The "Threat" of Creationism, by Isaac Asimov

Scientists thought it was settled. The universe, they had decided, is about 20 billion years old, and Earth itself is 4.5 billion years old. Simple forms of life came into being more than three billion years ago, having formed spontaneously from nonliving matter. They grew more complex through slow evolutionary processes and the first hominid ancestors of humanity appeared more than four million years ago. Homo sapians itself—the present human species, people like you and me—has walked the earth for at least 50,000 years.

But apparently it isn't settled. There are Americans who believe that the earth is only about 6,000 years old; that human beings and all other species were brought into existence by a divine Creator as eternally separate variations of beings; and that there has been no evolutionary process.

They are creationists—they call themselves "scientific" creationists—and they are a growing power in the land, demanding that schools be forced to teach their views. State legislatures, mindful of the votes, are beginning to succumb to the pressure. In perhaps 15 states, bills have been introduced, putting forth the creationist point of view, and in others, strong movements are gaining momentum. In Arkansas, a law requiring that the teaching of creationism receive equal time was passed this spring and is scheduled to go into effect in September 1982, though the American Civil Liberties Union has filed suit on behalf of a group of clergymen, teachers, and parents to overturn it. And a California father named Kelly Segraves, the director of the Creation-Science Research Center, sued to have public-school science classes taught that there are other theories of creation besides evolution, and that one of them was the Biblical version. The suit came to trial in March, and the judge ruled that educators must distribute a policy statement to schools and textbook publishers explaining that the theory of evolution should not be seen as "the ultimate cause of origins." Even in New York, the Board of Education has delayed since January in making a final decision, expected this month [June 1981], on whether schools will be required to include the teaching of creationism in their curriculums.

The Rev. Jerry Fallwell, the head of the Moral Majority, who supports the creationist view from his television pulpit, claims that he has 17 million to 25 million viewers (though Arbitron places the figure at a much more modest 1.6 million). But there are 66 electronic ministries which have a total audience of about 20 million. And in parts of the country where the Fundamentalists predominate—the so called Bible Belt— creationists are in the majority.

They make up a fervid and dedicated group, convinced beyond argument of both their rightness and their righteousness. Faced with an apathetic and falsely secure majority, smaller groups have used intense pressure and forceful campaigning—as the creationists do—and have succeeded in disrupting and taking over whole societies.

Yet, though creationists seem to accept the literal truth of the Biblical story of creation, this does not mean that all religious people are creationists. There are millions of Catholics, Protestants, and Jews who think of the Bible as a source of spiritual truth and accept much of it as symbolically rather than literally true. They do not consider the Bible to be a textbook of science, even in intent, and have no problem teaching evolution in their secular institutions.

To those who are trained in science, creationism seems like a bad dream, a sudden reveling of a nightmare, a renewed march of an army of the night risen to challenge free thought and enlightenment.

The scientific evidence for the age of the earth and for the evolutionary development of life seems overwhelming to scientists. How can anyone question it? What are the arguments the creationists use? What is the "science" that makes their views "scientific"? Here are some of them:

A watch implies a watchmaker, say the creationists. If you were to find a beautifully intricate watch in the desert, from habitation, you would be sure that it had been fashioned by human hands and somehow left it there. It would pass the bounds of credibility that it had simply formed, spontaneously, from the sands of the desert.

By analogy, then, if you consider humanity, life, Earth, and the universe, all infinitely more intricate than a watch, you can believe far less easily that it "just happened." It, too, like the watch, must have been fashioned, but by more-than-human hands—in short by a divine Creator.

This argument seems unanswerable, and it has been used (even though not often explicitly expressed) ever since the dawn of consciousness. To have explained to prescientific human beings that the wind and the rain and the sun follow the laws of nature and do so blindly and without a guiding would have been utterly unconvincing to them. In fact, it might have well gotten you stoned to death as a blasphemer.

There are many aspects of the universe that still cannot be explained satisfactorily by science; but ignorance only implies ignorance that may someday be conquered. To surrender to ignorance and call it God has always been premature, and it remains premature today.

