Condescending Darwinists "whacking down" anti-Darwinist arguments
It’s a wearying business, arguing with Creationists. Basically, it is a game of Whack-a-Mole. They make an argument, you whack it down. They make a second, you whack it down. They make a third, you whack it down. So they make the first argument again.
-- and anti-Darwinists see arguing with Darwinists as a wearying business. Darwinists have this idea that any argument that they present is automatically an airtight refutation. For example, Darwinists think that the idea of "exaptation" (also called "co-option" or "co-optation" ) -- the notion that some parts of an irreducibly complex system had different functions before becoming part of the system -- completely refutes the idea of irreducible complexity, but exaptation is "whacked down" here and here. The absurd concept of exaptation is the Darwinists' only answer to irreducible complexity.
It would be less boring if they’d come up with a new argument once in a while, but they never do.
Questioning co-evolution is not new, but I have questioned co-evolution in ways that I have been unable to find elsewhere on the Internet. Not even the "experts" over at Panda's Thumb were able to help me.
Also, there are things called "oldies but goodies" -- an argument is not necessarily bad just because it is old. And new evidence can revive or reinvigorate old arguments -- for example, recent discoveries about the great complexity of one-celled organisms have added support to the principle of irreducible complexity.
Nowadays I just refer argumentative e-mailers to the TalkOrigins website, where any argument you are ever going to hear from a Creationist is whacked down several times over. Don’t think it’ll stop ’em, though.
You're right -- it won't stop 'em. Many of the TalkOrigins website's rebuttals of creationist arguments are very sketchy, consisting of just a few sentences. For example, the TalkOrigins' article on "obligate mutualism" does not even begin to address the questions about co-evolution that have been raised on this blog. So arguments against co-evolution were not even "whacked down" once, let alone several times over.
Creationists seem not to be aware of how central evolution is to modern biology. Without it, nothing makes sense.
Contrary to the idea that evolution is central to modern biology, I assert that it is possible to study biology without any reference to evolution theory at all (in fact, lots of students have done it), but if it makes biologists more comfortable, they can continue to use the concepts and tools of Darwinism even while believing that all or part of it is untrue.
To say to biologists: “Look, I want you to drop all this nonsense about evolution and listen to me,” is like walking into a room full of pilots and aeronautical engineers and telling them that classical aerodynamics is all hogwash.
Well, classical aerodynamics looks like hogwash. No method of scientific or engineering analysis has a lower physical relationship to reality than conformal mapping, which is used in aerodynamics. NASA says "Conformal mapping is a mathematical technique used to convert (or map) one mathematical problem and solution into another. It involves the study of complex variables ....... Many years ago, the Russian mathematician Joukowski developed a mapping function that converts a circular cylinder into a family of airfoil shapes." I previously pointed out another kind of analysis that has little or no physical relationship to reality: the use of complex-plane mathematics in the analysis of AC circuits -- the complex impedance vector is particularly devoid of physical meaning.
Biologists are of all scientists least in need of a new metaphysic. Neurophysiology aside, it is in the “hard” sciences that our epistemological underwear is showing. When physicists have to resort to explanations involving teeny strings vibrating in scrunched-up eleven-dimensional spaces a trillion trillion trillion trillionth of an inch across, or cosmologists try to tell us that entire universes are proliferating every nanosecond like bacteria in a petri dish, there is a case to be made for a metaphysical overhaul. Not that work in these fields has come to a baffled dead stop, as George seems to imply ........ Biology, by contrast, really has no outstanding epistemological problems.
Ahem. Biology has no epistemological problems? Biologists don't even have a hypothesis -- let alone a theory -- for explaining the origin of life.
Why is the proportion of scientists willing to accept it [creationism] still stuck below (well below, as best I can estimate) one percent?
Wrong. A recent poll of physicians -- who are well-trained in the biological sciences -- shows that a large percentage of them are skeptical of Darwinism.
=================================================
Darwinists' disdain for their opponents extends well beyond biology and into other fields, such as law. For example, in response to my literal interpretation of Rule 12 of the Federal Rules of Civil Procedure, "Dan," a friend of Ed Brayton who teaches constitutional law, responded with nothing but invective and Ed banned me permanently from his blog, "Dispatches from the Culture Wars." The Darwinists think that in any debate, they are the only ones who are informed and who can think logically. Everyone else is stupid and ignorant.

