Why Evolution Cannot Produce a Mind

Yesterday, I posted an article declaring how the mind is a fundamentally different kind of thing than the brain. I wanted to follow up with a couple of possible objections to the mind/brain distinction that people offer today. The first objection is known as emergence and its proponents claim that the mind, while different from the brain, emerges as the brain grows in complexity. Thus the mind is distinct from the brain but it is the evolution of the brain, growing more and more complex, that eventually produced the first mind.

Emergent properties are familiar in both science and philosophy and they basically mean that the whole cannot be described solely by describing its parts. For example, we can talk about a snowflake by its chemical composition. A snowflake is comprised of nothing more than H2O in a solid state. However, describing the chemical bonds that create H2O does not describe a snowflake. The snowflake is something more specific than the chemical reactions of H2O, and thus a snowflake is an emergent property of H2O. Flocks of birds, molds, even societies are used as examples of emergence, where these things are different than the sum of the parts. 1

Materialists will then use this kind of description to say that the mind may be an emergent property of the brain. It exists because the brain's chemistry and electrical pathways are arranged in a specifically complex fashion. Just as the molecules of water or the grouping of people to form a city emerges as a new property that didn't exist in that entity's building blocks, so the mind emerges as a new property of the brain's makeup. Thus, they claim, the mind is a real property but it comes from the physical structure and function of the brain. No soul is required.

The Problems with Emergence

The explanation sounds good, but there are several problems with the claim that the mind is emergent. First, in a complex system where new properties emerge, those new properties fall into the same domain as the system's constituent parts. In other words, any physical emergent system will produce emergent properties that can be described physically. Water may have properties that hydrogen and oxygen lack such as the ability to crystallize into a snowflake. However, a snowflake is still describable by using the chemical language of solid/liquid/gaseous states and crystalline structures. The components are physical and the new property is also physical. Likewise, cities emerge from groups of people getting together and choosing to live a certain way. People are sociological and cities are described sociologically.

The mind however produces mental properties. As we've said, mental properties are non-physical. Therefore there is still a difference in kind in the property one is trying to account for. How does one account for non-physical properties from purely physical substances?

Secondly, emergence runs into the problem of impotence. J.P. Moreland notes that if the complexity of the brain produces a mind "like fire produces smoke or the structure of hydrogen and oxygen I water 'produce' wetness," then the mind is nothing more than an effect of the brain and it therefore has no causal powers. J.P. writes that if this was the case, "mental states are byproducts of the brain, but they are causally impotent. Mental states merely 'ride' on top of the events in the brain." 2

If this is true, then we cannot change our minds, really. We can only dance to the electro-chemical reactions that are happening in our heads. In other words, we have no free will whatsoever! We are simply victims to whatever processes our body and any outside events that we come in contact with cause. We are not making decisions, but our brains, like so many dominoes falling in a row, are just following the rules of chemistry and physics. The mind is simply the smoke, but it's the fire of neurons in the brain that's doing all the work.

The self-refuting nature of a material view of self

Because a purely material origin for the mind leads to determinism, such a description can be seen as contradictory. J.P. quotes from H.P. Owen who says:
Determinism is self-stultifying. If my mental processes are totally determined, I am totally determined either to accept or reject determinism. But if the sole reason for my believing or not believing X is that I am causally determined to believe it I have no ground for holding that my judgment is true or false.3
I think Owen and Moreland are right here. Much like the argument from reason, trying to relegate our conscious awareness to the physical becomes a fool's errand of determinism and contradiction. Such suggestions really don't explain why unique properties of the mind exist and it leads us to conclude that no one really makes any free choices. That's an awful lot to give away in order to escape the necessity of the soul.

The Moral Argument in a Nutshell

Morality is a key component of what it means to be human. The fact that there are at least some standards to which all human beings should adhere is well-recognized across all cultures. Morality is real and must be rooted in an objective reality beyond our natural world.

First, we know that morality cannot be merely a human convention where people agree to behave a certain way.

It differs from other types of societal norms, such as understanding which side of the road to drive on. While driving on the wrong side of the road is illegal, what makes it the "wrong side" is simply a social construct, an agreement between people to ensure safety and a smooth flow of traffic. It makes no sense to say Americans are immoral when we drive on the right side of the road while those in the UK and Australia are behaving morally upright by driving on the left. Those are simply societal norms that help us get about our business.

Therefore, morality cannot be derived from nature or natural law. It cannot be thought of as only stemming from some evolutionary framework to benefit our survival as a species.

The atheist philosopher Michael Ruse clearly understood this when he said that if evolution is true, then morality doesn't really exist. Ruse argued that morality:
"simply does not work unless we believe it is objective. Darwinian theory shows that, in fact, morality is a function of (subjective) feelings; but it shows also that we have (and must have) the illusion of objectivity."1
Ruse goes on to argue that morality is "an illusion foisted upon us by our genes" and that the illusion is the objectivity of moral values. According to Ruse, if morality stems from an evolutionary framework, it is not real, but only a useful fiction. And if it's not real, then it cannot be considered binding for all humanity.

No, morality is a completely different kind of thing. We recognize that a heinous act such as torturing a weaker individual only for pleasure is an objectively evil thing to do—it is wrong for all people across all ages, regardless of whether they thought so or not. Thus, moral laws are considered prescriptive—they are how anyone at any place and any time should behave given a specific set of circumstances. And we can recognize such laws as real, not simply made up to propagate the race.

In order for moral laws to be prescriptive in this way, they must be grounded in something other than a social agreement. Therefore, moral laws must have a source that transcends humanity, that is, God.

So, if there is no God, then there are no real moral values and duties. But, we know moral values and duties do exist. Torturing babies for the fun of it is really wrong. So it stands to reason that God does exist.