In short, the complexity of the universe—and one's inability to explain it in full—is not in itself an argument for a Creator.

Some creationists point at that belief in a Creator is general among all peoples and all cultures. Surly this unanimous craving hints at a greater truth. There would be no unanimous belief in a lie.

General belief, however, is not really surprising. Nearly every people on earth that considers the existence of the world assumes it to have been created by a god or gods. And each group invents full details for the story. No two creation tales are alike. The Greeks, the Norsemen, the Japanese, the Hindus, the American Indians, and so on and so on all have their own creation myths, and all of these are recognized by Americans of Judeo-Christian heritage as "just myths."

The ancient Hebrews also had a creation tale—two of them, in fact. There is a primitive Adam-and-Eve-in-Paradise story, with man created first, then animals, then women. There is also a poetic tale of God fashioning the universe in six days, with animals preceding man, and man and woman created together.

These Hebrew myths are not inherently more credible than any of the others, but they are our myths. General consent, of course, proves nothing: There can be a unanimous belief in something that isn't so. The universal opinion over thousands of years that the earth was flat never flattened its spherical shape by one inch.

Creationists frequently stress the fact that evolution is "only a theory," giving the impression that a theory is an idle guess. A scientist, one gathers, arising one morning with nothing particular to do, decided that perhaps the moon is made of Roquefort cheese and instantly advances the Roquefort-cheese theory.

A theory (as the word is used by scientists) is a detailed description of some facet of the universe's workings that is based on long observation and, where possible, experiment. It is the result of careful reasoning from these observations and experiments that has survived the critical study of scientists generally.

For example, we have the description of the cellular nature of living organisms (the "cell theory"); of objects attracting each other according to fixed rule (the "theory of gravitation"); of energy behaving in discrete bits (the "quantum theory"); of light traveling through a vacuum at a fixed measurable velocity (the "theory of relativity"), and so on.

All are theories; all are firmly founded; all are accepted as valid descriptions of this or that aspect of the universe. They are neither guesses nor speculations. And no theory is better founded, more closely examined, more critically argued and more thoroughly accepted, than the theory of evolution. If it is "only" a theory, that is all it has to be.

Creationism, on the other hand, is not a theory. There is no evidence, in the scientific sense, that supports it. Creationism, or at least the particular variety accepted by many Americans, is an expression of early Middle Eastern legend. It is fairly described as "only a myth."

Creationists, in recent years, have stressed the "scientific" background of their beliefs. They point out that there are scientists who base their creationists beliefs on a careful study of geology, paleontology, and biology and produce "textbooks" that embody those beliefs.

Virtually the whole scientific corpus of creationism, however, consists of the pointing out of imperfections in the evolutionary view. The creationists insists, for example, that evolutionists cannot true transition states between species in the fossil evidence; that age determinations through radioactive breakdown are uncertain; that alternative interpretations of this or that piece of evidence are possible and so on.

Because the evolutionary view is not perfect and is not agreed upon by all scientists, creationists argue that evolution is false and that scientists, in supporting evolution, are basing their views on blind faith and dogmatism.

To an extent, the creationists are right here: The details of evolution are not perfectly known. Scientists have been adjusting and modifying Charles Darwin's suggestions since he advanced his theory of the origin of species through natural selection back in 1859. After all, much has been learned about the fossil record and physiology, microbiology, biochemistry, ethology, and various other branches of life science in the last 125 years, and it was to be expected that we can improve on Darwin. In fact, we have improved on him. Nor is the process finished. it can never be, as long as human beings continue to question and to strive for better answers.

The details of evolutionary theory are in dispute precisely because scientists are not devotees of blind faith and dogmatism. They do not accept even as great thinker as Darwin without question, nor do they accept any idea, new or old, without thorough argument. Even after accepting an idea, they stand ready to overrule it, if appropriate new evidence arrives. If, however, we grant that a theory is imperfect and details remain in dispute, does that disprove the theory as a whole?

