Pseudoscience is a scientific-sounding argument which in fact has no scientific validity whatsoever. This type of argument is based on the fact that the average layperson knows so little about science that he or she is liable to judge a scientific argument solely on its style and presentation (eg- "does it sound scientific?", or "does it incorporate scientific-sounding terms?") for lack of any other method of judging its validity.
Suggested Tactics
This type of creationist argument is difficult for most people to defend against, unless they are fairly knowledgeable about science (that's why it's so popular with creationists- they may not know anything about science, but they're gambling that you don't either). In my case, I simply call upon my knowledge of certain basic scientific principles that I learned in university, but I can't instruct everyone to do this, since not everyone has a technical background.
Therefore, it's difficult for me to recommand tactics for laypeople to counteract this sort of argument, but we should keep in mind that creationist pseudoscience arguments are almost never generated out of the mind of the creationist himself. They all tend to come from the same widely distributed pool of creationist literature, which is one of the reasons that creationists all over the world tend to spout the same pseudoscience arguments. I can offer the following suggestions:
Remember that if your opponent has no direct knowledge of the science involved, and is merely claiming truth because "I read it somewhere", this constitutes a fallacious appeal to authority. Point this out to him. One should always be able to explain the logic and science behind one's argument rather than simply making vague reference to an anonymous source.
Since these arguments are actually second hand arguments, demand to see the original source for his claim. When you see the source, check the credentials of the author. If they aren't fraudulent, check up on the university where the author got his degree. Odds are that the degree is either honorary, or it comes from a cheap diploma mill (or worse yet, one of the many church-run schools set up expressly for the purpose of handing out degrees to creationists). If you don't have the resources to check up on universities, try looking up the Talk.Origins website at www.talkorigins.org, which maintains a list of discredited creationist "experts" and their bogus credentials.
Examples follow:
"Occam's Razor is a scientific principle which says that when faced with two theories, we should always choose the simplest theory. Evolution theory requires billions of years of chemical reactions, environmental effects, and genetic mutations. Creation theory simply says "God did it". Creation theory is obviously simpler, therefore Occam's Razor demands that we must select Creation theory on scientific grounds."
This is perhaps the single most moronic creationist idea I've ever heard (it's also been used to "prove" the existence of God, by arguing that the concept of God is much simpler than the study of science). It's a classic example of creationist pseudoscience. They learn the term "Occam's Razor" and they learn just enough about its definition to abuse it, but they make no effort whatsoever to learn its true meaning.
"Choose the simplest theory" is an oversimplification of the concept of Occam's Razor. The term is named after the 14th century philosopher and theologian William of Occam. It might strike some as strange that a scientific principle might have come from a theologian, but good scientists do not practice appeals to authority or ad hominem attacks. If an idea makes sense, it doesn't matter who it came from, and the universal acceptance of Occam's Razor is a perfect example of that philosophy.
In any case, he argued that we should never "multiply entities unnecessarily". In other words, cut out extraneous terms from an equation. He used that principle (which is really just an argument against redundancy) to show that it was impossible to deduce God's existence through reason alone, so one would have to take it purely on faith. The irony is that a theologian realized that there was no logical basis for God's existence more than 600 years ago but modern fundamentalists still can't figure it out, and actually use his name to "prove" the exact opposite of what he himself argued!
For those who cannot appreciate the simplicity of Occam's Razor in its original form, Isaac Newton restated it thusly: "We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances." In plain English, when faced with two scientific theories which make the same predictions, choose the simpler theory. Or, as Stephen Hawking put it: "Cut out all the features of the theory which cannot be observed." (taken from A Brief History of Time).
Like all scientific principles, Occam's Razor is accepted not because William of Occam said it, but because it makes sense. You don't need to appeal to authority or take its validity on faith. If you are faced with two competing theories between which you have no other method of deciding, is it not obvious that the theory containing extra or unverifiable terms must therefore contain redundancies? The fact that the simpler theory can accomplish the same descriptive and predictive feats while utilizing fewer terms and not relying on unverifiable or unobservable phenomena is evidence of superiority.
