Stephen C. Meyer and Marcus Ross lecture on the Cambrian explosion

Cambrian Explosion
Cambrian Explosion

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.

If you’d like to see Dr. Meyer defend his views in a debate with someone who reviewed his book about the Cambrian explosion, you can find that in this previous post.

Further study

The Cambrian explosion lecture above is a great intermediate-level lecture and will prepare you to be able to understand Dr. Meyer’s new book “Darwin’s Doubt: The Explosive Origin of Animal Life and the Case for Intelligent Design“. The Michigan State University book that Dr. Meyer mentions is called “Darwin, Design and Public Education“. That book is one of the two good collections on intelligent design published by academic university presses, the other one being from Cambridge University Press, and titled “Debating Design: From Darwin to DNA“. If you think this lecture is above your level of understanding, then be sure and check out the shorter and more up-to-date DVD “Darwin’s Dilemma“.

Yale computer science professor David Gelernter expresses doubts about Darwinism

How did life begin?
How did life begin?

I had to learn about David Gelernter when I was doing my Masters in computer science. We studied his book “Mirror Worlds”. A few weeks ago, I blogged about his impressions of the difficulty in forming a simple protein by chance – something that naturalistic mechanisms would have to do in order to avoid intelligent agency as a cause in nature. He found it very unlikely. But there’s more!

Recently, my friend Terrell sent me a video featuring Peter Robinson (who hosts the splendid Uncommon Knowledge show out of Stanford University), and three interesting people. First, there was Dr. Stephen C. Meyer, who is one of my two favorite thinkers. I’ve blogged on his work about the origin of life and the Cambrian explosion here many times. Then, there was Dr. David Berlinski, a secular Jewish professor of mathematics, who has studied origins issues. And then Dr. David Gelernter, who teaches computer science at Yale University, and is a legend in computer science research.

Here’s the video: (H/T Terrell)

Here is an article by Jennifer Kabbany in The College Fix about the video.

She writes about his recent Claremont Review of Books article, as well as the interview above:

In May, the Claremont Review of Books published a column by Gelernter headlined “Giving Up Darwin.” In it, he explained how his readings and discussions of Darwinian evolution and its competing theories, namely intelligent design, have convinced him Darwin had it wrong.

In particular, he cited Stephen Meyer’s 2013 book Darwin’s Doubt as well as The Deniable Darwin by David Berlinski. The professor expanded on his views in an interview with Stanford University’s Hoover Institution that was published last week.

Gelernter stops short of fully embracing intelligent design, both in his essay and during his interview. He said in his interview he sees intelligence in Earth’s design, and has no quarrel with ID proponents, but notes the world a mess, its suffering far outweighs its goodness.

“My argument is with people who dismiss intelligent design without considering, it seems to me — it’s widely dismissed in my world of academia as some sort of theological put up job — it’s an absolutely serious scientific argument,” Gelernter said during his interview. “In fact it’s the first and most obvious and intuitive one that comes to mind. It’s got to be dealt with intellectually.”

I found this part the most interesting, since we are seeing so much intolerance from the secular left, whenever anyone disagrees with their dogma:

Gelernter said he likes many of his colleagues at Yale, that they are his friends, but when he looks at “their intellectual behavior, what they have published — and much more importantly what they tell their students — Darwinism has indeed passed beyond a scientific argument as far as they are concerned. You take your life in your hands to challenge it intellectually. They will destroy you if you challenge it.”

“Now, I haven’t been destroyed, I am not a biologist, and I don’t claim to be an authority on this topic,” Gelernter added, “but what I have seen in their behavior intellectually and at colleges across the West is nothing approaching free speech on this topic. It’s a bitter, fundamental, angry, outraged rejection [of intelligent design], which comes nowhere near scientific or intellectual discussion. I’ve seen that happen again and again.”

Gelernter acknowledges “I am attacking their religion and I don’t blame them for being all head up, it is a big issue for them.”

Dr. Gelernter cited three arguments in his article: the origin of life, and the Cambrian explosion, and genetic entropy. In the first two problems, there is a problem of huge amounts of biological information coming into being . We know that software engineers can write code like that, but there is no Darwinian mechanism for writing that much code and that short of a time period. The third problem shows that Darwinian mechanisms not only don’t produce functional code – they actually break it down.

I’ve covered both of the arguments before on this blog, but if you really want the details, you should pick up the books that convinced Dr. Gelernter: Dr. Stephen C. Meyer’s “Signature in the Cell” and “Darwin’s Doubt”. Each book tackles one of the arguments. For the third problem, a good book is Dr. Michael Behe’s “Darwin Devolves”. Even if you just read something about each book, then you’ll know about the arguments for intelligent causes being the best explanation for the history of life on this planet.

Video, audio and summary of intelligent design discussion, with Ben Shapiro and Stephen C. Meyer

Stephen C. Meyer and Ben Shapiro discuss evolution and intelligent design

This is a must-see / must-hear conversation. Famous conservative Ben Shapiro discusses evolution and intelligent design with Dr. Stephen C. Meyer, author of “Signature in the Cell” (origin of life) and “Darwin’s Doubt” (fossil record). These are the two best books on intelligent design. Their conversation covers the most important issues in the origins debate.

So to start, here’s the full video:

And here is a link to the audio. You can download the MP3 there.

Someone actually put out an outline on Youtube, with a time-based index, so I’ll just steal that as a base, and add to it:

  • 1:34 What is your scientific background? Science undergraduate degree, professional geologist, later did a PhD in philosophy of science from Cambridge University.
  • 2:39 What is the difference between intelligent design and creationism? Creationism starts from the Bible and posits a shorter history of the universe. ID starts from the data of the natural world and is neutral about the age of the Earth / universe. Meyer accepts the old-Earth.
  • 3:36 How is Intelligent Design a scientific theory? The discovery of DNA reveals that code is central to living systems. Intelligent design uses the method of “inference to the best explanation” in order to argue that the best explanation for the code is an intelligent agent.
  • 6:10 What evidence would have to arise to make Intelligent Design Falsifiable? If a naturalistic mechanism was discovered that could produce biological information using the probabilistic resources of the universe, and the time available, then intelligent design would be falsified.
  • 7:26 Is religion separate from science or intertwined within it? There are three views: science is totally separate from religion, science is in total conflict with religion, science and religion agree on some issues, e.g. – the origin of the universe and Genesis 1:1. There are areas where science and religion overlap.
  • 9:55 Why are the most prominent Darwinians also militant atheists? Evolution is a theory that tries to explain nature using naturalistic mechanisms, so it is compatible with atheism.
  • 10:45 What does the theory of evolution say? The term evolution has multiple meanings, and should be defined before discussions. It can refer to change over time. It can refer to animals changing slightly to adapt to enviromental changes. It can refer to the idea that all animals evolved from simpler life forms, and that there is a tree of life showing how different types of organisms share common ancestors. And it can refer to the idea that purely undirected processes can explain the history of life using purely materialistic forces. It’s that final view that intelligent design challenges.
  • 13:15 Where is the discontinuity in naturalistic processes in the development of life? The first discontinuity is the origin of simple life from non-living components. The second discontinuity is the sudden appearance of different body plans in a very narrow window of time in the Cambrian era.
  • 15:42 Why does information theory suggest that code requires some sort of designer? DNA is a true information-bearing system identical to the software in computers, e.g. – operating system, applications.
  • 19:45 Can information be created by random mutation, and favorable mutations preserved by natural selection? Just as in software code, instructions must be added in order to develop new functionality. Random additions of characters will almost always degrade biological function. The number of possible sequences that do nothing useful is vastly higher than the number of sequences that perform biological functions. Doug Axe did research on this at Cambridge University, and he found that the number of functional sequences of amino acids is 1 in 10 to the 77th power. Given the probabilistic resources (replicating organisms)and the time available, it is extremely unlikely to find sequences that have functional information by chance.
  • 25:05 What about Stephen Jay Gould’s model of punctuated equilibrium – doesn’t it explain the sudden jumps in information? Gould’s mechanism is accurate according to the fossil record, which shows a lot of jumps. But he did not have a naturalistic explanation for sudden jumps in biological function. Darwinian mechanisms work slowly and would (in theory) produce different body plans gradually. But this is not what the fossil record shows.
  • 27:22 What is the mechanism for injecting information in the theory of intelligent design? The information comes in from an intelligence when new major body plans appear, and minor variations within types could be explained by evolution.
  • 29:25 Does the Miller-Urey experiment provide a naturalistic explanation for the building blocks necessary for the origin of life? The MU experiment only produced a few types of amino acids, it doesn’t say anything about how to sequence the amino acids in order to form protein folds that can perform biological functions. The MU experiment also pre-supposes conditions on the early Earth (reducing gases) that do not match what was there (oxidyzing or neutral gases).
