Panda thumbs its nose at the dysteleological arguments of the atheist Stephen Jay Gould
by John Woodmorappe
When confronted with the obvious evidence of intelligent design, evolutionists usually try to deny the existence of a Designer by calling attention to supposed flaws in living things, that is, dysteleology. Such arguments are vacuous, and merely try to change the subject. It is as if the evolutionist had found a watch on the beach and tried to deny the existence of a watchmaker by changing the subject from its beach-related origins to one wherein he asserts that the watch has flaws or limitations in its construction ‘that no watchmaker would ever produce’.
Apart from presuming knowledge of what a watchmaker would or would not do, it confuses the whole issue. The point is why there is a watch on the beach in the first place! Evidence indicates that wind, water, sun, and sand are incapable of explaining the existence of the watch. Whether or not it is ‘well-designed’ (whatever that is supposed to mean, and according to someone’s opinion) is quite irrelevant. Clearly then, the ‘poor design’ of the watch is nothing more than a red herring designed to divert attention from the inability of beach-related processes to account for the existence of the watch on the beach.
The panda has an odd forelimb arrangement which it uses to handle and eat bamboo.1,2,3 It has the normal five digits, none of which are opposable to each other. In addition, it also possesses a unique enlargement of two wrist bones which, in effect, gives it seven ‘fingers’. These two ‘digits’ come into play whenever the panda uses them to grasp the bamboo in a pincer-like movement of the ‘digits’. Owing to the superficial resemblance of one of the enlarged-wrist-bone ‘digits’ to the human thumb, this appendage has commonly been called the panda’s ‘thumb’.
Harvard’s Stephen Jay Gould, who is one of the world’s foremost evolutionists (and a self-confessed atheistic Marxist), has resorted to dysteleological argumentation. Writing a magazine article1 that has subsequently been reprinted in a book,2 he cited Darwin’s opinions on orchids, and then moved on to pandas and their ‘thumbs’. The premises of Gould’s argument can be summarized by quoting him, and adding numbers [in brackets] in order to expeditiously refer to his premises. He asserts the following:4
‘[1] If God had designed a beautiful machine to reflect his wisdom and power, surely he would not have used a collection of parts generally fashioned for other purposes. [2] Orchids were not made by an ideal engineer; [3] they are jury-rigged [4] from a limited set of available components. [Conclusion] Thus, they must have evolved from ordinary flowers.’
Gould then applies the same premises to the panda’s ‘thumb’:5
‘The panda’s thumb provides an elegant zoological counterpart to Darwin’s orchids. [4] An engineer’s best solution is debarred by history. [1] The panda’s true thumb is committed to another role, [4] too specialized for a different function to become an opposable, manipulating digit. [4] So the panda must use parts on hand and settle for an enlarged wrist bone and a somewhat [5] clumsy, but workable solution. [2] The sesamoid thumb wins no prize in an engineer’s derby.’
Gould’s premises can be reworded and schematized as follows:
1. A Creator God should not design structures that are composed of close morphological analogues of structures found in other organisms. In other words, a Divinely-designed orchid pollination system should be constructed completely different from the general arrangement of flower parts, and the panda’s thumb should be completely different from the skeletal structure of a tetrapod appendage.
2. Human engineers do not modify pre-existing structures when designing new structures. Therefore, no sensible human engineer would construct something like the orchid’s pollination system or the panda’s thumb.
3. The structures in question are jury-rigged.
4. Evolution is limited in what it can do to a structure: It can tinker with preexisting structures but is generally constrained from originating de novo living structures.
5. The structures are functional but inelegant.
[Conclusion] Therefore, the structures in question could not have been created but must have evolved.
Let us now dissect all of these premises. Premise [1] is completely untestable. There is no way of knowing, apart from revelation (which we do not have about this issue), the specifics of what God would or would not do when creating something. Nor is it clear why He ‘should’, according to Gould’s opinion, constantly create de novo structures in things that He makes. ReMine,6 who has analyzed this question in detail, reminds us that re-using the same essential designs is a matter of simplicity.
