Stephen C. Meyer and Peter Atkins debate intelligent design

This dialog occurred in 2010 on the Unbelievable radio show.

I made a rough transcript, so please see below for that.

The MP3 file is here. (60 minutes)


The documentary film “Expelled” is presented by US Actor Ben Stein and makes the case that scientists who question Darwinian orthodoxy and support Intelligent Design are being “expelled” from academia.

As the UK edition of the DVD is released we ask “Is freedom of thought at stake or is Intelligent Design out of bounds when it comes to biological science?”

Stephen C Meyer is co founder of the Discovery Institute in the USA and a major proponent of Intelligent Design.

Peter Atkins is Professor of Chemistry at Oxford University and an outspoken atheist.

They both feature in “Expelled” and join Justin to debate the pros and cons of Intelligent Design theory.

Mark Haville who is bringing the film to the UK also joins the discussion.

Note: The transcript below is quite snarky and may include paraphrases of Dr. Atkins for the sake of humor.

My rough transcript of the Meyer-Atkins debate

Stephen Meyer:
– started researching on ID while doing his PhD at Cambridge
– the question is whether the information-bearing properties in DNA require a designer
– what cause is adequate to explain the digital code that in the simplest living cell
– alternative explanations like self-organization and RNA-first have failed
– so the best explanation for functional sequences of parts is an intelligent designer
– Darwinists have responded to this argument with insults and suppression of dissent

Peter Atkins:
– intelligent design is creationism
– there is no science at all in it
– information can emerge without an intelligent designer
– structures emerge spontaneously, no agent is needed to generate the structure
– information in DNA is also a structure

Stephen Meyer:
– structure and information are two different things
– many structures emerge spontaneously
– structure may be like the vortex that occurs when water goes down a drain

Peter Atkins:
– the vortex is information

Stephen Meyer:
– structures are different from functionally-specified digital information
– in DNA, there is a 4-digit alphabet that is used to create code sequences
– the thing to be explained is where do the functional sequences come from

Peter Atkins:
– information can grow without an agent
– the second law of thermodynamics
– the universe is falling into disorder
– but there are local abatements of chaos that create information
– evolution can cause the amount of information to grow

Stephen Meyer:
– that’s just an assertion
– I agree that energy flow through a system can produce spontaneous order
– but spontaneous order is not the same thing as information

Peter Atkins:
– spontaneous order is the same as information

Stephen Meyer:
– it’s not order that needs to be explained it’s specified complexity

Peter Atkins:
– what do you mean by specified complexity?

Stephen Meyer:
– the chemical bonds that connect to each letter do not determine the letter
– the chemical bonding sites will accept any letter as easily as any other
– any one of the 4 bases (letters) can attach at any place along the backbone

Peter Atkins:
– the selection of which letter comes next is determined by evolution

Stephen Meyer:
– that is just an assertion
– there is no physical process that sequences the letters to have a function

Peter Atkins:
– do you believe in evolution? YES OR NO!

Mark Haville:
– for him to answer the question you have to define the word
– do you mean macro or micro? biological or stellar? directed or undirected?

Peter Atkins:
– undirected molecules to man evolution by natural processes

Stephen Meyer:
– but even Dawkins doesn’t believe in evolution then
– you’re including the origin of life from non-living matter in evolution
– Dawkins says that there is no known naturalistic explanation for that

Mark Haville:
– you need to define your terms

[They discuss of the movie Expelled and the case of Richard Sternberg]

Stephen Meyer:
– the problem is people don’t want to talk about the science
– they denounce dissent as unscientific
– they will not debate about whther natural causes can explain the information
– I want to talk about the science

Peter Atkins:
– ID people raise interesting questions for naturalists to work on
– but you want to tell us what the answer is (intelligence) before we begin
– you start from the idea that an intelligence was involved

Justin Brierley:
– but you start with the idea that natural mechanisms can explain everything!