Consider the analogy of two mechanical devices for making widgets. Both perform exactly the same function. In repeated, exhaustive tests, both are shown to produce exactly the same quality of widget, at the same rate, with the same raw materials. Both produce the same amount of waste. Both consume the same amount of electrical power. They cost the same. In other words, their performance is identical in every measurable way. The only noticeable difference is that device #1 is much simpler than device #2. It contains fewer components and mechanisms, and its operating principle is therefore simpler. Which one would you choose?
Suppose the salesman for device #2 is quite upset that you are leaning toward device #1, and he promises to do better. The next day, he returns with a new device (we'll call it device #3) which is completely sealed in black plastic (the classic "black box"). He says it's the latest, most advanced widget-making machine in the world. You feed it electricity and raw materials, and it spits out widgets. Its performance is no different from device #1 and device #2, but it is not user servicable. You can't see inside to figure out how it works, and the salesman refuses to let you see diagrams or schematics, ostensibly because the operation of the machine is beyond both your intellectual capacity and his. The salesman argues that device #3 is actually simpler than both device #1 and #2 because it has just one component: the black box. Does this make sense to you? Again, which device would you choose?
Occam's Razor is merely a name given to a logical and intuitively obvious thought process of eliminating redundancies. It cannot be used to choose between competing theories whose predictions are vastly different, any more than the simplicity of a drill press can be used to prove that it's superior to a fighter plane. Now that we are equipped with an understanding of the reasoning behind Occam's Razor, we can list some of the reasons that it cannot be used to support either creationism or the existence of God:
The use of Occam's Razor to "prove" the existence of God or the validity of Biblical literalism is a classic example of creationist pseudoscience, because it is so emblematic of their method: take a real principle and grossly misinterpret it to mean the exact opposite of what it truly means.
"The second law of thermodynamics makes evolution impossible. It states that complexity cannot be spontaneously created, so it is impossible for natural processes to create a complex organism from a simple organism!"
This is one of the oldest, and most popular creationist pseudoscience arguments. It's been kicking around for more than a century, thanks to general public ignorance of thermodynamics. In fact, it's wrong on so many levels that it's hard to know where to start! Perhaps we should start at the beginning, with the definition of the second law of thermodynamics. According to my engineering thermodynamics textbook, the second law of thermodynamics has two basic postulates:
That's a lot different from "complexity cannot be spontaneously created", isn't it? Big surprise- creationists don't know anything about thermodynamics. Now that we've established their bizarre misconception about the second law of thermodynamics, we should try to understand what strange mental contortions were necessary to go from "the entropy of a closed system cannot decrease" to "complexity cannot be spontaneously created."
Upon further questioning, creationists invariably reveal the following beliefs about the second law:
These three beliefs are all completely wrong, and they all indicate a frightening ignorance of scientific principles. Let us examine each belief separately:
This argument has been so thoroughly disproven, so many times in so many ways, that it's almost comical when people keep bringing it up. They might as well just tattoo their foreheads with the words "scientific ignoramus."
"By taking a random mixture of elements and analysing the probability of elements randomly forming into the correct combinations and orientations to make a simple amino acid, I can show that it is probabilistically impossible for the simplest amino acid to form, never mind the first living cell. Therefore, a Creator must have formed the first organisms, if not all of them."
This argument is invalid for the following reasons:
I should also note that this argument is generally coupled with the fallacious reasoning that "anything we don't understand is proof of divine intervention." Poorly understood phenomena are not invalidations of science- they are opportunities for scientific investigation. If we treat every gap in our understanding as proof of divine intervention, we would be no better than the tribal primitives who attributed divine intervention to everything from solar eclipses to rain. Visit the Probability page if you want to know more.
"Some older species fossils can be found on top of newer fossils. This inconsistency in your so-called 'progressionism' proves that creation theory is correct, since it means that all species were created at the same time."