In contrast to the first premise, premise [2], can be tested, and can be shown to be totally false. Human engineers do in fact modify ‘homologous’ preexisting structures all the time (or at least create the appearance of having done so). Homologous structures are those which occupy the same ‘location’, in an otherwise-comparable structure, in the form of a different component. Thus, the steel wedge of the axe is homologous to the steel plug of the heavy hammer. The flat surfaces of the sausage-holding tong are homologous to the cutting wedges of the scissors. The wheels of the roller skate are homologous to the blades of the ice skate.
In tracing human history, we would probably find that at least one engineering solution had served as an inspiration for the invention of its ‘homologue’. Perhaps, for instance, someone had suggested that the scissors’ sharp edges be dulled in order for the ‘new scissors’ (later called tongs) to be able to hold hot food objects instead of cutting them.
Now, let us take this reasoning further. If we were to impose evolutionistic preconceptions onto man-made tools, we could say, for example, that the wedges of the scissors are homologues to the flat surfaces of the tongs, and the former therefore underwent evolutionary modification and formed the latter. This is analogous to Gould’s thinking, wherein the panda’s thumb had arisen from relatively small modifications of the basic ursine pattern of forelimb muscles and bones.7
Let us step back and examine what this type of thinking rests upon. It is plain to see that Gould’s argument begs the question. To say that the panda’s thumb is a modified sesamoid bone already presupposes that the panda evolved from an ursine ancestor having a ‘normally small’ sesamoid wrist bone. Hence the circle of reasoning closes whenever Gould uses the assumed evolutionary ancestry of the panda’s thumb as evidence against creation and for evolution.
With premise [2] debunked, its subsidiary premise immediately undergoes the same fate. It is most certainly not beneath engineers’ dignity, intelligence, or creativity to construct structures that contain homologues of each other. Furthermore, the related premises are just so many gratuitous assertions. Thus, whether or not the structures would win in an engineer’s derby is, of course, moot. Whether or not they are inelegant [5] is subjective – nothing more than a matter of opinion. What if, following Gould’s thinking, someone were to say that tongs constitute such an inelegant modification of scissors that no intelligent designer would make something like that!
Let us now examine the argument about jury-rigged structures [3]. What exactly is meant when someone says that something is jury-rigged? To most people, the term connotes one or both of the following: a) something co-opted from another, normal function (for example, the use of a plastic card – which of course normally serves as a license to obtain credit – in order to tighten a loose screw when one lacks a screwdriver); b) something performing a much-inferior function when contrasted with the device which was designed to perform the function in question (for instance, the plastic credit card is much inferior to the screwdriver in applying a torque to the screw, and hence tightening it properly).
To determine if something is jury-rigged, then, we must first know the correct functions of the objects involved. Thus, we know about credit-card ‘screwdrivers’ being jury-rigged only because we already know that plastic cards are normally used for securing credit, and we likewise already know that metallic screwdrivers are designed for turning screws. To assert that the panda’s thumb is a jury-rigged solution would be valid if and only if we already knew that the relevant skeletal elements were ‘meant’ for some other function and if and only if we already knew what a ‘properly-designed’ panda’s forelimb should look like.
Clearly, Gould’s argument presupposes knowledge that he does not have. To the extent that he ‘knows’ that the skeletal elements were ‘meant’ for other purposes, Gould is again begging the question by assuming an ursine evolutionary origin for the panda. And when it comes to the question of what a non-jury-rigged panda’s thumb should look like, Gould cites the fully-opposable human thumb.5 But his argument breaks down as soon as we contrast the respective usages of the two kinds of thumbs. Pandas do not paint, type, write, or do countless other things which humans do with their hands.
Thus they do not need an opposable thumb, so it is in no sense jury-rigging for them to have a thumb much inferior (in some, but not all respects) to that of humans. Furthermore, notably unlike the use of credit cards to tighten screws, the panda’s thumb is more than adequate for the role of handling bamboo. A recent study by a team of Japanese investigators makes this fact vividly obvious:
‘The three-dimensional images we obtained indicate that the radial sesamoid bone cannot move independently of its articulated bones, as has been suggested, but rather acts as part of a functional unit of manipulation. The radial sesamoid bone and the accessory carpal bone form a double pincer-like apparatus … enabling the panda to manipulate objects with great dexterity … . We have shown that the hand of the giant panda has a much more refined grasping mechanism than has been suggested in previous morphological models.’3 [Emphasis added]
Were the Creator to have endowed the panda with a human-like thumb, this would be an instance of over-design. It would be akin to using a precision laser-cutter for opening tin cans when an ordinary can-opener can do the job adequately.