Review of the Ken Ham-Bill Nye Creation Debate

Yesterday, Ken Ham and Bill Nye debated their concepts of creation and evolution at Ham's Creation Museum in Petersburg, Ky. I watched the debate live with a group at a local church (you can watch a recording for a few more days here), and given that there were nearly 500,000 streams of the event around the globe, it would be easy to estimate that well over half a million people viewed the exchange. Many have commented on the event, but as someone who has previously participated in a formal debate, I thought I would put down some of my observations here.

The Good

I thought the debate was very well run and it went better than I expected. Both Mr. Ham and Mr. Nye were respectful in tone and were genuine in their approaches. I think each participant understood that this event was important and each wanted to make his best case. CNN's Tom Foreman moderated and did an excellent job as well.

The debate platform was clean and the podiums for the speakers were spaced comfortably for both audience viewing and the television cameras to get a two-shot. (The graphics on the front of the podiums were my favorite part.) Using a pre-submitted set of questions from the audience allowed the Q & A time to flow quickly and more questions were presented in the 45 minute allotment than could be had with a queue in front of microphones.

I thought some of Bill Nye's arguments concerning the ice core evidence for 680,000 of winter/summer cycles and the abundance of species variation that argues against such diversification taking place in only a few thousand years were his strongest points. I thought that Ham did a great job in showing how science education today does hold a bias against a creator, even including a clip from a previous interview Bill Nye did. He was particularly strong when referencing a new study that shows all dogs came from a single ancestor and declaring how changes in finch beaks are variations within an instruction set. He also notes that cave fish "evolving" to have no eyes is not a net gain; there is no new information there. The fish have only lost the capability of seeing. Ham was also bold enough to present the gospel a few times during the evening, which I appreciated.

The Bad

The most unfortunate thing in this debate is that neither debater focused on the actual debate question! At the beginning of the debate, Foreman clearly stated that the debate question was "Is creation a viable model of origins in today's modern scientific era?" Ham was to argue the affirmative and Nye was to take up the negative. Neither person in their initial opening five minute speech nor in their longer thirty minute second presentations built an argument focused on this question. Ham continually claimed that one must start with certain assumptions when trying to understand the past. However, this doesn't address whether or not creationism is a viable model. Several times throughout the night he highlighted scientists who were also creationists, although most of those had specialties that had nothing to do with creationism or evolution at all. If the debate question were "can good scientist hold to a creation model?" this would be prime evidence. Alas, that was not the topic at hand.

Nye actually changed the question when he began his 30 minute presentation. He begins by saying, "Let's take it back to the question at hand. Does Ken Ham's creation model hold up?" What? Is that now the topic of the debate? If so, I wouldn't have bothered watching because I'm not interested in Ham's version. Nye offered several strange lines of evidence, such as the shipbuilding capabilities of Noah and his family. Huh? What in the world does that have to do with creation as a viable model in science? In any account of Noah and the flood, the creation has already been established.

Nye also went off on a tangent about fish reproducing asexually versus sexually with others. He notes how asexual reproduction is less desirous but sometimes necessary (that's a straight line for too many jokes.) But again, how does this prove or disprove the question at hand? Could the fish not be designed for such contingencies? It shows neither evolution nor creation but the fact that certain fish in a certain environment have the capability to reproduce asexually. There are other animals that reproduce asexually, too. This completely misses the question.

Neither presenter provided an actual argument—you know, a series of premises and a conclusion—that I would have expected in a debate. It would have been a much more powerful presentation had the opponents laid out their arguments first and then expounded on them. And it was clear that both presenters were guilty of something I've stressed before: creation conflation.

The Ugly

There were a few missed opportunities in the debate that could have been capitalized on. The first is Nye's claim that if you can find "even one example" of a fossil crossing layers you would change science forever and "the scientists of the world would embrace you." Well, polystrate fossils have been well-documented, and it hasn't led the scientific community to embrace creationism. There are simply new theories that justify the find as a natural, not a supernatural occurrence.

The point that made me laugh out loud, though, was how Nye insisted that scientist WANT to embrace new ideas. We know that scientists resist upsetting their current models, as this 1961 article from Science shows. The more relevant work is that of Thomas Kuhn. In his book The Structure of Scientific Revolutions, Kuhn demonstrates how the history of science is not one gradually increasing understanding of the world, but it is more how a certain model becomes the status quo and is accepted until someone (whom Kuhn labels "an outsider") upsets the status quo by offering a new paradigm. Thus science advancement comes in fits and stages as those who hold the existing model are forced to give way to the newer paradigm.

Two examples of Kuhn's paradigm shifts were items that Bill Nye mentioned in the debate: the emergence of plate tectonics and the abandonment of spontaneous generation after Louis Pasteur's experiments. Another I could add was the emergence of the Big Bang model from the previous steady state theory of the universe. Like the other models, the theory was not met with open arms by the scientific community, but by much resistance. Nye seemed to imply that Fred Hoyle liked the idea, when he actually named it in derision and was one of its most vocal opponents. Though it was first proposed by Roman Catholic priest Georges Lemaître in 1927, it took Wilson and Penzias' discovery of the cosmic background radiation in the 1960's that led it to be the primarily accepted model among cosmologists.

Another wince-inducing point was how Nye tried to assert that the Biblical text was transmitted to us through a method like the telephone game. This is simply, demonstrably false and even non-believing scholars flatly reject such an assertion.

Ham had some egregious moments as well. When he for the third and fourth time referred to his small sampling of scientists who were also creationists, his argument moved from a non-sequitur to a fallacious appeal to authority, and it became annoying from the audience's standpoint. Ham never answered Nye's stronger points above, but simply dismissed them with the rhetorical "how do we know, we didn't see it!" Well, if that's the criteria for knowledge about historical events, then we need to fire all the CSI lab technicians and set the murderers free.