  • 32:00 Is the RNA world hypothesis is a good explanation for the origin of life? Evolution requires that replication already be in place, because evolution assumes that mutations appear during the replication. The RNA world hypothesis suggests that sequences contain information, but also catalyze origin of life chemistry. The problem with RNA world is that it starts with self-replicating systems. And those replicating systems require the scientist to inject information into the system to get even the simplest replication started.
  • 34:56 How do scientists respond to the critiques of Darwinism proposed by intelligent design advocates? By and large, they accept them. They think that mutation and selection works once living systems are in place, but they realize it has no explanation for the origin of life or the sudden origin of body plans. (Tells about the  conference of the Royal Society, where problems with Darwinian mechanisms were discussed, and the 2003 MIT Press book by Muller and Newman).
  • 37:16 Why do people hold to Darwinian evolution in the face of these problems? Many scientists presuppose methodological naturalism, which requires that any explanation for the origin of life and the origin of major body plans involve materialist explanations only. No intelligent agents are allowed. The problems occur when assumption of naturalism causes scientists to propose incorrect explanations for what we observe in nature. It’s also not clear how naturalistic mechanisms could produce organisms who are capable of reason and free will.
  • 40:43 Does naturalistic evolution have an answer for conscious minds, reasoning, free will? No, consider the work of atheist scholar Thomas Nagel, who argues in his book “Mind and Cosmos” (Oxford University Press 2012) that the existence of mind is a disproof of the neo-Darwinian explanation for life. Darwinism stops us from accepting the reality of minds.
  • 42:06 So do naturalistic evolutionists have to explain away the mind as an illusion? First, we humans have immediate experience of consciousness, reason and free will. Second, our whole legal system is based on the idea free will, because you can’t hold someone guilty unless they chose to do something they knew was wrong. Third, we have an epidemic of suicide among young people. This is caused by a crisis of meaning. Intelligent design opens up the possibility of their being a mind behind the universe, who we could have a relationships with.
  • 44:53 Why aren’t schools allowed to be honest about the problems with neo-Darwinian evolution? The intellignt design view is to that teachers should be allowed to teach all the vidence for Darwinian evolution, and also discuss some of the problems with the theory. Students learning science should not be told that everything is solved. Students learn science better when they are presented with peer-reviewed evidence for and against a theory, rather than being indoctrinated.
  • 47:37 Is intelligent design theory connected to God? Intelligent design infers from the information content in nature that a mind with capabilities like ours injected information into living systems. Intelligent design is agnostic about the designer, because in principle, embodied or unembodied agents could inject information into living systems. Intelligent design is friendly to theism, because theists will immediately identify the mind as God. Furthermore, the fine-tuning in the initial conditions of the universe is another intelligent design argument. In that case, since the design occurs at the beginning of the universe, the intelligent agent acting prior to the creation of the universe would have to be supernatural, i.e. – God.
  • 50:53 Can naturalists say that the imposition of “function” on a sequence is arbitrary, in the same way that the English language is arbitrary? This won’t work, because biological function is not arbitrary in the same way as language. Biological function is not arbitrary, because sequences can be tested for function objectively by observing whether sequences can perform functions necessary for life, e.g. – replication.
  • 52:43 Doesn’t the multiverse explain away the improbabilities of the fine-tuning, the origin of life, and the development of life? No, because all models of the multiverse require fine-tuning in the mechanism that generates the different universes.
  • 55:42 What about cosmological models that eliminate the beginning of the universe? The standard Big Bang model and the inflationary model both posit a beginning of the universe. There is also the Borde-Guth-Vilenkin theory which proves that any universe that is expanding requires a beginning. The only chance for naturalists is quantum cosmologies, but this doesn’t work because 1) it requires an abstract reality of mathematics to actualize the physical universe, but this presupposes a mind. 2)  The model requires an earlier input of information, which can only have come from a mind.

