by Margaret Helder
Sometimes we forget that scientists like to be amused just as much as other individuals, and the illustration in the November 20/08 issue of Nature is certainly amusing. You see five ducks swimming serenely in a row. Above the water line, they are all identical but below the surface one duck is propelled along by a massive tricycle, one has extremely long legs with webbed feet, one has normal legs, one is propelled by a motorized propeller and the last one sits serenely on top of a gigantic octopus.
It all makes one think of the sentiments expressed by “Little Buttercup” in the English operetta H.M.S. Pinafore. She warbles:
Things are seldom what they seem,
Skim milk masquerades as cream…
Black sheep dwell in every fold
All that glitters is not gold.
The amusing illustration in the Nature article, was actually promoting a similar idea. Organisms may look similar on the outside, it declares, but on the inside, their genetic information may be vastly different.
Why does this matter? Well, it is certainly contrary to evolutionary expectations.
As scientists first started building up a database of DNA coding in various organisms, they knew what they expected to find. Based on evolution theory, they expected that organisms that seemed to have a close evolutionary relationship would exhibit similar DNA codes, and those with a remote connection would show much different collections of code.
In previous generations, scientists looked for similarities in form and function among organisms to draw conclusions about evolutionary relationships. Thus catlike animals would all be placed in the same group. Obviously the experts expected that the results of DNA coding studies would reflect the relationships already established on the basis of similarity in shape and biology. But often that’s not what happened.
The illustration of the ducks, so similar above the water line, represents the form and function of organisms. The vastly different controlling mechanisms below the water represent the here-to-fore hidden differences in the DNA controls inside organisms.
The first sign of unfulfilled evolutionary expectations was when the DNA from a spectrum of organisms was compared. Often the most similar DNA coding was not found among organisms that looked the most similar.
SIMILAR APPEARANCE ≠ SIMILAR DNA?
This discovery can also be compared to an adult assembling two children’s toys. The first box is opened and various component parts fall out along with an instruction sheet. The brave parent duly sets to work and assembles the toy.
Now imagine a second box is opened and a similar toy needs to be assembled. The parent thinks this one should be easy, but alas, he discovers the component parts are all differently shaped and the instructions are different too.
However in due course the second toy is assembled, and it looks and works much like the first toy. If the parent didn’t know that the insides of the two toys were very different, he might have thought they came from the same company. But after seeing the instruction sheet and all the parts, the parent realizes that these two toys must have come from totally separate sources. Even if the first company had wanted to produce a slightly more elaborate model, it would not change the basic components and instructions. It would merely modify the initial program as required.
It is the same with DNA coding in an organism’s cells. Even if the end result looks and works the same, if the instructions and component parts in the cell are very different, we suspect that the organisms have entirely separate sources, or lines of descent.
SIMILAR DNA ≠ SIMILAR APPEARANCE
The response of the scientific community to this unfulfilled expectation was to change the groupings of organisms so that the pattern of DNA differences once again gave a picture of gradual change.
The problem with this solution however is that the new groupings did not make much sense. Now creatures were grouped together as closely related, in an evolutionary sense, that did not have much in common at all. Hence we now have a classic “conflict between molecules and morphology [shape].” As a result, over the past twenty years, we have seen a “radical re-ordering of relationships” among many animal groups (Nature Feb. 12/09 pp. 812 and 816). The same holds true for plants.
So scientists have rearranged their groupings, often in illogical ways, to make the DNA fit an evolutionary scenario. The ducky illustration, however, applies more closely to other problems for evolution theory.
Biochemists firstly noticed that many creatures which have few characteristics in common, nevertheless have many genes which are “virtually identical” (Nature Nov. 20/08 p 300). This can be made to fit both evolution theory and design. Evolutionists interpret this as showing lines of common descent, even if very remote. Meanwhile creationists understand this as showing God’s choosing to use some similar elements in otherwise very different creatures.
But at the same time, the experts have found “closely connected species can connect up their genes in very different regulatory networks while keeping the end result deceptively unchanged” (p. 300). Not only have the scientists found that similar organisms may use genes in different ways, but they may even use entirely different genes to produce the same result (p. 301).
This discovery of very different codes in organisms that appear so similar is, of course, not predicted by evolution theory. Naturally these experts are looking for explanations that will still fit their theory. Thus:
“Now researchers are trying to understand how evolution finds the solutions it does, and why. Some think that this ‘underground’ variation was selected for. Some think it appeared by chance” (p. 300).
When scientists appeal to chance for an explanation, it means that they have no explanation.
WHAT’S YOUR PRESUPPOSITION?
The article in Nature declares that the situation “feels very counter-intuitive.” But is it?
It all depends upon one’s basic premises. If evolution is the basis for one’s interpretation of nature, then the results do not make sense: very similar organisms (often microorganisms) using very different molecules to achieve the same result.
It is obvious that many DNA data do not fit evolutionary expectations. However, the scientists involved simply look for alternative evolutionary explanations. It seems evident that this irregular pattern of DNA coding better fits an explanation involving intelligent choices by God the Creator.