Ham also lost points in my opinion when he was asked if he was provided evidence, would he still believe in God. Instead of beginning with the historical fact of the resurrection of Jesus, Ham stated that everyone has to have certain presuppositions and the Bible was his presuppositional choice. But doesn't that beg the question? Nye similarly begged the question when asked about things like the emergence of consciousness or how the Big Bang happened from nothing. He simply claimed these were "great mysteries" and we should be glad they are there to study.

The final question of the night, "What is the one thing, more than anything else, upon which you base your belief" was offered to both participants and they basically responded the same way they had been all night long. Ham said one must presuppose the truth of the Bible in order to know history and origins. Nye answered that he based his beliefs on the joy and love he receives from the information and the process of science. Their presuppositions are noted, but each is rather subjective. I know that many creationists also feel Nye's excitement and love of scientific discovery. I know there are many other people who presuppose the Qur'an, the Book of Mormon, or some other text as their starting point for interpreting history and creation. Neither answer satisfies a seeker who is honestly trying to make heads or tails out of all this, and while this question may be tangential in itself, neither response helps us answer the question of the debate.

Conclusion

In all, I am truly excited that the interest in this debate was so high. I think there are many, many people who really want to discover the facts that are out there and that we as Christian communicators can find fruitful ground in providing some of those answers. There are a lot of holes left open by the participants in the debate. Let's see if we can go out and close some of them with good evidence.

Of Mice and Men - How Our Assumptions Color Our Understanding

In my time as an apologist, I've come more and more to realize just how much the presuppositions of people will influence their interpretation of facts and truth-claims. All of us carry biases and it is important that we recognize and are sensitive to our own biases as well as those of the person with whom we're discussing things of God.

I was reminded of this just recently. When I used to commute to Los Angeles, I would pass a recycling facility. At one corner of the facility's yard is a large mound of debris that was compiled many years ago. The rubble is weathered and mature weeds grow from the artificial hillside. None of this is particularly worthy of note, except that there is a chain link fence surrounding the pile with both barbed wire and razor wire protecting its cache from any trespassers.

I thought it kind of interesting that a trash heap would be fenced off and protected to such a degree. Letting my mind wander, I thought "What would an archaeologist make of this discovery in a thousand years? He might assume that the contents of that pile were very valuable at one time, seeing as it's so well protected." Of course, I realized that the fence and wire were there to protect wayward explorers from injuring themselves and possibly suing the facility. But if someone didn't have that cultural understanding of our society, they could look at the same evidence I saw and come to a drastically different conclusion.

I further imagined that if this scenario came about the contents of the rubble pile would be cataloged and examined. Academic papers would be written, debates over the importance of this stone versus that one would surface and countless hours would be devoted to rebuilding whatever was supposed to have been originally housed at the site.

A Big Mistake Identifying a Little Animal

Now, this may sound a bit extreme; surely the science of our day is too sophisticated to make such an error! But the skirmish over a little mouse in Wyoming, as reported by the Seattle Post-Intelligencer underscores my point.(1) In 1954, Professor Philip Krutzsch identified a new subspecies of Meadow Jumping Mouse from examining the skulls and skins of several samples. The new species was named the Preble's mouse. In 1998, this study was offered as evidence to the U.S. Fish and Wildlife Service to help list the Preble's mouse as an endangered species, which the agency did.

Now, according to the Post-Intelligencer, "after six years of regulations and restrictions that have cost builders, local governments and landowners an estimated $100 million, new research suggests that the 'threatened' Preble's mouse in fact never existed." The newspaper reports that recent mitochondrial genetics studies, performed by a team from the Denver Museum of Nature and Science show that the mouse is identical to the Bar lodge mouse, a species common enough not to need protection at all.

Now the critic might say that this proves nothing since modern science caught its own mistake. However, I find it interesting that the only way we could have caught such an error is because we have existing specimens today. We're able to do such things as DNA testing. Remember, Krutzsch's original findings were based on skeletal and skin samples and they were considered acceptable at that time as the article points out. If no live samples of the so-called Preble's mouse were around to be tested, I wonder if the error would have been caught at all.

Evolution's Identity Problems

In fact, that's the whole reason for this discussion. Evolution as a field of study is based pretty much on the evidence of skeletal remains. We have some fossilized skin patterns, footprints, and such. But most of all the advances in evolutionary theory are from fossilized bones. If a modern day professor got it wrong about a mouse that he was able to observe, than how much more likely is it that paleontologists make mistakes interpreting fossils. In fact, author Luther Sunderland asked David M. Raup, a noted evolutionist and Curator of Geology at the Field Museum of Natural History at the University of Chicago, about the practice of naming the same creature by different species names when it's found in different period rocks. "He acknowledged that it used to be a very common practice and still occurred… it was done purposely because of an a priori theoretical mode, but he thought most of these had 'been cleaned out now'."(2)

So here we have evidence that the bias of the scientists come into direct play when they seek to identify a new species. In fact, Raup noted that many times this was done on purpose to try and make the evidence conform to the theory instead of the other way around. He later tells Sunderland that "approximately 70 percent of species described are found to be the same as existing species, so 70 percent of the new species named should not have been, either through ignorance or because of the rules used by taxonomists."(3)

As the debate over evolution continues to heat up, Christians have recurrently been accused of ignoring the evidence because of their beliefs. Is this charge true? Perhaps in some cases. However, the history of paleontology shows just as large a bias on the part of the evolutionists. So, the next time you are discussing the issue with a friend or colleague, make sure you're sensitive to the assumptions that lie behind the assertions. Their facts may be as tenuous as a rat in a trap.

Why the Origin of Life Requires a Creator


How did life arise on earth? What are the key elements we need to focus on when talking with an evolutionist? What questions remain unanswered? Listen to all four parts of this recent podcast that focuses specifically on the beginning of life and explains why, given the evidence, belief in a creator makes the most sense.