Stephen Meyer:
– for Dr. Atkins, only explanations based on material processes are valid

Peter Atkins:
– that is correct

Stephen Meyer:
– but we think that the activities of mind can explain some effects
– e.g. – the best explanation of the Rosetta stone is a mind

Peter Atkins:
– but we naturalists think of minds as material as well

Stephen Meyer:
– that’s a materialist pre-supposition on your part
– we would have to have a debate about mind and body

Mark Haville:
– I think that the materialist position is socially dangerous
– the problem with naturalism is that it is an ideology
– the ideology pushes absurdities, e.g. – the universe came from nothing uncaused
– and naturalists exert power over others to force them to believe nonsense

Stephen Meyer:
– science progresses as the result of scientists disagreeing
– both sides agree to the facts
– the debate is about the interpretation of those facts
– and one side is being ruled out a priori based on the pre-supposition of materialism

Peter Atkins:
– why do you say that an intelligence is involved in DNA but not general relativity

Stephen Meyer:
– it is always logically possible that intelligence can be invlved in any effect
– the main thing is that explanations based on intelligence should not be ruled out

Peter Atkins:
= well you can’t appeal to any non-material process in expaining anything
– those are the rules

– what does intelligent design have to do with religion?

Stephen Meyer:
– creationism is about understanding the istory of life using the Bible
– intelligent design is about using the same method of inquiry as Darwin
– we know that information arises from intelligent causes
– humans create information all the time by using intelligence to sequence parts

– are intelligent design proponents disreputable?

Stephen Meyer:
– what’s disreputable is shutting down debate by setting arbitrary rules

Peter Atkins:
– we are both interested in the same questions

– why won’t you let Stephen publish his papers then?

Peter Atkins:
– because it breaks the pre-suppositions of naturalism and materialism

Stephen Meyer:
– you’re shutting down inquiry by using an arbitrary definition of science

Mark Haville:
– we need to define the word science
– science should be based on what we can observe empirically
– we can observe micro-evolution empirically
– but Darwinism goes beyond what is observable to postulate macro-evolution

Peter Atkins:
– but paleobiology is replete with evidence

Stephen Meyer:
– paleobiology uses a method of inference that I think is valid
– but intelligent design uses the same mode of reasoning which is also valid

Peter Atkins:
= you’re intellectually lazy
– we’re smart, we’re using our brains

– you’re saying that appeals to intelligent causes ends science?
– is ID the view that some things are too complex to be explained with naturalism?

Peter Atkins:
– yes, and to teach children that materialism is false is child abuse

Stephen Meyer:
– let’s drop the insults and the rhetoric and focus on the arguments
– the ID argument is not based on what we don’t know, it’s based on what we DO know
– first, we can ask what undirected natural processes can and cannot do
– second, we can ask what we know about intelligent causes from our own experience
– what we do know seems to me to require an intelligent agent as a cause

Peter Atkins:
– GOD! Do you mean God!? Do you mean God!?

Stephen Meyer:
– I personally mean God, but all that the arguments proves is a generic intelligent cause
– and I am using the same method of investigation that Darwin used to get there
– what we know from our experience is that a mind is needed to create information

Peter Atkins:

Stephen Meyer:
– in my book, I list 10 predictions made by ID, so it’s not a science-stopper
– furthermore, the enterprise of science began with th goal of understanding God
– consider the earliest scientists, people like James Boyler and Johannes Kepler

Peter Atkins:
– that was 300 years ago, we’ve moved on

Mark Haville:
– what about Max Planck then?

Stephen Meyer:
– how about James Clark Maxwell?

Mark Haville:
– we need to focus on the facts

Peter Atkins:
– what do you mean by the facts?

Mark Haville:
– well the fact is that Darwinism has no mechanism to produce new information

Peter Atkins:
– well copying errors introduces beneficial mutations

Stephen Meyer:
– let’s focus on where we get the first information from the simplest organism
– you can’t account for the first organism by appealing to copying errors
– to add functionality to a program, you need new lines codes from an intelligence
– once you have life, you can generate some new information
– but you can’t generate macro-evolution either

Peter Atkins:
– if we give you your explanation for teh origin of life, will you give this up

Stephen Meyer:
– of course! I’m a former theistic evolutionist
– but right now the evidence is not there for it
– we have to decide these questions based on what we see with our own eyes today

Peter Atkins:
– but I pre-suppose materialism as the starting point of all explanations
– you’re just intellectually lazy to abandon my pre-supposition

Stephen Meyer:
– why is it is less intellectually lazy to insist that materialism is true
– we are making plenty of predictions, and isn’t that what science is about?
– consider Junk DNA – you guys said it had no use
– now we know it has a use

Peter Atkins:
– naturalists were open to the idea that junk DNA might have a use before ID

– Dr. Meyer, what about the wall that locks out intelligence as an explanation?

