“Inferior” design: a proof of evolution?

fly“Suboptimal” design in nature is supposed to be the result of, and evidence for, evolutionary trial and error

by Margaret Helder

Everybody loves to hear about wonderful living creatures with their amazing talents. It is certainly uplifting to learn about Monarch butterfly’s continent-spanning migration, and the toe pads of the gecko that allow it to walk upside down, and the amazing strength of spider silk. Christians enjoy discussing the wonderful designs that we see in nature. And among scientists, these creatures have their fans too. Indeed, there is an entire field in science called biomimicry where scientists try to learn from living creatures in order to produce practical designs for modern applications.

But not everyone is equally enthusiastic about the implications of these amazing talents. Prominent evolutionist Stephen Jay Gould (1941-2002) in 1978 wrote:

“…ideal design is a lousy argument for evolution, for it mimics the postulated action of an omnipotent creator.”

Dr. Gould thus said that everyone should ignore examples of wonderful design and concentrate on phenomena that are below par. He continued:

“Odd arrangements and funny solutions are the proof of evolution – paths that a sensible God would never tread but that a natural process, constrained by history, follows perforce.”

Gould was telling us that he knew how God should act if, that is, God really existed. God, according to Gould, would make everything perfect. And since we know that everything is not perfect in nature then, said Gould, this proves there is no God. This kind of argument, based on assumptions of how God should act, continues to be common in science today. There is thus a lot of interest among scientists, in suboptimal (less than perfect) design. Let us look at some examples to see what the implications are.

THE PANDA’S THUMB

The example Gould discussed in 1978 was the thumb of the Giant Panda. These animals, native to China, eat almost nothing but bamboo shoots. They use their hands to strip off the leaves, leaving the nice tender shoots on which to munch. Their flexible hands are unusual – they have a thumb of sorts, an extra structure produced from an enlarged wrist bone, with associated muscles and nerves.

Gould declares that this extra finger is a “somewhat clumsy, but quite workable solution…. A contraption, not a lovely contrivance.” Here he was declaring that the panda’s thumb was of suboptimal or inferior design, which thus constituted proof that the source of the thumb was evolutionary trial and error rather than from a “divine artificer” (supernatural designer).

A major argument employed by many evolutionists, even today, is to point to suboptimal (inferior) design and to declare that this proves that evolution was the source rather than God. However, what makes something “suboptimal” is an open question. Sometimes a phenomenon that appears less than ideal actually displays superior and unexpectedly sophisticated design. Gould might not like the panda’s thumb, but there is no denying how wonderfully this thumb gets the job done.

INFERIOR EARS?

Another example: the inner ear of humans includes a spirally coiled structure called the cochlea. Lining its interior are very fancy hair cells which, by their motion, amplify the sound. The whole cochlea functions as a remarkably sensitive and finely tuned sound detector. However, at the same time, it also distorts the sound. Might these distortions be considered inferior design?

A study in 2008 (Nature, Nov 13) demonstrated that the distortions actually contribute to clarity of sound. The distortions come from a particular structure connecting the top of the various hair cells. Mice without this connector in their cochlea became progressively deaf.

Who knew distortions were so useful?

STABLE vs. MANEUVERABLE

A recent article published in the online edition of the Proceedings of the National Academy of Sciences (November 4-8) discussed another counter-intuitive (contrary to our expectations) situation. The study was conducted by engineers trying to build efficient robots. This is a large field of research.

The designers want systems that are not only stable but maneuverable. The problem is that these are opposite objectives. In general, the more maneuverable a robot is, the less stable it is. If your robot tips over, clearly it is not going anywhere. Alternatively, the more stable a robot is, the less one can fine-tune what it does – the harder it is to make sudden changes of direction. Thus your robot may be able to proceed briskly straight ahead, but what if you need it to turn a corner or climb over an obstruction? Will it be able to turn, or will it instead tip over?

Animals obviously have no such problems. That’s why engineers have turned their attention to animal locomotion. They ask themselves, how do animals achieve the “impossible” combination of stability and maneuverability? How indeed do actual insects like cockroaches manage their excellent locomotion skills? Biologists may have already observed the solution without recognizing its significance. Why, many biologists have wondered, do animals move in directions that are different from their desired destination? Why, for example, do cockroaches and lizards tilt from side to side as they run forward? An engineer would most likely eliminate these motions, which seem to waste energy, as they do not obviously contribute to the forward motion. Lately, however, mechanical engineers have begun to research how unexpected, “inefficient” movements may benefit these animals.