More bad science, since this only occurs with animal remains that are on the surface. What happens is that severe erosion or a geological upheaval can occasionally expose strata bearing fossils, and of course, when Skippy the Dog runs away and dies near these old fossils, the "Young Earth Creationist" crowd immediately interprets this as disproof of the entire fossil record, the entire field of geology, the age of the Earth, etc.
As usual, their argument is based on ignorance of proper scientific method. This evidence would be disproof of the fossil record if it was impossible to rationalize its existence with that record. However, that is simply not the case. Geologists can examine patterns in the rock to determine whether a region is old or new, cross-cut, the result of upheaval, etc. It is the creationists who will look at a region, assume its age without using proper methodology, and then use fossil findings in that region to "disprove" geology and evolution theory.
"Evolution can explain changes in a species, but where does a whole new species come from? Speciation is the downfall of Evolution Theory!"
This is another case of creationists projecting their own pseudoscientific attitudes onto evolution theory. In this case, they are predisposed to believe that the creation of a species is a sudden, dramatic event at some fixed moment in time. One moment there's species A, and then the next moment there's species B. Much as God created Man from dust, and Eve from Adam's rib, they imagine that "evolutionists" describe evolution creating a man directly from an ape. But evolution theory does not work that way.
Speciation is not a sudden, miraculous transformation from one species to another. The way creationists envision evolution theory, a pregnant female ape went into labour one day and a human being popped out! It is a gross understatement to say that this is a misrepresentation of the truth. In reality, evolution theory merely proposes that a great many small changes eventually caused an animal population to become intersterile with its ancestors.
Of course, this would mean that there should be fossil evidence of various intermediate stages between successful species, and there is. Naturally, creationists explain all of the evidence away by pointing the finger at their favourite whipping boy: the global conspiracy of evil scientists, who work tirelessly to cover up the truth and fabricate false evidence. These people watch "X-Files" too damned much.
"I know we've observed micro-evolution, but what about macro-evolution? There is no evidence for macro-evolution!"
The creationist invention of the terms "macroevolution" and "microevolution" is a good example of how they try to mutilate the terms of science to their own advantage. Biologists do not differentiate between micro-evolution and macro-evolution, any more than mathematicians differentiate between micro-addition and macro-addition.
Their argument that there is no evidence for "macroevolution" is ridiculous because "macroevolution" is simply the result of adding a lot of "microevolution" together, and "microevolution" is, by their own admission, completely supported by various forms of evidence.
The other problem for this argument is that there actually is evidence to directly support what they describe as "macroevolution", and it's called "the fossil record". It's evidence because it is consistent with prediction. Of course, that's not enough for the creationists- they demand direct observation of massive evolutionary change in living animals, even though they know that we would have to observe living animals for millions of years in order to obtain the evidence they seek. Can you see the problem with this demand? It's pretty obvious- they are deliberately asking for a form of evidence which is impossible to obtain (millions of years of direct observation), and ignoring a form of evidence (the fossil record) which is relatively easy to obtain.
The universe operates on tiny processes, affecting tiny particles, which add up in tremendous numbers to cause large changes. If someone is going to claim that a slow, steady process cannot create large-scale changes given sufficient time, he had better provide some evidence and reasoning, rather than simply stating it as a fact and demanding impossible forms of evidence to disprove it. Are we to assume that all gradual processes eventually hit "brick walls" and stop, for mysterious and unknown reasons?
Do we question tectonic plate theory on the basis that we've observed small-scale tectonic plate movement but not large-scale tectonic plate movement? Do we insist that no one should believe in tectonic plate theory until we've been able to observe it for millions of years, so we can see long-distance movements firsthand? Do we deny the possibility of large-scale rock erosion because we've only seen small scale rock erosion? Why would a gradual process like tectonic plate movement, rock erosion, or evolution suddenly stop after an arbitrary length of time? What would make it stop? Why make this ridiculous distinction between "micro-evolution" and "macro-evolution?" Where is the line drawn between the two? What causes the barrier? These are questions that the creationists don't attempt to ask or answer, because like O.J. Simpson's defense lawyers, they're not serious about uncovering the truth. They just want to create "reasonable doubt" in the minds of a gullible audience.
