DNA: good discovery, bad agenda

What a difference 65 years makes. It was in April of 1953 that a one-page letter appeared in the journal Nature. Two young scientists believed that they had figured out the double helical structure of deoxyribonucleic acid or DNA. In their communication to the journal, these men remarked with masterful understatement that, “This structure has novel features which are of considerable biological interest.” This was indeed the case.

What these two men had achieved was to explain how the long DNA molecule in chromosomes stores information which can be accurately duplicated. This discovery has led directly to DNA fingerprinting, biotechnology, the sequencing of the human genome and evolutionary theories based on DNA sequences in various organisms. Although 65 years ago it was much too soon to foresee all these developments, nevertheless informed individuals understood that a significant milestone had been achieved.

NOBODIES ARE SOMEBODY TOO

The big surprise in 1953 was not that the structure, and by implication the function, of DNA had been discovered, but rather who had done it. With established scientists like American Linus Pauling of Caltech in Pasadena, and British scientists Maurice Wilkins and Rosalind Franklin at King’s College, University of London, carrying out such research, it was expected that the problem would soon be solved. These scientists all had research funds, equipment and established names in science.

On the other hand, the British Francis Crick (1916-2004) and American James Watson (b. 1928) were basically nobodies in the scientific community. Crick for his part, his career having been interrupted by war service, was still a graduate student in 1953. Four years earlier, he had come to the Cambridge Medical Research Council Unit. His base of operations was the Cavendish physics lab where Nobel laureate Ernest Rutherford had achieved great things in the 1930s. Crick might be merely a graduate student, but he was nevertheless skilled in the methods of X-ray diffraction, so useful in searching for the structure of large organic molecules. Moreover he had devised a theoretical method for interpreting X-ray derived images of long chain molecules (polymers). This was a highly significant skill.

REBELS WITH A CAUSE

The lead author of the April 1953 letter was James Watson. He had actually already earned his doctorate in bacterial genetics. Then in 1951 at age 23, he arrived at the Cavendish lab to carry out post-doctoral work on myoglobin, an oxygen storing protein found in muscles. Crick, for his part, had been assigned to carry out X-ray diffraction work on hemoglobin (the all important oxygen carrying molecule in red blood cells). Although they came from different backgrounds, Watson and Crick were alike in many ways. Both of them had, for example, read the 1944 book What is Life? by quantum physicist Erwin Schrodinger (1887-1961). In this work, far outside the author’s field of expertise, Schrodinger had speculated that there must be a code of some kind in cells that allows molecules to carry information.

Watson and Crick both suspected that DNA was such a molecule. They were fixated on the problem of DNA structure. It mattered little that they had been forbidden to work on this problem. By gentleman’s agreement between laboratories, the DNA problem had been allocated to the people at King’s College in London. Nevertheless nobody could forbid this irrepressible duo from bouncing ideas off each other, could they?

JUST BECAUSE YOU’RE PARANOID DOESN’T MEAN YOU’RE WRONG

Meanwhile at King’s College, the most capable person carrying out research there in X-ray diffraction was Rosalind Franklin (1920-1958). She was a shy, very work oriented Jewish young lady who suspected that her male Anglo-Saxon fellow scientists were trying to steal the results of her research. In this suspicion she was entirely correct. Unfortunately as a result of her attitude, she had few people-handling skills and thus she found herself isolated and unprotected. She was one of two people allocated to research DNA structure. The other was Maurice Wilkins, who was much better known in the scientific community. He hardly ever spoke to his female colleague.

It was Rosalind Franklin who managed to overcome the difficulties of working with DNA. She designed a special X-ray camera for this work and protocols for handling the molecule. Soon enough, she began to produce X-ray images. What they meant however, she refused to speculate upon until her entire program had been carried out. It was X-ray images that would provide vital clues about DNA structure. She was quite sure about one thing; the images did not suggest a helical structure in DNA.

