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“. One of my favorite 6 arguments for a Creator and Designer is the origin of the simplest replicating living system. When you look into the cell, what you’ll find is carefully sequenced components that for complex structures, like proteins. In this lecture, you’ll learn all about this “biological information”.

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.


  • 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

Theologian R.C. Sproul asks: “If there’s a God, why are there atheists?”

Brian Auten has a book review posted up at Apologetics 315.

The book is “If There’s A God, Why Are There Atheists?”, by theologian R.C. Sproul. R.C. Sproul is one of my favorite theologians. The book in question has a very, very special place in my heart, because I think that it is one of the major reasons why I was able to resist pernicious ideas like religious pluralism and postmodernism for so long. Once you put on the glasses of Romans 1 and see for the first time what man is really doing with respect to God, you can never see things the same again. I’ll say more about this at the end, but let’s see what Brian wrote first.

The review

So often, you hear atheists complaining about religion is nothing but wish-fulfillment or some sort of crutch for people who are frightened by a variety of things. They think that God is invented to solve several problems. 1) how does the world work?, 2) is there meaning to suffering and evil?, 3) why should I be moral?, and 4) what will happen to me and my loved ones when I die?. On the atheistic view, God is just a crutch that people cling to out of weakness and ignorance. But is this really the case?

Sproul starts the book by investigating three atheists who sought to explain religious belief as a result of psychological factors.

Brian writes:

Before tackling the psychology of atheism, Sproul spends a chapter on the psychology of theism, from the perspective of Freud’s question “If there is no God, why is there religion?” What follows is an overview of various psychological explanations of theistic belief: Feuerbach’s “religion is a dream of the human mind.” Marx’s belief that religion is “due to the devious imagination of particular segment of mankind.” And Nietzche’s idea that “religion endures because weak men need it.” The author properly reiterates: “We must be careful to note that the above arguments can never be used as proof for the nonexistence of God. They can be useful for atheists who hear theists state that the only possible explanation for religion is the existence of God.” That being said, Sproul also reveals what these arguments presume:

Their arguments already presupposed the nonexistence of God. They were not dealing with the question, Is there a God? They were dealing with the question, Since there is no God, why is there religion?16

Sproul points out the weaknesses of each of these approaches and says “there are just as many arguments showing that unbelief has its roots in the psychological needs of man.”

Wow, could that really be true? What are the real reasons why people reject God? Does the Bible have anything to say about what those reasons are?

Brian cites Sproul’s contention:

The New Testament maintains that unbelief is generated not so much by intellectual causes as by moral and psychological ones. The problem is not that there is insufficient evidence to convince rational beings that there is a God, but that rational beings have a natural hostility to the being of God.

[…]Man’s desire is not that the omnipotent, personal Judeo-Christian God exist, but that He not exist.

In Romans 1:18-23, the apostle Paul explains what is really going on:

18The wrath of God is being revealed from heaven against all the godlessness and wickedness of men who suppress the truth by their wickedness,

19since what may be known about God is plain to them, because God has made it plain to them.

20For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse.

21For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened.

22Although they claimed to be wise, they became fools

23and exchanged the glory of the immortal God for images made to look like mortal man and birds and animals and reptiles.

On this blog, I regularly present many, many arguments for theism in general, and Christian theism in particular:

Sproul explains why atheists cannot allow themselves to live according to the evidence that is presented to them:

The cumulative effect of this knowledge that is clearly seen is to leave men ‘without excuse.’ Herein lies the basis of the universal guilt of man. No one can claim ignorance of the knowledge of God. No one can cite insufficient evidence for not believing in God. Though people are not persuaded by the evidence, this does not indicate an insufficiency in the evidence, but rather an insufficiency in man.

[…]The basic stages of man’s reaction to God can be formulated by means of the categories of trauma, repression, and substitution.

[…]If God exists, man cannot be a law unto himself. If God exists, man’s will-to-power is destined to run head-on into the will of God.

And this is the force that is animating atheists today. They don’t want to be accountable to God in a relationship, no matter what the evidence is. They have to deny it, so that they can be free to get the benefits of a universe designed for them, without having to give any recognition or acknowledgement back. If they have to lie to themselves to deny the evidence, they will do it. Anything to insulate themselves from the Creator and Designer who reveals himself in Jesus Christ.

The rest of the book review, and the book, deals with explaining in detail how atheists respond to an all-good, all-powerful, all-knowing Creator/Designer. I encourage you to click through and read the whole book review. You can read the review, and the book, and then investigate for yourself whether atheists really are like that.

Dr. Walter Bradley lectures on scientific evidence the creation and design of the universe

This lecture is special to me, because I bought a VHS tape of it just after I started working full-time, and watched it a million times. A lot of people come to their convictions about God’s existence because of parents or church or intuitions, but for me it’s all about the scientific evidence. This lecture changed my life. I wish more people taught their children about this evidence! This lecture was delivered at the University of California, Santa Barbara.

About the speaker:

Dr. Bradley received his B.S. in Engineering Science and his Ph.D. in Materials Science from the University of Texas in Austin.

Dr. Bradley taught for eight years at the Colorado School of Mines before assuming a position as Professor of Mechanical Engineering at Texas A&M University (TAMU) in 1976.