Clearly, then, the premise about the jury-rigged panda’s thumb [3] fails on both counts. Not only does it lack independent proof of a co-opted usage of skeletal elements, but it also spectacularly fails in the implication of jury-rigged devices being ones that are marginal in function.
What about the argument that evolution can only ‘tinker’ with preexisting skeletal elements (in the case of the panda’s thumb, with ursine forelimb skeletal elements) only to a very limited extent [4]? At first the argument sounds superficially plausible. After all, essentially the same pentadactyl plan exists in human hands, the panda’s ‘hands’, the flippers of whales, and in the wings of most volant vertebrates. But the argument collapses once we examine the entire range of vertebrate skeletal arrangements.
A recently-discovered extinct gliding reptile, Coelurosauravus jaekeli,8 possessed ‘wings’ (gliding apparatus) which were not the usual modification of tetrapod forelimbs as seen in birds, bats, etc. Nor were the wings modifications of ribs or other thoracic elements in any way. They were not duplicate copies of forelimbs. Instead, the wings were completely de novo structures composed of thin hollow rods of bone covered with flesh, emanating from the reptile’s rib cage. And although Coelosauravus is claimed to be ‘the oldest known flying reptile’8 (by evolutionary ‘dating’ methods), it had these fully formed structures, while the fossil record, as usual, lacks any ancestral transitional forms.
These structures falsify the premise about evolution being ostensibly limited to relatively slight modifications of previously-existing structures. They also nullify Gould’s argument that the panda’s thumb ostensibly ‘had to’ evolve in the manner that it did because of its supposed specialized ursine ancestry. If not, they at least force the evolutionist to use his ‘limited evolution’ argument in a manner that is not self-consistent with the world of nature.
If even one premise of an argument is false, the argument is unsound, that is, the conclusion is not proven.9 With the complete failure of the first four premises of Gould’s argument, it is obvious that the conclusion–that the structures had to evolve and were not specially created–is not proven. There are no grounds whatsoever for contending that the panda’s thumb is some sort of non-designed contraption. Instead, it has its own precise function,3 which can only point to God the Creator.
In the beginning of this article, I had pointed out that dysteleological arguments are nothing more than smokescreens designed to hide the failures of naturalistic explanations by changing the subject. In like manner, it should be noted that Stephen Jay Gould spends little time providing solid evidence of how the panda, the panda’s presumed ancestors, the ancestors of the ancestors, and the first life were all supposed to have evolved. And no wonder.

of
Patrick Korten,
Vice President, Cato Institute
before the
Subcommittee on Civil Service
Committee on Government Reform and Oversight
United States House of Representatives
Civil Service Reform
June 24, 1998
Mr. Chairman, thank you for the opportunity to testify here today on the issue of civil service reform goals. In order to comply with the Truth in Testimony laws, I will note for the record that neither I, nor the Cato Institute, receive any funds from the federal government. Nor have we ever received such funds.
As a non-profit, educational institution, the Cato Institute does not, of course, endorse or oppose any specific piece of legislation. And as is always the case when our policy specialists present testimony, the views that I express here today are my own. But I’m glad to be able to share with you some of the principles that we who are strong believers in limited, constitutional government would find desirable in any overhaul of the federal civil service system.
As a general rule, those of us at Cato believe that the best government reform would be a rather dramatic reduction in the size and scope of government. In our Cato Handbook for the 105th Congress, we make the case for shutting down the Departments of Education, Commerce, Labor, Energy, Agriculture, Interior, Transportation and Veterans Affairs, and privatizing many other agencies, such as the Tennessee Valley Authority, Amtrak and the FAA.