Consider. I drive a car, and you drive a car. I do not know exactly how an engine works. Perhaps you do not either. And it may be that our hazy and approximate ideas of the workings of an automobile are in conflict. Must we then conclude from this disagreement that an automobile does not run, or that it does not exist? Or, if our senses force us to conclude that an automobile does exist and run, does that mean it is pulled by an invisible horses, since our engine theory is imperfect?

However much scientists argue their differing beliefs in details of evolutionary theory, or in the interpretation of the necessarily imperfect fossil record, they firmly accept the evolutionary process itself.

Creationists have learned enough scientific terminology to use it in their attempts to disprove evolution. They do this in numerous ways, but the most common example, at least in the mail I receive is the repeated assertion that the second law of thermodynamics demonstrates the evolutionary process to be impossible.

In kindergarten terms, the second law of thermodynamics says that all spontaneous change is in the direction of increasing disorder—that is, in a "downhill" direction. There can be no spontaneous buildup of the complex from the simple, therefore, because that would be moving "uphill." According to the creationists argument, since, by the evolutionary process, complex forms of life evolve from simple forms, that process defies the second law, so creationism must be true.

Such an argument implies that this clearly visible fallacy is somehow invisible to scientists, who must therefore be flying in the face of the second law through sheer perversity. Scientists, however, do know about the second law and they are not blind. It's just that an argument based on kindergarten terms is suitable only for kindergartens.

To lift the argument a notch above the kindergarten level, the second law of thermodynamics applies to a "closed system"—that is, to a system that does not gain energy from without, or lose energy to the outside. The only truly closed system we know of is the universe as a whole.

Within a closed system, there are subsystems that can gain complexity spontaneously, provided there is a greater loss of complexity in another interlocking subsystem. The overall change then is a complexity loss in a line with the dictates of the second law.

Evolution can proceed and build up the complex from the simple, thus moving uphill, without violating the second law, as long as another interlocking part of the system — the sun, which delivers energy to the earth continually — moves downhill (as it does) at a much faster rate than evolution moves uphill. If the sun were to cease shining, evolution would stop and so, eventually, would life.

Unfortunately, the second law is a subtle concept which most people are not accustomed to dealing with, and it is not easy to see the fallacy in the creationists distortion.

There are many other "scientific" arguments used by creationists, some taking quite cleaver advantage of present areas of dispute in evolutionary theory, but every one of then is as disingenuous as the second-law argument.

The "scientific" arguments are organized into special creationist textbooks, which have all the surface appearance of the real thing, and which school systems are being heavily pressured to accept. They are written by people who have not made any mark as scientists, and, while they discuss geology, paleontology and biology with correct scientific terminology, they are devoted almost entirely to raising doubts over the legitimacy of the evidence and reasoning underlying evolutionary thinking on the assumption that this leaves creationism as the only possible alternative.

Evidence actually in favor of creationism is not presented, of course, because none exist other than the word of the Bible, which it is current creationist strategy not to use.

Some creationists putt all matters of scientific evidence to one side and consider all such things irrelevant. The Creator, they say, brought life and the earth and the entire universe into being 6,000 years ago or so, complete with all the evidence for eons-long evolutionary development. The fossil record, the decaying radio activity, the receding galaxies were all created as they are, and the evidence they present is an illusion.

Of course, this argument is itself irrelevant, for it can be neither proved nor disproved. it is not an argument, actually, but a statement. I can say that the entire universe was created two minutes age, complete with all its history books describing a nonexistent past in detail, and with every living person equipped with a full memory; you, for instance, in the process of reading this article in midstream with a memory of what you had read in the beginning—which you had not really read.

What kind of Creator would produce a universe containing so intricate an illusion? It would mean that the Creator formed a universe that contained human beings whom He had endowed with the faculty of curiosity and the ability to reason. He supplied those human beings with an enormous amount of subtle and cleverly consistent evidence designed to mislead them and cause them to be convinced that the universe was created 20 billion years ago and developed by evolutionary processes that include the creation and the development of life on Earth. Why?

Does the Creator take pleasure in fooling us? Does it amuse Him to watch us go wrong? Is it part of a test to see if human beings will deny their senses and their reason in order to cling to myth? Can it be that the Creator is a cruel and malicious prankster, with a vicious and adolescent sense of humor?