J.P. Moreland to Young Christians: "Don't let anybody bully you"

Dr. J.P. Moreland recently gave a talk on why he doubts the neo-Darwinian model of all life arising from purposeless natural processes. I highly recommend the video. At the end of the talk he offered these words of encouragement to young Christians who may not be steeped in apologetics arguments:
"Don't let anybody bully you. I meet Christians all the time who think all the smart people are on the other side. That's not true. And if you don't know how to defend your faith, that's OK; we've got people who do. And we're community; we don't all have to know how. Because we have different roles to play. But we have people in our community who are as smart as the people on the other side and we know what we're talking about. You don't need to let anybody bully you because what the Scriptures teach at the end of the day makes sense and they're reasonable and we have nothing to be ashamed of in believing in the Creator God that we believe in."
J.P. is right. We have very smart people with incredibly strong arguments who are able to show the Christian worldview is at least as reasonable as modern secular viewpoints, if not more so. I know that there is a vast amount of data one must sift through in order to truly understand the points in question, but all Christians should be aware that we do have the goods, and they can walk confidently knowing that Christianity is an intelligent faith.

Evolution and the Indian Rope Trick

Last month, I was privileged to be a part of the Great God Debate II: The Origin of Life, which pit atheist Michael Ruse against intelligent design advocate Fazale Rana. In Dr. Ruse's opening statement, he made an argument on what he has labeled the "fallacy of selective attention or illicit focus." It was probably Ruse's most powerful point and he admitted it carried the bulk of his reasoning for why the idea of intelligent design can be dismissed.

Ruse showed a picture of an Indian guru climbing a rope suspended into the sky. This is a well-known illusion called the Indian rope trick. He then states:

"You look at this and you say 'Oh my God! Newton was wrong! Gravity doesn't work.' Hang on a minute, hang on a minute. Of course gravity works. We don't just look at the Indian rope trick in isolation. We take it in context. We ask ourselves, 'Why would we say that the Indian rope trick must be a trick and not magic?' Why do we think that Newton's laws do hold in a case like this? Why do we think that there's something fishy going on here? And the answer of course is that we're not just judging the Indian rope trick on its own, but against the background knowledge that magic simply doesn't work and that Newton's laws do."
(You can see Ruse make this argument here.)

Ruse follows up this analogy by summarizing his argument thusly:
  • We don't just look at it (the cell) and say "Oh my goodness, it is so complex and works so well. It must be designed in a hands-on fashion."
  • We judge the cell against all our knowledge, and that includes our knowledge of evolution through natural selection at the macro level.
Now, I think Ruse is onto something here. He's right that we cannot take the cell in isolation. However, I think when studied carefully his argument actually works against him.

Ruse assumes that when judging the Indian rope trick, all we need to do is appeal to Newton's laws. That's not exactly true. We appeal to our past experience of the world and we find that we never experience a violation of gravity. It is our experience that things, without any external force, will fall to the earth. However, that is exactly the argument that intelligent design proponents are making! In our experience, when we see very complex, information -bearing systems, we understand that an intelligent agent is the cause of those systems. It would be the extraordinary thing to find an information-carrying code that is complex but arose naturally. Cryptographers and archaeologists base their vocations on this principle.

If we expand Ruse's level of examination beyond the cell, we have the same issues. If we look to life, we never see life arising spontaneously from non-living material. Louis Pasteur proved this and we bank on it every time we go to the grocery store. I don't know about you, but I don't want to find new life in my peanut butter jar!

If we judge the cell against ALL knowledge, then our past knowledge of life coming from life and complex information-bearing systems coming from minds are the equivalent of our experience of our past knowledge of how gravity affects ropes and people. It is the evolutionist that seems to be seeking an Indian rope trick explanation for what we now know to be true. And I, for one, am not buying it.

Falsifiability and Intelligent Design

The idea of falsification is rooted in the scientific method. Experiments are attempts to see if the scientist's hypothesis will break under certain circumstances.  Basically, the scientist is trying to falsify his hypothesis—his description of how natural laws will behave given a set of conditions. This is exactly what Galileo did when he wanted to test the idea that gravity pulls on everything with the same acceleration. By dropping two cannonballs of different weight from the Leaning Tower of Pisa and demonstrating that they landed simultaneously, Galileo showed that his theory was correct. If the heavier ball were to have hit the ground first, Galileo's theory would have been falsified and therefore abandoned for some other explanation.

Because of this power to confirm or disprove theories about the way the natural world works, falsification is taken very seriously by the science community. In fact, some scientists hold that without the ability to falsify a theory, you are simply not doing science. 1 Indeed, this charge is very often leveled against those who resist the idea of Neo-Darwinian evolution2, but instead hold that life displays in its existence and construction an underlying intelligence. Wishing to dismiss any idea that a source other than a natural one could produce life, those who claim science as thier gude will simply dismiss any claims or evidence for intelligent design with a wave of a hand.  "It's not falsifiable" they charge and quickly dismisses any evidence the theory provides.3 But they aren't being consistent in the application of their citeria! In making such an objection, the objector has undercut his own view that evolution is science.

If the criteria of falsification is the determining factor of what separates science from non-science, then evolution should be falsifiable; it should be able to be proven incorrect.  But just what does that look like? With Galileo, we know that there's a positive result for his theory (both balls hitting the ground simultaneously) and a negative result (the heavier hitting the ground before the lighter). So, if we speak of evolution as a process NOT created or guided by an intelligence, and such a definition is considered science, the what should we look for to show that the theory is falsified?  Isn't it the fact that life shows intelligence in its creation instead of randomness?

Intelligent design and Neo-Darwinian evolution are two sides of the same coin, the coin of origins. To choose one side means the other doesn't show itself.  But both sides must exist for the coin to exist! Those who hold to scientism would tell you that you must choose your scientific theory on the development of life from a coin that has only one side—there is no other side that's a legitimate choice. If the concept of falsification excludes intelligent design from being considered science, then by extension, it must also exclude it opposite, the theory of evolution.  This criterion applies to both equally, which means they are either both considered such or neither are. Scientism would have you believe in one-sided coins, but thoughtful people should never fall for such ridiculousness.

