Here is a summary of recent podcast of Unbelievable between intelligent design proponent Stephen C. Meyer and UC Berkeley evolutionary biologist Charles Marshall. Dr. Marshall had previously reviewed Dr. Meyer’s new book “Darwin’s Doubt” in the prestigious peer-reviewed journal “Science”.
Stephen C Meyer is the world’s leading Intelligent Design proponent. His new book Darwin’s Doubt claims that the Cambrian fossil record, which saw an “explosion” of new life forms in a short space of time, is evidence for ID.
Evolutionary biologist Charles Marshall of the University of California, Berkeley has written a critical review of the book. He debates Meyer on whether Darwinian evolution can explain the diversity of life in the Cambrian rocks.
The brief summary this time is not provided by me, it’s from Evolution News.
This past weekend Britain’s Premier radio network broadcast a debate between Stephen Meyer and UC Berkeley paleontologist Charles Marshall, recorded at the beginning of November. As David Klinghoffer noted yesterday, the subject of the debate was Meyer’s book Darwin’s Doubt. Yes, that’s the same Charles Marshall who reviewed Darwin’s Doubt in Science back in September. See here for our multiple responses.
It was an excellent debate, with both participants offering important insights and good arguments, though in my opinion Meyer unquestionably had the better of it, especially concerning the key scientific question of the origin of the information necessary to build the Cambrian animals. Nevertheless, both parties came to the table ready to engage in serious, thoughtful, and civil discussion about the core issues raised in Darwin’s Doubt, and we commend Marshall not only for participating, but for focusing his critique of the book on the central scientific issues, something other critics have conspicuously failed to do.
The debate was consequently both constructive and civil. Both parties complimented, as well as critiqued, the work of the other. Marshall, for example, described the first third of Darwin’s Doubt — the section that discusses the Cambrian and Precambrian fossil record, Marshall’s own area of principle expertise — as “good scholarship.” He also said it “looks like good science” and that Meyer “writes well,” and that he (Marshall) “really enjoyed reading”Darwin’s Doubt. Meyer, for his, part expressed his admiration for Marshall’s many scientific papers in paleontology and noted that he had been looking forward to the conversation because he and Marshall clearly “shared a passion for the same subject,” despite their different perspectives. Of course, Marshall is not pro-ID and both men expressed spirited disagreements, but they did so in a mostly respectful way that made the debate all the more interesting and engaging to listen to.
I was very impressed with Dr. Marshall’s performance during the debate, although he did try to poison the well a bit against ID at the beginning, and he got nasty at the end. It’s amazing how Dr. Meyer was able to get him to stop it with the politics and get serious, just by sticking to the science. Even when Marshall got insulting at the end, it was still valuable to see how the other side has to abandon rational argument and scientific evidence once they see that they can’t win on the merits. It’s “Inherit the Wind” in reverse.
Evolution News also posted a more complete guide to the debate in this post, and I recommend that you read that post before listening to the debate if you are not familiar with the science.
This is a great debate, and you definitely ought to listen to it. I hope I’ve posted enough here to convince you. If you haven’t yet bought “Signature in the Cell” and “Darwin’s Doubt“, then I urge you to get them, although they are intermediate/advanced level books. The two books are the state of the art in intelligent design research, good enough to be debated with a University of California, Berkeley professor of biology. Dr. Meyer is the real deal, and if you want to be convincing on these important scientific issues, you need to learn the scientific evidence from his books.
So, just to refresh everyone, the Cambrian explosion was an event that occurred about 543 million years ago. In a very short period of time, less than 10 million years, probably 3-5 million, all of the major animal body plans emerged.
Here’s what the Cambrian explosion looks like:
The Darwinian theory says that there should be precursors to all of the new phyla that appear. But we have never been able to find any precursors. We’ve been looking in the fossil record for the slow transition from simple life to complex life that Darwin predicted, but we’ve never been able to find anything that explains the sudden emergence of the body plans in the Cambrian explosion.
There is no known naturalistic explanation for the rapid emergence of these “phyla”. But, naturalists were holding out hope that maybe a sudden rise in the level of oxygen might have “triggered” the required increase in complexity.