This is an outstanding explanation of what goes on here on this blog. Larry(?) ignores all proof of the poverty of his arguments and repeats them over and over.

A better analogy would be walking into the same room and telling them that no machine can be made to fly.

This is a good example of the first paragraph cited. This statement has repeatedly been shown to be false on this blog yet Larry(?) acts as if it is a new and valid statement.

The link that you give here does not show "nothing but invective". You seem to believe that rational arguments that go against your fantasies are "nothing but invective" To see "nothing but invective" you will have to examine some of your own posts.

Not necessarily, but it is what we have observed on your blog.

Whoever these "Darwinists" are, they obviously don't have a full understanding of modern evolutionary theory. Exaptation, which has been observed experimentally, in the wild, and in simulation, is not the only argument against irreducible complexity. It is part of an entire suite of arguments, sometimes called "scaffolding." In reality, irreducible complexity at best shows that simple stepwise addition can't lead to a certain structure - but modern evolutionary theory doesn't rely solely on simple stepwise addition.
>>>Questioning co-evolution is not new, but I have questioned co-evolution in ways that I have been unable to find elsewhere on the Internet. Not even the "experts" over at Panda's Thumb were able to help me.<<<
Well, gee, if it's not on the internet, the argument must never have been made. Newsflash - the internet hasn't been widely in use for all that long. There are entire books for the general public about co-evolution - it's possible, just possible, that the answers to your objections are dealt with there. The fact is, your objections have been dealt with previously - it's a creationist talking point, albeit not very popular because "Co-evolution proves evolution wrong" generally doesn't work very well as a meme, and the standard creationist foot soldier has trouble explaining it to the masses.
>>>Also, there are things called "oldies but goodies" -- an argument is not necessarily bad just because it is old. And new evidence can revive or reinvigorate old arguments -- for example, recent discoveries about the great complexity of one-celled organisms have added support to the principle of irreducible complexity.<<<
Same evidence, different structure, same argument. "Ooh, it's small and complex" is still the same argument as "It's complex."
>>>You're right -- it won't stop 'em. Many of the TalkOrigins website's rebuttals of creationist arguments are very sketchy, consisting of just a few sentences.

Actually, I sort of agree with you here. Many of the less often used arguments are given much shorter treatment than they should be given. You state three basic objections. The first, the two mutations must simultaneously arise, is dealt with (poorly) in the TalkOrigins page. The answer is that the original features were present prior to the co-evolutionary link developing, at least in one of the species. It may have been neutral, beneficial for a related reason, beneficial for an unrelated reason, or even slightly deleterious (especially if it's linked to a eneficial trait). The other species has or eventually develops a feature that can take advantage of the first species feature. The first species feature gets slightly modified and better adapts to the second species feature, giving it an advantage over competing species or embers of it's own species, and the two species now have a weak co-evolutionary link, which strengthens as additional modifications accumulate. Your other objections are basically extensions of the first objection - separation of time and space and individuals v. populations. As long as the original species didn't require the presence of the corresponding feature to survive with their original feature, the populations can eventually meet and start the co-evolutionary link. As far as the mutation spreading from individuals to the general population, that's basic population genetics. As long as the individual steps aren't too drastic, the mutations wil be able to propagate through the population. Co-evolution is not a sudden change, it's a series of incremental steps over a long period of time.

Without evolution, biology is just a collection of facts. Sure, you can memorize facts, but without an underlying theory, the facts don't suggest anything that hasn't already been demonstrated. Evolution gives biologists a framework within which to work. Without it, or something like it, the experiments would have to be done at random. Creationism (including intellegent design) doesn't provide any such framework - in fact, it attempts to destroy any framework from even being considered.