Can We Be Equal on Evolution's View? (video)



"If evolution is true, then what makes all people equal to begin with?"

Here's a quick video clip to share with young people that will help provoke their thinking. I discuss the problem of anchoring equality of persons from an evolutionary viewpoint and how the early 20th century eugenics movement was the natural outgrowth of this view.

Top Ten Neglected Books for Apologists - #3 Darwin's Enigma

Darwin's Enigma by Luther SunderlandEvolution is always a hot topic in apologetics circles and I've seen a true renaissance in the way Christians have approached the myriad of issues surrounding the claim that the entire diversity of life on this plant derives from a single organism plus chance mutations honed by natural selection. Such stalwarts as Phillip Johnson, Stephen Meyer, William Dembski, and Michael Behe are familiar to most who deal in this subject matter.

However, in 1984 the phrase intelligent design had yet to be coined and Phillip Johnson was a full nine years away from publishing his landmark Darwin on Trial. But it was this year that Darwin's Enigma by Luther Sunderland was first published, a remarkable book in many respects. This still stands as one of my favorite approaches to examining the evidence for the neo-Darwinian model that is offered as the only rational viewpoint by the scientific establishment.

Initially entitled Darwin's Enigma: Fossils and Other Problems, Sunderland takes a careful look at the story of evolutionary development offered as fact in school textbooks and compares it to the evidence that paleontology has actually uncovered.'The main reason I like the book so much was that Sunderland's approach was to find some of the primary people working with the evidence of the fossil record and get them to comment specifically as to what the evidence shows. He writes:
In December of 1978 the New York State Board of Regents directed the New York State Education Department to do a detailed study of how theories on origins should be treated in a revised version of the state's Regents Biology Syllabus. As part of their study they invited the author to supply pertinent scientific information to the Bureau of Science Education which was conducting the study.
During the next year the author conducted taped interviews with officials in five natural history museums containing some of the largest fossil collections in the world. The interviews were with Dr. Colin Patterson in London; Dr. Niles Eldredge in New York City; Dr. David M. Raup in Chicago; Dr. David Pilbeam in Boston; and Dr. Donald Fisher, state paleontologist at the New York State Natural History Museum. Written transcripts of the interviews were given to the New York State Education Department for use in their study on origins.
In these interviews, the paleontologists were questioned in detail about the nature of the fossil record from the deepest deposits containing fossils to the most recent. Typed transcripts of the five interviews were then sent to the interviewees for editing. All but Dr. Patterson made editorial corrections before they were published for use by educators in various states.
This book presents the substance of these interviews through the use of short excerpts and summaries of the replies to the questions.[1]
Because this was well before the rise of the intelligent design movement, and because it had the auspices of the New York state educators, those interviewed seemed to be very candid in their replies. I would doubt that now, given the political heat the subject has taken on, any respondent would answer as freely as the paleontologists did here. It was truly a once-in-a-lifetime opportunity.

So, what kind of information did the experts provide? One famous quote appearing in the book was given by Colin Patterson, noted paleontologist at the British Museum. In a rather excerpt from a letter, Patterson writes, "I fully agree with your comments on the lack of direct illustration of evolutionary transitions in my book. If I knew of any, fossil or living, I would certainly have included them." P atterson later summed up his statement by saying "If you ask,'What is the evidence for continuity?' you would have to say, 'There isn't any in the fossils of animals and man. The connection between them is in the mind.'"[2]

These are the true nuggets of Darwin's Enigma and they truly help people separate the conjecture of the neo-Darwinian model from the evidence that we have.'Certainly, in the thirty five years since the original interviews were conducted more evidence has emerged.'But although we have more fossils, we haven't found much that answers the questioned Sunderland posed any differently. No one has settled the gradualism versus punctuated equilibrium issue.

Darwin's Enigma is a great read and will help you understand some of the assumptions that evolutionists make as they seek to explain the incredible variety of living entities on our planet without invoking a creator. The best part about all of this is that the entire book is available to read online for free. Rendered in html, you can access it here.

Top Ten Neglected Books for Apologists - #5 The Edge of Evolution

The Edge of EvolutionEvolution is a subject that definitely causes a stir. It holds an overwhelming acceptance rate in the scientific community while its adherents make up only 39% of the American public.1 Ask about teaching evolution in schools and you will get a vast array of responses, some of which are very passionate for their positions. Even the way evolution is defined, as I've written before, is controversial. The term has been stretched and shaped to fit whatever its user hoped to prove.

 Much of the confusion and battle on this topic has to do with rebuilding models. All of the neo-Darwinian synthesis models rely on gradual changes over many millions of years, which means that one must infer what changes occurred and why. The evolutionary biologist inserts his own conjecture into his explanation because there is no way he could have observed the development of, say, a new species of homo from a more primitive ancestor. Observation and data could help remove some of the conjecture from what may have happened, but how could we get such data?

That's why my next book in our list of Top Ten Neglected Books by Apologists is an important one. Michael Behe's The Edge of Evolution is one of the few books tackling this subject with hard, observable evidence. Behe, a professor of biological science at Lehigh University, made a huge splash in the intelligent design community with his ground-breaking Darwin' Black Box. Here, he follows up that work by looking specifically at the claim that "life on earth developed over billions of years by utter chance, filtered through natural selection." This book is different though, in that Behe notes that genetic mutational change preserved through natural selection is observable. If you have a large enough population that replicates quickly, you can look at if the population's genetics adapt to new environments and more importantly see if it created new features in the organism.