Stephen Meyer:
– if these are interesting questions, then we should allow freedom of inquiry
– that’s how science advances

Peter Atkins:
– for all their science-talk really they are just saying God did it
– people who don’t agree with me are not using their brains, like I do
– to give up on my pre-supposition of materialism is a denial of humanity

Mark Haville:
– there are important issues that are affected by our view of origins
– everyone who hasn’t seen Expelled movie should definitely see it

Stephen C. Meyer and Keith Fox debate intelligent design and evolution

How did life begin?
How did life begin?

From Justin Brierley’s “Unbelievable” podcast.


Stephen Meyer is a leading proponent of Intelligent Design who directs the Centre for Science and Culture at the Discovery Institute in Seattle. His [first] book “Signature in the Cell” claims to show that the DNA code is the product of intelligent mind, not naturalistic processes. Keith Fox is Professor of Biochemistry at Southampton University. He chairs the UK Christians in Science network but disagrees strongly with ID. They debate how life could have originated and whether design is allowed as an explanation in science.

Summary: (stuff in italics is my snarky paraphrase)


  • background and how he got interested in intelligent design
  • his research focus is on the origin of life – the first replicator
  • summarizes the history of origin of life studies
  • authored the book “Signature in the Cell”
  • the DNA enigma: where did the information in DNA come from?
  • naturalistic explanations of the DNA information have failed
  • but intelligent agents are known to be able to produce information
  • the best explanation of the information in DNA is that an intelligent agent authored it
  • Meyer’s book was named by atheist philosopher of science Thomas Nagel as a Times Literary Supplement Book of the Year in 2010
  • why is design so controversial? Many people think that Darwin explained why nature appears design
  • the Darwinian view is that nature can create the appearance of design using mutation and selection
  • however, Darwinian mechanisms cannot explain the origin of the first living cell, it assumes replication, and the origin of life is about where the first replicator comes from


  • Meyer’s argument is not about the evolution of life after the first cell
  • Meyer’s case for design is about the origin of life
  • naturalists do not know a naturalistic explanation for the origin of life
  • there are a number of naturalistic hypotheses for the origin of life, like the RNA-first hypothesis
  • maybe in a few years one of them will turn out to be correct
  • what intelligent design is arguing from a gap in our current naturalistic knowledge to infer that God intervened in nature


  • that’s not what intelligent design is at all
  • the approach ID theorists use is the inference to best explanation
  • you evaluate all explanations, non-intelligent causes and intelligent causes
  • you prefer the best possible explanation
  • we know that minds are capable of producing information just like the information we find in DNA


  • living cells replicate, so they have the ability to introduce mutations as they replicate and then some of those mutations can be selected
  • so maybe the process of replicating that living cells do created the first living cell
  • maybe the first living cell created itself, X brought X into being, self-creation, what’s irrational about that?


  • the issue is the origin of life – where did the first living cell come from?
  • you cannot appeal to the operations that a living cell can perform to explain the origin of the first living cell
  • there was no first living cell operating before the first living cell
  • there was no replication, mutation or selection before the first living cell
  • in fact, in my book I show that there is no known naturalistic mechanism that is able to produce the information needed for the first living cell
  • nothing can create itself, that is self-contradictory
  • Well, you are just saying that because something is complex that God did it
  • Sadly, no. What I actually said needed to be explained was the information, not complexity
  • And we know from software engineering that the process of adding information to code is performed by programmers
  • in the absence of any adequate naturalistic explanation for information, we are justified in taking the explanation that we are familiar with – namely, intelligent agency – based on our uniform, universal experience of what causes information
  • well, maybe we can appeal to the mutation and selection in existing living cells to explain the origin of the first living cell
  • maybe there were living cells before the first living cell, and then these other living cells created the first living cell
  • we can’t keep invoking mutation and selection when those processes are not operating prior to the origin of the first living cell
  • well maybe some bare-bones self-replication molecule was a precursor to the first living cell
  • even to generate very limited replicator would require a large amount of information
  • the argument I am making is – where does the evolution come from?
  • well, maybe we will think of an explanation for information that is naturalistic in 20 years
  • we’ve thought of explanations to things that were NOT information before
  • so maybe we will be able to think of something to explain information based on our ability to explain NOT information before

Moderator: Change topics: the Dover decision


  • the Discovery Institute opposed the policy that causes the trial
  • the wording of the statute was poor
  • the judge was completely wrong in his decision
  • young earth creationists used the phrase “intelligent design” to cover their agenda
  • intelligent design is an inference using the normal methods of science
  • intelligent design is a science stopper because it stops looking for a naturalistic explanation
  • everything in nature must have a naturalistic explanation
  • everything has to be explained using matter and time and chance
  • it just has to be that way!!!!
  • well, what luck would you have explaining an effect like Mt. Rushmore?
  • can you explain that using matter,time and chance?
  • Mt. Rushmore was the product of intelligence, not wind and erosion
  • similarly, there is information in the cell, and we know that intelligence causes information
  • So you are saying that we don’t understand and therefore an intelligence is necessary?