There are plenty of people here in Washington who are content to try and make the government-owned trains run on time, and of course there’s nothing intrinsically wrong with efficiency. But we’d prefer privatizing the railroad, and getting the government out of businesses where it doesn’t belong.
Nonetheless, the federal government has legitimate core functions, and ensuring that the civil service bureaucracy carries out those functions effectively is an important public policy goal.
I was a non-career member of the Senior Executive Service for nearly eight years during the Reagan Administration, and believe strongly that political and career civil servants are both very important to the functioning of government in a constitutional republic. And I believe that a number of the reforms you are considering would highlight their distinct roles in ways that would serve the public well.
Political appointees are, by design, transient members of the federal work force. They hold their positions because they share the President’s views on public policy. They are willing and able to articulate those views to Congress and to the public on the President’s behalf, and work to see that they are implemented at the agency level insofar as law and regulation permit. Together, the President and his (or her) political appointees perform a critical function: working to translate the issues the President campaigned on into policy initiatives. When the occupant of the White House changes, they must change, too.
Career civil servants perform a very different role. They implement policy, rather than make it. They provide continuity and specialized expertise based on institutional knowledge and experience. Traditionally, at least, many spend their entire working careers in government, although that is changing.
These roles are separate, and it’s important to do all we can to keep them separate.
Most political appointees understand the temporary nature of their role quite well. But in some ways, we seem to go out of our way to tempt them to stick around. It’s altogether too common for political appointees to "career in" as an Administration is coming to an end, and there’s absolutely no reason why we should permit that. People who hold political appointments should not be allowed to compete for career positions until a new Administration has taken office. And I think it goes without saying that White House officials should no longer have a Ramspeck-like opportunity for automatic conversion to career jobs.
A factor that has long reinforced the temptation for some political appointees to stick around is the structure of the federal retirement system, and establishing a portable retirement system for them, involving individual 401K-type accounts, would be an important step.
Frankly, though, I would strongly recommend moving to a system of individually-owned retirement accounts for all federal employees, political or career. The "golden handcuffs" of overly-generous federal employee pay and benefits aren’t quite what they once were. But moving to a system of individual retirement accounts would make the choice to consider employment outside the government easier for employees who find themselves in jobs they no longer find satisfying, or where further opportunities for advancement are few. I don’t think here’s anything worse for civil servants or the public they serve than for them to be trapped in a position they hate by a compensation system that’s hard to walk away from. The American work force has become much more mobile in recent years. Few people regard working for a single employer for an entire career the "default option" any more. Our economy is much the better for it. And there’s no reason why the federal work force should be any different.
I should add that the present national discussion on the future of the Social Security system may soon overwhelm the discussion of what sort of retirement system we have for federal employees. Allowing workers to take that 12.4 percent of payroll and put it into private retirement accounts instead of the Ponzi scheme that the Social Security system really is would allow everyone, government and private sector worker alike, to accumulate personal wealth and enjoy retirement incomes that are far higher than Social Security will provide.
Let me touch briefly on several other reform opportunities worthy of note.
Limiting assignments under the Intergovernmental Personnel Act to other government agencies at the state or local level is long overdue. Allowing career civil servants to accept IPA assignments at non-governmental organizations has led to many situations where they engage in advocacy at the taxpayer’s expense. If career employees want to get into the business of policy advocacy, they should be changing employers, not office locations. The IPA was designed to give government employees the opportunity to see how things work at other levels of government, to broaden their perspective. Heavy-handed federal regulation can look quite different when you’re on the receiving end at the state or local level, for example. But the IPA should never be used to beef up the resources of a private group that’s busy trying to push public policy one way or the other.
Finally, I encourage you to curb recent trends that undermine the process of assessing performance of the federal work force. The growing popularity of so-called "pass/fail" performance appraisal systems in federal agencies threatens to make appraisals virtually meaningless. It’s important for managers to make the sometimes tough judgements about the performance of their employees on a regular basis. And it’s important for employees to know how their work is being assessed by management. There is nothing more damaging to the morale of a hard-working, high-performing employee than to receive the same performance rating as some unmotivated schlump who’s barely getting by. It’s even more devastating to see the schlump hang on to his job in a reduction in force while others who’ve worked harder and outperformed him get cut.
