Creation and Evolution in the Schools

A few years ago it was "Creation Science" they were trying to teach in the schools.

Creation Science was an attempt by fundamentalist Christians to give the Genesis account, as interpreted by them, a scientific veneer.

But it was only that -- a thin surface -- and any student who actually believed that Creation Science had anything to do with science would have been educationally crippled.

Now the controversy is between advocates of the theory of Intelligent Design vs. strict Darwinists. And some people want you to think it's the same argument.

It isn't.

What Is "Intelligent Design"?

My first exposure to Intelligent Design theory was Michael Behe's book Darwin's Black Box: The Biochemical Challenge to Evolution. While disavowing any Creationist agenda per se, Behe pointed out serious problems in the strict Darwinian model of evolution.

Basically, Behe's approach was this: Complex systems in advanced organisms depend on many biochemical steps, all of which must be in place for the system to work at all.

So how, Behe asked, could such a complex system have evolved, if the only method available was random variation plus natural selection?

It would be impossible to believe that the entire series of steps in the complex system could randomly appear all at once. But any one step along the way, since it does nothing by itself, could not give the organism that had it any competitive advantage. So why would each of those traits persist and prevail long enough for the complex system to fall into place?

Behe's conclusion is that since complex biochemical systems in advanced organisms could not have evolved through strict Darwinian evolution, the only possible explanation is that the system was designed and put into place deliberately.

In other words, though he shuns the word, complex systems had to have a creator -- they have to be intelligently designed.

The Darwinists Reply

The Darwinist answer was immediate. Unfortunately, it was also illogical, personal, and unscientific. The main points are:

1. Intelligent Design is just Creation Science in a new suit (name-calling).

2. Don't listen to these guys, they're not real scientists (credentialism).

3. If you actually understood science as we do, you'd realize that these guys are wrong and we're right; but you don't, so you have to trust us (expertism).

4. They got some details of those complex systems wrong, so they must be wrong about everything (sniping).

5. The first amendment requires the separation of church and state (politics).

6. We can't possibly find a fossil record of every step along the way in evolution, but evolution has already been so well-demonstrated it is absurd to challenge it in the details (prestidigitation).

7. Even if there are problems with the Darwinian model, there's no justification for postulating an "intelligent designer" (true).

Let's take these points in turn:

1. You have to be ignorant of either Creation Science or Intelligent Design -- or both -- to think that they're the same thing. Creation Science is embarrassing and laughable -- its authors either don't understand science or are deliberately deceiving readers who don't understand it. Frankly, Creation Science is, in my opinion, a pack of pious lies.

But the problems that the Designists raise with the Darwinian model are, in fact, problems. They do understand the real science, and the Darwinian model is, in fact, inadequate to explain how complex systems, which fail without all elements in place, could arise through random mutation and natural selection.

If Darwinists persist in trying to tar the Designists with the Creation-Science brush, then it is bound to appear, to anyone who has actually examined both, that the Darwinists are trying to deceive us. (They're apparently counting on most people to not care enough to discover the difference.)

2. Real science never has to resort to credentialism. If someone with no credentials at all raises a legitimate question, it is not an answer to point out how uneducated or unqualified the questioner is. In fact, it is pretty much an admission that you don't have an answer, so you want the questioner to go away.

3. Expertism is the "trust us, you poor fools" defense. Essentially, the Darwinists tell the general public that we're too dumb to understand the subtleties of biochemistry, so it's not even worth trying to explain to us why the Designists are wrong. "We're the experts, you're not, so we're right by definition."

Behe and his group don't think we're stupid. They actually make the effort to explain the science accurately and clearly in terms that the lay audience can understand. So who is going to win this argument? Some people bow down before experts; most of us resent the experts who expect us to bow.

The irony is that there are plenty of Darwinists who are perfectly good writers, capable of explaining the science to us well enough to show us the flaws in the Designists' arguments. The fact that they refuse even to try to explain is, again, a confession that they don't have an answer.

4. When Darwinists do seem to explain, it's only to point out some error or omission in the Designists' explanation of a biochemical system. Some left-out step, or some point where they got the chemistry wrong. They think if they can shoot down one or two minor points, then the whole problem will go away.