TWO’S COMPANY, THREE HELIXES IS A CROWD

It is traditional for scientists involved in research to occasionally give lectures to update colleagues on what they are doing. Rosalind Franklin delivered such a seminar in November 1951. Her colleague Maurice Wilkins invited his friend James Watson from Cambridge. Francis Crick did not come because his interest in DNA was too well known. Watson listened carefully, but he did not bother to take notes. That might look too eager. Watson’s recall of what he had heard proved faulty however and progress on the issue was very slow. Then in January 1953, word came that American Linus Pauling was about to publish a proposed structure. This man sent a preprint to his son at Cambridge. The son showed it to friends Watson and Crick. They were relieved to see that Pauling had made a simple but significant error in the chemistry and was proposing a triple helix structure. They had a reprieve which might last a few weeks.

Two days later Watson visited Franklin. The exchange of views did not go well. Watson taunted her that she was inept at X-ray interpretation. He then encountered Wilkins who showed Watson the best image Franklin had ever taken. From it Watson was able to see clear indications of helical structure and even measurements of angles. Wilkins also showed Watson a Franklin research proposal which contained further crucial details. Based on these insights, Watson and Crick solved the DNA conundrum within four weeks, proposed a double helix, and the rest is history.

When they published, they failed to acknowledge any contribution of Rosalind Franklin. She died five years later, never having heard of her contribution to this story. In 1962 Crick, Watson and Wilkins were awarded the Nobel Prize in Physiology and Medicine. The achievement of Watson and Crick reveals how important theoretical analysis is to the solving of many scientific problems. However they could not have done it without the experimental foundation of Rosalind Franklin. Theory and empirical research go hand in hand.

DRIVEN BY AN AGENDA

In the decades that have followed, both Watson and Crick enjoyed long careers. Interestingly, both attribute their success to their atheistic views. James Watson went on to a faculty position at Harvard University where he soon proved himself adept at fund raising and administration. Eventually he became director of the Human Genome Project.

Francis Crick also enjoyed a long career and in his later years turned his attention to the seemingly unrelated issue of human consciousness. In Crick’s mind, however, there was a connection between the human brain and the DNA helix. During an interview with Matt Ridley, Dr. Crick described the connection. Apparently his interest in science came entirely from his atheistic views. Because of his distaste for religion, Dr. Crick said, he set out to research the two main topics often cited as support for religion: namely the gulf between life and nonlife, and the phenomenon of consciousness. As a hardcore materialist, it was Crick’s objective to explain both these phenomena in chemical terms. His hope was to dispense with any excuse for attributing natural phenomena to the work of God. After all, as colleague James Watson once remarked “Every time you understand something, religion becomes less likely” (or so they would both like to believe).

A DESCRIPTION ISN’T AN EXPLANATION

A little reflection on our part, however, will show that Watson and Crick had in no way explained the gulf between living cells and mere organic compounds. Indeed what they had achieved was to describe how information is stored in DNA but they had not explained how that information came to be stored in the DNA molecule in the first place.

Nevertheless, under the mistaken assumption that their explanation did away with the need for a Creator of living cells, Dr. Crick turned his attention to the problem of consciousness. He wrestled with the problem for more than twenty-five years, but still the solution eluded him. One might imagine that after all that time, he might concluded that his program has no hope of success – that he might even grow discouraged with his atheistic agenda. On the contrary, right up until his death, Dr. Crick remained as firmly committed to his position as ever.

Throughout his career, James Watson too has steadfastly declared his atheism. In an interview with editor John Rennie of Scientific American, Dr. Watson confided: “I never thought there was a spiritual basis for life; I was lucky to be brought up by a father who had no religious beliefs.” In another interview he suggested that one of the benefits of DNA research was to provide mankind with godlike powers. Thus he remarked:

“Only with the discovery of the double helix and the ensuing genetic revolution have we grounds for thinking that the powers held traditionally to be the exclusive property of the gods might one day be ours.”

When it was pointed out to him that his sentiments were a far cry from those of the founding Pilgrim fathers, he replied: “America isn’t what it was like when the Pilgrims came here. We’ve changed everything. We’ve never tried to respect the past, we’ve tried to improve on it….”

That’s his opinion at any rate.

