What is intelligent design? Dr. Stephen C. Meyer explains the theory

A MUST-SEE lecture based on Dr. Stephen C. Meyer’s book “Signature in the Cell“. (H/T Chris S.)

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 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.

UPDATE: You can see Dr. Stephen C. Meyer debate Dr. Peter Ward as well.

Is intelligent design creationism? Dr. Stephen C. Meyer explains

Dr. Meyer explains the truth in the UK Telegraph.

Excerpt:

In 2004, the distinguished philosopher Antony Flew of the University of Reading made worldwide news when he repudiated a lifelong commitment to atheism and affirmed the reality of some kind of a creator. Flew cited evidence of intelligent design in DNA and the arguments of “American [intelligent] design theorists” as important reasons for this shift.

[…]Contrary to media reports, ID is not a religious-based idea, but an evidence-based scientific theory about life’s origins. According to Darwinian biologists such as Oxford University’s Richard Dawkins, living systems “give the appearance of having been designed for a purpose”.

But, for modern Darwinists, that appearance of design is illusory, because the purely undirected process of natural selection acting on random mutations is entirely sufficient to produce the intricate designed-like structures found in living organisms.

By contrast, ID holds that there are tell-tale features of living systems and the universe that are best explained by a designing intelligence. The theory does not challenge the idea of evolution defined as change over time, or even common ancestry, but it disputes Darwin’s idea that the cause of biological change is wholly blind and undirected.

[…]Consider an even more fundamental argument for design. In 1953, when Watson and Crick elucidated the structure of the DNA molecule, they made a startling discovery. Strings of precisely sequenced chemicals called nucleotides in DNA store and transmit the assembly instructions – the information – in a four-character digital code for building the protein molecules the cell needs to survive. Crick then developed his “sequence hypothesis”, in which the chemical bases in DNA function like letters in a written language or symbols in a computer code. As Dawkins has noted, “the machine code of the genes is uncannily computer-like”.

The informational features of the cell at least appear designed. Yet, to date, no theory of undirected chemical evolution has explained the origin of the digital information needed to build the first living cell. Why? There is simply too much information in the cell to be explained by chance alone.

The information in DNA (and RNA) has also been shown to defy explanation by forces of chemical necessity. Saying otherwise would be like saying a headline arose as the result of chemical attraction between ink and paper. Clearly, something else is at work.

DNA functions like a software program. We know from experience that software comes from programmers. We know that information – whether, say, in hieroglyphics or radio signals – always arises from an intelligent source. As the pioneering information theorist Henry Quastler observed: “Information habitually arises from conscious activity.” So the discovery of digital information in DNA provides strong grounds for inferring that intelligence played a causal role in its origin.

Thus, ID is not based on religion, but on scientific discoveries and our experience of cause and effect, the basis of all scientific reasoning about the past. Unlike creationism, ID is an inference from biological data.

It might be a good idea now to echo Meyer’s claim with something from the secular magazine Scientific American.

Excerpt:

As recently as the middle of the 20th century, many scientists thought that the first organisms were made of self-replicating proteins. After Francis Crick and James Watson showed that DNA is the basis for genetic transmission in the 1950s, many researchers began to favor nucleic acids over proteins as the ur-molecules. But there was a major hitch in this scenario. DNA can make neither proteins nor copies of itself without the help of catalytic proteins called enzymes. This fact turned the origin of life into a classic chicken-or-egg puzzle: Which came first, proteins or DNA?

RNA, DNA’s helpmate, remains the most popular answer to this conundrum, just as it was when I wrote “In the Beginning…” Certain forms of RNA can act as their own enzymes, snipping themselves in two and splicing themselves back together again. If RNA could act as an enzyme, then it might be able to replicate itself without help from proteins. RNA could serve as gene and catalyst, egg and chicken.

But the “RNA-world” hypothesis remains problematic. RNA and its components are difficult to synthesize under the best of circumstances, in a laboratory, let alone under plausible prebiotic conditions. Once RNA is synthesized, it can make new copies of itself only with a great deal of chemical coaxing from the scientist. Overbye notes that “even if RNA did appear naturally, the odds that it would happen in the right sequence to drive Darwinian evolution seem small.”

The RNA world is so dissatisfying that some frustrated scientists are resorting to much more far out—literally—speculation. The most startling revelation in Overbye’s article is that scientists have resuscitated a proposal once floated by Crick. Dissatisfied with conventional theories of life’s beginning, Crick conjectured that aliens came to Earth in a spaceship and planted the seeds of life here billions of years ago. This notion is called directed panspermia. In less dramatic versions of panspermia, microbes arrived on our planet via asteroids, comets or meteorites, or drifted down like confetti.

