Stephen C. Meyer and Marcus Ross lecture on the Cambrian explosion

Cambrian Explosion
Cambrian Explosion

Access Research Network is a group that produces recordings  of lectures and debates related to intelligent design. I noticed that on their Youtube channel they are releasing some of their older lectures and debates for FREE. So I decided to write a summary of one that I really like on the Cambrian explosion. This lecture features Dr. Stephen C. Meyer and Dr. Marcus Ross.

The lecture is about two hours. There are really nice slides with lots of illustrations to help you understand what the speakers are saying, even if you are not a scientist.

Here is a summary of the lecture from ARN:

The Cambrian explosion is a term often heard in origins debates, but seldom completely understood by the non-specialist. This lecture by Meyer and Ross is one of the best overviews available on the topic and clearly presents in verbal and pictorial summary the latest fossil data (including the recent finds from Chengjiang China). This lecture is based on a paper recently published by Meyer, Ross, Nelson and Chien “The Cambrian Explosion: Biology’s Big Bang” in Darwinism, Design and Public Education(2003, Michigan State University Press). This 80-page article includes 127 references and the book includes two additional appendices with 63 references documenting the current state of knowledge on the Cambrian explosion data.

The term Cambrian explosion describes the geologically sudden appearance of animals in the fossil record during the Cambrian period of geologic time. During this event, at least nineteen, and perhaps as many as thirty-five (of forty total) phyla made their first appearance on earth. Phyla constitute the highest biological categories in the animal kingdom, with each phylum exhibiting a unique architecture, blueprint, or structural body plan. The word explosion is used to communicate that fact that these life forms appear in an exceedingly narrow window of geologic time (no more than 5 million years). If the standard earth’s history is represented as a 100 yard football field, the Cambrian explosion would represent a four inch section of that field.

For a majority of earth’s life forms to appear so abruptly is completely contrary to the predictions of Neo-Darwinian and Punctuated Equilibrium evolutionary theory, including:

  • the gradual emergence of biological complexity and the existence of numerous transitional forms leading to new phylum-level body plans;
  • small-scale morphological diversity preceding the emergence of large-scale morphological disparity; and
  • a steady increase in the morphological distance between organic forms over time and, consequently, an overall steady increase in the number of phyla over time (taking into account factors such as extinction).

After reviewing how the evidence is completely contrary to evolutionary predictions, Meyer and Ross address three common objections: 1) the artifact hypothesis: Is the Cambrian explosion real?; 2) The Vendian Radiation (a late pre-Cambrian multicellular organism); and 3) the deep divergence hypothesis.

Finally Meyer and Ross argue why design is a better scientific explanation for the Cambrian explosion. They argue that this is not an argument from ignorance, but rather the best explanation of the evidence from our knowledge base of the world. We find in the fossil record distinctive features or hallmarks of designed systems, including:

  • a quantum or discontinuous increase in specified complexity or information
  • a top-down pattern of scale diversity
  • the persistence of structural (or “morphological”) disparities between separate organizational systems; and
  • the discrete or novel organizational body plans

When we encounter objects that manifest any of these several features and we know how they arose, we invariably find that a purposeful agent or intelligent designer played a causal role in their origin.

Recorded April 24, 2004. Approximately 2 hours including audience Q&A.

You can get a DVD of the lecture and other great lectures from Access Research Network. I recommend their origin of life lectures – I have watched the ones with Dean Kenyon and Charles Thaxton probably a dozen times each. Speaking as an engineer, you never get tired of seeing engineering principles applied to questions like the origin of life.

If you’d like to see Dr. Meyer defend his views in a debate with someone who reviewed his book about the Cambrian explosion, you can find that in this previous post.

Further study

The Cambrian explosion lecture above is a great intermediate-level lecture and will prepare you to be able to understand Dr. Meyer’s new book “Darwin’s Doubt: The Explosive Origin of Animal Life and the Case for Intelligent Design“. The Michigan State University book that Dr. Meyer mentions is called “Darwin, Design and Public Education“. That book is one of the two good collections on intelligent design published by academic university presses, the other one being from Cambridge University Press, and titled “Debating Design: From Darwin to DNA“. If you think this lecture is above your level of understanding, then be sure and check out the shorter and more up-to-date DVD “Darwin’s Dilemma“.