 In the book, Behe selects three very good candidates that provide data for us to follow: malaria, HIV, and e. Coli. Viruses and bacteria will reproduce on the order of millions in just a few days, and we know that each can evolve resistances to antibiotics. They have the added benefit of holding a much higher rate of genetic mutation that our cells do. Thus, they provide a perfect model to observe in a relatively short time how genetic mutation provides new benefits. But the key here, as Behe shows, is that while these and other more complex species (such as Behe's use of Antarctic fish whose blood doesn't freeze) can have genetic mutations produce some beneficial effects, it always comes at a loss of some other beneficial function. Behe offers the fact that malaria, which it can develop resistance to certain drugs, cannot evolve to overcome those with sickle cell anemia. Further, these changes are limited to relatively small differences. They cannot create entirely new functional systems.

The Edge of Evolution contains some real numbers science can use when looking at the possibility of genetic change. When calculating factors for change, one must take into account how long it takes an organism or species to create a new generation, how many offspring it has, and its rate of genetic mutation. Each of these is known and uncontroversial. Therefore, scientists can observe the beneficial effects of change in something like a malarial virus or an E. Coli bacterium and see if new functions are actually being created, or if functions are merely being broken. Behe also extrapolates how much time would be required to accumulate enough changes to make new features in more complex mammals. As you can expect, the conclusion is not good for the blind watchmaker hypothesis.

  The Edge of Evolution is not a tough read, but there is some science in it. The biggest point the book has going for it is the observable data. Good science should be about the numbers we see, not the numbers we hope to see, and I think Behe here does a great job bypassing some of the conjecture and providing solid evidence that the neo-Darwinian model simply doesn't calculate.

The Origin of Life Matters in the Debate on Evolution

There's an old joke which is a favorite of mine. During World War II, the German U-boats were devastating the English efforts by targeting troop ships and disrupting the British supply chain. Supposedly, Churchill was apprised of the situation and asked what could be done to combat these unseen and therefore uncatchable threats. "Simple," Churchill replied. "Boil the seas and the boats will have to surface. Then our fighters can manage them easily." The officers replied incredulously, "How are we supposed to do that?!" Churchill replied, "Look, I supplied the idea; the rest is an engineering detail!"

In my last post, I discussed how many who hold to a neo-Darwinian view will quickly dismiss questions about the origin of life when discussing the viability of that evolutionary model. As I showed there, it seems that the origin of life does really come into play even in the literature of those wishing to promote an evolutionary paradigm, such as the National Academy of Sciences. However, this doesn't really answer the objection offered that the origin of life cannot be used as evidence against evolution since the former is focused on the beginning of life and the latter assumes life already exists and simply seeks to address the diversity of life in the world. Fair enough, let's then address this objection directly.


One of the primary goals for folks like Richard Dawkins and those who support his Blind Watchmaker hypothesis is to show that the incredible diversity of living beings throughout history has been the result of random mutations coupled with specific environmental factors that would cause some of these mutations to remain, since they provide an advantage to the organism. In other words, we are looking at random mutations and natural selection. But, natural selection assumes that there's something to act upon. If there are no mutations, or if the mutations are not wide enough to cause sufficient variation so that natural selection can make a selection, we don't get any change. So, the next question would be, in looking at the diversity of changes and the time allotted, could natural selection do all that work, considering it must first wait upon a random mutation that is also beneficial? This then prompts more questions.

As we start to think through all the questions that this model provokes, one can see that the model must get increasingly complicated. But, a fundamental issue hasn't been addressed—where did the stuff come from to modify in the first place? Not only can natural selection not act when there are no changes, it cannot act if there is no life. That's simple. If I were to go to an auto show and see a new experimental car made out of some unique alloy and ask where did that come from, telling me whether it was put together by robots or by hand doesn't answer my question. My question is who thought it up and how did they develop the new material. The origin of the vehicle is as much a focus of the question as the assembly.

Similarly, when we ask about the origin of life on the planet, taking us back to just a single cell and then looping through a vastly complex set of parameters obfuscates the question of what is necessary for such a theory to begin to function. If random mutations can't start, then they can't help us anymore than the motivations for surfacing in a sub when the seas are boiling. The complexities of forming life from non-life are so much bigger than the changes needed to get from one life to another that if you answer the first, the second would follow in line. It's not much of a stretch to say that if God could create life, then He could create it with diversity. But if we only limit ourselves to genetic mutations and natural selection, we've really not provided an answer. You can draw up battle plans for targeting U-boats once they surface all you want, but until you can boil the seas, they won't provide you with any advantage.

Is the Origin of Life Part of the Evolution Discussion?

Whenever the subject of evolution comes up, you can usually find a lot of fuzziness in the arguments. As I and many others have noted before, the word "evolution" is itself a very slippery term, that can be used much like Silly Putty—shaped and molded to fit the interlocutor's need. Because of this, I usually like to avoid the term for serious dialogue and instead label the discussion as the fairly precise neo-Darwinian synthesis (which is a mouthful!) or the even more precise blind-watchmaker hypothesis. This latter term points specifically to Richard Dawkins' model outlined in his book The Blind Watchmaker.

However, even here there can be stumbling blocks.  Take for example the problem of abiogenesis. I see many of those supporting the blind watchmaker model object when the discussion starts to focus on the origin of life. Here's a recent example:

Here's the thing, Lenny: if you don't even know what evolution is, what business do you have arguing against it? You're confusing your own concepts! Macroevolution would be change at or above the species level. You're talking about abiogenesis, which is a separate theory from the theory of evolution.

In one sense, the objector is right – Charles Darwin's On the Origin of Species doesn't address the creation of life from non-living material.  He specifically focuses on the variations of species we see today from a common ancestor. However, in the public sphere and even within scientific circles, I think this objection is disingenuous. There are two primary reasons for this: 1) those supporting evolutionary theory lump abiogenesis into their discussions and 2) descent with modification can't get started until life exists.