During his 24 years at Texas A&M, Dr. Bradley served as Head of the Department of Mechanical Engineering at Texas A&M University and as Director of the Polymer Technology Center, and received five College of Engineering Research Awards. He has received over $4,500,000 in research grants and has published over 140 technical articles and book chapters. He has also co-authored “The Mystery Of Life’s Origin: Reassessing Current Theories. He is a Fellow of the American Society for Materials and of the American Scientific Affiliation and serves as a consultant for many Fortune 500 companies.

He currently serves as Distinguished Professor of Engineering at Baylor University.

Summary slide:

This slide summarizes the content of the lecture
This slide summarizes the content of the lecture


  • At the beginning of the 20th century, people believed that the progress of science was pointing away from an intelligent Creator and Designer, and towards naturalism
  • A stream of new discoveries has shifted the support of science towards theism, and away from naturalism
  • Richard Dawkins, an atheist, says that nature only has the appearance of design, but that if you look closer, naturalistic mechanisms can account for the appearance of design
  • When deciding between design and apparent design (“designoid”), it matters whether you think there is an intelligence there to do the designing

Evidence #1: The Big Bang:

  • an eternal “steady state” universe is more compatible with naturalism, but a created universe is more compatible with a Creator
  • In 1929, Hubble used telescopes to observe that the light from distant galaxies was redshifted. The further away galaxies were, the faster they were moving away. Therefore, space is expanding in all directions, suggesting an explosive origin of the universe
  • In 1965, the discovery of the cosmic microwave background radiation matched a prediction of the Big Bang cosmology, and of the creation event
  • In 1992, the COBE space telescope allowed us to test four specific predictions of the Big Bang model, especially the predictions for light element abundances (hydrogen and helium), which matched the predictions of the creation model

Evidence #2: Simple mathematical structure of the physical laws

  • the simple mathematical structure of natural laws allows us to understand these laws, make discoveries, and engineer solutions to problems
  • early scientists saw the mathematical structure of the universe to mean that nature was designed by an intelligent to be understood
  • the fundamental equations of the laws of the universe can be easily written on one side of one sheet of paper
  • Eugene Wigner’s famous paper, “The Unreasonable Effectiveness of Mathematics in the Physical Sciences” makes the point that this simple structure is an unexpected gift that allows is to do science

Evidence #3: fine-tuning of the physical constants and quantities

  • in order for any kind of complex life to survive, we need stars that provide energy within specific ranges for long periods of time
  • in order for any kind of complex life to survive, we need planets with stable orbits that will not suffer from extreme temperature swings as it varies in distance from its star
  • in order for any kind of complex life to survive, we need stable atomic structure
  • in order for any kind of complex life to survive, we need to have chemical diversity and correct relative abundances of each element
  • organic life has minimum requirements: process energy, store information, replicate, and you can’t fulfill those functions if there is only one element, e.g. – hydrogen
  • the energy level from the photons from the sun have to match the energy levels of the different elements in order to drive the chemical bonding needed for life
  • These requirements for life of any imaginable type depend on the values of the constants and quantities. The constants and quantities cannot vary much from what they are, or the universe will lose the characteristics (above) that allow it to support complex life of any imaginable time
  • For example, ratio of strong force to electromagnetic force:
    – if 2% larger, then no stable hydrogen, no long-lived stars, no compounds containing hydrogen, e.g. – water
    – if 5% smaller, no stable stars, heavy hydrogen would be unstable, few elements other than hydrogen

Evidence #4: initial conditions for habitability

  • Universe: expansion rate of the universe must be fast enough to avoid a re-collapse, but slow enough to allow matter to clump together and form stars and planets for complex life to live on
  • Planet: right distance from the star to get the right climate
  • Planet: right mass to retain the right atmosphere

Evidence #5: origin of life and information theory

  • It’s possible to explain every process in an automobile engine using plain old naturalistic mechanisms – no supernatural explanation is necessary to understand the processes
  • But the existence of engine itself: engineering all the parts has to be explained by the work of an intelligence
  • Similarly, we can understand how living systems work, but the existence of the living systems requires an intelligence
  • Even the simplest living system has to perform minimal function: capture energy, store information and replicate
  • Living systems are composed of objects like proteins that are composed of sequences of components complex such that the order of the components gives the overall structure function
  • Developing the components for a simple living cell is very improbable – even given the large number of galaxies, stars and planets in the universe, it is unlikely that complex, embodied life would exist anywhere in the universe

Evidence #6: more initial conditions for habitability

  • Location within the galaxy: you need to be away from the center of the galaxy, because the explosions from dying stars, and excessive radiation will kill life
  • Location within the galaxy: you need to be close enough to the center in order catch the heavy elements you need for life from the explosions of other stars
  • Location within the galaxy: the best location is between two arms of  a spiral galaxy, where you can get the heavy elements you need from dying stars, but without being hit with explosions and harmful radiation
  • Star mass: determines rate at which the sun burns, determines the energy level of photons that are used to drive chemical bonding reactions, determines the length of time the star will be stable
  • Star mass: star mass must be the correct value in order to allow liquid water on the planet’s surface, while still preserving stable orbit

I wish there was more curiosity about science in churches, and young Christians understood how critical science is for grounding the rationality of the Christian worldview. We need to be training up more scientists who think about the big questions, like Dr. Walter Bradley.