NO END TO THE WONDERS TO EXPLORE

It is apparent that from the start, the objectives of Drs. Watson and Crick were atheistic in nature. They were bitterly opposed to religious faith of any sort. For example, Francis Crick resigned as a fellow of Churchill College, Cambridge when that college embarked on plans to build a chapel. He suggested alternatively that a brothel would be nice, a not too subtle put down of places of worship.

The ultimate objective of these two men then was to explain both life itself and consciousness in chemical terms which would completely exclude any supernatural element. Of course in neither instance have they succeeded. The mystery of life cannot be explained in chemical terms. It is indeed ironic that our understanding of DNA has led to a greater appreciation of the gulf between nonliving chemicals and the living cell. No spontaneous or natural process can ever explain how a code such as DNA came to be, or the astonishingly concentrated storage of its contained information. Instead of providing us with an explanation of how we could have come about without God, their discoveries have only help show that we are more “fearfully and wonderfully made” than was understood before.

Thus this objective of atheists Watson and Crick has been met with utter failure. In addition even Dr. Crick admitted that the search for an explanation for consciousness had been frustrating. No solution is in sight even after all those years of study.

Christians for their part, still celebrate the achievements of April 1953. The motives of Watson and Crick were all wrong, but the nature of their information does not depend on attitude whether good or bad.

Book Review: No Christian Silence on Science

No Christian Silence on Science: Science from a Christian Perspective, Margaret Helder.  Edmonton: Creation Science Association of Alberta, 2016.  Softcover, 110 pages.

Many people have heroes.  Also when it comes to science, there are names held in awe:  Galileo, Newton, and yes, for some, Darwin.  I have a scientific hero too, but she’s not as well-known as the other scientists I just mentioned.  For many years, my scientific hero has been Dr. Margaret Helder, a Canadian botanist and prolific writer.  I’ve always admired not only her faithfulness to biblical truth, but also her courage and passion for that truth.  I’m thankful for what God has done through her efforts.

No Christian Silence on Science is a collection of essays illustrating how Christians should think about science.  Dr. Helder helps readers recognize that Christians are up against a clash of worldviews.  She points out some of the pitfalls that inevitably threaten believers who venture into science.  She lays out lessons to be learned from history — for instance, a self-taught naturalist named Philip Henry Gosse.  In his opposition to Darwin, Gosse “showed more zeal than common sense” (page 108).  Dr. Helder also tackles the question of whether Christians who take the Bible seriously can make any accommodations for biological macro-evolution or geological old-earth positions.

This little book is especially going to be helpful for university students taking advanced science courses.  There are sections that are quite technical.  I don’t have any formal science education beyond high school and an intro physics course in university, so the discussion in chapter 2 about “clustered regularly interspaced short palindromic repeats” (CRISPRS) was a bit beyond my ken.  For Christian post-secondary students, chapter 4 is explicitly directed towards equipping them for navigating the academic scientific environment.  Not only is there a helpful academic orientation, but also concrete advice.  For example, Dr. Helder reminds students that at first glance it may appear that creation-based resources are inadequate for answering the challenges encountered at a secular university.  But:  “What the student must remember is that there are conservative scholars who support a young earth position, and there are technical documents in this genre as well” (page 85).  Seek and ye shall find!

However, I don’t want to leave the impression that this book is going to be an impossible read for the non-scientists.  There’s plenty here that’s both accessible and fascinating.  Take two of the appendices to chapter 2.  One is about the echolocation abilities of bats.  The other is about a favourite food of some bats:  tiger moths.  Some species of bat use sound to locate their prey — and this echolocation system is quite sophisticated.  In fact, “some echolocating bats can control the width of the ultrasonic beam which they emit” (page 52).  The tiger moth, on the other hand, is able to evade bats 93% of the time.  One of the ways it does this is through its own generation of high-pitched sounds.  These sounds actually jam the bat’s echolocation system.  Dr. Helder’s conclusion:  “This is clearly a matter of programming in the insect brain as well.  This creature is clearly designed.  Without the hardware, the software would be irrelevant, and vice-versa” (page 56).

If you know a young Christian who’s studying science, this book would be a great gift.  After all, the author takes the Bible seriously as God’s Word and our ultimate authority in life.  She also has the scientific expertise to demonstrate how Darwinian explanations of origins are inadequate.  That one-two punch makes this book highly recommended.