  • no I am saying we DO understand and we are making an inference based on that understanding
  • you are the one who is insisting on a material explanation because you pre-suppose materialism
  • we know that minds have causal powers, and we can infer mind as an explanation from information
  • well nature is a seamless chain of material causes and effects
  • agents can act without violating the laws of nature
  • even humans can act as intelligent agents to create information in books, and they don’t violate the laws of nature
  • intelligent causes are real, and they explain effects in nature
  • you’re trying to impose on science something to do with meaning and purpose
  • no that’s not what we’re doing, we’re inferring from from the fact that we ourselves are known causes of information to the fact that an intelligence cause is the best explanation for information in the cell
  • but I am a materialist, I need a materialist explanation
  • mind IS an answer to the how question
  • we infer to mind in many other scientific disciplines, like cryptography, archaeology, etc.
  • a materialist might accuse an archaeologist of engaging in a “scribe-of-the-gaps” argument, but the best explanation of an artifact with information is a scribe
  • we are inferring that mind is the cause from the nature of the effect: information
Moderator: is it appropriate to call DNA “information”


  • well DNA is just a molecular polymer, any reference to information is just by analogy
  • DNA is a molecular polymer, but it also exhibits the property of specified complexity
  • the arrangement of bases, which function as machine instructions in a software program, for performings task in the cell
  • we have observed that the property of specified complexity always comes from an intelligence
  • well, maybe there are other sequences that would work, so maybe it’s really not uncommon to develop functioning sequences by chance alone, without an intelligence
  • you can measure how precise the functional specificity is in DNA and proteins

Moderator: is Shannon information the same as functional information


  • Shannon information refers to the sequences of digits or symbols that do not necessarily have any function, i.e. – a four character string QSZX has as much Shannon information as WORD. However, only the latter is functional against the pattern of the English language. There are arrangements of DNA bases and amino acids that have the same number of symbols/characters as a functional sequence would have, but they have no biological function – they do not exhibit specified complexity
  • Well, maybe there are lots and lots of sequences of DNA and proteins so that it is fairly easy to get a functional one by chance


  • DNA sequences that are functional are extremely rare, protein sequences are even more rare
  • this is not my opinion, this is what the research shows – functional protein sequences are rare
  • well maybe there are other functional sequences that are occur before the first functional sequence that are precursors to the first functional sequence
  • maybe there are billions of years of replication, mutation and selection before the first replication, mutation and selection


  • you can’t get to the first selectable functional sequence by appealing to precursor selectable functional sequences – there are no selectable functional sequences before the FIRST one
  • you have to get the first selectable functional sequence by chance alone, because there is nothing to mutate or select before the first replicator
  • the chance hypothesis has been rejected because the minimal amount of information for the simplest replicator is too high to get by chance alone, given the resources, including time, that are available

Moderator: Keith are you confident that naturalism will be able to substantiate these naturalism-of-the-gap speculations that you offer in response to Meyer’s actual science that we have today? 


  • well, it is hard to know for sure because it was just a fluke event
  • but there’s nothing irrational or unscientific or miraculous about it – the fluke would have a material explanation
  • there is nothing that we can detect that would implicate God, my speculations about a fluke which I cannot observe or measure or test would all be compatible with an atheistic worldview that omits God as a causal entity


  • where are those material processes that could account for this fluke then?
  • the whole point of this argument is that the information in DNA transcends the material components in the sequence
  • it’s the arrangement of the material parts/letters/characters/symbols/instructions that needs to be explained
  • Well, I just have a different philosophy of science that rules out intelligent causation a priori


  • Yes, that’s the difference between us – you pre-suppose that all explanations of natural phenomena must exclude intelligent causes

There is a bit more where Meyer talks about how parts of the cell are implementations of various design patterns (Gang of Four design patterns) that are used by software architects who design software.

Four ways that the progress of experimental science conflicts with atheism

Apologetics and the progress of science
Apologetics 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.


