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.

Details:

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)

Meyer:

  • 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

Fox:

  • 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

Meyer:

  • 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

Fox:

  • 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?

Meyer:

  • 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
Fox:
  • Well, you are just saying that because something is complex that God did it
Meyer:
  • 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
Fox:
  • 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
Meyer:
  • we can’t keep invoking mutation and selection when those processes are not operating prior to the origin of the first living cell
Fox:
  • well maybe some bare-bones self-replication molecule was a precursor to the first living cell
Meyer:
  • 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?
Fox:
  • 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

Meyer:

  • 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
Fox:
  • 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!!!!
Meyer:
  • 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
Fox:
  • So you are saying that we don’t understand and therefore an intelligence is necessary?

Meyer:

  • 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
Fox:
  • well nature is a seamless chain of material causes and effects
Meyer:
  • 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
Fox:
  • you’re trying to impose on science something to do with meaning and purpose
Meyer:
  • 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
Fox:
  • but I am a materialist, I need a materialist explanation
Meyer:
  • 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”

Fox:

  • well DNA is just a molecular polymer, any reference to information is just by analogy
Meyer:
  • 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
Fox:
  • 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
Meyer:
  • you can measure how precise the functional specificity is in DNA and proteins

Moderator: is Shannon information the same as functional information

Meyer:

  • 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
Fox:
  • 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

Meyer:

  • 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
Fox:
  • 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

Meyer:

  • 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? 

Fox:

  • 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

Meyer:

  • 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
Fox:
  • Well, I just have a different philosophy of science that rules out intelligent causation a priori

Meyer:

  • 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.

Is belief in God compatible with belief in evolution?

Sherlock Holmes and John Watson: let's take a look at the facts
Sherlock Holmes and John Watson: let’s take a look at the facts

What should we make of theistic evolutionists telling us that you can believe in God, while still knowing that matter, law and chance fully explain the development of all of biological life?

Consider this quotation from Phillip E. Johnson.

Quote:

The National Academy’s way of dealing with the religious implications of evolution is akin to the two-platoon system in American football. When the leading figures of evolutionary science feel free to say what they really believe, writers such as Edward O. Wilson, Richard Dawkins, Daniel Dennett, Carl Sagan, Steven Pinker, Stephen Jay Gould, Richard Lewontin and others state the “God is dead” thesis aggressively, invoking the authority of science to silence any theistic protest. That is the offensive platoon, and the National Academy never raises any objection to its promoting this worldview.

At other times, however, the scientific elite has to protect the teaching of the “fact of evolution” from objections by religious conservatives who know what the offensive platoon is saying and who argue that the science educators are insinuating a worldview that goes far beyond the data. When the objectors are too numerous or influential to be ignored, the defensive platoon takes the field. That is when we read those spin-doctored reassurances saying that many scientists are religious (in some sense), that science does not claim to have proved that God does not exist (but merely that he does not affect the natural world), and that science and religion are separate realms which should never be mixed (unless it is the materialists who are doing the mixing). Once the defensive platoon has done its job it leaves the field, and the offensive platoon goes right back to telling the public that science has shown that “God” is permanently out of business.

(Phillip E. Johnson: “The Wedge of Truth”, IVP 2000, pp. 88-89).

So what naturalistic scientists believe is that God didn’t do anything to create the diversity of life – that nature does all of its own creating without God. In fact, it doesn’t matter if the best naturalistic explanation is improbable or implausible – naturalists must bitterly cling to materialistic explanations of natural phenomena. Any doubts about the efficacy of naturalistic mechanisms get met by “theistic evolutionists” – scientists who think that science shows that God didn’t do anything in the history of life.

When it comes to discussing origins, you have to be very careful with theistic evolutionists. The one question they want to avoid is whether science, done in the ordinary naturalistic way, can discover evidence of intelligent agency in the history of the development of life. And that’s why you have to ask them that question first. “Is there any scientific evidence that intelligent causes were active during the history of the development of life on this planet?” Their answer to that is the same as atheists, namely: “there is no scientific evidence that intelligent causes are responsible for the effects we see in the history of life on Earth”. Theistic evolutionists and atheists agree on that: as far as pure scientific evidence is concerned, nature can do its own creating without any intelligence writing genetic code or engineering animal body plans.

Now, take a look at this article by Jay Richards. He cites some theistic evolutionists.

Excerpt:

Biologist Ken Miller:

For his part, [Ken] Miller, a biologist, has no qualms about telling us what God would do: “And in Catholicism, he said, God wouldn’t micromanage that way. ‘Surely he can set things up without having to violate his own laws.'”

I am unaware of any tenet of Catholic theology that requires God not to micromanage. It is, however, a tenet of deism.

Got that? What really happened is that God didn’t do anything. How does he know that? From the science? No. Because he assumes naturalism. Oh, it’s true that he says that God is lurking somewhere behind the material processes that created life. But God’s agency is undetectable by the methods of science. And he is hoping that you will accept his subjective pious God-talk as proof that a fundamentally atheistic reality is somehow reconcilable with a robust conception of theism.

More from Richards:

Then we get Stephen Barr offering his private definition of “chance.”

It is possible to believe simultaneously in a world that is shaped by chance and one following a divine plan. “God is in charge and there’s a lot of accident,” said Barr, also a Catholic. “It’s all part of a plan. . . . God may have known where every molecule was going to move.”

What does Barr really believe? He believes that what science shows is that nature created life without any interference by an intelligent agent. Barr then offers believers his subjective pious God-talk to reassure them that evolution is compatible with religion. He has a personal belief – NOT BASED ON SCIENCE – that the material processes that created all of life are “all part of a plan”. He cannot demonstrate that from science – it’s his faith commitment. And more speculations: “God may have known…”. He can’t demonstrate that God did know anything from science. He is just offering a personal opinion about what God “could have” done. The purpose of these subjective opinions is to appease those who ask questions about what natural mechanisms can really create. Can natural causes really account for the development of functional proteins? Never mind that – look at my shiny spiritual-sounding testimony!