And you still are wrong about the physical meaning of complex vectors in AC analysis. The impedance vector, like all vectors, is actually two related physical measurements combined into a single number. The complex impedance vector is A) the ratio of peak voltage to peak current, and B) the time delay (referenced to the frequency) between peak voltage and peak current. Complex-plane mathematics is simply a form of trigonometry. Since AC-circuits are sinusoidal, using trigonometry is the proper math.
>>>Ahem. Biology has no epistemological problems? Biologists don't even have a hypothesis -- let alone a theory -- for explaining the origin of life.<<<
Actually, they have several hypotheses, supported by experimental data. The problem is that there is not enough data to be conclusive. Of course, this is not a problem for evolution itself, as evolution simply requires the existence of imperfect replicators with limited resources.
>>>Wrong. A recent poll of physicians -- who are well-trained in the biological sciences -- shows that a large percentage of them are skeptical of Darwinism.<<<
Sadly, physicians aren't generally well-trained in biological sciences. They are well-trained in anatomy and physiology, but much of that training is memorization or looking up of facts. A lot of the theory is left out. Most physicians are more akin to technicians than scientists. That is not to denigrate physicians or technicians - the jobs are just as important, but they are different. Just as I would not trust an electrician to properly design the electrical systems for a 2.5 million square foot automotive manufacturing plant, I would not trust myself (an electrical engineer) to properly install that system. Most pysicians aren't scientists, and simply aren't trained as scientists.

Yes, you have used up your allotted questions but in honor of the service you do by filling in for me on weekends, I will answer.
Of course I could just answer "yes", which technically would be the most direct answer to your question, but that would be unfair. I will instead break your question into parts to make the answers more meaningful:

I hope this casts a great white light on the situation. It is certainly more illuminating than any answer that you have ever received from Larry(?).

>>>>>>Yes. An excellent example is Sickle Cell disease. This is actually quite harmful, but it is not as bad as malaria, to which it confers resistance. In areas where malaria is endemic, it thus is an adaptive advantage, and it's in those areas that it is common.<<<<<
Sickle cell disease is pretty bad -- probably as bad as malaria. Here are some statistics for sickle-cell disease in the USA, and they look pretty bad for the victims:
Frequency:
In the US: Incidence of the homozygous state among black newborns is about 0.8%.
Approximately 8% of blacks carry the mutated gene.
Mortality/Morbidity: Data from Quinn et al (2004) suggest improvement in mortality rates for patients with sickle cell disease over the past 30 years. Recent information suggests 85% survival to age 18 years. This study tracked 700 children for 18 years.
Earlier data reported that among patients with sickle cell disease, approximately 50% do not survive beyond age 20 years, and most do not survive to age 50 years.
Race: The highest incidence is in those of African descent. -- from eMedicine article, "Anemia, Sickle Cell"
Actually, the benefit is that the carriers of the sickle-cell disease as well as the victims apparently have a resistance to malaria. The Wikipedia article on sickle-cell disease says, "The sufferers of the illness have a reduced life span. It is believed that carriers (sickle cell trait) are relatively resistant to malaria. Since the gene is incompletely recessive, carriers have a few sickle red blood cells at all times, not enough to cause symptoms, but enough to give resistance to malaria."
I see no reason why the incidence of sickle-cell disease should diminish where resistance to malaria is of no particular advantage to the carriers. Sickle-cell disease is transmitted by carriers who are relatively large in number compared to the victims (8% vs. 0.8% of US blacks), so the disease's sometimes fatal effect on the victims at an early age should not be a major factor in the transmissibility of the disease.