 

The Big Bang and Genesis

bigbangWhen I was a seminary student, we had the privilege of having Dr. Margaret Helder as a guest speaker.  Having grown up in Edmonton, Dr. Helder was not a stranger to me.  She had occasionally been a guest speaker at our Christian school in Alberta.  However, on this particular occasion at the Canadian Reformed Seminary in Hamilton, I heard her say something that I couldn’t recall having heard before.  I don’t remember if it was part of her original presentation or in reply to a question, but she pointed out that the so-called Big Bang and Genesis are incompatible.  I don’t remember the exact reasons she gave as to why that was, but it sounded quite reasonable to me at the time and, since then, I’ve kept it in the back of my mind.

I thought about this again recently as I encountered a book which suggested that the Big Bang and Genesis are compatible.  Gregory Koukl’s new book The Story of Reality is generally a recommended overview of the Christian worldview (a review will be appearing shortly on my blog Yinkahdinay).  In chapter 7, Koukl is answering two objections to the Christian view of God as Creator.  The second has to do with miracles.  After all, creation is a miracle.  He notes that all scientists “pretty much agree that the universe had a beginning.”  That beginning was the Big Bang where “all things exploded into existence in a fraction of an instant.”  Then he says this (page 51):

I know the Big Bang idea is controversial with some Christians, but I think that’s because they haven’t realized how well it fits the Story [the Christian worldview laid out in the Bible], which basically says the same thing.

So according to Koukl, the Big Bang fits with Genesis 1:1, “In the beginning, God created the heavens and the earth.”  Reading this gave me occasion to look a little more into this and refresh my memory as to why Dr. Helder had told a group of seminary students and professors otherwise.

I found this article on creation.com to be especially helpful:  The Big Bang is not a Reason to Believe.  If you don’t have the time or inclination to read the whole article, this chart about sums it up — each flash on this chart represents a conflict between the chronology of Genesis 1-2 and Big Bang cosmology:

russ-humphreys-idea

Does the Big Bang really fit the story that well?  Perhaps if you define “Big Bang” in some way that doesn’t reflect how it’s really being used in astrophysics.  Maybe that’s what Koukl has done.  Or perhaps if you insist that Genesis 1-2 don’t give us a chronologically accurate, historic account of the origins of the universe.  Of course, that second option could find you up against Jesus Christ, who clearly taught that Adam and Eve were created at the beginning (Matthew 19:4).  No, I still think that Dr. Helder was right.  There’s no reconciling the Big Bang and God’s Word.

Wrong questions lead to the wrong answers

Why don’t brilliant scientists see evidence of God’s design in Nature?
Because they deliberately blind themselves to this evidence.

by Margaret Helder

The conflict between Biblical revelation and some aspects of modern science is a longstanding issue, and Christian young people can’t avoid being impacted by this dilemma. What should they believe? Should they accept that creation took place in six literal days, or should they seek some sort of accommodation of Scripture with the teachings of science? Many have anguished over this choice.

The appeal of trying to accommodate to the popular scientific view – the appeal of bundling the Bible with the Big Bang – is clear. After all, don’t objective scientists know what they are talking about? So don’t we need to listen to what they are telling us they see?

Christian vs. secular agendas

In this context, what everyone must understand is that there are no objective scientists. Everyone has starting assumptions. The Christian naturally confesses that God exists, that He is omnipotent and omniscient and has communicated with us. Nature is God’s handiwork. Thus the Christian confesses that we see testimony to God’s work and character when we look at nature. For example we read in Psalms 19:1-3:

The heavens declare the glory of God, and the sky above proclaims his handiwork. Day to day pours out speech and night to night reveals knowledge. There is no speech, nor are there words, whose voice is not heard.

Another famous passage about the testimony of nature is Job 12:7-9:

But ask the beasts, and they will teach you, and the birds of the heavens, and they will tell you, or the bushes of the earth, and they will teach you, and the fish of the sea will declare to you. Who among all these does not know that the hand of the Lord has done this?

When we study biology, we see that God is the creator!