That’s theistic evolution. What really happened is that no intelligent causes are needed to explain life. What they say is “God could” and “God might” and “I pray” and “I attend this church” and “I received a Christian award” and “I sing praise hymns in church”. None of these religious opinions and speculations are relevant to the science – they are just opinions, speculations and biographical trivia. Atheists and theistic evolutionists agree on what science shows about the diversity of life – intelligent causes didn’t do anything.

Front-loading?

One of the ways that theistic evolutionists try to affirm design is by insisting that the design is “front-loaded”. The design for all the information and body plans is somehow embedded in matter.

Here is Stephen C. Meyer to assess that:

It’s very important to understand that there is no scientific evidence for design (information) being front-loaded. So although the theistic evolutionists are talking about design, it’s still in the realm of faith – not detectable to scientific investigation. And as Dr. Meyer explained, it doesn’t work to explain design anyway.

I attended a Wheaton College philosophy conference where Dr. Michael Murray read a paper advocating for this front-loaded view of design. I raised my hand to ask him a question, “hey, philosophy guy, did God front-load the information in that paper you’re reading, or did you write it yourself?” But the philosophy moderators must have known that I was an engineer, and would talk sense into him, because they never called on me. However, I did e-mail him later and asked him if he had any evidence for this front-loading theory, and couldn’t God write sequence information in time the same way he had sequenced information in his essay. He replied and said that front-loading was more emotionally satisfying for him. That’s philosophy, I guess. Thank goodness an engineer wrote his e-mail program so that he could at least come clean about his silly view.

The quickest way to disarm a theistic evolutionist is to ask them for a naturalistic explanation of the origin of life. And for a naturalistic explanation of the Cambrian explosion. And so on. Focus on the science – don’t let them turn the conversation to their personal beliefs, or to the Bible, or to religion. No one cares about the psychology of the theistic evolutionist. We only care what science can show.

Stephen C. Meyer lectures on intelligent design and the origin of life

A MUST-SEE lecture based on Dr. Stephen C. Meyer’s book “Signature in the Cell“.

You can get an MP3 of the lecture here. (30 MB)

I highly recommend watching the lecture, and looking at the slides. The quality of the video and the content is first class. There is some Q&A (9 minutes) at the end of the lecture.

Topics:

  • intelligent design is concerned with measuring the information-creating capabilities of natural forces like mutation and selection
  • Darwinists think that random mutations and natural selection can explain the origin and diversification of living systems
  • Darwinian mechanisms are capable of explaining small-scale adaptive changes within types of organisms
  • but there is skepticism, even among naturalists, that Darwinian mechanisms can explain the origin of animal designs
  • even if you concede that Darwinism can account for all of the basic animal body plans, there is still the problem of life’s origin
  • can Darwinian mechanisms explain the origin of the first life? Is there a good naturalistic hypothesis to explain it?
  • there are at least two places in the history of life where new information is needed: origin of life, and Cambrian explosion
  • overview of the structure of DNA and protein synthesis (he has helpful pictures and he uses the snap lock blocks, too)
  • the DNA molecule is composed of a sequence of bases that code for proteins, and the sequence is carefully selected to have biological function
  • meaningful sequences of things like computer code, English sentences, etc. require an adequate cause
  • it is very hard to arrive at a meaningful sequence of a non-trivial length by randomly picking symbols/letters
  • although any random sequence of letters is improbable, the vast majority of sequences are gibberish/non-compiling code
  • similarly, most random sequences of amino acids are lab-proven (Doug Axe’s work) to be non-functional gibberish
  • the research showing this was conducted at Cambridge University and published in the Journal of Molecular Biology
  • so, random mutation cannot explain the origin of the first living cell
  • however, even natural selection coupled with random mutation cannot explain the first living cell
  • there must already be replication in order for mutation and selection to work, so they can’t explain the first replicator
  • but the origin of life is the origin of the first replicator – there is no replication prior to the first replicator
  • the information in the first replicator cannot be explained by law, such as by chemical bonding affinities
  • the amino acids are attached like magnetic letters on a refrigerator
  • the magnetic force sticks the letters ON the fridge, but they don’t determine the specific sequence of the letters
  • if laws did determine the sequence of letters, then the sequences would be repetitive
  • the three materialist explanations – chance alone, chance and law, law alone – are not adequate to explain the effect
  • the best explanation is that an intelligent cause is responsible for the biological explanation in the first replicator
  • we know that intelligent causes can produce functional sequences of information, e.g. – English, Java code
  • the structure and design of DNA matches up nicely with the design patterns used by software engineers (like WK!)

There are some very good tips in this lecture so that you will be able to explain intelligent design to others in simple ways, using everyday household items and children’s toys to symbolize the amino acids, proteins, sugar phosphate backbones, etc.

Proteins are constructed from a sequence of amino acids:

A sequence of amino acids forming a protein
A sequence of amino acids forming a protein

Proteins sticking onto the double helix structure of DNA:

Some proteins sticking onto the sugar phosphate backbone
Some proteins sticking onto the sugar phosphate backbone

I highly, highly recommend this lecture. You will be delighted and you will learn something.

Here is an article that gives a general overview of how intelligent design challenges. If you want to read something more detailed about the material that he is covering in the lecture above related to the origin of life, there is a pretty good article here.

There is a good breakdown of some of the slides with helpful flow charts here on Uncommon Descent.

Positive arguments for Christian theism

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.