They ignore several facts:

The Designists are explaining things to a lay audience, and Behe, at least, tells us up front that he's leaving out a lot of steps ... but those steps only make the system more complex, not less.

The Designists are working from secondary sources, so they are naturally several years behind. Of course a scientist who is current in the field will understand the processes better, and can easily dismiss the Designists as using old, outmoded models of how the systems work.

What they never seem to show is how the new understanding reveals a system that is not complex after all, one in which each step in the process confers independent benefits on the organism and therefore could have evolved through random mutation and natural selection alone.

They don't do this because the current findings rarely reveal a simpler process than was previously thought. Almost invariably, they find that the system is more complex and therefore harder to explain, and therefore the Designists have even more of a point than they thought.

5. The church and state argument is deliberately misleading. First, the Designists are not, in fact, advocating "God." They are very careful not to specify who or what the Intelligent Designer might be. So they are not advocating for any particular religion, or any religion at all. For all anyone knows, the supposed Intelligent Designers might be an alien species of mortal, ungodlike beings.

To the Darwinists, of course, this is hypocrisy and deception -- of course the Designists are religious. They must be. Because only religious people would ever question the Darwinist model.

It comes to this: If you question the Darwinist model, you must be religious; therefore your side of the argument is not admissible in the public arena, and certainly not in the public schools.

This is an attempt to shut down discussion by hiding behind the Constitution. It's what you do when you're pretty sure you can't win on the merits.

6. The "we can't possibly find every step along the way" argument is an old one that doesn't actually fit the current situation. It is the correct answer when defending the idea of evolution against those who believe in an ex nihilo creation in six days.

The fossil record is very clear in showing the divergence of species, with old ones going extinct and new ones arising over a long period of time. And the general progression is from simpler to more-complex organisms. The fact that evolution takes place is obvious. You don't have to find some improbable fossil graveyard where each generation conveniently lay down next to their parents' bodies when it came time to die.

But fossils only show physical structures, and the Intelligent Design argument concedes the point. The Designists (or at least the smart ones) are not arguing for biblical literalism. They freely admit that evolution obviously takes place, that simple organisms were followed by more complex ones.

They also accept the other obvious arguments for evolution, like the similarity of genes among different species. They have no problem with the idea that chimps are so genetically similar to us because we share a common ancestor.

Their argument isn't against evolution per se. Nor are they doubting that natural selection takes place. Their argument is that the Darwinian model is not a sufficient explanation.

So "we can't find fossils representing every step of evolution" has nothing to do with the issues being raised. The Designists are not anti-evolution. They are anti-Darwin.

Darwinism vs. Evolution

Here's the place where a lot of scientists indulge in muddy thinking. Evolution and Darwinism have been treated as synonyms for so long that too many people think they're the same thing. But they're not, and never have been.

Darwin did not think up the idea of evolution any more than Columbus proved to a bunch of flat-earthers that the world was round.

In fact, the Columbus analogy is an apt one. Columbus was actually wrong -- he was arguing, not that the Earth was round (everybody knew that already) but that the Earth was much smaller than it really is. His claim was that the Earth was so small that if you sailed west from Spain, you'd find Japan at about the point where in fact you find Cuba.

He was vastly, ridiculously wrong -- but because his expedition got funded, he was able to sail west far enough to bump into a largely unknown (to Europe) land mass, and the civilizations that dwelt on it.

Whereas the sensible people who knew how big the Earth was refused to endanger themselves by sailing west on a voyage so long that no ship could carry enough supplies. And therefore discovered nothing.

Darwin's contribution to biological science is enormous. He posited a means by which science could study the passage of organisms from one species to another over time. Before Darwin (and the others who were working in the same direction), there were many who believed in evolution, but accounted it part of the "great chain of being" ordained by God.

Here's the thing: If you say that things are as they are because God made them that way, then they are off limits to science. Science is simply unsuited to studying God. Science requires impersonal, repeatable testing. Its business is discovering causal relationships, and it can only work with mechanical cause.