The secular position contrasts sharply with the Christian view. Mainstream scientists maintain that natural explanations can be found for everything. No supernatural input will ever be evident. For example, an editorial in the journal Nature (March 12, 1981) remarked concerning the definition of science: “…one prejudice is allowable, even necessary – the preconception that theories can be constructed to account for all observable phenomena.” Thus the Christian expects to see God revealed in nature, while the secular person says God will never be revealed in nature.

Different expectations prompt different questions

With different expectations come different questions – there is a big difference between what secular scientists and what some Christians will ask about natural systems. And their different questions will result in very different answers obtained.

Square watermelons - web
How does a square melon get square? Newly sprouted watermelons are placed in plastic boxes, and as the melon grows it fill in the available space until this unique shape results.

For example, suppose somebody showed you a photograph of three unfamiliar objects, green in color and square in shape. If you were to ask that person “How did Nature form that?” the only possible response would be some sort of process. However, if you were instead to ask, “Did Nature form that?” then the person has the opportunity to investigate whether or not these square watermelons (which is what the objects turn out to be) had a simply natural origin. Only then could they discover that no, they did not.

Similarly, if a scientist asks, “How did life come about spontaneously?” then the only possible answer is a process. If the same scientist were to ask “Could life come about spontaneously?” in this case he has the opportunity to examine what cells are like and what the biochemical processes in cells are like, and thereafter conclude that life could not have come about spontaneously. Thus the answers obtained from the study of nature depend upon what questions are asked.

No results

There is no issue that more clearly demonstrates the impact of what questions are asked of nature, than the discipline of origin of life studies. Specialist John H. McClendon’s summary of the situation was as follows: “Since we know that life did arise, we are obligated to find mechanisms to accumulate enough organic matter to start life.” Scientists may feel themselves obligated to find such a scenario, but they are having a difficult time finding one nonetheless.

The difficulties of proposing and defending a reasonable scenario for the origin of life were further highlighted by Simon Conway Morris in 2003 in a chapter entitled “The Origin of Life: straining the soup of our credulity” from his book entitled Life’s Solution. Of these chemists who are not discouraged by the results of their experiments, he remarks:

…chemists have devised reaction pathways that can produce reasonable quantities of ribose [needed for one popular scenario], but the sheer complexity of the process and the careful manipulation of the many steps during the reaction make one wonder about its applicability to the origin of life.

Dr. Morris is telling us that the kind of chemical reactions that require fancy manipulation by a chemist do not occur spontaneously in nature (apart from in living cells).

Scientists were still looking for support for the “RNA world” in 2014 when the following description of a possible process was printed in Nature:

After ten rounds of selection and amplification of catalytic molecules; pruning of superfluous sequences; insertion of another randomized segment to create a new pool; and then another six rounds of selection and amplification, a D-ribozyme was isolated that could perform template-directed joining of L-substrates about a million times faster than the uncatalyzed reaction.

One would have to be very gullible indeed to believe that any of this could happen spontaneously. Indeed the article referred to the process as “engineering” which presupposed that an intelligent agent (the chemist) carried out the process.

An article in Nature five years previously had similarly highlighted the difficulties of the RNA world hypothesis, the most popular explanation today for how life could have originated in spontaneous fashion. Matthew W. Powner et al declared:

At some stage in the origin of life, an informational polymer must have arisen by purely chemical means. According to one version of the “RNA world” hypothesis this polymer was RNA, but attempts to provide experimental support for this have failed (italics mine).

The determination of the mainstream scientists to keep looking for a spontaneous solution to the origin of life, even when the results are totally contrary, has long been recognized. But they do not see this situation as a problem. Thus David Deamer remarked in a book review on origin of life theories:

[Author] Harold argues that, notwithstanding the vast literature, progress has gone little beyond the findings of Soviet biochemist Alexander Oparin and British polymath J. B. S. Haldane more than 80 years ago, when they independently argued that Louis Pasteur’s dictum “All life from life” was wrong.

Note that the “findings” of Oparin and Haldane that Pasteur was wrong, were not based on any evidence, (they still aren’t), but on a choice to believe that life can come from non-living chemicals.