The evolutionist may retort that this does not prove the case for creation. Fair enough. There is no proof to be had in science. The evolutionists claim that all data can be accommodated within their worldview – this is not proof, but preference. Similarly we insist that all data fit Biblical revelation. In the case of DNA, the information from nature does not fit evolutionary expectations very well at all. It does fit the creation model better.
Don’t expect ducks, however, to show the scale of internal diversity illustrated in the Nature article. That was merely for purposes of illustration. However, if anyone sees a duck driven by a propeller, let me know!
This is an edited version of an article that first appeared in September 2009 issue of Reformed Perspective under the title “On ducks and DNA.” Dr. Margaret Helder is the author of No Christian Silence in Science, a book every Christian teen considering a career in Science should read before heading off to university.
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.
Busy bees. Dazzling dragonflies. Meddlesome mosquitoes. They all have the most amazing flying abilities. How do they do it? We are happy to offer a new article about God’s marvellous creation which explains some of the secrets of insect flight, supplied to us by Mr. Martin Tampier.
Martin is a professional engineer and energy consultant in Laval, Quebec. He is also a hobby photographer fascinated by insects, as the amazing close-ups of flying insects in the article demonstrate. He has already published elsewhere on God’s amazing creation. We thank him kindly for this article and trust that readers will praise God as they learn more about how insects fly.
Research around insect flight is on-going and many mysteries still need to be solved. However, some of the complicated features of insect wings are already being copied for man-made technology, including the development of micro-aerial vehicles—ironically modelled after the ‘primitive’ flying of dragonflies.
So while they may not recognize insects as divinely designed, researchers are confirming that they are incredibly complex and use extremely sophisticated physical mechanisms. To date, even the most amazing modelling software is insufficient to properly show how they achieve all of their amazing feats.

When 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:
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.
Evolution’s Achilles’ Heels
Creation Book Publishers, 2014
Edited by Robert Carter
Several months ago, Jon Dykstra reviewed the documentary that was developed in conjunction with the book Evolution’s Achilles’ Heels. I recently had the opportunity to attend a presentation by Richard Fangrad, CEO of Creation Ministries International’s Canadian branch. There was a book table at the event (which is always a draw for me), and this was one of many very worthwhile resources on offer. In his review, Jon gave the documentary a 10/10 rating, and I can only concur that the book is every bit as valuable in its own way as the documentary is.
There are eight “fatal flaws” to the theory of evolution that are addressed in depth by nine Ph.D. Scientists, including Dr. Jonathan Sarfati, Dr. Emil Silvestru, and others. As in the documentary video, the flaws dealt with are:
- Natural selection
- Genetics and DNA
- The origin of life
- The fossil record
- The geologic record
- Radiometric dating
- Ethics and morality
In his foreword, Dr. Carl Wieland reminds us that the issue of origins is predicated on interpretation of the available evidence, and not on the evidence itself. His insights on this issue are important and worth citing:
“This whole controversy, incidentally, has never been about unearthing ‘facts for creation’ vs ‘facts for evolution’. When it comes to matters of history (as opposed to experimental or operational science, the science that concerns itself with how the world works), the issue has never been the facts so much as their interpretation. We all have the same world – the same ‘facts’… And philosophers of science have long reminded us… that raw, uninterpreted facts never speak for themselves. As the late Harvard professor, Stephen Jay Gould, once wrote, ‘Facts do not “speak for themselves”; they are read in the light of theory.’”
The nine scientists who contributed to this book begin with the following presuppositional framework, in the words of Dr. Wieland: “the straightforward truth of the Bible, in particular the Genesis record, affirmed and taught by the Lord Jesus Christ and authenticated by His rising from the dead.” This starting point, even more than the PhD’s piled up behind the names of the authors of this volume, makes Evolution’s Achilles’ Heels a very worthwhile resource.
This is particularly true for Christian students who will certainly have to wrestle with these issues as they prepare to engage in post-secondary science studies, and deal with them on a foundational level, not merely on an issue-by-issue basis. Given the often technical content of the eight chapters in this book, the material is well-presented, neatly laid-out, and accompanied by a number of helpful graphs, charts, and illustrations. Highly recommended without reservation!

Blaise Pascal once quipped that he had written a long letter because he hadn’t had time to write a short one. In this booklet it is evident that authors John Byl (who blogs on evolution and creation at Bylogos) and Tom Goss put an enormous amount of time and effort to boil down the key issues of the origin debate.
In just 42 pages they gave an overview of:
- the difference between historical and operation science
- why secular scientists deny miracles as a matter of dogma
- why many professing Christian scientists do, but shouldn’t, deny miracles
- the basics of materialism and naturalism
- what the various origins positions are
- why Christianity is incompatible with any form of evolution
- how dating methods can be unreliable
- what books would be good for further reading
And that isn’t even all of it!
Both authors are professors, and one, John Byl, is Canadian Reformed. He has his Ph.D in astronomy, and if this slim book has you ready for more, then you’ll want to take a look at his larger and more comprehensive God and Cosmos: A Christian View of Time, Space, and the Universe. But this smaller book, at just 42 pages, is an ideal size to give to any university student, or anyone looking for an introduction to the origins debate. You won’t find any better!
The book concludes with Resource Pages that list two dozen books – these are the very best books on various aspects of the origins debate. So not only is this is an excellent introduction, it also points you to where you can go for much much more.