So when the answer to the question "why does this natural phenomenon occur?" is "because God wants it that way," then science simply has nothing to add to the conversation. Any more than when the question is "why are you wearing that combination of colors?" If some person -- divine or otherwise -- chose to make things as they are, then we're talking about purpose and motive; science can only work with mechanical causation.

In other words, until Darwin showed us evolution as a machine that did not require divine meddling to be explained, scientists were blocked from answering what seemed to be (and, in some ways, is) a mere historical, not scientific, question: How did this vast variety of life forms come to be?

The Scientific Method

Of course scientists can't document every step of the historical process of evolution. That wouldn't be science anyway, it would be mere data collection.

What science does is to invent plausible stories of automatic processes by which natural events, systems, and objects come to be as we see them.

Then the story is tested, either by experiments designed to prove the story false, or by making predictions about what else must exist if the story is true, and then seeing if the predictions are right.

Science examines ongoing processes that proceed from mechanical causes; Darwin, by convincingly describing evolution as such a process, opened the door to millions of insights into the workings of organisms of every size.

Make no mistake: Not just the fossil record, but virtually every close examination of biology at every level reveals utterly convincing evidence that evolution takes place, has always taken place, and continues to take place. There is also plenty of evidence that natural selection takes place.

The Designists challenge only the sufficiency of Darwin's model. The claim only that it does not seem adequate to explain systems that were completely unknown at the time he created his theory.

Insufficiencies

Darwin himself knew that there were sticky places where his theory wasn't a sufficient explanation. He wrestled with the problem of altruism, for instance, and while he found adequate natural-selection explanations for some forms of altruism (for instance, the mother bird that draws off predators, potentially sacrificing her life, to promote the survival of her offspring), there were other behaviors that were inexplicable by means of natural selection (for instance, humans who voluntarily go to war to protect strangers).

There are other problems with Darwin's model. For instance, the idea of gradual change at a consistent rate is challenged in some respects by the fossil record. Some organisms have persisted virtually unchanged for millions of years, only to suddenly disappear; others have seemed to spring up suddenly, with few or seemingly no precursors.

The result was a modification in doctrinaire Darwinism, called the "punctuational model," which proposed that evolution can happen in bursts that are much more rapid than the normal pace. It is not really so much a contradiction of Darwinism as an elaboration of it, a revision to help it fit observed reality better.

Why Theories Get Revised

It is vital to keep in mind that Darwin's theory is a theory, not in the way that Creationists mean (i.e., a theory and therefore not a fact), but in the way that scientists use the word "theory": a story that accounts for all the data that we've found so far.

But good science always examines its theories and compares them to the evidence, to see if they are still adequate. That's how Newton's "laws" (i.e., theoretical constants) were able to be superseded by Einstein's -- not because they weren't true, but because they couldn't adequately explain all the phenomena that were being observed.

I specify "good science" because if, at any point, any theory becomes a dogma that no one is allowed to question, it stops being good science. Indeed, it stops being science at all, and becomes its opposite -- its enemy.

Darwin himself was a scientist, and a great one, in part because he was constantly probing and questioning his own ideas.

But an astonishing number of his defenders today are, at least when discussing Darwinism, not scientists at all.

They instead behave like religious fanatics whose favorite dogmas are being challenged. That's why they answer their serious critics with name-calling, credentialism, expertism, sniping, politics, and misdirection, answering questions that have not been asked, using answers that have nothing to do with the real questions.

They have no good answers, and yet they have an unshakable faith in Darwinism; so they fervently and vehemently attack their attackers, waging, not one side in a scientific conversation, but a crusade against those who do not treat their Prophet with enough respect.

More respect, in fact, than Darwin would have wanted or ever showed for his own ideas. Darwin had no problem with questioning Darwinism. He constantly entertained the possibility that he was wrong about this, that, or everything. Would that his disciples today would adopt the same attitude.

Here's the only correct answer to the Designists:

7. Yes, there are problems with the Darwinian model. But those problems are questions. "Intelligent design" is an answer, and you have no evidence at all for that.