Their bias blinds

The secular scientist approaches the study of nature with a specific agenda. Nature is to be interpreted only in terms of matter, energy, and natural processes, even if the results look ridiculous. A prominent geneticist, Richard Lewontin (b. 1929) actually stated this very clearly. In a famous review of a book by Carl Sagan, he wrote:

Our willingness to accept scientific claims that are against common sense is the key to an understanding of the real struggle between science and the supernatural. We take the side of science…. because we have an a priori commitment to materialism. It is not that the methods and institutions of science somehow compel us to accept a material explanation of the phenomenal world, but, on the contrary, that we are forced by our a priori adherence to material causes to create an apparatus of investigation and a set of concepts that produce material explanations, no matter how counter-intuitive, no matter how mystifying to the uninitiated. Moreover, that materialism is absolute, for we cannot allow a Divine Foot in the door.

What Dr. Lewontin said, was that scientists bias their studies so that only natural explanations will ever be obtained. Similarly astronomer Robert Jastrow (1925-2008) equated such an approach as almost a religion for scientists:

Scientists…. believe that every event that takes place in the world can be explained in a rational way as a consequence of some previous event. If there is a religion in science, this statement can be regarded as its main article of faith…

Nothing to do with the truth

It is certainly reasonable to ask how legitimate it is to restrict science to only naturalistic hypotheses. The answer you’ll get to that question depends upon whom you ask. Biologist Leonard Brand (b. 1941) replies that such restrictions are not legitimate.

Our research only answers the questions we are willing to ask, naturalism allows only certain questions to be asked… Naturalism has a powerful biasing influence in science, in steering scientific thinking, and, in many cases, deciding what conclusions are to be reached.

Others point out that secular scientists may restrict what explanations about nature qualify for the term “science” but they cannot at the same time claim, that what they are dealing with is truth. For example, philosophers of science Stephen C. Meyer (b. 1958) and Paul A. Nelson (b. 1958) point out:

Restricting science to naturalistic hypotheses is not an innocuous methodological stratagem [innocent technique] which nevertheless leaves science free to pursue the truth. God, after all, may not have been away on other business when life originated, or humankind came to be.

These men declare that the secular assumption that God did not intervene directly in nature does not make it so. Similarly Calvin College (in Michigan) philosopher of science Del Ratzsch points out that:

If nature is not a closed, naturalistic system – that is, if reality does not respect the naturalists’ edict – then science built around that edict cannot be credited a priori with getting at truth, being self-corrective or anything of the sort.

What Dr. Ratzsch has pointed out is that wrong questions will always elicit wrong answers. Scientific explanations may change (and indeed they do) but the answers will never be any closer to the truth if the wrong questions are being asked in the first place. It is often said that science is “self-corrective” i.e. that errors are exposed and better explanations developed. However the term “self-corrective” is meaningless when the studies are biased from the beginning.

Conclusion

Secular scientists, with their expectations of never seeing God in nature, have confined themselves to mechanistic explanations and interpretations. Such, of course, is the theory of evolution. As Dr. Ratzsch remarks: “… materialists have no viable choice but to view the world through evolutionary spectacles of some sort.” Similarly Dr. Brand tells us: “The evolutionary theory is based on the philosophy of naturalism, and does not consider any hypotheses that involve divine intervention in the history of the universe.”

Influenced by their secular colleagues, many Christians choose a theistic evolution type of explanation for origins. For example, Clarence Menninga (b. 1928, science professor emeritus at Calvin College), wrote in The Banner:

But it is presumptuous and arrogant for us to restrict God’s options by claiming that he could not have used natural processes to bring about certain complex structures and functions, even if we do not understand in scientific terms how that was done.

Thus Dr. Menninga explains the appearance of living creatures in terms of an evolutionary process. He assumes that this is so, contrary to what the Bible says, even though he is unaware of a scientific explanation for the process.

It is evident that if such scientists were to ask different questions, based on the expectation of seeing God’s work and character revealed in nature, they might not necessarily come to any evolutionary conclusions at all. In addition, the concept of long ages is a necessary ingredient in any evolutionary scenario. If there were no process of gradual change (evolution), if organisms were created directly, then there is no need for a long period of past time other than the few thousands of years for which we have historical records.