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

The impossibility of a bouncing universe


*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.

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.


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.

Target acquisition and interception in dragonflies

Apologetics and the progress of science
Apologetics and the progress of science

Here is a fascinating post about some of the capabilities of dragonflies from Evolution News.

Selective attention

First, dragonflies have “selective attention” – the ability to focus on a single prey and ignore other distractions:

Dragonflies are among the best flyers in the insect world. Their twin pairs of paper-thin wings allow them to hover and move in all directions, even in mating. When the time comes to dart after prey at high speed, they rarely miss.

What’s their secret? One is “selective attention” — a trait previously known only in primates, according to new research from the University of Adelaide, Australia. Selective attention is the ability to focus on one object and exclude others. Just as a tennis player must focus on the ball and ignore the cheers of the crowd, a dragonfly must pick out one target from a swarm of insects and avoid being distracted by all the others.

Here’s a snip from the research paper:

Our data make a compelling case that CSTMD1 reflects competitive selection of one target. We emphasize “competitive,” because the attended target is not always the same between trials or even within a trial, as seen in strikingly perfect switches from one to the other…. Competition is further suggested by rare examples where the activity observed under Pair stimulation initially lags both T1and T2 responses… suggesting initial conflict in the underlying neural network before resolution of competition by a “winning” target.

We previously showed that CSTMD1 still responds robustly to a target even when it is embedded within a high-contrast natural scene containing numerous potential distracters. Taken together with recent evidence that the behavioral state of insects strongly modulates responses of neurons involved in visuomotor control, our new data thus suggest a hitherto unexpected sophistication in higher-order control of insect visual processing, akin to selective attention in primates.Perhaps the most remarkable feature of our data is that once the response “locks” onto a target (or following a switch), the second target exerts no influence on the neuron’s response: the distracter is ignored completely.

In order to succeed at the task of catching its prey, the dragonfly has to tune out all other distractions.

Target selection

In addition, dragonflies have the ability to intercept a target in mid-air – similar missile defense systems on AEGIS cruisers and destroyers.

The Evolution News article explains:

Another paper on dragonflies shows that these marvels of the insect world are equipped with navigational equipment that can do vector calculus. In the Proceedings of the National Academy of Sciences, Gonzalez-Bellido and a team at the Howard Hughes Medical Institute discerned “Eight pairs of descending visual neurons in the dragonfly [that] give wing motor centers accurate population vector of prey direction.

Intercepting a moving object requires prediction of its future location. This complex task has been solved by dragonflies, who intercept their prey in midair with a 95% success rate. In this study, we show that a group of 16 neurons, called target-selective descending neurons (TSDNs), code a population vector that reflects the direction of the target with high accuracy and reliability across 360°. The TSDN spatial (receptive field) and temporal (latency) properties matched the area of the retina where the prey is focused and the reaction time, respectively, during predatory flights. The directional tuning curves and morphological traits (3D tracings) for each TSDN type were consistent among animals, but spike rates were not. Our results emphasize that a successful neural circuit for target tracking and interception can be achieved with few neurons and that in dragonflies this information is relayed from the brain to the wing motor centers in population vector form.

What did I make of this? Well, evidence like this always causes me to think aboutthe reality of God, and the disturbing thought that we do not live in an accidental universe where I can do whatever I want and be accountable to no one. It’s easier to believe that – it requires less work and it frees us to be our own boss and make our happiness the first priority. As individuals, it’s very tempting for us to think that we are number one, and to resent our obligations to anyone else. The problem is that the scientific data doesn’t support that worldview. The facts are what they are and it is up to us, now, to try to find out who the designer is and what he wants from us.

John C. Sanford’s genetic entropy hypothesis

Apologetics and the progress of science

JoeCoder sent me a recent peer-reviewed paper by John C. Sanford, so I’ve been trying to find something written by him at a layman’s level so I could understand what he is talking about. (I am just a software engineer, not an expert in genetics). His CV is posted at the Cornell University web page.

I found this 20-minute video of an interview with him, in which he explains his thesis:

The most important part of that video is Sanford’s assertion that natural selection cannot remove deleterious mutations from a population faster than they arrive.

And I also found a review of a book that he wrote that explains his ideas at the layman level.

It says:

Dr. John Sanford is a plant geneticist and inventor who conducted research at Cornell University for more than 25 years. He is best known for significant contributions to the field of transgenic crops, including the invention of the biolistic process (“gene gun”).