For an example of the former, let's take Richard Dawkins, in "Why There Almost Certainly is No God" wrote:

Whether my conjecture is right that evolution is the only explanation for life in the universe, there is no doubt that it is the explanation for life on this planet. Evolution is a fact, and it is among the more secure facts known to science. But it had to get started somehow. Natural selection cannot work its wonders until certain minimal conditions are in place, of which the most important is an accurate system of replication — DNA, or something that works like DNA.

It seems that Dawkins is lumping the "explanation for life" with evolution.  Any explanation needs to include its origin as Dawkins subsequently makes clear. But Dawkins isn't the only one.  The National Association of Biology Teachers has an "NABT Position Statement on Teaching Evolution" at its website that begins:

The frequently-quoted declaration of Theodosius Dobzhansky (1973) that "Nothing in biology makes sense except in the light of evolution" accurately reflects the central, unifying role of evolution in the science of biology. As such, evolution provides the scientific framework that explains both the history of life and the continuing change in the populations of organisms in response to environmental challenges and other factors.

Again, lumping the history of life with its divergence doesn't clarify the issue. Lastly, we have the esteemed National Academy of Sciences, who in their book The Search for Life's Origins: Progress and Future Directions in Planetary Biology and Chemical Evolution (1990) include a chapter entitled "The Evidence for Biological Evolution." The chapter holds a description of abiogenesis and leads straight into simple to complex transitions of life.  They then devote another chapter to the dismissal of any creationist perspectives.  It seems the National Academy of Sciences sees no problem in blurring the line between abiogenesis and evolutionary progression. Therefore, I think it's fair to include both in the discussion.  Again, if I'm trying to discuss it the way the proponents of the model do, then they certainly bring the origin of life into the debate.  That makes it fair game.

Next time, I'll address more fully the second point that descent with modification can't get started until life exists.

How to Answer the Evolution Question

There's been an interesting turn in how the origins debate has affected the upcoming presidential race. For the first time, candidates' views on evolution are being made center stage in debate forums and interviews. Tim Pawlenty was asked by NBC news anchor Tom Brokaw about his position on teaching intelligent design and whether "creationism has the same weight as evolution." Likewise, during the South Carolina debate, Juan Williams asked Pawlenty if he equated "the teaching of creationism with the teaching of evolution, as the basis for what should be taught in our nation's schools?" Michelle Bachmann's comments at the Republican Leadership Conference stating that she supports intelligent design in the classroom were quickly highlighted in CNN as a stand-alone issue.


It seems that some in the media are really trying to make the evolution question a driving issue of the election. This is interesting, and quite a departure from previous presidential campaigns. As Jay Richards and David Klinghoffer noted "Evolution is the speed trap of presidential campaigns. Though a president doesn't have much influence over state and local science education policy, reporters lie in wait for the unwary candidate, ready to pounce with a question he's poorly prepared to answer yet that is important to millions of voters ." They're right, and I've been intrigued to see how this plays out on a national stage.

Of course, political reporters have been showing their ignorance on the issue. First, the word "evolution" has always proven to be wiggly. As this article shows, there are at least eight different meaning poured into the word, which makes it very hard to discuss with specificity. Also, reporters seem to think that intelligent design and creationism are synonymous. They aren't. There are many in the ID movement who even believe in some form of common descent. Lastly, as I've talked about here before, there's a huge amount of creation conflation going on - mixing the age of the universe with its cause.

Now, I don't usually give advice to political candidates of any stripe. However, it strikes me that there are many people that may be questioned or pressured by local educational organizations as to why they rebel against teaching evolution alone in the classroom. Here I believe is an intelligent, reasonable and completely supportable answer that I would offer if asked:
It is my understanding that the scientific method requires not only that one come up with a hypothesis to explain the cause and effect relationship of any set of events, but an effort should be made to falsify that hypothesis by testing or research of some kind. 
Falsification is key to the method. Hypotheses that cannot be falsified are not considered science.

Therefore, if the 'blind watchmaker' hypothesis of all life developing from a single source is a scientific one, then it too should be held up to falsification. In order to do science as science, we must teach what the falsification of the hypothesis would look like. The only way this particular hypothesis can be falsified is if we can find evidence that life exhibits intricacies that could not have developed via random mutations perpetuated through natural selection. In other words, we should see if the diversity of living systems show themselves to be too complex to stem from only unintelligent processes.

Are You Guilty of Creation Conflation?

"You are worthy, O Lord, to receive glory and honor and power; for You created all things, And by Your will they exist and were created." -Rev. 4:11



One of the primary aspects of God revealing Himself to man is so that man can properly worship Him and begin to understand the glory that is due God. He accomplishes this through two primary means: general revelation in His creation and specific revelation in scripture. Scripture, though, continually points back to God's creation as evidence for why He is worthy of worship, so creation plays a unique role in our understanding of theology.

The fact that creation is key to our understanding of God has become increasingly evident in the escalating attacks against the doctrine by skeptics and secularists. Simply put, if God exists, then we are obligated to obey Him. Creation argues for the existence of God (see here); therefore those seeking to be under no obligation to God will seek to undermine the fact of His creation. This should be the point where Christians need to focus their dialogue, since it is the claim most easily demonstrated as false.

Because the stakes are high, the discussion of these topics can quickly switch from a reasoned attempt to understand the positions to one of pigeon-holing, name-calling and general ill-will. Unfortunately, this even happens between Christian brothers. As James said, we shouldn't seek to quarrel in such a way with our brothers (James 4:1 ff), but we should seek God's wisdom; a wisdom which is "pure, then peaceable, gentle, willing to yield, full of mercy and good fruits, without partiality and without hypocrisy. Now the fruit of righteousness is sown in peace by those who make peace" (James 3:17-18).