The "microevolution vs macroevolution" argument is an example of creationists projecting their own mentality onto evolution, and then attacking the resulting strawman, ironically, for the very aspects that come from creationism. Creationism describes separate and distinct species: "each according to its kind". Creationists therefore make the same assumption: species are separate, indivisible, and disconnected. When they project this mentality onto evolution, they run into an obvious problem: there is no way for the process of evolution to "jump" over the invisible "barrier" between species. The problem is that they are assuming that this barrier exists! The terms "microevolution" and "macroevolution" are not found in biology; they are creationist inventions. Gradual changes eventually add up, and can turn one species into two, or they can cause a species to change so much that it becomes a distinct species from its predecessors.
As a thought experiment, consider human beings. It is generally assumed that any male/female pair of healthy human beings can produce children. But biological reproduction is a complex process, and it requires great genetic commonality. We know that two modern human beings can produce children, but what about a modern woman and a man from ten thousand years ago? What about a modern woman and a man from fifty thousand years ago? Is there still enough genetic commonality? Species are not delineated by distinct, clear boundaries. Rather, they are defined by intersterility and overt physical characteristics, and there is no "barrier" between species for the process of evolution to hurdle. |
I can't remember and am too lazy to check. Have you always on these threads said Archaeopteryx is a dinosaur? So few of your brethren do. And how can there be any dispute at all over whether something is a dinosaur or a bird for gosh sakes?
We are concerned with facts here. What Darwin said or did not say is irrelevant. If he gave proof of it that would be relevant, but of course he did not. He never gave proof of anything.
The point was made that to account for some evolutionary changes in hemoglobin, one requires about 120 amino acid substitutions...as individual events, as though it is necessary to get one of them done and spread throughout the whole population before you could start processing the next one..
First of all, the above has nothing to do with the kind of co-evolution we were speaking of. We were talking of different genes, different characteristics, arising. This tells of just one gene, one faculty. However, let me just say this regarding the above. It is hogwash. Here's why. Yes, the change does not need to take place in one person at one time. However, because mutations are rare (else a species would dissappear in no time at all) the first mutation would have to spread itself to other individuals in the species. The problem with spreading the mutation is genetics. Each time it spreads, the mutation only has one chance in two to survive (and no, this has nothing to do with survival of the fittest and all that nonsense). So for a mutation to spread would be pretty difficult (that's one of the reasons for evos developing punk-eek). While you could be having other mutations going on in other individuals, this would not add to the mutations in the group with the other mutation because of the laws of genetics. Even if these two sets of mutatated genes were two be resident one in the father and one in the mother of a child - the child would only inherit one of the genes because of the laws of genetics. The article is therefore absolute hogwash.
BTW - the above is one of the many things in which Darwin has been thoroughly refuted. He thought that the differences of the parents "melded" in the progeny.
How do you know that macro-evolution happens? Have you seen it? Do you have proof of it? Or is it some sort of mythical atheistic belief?

This makes having more than one experiment going on a piece of cake.
There are all kinds of mutations in all kinds of genes going around in a sexual species at any given time. Your model is still too serial. There are probably other problems because my eyes glaze over when I read your dense blue paragraphs. Are you allowing for recessive genes? You have more genes to give your children than you may be expressing.
A population is a cloud of individual genomes about a central average. Selection can move the average if things change. Think of that cloud as a sphere. The rightmost 40 percent gets lopped off. Now the center of mass has "moved."
BTW - the above is one of the many things in which Darwin has been thoroughly refuted. He thought that the differences of the parents "melded" in the progeny.Darwin wrote before Mendel. Anyway, the differences of the parents do meld in the progeny, but only overall, not in the micro traits.
Evolution, which has real information content, tells us that they did not.
