professor in the M.A. Program in Science & Religion at Biola University. He has published articles in such journals as Biology & Philosophy and Zygon and has contributed essays to numerous anthologies.

Stephen Meyer is Director of the Center for Science and Culture at Discovery Institute. Formerly a geophysicist with Atlantic Richfield Company (ARCO), Dr. Meyer earned his Ph.D. in the history and philosophy of science at Cambridge University as a Rotary International Scholar. From 1990-2002, he was on the faculty of Whitworth College. Dr. Meyer is author of peer-reviewed publications in technical, scientific, philosophical and other books and journals. His latest book is Signature in the Cell: DNA and the Evidence for Intelligent Design. His other books include Darwinism, Design and Public Education and Explore Evolution. Dr. Meyer’s website can be visited here.

Is opposition to evolution based on ignorance of the scientific data?

Consider this article by Jonathan Wells.

First, let’s re-cap the challenge to evolution from the phenomenon of the Cambrian explosion.

The newly released film “Darwin’s Dilemma” argues that the geologically abrupt appearance of the major groups of animals (the “phyla”) in the Cambrian Explosion posed a serious problem for Charles Darwin’s theory of evolution (as he himself knew), and that subsequent fossil discoveries—far from solving the problem—have made it worse.

Basically, all the major body plans we have today appear in the fossil record in a 2-3 million period about 543 million years ago. There are no precursors in the fossil record showing the gradual evolution of these major body plans.

The Cambrian Explosion: 0 to 60 in a few million years
The Cambrian Explosion: 0 to 60 in a few million years

Darwin expected to discover lots and lots of fossils leading up to the Cambrian explosion period that would show how all these phyla came into existence slowly over time. Unfortunately for the naturalistic evolutionists, the discoveries we’ve been making haven’t shown any hint of precursor fossils leading up the Cambrian explosion.

Since 1859, however, many Precambrian fossils have been found, including microfossils of single-celled bacteria in rocks more than three billion years old. In addition, multicellular Precambrian fossils have been found in the Ediacara Hills of Australia, though there is continuing debate over whether any—or how many—of the Ediacaran fossils were animals, or what relationship—if any—they had to the Cambrian phyla. In 1998, Cambridge University paleobiologist Simon Conway Morris (who is featured in the film “Darwin’s Dilemma”) wrote, “Apart from the few Ediacaran survivors… there seems to be a sharp demarcation between the strange world of Ediacaran life and the relatively familiar Cambrian fossils” (Crucible of Creation, 30).

But wait! Maybe we can’t find the precusor fossils required by Darwinism because they are too small or too soft to have survived for so long?

Since 1859, however, many Precambrian fossils have been found, including microfossils of single-celled bacteria in rocks more than three billion years old. In addition, multicellular Precambrian fossils have been found in the Ediacara Hills of Australia… In 1998, Cambridge University paleobiologist Simon Conway Morris… wrote, “Apart from the few Ediacaran survivors… there seems to be a sharp demarcation between the strange world of Ediacaran life and the relatively familiar Cambrian fossils” (Crucible of Creation, 30).

So there is now no shortage of Precambrian fossils. Not only do we have fossils of bacteria, but we also have many fossils of soft-bodied Multicellular organisms. “In the Ediacaran organisms there is no evidence for any skeletal hard parts,” wrote Conway Morris in 1998. “Ediacaran fossils look as if they were effectively soft-bodied” (Crucible of Creation, 28). The same is true of many of the organisms fossilized in the Cambrian explosion.

But wait! Scientists have discovered lots of exceptionally preserved microbes just before the Cambrian explosion. Don’t microbes count as precursors to the Cambrian explosion phyla?

Richard Callow and Martin Brasier reported in the January 2009 issue of the Journal of the Geological Society, London “a variety of exceptionally preserved microbes” from late Precambrian rocks in England that address “the paradox known as ‘“Darwin’s dilemma’.”

[…]Callow and Brasier didn’t solve Darwin’s dilemma. Instead, they put one more nail in the coffin of Darwin’s attempt to salvage his theory from it. The truth is that “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.

I am willing to believe in evolution. But in order to get me to believe it, I insist on seeing a fossil record that shows the gradual emergence of phyla, one or two at a time, over hundreds of millions of years. That is what Darwinism predicts. We now have a solid record of what came before the Cambrian explosion. So where are the precursors? Where is the record of gradual emergence? Where is my evidence?

New Illustra Media DVD on the Cambrian Explosion available to pre-order

ARN reports on “Darwin’s Dilemma”, the final DVD in the magnificent intelligent design trilogy.

Excerpt:

The final film in Illustra Media’s long-planned Intelligent Design trilogy, Darwin’s Dilemma, is scheduled for release September 15, 2009 and is currently available for pre-order at ARN at a special introductory price.

This documentary will examine what many consider to be the most powerful refutation of Darwinian evolution-the Cambrian fossil evidence. Charles Darwin realized that the fossil evidence did not support his theory of gradual, step-by-step evolutionary development. He hoped that future generations of scientists would make the discoveries necessary to validate his ideas. Today, after more than 150 years of exploration fossil evidence of slow, incremental biological change has yet to be excavated. Instead, we find a picture of the rapid appearance of fully developed, complex organisms during the outset of the Cambrian geological era. Organisms that embody almost all of the major animal body plans that exist today. This remarkable explosion of life is best explained by the existence of a transcendent intelligence.

Filmed on four continents, this fascinating documentary examines some of the most important fossil discoveries ever made… and, with them, a mystery deeper than Darwin ever imagined. The Cambrian explosion was actually an explosion of biological information: assembly instructions in DNA and embryonic blueprints that directed the development of the first complex animals…information that points unmistakably to foresight, purpose and intelligent design.

Darwin’s Dilemma is a high-quality documentary that includes interviews with world-class paleontologists Simon Conway Morris and James Valentine, as well as leading intelligent design theorists and scientists Paul Nelson, Jonathan Wells, Stephen C. Meyer, Paul Chien, Doug Axe, and Richard Sternberg.

I would click through to ARN’s description if you’re interested, they have a feature list! They also link to the trailer, which you can view online.

Paul Chien and Simon Conway Morris are the top two paleontologists on Cambrian era fossils in the world, in my opinion. (One is an expert on the Burgess Shale in Canada, the other on the Chengjiang Valley in China – the two best locations in the world for Cambrian era fossils). James Valentine is also an expert on the Cambrian era fossils. This will be a HOOT!

I have to tell you a joke. I just bought an Expelled DVD for one of the guys in my office. But a different guy in my office watched it all by himself on the weekend, the same weekend I went to his church, which he has always been trying to get me to do. Well I offered to take the second guy out to lunch so we could talk about it, but he wants me to rake his lawn for him! He has a HUGE lawn in the country!