>>>>>Same evidence, different structure, same argument. "Ooh, it's small and complex" is still the same argument as "It's complex."<<<<<
But it means that the principle of exaptation must be demonstrated all over again on a different set of features -- and exaptation was not even demonstrated the first time.
>>>>>The answer is that the original features were present prior to the co-evolutionary link developing, at least in one of the species.<<<<<<
But where a co-dependent feature offers no independent advantage that would benefit from natural selection, how could that feature evolve independently of the corresponding feature in the other organism? Examples of such features are the colors and scents of flowers and the abilities of pollinators to sense those colors and scents. I thought that natural selection was supposed to be one of the cornerstones of Darwinism, so how can there be evolution without natural selection?
The idea of co-evolution presents the following problems and issues:
(1) Unlike the kind of evolution which is adaptation to widespread fixed physical features of the environment, e.g., land, water, and air, in co-evolution there is often nothing to adapt to because the co-dependent trait is likely to be initially absent in the other organism.
(2) A co-dependent trait could be non-viable or deleterious in the absence of the corresponding trait in the other organism. When this is true of corresponding traits in both organisms, co-evolution is virtually impossible.
(3) Even where the traits in the two organisms could develop independently, the traits often give no benefit in natural selection when developing independently. Examples are the colors and scents of flowers and the abilities of pollinators to sense those colors and scents.
(4) Often, co-dependent organisms can interact only in large numbers -- e.g., a bee visits many flowers and a flower is visited by many bees. Hence, large numbers of both kinds of organisms with corresponding traits may have to appear suddenly at the same place at the same time.
(5) In cases of co-evolution that are supposed to consist of a series of incremental steps in both organisms, e.g., the co-evolution of deep flowers and long-nosed insects, the evolution of one of the organisms must stop at each step while the evolution of the other organism catches up. This would greatly slow down an evolutionary process which may have just a few million years to take place.
(6) Often a co-dependent relationship consists of an "irreducibly complex" combination of pairs of traits rather than a single pair of traits. This compounds the problems presented by co-evolution and irreducible complexity.
>>>>>>Without evolution, biology is just a collection of facts. Sure, you can memorize facts, but without an underlying theory, the facts don't suggest anything that hasn't already been demonstrated.<<<<<<
I assert that the notion that evolution was driven solely by natural genetic variation and natural selection is of no use anywhere in the biological sciences.
>>>>>And you still are wrong about the physical meaning of complex vectors in AC analysis. The impedance vector, like all vectors, is actually two related physical measurements combined into a single number. <<<<<<
You still don't get it. Sure, the impedance vector gives the phase angle and the relative magnitudes (not the ratio, since this is a comparison of unlike things, voltage and current) of the peak voltage and peak current, but there is no intuitive connection between the impedance vector and the inductance, capacitance, DC resistance, and AC frequency. I recommend that you go back and read the article on AC circuit analysis again and try to understand it this time.

it isn't daft -- it actually makes pretty good sense. An incomplete, functionless system may actually be deleterious to the organism, and even if not deleterious, the incomplete, functionless system would provide no advantage in natural selection.

I think that Behe's redefinition addresses the following issues:
(1)-- findings that some systems that were previously thought to be irreducibly complex can function with a component missing.
(2) -- findings that some components of irreducible systems might have come ready-made because those components previously had other functions outside the system (this change in function is called exaptation, co-option, or co-optation).
So Behe's new definition says that a barrier to evolution could occur at any stage in the hypothetical evolutionary development of the system.
In his article titled "In Defense of the Irreducibility of the Blood Clotting Cascade:
Response to Russell Doolittle, Ken Miller and Keith Robison", Behe gave some reasons for changing his definition of irreducible complexity.
< it isn't daft -- it actually makes pretty good sense. An incomplete, functionless system may actually be deleterious to the organism <

Not everything that evolves necessarily is advantageous. Nobody claimed otherwise.

In other words, he found that the "irreducible complexity" of some systems was reducible.

So irreducible complexity has been demolished completely and yet Behe wants to say that it is still valid but he doesn't understand why.
Incidentally, why have you failed to "demolish" my questions? I see that you are dodging as usual.