The Bible says that God created the world in six days, and the Bible is the inspired word of God. To the average creationist this is all that counts. All other arguments are merely a tedious way of countering the propaganda of all those wicked humanists, agnostics, an atheists who are not satisfied with the clear word of the Lord.

The creationist leaders do not actually use that argument because that would make their argument a religious one, and they would not be able to use it in fighting a secular school system. They have to borrow the clothing of science, no matter how badly it fits, and call themselves "scientific" creationists. They also speak only of the "Creator," and never mentioned that this Creator is the God of the Bible.

We cannot, however, take this sheep's clothing seriously. However much the creationist leaders might hammer away at in their "scientific" and "philosophical" points, they would be helpless and a laughing-stock if that were all they had.

It is religion that recruits their squadrons. Tens of millions of Americans, who neither know nor understand the actual arguments for or even against evolution, march in the army of the night with their Bibles held high. And they are a strong and frightening force, impervious to, and immunized against, the feeble lance of mere reason.

Even if I am right and the evolutionists' case is very strong, have not creationists, whatever the emptiness of their case, a right to be heard? if their case is empty, isn't it perfectly safe to discuss it since the emptiness would then be apparent? Why, then are evolutionists so reluctant to have creationism taught in the public schools on an equal basis with evolutionary theory? can it be that the evolutionists are not as confident of their case as they pretend. Are they afraid to allow youngsters a clear choice?

First, the creationists are somewhat less than honest in their demand for equal time. It is not their views that are repressed: schools are by no means the only place in which the dispute between creationism and evolutionary theory is played out. There are churches, for instance, which are a much more serious influence on most Americans than the schools are. To be sure, many churches are quite liberal, have made their peace with science and find it easy to live with scientific advance — even with evolution. But many of the less modish and citified churches are bastions of creationism.

The influence of the church is naturally felt in the home, in the newspapers, and in all of surrounding society. It makes itself felt in the nation as a whole, even in religiously liberal areas, in thousands of subtle ways: in the nature of holiday observance, in expressions of patriotic fervor, even in total irrelevancies. In 1968, for example, a team of astronomers circling the moon were instructed to read the first few verses of Genesis as though NASA felt it had to placate the public lest they rage against the violation of the firmament. At the present time, even the current President of the United States has expressed his creationist sympathies.

It is only in school that American youngsters in general are ever likely to hear any reasoned exposition of the evolutionary viewpiont. They might find such a viewpoint in books, magazines, newspapers, or even, on occasion, on television. But church and family can easily censor printed matter or television. Only the school is beyond their control.

But only just barely beyond. Even though schools are now allowed to teach evolution, teachers are beginning to be apologetic about it, knowing full well their jobs are at the mercy of school boards upon which creationists are a stronger and stronger influence.

Then, too, in schools, students are not required to believe what they learn about evolution—merely to parrot it back on test. If they fail to do so, their punishment is nothing more than the loss of a few points on a test or two.

In the creationist churches, however, the congregation is required to believe. Impressionable youngsters, taught that they will go to hell if they listen to the evolutionary doctrine, are not likely to listen in comfort or to believe if they do. Therefore, creationists, who control the church and the society they live in and to face the public-school as the only place where evolution is even briefly mentioned in a possible favorable way, find they cannot stand even so minuscule a competition and demand "equal time."

Do you suppose their devotion to "fairness" is such that they will give equal time to evolution in their churches?

Second, the real danger is the manner in which creationists want threir "equal time." In the scientific world, there is free and open competition of ideas, and even a scientist whose suggestions are not accepted is nevertheless free to continue to argue his case. In this free and open competition of ideas, creationism has clearly lost. It has been losing, in fact, since the time of Copernicus four and a half centuries ago. But creationism, placing myth above reason, refused to accept the decision and are now calling on the government to force their views on the schools in lieu of the free expression of ideas. Teachers must be forced to present creationism as though it had equal intellectual respectability with evolutionary doctrine.