Yale computer science professor David Gelernter expresses doubts about Darwinism

How did life begin?
How did life begin?

I had to learn about David Gelernter when I was doing my Masters in computer science. We studied his book “Mirror Worlds”. A few weeks ago, I blogged about his impressions of the difficulty in forming a simple protein by chance – something that naturalistic mechanisms would have to do in order to avoid intelligent agency as a cause in nature. He found it very unlikely. But there’s more!

Recently, my friend Terrell sent me a video featuring Peter Robinson (who hosts the splendid Uncommon Knowledge show out of Stanford University), and three interesting people. First, there was Dr. Stephen C. Meyer, who is one of my two favorite thinkers. I’ve blogged on his work about the origin of life and the Cambrian explosion here many times. Then, there was Dr. David Berlinski, a secular Jewish professor of mathematics, who has studied origins issues. And then Dr. David Gelernter, who teaches computer science at Yale University, and is a legend in computer science research.

Here’s the video: (H/T Terrell)

Here is an article by Jennifer Kabbany in The College Fix about the video.

She writes about his recent Claremont Review of Books article, as well as the interview above:

In May, the Claremont Review of Books published a column by Gelernter headlined “Giving Up Darwin.” In it, he explained how his readings and discussions of Darwinian evolution and its competing theories, namely intelligent design, have convinced him Darwin had it wrong.

In particular, he cited Stephen Meyer’s 2013 book Darwin’s Doubt as well as The Deniable Darwin by David Berlinski. The professor expanded on his views in an interview with Stanford University’s Hoover Institution that was published last week.

Gelernter stops short of fully embracing intelligent design, both in his essay and during his interview. He said in his interview he sees intelligence in Earth’s design, and has no quarrel with ID proponents, but notes the world a mess, its suffering far outweighs its goodness.

“My argument is with people who dismiss intelligent design without considering, it seems to me — it’s widely dismissed in my world of academia as some sort of theological put up job — it’s an absolutely serious scientific argument,” Gelernter said during his interview. “In fact it’s the first and most obvious and intuitive one that comes to mind. It’s got to be dealt with intellectually.”

I found this part the most interesting, since we are seeing so much intolerance from the secular left, whenever anyone disagrees with their dogma:

Gelernter said he likes many of his colleagues at Yale, that they are his friends, but when he looks at “their intellectual behavior, what they have published — and much more importantly what they tell their students — Darwinism has indeed passed beyond a scientific argument as far as they are concerned. You take your life in your hands to challenge it intellectually. They will destroy you if you challenge it.”

“Now, I haven’t been destroyed, I am not a biologist, and I don’t claim to be an authority on this topic,” Gelernter added, “but what I have seen in their behavior intellectually and at colleges across the West is nothing approaching free speech on this topic. It’s a bitter, fundamental, angry, outraged rejection [of intelligent design], which comes nowhere near scientific or intellectual discussion. I’ve seen that happen again and again.”

Gelernter acknowledges “I am attacking their religion and I don’t blame them for being all head up, it is a big issue for them.”

Dr. Gelernter cited three arguments in his article: the origin of life, and the Cambrian explosion, and genetic entropy. In the first two problems, there is a problem of huge amounts of biological information coming into being . We know that software engineers can write code like that, but there is no Darwinian mechanism for writing that much code and that short of a time period. The third problem shows that Darwinian mechanisms not only don’t produce functional code – they actually break it down.

I’ve covered both of the arguments before on this blog, but if you really want the details, you should pick up the books that convinced Dr. Gelernter: Dr. Stephen C. Meyer’s “Signature in the Cell” and “Darwin’s Doubt”. Each book tackles one of the arguments. For the third problem, a good book is Dr. Michael Behe’s “Darwin Devolves”. Even if you just read something about each book, then you’ll know about the arguments for intelligent causes being the best explanation for the history of life on this planet.

