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

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

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

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.

Stephen C. Meyer and Doug Axe discuss 5 major problems with macro-evolution

Undeniable: How Biology Confirms Our Intuition That Life Is Designed
Undeniable: How Biology Confirms Our Intuition That Life Is Designed

The host of the Cross Examined radio show Dr. Frank Turek talks with Stephen C. Meyer and Doug Axe about a recent conference of Royal Society scientists discussing the problems with the theory of macro-evolution.

The MP3 file is here.

Summary:

  • about the Royal Society conference
  • the main topic was whether naturalistic mechanisms can produce new body plans and new organ types
  • no one disputes micro-evolution: beaks changing size, antibiotic resistance
  • many of the naturalistic scientists admitted the problems with current naturalistic theories, but they don’t want to embrace the need for a designer
  • none of the proposals that were debated solved the real problems with macro-evolution
  • Problem #1: the sudden origin of body plans in the fossil record
  • Problem #2: the origin of information (e.g. – in protein molecule)
  • Problem #3: need for favorable early mutations (for body plans)
  • Problem #4: the problem of epigenetics
  • Problem #5: the universality of the design intuition

Some of these problems have actually gotten worse for naturalistic evolution as our scientific knowledge has grown.

If you want the two best books on intelligent design, get Dr. Meyer’s “Signature in the Cell” and “Darwin’s Doubt”. I should note that Dr. Meyer is not a young Earth creationist, and has defended the Big Bang cosmology as a solid evidence for a Creator of the universe. Being in favor of an old universe and an old Earth is compatible with being opposed to evolution – because of scientific reasons.

Stephen C. Meyer debates intelligent design with two scientists on NPR

Evolution News reported on a 27-minute debate featuring Dr. Stephen C. Meyer – probably the best proponent of intelligent design there is.

Description:

We often say that Darwinists are reluctant to debate advocates of intelligent design, but here are two who deserve a tip of the hat. Keith Pannell is a chemist at the University of Texas at El Paso who hosts a program, Science Studio, on the NPR station there. He invited Stephen Meyer on to talk about the science of ID, pegged to the Dover anniversary.

Clearly Pannell is an ID critic so he gets kudos for being willing to have a civil and informative conversation. Perhaps feeling insecure about facing the author of Darwin’s Doubt by himself, Dr. Pannell invited a biologist colleague, Ricardo Bernal, to serve as “co-host.”

So it was two against one, but no worries. Meyer is, as always, superb, and the discussion sounds like it was an education for the two Texas scientists. Listen and enjoy.

I took a back-up of the MP3 file here.

Summary:

  • How did Dr. Meyer get interested in science?
  • What is intelligent design? (origin of life, fine-tuning)
  • What is creationism? (young Earth, different epistemology)
  • Who does Dr. Meyer think the intelligent designer is?
  • Finding the best explanation from multiple competing hypotheses
  • Critic: aren’t you arguing for a designer from ignorance, then?
  • The importance of naturalists acknowledging what they do and do not know about the origin of life
  • We do have experience with intelligent causation, whenever we sequence symbols to have meaning and purpose, e.g. – writing
  • Critic: information in DNA is not digital information, is it?
  • Information in the cell follows a 4-character alphabet
  • the sequences are composed of many parts / symbols
  • the sequences themselves are specified to have function
  • Critic: the complexity just emerges from change over time
  • the origin of the first life is immune to explanation of change over time, because there is no replication – this is the first replicator
  • Critic: but isn’t it just ignorance about the origin of life?
  • what we do is look at a number of competing hypothesis and what they are capable of, and see whether each cause is capable of generating the effects we observe in nature
  • Critic: where is the experimental verification of your theory?
  • well, in the appendices of Signature of the Cell, we predicted that the non-coding regions of DNA (junk DNA) would be found to have function, and that was later proven out
  • the Darwinists said that non-coding regions of the DNA was junk, but that’s not what has been proven experimentally
  • Critic: where was this prediction written up, who wrote it?
  • intelligent design theorists predicted it: Dembski, Kenyon, Mims, Sternberg
  • Critic: but we used the scientific method to disprove the Darwinian predictions, you don’t like the scientific method
  • intelligent design proponents love science, and the scientific method, and they do work in labs to confirm their hypotheses, (WK:for example, the probability of generating a protein by chance)
  • Critic: what about the Dover court case that you lost?
  • the Discovery Institute objected to actions taken by the Dover school board
  • Critic: what about the molecular machines, how are they related to intelligent design?
  • even in the simplest living organisms, there are tiny machines that are tightly integrated, and cannot be built up in a stepwise fashion
  • Critic: I’ve worked with the ATP-synthase and other molecular machines, but “you can kind of begin to tease how some of these molecular machines have come about” – pieces have multiple functions, and they are co-opted into larger systems
  • the problem with the co-option argument breaks down when you look at the specific details of different machines
  • for example – the type III secretory system cannot be an precursor to the bacterial flagellum, it is younger, not older than the bacterial flagellum
  • Critic: what would it take for your view to be falsified?
  • demonstrable undirected processes that are capable of creating functional information in DNA, or processes that can build up an irreducibly complex molecular machine within the time available with a decent probability