Naturalists who resort to aliens are still implicating intelligent causes to explain life, ironically enough.

Please share and re-tweet this post, because not understanding intelligent design is a mistake that virtually everyone in the mainstream media makes when discussing this topic. I would bet $100 that there is not a single journalist in the mainstream media who can define intelligent design by citing a peer-reviewed article or academic textbook, and then give an example of where proponents of ID think that intelligent design is evident in nature.

James Shapiro: an honest naturalist admired by ID supporters

As a pro-ID person, I am naturally suspicious of naturalistic scientists. They always say that material forces and chance can explain every single thing in nature, and there are no effects in nature that are best explained by an intelligence. Well, some in nature are best explained by unintelligent causes alone. But I think there are some effects in nature that are more like meaningful sentences or meaningful computer code – and that those are best explained as a result of an intelligence.

One effect in nature where that is clearly analogous to language/code is the biological information in proteins and in DNA. ID people keep telling naturalists that functional information in the first living cell cannot be generated by blind forces in the time available in Earth’s history. But naturalists always seem to diminish the problem and say that blind forces can create information. Well, most naturalists do.

Here’s one who doesn’t, though: James Shapiro. Dr. Shapiro is a microbiologist and a professor in the Department of Biochemistry and Molecular Biology at the University of Chicago. His undergraduate is from Harvard University.

He is very frank about how much naturalistic mechanisms can explain when it comes to the origin of life.

Excerpt: (links removed)

Around here we have a lot of respect for microbiologist James Shapiro, who had the guts and integrity to come over to ENV recently and spar over evolution with William Dembski, Doug Axe and Ann Gauger. Besides having a new book out that details his own dissatisfactions with conventional Darwinian evolutionary theory and that champions a provocative alternative view, Shapiro also blogs at the Huffington Post.

He continues to win our admiration, while evoking some poignancy as well.

In one post that got a fair amount of attention he had some sensible things to say to fellow evolutionists. Rather than hide behind “absolutist statements like ‘all the facts are on my side,'” as his University of Chicago colleague Jerry Coyne does, Shapiro advocates “active engagement” with Darwin critics. Enter into the controversy over evolution, he says, rather than pretend it doesn’t exist.

Perhaps even teach about it? Shapiro doesn’t go that far, but the permissibility of admitting the truth even to young people would seem to follow from his premise:

We need to demonstrate that evolution science is alive and well, as well as show how it is making remarkable progress through the application of molecular technologies — even though it does not have all the answers.

To the thoughtful scientist whose job is to uncover natural processes, this is surely a better way of advocating the scientific method than dogmatically asserting that we found all the scientific principles we need in centuries past.

Evolution supporters, he counsels, should admit they don’t have all the answers, including on a key question like the origin of life. In a remarkably candid statement, he writes:

In order to be truthful, we must acknowledge that certain questions, like the origins of the first living cells, currently have no credible scientific answer. However, given the historical record of science and technology in achieving the “impossible” (e.g., space flight, telecommunications, electronic computation and robotics), there is no reason to believe that unsolved problems will remain without naturalistic explanations indefinitely.

I don’t mind a naturalist who is honest about what we do and do not know.

More:

Surely there’s room to question Shapiro on why our ability to fly to the moon gives grounds for certainty that a purely “naturalistic” explanation of life’s origin will be forthcoming. Space flight is an accomplishment enacted in a material world but, more to the point, it’s a triumph of engineering — aka, intelligent design. It could not be accomplished at all without the direction of purposeful designers.

But note the implicit agreement with Stephen Meyer (Signature in the Cell: DNA and the Evidence for Intelligent Design): materialist explanations for “the origins of the first living cells” have, to date, indeed all miserably failed. In his book, Meyer shows how the evidence points persuasively to the action of some source of intelligent agency. Under the circumstances, if Shapiro is right, that would make intelligent design by default the lone viable theory of life’s origin.

Apart from gesturing to the advance of technology as a reason for keeping faith in naturalism, it would be interesting to know how Shapiro responds to Meyer’s case.

James Shapiro has debated with pro-ID people before. I have a set of audio cassettes from WAY WAY BACK which contains a debate between Robert Shapiro and Walter Bradley, whose lectures on the evidence for design in nature I have featured before. Although some naturalists like Richard Dawkins run away from debates, some, like Shapiro do not. And that’s good for science.

If you want to read a great book on what intelligent design is really about, you really need to read Signature in the Cell. This is the best on the argument for intelligent design in nature from the evidence of proteins and DNA. We are still waiting for a really great pro-ID book on the Cambrian explosion, the sudden origin of all major body plans 540 million years ago – but maybe Dr. Meyer is already working on that now, since he published a peer-reviewed paper on it in a science journal, a while back.