Information Enigma: 21-minute video explains intelligent design

Can random mutation and natural selection create new functional information?
Can random mutation and natural selection create new functional information?

I have read and listened and watched a lot of material on intelligent design, but I have never seen so much value packed into such a short lecture. I really hope you’ll watch this and that it’s helpful to you.

Summary:

  • the big question when discussing the origin of life: where did the information in living systems come from?
  • Until 530 million years ago, the oceans were largely devoid of life
  • In a 10 million year period, many new forms of animal life emerged
  • New biological forms of life require new information
  • the discovery of DNA shows that living systems work because cells have information that allows them to build the components of molecular machines: cell types, proteins, etc.
  • can random mutation and natural selection create new functional information?
  • normally, random mutations tend to degrade the functionality of information, e.g. – randomly changing symbols in an applications code does not usually introduce useful new functions, it usually renders what is there non-functional
  • the majority of possible sequences will NOT have functions, so random mutations will more likely give you non-functional code, rather than functional code
  • example: a bicycle lock  with 4 numbers has many possible sequences for the 4 numbers, and only one of them has unlock functionality, the rest have no functionality
  • if you have lots of time, then you might be able to guess the combination, but if the lock as has 10 billion numbers, and only one combination that unlocks, you can spend your whole life trying to unlock it and won’t succeed
  • how likely is it to arrive at a functional protein or gene by chance? Is it more like the 4-dial lock (can be done with lots of time) or the 10 billion dial lock (amount of time required exceeds the time available)?
  • the probability is LOW because there is only one sequence of numbers that has unlock function
  • consider a short protein of 150 amino acids has 10 to the 195th power possible sequences
  • if many of these sequences of amino acides had biological function, then it might be easier to get to one by random mutation and selection than it is with a lock that only unlocks for ONE sequence
  • how many of the possible sequences have biological function?
  • Thanks to research done by Douglas Axe, we now know that the number of functional amino acid sequences for even a short protein is incredibly small…
  • Axe found that the odds of getting a functional sequence of amino acids that will fold and have biological function is 1 in 10 to the 77th power
  • Is that number too improbable to reach by chance? well, there are 10 to 65th atoms in the entire Milky Way galaxy… so yes, this is a very improbable outcome
  • can random genetic mutations search through all the sequences in order to find the one in 10 to the 77th power one that has biological function? It depends on how much guessers we have and how many guesses we get in the time available
  • even with the entire 3.5 billion year history of life on Earth, only about 10 to the 40th organisms have ever lived, which far smaller fraction of the 10 to the 77th total sequences
  • even with a very fast mutation rate, you would not be able to reach a functional protein even with all that time, and even with all those organisms

I was once having a discussion with a woman about the research that Axe did at the Cambridge University lab. He published four articles in the Journal of Molecular Biology. I held out one of the papers to her and showed her the numbers. She said over and over “I hate the Discovery Institute! I hate the Discovery Institute!” Well, yeah, but you can’t make the Journal of Molecular Biology go away with hating the Discovery Institute. JMB is peer-reviewed, and this was experimental evidence – not a theory, not a hypothesis.

We have been blessed by the Creator and Designer of the universe in this time and place with overwhelming evidence – an abundance of riches. For those who have an open mind, this is what you’ve been waiting for to make your decision. For the naturalists who struggle so mightily to block out the progress of experimental science, they’ll need to shout louder and shut their eyes tighter and push harder to block their ears. Maybe if they keep screaming “Star Trek” and “Star Wars” over and over to themselves, they will be able to ignore the real science a little longer.

Walter Bradley asks: what is religion really supposed to be about?

Dr. Walter L. Bradley
Dr. Walter L. Bradley

This lecture is based on the book “Truth in Religion” by famous philosopher Mortimer J. Adler. At the time of writing the book, he was not a Christian, but there is still a lot of value in the book for Christians who are trying to understand what religion should really be about.