Insight into this mystery recently came from studies of a tiny fish from the Amazon basin. In order to avoid predators, this fish prefers to hide in various shelters such as tiny tubes. Scientists used slow-motion video to study fin movements of this fish as it finessed its way into its hiding places. At 100 frames per second, a strange situation became apparent. The fish was using one part of the lower body fin to push water forwards, and the other part to push it backwards. This was definitely against common sense since it was like two propellers fighting against each other.

When scientists built a fishy robot, they found that the opposing forces actually improved the stability and maneuverability of their model. The assumption of the engineers that it is wasteful or useless to employ forces in directions other than the desired forward motion had now been proven wrong.

Apparently, the same principle applies to the motion of many other creatures. The take-home lesson is that what, at first glance, appeared to be inferior design (opposing forces) actually turned out to be superior design!

PENGUIN ROCKETS

Another recent robotic study which shows promise is one inspired by the talents of emperor penguins. While these creatures look pretty inept on land, in the water they can accelerate from 0 to 7 meters/second in less than a second (a veritable rocket).

penguin-1024x560-1

One student at Caltech’s Aeronautics Department set out to create new propulsion technologies with high maneuverability and improved hydrodynamic efficiency. The new mechanical design is based on the penguin’s shoulder and wing system and features a spherical joint with various other technical features. Concerning the promise of the study, the student declared that the manner in which penguins swim is still poorly understood. Nevertheless, by accurately reproducing an actual penguin wing movement, he and his collaborators hope to shed light on the swimming mysteries of these underwater rockets (ScienceDaily.com November 14, 2013).

THE FLY EYE

There are many other examples of unrecognized excellence in design. For example, the compound eye of insects and other invertebrates is often considered to be less ideal than our own camera eyes. However, a recent study that modeled the compound eye found that it does offer some advantages over the camera style eye (Young Min Song et al. Nature. May 2, 2013).

Specifically the compound eye provides for an exceptionally wide field of view, and secondly such an eye has a nearly infinite depth of focus. As an object recedes away from the eye, the object becomes smaller, but it still remains in focus. It is apparent that in the case of eye design, there is no such thing as inferior design. There is instead good design that is more applicable to certain applications than to others.

GOD TELLS US TO EXPECT “INFERIOR” DESIGN

Obviously however there are many situations in nature that are less than ideal. This is a fallen world and there are many cases where we see distressing phenomena. The secular argument that a good God would never mandate inferior design is simply not valid. God cursed nature as a result of man’s sin, so we have no reason to expect wholesale perfection, and the former “very good” creation now displays many inferior design choices. For example in Job 39:13-17 we read:

The wings of the ostrich wave proudly,
   but are they the pinions and plumage of love?
For she leaves her eggs to the earth
   and lets them be warmed on the ground,
forgetting that a foot may crush them
   and that the wild beasts may trample them.
She deals cruelly with her young, as if they were not hers;
   though her labor be in vain, yet she has no fear,
because God has made her forget wisdom
   and given her no share in understanding.

Clearly, the breeding behavior of the ostrich is suboptimal but nevertheless designed by God. Yet “when she rouses herself to flee, she laughs at the horse and his rider” (Job 39:18). The strong legs of this bird and her running prowess also come from God. These gifts are a strong contrast to the behavioral deficits of the ostrich.

The evolutionists think they have proven that God did not work in nature. However, since their argument depends upon a discussion (however faulty) of the nature of God, this is a religious argument. Since they claim to have ruled out all religious arguments, then how can they use arguments concerning what God would or would not do – arguments touching on the character of God – to prove evolution? They need to make up their minds. If they want to explore the character of God and why He’d allow brokenness in the world, then let’s open our Bibles.

As for Christians, despite the fallen condition of the world, we can still enjoy and benefit from, and give thanks for, the many wonders of creation as coming from God’s divine wisdom.

The Ambiguity of Biblical “Background” (Noel Weeks)

Screen Shot 2018-09-26 at 10.17.31 PM.png

In this blog entry and the next, I would like to introduce two excellent journal articles by Noel Weeks, both of which appeared in the Westminster Theological Journal. The first, featured here, is from 2010. The second is from 2016. Both are available in pdf online (links below).