If the government can mobilize its policemen and its prisons to make certain that teachers give creationism equal time, they can next use force to make sure that teachers declare creationism the victor so that evolution will be evicted from the classroom altogether. We will have established ground work, in other words, for legally enforced ignorance and for totalitarian thought control. And what if the creationists win? They might, you know, for there are millions who, faced with a choice between science and their interpretation of the Bible, will choose the Bible and reject science, regardless of the evidence.

This is not entirely because of the traditional and unthinking reverence for the literal words of the Bible; there is also a pervasive uneasiness—even an actual fear—of science that will drive even those who care little for fundamentalism into the arms of the creationists. For one thing, science is uncertain. Theories are subject to revision; observations are open to a variety of interpretations, and scientists quarrel among themselves. This is disillusioning for those untrained in the scientific method, who thus turn to the rigid certainty of the Bible instead. There is something comfortable about a view that allows for no deviation and that spares you the painful necessity of having to think.

Second, science is complex and chilling. The mathematical language of science is understood by very few. The vistas it presents are scary—an enormous universe ruled by chance and impersonal rules, empty and uncaring, ungraspable and vertiginous. How comfortable to turn instead to a small world, only a few thousand years old, and under God's personal and immediate care; a world in which you are his particular concern and where He will not consign you to hell if you are careful to follow every word of the Bible as interpreted for you by your television preacher.

Third, science is dangerous. There is no question but that poison gas, genetic engineering, and nuclear weapons and power stations are terrifying. It may be that civilization is falling apart and the world we know is coming to an end. In that case, why not turn to religion and look forward to the Day of Judgment, in which you and your fellow believers will be lifted into eternal bliss and have the added joy of watching the scoffers and disbelievers writhe forever in torment.

There are numerous cases of societies in which the armies of the night have ridden triumphantly over minorities in order to establish a powerful orthodoxy which dictates official thought. Invariably, the triumphant ride is toward long-range disaster. Spain dominated Europe and the world in the 16th century, but in Spain orthodoxy came first, and all divergence of opinion was ruthlessly suppressed. The result was that Spain settled back into blankness and did not share in the scientific, technological and commercial ferment that bubbled up in other nations of Western Europe. Spain remained an intellectual backwater for centuries. In the late 17th century, France in the name of orthodoxy revoked the Edict of Nantes and drove out many thousands of Huguenots, who added their intellectual vigor to lands of refuge such as Great Britain, the Netherlands, and Prussia, while France was permanently weakened.

In more recent times, Germany hounded out the Jewish scientists of Europe. They arrived in the United States and contributed immeasurably to scientific advancement here, while Germany lost so heavily that there is no telling how long it will take it to regain its former scientific eminence. The Soviet Union, in its fascination with Lysenko, destroyed its geneticists, and set back its biological sciences for decades. China, during the Cultural Revolution, turned against Western science and is still laboring to overcome the devastation that resulted.

As we now, with all these examples before us, to ride backward into the past under the same tattered banner of orthodoxy? With creationism in the saddle, American science will wither. We will raise a generation of ignoramuses ill-equipped to run the industry of tomorrow, much less to generate the new advances of the days after tomorrow.

We will inevitably recede into the backwater of civilization, and those nations that retain opened scientific thought will take over the leadership of the world and the cutting edge of human advancement. I don't suppose that the creationists really plan the decline of the United States, but their loudly expressed patriotism is as simpleminded as their "science." If they succeed, they will, in their folly, achieve the opposite of what they say they wish.

Kolmogorov did some very important foundational work, primarily in that he fixed one of the key deficiencies in Shannon's work. That said, while the foundations he laid are as valid as they ever were, the field has advanced substantially beyond where he left it. Algorithmic Information Theory, which is essentially the proper descendent of Kolmogorov's mathematics, has started to yield some very important developments regarding computational information theory in general. One could very much argue that it is the most important direction currently being explored in computer theory, and is solving some long outstanding questions in the field. In theoretical computer science, this is one of the areas that is really starting to get hot. It is increasingly clear that it is far more important than a lot of people initially thought it was. Such is the history of discovery.