Without an advantage, there is no natural selection, which is supposed to be one of the cornerstones -- if not the cornerstone -- of Darwinism.
Also, the ability of "genetic drift" to produce significant change is questionable. Many species appear suddenly in the fossil record and then continue virtually unchanged for millions of years until the present day or until they became extinct.
>>>>>In other words, he found that the "irreducible complexity" of some systems was reducible.<<<<<<
-- reducible to a slightly simpler system which itself might be irreducible. So Behe made some mistakes. Darwinists make mistakes too. Making mistakes does not make something unscientific.

Wrong. These findings could just be the exceptions that prove the rule.
And even the availability of all the components of an irreducible system is not enough. You can take all the parts of a car, put them in a bag, shake the bag well, and then pour out the contents, but you will not get an assembled car.
What I like about ID is that unlike Darwinism it does not make claims that are beyond what can be demonstrated by science.
>>>>>>Incidentally, why have you failed to "demolish" my questions? I see that you are dodging as usual.<<<<<<<
OK, I just demolished some of them. And as I have said umpteen times, I am not obligated to respond to any of the comments posted on this blog. On Panda's Thumb, for example, the bloggers rarely respond to the comments.
> Without an advantage, there is no natural selection, which is supposed to be one of the cornerstones -- if not the cornerstone -- of Darwinism.<
There may be all sorts of variations that arise that have no immediate benefit. Natural selection requires that there be something from which to select.
> Many species appear suddenly in the fossil record <
There are vast sections of the fossil record that are absent for geological reasons.

And then again it might not.

If the mistake is in the core assumption, it demolishes it.

You don't seem to know the meaning of an "exception that proves the rule". Rather than trying to get it through your neutron star skull, I would suggest that you look up the term on the Internet. Proving something false is never evidence that it is true.

This shows your lack of understanding of evolution. How can you criticize something that you don't understand in the least?
> What I like about ID is that unlike Darwinism it does not make claims that are beyond what can be demonstrated by science. <
No. It makes claims whose falsity can be demonstrated by science.

No. You just demonstrated your lack of understanding.

You do if you pretend that you have taken on all comers as you hypocritically often do. You have selected the easiest questions to answer and then failed miserably in your attempts to answer them. Let's see you "demolish" some next time.

>>>>>>A recent poll of physicians -- who are well-trained in the biological sciences...
You are kidding, right? I teach medical students. It has been a long time since med students received advanced general training in the biological sciences.<<<<<<<
It was the closest I could come to a recent formal poll of professionals who are not pig-ignorant about general biology. What we need is a recent formal poll of real biologists.
Genetics is an extremely important topic in the evolution controversy, and I suspect that physicians are now being well trained in genetics because genetic testing, genetic counseling, and even gene therapy (still in the early stages) are now important medical fields.
The poll shows that surprisingly high percentages of physicians are skeptical of Darwinism, and I don't think that those high percentages can be explained away by arguing that the physicians are not well trained in general biology.

They get training in the genetics of human disease. They do not receive advanced training in molecular biology or genomics.<<<<<<<
In your desperation to explain away physicians' widespread skepticism about Darwinism, you are really getting nitpicking about differences in training in genetics.
If, as you claim, the education of biologists uniquely qualifies them to give opinions about the evolution controversy, then why aren't we polling biologists' opinions about the controversy?

Your "guess"? I am not interested in guesses -- I want to know the facts!
Who are "the people who conduct such polls"? Anyone can sponsor one of these opinion polls.
>>>>>>Among biologists, there is no controversy. Among biologists, there is no controversy.<<<<<<<
I am not interested in your anecdotal stories about what biologists think about the controversy. I want the numbers! I thought that you Darwinists were supposed to be great big grownup scientific people who were interested in scientific results! Now you are trying to tell me that biologists' opinions about evolution are not testable?
>>>Anyone can sponsor one of these opinion polls.<<<
Indeed. What's stopping you, Larry?