 

Screen Shot 2018-09-26 at 10.20.09 PM.png

Noel Weeks is an Honorary Associate in the Department of Classics and Ancient History at the University of Sydney in Australia. He has degrees in both zoology and theology and has taught Ancient Near Eastern history for most of his life.

Back in 2010, in Vancouver, I had the distinct privilege of enjoying a very charming and thoughtful lecture by Dr. Weeks on Christian education. His ability to engage an audience and speak intelligently for 45 minutes or more without any notes astonished me at the time.

The article at hand addresses the use of “background” material informing the study of the Bible. For instance, when the Bible describes God’s creating work, does it do so in ways that might be comparable to other “creation” accounts in the Ancient Near East? What about Abraham taking Hagar to function as his wife because Sarah was barren? Was this common? Or, when God makes a covenant with Abram in Genesis 15 or commands circumcision in Genesis 17, is God making use of existing cultural customs? If he is, what can we learn by doing some “background” study? Such study could be very helpful, but it needs to be kept in its proper place. Scripture alone is the Word of God, and the Word of God is self-attesting and fully trustworthy in itself.

A treasure trove of “background” information has become available in the last century. In the first half of the twentieth century this was used to show the reliability of the biblical text, but in the last fifty years it has been used in much the opposite way. Comparisons to other Ancient Near Eastern “creation” accounts, for instance, have lately led John Walton to argue that the church has misunderstood Genesis for millennia. He argues that the Genesis creation account only tells us about the function of the created things, not their origins. According to him, this view of Genesis 1 matches the Egyptian and Mesopotamian way of telling their creation stories.

Weeks’ article from 2010 was written before Walton’s books and arguments had really begun to gain traction. Yet Weeks’ arguments are pertinent: he points out that the use of this biblical background material to back up the biblical account opened up the likelihood that the same material would be used to break down the biblical account—the methodology was flawed. The Christian must first of all receive the text in faith.

Arguments based on supposed parallels often suffer from the following faults:

  1. The cultures or texts being compared had no contact geographically.
  2. The cultures or texts being compared were from vastly different times.
  3. The point of comparison is too general to be helpful.
  4. The assumption of uniformity across cultures, lands, and times is flawed.
  5. The assumption that biblical authors must have conformed to what was common in their place and time is flawed. This denies the possibility of God’s revelation transcending their time and place, of newness, and of change.
  6. The transmission of the text or practice from the one culture to the other culture is rarely, if ever, explained.
  7. Correlation does not imply causation.

Screen Shot 2018-09-27 at 10.28.00 PM.png

Among the other alleged parallels that Weeks addresses, he speaks to the question of common creation accounts in the Ancient Near East. His comment is very much to the point: “The background to the biblical creation stories has been ‘found’; the problem is whether it has been found in Mesopotamia, Ugarit, Egypt, or a complex mixture” (229–30). As he explains, each of these options presents significant difficulties. In no case have scholars explained how the account of one culture reached another or was used by the other culture. In the case of Egypt, there are even several differing accounts available, so which one is the right candidate as “background” or “parallel”?

Weeks concludes that if scholars are going to read the text of Scripture as if it was locked into its own time and culture, then they need to realize that they themselves as scholars are also locked into their own time and culture (235). Yet scholars constantly act as if they have transcended this problem. This is illogical.

Blame Augustine for “Adam” (II)

Is it true that “no one in the Bible believed that construct of the historical Adam” but that the idea originates with the church father Augustine (354–430)? Such is the assertion of Scot McKnight, a leading NT scholar, in this video from the Canadian Scientific and Christian Affiliation.

Last time we laid out the Scripture texts that consistently identify Adam and Eve as the original couple, from whom the whole human race descended. These texts expose McKnight’s pronouncement to be false, and no Scripture text can be advanced that supports his position. I realize that McKnight is depending not only upon Dennis Venema’s biological study in their co-authored book, but also upon the OT scholar John Screen Shot 2017-11-25 at 4.07.25 PM.pngWalton’s claim that Genesis 1–2 is an account of origins that speaks only of the function and purpose of the parts of creation, not their material or temporal origins. Walton relativizes the message of Genesis 1 & 2 by claiming that he is reading it within its Ancient Near Eastern context. I’ve attended an entire conference listening to Walton and have read some of his books as well as critiques of them. Maybe his views can be explained and critiqued in a future blog, but aside from Walton’s treatment of Genesis 1 & 2, all the other Scripture texts I advanced last time clearly treat Adam as a real historical person who was the first man, and origin of the human race. Therefore it would not in the least surprise readers of the Bible to find writers from the early church saying the same thing. But recall McKnight’s second assertion, “I think we can blame this one on Augustine and those who followed after him, that they created this construct, that we need salvation because of the sin nature that has been passed on from Adam to everybody else.” If McKnight is correct, we would not find writers prior to Augustine holding out Adam as a real historical person who passed on sin to us.