AIT is essentially my area of expertise in mathematics, particularly as it applies to computational theory. My particular sub-specialty is this field of mathematics as applied to finite systems. Virtually all mathematics dealing with computational theory does NOT assume finite systems, which is a bit odd since all practical computers ARE finite systems.

Hmmm... but the DNA system has both digital and analog components. (Ex.: the genes' sequences and the amounts which they get expressed.) Can analog components be part of Turing machines too?

Arrrgh... There is no mathematical distinction between "analog" and "digital" systems. These are information encoding formats i.e. an artifact of human engineering, not fundamental truths of some sort. Therefore, they can be treated the same. The only conditions under which analog systems are mathematically different than digital systems are when you have no noise floor (i.e. infinite SNR) -- not in THIS universe. And in the same universe, you could have infinite-bit digital encoding anyway, so it would be a wash. This analog-versus-digital false dichotomy is one of those Myths That Won't Die, and it drives me mad.

As a result, yes, analog encoded information can be part of a Turing machine without any consequences.

The rough rule of thumb for converting the dynamic range of an analog signal into the equivalent number of required digital bits for information theoretical purposes, is that you take the dynamic range of the analog signal and divide it by 6. There is a proper mathematical conversion, but this gets you close enough for government work. In living organisms, the effective dynamic range of the system probably isn't more than 40-60dB, which gives you a whopping 10 bits of information tops. An actual mathematical analysis is substantially more complicated than this, but you get the idea. 6-10 bits is pretty sad; the complexity is that there are a LOT of components in the system with this much information content and it adds up damn quick.

Once again you didn't address my point. For example, look at DeathFromBelow's posts on this very thread.

The problem is you are too busy looking and studying the wrong things.

What is his solution to the "evil" science of the theory of evolution - STOP STUDYING IT. Don't try to prove it wrong, don't replace it with something better, just make it go away. Oh, please, Mr. Scientist, make it go away!!!

Now, is his attitude any different than Anti-Pope GoreMMM's? Or Phaedrus's I'm-always-right-so-shut-up-and-go-away style? Or f.Christian's bizarre babbling and non-sequitur cut-and-paste reposts? Or any of the post-some-scripture-and-then-run-away Freepers that pop in from time to time? As, Patrick Henry pointed out, these "Creationists" are the rule not the exception.

Creationists don't need to prove evolution wrong. It is evolution-from-nothing believers who seem to need to prove God wrong, or at least illegal.

"If I could figure out what you're trying to say, and how it relates to the theory of evolution, I would respond."

I'm trying to say creationism is not a threat to science. If it were, then we should not be sending those who adhere to creationist ideas into outer space lest they be tempted to dilute "pure" science on account of their creationist predilections.

Asimov:

"With creationism in the saddle, American science will wither. We will raise a generation of ignoramuses ill-equipped to run the industry of tomorrow, much less to generate the new advances of the days after tomorrow."

That's not only a joke, but a downright thankless insult to those creationists upon whose shoulder's the better number of scientists stand.

Creationists don't need to prove evolution wrong.

Tell that to the other Creationists.

It is evolution-from-nothing believers who seem to need to prove God wrong, or at least illegal.

I'm not sure what you're trying to say here. Certainly there are evolutionists here who believe in (various versions of) God and nobody is trying to make them change their minds.

I'm not sure what you're trying to say here. Certainly there are evolutionists here who believe in (various versions of) God and nobody is trying to make them change their minds.

Is that Mr. Asimov's and Mr. Patrick (incongruous monicker) Henry's position, by their statements? They seem to be part and parcel with those who would ban the conveyance of Creationism education from public schools, which is to say "only spontaneous life generation theories allowed, in our science class." (Hardly a matter for science.)

Am I wrong in that impression?

I hate to do this as it may help the creationists a bit at least it will make their argument more specific.

But not one of you know how DNA functions. You may know computers but you don't know DNA. DNA has no function other than a store house of information. DNA does nothing else. RNA and MRNA do all the work. RNA travels along the DNA reading the code it then copies a section which is taken to the ribosome. In the ribosome the copied section of DNA is processed three bases at a time this is called the base triplet. Transfer RNA picks up these base triplets these transfer RNA string out into clusters called proteins These proteins tell the body how to grow. (Color of eyes, height, etc).