If you listen to this lecture, or watch the video, and you enjoyed it, then please share. If you have questions, I can try to answer them for you – just leave your question in the comments, or shoot me an e-mail, or message me from the blog’s Facebook page, or direct message me on Twitter. I’ve invested a lot of time in this, and have been studying intelligent design since the late 1990s.

By the way, I listen to the Ben Shapiro podcast, (and the Andrew Klavan podcast), every day. I never miss an episode, and I think if you give them a try, you’ll enjoy them, too.

How brief was the period in which the Cambrian phyla suddenly appeared?

The Cambrian explosion refers to the sudden appearance of new body plans in the fossil record. ID proponents think that the period is between 5-10 million years at the most. Naturalists want to stretch out the period in which the body plans appear to tens of millions of years. The two sides can’t both be right. What’s the truth?

Evolution News has the answer.

Excerpt:

To establish the length of the most explosive period of innovation within the Cambrian explosion itself, Meyer cites the work of MIT geochronologist Samuel Bowring and his colleagues as well the work of another group led by Smithsonian paleontologist Douglas Erwin. The Bowring-led study showed that (in their words) “the main period of exponential diversification” within the Cambrian lasted “only 5-6 million years” (emphasis added). Meyer explains:

An analysis by MIT geochronologist Samuel Bowring has shown that the main pulse of Cambrian morphological innovation occurred in a sedimentary sequence spanning no more than 6 million years. Yet during this time representatives of at least sixteen completely novel phyla and about thirty classes first appeared in the rock record. In a more recent paper using a slightly different dating scheme, Douglas Erwin and colleagues similarly show that thirteen new phyla appear in a roughly 6-million-year window. (p. 73)

[…][T]ake a look first at the following figure that Bowring and his colleagues included in their definitive 1993 article, published in the journal Science. They use radiometric methods to date the different stages of the Cambrian period, including the crucial Tommotian and Atdabanian stages in which the greatest number of new animal phyla and classes arise. Note that the so-called Manykaian stage of the Cambrian period lasts about 10-14 million years. Note also that the main pulse of morphological innovation didn’t begin during this stage but rather during the Tommotian and Atdabanian — a period that they describe as taking between “5 to 10 million years,” and in a more detailed passage as taking about 5-6 million years.

[…]In the figure above, the Tommotian and Atdabanian stages of the Cambrian period together span only about 5 million years, starting at about 530 and ending about 525 million years ago. Bowring’s figure also depicts the total number of classes and orders present at any given time during the Cambrian period. The biggest increases in morphological innovation occur during the Tommotian and Atdabanian stages. Indeed, during this period the number of known orders nearly quadruples. Moreover, Bowring and his colleagues also make clear that this period corresponds to the main pulse of Cambrian morphological innovation as measured by the number of new phyla and classes that first appear. They note that, while a few groups of animals do arise in the earliest Manykaian stage of the Cambrian, the most rapid period of “exponential increase of diversification,” corresponding to the Tommotian and Atdabanian stages, “lasted only 5 to 6 m.y.”

You can see the figure they are reference in the Evolution News article.

Also, check out these clips that explain the Cambrian explosion:

Part 1:

Part 2:

The first clip features James Valentine, a professor of biology at the University of California who just co-authored a new book on the Cambrian explosion and is not a proponent of intelligent design.

The consensus among scientists regarding the period of time in which the new body plans appear is 5-6 million years. Biologically speaking, that’s a blink of an eye. You aren’t going that kind of complexity and innovation in such a short period of time any more than you can expect to win the lottery by buying 5-6 million tickets when the odds of winning are 1 in a googol (10 to the 100th power – 1, followed by 100 zeroes). You don’t have enough lottery tickets to make winning the lottery likely. Similarly, 5-6 million years is not enough time for naturalistic mechanisms to code brand new body plans from scratch. It would be like trying to research and write a Ph.D thesis during a single lunch hour. It’s just not enough time to produce the amount of information that’s required.

Four ways that the progress of experimental science conflicts with atheism

Christianity and the progress of science
Christianity and the progress of science

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:

  1. the kalam argument from the origin of the universe
  2. the cosmic fine-tuning (habitability) argument
  3. the biological information in the first replicator (origin of life)
  4. 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:

  1. An explanation of 3 of the 6 experimental evidences for the Big Bang cosmology (From an article from Caltech)
  2. Examples of cosmic fine-tuning to allow the existence of conscious, embodied life (From the New Scientist)
  3. Evidence that functional protein sequences are beyond the reach of chance, (from Doug Axe’s JMB article)
  4. Evidence showing that Ediacaran fauna are not precursors to the Cambrian fossils, (from the journal Nature)

Atheists will typically reply to the recent scientific discoveries that overturned their speculations like this:

  1. Maybe the Big Bang cosmology will be overturned by the Big Crunch/Bounce so that the universe is eternal and has no cause
  2. Maybe there is a multiverse: an infinite number of unobservable, untestable universes which makes our finely-tuned one more probable
  3. Maybe the origin of life could be the result of chance and natural processes
  4. Maybe we will find a seamless chain of fossils that explain how the Cambrian explosion occurred slowly, over a long period time

Ever heard any of these responses?

Below I list some resources to help you to respond to the four responses of atheists to the experimental data.

1) The Big Crunch/Bounce has been disproved theoretically and experimentally.

Theoretically:

Nature 302, 505 – 506 (07 April 1983); doi:10.1038/302505a0

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.

Experimentally:

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.

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.

[…]These results suggest that outgassing of Earth’s interior later than ~200?Myr into the history of Solar System formation would not have resulted in a reducing atmosphere.

Estimating the prevalence of protein sequences adopting functional enzyme folds.

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.

Science Daily reports on a paper from the peer-reviewed journal Science:

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.

Conclusion

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 A. W. Tozer, 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.