It is crucial that pay and retention be tied to performance appraisals. There’s got to be a reward that goes beyond a pat on the back. Granting within-grade raises automatically seriously undermines the principle of pay-for-performance. Managers should be able to make within-grade determinations without facing an arduous appeals process that extends beyond the agency administrative review system. And good performance ought to count for more than it does in RIF retention.
Mr. Chairman, I consider it a truism that we’re awfully lucky in America that we don’t get all the government we pay for. Paring back the size and scope of the federal government should be a top priority of this Congress. Where the federal establishment is properly within its constitutional bounds, the citizens of the United States deserve a civil service where performance excellence is valued and rewarded, where the compensation system is fair while enabling mobility, and where the roles of political and career federal workers are crisply defined and carefully separated.

How was the self-confession extracted? By waterboarding?
John Woodmorappe, the author of the article above, is one of the world's foremost closet homosexuals. Therefore, any opinion that he might hold on panda evolution is completely wrong, and anyone who listens to his views on panda evolution is at risk of going to Hell.

As a hypothesis/theory, something must make sense and not be invoked in an ad-hoc manner.
What this tends to mean is that if somebody talks about a designer, we have to notice a reasonable design. It is entirely possible that every pile of sticks one comes across was intentionally made in such a manner, regardless of how arbitrary it is, but we could not take this seriously.
The same holds with a deity as a designer, as we would have to see a divine purpose in a design to really believe there were a designer. Even further, if all things were designed, we would similarly need to see design across all living beings. The problem is that dysteleology really does rebut the idea. However, the idea that a divine designer designed only a few arbitrary and specific things just seems bizarre, it does not seem consistent with most models of a designer, which thus destroys models of design.
Now, could it be true that any talk of divine designers is untestable? Sure, but the theory relies upon a divine designer, and any notion of a divine designer can be logically invalidated.
Do I see Gould as begging the question when bringing up other ideas of bear design? No, he is merely pointing out what other bear designs look like, and how the variation used by a panda really does seem to be a jury-rigging of available parts. This is not invalid. As for whether the panda thumb is great, well, that is a matter of some question, and honestly I am not an expert on pandas, I would not tend to just side with one article on the matter though, and certainly that one article does not necessarily prove anything close to optimal design.
All of that being said, I really don't see the big issue with panda thumbs, nobody has brought them up and everybody thinks you are a crazy cultist, 'keet. The facts are clear, most scientists believe in the truth of evolution, have believed it for decades, and at this point, saying that they are so wrong really seems like a conspiracy theory from a group that we have almost no reason to regard as epistemically trustworthy. To somebody with a bit of knowledge on the issues, some variety of evolution seems most likely and young earth creationism can be outright rejected.

We're supposed to be communicating on here, not acting as creation ministries backup .txt server.
Very good for you, thanks for spamming my threads with off-topic posts to make this highly important point...
Other people have posted articles also in the past and it should be no different for me. Currently any time I say anything here I am insulted and attacked, so why should I really care so much about "communicating" in the manner which you would have as your particular definition in your post? I shouldn't care because it is still a form of communication of ideas, on which I am not as skilled or knowledgeable as the authors of the articles. So many insults many of you make although you've seemed to have heard the subject from one side only, so it would help you to see more of the reasons why other people think differently on this issue. If you are actually accusing me of just spamming though, shut the frivolity up.

I think the objection is that you've started a lot of threads on this one topic (or other very related topics), with many very large posted articles taken from other sources. I mean, other people will do this on occasion, but at some point it starts seeming obnoxious.

Ah, alright that makes sense. Would it be possible for people to stop throwing insults at me though? I'm sick of that as it is far worse than obnoxious.
I've tried to be civil lately. I have also offered a potential opportunity to quantitatively refute evolution. I'm mildly surprised that you don't seem very keen on the idea.

It is a parody of your recent posts
Your threads don't have input from yourself, that was my point. There isn't an idea from you, or a point, just a copied article. You cannot claim a lack of knowledge; you argue your case of intelligent design on a daily basis. I don't intend to insult or accuse the breaking of forum rules.