Irenaeus, Against Heresies (c. A. D. 180)

Screen Shot 2017-11-25 at 4.05.42 PM.png
Irenaeus (c. 130–c. 202)

Let me highlight one early church apologist who does the very thing McKnight says didn’t happen. Irenaeus was a student of the apostolic father Polycarp, who himself had sat at the feet of the apostle John (all three are connected to Smyrna in Asia Minor). Irenaeus particularly opposes the Gnostic heresies in his book Against Heresies. One of their teachings was that material reality came about by a mistake or defect by some lesser divine being, and was not intended by the uppermost First Principle or highest “God.” Salvation therefore now involves the escape of “us,” who are like little sparks of the divine currently trapped in material bodies, and such escape is achieved by learning the higher mysterious system of the Gnostics. Gnostics therefore tended to say that Christ only “seemed” to have a human nature. They then took disciples like Thomas and wrote “gospels” in his name, praising his doubt. In their Gospel of Judas, Judas’s greatest deed, praised by Jesus himself, is to secure Jesus’ death, so that Jesus could escape from his material body. In that context Irenaeus found it necessary to affirm Adam, Jesus, and us all as historical persons with material bodies. He also strongly affirmed the resurrection of the body, a very counter-cultural teaching in his day.

Let’s see what Irenaeus writes in Against Heresies, Book 3, chapter 23. In this first quotation he is arguing against some false teachers who asserted that the rest of humanity could be saved, but not Adam.

But this is Adam . . . the first formed man . . . and we are all from him: and as we are from him, therefore have we all  inherited his title. But inasmuch as man is saved, it is fitting that he who was created the original man should be saved (3.23.2).

Irenaeus then affirms that Adam’s captivity to sin and death was inherited by all humanity, when he writes,

For it is too absurd to maintain, that he who was so deeply injured by the enemy, and was the first to suffer captivity, was not rescued by Him who conquered the enemy, but that his children were—those whom he had begotten in the same captivity (3.2.32).

He illustrates this by speaking of how unjust it would be to rescue children from their captors while leaving the parents under the power of those same captors, to do as they please. What Irenaeus means by this captivity is something he explains in the preceding section, where he writes that Satan made Adam captive by “bringing sin on him iniquitously, and under colour of immortality entailing death upon him,” and, further, that when God rescued the captive Adam, he was “loosed from the bonds of condemnation” (3.23.1). Though Irenaeus doesn’t use the language of original sin and doesn’t distinguish mediate and immediate imputation, he certainly understands that Adam’s sin had brought him and all humanity under God’s condemnation.

A bit further on, he states that God put enmity between Satan and the woman, and that it was to be continuous until the promised Seed of the women came, born of Mary. To that Seed would apply the promise of Psalm 91, that, “You shall tread upon the lion and the cobra; you shall trample the great lion and the serpent” (Ps 91:13). In Irenaeus’s version, the translation of “serpent” was “dragon,” and either term is taken in Scripture to refer to Satan (see Rev 12:9). Irenaeus then interprets the text as follows:

indicating that sin, which was set up and spread out against man, and which rendered him subject to death, should be deprived of its power, along with death, which rules [over men]; and that the lion, that is, the antichrist, rampant against mankind in the latter days, should be trampled down by him . . . wherefore, when the foe was conquered in his turn, Adam received new life; and the last enemy, death, is destroyed 1 Corinthians 15:26, which at the first had taken possession of man (3.23.7).

He adds, finally, that if Adam, as the lost sheep, had not been found and saved, “the whole human race [would] still [be] held in a state of perdition” (3.23.8).

Later, in Book 5 of Against Heresies, Irenaeus again affirms Adam as the first created man, “For in the same way the sin of the first created man (protoplasti) receives amendment by the correction of the First-Begotten” (5.19.1). The historical reality of Adam is further affirmed by Irenaeus’s teaching that just as the Lord Jesus Christ died on the sixth day of the week (Friday) as the Passover Lamb, so Adam sinned on the sixth day of the week of creation (5.23.2).