I asked you to back it up in post 771. Now you refuse and start playing games about I asked you first and such nonsense. Clearly you are unable to back up your claims that we have proof that dinosaurs did not have mammary glands, warm blood and were more intelligent than mankind. You just make bald assertions and throw dirt on the wall hoping no one will call you on it. Well I am calling you on it Vade. Give the proof.
Want to see something new, not just the same old same old? Well, I'll show you anyway. BMCDA found some nice new web pages on ring species.
Don't ask me to read them to you.
What does evolution say about the possibility of teats on a dinosaur and why does it say it? After all, you know that what it says is wrong, so you must know what it says and why it says it.When you say this
You just make bald assertions and throw dirt on the wall hoping no one will call you on it. Well I am calling you on it Vade. Give the proof.does that mean, "OK, I give up? I can't imagine what evolution says on the subject or why it would say it?"
Sure you want to do that? How can you put down evolution if you have no idea how it works?
There's a line of evolutionary reasoning which says "No" to mammaries on dinosaurs.
I say this even though I've often shown you a figure of reptilian skulls almost morphing into early mammal skulls, so obvious is the relationship.
Big, big hint: None of those reptiles were dinosaurs.
Yet this camera works better than any camera we can make! The bat's sonar is also better than any we can make also. To call these organs "wrongly made" when we do not even understand them and cannot make anything better is totally wrong. When you do not know the reasons, when you cannot do better, you cannot criticize the work of another.
I guess you call the above "proof" of evolution? Note that you do not give us any pictures and I bet you do not even have the vaguest idea what this species is. Do note however that they are still all called by the same generic name.
BTW - what you posted is all the text in the article! Some proof! You just pick a title you like and call it proof.
Mollusks get out of their shells, often make different shells in a lifetime. They are a form of housing. Do different species of humans live in one story houses than in two story houses?
Your little shells are just one more example of the phoniness of the so-called "science" of paleontology.
Are you saying that a woman with long hair is a different species than one with short hair? That a woman with the hair tied up at the top is a different species than one who lets her hair just fall? Mollusks and other shelled animals (tortoises for example) can get out of their shells. The shell says absolutely nothing about the animal inside except perhaps as to its relative size (but then there are small mollusks and they change and make new shells as they grow up).
Ah! Semantics! I can still find the thread in which you argued that because a platypus is called a duckbill, the bill must be a duck's bill.
It feels so funny, realizing you're not going to read this for a long time yet. I said it on another thread long ago, but what the heck.
Watching you read down a thread, I can imagine I see your lips moving.
I'm bullying again! (Sob!) Stop me!
If I said this

It is the evolutionists which create arbitrariness. Heck in one of the posts here they call changing the sex call of an organism the creation of a new species! Guess Chinese are a different species than English, they talk a different language! I gave you non-arbitrary distinctions and explained the reasons for them in a post to Junior a few posts above this one. The distinctions for macro-evolution are: in taxonomy - a new genus, in terms of genetics a set of new genes, in terms of phenotype - new faculties and increased complexity.
The distribution of this species is from British Columbia in Canada, through Washington, Oregon, California and into Baja California of Mexico. Presently, seven subspecies are recognized,
They are not even species and you call this macro-evolution? Please!
As to the guinea pigs, some mammals can and do manufacture vitamin c, that's why I do not consider this having to do with descent. Same with the chimp hemoglobin. All scientists agree that man and monkeys split off somewhere a long time ago so if both man and chimp have it, then the other apes should have it too and this does not seem to be the case from what you say. The cheetah is interesting, had not heard about it and it is certainly curious.
Now as to your point, yes it could show descent, however, there are so many curiosities in living things which cannot be accounted by descent - the platypus, the bat, and many others that it seems to me that what we have is a designer who used some parts of his "building blocks" in different places with as far as evolutionary theory goes no sense at all (although I am sure there was good reason since the species in which this happened work well). I don't expect you to change your mind over the above, however, it is another way to think about these curiosities.