About the speaker

The speaker is one of my top 3 favorite speakers of all time in Christian apologetics, Dr. Walter Bradley. (The other two are Dr. Stephen C. Meyer and Dr. Michael Strauss)

Here’s a biography:

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.

You can read more about his recent research on how to use coconuts to make car parts in this article from Science Daily.

The MP3 file is here. (31 minutes + Q&A)

Topics:

  • what is pluralism?
  • what is multiculturalism?
  • what is relativism?
  • some propositions are true culturally – just for certain groups in certain times (cultures)
  • some proposition are true trans-culturally – true independently of what anyone wants or feels
  • Mathematical truth is trans-cultural – it is true regardless of cultural fashions
  • Scientific truth is trans-cultural – it is true regardless of cultural fashions
  • Some truths are not like this – cooking traditions, clothing traditions and greeting traditions
  • These kinds of truths are NOT trans-cultural, they vary by culture
  • The question is – is religion true like math and science, or true depending on the culture
  • Some people think that your religion depends on where you were born or what your family believes
  • Religions make conflicting claims about the way the world really is, so they can’t all be true
  • And these conflicts are at the core of the religions – who God is, how can we be related to him, etc.
  • So if religions convey trans-cultural truth, then either one is true or none are true
  • If they are not trying to convey trans-cultural truth, then they are not like math and science
  • Let’s assume that religion is the same as trans-cultural truth
  • How can we know which religion is true? 1) the laws of logic, 2) empirical testing against reality
  • Logical consistency is needed to make the first cut – self-contradictory claims cannot be true
  • To be true trans-culturally, a proposition must at least NOT break the law of non-contradiction
  • According to Mortimer Adler’s book, only Christianity, Judaism and Islam are not self-contradictory
  • All the others can be excluded on the basis of overt internal contradictions on fundamental questions
  • The others that are self-contradictory can be true culturally, but not trans-culturally
  • The way to proceed forward is to test the three non-contradictory religions against science and history
  • One of these three may be true, or they could all be false
  • We can test the three by evaluating their conflicting truth claims about the historical Jesus
  • Famous skeptics have undertaken studies to undermine the historical Jesus presented in the Bible
  • Lew Wallace, Simon Greenleaf and Frank Morrison assessed the evidence as atheists and became Christians
  • There is a lot of opposition in culture to the idea that one religion might be true
  • But if you take the claims of Jesus at face value, he claims to be the unique revelation of God to mankind
  • Either he was telling the truth about that, or he was lying, or he was crazy
  • So which is it?

Why don’t religious people ask if their religion is true?

People seem to be chicken these days about claiming that their religion is true. It’s easier to say that my religion is true for me, and your religion is true for you – reduce it to personal preferences. So long as everyone is sincere about what they believe, then that’s the most important thing, right?

But it is NOT TRUE that you can believe whatever you want as long as you are sincere – sincerity doesn’t mean that you can’t be mistaken. I can jump off the top of the Sears Tower and be sincere in my belief that I will float down like a feather, but that doesn’t make my belief true. If you want to have a good relationship with God, you have to know things about him, not just have sincere beliefs. You have to know whether he exists and what he is like – really. It’s not enough to have sincere beliefs that are not actually true.

I think that God’s existence and character can be assessed and known based on logic and evidence. I think that God exists independently of whether I want him to or not, and I think that his character and desires are not the same as my character and desires. And I don’t really care what my neighbors think of my disagreeing with them, my goal is not to keep silent and to just get along with them and be happier in my community.

God’s first commandment to us is not to love our neighbor – that’s number two. Number one is to love him. And how can we love him, if we don’t want to know him. And how can we love him, if we don’t tell people the truth about him when they ask us?

That message is not going to win us a lot of friends, but our job as Christians is to tell how and why God stepped into history. Jesus expects us to be his ambassadors and to carry out the task of evangelism faithfully, and to suffer with him and – if necessary – to be rejected like he was rejected.

William Lane Craig debates Austin Dacey: Does God Exist?