On the Doctrine of Creation, Distinctions Matter

There are many different ways Christians understand the creation story, but there seems to be a lot of confusion in this area on all sides. People begin to conflate (that is mix up or assume the same meaning) between very distinct aspects of creation. They will assume that if you hold to intelligent design you must believe in a young earth, or if you think that there was a Big Bang you reject the biblical creation account.  It is vital in the study of the doctrine of creation to keep this in mind – we need to distinguish between the cause of creation, the method of creation and the timeline of creation. In other words, creation ex nihilo, the Big Bang, the age of the universe and evolution are all different things and believing in one doesn't mean you believe in another.

The Cause of Creation

The cause of creation deals with the ultimate starting point of what we see in the universe. Causes answer the questions of "why does this exists rather than not?"  Some examples are:
  • "Why did the Big Bang bang?"
  • "Why are humans fundamentally different from animals?"
  • "Why is it that the laws of the universe just happen to be so delicately balanced for life?"
  • "Where would the information necessary for DNA to work come from?"

The Method of Creation

The method of creation deals with the development of the world and us as we see it today. It may be that God creates something (such as the nation of Israel), but He chooses a certain method in developing that creation, like the leading of Moses, Aaron, the wandering in the wilderness, etc. Methods answer the questions of "how did this get to be the way it is?" Some examples are:
  •  The diversity of languages may be traced back to just a few common tongues.
  • "When God spoke, did the world just pop into place fully formed or did it coalesce?"
  • "Did God create man uniquely or did He use some natural processes?"

The Timeline of Creation

The timeline of creation deals with the duration of the creation event or events. Was it instantaneous or was there a becoming over a period of time?  Obviously both Adam and Eve were not created instantaneously. Adam was created first and Eve at some later point in time. Duration answers the questions of "How long would method X take to be accomplished according to God's working?" Some examples are:
  • How long was Genesis 1:3?
  • "Did God take one hour, ten hours, or many millennia to create all the fish and the fowl?"
  • "What is meant by the word 'day' in Genesis 1?"
It is unfortunate that too many times I see Christians make fundamental mistakes in swapping these categories, as though they are the same things. Belief in a Big Bang is not the same thing as a belief in evolution. It is not even the same thing as a belief in an old universe. There may be implications that one belief has upon another, but we need to be more careful in our understanding of each of these categories when we begin to discuss these issues with both fellow believers and with skeptics.  It is only the first issue—the cause of creation—that becomes the essential component in the discussion. When discussing God with non-believers, we need to focus our attention on that first. The other two points are important, but they are more "within the family" discussions that can take place in a different setting.

Scientists Clinging to Blind Faith for All to See



I've had several recent discussions with folks who hold that science is superior to religion because science is all based on experimental evidence and facts while religious people just cling to "blind faith." Richard Dawkins recently reiterated this view in a debate held in Mexico City when he made the statement:
[Those who believe in God] like to point to the origin of the universe and say ‘Well, science can’t explain the Big Bang or scientists can’t explain where the laws of physics come from.’ Physicists are working on that. That’s what scientists do. They don’t lie down and pathetically say ‘Oh, we don’t understand it so God did it."
Somehow, those who hold to this view seem to forget that scientists are people, and as such they are subject to the same faults and biases as the rest of humanity.  Nowhere is this illustrated more clearly than in a recent panel discussion of leading scientists on defining life (see video below).  Held at Arizona State University and hosted by The Science Network, this panel was comprised of luminaries such as Dawkins, world-renowned genome expert J. Craig Venter, Nobel laureates Sidney Altman and Leland Hartwell, NASA planetary scientist Chris McKay, and physicists Paul Davies and Lawrence Krauss.  A stellar group to be sure.

The discussion starts by moderator Roger Bingham asking if it is necessary for us to agree on a proper definition of life before we go looking for it in space, so that we can know what we're looking for. McKay almost flippantly dismisses the idea and says we should just start looking! Imagine using that same criteria in medicine — we don't need criteria as to whether a person is still alive, we'll just make it up as we go! This is why excluding philosophers from these discussions is so detrimental.

But the more interesting parts happen starting around the 9:00 mark of the video. As Evolution News pointed out, Dawkins and others have claimed that all life uses the same DNA vocabulary for living creatures. In the video, Venter disagrees with this statement and says that science is showing the concept of all life stemming from one standard DNA vocabulary is not accurate. "The tree of life is an artifact of some early scientific studies that aren't really holding up...So there is not a tree of life." (See the article linked above for the specifics on this claim.) Dawkins is aghast at the suggestion and Paul Davies tries to understand how this could be, but Venter sits calmly and confidently by his statement. This is a pretty earth-shattering admission by Venter, but it's not my main point.

Dismissing Scientific Evidence in the Name of Science

The very next question to the panel is if science were to discover the origins of life and the origin of consciousness, would that sway religious believers or would they continue to cling to their concepts? Dawkins and Krauss both respond that it wouldn't matter; religious people are going to believe what they've been "indoctrinated in childhood" to believe. Dawkins even says that "Well, it obviously ought to have the effect that the questioner says, but I don't think it will." Immediately after that exchange, Chris McKay at the 14:50 mark states that he doesn't believe Venter's view that the tree of life is obsolete, but he still holds to Dawkins' 1980's claim that all life uses the same genetic vocabulary.

I want you to catch that. McKay, whose specialty is geophysics and not genetics, is dismissing the findings of one of the pre-eminent geneticists in the world because he doesn't like where it would take him. The scientist is ignoring the findings of science because the findings threaten his views on the origins of life. McKay is guilty of exactly what Dawkins and Krauss were poo-pooing religious believers about!  As the Evolutionary News article points out, we know that Mycoplasma DNA uses the UGA codon not as a stop as in human genes, but to code for the amino acid tryptophan.  That's like the difference between the saying "Mama die!" in English and saying "Mama die!" in Dutch, which means "Mom, I want this one!" It's a different vocabulary, a different message.

So, the next time you hear that scientists are bias-free and  objective while religion leads to only blind faith, don't you believe it.  The evidence is available for all to see.