[…]Sanford argues that, based upon modern scientific evidence and the calculations of population geneticists (who are almost exclusively evolutionists), mutations are occurring at an alarmingly high rate in our genome and that the vast majority of all mutations are either harmful or “nearly-neutral” (meaning a loss for the organism or having no discernible fitness gain). Importantly, Sanford also establishes the extreme rarity of any type of beneficial mutations in comparison with harmful or “nearly-neutral” mutations. Indeed, “beneficial” mutations are so exceedingly rare as to not contribute in any meaningful way. [NOTE: “Beneficial” mutations do not necessarily result from a gain in information, but instead, these changes predominantly involve a net loss of function to the organism, which is also not helpful to [Darwinism]; see Behe, 2010, pp. 419-445.] Sanford concludes that the frequency and generally harmful or neutral nature of mutations prevents them from being useful to any scheme of random evolution.

[…]In the next section of the book, Sanford examines natural selection and asks whether “nature” can “select” in favor of the exceedingly rare “beneficial” mutations and against the deleterious mutations. The concept of natural selection is generally that the organisms that are best adapted to their environment will survive and reproduce, while the less fit will not. Sanford points out that this may be the case with some organisms, but more commonly, selection involves chance and luck. But could this process select against harmful mutations and allow less harmful or even beneficial mutations to thrive? According to Sanford, there are significant challenges to this notion.

Stanford is a co-author of an academic book on these issues that has Dembski and Behe as co-authors.

Now, I do have to post something more complicated about this, which you can skip – it’s an abstract of a paper he co-authored from that book:

Most deleterious mutations have very slight effects on total fitness, and it has become clear that below a certain fitness effect threshold, such low-impact mutations fail to respond to natural selection. The existence of such a selection threshold suggests that many low-impact deleterious mutations should accumulate continuously, resulting in relentless erosion of genetic information. In this paper, we use numerical simulation to examine this problem of selection threshold.

The objective of this research was to investigate the effect of various biological factors individually and jointly on mutation accumulation in a model human population. For this purpose, we used a recently-developed, biologically-realistic numerical simulation program, Mendel’s Accountant. This program introduces new mutations into the population every generation and tracks each mutation through the processes of recombination, gamete formation, mating, and transmission to the new offspring. This method tracks which individuals survive to reproduce after selection, and records the transmission of each surviving mutation every generation. This allows a detailed mechanistic accounting of each mutation that enters and leaves the population over the course of many generations. We term this type of analysis genetic accounting.

Across all reasonable parameters settings, we observed that high impact mutations were selected away with very high efficiency, while very low impact mutations accumulated just as if there was no selection operating. There was always a large transitional zone, wherein mutations with intermediate fitness effects accumulated continuously, but at a lower rate than would occur in the absence of selection. To characterize the accumulation of mutations of different fitness effect we developed a new statistic, selection threshold (STd), which is an empirically determined value for a given population. A population’s selection threshold is defined as that fitness effect wherein deleterious mutations are accumulating at exactly half the rate expected in the absence of selection. This threshold is mid-way between entirely selectable, and entirely unselectable, mutation effects.

Our investigations reveal that under a very wide range of parameter values, selection thresholds for deleterious mutations are surprisingly high. Our analyses of the selection threshold problem indicate that given even modest levels of noise affecting either the genotype-phenotype relationship or the genotypic fitness-survival-reproduction relationship, accumulation of low-impact mutations continually degrades fitness, and this degradation is far more serious than has been previously acknowledged. Simulations based on recently published values for mutation rate and effect-distribution in humans show a steady decline in fitness that is not even halted by extremely intense selection pressure (12 offspring per female, 10 selectively removed). Indeed, we find that under most realistic circumstances, the large majority of harmful mutations are essentially unaffected by natural selection and continue to accumulate unhindered. This finding has major theoretical implications and raises the question, “What mechanism can preserve the many low-impact nucleotide positions that constitute most of the information within a genome?”

If you think all this is interesting, there is a much longer lecture here, which I have not watched. JoeCoder has watched it and he endorses it.

Now I have been told by JoeCoder that there are many critical responses to his hypothesis, most of which have to do with whether natural selection can overcome the difficulty he is laying out. But since this is not my area of expertise, there is not much I can say to adjudicate here, I won’t be able to respond to these. I hope that I will have time to come back to this and read about it at some point. I do have an e-book of the that collection of papers book I linked to above.