Two tough rams butt heads, and may the best ram win!
Two tough rams butt heads, and may the best ram win!

Here is the video and summary of a debate between Christian theist William Lane Craig and Austin Dacey at Purdue University in 2004 about the existence of God.

The debaters:

The video: (2 hours)

The video shows the speakers and powerpoint slides of their arguments. Austin Dacey is one of the top atheist debaters, and I would put him second to Peter Millican alone, with Walter Sinnott-Armstrong in third place. This is the debate to show people who are new to apologetics. The debate with Peter Millican is better for advanced students, and that’s no surprise since he teaches at Oxford University and is familiar with all of Dr. Craig’s work. The Craig-Dacey debate is the one that I give to my co-workers.

By the way, you can get the DVDs and CDs for the first Craig-Dacey debate and the second Craig-Dacey debate and the second Craig-Sinnott-Armstrong debate. The Peter Millican debate is not available on DVD, but the link above (Peter Millican) has the video and my summary.

Dr. Dacey’s 5 arguments below are all good arguments that you find in the academic literature. He is also an effective and engaging speaker, This is a great debate to watch!

SUMMARY of the opening speeches:

Dr. Craig’s opening statement:

Dr. Craig will present six reasons why God exists:

  1. (Contingency argument) God is the best explanation of why something exists rather than nothing
  2. (Cosmological argument)  God’s existence is implied by the origin of the universe
  3. (Fine-tuning argument) The fine-tuning of the universe for intelligent life points to a designer of the cosmos
  4. (Moral argument) God is the best explanation for the existence of objective moral values and objective moral duties
  5. (Miracles argument) The historical facts surrounding the life, death and resurrection of Jesus
  6. (Religious experience) God’s existence is directly knowable even apart from arguments

Dr. Dacey’s opening argument:

There are two ways to disprove God’s existence, by showing that the concept of God is self-contradictory, or by showing that certain facts about ourselves and the world are incompatible with what we would expect to be true if God did exist. Dr. Dacey will focus on the second kind of argument.

  1. The hiddenness of God
  2. The success of science in explaining nature without needing a supernatural agency
  3. The dependence of mind on physical processes in the brain
  4. Naturalistic evolution
  5. The existence of gratuitous / pointless evil and suffering

One final point:

One thing that I have to point out is that Dr. Dacey quotes Brian Greene during the debate to counter Dr. Craig’s cosmological argument. Dr. Craig could not respond because he can’t see the context of the quote. However, Dr. Craig had a rematch with Dr. Dacey where was able to read the context of the quote and defuse Dr. Dacey’s objection. This is what he wrote in his August 2005 newsletter after the re-match:

The following week, I was off an another three-day trip, this time to California State University at Fresno. As part of a week of campus outreach the Veritas Forum scheduled a debate on the existence of God between me and Austin Dacey, whom I had debated last spring at Purdue University. In preparation for the rematch I adopted two strategies: (1) Since Dacey had come to the Purdue debate with prepared speeches, I decided to throw him for a loop by offering a different set of arguments for God, so that his canned objections wouldn’t apply. I chose to focus on the cosmological argument, giving four separate arguments for the beginning of the universe, and on the evidence for Jesus’ resurrection. (2) I reviewed our previous debate carefully, preparing critiques of his five atheistic arguments. In the process I found that he had seriously misunderstood or misrepresented a statement by a scientist on the Big Bang; so I brought along the book itself in case Dacey quoted this source again. I figured he might change his arguments just as I was doing; but I wanted to be ready in case he used his old arguments again.

[…]The auditorium was packed that night for the debate, and I later learned that there were overflow rooms, too. To my surprise Dr. Dacey gave the very same case he had presented at Purdue; so he really got clobbered on those arguments. Because he wasn’t prepared for my new arguments, he didn’t even respond to two of my arguments for the beginning of the universe, though he did a credible job responding to the others. I was pleased when he attacked the Big Bang by quoting the same scientist as before, because I then held up the book, specified the page number, and proceeded to quote the context to show what the scientist really meant.

Dr. Craig is always prepared!