A Religious Squabble

Intelligent design uses the evil "must" word: Well, if random mutation plus natural selection can't account for the existence of this complex system, then it must have been brought into existence by some intelligent designer

Why? Why must that be the only alternative?

Just because the Darwinian model seems to be inadequate at the molecular level does not imply in any way that the only other explanation is purposive causation.

There might be several or even many other hypotheses. To believe in Intelligent Design is still a leap of faith.

But the normal answer of the Darwinists is also a leap of faith. In effect, their arguments boil down to this: We have no idea right now how these complex systems came to be, but we have fervent, absolute faith that when we do figure it out, it will be found to have a completely mechanical, natural cause that requires no "intelligent designer" at all.

If the Darwinists' faith is eventually proved correct, and we find completely natural, mechanical explanations for the evolution of complex biochemical systems, then these matters will remain within the purview of the scientific method. They will still be teachable in science class.

But if the Designists are right, and there is no natural explanation, no process of mechanical causation that can possibly lead to the automatic evolution of complex biochemical systems, then at that moment the subject ceases to be science at all, and becomes either history (what did the Designers do and why did they do it?) or theology (what does God mean by all this?).

That's fine. There are lots of subjects in this world that are worth studying, and in which true and valuable things can be discovered, which are not and cannot be science.

But when you purport to teach science in school, the subject you teach had better be science, and not somebody's religion in disguise.

That's the problem with both sides in this squabble. They are both functioning as religions, and they should stop it at once.

If both sides would behave like scientists, there wouldn't even be a controversy, because everyone would agree on this statement:

Evolution happens and obviously happened in the natural world, and natural selection plays a role in it. But we do not have adequate theories yet to explain completely how evolution works and worked at the biochemical level.

That is a true statement, according to our present state of scientific knowledge.

And when Darwinists scream that we do too know how to explain evolution, and it's natural selection, so just stop talking about it, they are dogmatists demanding that their faith -- the faith that Darwin's model will be found to explain everything when we just understand things better -- be taught in the public schools.

There is no reason for science teachers in the public schools to take a single step beyond that statement I made above. It allows the teaching of every speck of scientific biology; and it makes moot the as-yet-unknowable issue of how each specific complex biochemical system came into existence.

In fact, what every school board in this country should decide is to ignore both sides' demands that the schools teach their faith, and allow the public schools to perform their public service: educating children in our shared culture, including what we have learned through the scientific method.

Real science does not in any way impinge on a belief that God (or some other Intelligent Designer) created the world and everything that dwells in it. At the same time, real science does not -- and never can -- prove or even support the hypothesis.

But real science also does not support a misguided faith in the teachings of a scientist who is now regarded as a prophet, and whose disciples have an emotional commitment to his theories, even when they can be shown to be inadequate to explain the data as we presently have it.

Physicists know this -- they don't get their dander up and demand that non-Einsteinian physics never be taught in the public schools, for instance. They recognize that at the bleeding edge of science we simply don't know stuff yet, and no past genius has authority today, if and when we come up with data that may not support his theories.

Biology is no different. Darwin gave us a huge leap forward. But he did not take us all the way to final truth -- no scientist ever can or ever will, by the definition of what science is and scientists do.

When somebody -- anybody -- asks hard questions of a theory, then the scientific answer is never "shut up and go away." The scientific answer is, "Let's see if we can find out."

Meanwhile ... what do I believe about the origin of life? I believe that God created it, employing and obeying natural laws, but at levels beyond our understanding. I believe we're here on this earth for God's beneficent purposes.

But I have no interest whatsoever in having schoolteachers train my or anyone else's children in any religion. My wife and I teach our beliefs to our children and help them put what they learn at school in perspective. We encourage them to question everything -- including what we teach them -- but we expect them to adhere to rigorous standards in deciding what they should believe.

I don't have to call upon religious faith to contradict the claims of bad science. I'll reserve it to deal with the claims of bad religion. An understanding of good science is always enough to sweep away the overclaiming of those "scientists" who, as the religious fanatics they are, wish to impose their faith on everyone.