I suspect that one could read more widely in the apostolic fathers and early church apologists to find more about their teaching regarding Adam, but our perusal of one treatise of Irenaeus shows that McKnight’s assertion about Augustine is incorrect. Irenaeus wrote this more than 200 years before Augustine. Again, we should not be surprised, for, like us, these men were reading and explaining the Word of God. The clear message of Scripture itself is that Adam and Eve were real, historical people, that the entire human race descended from them, that Adam and Eve sinned and thereby dragged all humanity into condemnation, that our Lord Jesus Christ himself inherited the same human nature, though without sin, and that in that body he paid for sin. Therefore those who believe in him shall rise again to new life in body and soul, to live with God in a new material creation, forever.

Blame Augustine for “Adam” (I)

Here’s the first part of our response to the assertion that “no one in the Bible believed that construct of the historical Adam” and that the church father Augustine (A. D. 354–430) is really to blame for this construct.

The assertion is made in this short video clip from the Canadian Scientific and Christian Affiliation, wherein Scot McKnight explains seven assumptions people have when they ask him whether he believes in an historical Adam. He states that their question operates on seven principles or ideas, namely that:

  1. Adam and Eve were two actual, real, solitary human beings created out of nothing or of dirt;

    Screen Shot 2017-11-25 at 3.54.10 PM
    Scot McKnight: Wikipedia
  2. That a biological or procreational connection exists between Adam and Eve and all humans that follow;
  3. That there is an implied DNA genetic connection between Adam and Eve and the procreation of all humans;
  4. That Adam and Eve sinned and thus died;
  5. That Adam and Eve transmitted their sinfulness to all humans that followed;
  6. That therefore all humans need salvation from this sin;
  7. That the church must therefore preach the gospel of salvation and this gospel is at risk if we deny historical Adam.

Exactly right! He summarized our position at Creation without Compromise rather well.

It’s immediately after listing these seven principles that McKnight asserts, “No one in the Bible believed that construct of the historical Adam.” He specifies that no one between Moses and Paul believed it. Then he tells us that the church father Augustine is really to blame. McKnight has been making this pronouncement lately in support of a book he co-authored with Trinity Western University’s Dennis Venema. In a Biologos interview last February he wrote about, “the so-called ‘historical Adam,’ which is a theological construct in the history of the church but which was not believed by any single author in the entire Bible.”

In response, I will simply supply the biblical data. In my next post I will show that long before Augustine (354–430) the early apologist Irenaeus (c. 130–202) clearly and uneqivocally argued for the very historical Adam that McKnight denies.

No one in the Bible believed in an historical Adam? Really? 

Besides the obvious account in Genesis 1 and 2, Scripture also says:

When God created man, he made him in the likeness of God. He created them male and female and blessed them. And when they were created, he called them ‘man.’ When Adam had lived 130 years, he had a son in his own likeness, in his own image, and he named him Seth . . . When Seth had lived 105 years, he became the father of Enosh . . .” etc. (Gen 5).

This is the first of many genealogies, all of which refer to real people. No genealogy in Scripture that goes all the way back to the beginning ever begins with any human but Adam (Compare 1 Chron 1:1; Luke 3:38).

When men began to increase in number on the earth . . . (Gen 6:1).

This verse clearly assumes that it took all the generations of Genesis 5 before the number of humans began to increase, for the human race began with one human pair and only multiplied through the generations. We are never told of a believer in the rest of the OT who challenged or doubted these genealogies, least of all the beginning with Adam and Eve.

But God destroyed the rebellious human race entirely, to start over with Noah. Thus we read,

These were the three sons of Noah, and from them came the people who were scattered over the earth . . . From these the nations spread out over the earth after the flood (Gen 9:19, 32).

What happens after Noah parallels what had already happened after Adam, as recorded in Genesis 5 and 6. Many more texts speak of Adam as the source of the human race, our first father, and of Adam and Eve as those who were from the beginning.

Your first father sinned; your spokesman rebelled against me (Isa 43:27).

Like Adam, they have broken the covenant—they were unfaithful to me there (Hos 6:7).

“Haven’t you read,” Jesus replied, “that at the beginning the Creator ‘made them male and female,’ and said, ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh’ ? So they are no longer two, but one. Therefore what God has joined together, let man not separate” (Matt 19:4–7)

From one man he made every nation of men, that they should inhabit the whole earth (Acts 17:26).

Enoch, the seventh from Adam, prophesied about them (Jude 1:14).