Oxygen is crucial for the existence of animals on Earth. But, an increase in oxygen did not apparently lead to the rise of the first animals. New research shows that 1.4 billion years ago there was enough oxygen for animals — and yet over 800 million years went by before the first animals appeared on Earth.
Animals evolved by about 600 million years ago, which was late in Earth’s history. The late evolution of animals, and the fact that oxygen is central for animal respiration, has led to the widely promoted idea that animal evolution corresponded with a late a rise in atmospheric oxygen concentrations.
“But sufficient oxygen in itself does not seem to be enough for animals to rise. This is indicated by our studies,” say postdoc Emma Hammarlund and Professor Don Canfield, Nordic Center for Earth Evolution, University of Southern Denmark.
[…]The new study is published in the journal Proceedings of National Academy of Sciences.
[…]The results differ from other studies and raise several questions, such as: Why then did animals rise so late in Earth’s history?
“The sudden diversification of animals probably was a result of many factors. Maybe the oxygen rise had less to do with the animal revolution than we previously assumed,” says Hammarlund.
Now look here. I don’t see how a rise in oxygen level can create new body plans. Body plans are written in sequences of symbols – in proteins and DNA. I can no more believe that a rise in oxygen levels could create new animal body plans than I could believe that raising the level of oxygen in a computer lab could explain the new code that is being written by the software engineers. Body plans are information, and new body plans require new information. Information comes from software engineers – intelligent agents – not from rising oxygen levels.
In any case, the hypothesis was falsified. It isn’t the first time a naturalistic hypothesis for the Cambrian explosion was shot down (see below) and it won’t be the last.
It’s Wednesday, so that means another scientific discovery has been made to falsify atheism. Put it on the pile with the others, I guess.
The story from Science Daily reads like Darwinist propaganda, but you can get the main idea if you ignore the fawning naturalistic bias.
A team of Virginia Tech researchers have discovered fossils of kinorhynch worms — commonly known as mud dragons — dating back more than 530 million years.
The historic find — made in South China — fills a huge gap in the known fossil record of kinorhynchs, small invertebrate animals that are related to arthropods, featuring exoskeletons and segmented bodies, but not jointed legs.
The first specimen was unearthed in rocks in Nanjiang, China, in 2013 and more fossils were found later that year and in 2014.
Helping lead the international team of scientists and biomedical engineers who unearthed, studied, and imaged the ancient, armored, worm-like creature is Shuhai Xiao, a professor of geobiology in the Department of Geosciences, part of the College of Science at Virginia Tech.
Dubbed Eokinorhynchus rarus — or rare ancient mud dragon, the newly discovered animal dates back from the Cambrian period and contains five pairs of large bilaterally placed spines on its trunk. It is believed to be related to modern kinorhynchs.
The group’s findings were published in Scientific Reports, a Nature family journal.
“Kinos represent an animal group that is related to arthropods — insects, shrimps, spiders, etc. — which are the most diverse group of animals on the planet,” said Xiao, who refers to kinorhynchs as “kinos” for short. “Although arthropod fossils date back to more than 530 million years ago, no kino fossils have ever been reported. This is a huge gap in the fossil record, with more than 540 million years of evolutionary history undocumented. Our discovery is the first report of kino fossils.”
I took a quick peek at Wikipedia to make sure, and yes, they really are their own phylum. So, brand new phylum.
In Figure 2.5 of Darwin’s Doubt, Steve Meyer reports that about 20 of 27 animal phyla with known fossil records appear in the Cambrian period. Prior to this find, phylum Kinorhyncha was not known to have a fossil record. Now we can update Meyer’s tabulation to report that 21 of the 28 phyla with known fossil records apparently first appear — abruptly no less — in the Cambrian explosion of animal body plans.
Despite this non-Darwinian pattern of origin, the papers’ authors speculate that these ancient (and extant) kinorhynchs might shed light on the origin of arthropods, but that’s largely only because they are segmented — as various other living phyla are as well. Given that kinorhynchs entirely lack limbs and also lack arthropod-like eyes, it seems that they aren’t going to help us much towards understanding the unique defining characteristics of arthropods.
The paper also explains that these fossils come from about 535 million years ago in a section of strata bearing the “small shelly fossils,” in the early Cambrian period. As Meyer and I have discussed, some mistakenly cite the “small shelly fossils” (SSFs) as possible evidence of a gradual evolution of the Cambrian animals. But in this case, studies of the SSFs are showing the Cambrian explosion to be more explosive.
Access Research Network is a group that produces recordings of lectures and debates related to intelligent design. I noticed that on their Youtube channel they are releasing some of their older lectures and debates for FREE. So I decided to write a summary of one that I really like on the Cambrian explosion. This lecture features Dr. Stephen C. Meyer and Dr. Marcus Ross.
The lecture is about two hours. There are really nice slides with lots of illustrations to help you understand what the speakers are saying, even if you are not a scientist.
Here is a summary of the lecture from ARN:
The Cambrian explosion is a term often heard in origins debates, but seldom completely understood by the non-specialist. This lecture by Meyer and Ross is one of the best overviews available on the topic and clearly presents in verbal and pictorial summary the latest fossil data (including the recent finds from Chengjiang China). This lecture is based on a paper recently published by Meyer, Ross, Nelson and Chien “The Cambrian Explosion: Biology’s Big Bang” in Darwinism, Design and Public Education(2003, Michigan State University Press). This 80-page article includes 127 references and the book includes two additional appendices with 63 references documenting the current state of knowledge on the Cambrian explosion data.
The term Cambrian explosion describes the geologically sudden appearance of animals in the fossil record during the Cambrian period of geologic time. During this event, at least nineteen, and perhaps as many as thirty-five (of forty total) phyla made their first appearance on earth. Phyla constitute the highest biological categories in the animal kingdom, with each phylum exhibiting a unique architecture, blueprint, or structural body plan. The word explosion is used to communicate that fact that these life forms appear in an exceedingly narrow window of geologic time (no more than 5 million years). If the standard earth’s history is represented as a 100 yard football field, the Cambrian explosion would represent a four inch section of that field.
For a majority of earth’s life forms to appear so abruptly is completely contrary to the predictions of Neo-Darwinian and Punctuated Equilibrium evolutionary theory, including:
the gradual emergence of biological complexity and the existence of numerous transitional forms leading to new phylum-level body plans;
small-scale morphological diversity preceding the emergence of large-scale morphological disparity; and
a steady increase in the morphological distance between organic forms over time and, consequently, an overall steady increase in the number of phyla over time (taking into account factors such as extinction).
After reviewing how the evidence is completely contrary to evolutionary predictions, Meyer and Ross address three common objections: 1) the artifact hypothesis: Is the Cambrian explosion real?; 2) The Vendian Radiation (a late pre-Cambrian multicellular organism); and 3) the deep divergence hypothesis.
Finally Meyer and Ross argue why design is a better scientific explanation for the Cambrian explosion. They argue that this is not an argument from ignorance, but rather the best explanation of the evidence from our knowledge base of the world. We find in the fossil record distinctive features or hallmarks of designed systems, including:
a quantum or discontinuous increase in specified complexity or information
a top-down pattern of scale diversity
the persistence of structural (or “morphological”) disparities between separate organizational systems; and
the discrete or novel organizational body plans
When we encounter objects that manifest any of these several features and we know how they arose, we invariably find that a purposeful agent or intelligent designer played a causal role in their origin.
Recorded April 24, 2004. Approximately 2 hours including audience Q&A.
You can get a DVD of the lecture and other great lectures from Access Research Network. I recommend their origin of life lectures – I have watched the ones with Dean Kenyon and Charles Thaxton probably a dozen times each. Speaking as an engineer, you never get tired of seeing engineering principles applied to questions like the origin of life.
When people ask me whether the progress of science is more compatible with theism or atheism, I offer the following four basic pieces of scientific evidence that are more compatible with theism than atheism.
Here are the four pieces of evidence best explained by a Creator/Designer:
the kalam argument from the origin of the universe
the cosmic fine-tuning (habitability) argument
the biological information in the first replicator (origin of life)
the sudden origin of all of the different body plans in the fossil record (Cambrian explosion)
And I point to specific examples of recent discoveries that confirm those four arguments. Here are just a few of them:

The impossibility of a bouncing universe
ALAN H. GUTH* & MARC SHER†
*Center for Theoretical Physics, Laboratory for Nuclear Science and Department of Physics, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA
†Department of Physics, University of California, Irvine, California 92717, USA
Petrosian1 has recently discussed the possibility that the restoration of symmetry at grand unification in a closed contracting Robertson–Walker universe could slow down and halt the contraction, causing the universe to bounce. He then went on to discuss the possibility that our universe has undergone a series of such bounces. We disagree with this analysis. One of us (M.S.) has already shown2 that if a contracting universe is dominated by radiation, then a bounce is impossible. We will show here two further results: (1) entropy considerations imply that the quantity S (defined in ref. 1 and below), which must decrease by ~1075 to allow the present Universe to bounce, can in fact decrease by no more than a factor of ~2; (2) if the true vacuum state has zero energy density, then a universe which is contracting in its low temperature phase can never complete a phase transition soon enough to cause a bounce.
The universe is not only expanding, but that expansion appears to be speeding up. And as if that discovery alone weren’t strange enough, it implies that most of the energy in the cosmos is contained in empty space — a concept that Albert Einstein considered but discarded as his “biggest blunder.” The new findings have been recognized as 1998’s top scientific breakthrough by Science magazine.
[…]The flood of findings about the universe’s expansion rate is the result of about 10 years of study, said Saul Perlmutter, team leader of the Supernova Cosmology Project at Lawrence Berkeley National Laboratory.
Perlmutter and others found such a yardstick in a particular kind of exploding star known as a Type 1A supernova. Over the course of several years, the astronomers developed a model to predict how bright such a supernova would appear at any given distance. Astronomers recorded dozens of Type 1A supernovae and anxiously matched them up with redshifts to find out how much the universe’s expansion was slowing down.
To their surprise, the redshift readings indicated that the expansion rate for distant supernovae was lower than the expansion rate for closer supernovae, Perlmutter said. On the largest scale imaginable, the universe’s galaxies appear to be flying away from each other faster and faster as time goes on.
“What we have found is that there is a ‘dark force’ that permeates the universe and that has overcome the force of gravity,” said Nicholas Suntzeff of the Cerro Tololo Inter-American Observatory, who is the co-founder of another group called the High-z Supernova Search Team. “This result is so strange and unexpected that it perhaps is only believable because two independent international groups have found the same effect in their data.”
There has only been one creation of the universe, and the universe will never reverse its expansion, so that it could oscillate eternally. That view is popular, perhaps in part because many people watched videos of Carl Sagan speculating about it in public school classrooms, but all it was was idle naturalistic speculation, (Sagan was a naturalist, and held out hope that science would vindicate naturalism), and has been contradicted by good experimental science. You should be familiar with the 3 evidences for the Big Bang (redshift, light element abundances (helium/hydrogen) and the cosmic microwave background radiation. There are others, (radioactive element abundances, second law of thermodynamics, stellar lifecycle), but those are the big three. Point out how the experimental evidence for the Big Bang has piled up, making the problem even worse for the eternal-universe naturalists.
2) The multiverse has not been tested experimentally, it’s pure speculation.
Multiverse thinking or the belief in the existence of parallel universes is more philosophy or science fiction than science. ”Cosmology must seem odd to scientists in other fields”.
George Ellis, a well-known mathematician and cosmologist, who for instance has written a book with Stephen Hawking, is sceptical of the idea that our universe is just another universe among many others.
A few weeks ago, Ellis, professor emeritus of applied mathematics at the University of Cape Town, reviewed Brian Greene’s book The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos (Knopf/Allen Lane, 2011) in the journal Nature. He is not at all convinced that the multiverse hypothesis is credible: ”Greene is not presenting aspects of a known reality; he is telling of unproven theoretical possibilities.”
According to professor Ellis, there is no evidence of multiverses, they cannot be tested and they are not science.
Ellis is not the only multiverse sceptic in this universe. A few months ago, science writer John Horgan wrote a column in Scientific American, expressing his doubt in multiverses.
When you get into a debate, you must never ever let the other side get away with asserting something they have no evidence for. Call them on it – point out that they have no evidence, and then hammer them with evidence for your point. Pile up cases of fine-tuning on top of each other and continuously point out that they have no experimental evidence for their speculations. Point out that more evidence we get, the more cases of fine-tuning we find, and the tougher the problem gets for naturalists. There is no evidence for a multiverse, but there is evidence for fine-tuning. TONS OF IT.
3) Naturalistic theories for the origin of life have two problems: can’t make the amino acids in an oxydized atmosphere and can’t make protein and DNA sequences by chance in the time available.
Estimating the prevalence of protein sequences adopting functional enzyme folds.
The Babraham Institute, Structural Biology Unit, Babraham Research Campus, Cambridge CB2 4AT, UK. email@example.com
Proteins employ a wide variety of folds to perform their biological functions. How are these folds first acquired? An important step toward answering this is to obtain an estimate of the overall prevalence of sequences adopting functional folds.
[…]Starting with a weakly functional sequence carrying this signature, clusters of ten side-chains within the fold are replaced randomly, within the boundaries of the signature, and tested for function. The prevalence of low-level function in four such experiments indicates that roughly one in 10(64) signature-consistent sequences forms a working domain. Combined with the estimated prevalence of plausible hydropathic patterns (for any fold) and of relevant folds for particular functions, this implies the overall prevalence of sequences performing a specific function by any domain-sized fold may be as low as 1 in 10(77), adding to the body of evidence that functional folds require highly extraordinary sequences.
So atheists are in double jeopardy here. They don’t have a way to build the Scrabble letters needed for life, and they don’t have a way to form the Scrabble letters into meaningful words and sentences. Point out that the more research we do, the tougher the problem gets to solve for naturalists, and the more it looks like an effect of intelligence. Write out the calculations for them.
4) The best candidate to explain the sudden origin of the Cambrian era fossils was the Ediacaran fauna, but those are now recognized as not being precursors to the Cambrian fossils.
Evidence of the single-celled ancestors of animals, dating from the interval in Earth’s history just before multicellular animals appeared, has been discovered in 570 million-year-old rocks from South China by researchers from the University of Bristol, the Swedish Museum of Natural History, the Paul Scherrer Institut and the Chinese Academy of Geological Sciences.
[…]This X-ray microscopy revealed that the fossils had features that multicellular embryos do not, and this led the researchers to the conclusion that the fossils were neither animals nor embryos but rather the reproductive spore bodies of single-celled ancestors of animals.
Professor Philip Donoghue said: “We were very surprised by our results — we’ve been convinced for so long that these fossils represented the embryos of the earliest animals — much of what has been written about the fossils for the last ten years is flat wrong. Our colleagues are not going to like the result.”
Professor Stefan Bengtson said: “These fossils force us to rethink our ideas of how animals learned to make large bodies out of cells.”
The trend is that there is no evolutionary explanation for the body plans that emerged in the Cambrian era. If you want to make the claim that “evolution did it”, then you have to produce the data today. Not speculations about the future. The data we have today says no to naturalism. The only way to affirm naturalistic explanations for the evidence we have is by faith. But rational people know that we need to minimize our leaps of faith, and go with the simplest and most reasonable explanation – an intelligence is the best explanation responsible for rapid generation of biological information.
I do think it’s important for Christians to focus more on scientific apologetics and to focus their academic careers in scientific fields. So often I look at Christian blogs, and I see way too much G. K. Chesterton, Francis Chan and other untestable, ineffective jibber-jabber. We need to bring the hard science, and stop making excuses about not being able to understand it because it’s too hard. It’s not too hard. Everyone can understand Lee Strobel’s “The Case for a Creator“. That’s more than enough for the average Christian on science apologetics. We all have to do our best to learn what works. You don’t want to be anti-science and pro-speculation like atheists are. I recommend reading Uncommon Descent and Evolution News every day for a start.