DNA by itself is a template nothing else it does nothing else. RNA is not DNA, neither is MRNA, and neither are proteins. I have stated all along that you cannot look at DNA as a separate entity it is a small part of a system a very large system. It is merely a store house of information or may I say again a template. It is not a processor. The cell itself may be seen as a processor but DNA does not process information.

If you want to argue if other parts of a cell are processors that is a differnet argument and I will use different tactics but DNA is not a processor or a computer or a turing machine. If DNA is a Turning machine instructions for putting together a stereo is a turing machine. IF stereo instructions count as a turing machine then I am mistaken about what a Turing machine is.

DNA does process instruction sets and data, and it is BECAUSE DNA is processing, rather than merely repeating as would a blind template, that DNA knows to ignore an entire gene when we place a genetic marker (in this case the computer programming equivilent of EXIT SUB) at the beginning of the gene's data.

This, I'm afraid, is nonsense. The information in DNA is replicated by a system of enzymes centered around DNA polymerases, and transcribed to RNA by another system of enzymes interacting with the RNA polymerases. DNA does not transcribe itself. It contains start and stop signals for transcription, but these are read by enzymes, not by DNA.

You appear to think DNA is a Turing machine. It isn't.

"This, I'm afraid, is nonsense.

You've managed to read my shorthand in some posts (my fault, sorry) and draw a useless conclusion (e.g. that DNA doesn't process data/commands and that DNA isn't a Turing machine).

However, if you are actually intellectually honest (and at this point, I have no reason to doubt that fact) and you read ALL of my posts on this thread, you will see that what I am actually saying (when I'm not being lazy-enough to use shorthand) is that the DNA system (not simply DNA per se) is doing the processing of the data/commands stored in DNA.

And once you understand that I am referring to the entire cell, then you can draw an accurate conclusion (rather than the useless one that you referred to above); namely that the DNA system does indeed process data and commands, and that this DNA system is indeed a Turing Machine.

"If you want to argue if other parts of a cell are processors that is a differnet argument and I will use different tactics but DNA is not a processor or a computer or a turing machine. If DNA is a Turning machine instructions for putting together a stereo is a turing machine. IF stereo instructions count as a turing machine then I am mistaken about what a Turing machine is."

What's this?! Dare I believe my own eyes??

Is Sentis finally admitting that DNA contains ... dramatic pause ... PROGRAMMING INSTRUCTIONS?!

Good Lord, we have ourselves an Intellectual Breakthrough by one of our Darwinists!

Why at this rate, you'll soon be comprehending that we've been discussing the DNA system, not simply DNA per se, all along.

And good grief, once you reach that conclusion, the sky is the limit for you!

You might even "get" what we've been saying, and why, all along!

(well, I can dream, can't I)

Thanks for the clarification.

The cell isn't a Turing machine either, in that there is no 'write' function. If you regard DNA as the tape; it's read, but it's certainly not written. The essence of a Turing machine, as I understand it, is that bits are read and written sequentially. The cell reads many DNA sequences in parallel.

That being said, DNA is my area of expertise, not computer science; I look a grad. course in machines languages and computation 20 years ago, but since then my knowledge of the subject is at a Sci. Am. level.

Is that Mr. Asimov's and Mr. Patrick (incongruous monicker) Henry's position, by their statements?

Ask them. But be specific.

They seem to be part and parcel with those who would ban the conveyance of Creationism education from public schools,

So am I. It's not science and doesn't belong in a science class.

... which is to say "only spontaneous life generation theories allowed, in our science class." (Hardly a matter for science.)

While it is NOT part of the Theory of Evolution, it is a current scientific hypothesis and research is being done on it. Have you got a alternative scientific hypothesis to propose?

Cell Replication

One cell divides into two daughter cells

Homologous chromosomes: one from mother, one from father. Humans have 23 of these pairs of chromosomes (46 total chromosomes).