Besides these texts one encounters the famous teachings of the Apostle Paul about Christ and Adam. In Romans 5, Paul wrote about death reigning “from Adam to Moses” and that Adam sinned by “breaking a command” (Rom 5:14). Adam was as real to Paul as Moses; further, the Genesis account of the fall into sin was treated by him as historical truth (the same occurs in 1 Tim 2:13–14 when Paul speaks of Adam being formed first, then Eve, and of Eve sinning first, then Adam). Paul then argues from the universal effects of Adam’s sin—the many died, and death reigned through the one man Adam (Rom 5:15, 17)—to the abundant grace and righteousness that came by the other “one man,” Jesus Christ (Rom 5:18). In 1 Corinthians 15 Paul called Christ the “Second Adam” inasmuch as “in Adam all die, so in Christ will all be made alive” (1 Cor 15:22), and, “The first man Adam became a living being; the last Adam, a life-giving spirit” (1 Cor 15:45), and, “just as we have borne the likeness of the earthly man, so shall we bear the likeness of the man from heaven” (1 Cor 15:49).

McKnight’s assertion cannot stand against the clear evidence of Scripture. He makes his rather odd pronouncement only after accepting his co-author Venema’s arguments for the validity of biological evolution. McKnight even admits that anyone who doesn’t accept Venema’s arguments in their co-authored book (wherein, incidentally, the scientific arguments precede), need not bother with his own arguments. How odd, that a New Testament scholar would let a scientist’s conclusions form the starting point of his own positions, rather than the very Bible that he has been trained to interpret!

The case of the shrinking elephant tusks

elephantLast year I spent some time reading through Richard Dawkins’ The Greatest Show on Earth: The Evidence for Evolution with a friend. As Dawkins explains in his preface, while he has written a number of books about evolution, “I realized that the evidence for evolution itself was nowhere explicitly set out, and this is a serious gap that I needed to close.” So in this book he sets forth his best case for evolution, making it an intriguing book to contend with.

Some of his arguments have ready answers, and some do not, and my hope in sharing both the answered and the unanswered is that readers may be better prepared to contend with evolution, neither overestimating nor underestimating the challenge it presents.

At some point I hope to include a chapter by chapter response, but I’m going to begin with Chapter 5, because it is one of the most interesting. Dawkins titled this chapter “Before our very eyes,” and it is here that he shares what he sees as examples of evolution that occurred “so fast…we can see evolution happening with our own eyes during one human lifetime.”

Today we’ll take a look at the first example he gives, about elephant’s tusks.

Chapter 5: Example #1 – THE CASE OF THE SHRINKING ELEPHANT TUSK

Dawkins believes the African elephant may have “evolved” a smaller tusk size in the space of 33 years. From 1925-1958 the Uganda Games Department monitored tusk size and noticed a decrease in size that was “highly statistically significant, which means that it is almost certainly a real trend, not a random chance effect.”

Why are elephant tusks shrinking? Dawkins proposes that, because “hunters tend to pick on the individuals with the largest tusks” this “means that, at least in theory, smaller-tusked individuals will be at a selective advantage.”

While acknowledging this is merely a plausible explanation, and there may be others unrelated to natural selection he concludes “I am inclined to take seriously the possibility that this is a true evolutionary trend.”

Response

Dawkins repeatedly speaks of creationists in his book – Greatest Show on Earth is supposed to be an answer to them – but this example left me wondering just how familiar he was with creationists and their arguments.

Why?

Because this example of “evolution in action” is one creationists could use to support our position. Creationists don’t find natural selection controversial. We believe change does happen, and quickly – after all, we’re the folks who believe that the vast variety of dogs we see today came from just a few kinds present on the ark!

So if elephant tusks are trending smaller over the course of a generation or two, that fits in well with the creationist model.

What it doesn’t do is offer any sort of evidence for the molecule-to-man form of evolution Dawkins supports. A smaller average for tusk-size is a horizontal change – no new information is needed, just selection from what’s already present. But for evolution of the sort Dawkins defends we need an explanation for a vertical change – how beings can grow in complexity, evolving from that single-celled creature to something elephant-size.

Either Dawkins is unaware of that fact creationists also believe in natural selection – which would mean he really needs to do his homework! – or he is knowingly and deliberately pulling a bait and switch here, presenting one form “evolution” in which the word means little more than “change” and offering that up as if it were proof for the very different sort of “molecule-to-man” evolution.

For more on this point see:
