Science Research Proves Evolution Hoax : The Conflagration, When Parallel Universes Merge

Bruce D. McKay, Elijah Format ISBN Price This Book is Coming Soon Paperback (6x9) 142089353X $

About the Book

Packed with eye-opening facts that expose evolution as a faked ideology, "the great apostasy" was set up using underground couriers and agents of pre-Nazi Germany, who plotted to reprogram the minds of the entire world! The plan fitted many fakes of Haeckel and others, and major frauds such as the Piltdown Man, in an international undertaking. Leading socialists in England and Germany were used to rig the string-like controls of Darwin, Huxley, and others, who functioned as living puppets. Their tricks and discoveries managed to outwit the leading scientific minds of America and England; even the Royal Society members were deceived. All were deceived by what the Nations did - and many today are still ensnared in the utterly deceptive, faked scientific ideology of evolution.

About the Author

Bruce D. McKay is an biological epistemologist. He graduated from Florida State University in Tallahassee, FL, (1967). Ranked third in the entering class in the biological sciences, on entrance exams at FSU. His gifted intellect surfaced in 1952, after he died and was "taken up."(Wis. 4:14). He saw The Tree of Life, the River of Life, the Promised Land, and “millions of souls under the altar” who died rather than forsake the word of God, exactly as in Rev. 6. After pulling his wing around him the Lord said, "They know that I am not willing than any man should perish." Then McKay "freely volunteered" to be sent back! He says, “I wanted to tell everyone, Heaven is a very real place!”

I have to agree, from the description this book is like no other I have ever seen.

Response: No, our definition of evolution is "change in the genetic characteristics of a population over time". (Quoting the Introductory FAQ). Evolution also refers to the "common descent of living organisms from shared ancestors".

Evolution is not only adaptation, and adaptation does not maximize survivabilty.

Your own DNA is different from that of your parents. Every new human individual introduces roughly 100 new mutations or thereabouts. Most of these mutations have no effect; but a few will make some kind of difference. This means there is a continual source of new variation not present in original DNA.

For dogs, new breeds are obtained by a combination of three methods ( offsite link):

  • limiting the ancestral variety to emphasize desired traits,
  • cross breeding to bring traits from one breed into another,
  • and breeding from dogs that have some new feature from a new mutation.
You've ignored the last part entirely, but it is a significant contributory factor for many breeds. The claim that all the variety is in the original pair is trivially false. We see new mutations and new genetic information in dogs and all other organisms. It is a simple part of how life on Earth works.

Evolution is not chance. What drives evolution of well adapted organisms is selection, which is the very opposite of chance.

Response: We get feedback of all kinds; some from Christians who resent evolution; some from unbelievers who resent Christians; and many from folks who are happy to engage the subject matter without any particular resentment. You'll never get everyone to behave with maturity. We get plenty of mockery directed at the archive as well, which causes us more amusement than pain. A thick skin helps. Relax; and be welcome. We appreciate your feedback.

The talkorigins team itself includes Christians, atheists, agnostics, theists, and a couple of other self-descriptions. No-one bothers to keep track; and the approach of the archive is generally accepting of all kinds of religious belief.

Our focus is on the empirical matters that are the purview of science. Many Christians have religious beliefs that have been shown false by straightforward science. The information we supply of course conflicts with their beliefs; but that can't be helped. Many other Christians believe God ordained and established all the processes of the natural world, evolution included, and see no conflict between their faith and the discoveries of science. We have no official position on that.

You've identified exactly what is wrong with the mousetrap example. It's not a living thing; it is a constructed artifact. It's only an analogy, and a bad one at that. Living things are not constructed artifacts. They grow and reproduce and evolve, in a way that mousetraps do not. Science studies the material physical aspects of living things; without taking any position on whether or not the natural processes being studied are there at the behest of a creator.

As for what distinguishes living things from non-living… it is primarily the capacity to replicate copies of themselves: to reproduce.

Response: You asked quite a few questions there, and most of them are excellent ones. The rarity of transitional fossils that biologists mention pertains to transitions between species. There are in fact excellent transitional series between the higher taxa (See http://www.talkorigins.org/faqs/faq-transitional.html). For example, we have a thorough understanding of the evolution of mammals from reptiles: we see the change in ear structure (middle ear bones), jaw structure (fusion of several bones, loss of others), and body posture (from the squat, lizard-like posture to the more upright posture of, for example, canines). And, of course, the evolution of hair. The fossils that show these higher-level transitions tend to be much more abundant than the species-to-species examples. This makes sense, if you think about it. If a new species splits off from its ancestor, it probably does so in a limited range. On the other hand, if a new species eventually gives rise to a new Order, than it is going to occupy a significantly greater range, and we'll be more likely to find it, or its close relatives. Of course, it really helps that we have accumulated much more expertise at figuring where we should be looking for fossils than we used to have. Fossil hunting will always be part luck, but, as they say, luck favors the prepared mind. The paleontologists who discovered Tiktaalik roseae http://tiktaalik.uchicago.edu/) didn't just get lucky: they predicted beforehand that if an intermediate like Tiktaalik existed, it should be found in that spot, in that approximate stratum.

Finally, you seem to be saying that while we have a lot of fossils, we don't have the exact ones you want. I would respond that we do have a lot of those, but not all of them, and more are being found all the time. If you consider that there are tens of thousands (at least) extinct species, and most of them are soft-bodied types that never fossilized, and many others lived in habitats that didn't allow for fossilization (like rainforests), it's just not that surprising we never found a specific transtitional form.

Oh, one last thing- there are flightless birds, but none are wingless.

Response: Darwin was elected to the Royal Society some twenty years before the publication of Origin. This is the premier scientific society in England, and Darwin was elected primarily on the basis of his researches from the five year voyage on the Beagle. By the time he published his ideas on evolution he was well established as a leading member of the English scientific community, and greatly respected for his scholarship.

The claim about being "considered a flunky" is probably the easiest simple factual error in your post that a bit of reading could have fixed for you.

Another factual error is the reason for evolution being so dominant in the scientific community. Evolution is accepted in the same way as any other scientific theory; by the overwhelming weight of evidence. If you look into the history of the matter you will find that one of the major reasons Darwin won over the scientific community to his new model was the considerable amount of empirical evidence he marshalled in support. Since then, evidence has continued to accumulate, especially with the development of genetics and a better understanding of the sources of variation. (Darwin's own ideas on the source of variation is an aspect of evolution that Darwin got wrong, and was not resolved until much later.) A sample of the many lines of evidence for evolution can be found in our FAQ, 29+ Evidences for Macroevolution.

Finally, you conclude by contrasting two different ideas that are not really comparable. Science is of course full of "manmade" models; but the models are describing processes in the world that exist independently of how we describe them. A Christian believes God is creator of the world; but is still able to look at the world and learn more about how it works. Many Christians accept the discoveries of mainstream science -- evolutionary biology included -- and also believe that the world we study was created by God. Many Christians consider that glorification of God incorporates enthusiastic study of the world He made, evolution and all.

You may like to look at the writings of Christians who accept the validity of evolutionary biology. A prominent example in the USA is the biologist Kenneth Miller.

This archive has no official policy on religion. It is true that many of us are unbelievers, but there are also a number of Christian contributors who are very active in our group. If you are a Christian, then you might like to look through the ASA page on origins. The ASA is an association of Christians who are scientists or engineers. We do not endorse everything in those pages; but at least it will give you an idea of the range of views relating to science that can be held by Christians who believe that God created and sustains the world.

Response: I suppose what you say might be true, for a sufficiently perverse definition of faith. The most common definition of faith, though, is (briefly) "unquestioning belief." That definition fits most of creationism, but even a superficial look at the history of evolution will show that it gets questioned a great deal, even today. Evolution is now accepted with extreme confidence in large part because it has held up under all the questioning.

A faith that I, personally, find more meaningful includes trust in God. Such trust in a higher power most emphatically does not include projecting my own beliefs; it means accepting what the Power has set forth, whether I like it or not. My acceptance of evolution is consistent with that sort of faith; if the evidence pointed away from it, I would accept that. But for the life of me, I cannot reconcile such faith with creationism. With faith, one can accept even the most unpleasant news, and I keep hearing creationists say that they could never accept evolution.

You seem to be using faith as a generic put-down. I see all sorts of unthinking attacks on evolution, but it is ironic and unfortunate that you belittle faith in the process.

Response: While it is true that the vast majority of the fossil record consists of small scraps and isolated bones, the detail of your comments are wrong in nearly every respect.

For fossils of our own family tree, we have many bones of all kinds; cranium, skulls, pelvis, limbs, digits, vertebrae, and so on. We provide a list of some of the more significant fossils in Fossil Hominids, including many photos of the fossils. One exceptional fossil is the 1.6 million year old H. erectus Turkana boy, which is almost complete. The famous Lucy fossil is about 40% complete. Many other fossils show skulls and limbs.

Eosimias is a primate genus from around 40 to 45 million years ago. There have been several finds. It is known from scraps; but a lot more than just one tooth. The first fossils, found in 1993, consisted of three teeth and part of a lower jaw. The finders made some predictions based on this evidence; but there was considerable disagreement. Over time, more fossils were found, including a nearly complete set of jaws, and then multiple foot bones. The association is a reasonable hypothesis. The interesting thing about this fossil is the argument that it shows features of the anthropoid apes, thus pushing back the date for divergence of monkeys and apes further than previously thought. This is a debate that is not yet resolved; and goes to show that although individual scientists will build up models, they are not in lock step. Models are vulnerable to falsification as evidence accumulates, and they must pass through the rigours of scientific debate with alternative models. Models are certainly not just built on hopes; they are scientific hypotheses in good standing, with the capacity to stand or fall with the evidence. See Tales from the Crust (in John Hopkins magazine, April 2001, offsite).

Ambulocetus is not "similarly incomplete" at all. Several fossils are known, including one almost complete skeleton. (Image used with permission; click on the image to go to the source at J.G.M. Thewissen's pages, offsite).

This is part of a beautiful sequence of transitional fossils that have revealed the origin of whales, and have resolved a long standing debate about their relationships to other mammals – another example of how evidence is not just interpreted to fit hopes, but really does serve to confirm some models and falsify others. (Specifically; whales descended from artiodactyls, not from mesonychids.) See our FAQ The Origin of Whales and the Power of Independent Evidence.

Response: First a bit of taxonomic clarification because I think a lot of people, particularly those who espouse antievolutionary beliefs, often speak of species of plants and animals as if they are all totally unique and exist in a sort of vacuum (THE bombardier beetle and THE woodpecker come to mind). The reality is that there is a lot of variation and diversity in living things and often one finds that there are multiple (similar) species making up genera (plural for genus) and somewhat similar genera making up Families and so on.

In this case it should be understood that there is no "THE coelacanth", as the term coelacanth actually refers to a whole Order of fishes the Coelacanthini (Actinistia). So saying "THE coelacanth" without specifying that one is referring to one of the still living species, is like referring to "THE primate", "THE carnivore", or "THE rodent" (all different Orders of mammals). In the history of life on Earth there hasn't been just one kind of coelacanth any more that there has been just one kind of primate, carnivore or rodent.

Now, in response to both questioners, it is not true that the two living species of coelacanth (Latimeria chalumnae and L. menadoensis) have remained "completely unchanged" compared to their relatives found most recently in the fossil record (from the Late Cretaceous, some 70 my ago). In fact not only are they different species from those found as fossils they are classified as belonging to completely a different genus than their Cretaceous relatives.

Yes the living genus of coelacanth is remarkably similar in appearance to some of their extinct relatives but they are not identical. For example the genus Macropoma from the Cretaceous belongs to the same Family (Latimeriidae) but is only about a third the size of Latimeria, and there are also a number of other differences in the details of their anatomy. There were probably many genetic, physiological, and even behavioral differences as well but those don't fossilize so it would be difficult for us to know. And although Latimeria is similar to some Cretaceous genera, there are earlier coelacanths that were much less similar in appearance (though still recognizable as belonging to the same Order).

Fossils belonging to the Order Coelacanthini first appear in the fossil record during the Middle Devonian period (about 390 million years ago) and are last found in rocks from the end of the Cretaceous period (about 70 million years ago), however they seemed to have reached their peak of diversity during the Triassic (about 248 to 206 Million Years Ago) (Forey 1998, p. 245). However, despite having been given the colorful moniker of "living fossil", Latimeria (the living genus) is not represented in the fossil record at all.

All that being said it should also be understood that evolutionary theory does not require that a group of organisms (like coelacanths) must change radically over time. If a successful phenotype (shape, physiology, & behavior) is evolved then as long as it remains successful there is no reason it must change.

Regarding the place of the Order Coelacanthini in the evolution of tetrapods (land dwelling vertebrates), few if any paleontologists believe that they are, as a group, ancestral to tetrapods. This distinction goes to the coelacanth's equally lob-finned cousins the osteolepiforms. This makes (extinct) coelacanths more like great, great, great, aunts, than great, great, great, grandmothers to the tetrapods, and living coelacanths distant cousins.

As for Latimeria walking around the sea floor on it's lobe-fins this was a somewhat unfounded speculation by the ichthyologist (J. L. B. Smith) who originally described the genus in 1940 and no one has believe that they do this since they were first observed living in the wild in 1987. However it is interesting to note that the way in which Latimeria rotates it's fins while maintaining a stationary position in the water is somewhat reminiscent of the way tetrapods move their legs while walking.

Response: Tim runs the true origin website. He provides a FAQ there, where he answers the question of credentials as follows:

Q: What qualifications does Tim Wallace have for addressing the origins issue?

A: The first and foremost is a strong desire to know—and make known—the truth, rather than propaganda put out by anyone on any side of this issue. The second is a brain, the effective use of which has been developed through years of reading and discussing both sides of this issue with parties from both sides.

[For those to whom educational/institutional credentials are important, most of the other contributors to this site provide an abundant supply.]

That is, Tim does not claim any special professional qualifications. He prefers that people focus on the arguments themselves.

We agree. We've never bothered to set up a list of credentials for contributors to talkorigins either (though individual FAQ authors sometimes choose to state their credentials). Credibility does not come from credentials. We're also dubious about the credentials he does claim; but you'll have to judge that for yourself from his own writing.

There are some contributors to Tim's web site who have quite good credentials, and yet they till write articles that are utterly without merit and easily refuted by an amateur who is willing to take the time to check a bit of relevant background.

Response: Basically, we aim to provide an education service. The arguements that may arise are secondary. Our main aim is not to argue with crackpots, but to provide information for the benefit of people who are unsure and really want to know how the scientific community responds to the ideas of creationists.

There are many scientists who don't worry about the matter of education in the general community, and focus exclusively on research and on advanced level teaching for those who are training to be scientists. There are other working scientists who spend some time on the task of helping to explain the discoveries of modern science for an interested public.

Welcome aboard. We don't expect or demand that you suddenly change your views; but if you are interested in exploring the matter, we try to give the perspective of conventional science, along with plenty of links to the creationist sites we critique, so that you can compare for yourself.

Speaking personally, my bet is much like yours. H. floresiensis is probably no more closely related to the modern inhabitants of Flores than they are to me. That is, they are another hominid species, not H. sapiens. But I'm no expert, and I'm listening to all sides with great interest.

That section of the FAQ is part of a list of five Myths and Misconceptions relating to Piltdown. The list includes misconceptions made both by creationists and by evolutionists. In each case, we give a simple statement of the misconception, followed by text explaining why it is wrong.

The actual origin of the moon is a fascinating story. Various competing ideas have been proposed, but about fifteen years ago or so one idea emerged as the only one able to account for the evidence. The Moon is accumulated debris left over from a massive collision that took place some 50 million years or so after the Earth's formation. See The origin of the Moon (offsite).

Response: There are a couple of characteristics of science that help to distinguish it from other kinds of inquiry. In my view, these all boil down in some way to the centrality of empirical evidence.

Indeed, science does not require "direct" observation of a phenomenon. Usually the observations are indirect in some way. As long as your model has implications for the empirical world that we observe, by indirect effects or traces from the past or whatever, that can be a solid basis for prediction and for falsification.

Experiment is a useful way of exploring some kinds of phenomena, but many scientific observations don't really fit what you normally think of as "experiment". The fixation on "experiment" seems to be a popular stereotype, founded on the great success of laboratory based science, but ignoring all the science that is based on field work and passive observation. No serious philosopher of science singles out "experiment" as a requirement; they all use the more general notion of observation, for which experiment is only a part.

The simple answer to your question, frankly, is that in so far as you see a conflict between your definitions and ours, you are wrong. Put more kindly, if you look into the descriptions and definitions of science proposed by philosophers, you may recognize that "observation" and "experiment" cover more than you might previously have thought. A model makes predictions; what checks a prediction is observation.

Frankly, I think the real problem is that science -- as conventionally understood by all the philosophers who attempt to define or describe science -- has been enormously successful in revealing details of the past that conflict with some traditional religious beliefs about prehistory. Various idiosyncratic definitions are proposed to try and deny the validity of any empirical check on claims relating to the past. These so-called definitions have no credibility in the philosophy of science, and serve only to obscure and confuse what science is really about.

Response: This archive has no official policy on causes of climate change. It's a bit outside the scope of evolution creationism. You are referring to a passing remark made in a feedback response; not to any of our FAQs.

However, Mark's view is in complete accord with effectively the entire scientific community. The phrase to which you object occurs in a feedback response by Mark made in Feb 2006. Mark is speaking of a general "anti-science" attitude of the Discovery Institute that goes well beyond mere cluelessness in biology. He says:

"…the anti-science attitude that goes with it carries over to other areas where good science is essential to saving lives. I was thinking in particular of HIV denial and denial of climate change, but anti-science interferes in other areas, too."

He's right. Climate change denial and HIV denial are both riddled with the kind of anti-science sophistry that plagues the intelligent design movement and creationism generally.

As is normal in science, there is a ferment of debate and dispute over many details. This debate all takes place within a broad consensus that climate change is real, and that human activity is a major contributing factor. Alongside this, there is a strong anti-science denial going on, with refusal to acknowledge that there is anything particularly unusual in current rates of change, or denial of the close link between climate change and human activity.

This is an institutionalized and actively fostered ignorance that has clear potential for harm. Mark's comments are no more than what you should expect from someone who is in touch with the subject. For example, the Royal Society says:

There is an international scientific consensus that increasing levels of man-made greenhouse gases are leading to global climate change.

Similar statements will be found from the combined national science academies of G8 nations, plus Brazil, India and Russia, the AAAS, the NAS, the IPCC, and many other leading scientific organizations. So we're in good company.

Climate-change denial has a lot more in common with creationism than you might like to admit.

Author of: Darwin's precursors and influences
Response: "Fitness" has several meanings. The original sense was "fitted to the environment" and it was this sense that Darwin used, although I do not think he used the term "fitness" in any other sense. For example, in the Origin, he says

As natural selection acts by competition, it adapts the inhabitants of each country only in relation to the degree of perfection of their associates; so that we need feel no surprise at the inhabitants of any one country, although on the ordinary view supposed to have been specially created and adapted for that country, being beaten and supplanted by the naturalised productions from another land. Nor ought we to marvel if all the contrivances in nature be not, as far as we can judge, absolutely perfect; and if some of them be abhorrent to our ideas of fitness.

and in the Descent he says

at every stage in the process of modification, all the individuals which were in any way better fitted for their conditions of life, though in different degrees, would have survived in greater numbers than the less well-fitted.

The term "fitness" as a technical term of evolution comes later. Initially, Ronald Aylmer Fisher, in his groundbreaking (and occasionally objectionable!) book that mathematised evolution, used the term "reproductive investment". This was defined as "fitness" [JStor link - needs a subscription] by J. B. S. Haldane.

Fundamentally, fitness is either absolute - the ratio of genotypes from one generation to another - or relative - the average number of genotypes in a population relative to other genotypes, after reproduction. In both cases fitness measures the rate at which one genotype spreads through a population over time.

Darwin did not invent the idea of natural selection, but he was the first to see it as a motivator of change. See the Darwin's precursors and influences FAQ for details.

Response: I fully agree with you. In my view, there is only "selection", which has subsets of "sexual", "artificial", and perhaps a few others (e.g., "species"). "Natural selection" usually refers, however, to survival-based differential success, whereas sexual selection refers to reproductive differential success. Since at base all selection is about fitness of variants, and sexual selection is one aspect of that, and it can also include survival factors, I think the term "Natural selection" is otiose, and should be dispensed with. I doubt this wills way many biologists, though.

Darwin started his argument with a distinction between selection in artificial cases, such as animal husbandry, and selection in "nature". This is the reason why "Natural selection" is a class of selection in most peoples' view. I think the distinction itself is artificial...

Complex behaviours like homosexuality can arise as an indirect consequence of a range of other traits that may well be selective. It's an open question; but not nearly the problem for evolution that you might think.

Response: We don't strictly know how everything got started; but cosmology has told us a lot about the history of the universe back to extreme conditions in which conventional physics breaks down. This is reasonably seen as explaining the origin of the universe as we now experience it from very different conditions; but it does not stand as a complete account going back indefinitely in time. It gets subtle, because even time itself is a feature of the universe that was very different back then. It's probably fair enough to speak of the origin of the spacetime in which we now live.

Response: There are known physical constraints on the behavior of energy and matter. These limit the possible states that matter can take. The study of these limitations are the physical sciences, particularly relevant is Chemistry. So in this sense, the chemistry of life is not "random." There were two parts to the classic Darwinian view of evolution, random heritable variation and natural selection. After one hundred and fifty years of study by thousands of scientists, we know today that the heritable variation is not entirely random as it is constrained by chemistry, and that natural selection is more complex than imagined by Darwin. The quickest way to promote complexity in a system is to add a bit of randomness. You will find the begining trail of a full discussion in "Five Major Misconceptions about Evolution".

As to the origin of life, Darwin had nearly nothing to say nor does the validity of his theory rest on the exact nature of the origin of life. The "lighning bolt struck a pond" is a mishmash of a comment Darwin made in a century (plus) old letter, and the well established and widely replicated production of organic molecules in the Miller/Urey experiment.

Secondly, TalkOrigins is quite unlike creationist organizations by actually linking opposing websites. There are also dozens of links to creationist sites and publications in the individual articles making up the archive. You obviously have not looked carefully at the site, and I invite you to do so.

Finally, there are a goodly number of articles here on the use of various dating methods. You can use them to look for those errors you think are so prevalent.

Response: Because a major part of evolution, and the basic cause for adaptive evolution, is selection -- the very opposite of chance.

Response: Oh boy…
  • Almost none of the bird intermediates mentioned are hoaxes. There is one well known hoax, Archaeoraptor, where a popular magazine (National Geographic) rushed into publication without waiting for a proper scientific check, and this fell apart almost immediately. This one hoax had effectively no impact on science. It was exposed almost as soon as it was published, and it was never published in scientific literature. (It failed to pass peer review twice before NG rashly went ahead with their article.) That's it. There are no other hoaxes of any significance.

    By the way; there is a crying need for a good FAQ on the evolution of birds in this archive. There is a brief mention in the transitional fossils FAQ; but it is way out of date. Since it was written there has been a host of new evidence of undoubted authenticity bearing upon birds and theropod dinosaurs.
  • There are heaps of intermediates between mammals and reptiles. It is one of the best documented transitions in the fossil record.

  • Your comments on Neanderthals are weird. No; they have not been proved fully human in the sense of being fully Homo sapiens. They represent a distinct human species or subspecies; now extinct. They are far outside the range of diversity seen within the one human species now living on Earth. Their skulls in particular have characteristic differences. See our FAQ Creationist Arguments: Neandertals.

  • Evolution and other natural processes routinely produce new information. See Apolipoprotein AI Mutations and Information; and a more technical look at Information Theory and Creationism.

  • You are ludicrously wrong about similarities of frog, chimpanzee and human DNA. The DNA difference between us and chimpanzees depends on how you measure it, but sequence similarity in coding DNA seems to be less than 1% difference. They are really close. The differences with frogs are far greater; way above the 3% you cite.

  • As for differences with "the most basic form of life"; if you mean differences from a primitive common ancestor, then it is a prediction of evolution that all living organisms should be equally far removed, in the sense of having evolved for the same amount of time since then.

  • Dating methods do not simply "assume" a closed system. Some dating methods don't require that assumption, like the concordia-discordia methods, and others test for it. See Radiometric Dating.

  • You're badly confused about Polonium as well. It is extremely rare in nature; found only as trace amounts in Uranium ore, in ratios of around 100 micrograms to the metric ton. This ratio is about 1 to 10000000000; pretty much the same ratio as their decay rates. In other words; exactly what we should expect.

  • The fossilized cells from a T-Rex are exciting, and there is even evidence that some proteins may have been preserved. No DNA has been detected. There is nothing that conflicts with the age of the fossil. See Dino Blood Redux.

Response: Many thanks. I find that Aristotle improves each time I read him, and that a lot of the bad reputation he has is either due to the historical misunderstandings of modern biologists, or the purposeful polemic of the renaissance humanists, who overstressed their differences with Aristotle to downgrade the scholastics.

The problem of historical imagination when trying to understand someone in their own context is large. I think it requires that you set aside everything you "know" from later interpretations and just read the author as if you had just met them for the first time in that time and place. For that reason, I have suggested that Aristotle is actually not using technical terms most of the time, just ordinary words that became technical terms later on. Read him as a "common sense" philosopher, and you get a much better opinion of him.

Response: No problem. Glad to be of service.

One other fellow thought that I was too harsh. On reflection I agree. I should not have dragged in used car salesmen.

One may (and I often do) encounter creationists who are merely terribly ignorant. On a very abstract level they are not lying, they are merely repeating lies. However, it is my invariable experience that these ignoramuses will persist in their ignorance regardless of the evidence presented to them. They will also spout many Bible verses that they do not understand either.

Then they are liars too.

As noted by Thomas Aquinas in his Summa Theologica

"In discussing questions of this kind two rules are to be observed, as Augustine teaches. The first is, to hold to the truth of Scripture without wavering. The second is that since Holy Scripture can be explained in a multiplicity of senses, one should adhere to a particular explanation only in such measure as to be ready to abandon it if it be proved with certainty to be false, lest Holy Scripture be exposed to the ridicule of unbelievers, and obstacles be placed to their believing."

Response: As I understand it, New Zealand was never connected to a continent and so its fauna is only that which could traverse a long sea voyage (of about 2,250 km). I saw today on the Dinosaur list that fossil snakes were not found in New Zealand, but rather:

It turns out that certain freshwater fish have palatal tooth-bearing elements that, if broken in a certain way, are practically indistinguishable from fragments of snake pterygoid bones broken in a certain other way. The tooth morphology and attachment is remarkably convergent, but the teeth in the fish are relatively enormous, so remains of a tiddler can be seen as evidence of a giant snake.

The suspicious fact (the dog that didn't bark, if anyone knows their Holmes) was the absence of any snake vertebrae from the same deposit.

New Zealand still has no snakes.

Response: It is in fact an unwarranted supposition that our ancestors were dark skinned. Modern apes, like the chimp or gorilla, have pale skin, so it's likely this was the ancestral condition. We know that those who are dark skinned in southern Asia and Oceania evolved this secondarily, in response to the need to reduce Vitamin D synthesis due to a lack of hair. So it is likely that the original humans evolved dark skin after or along with the loss of hair.

It is true that Europeans have longer and thicker hair on their body than Africans usually do. This is not because they have more hair, but because their hair growth has been turned up a bit. As it happens, we have roughly the same number of hairs per square inch as all humans, and in fact as all apes. Europeans and Asians are a derived form of human variation. The ancestral modern humans are African, although there has been a lot of genetic traffic to and fro.

The idea that Africans are more "apelike" in fact comes from well before evolution was developed in biology. The older idea of the Great Chain of Being supposed that organisms were arranged on a scale from simple to complex, and in the 18th century, this was used to justify European domination over the slaves they were taking from Africa. "Negroes" were placed between Europeans and apes, and treated as children or work animals. Some people after Darwin combined this scale with evolutionary change to imply that "Negroes" were not "as evolved" as Europeans, and hence to justify paternalistic policies of control. It was not, in itself, a conclusion of evolution but of prior ideas that were forced into an evolutionary worldview.

Why that prejudice survives is due to social attitudes that have a deep history in western thought.

And evolution hasn't stopped, either among Africans or anyone else. We are constantly evolving, to meet new environmental challenges, including our use of dairy animals, exposure to diseases and industrial pollutants, and so forth. I hope this helps.

Response: First, just to get it out of the way, neither coelacanths as a group nor the living genus Latemeria is thought to be ancestral to amphibians (see my earlier response on this above).

If creationists (young Earth) were simply claiming that a population of non-avian dinosaurs had survived into historical times (roughly the last 9,000 years) or even to the present that would not be a problem for evolution at all. Evolutionary theory does not mandate that any group of organisms must becomes extinct, and as you note, there are other organisms, like the coelacanths, that were once thought extinct but turned out to still have living representatives. In the case of dinosaurs, they have been with us all along (though we didn't understand this until fairly recently) in the form of birds.

But this is not what creationists are arguing. What they are actually trying to prove is that (non-avian) dinosaurs and humans have in fact coexisted throughout the entirety of earth history, which they believe is restricted to the last 6 to 10 thousand years. This claim if it could be substantiated (and it hasn't been) would be problematical for not only evolutionary theory but all of modern science.

See the following from the Index to Creationist Claims for more on some of the claims of antievolutionists regarding this issue:

*Note: Even though plesiosaurs and pterosaurs are not dinosaurs they were Mesozoic contemporaries of the dinosaurs and creationists make the same sorts of arguments regarding them.

Response: It takes more work to refute creationist's lies than it takes them to make them. I have looked at O'Leary's drivel, and I have ordered the relevant books. Now I am out some money if I read them or not. And if I read them I will lose a few more IQ points to boot.

Then I will need to write a rebuttal (which nobody pays for) and then wonder if it was at all worth the effort. This is why few people of sound mind take on this sort of work. But I did have the great pleasure of having something I wrote cited in the Dover Pandas Trail, and even in the decision written by Judge Jones.

So, I feel that the effort is worth it after all. Others, who contribute to TalkOrigins and TalkDesign and our other associates, have had simillar pleasures. The anti-science sites we also link are living examples that the Dark Ages are only a moment away.

Thanks for the heads-up.

Response: I agree with you about the belief - one accepts the evidence and arguments of evolution, one does not believe it. But the term "evolutionist" has a legitimate meaning in addition to the skewed misunderstanding of creationists. It typically meant a scientist who specialised in evolutionary biology. However, creationists have indeed made it a term that implies some sort of religious commitment. It no more means this, though, than "dentist" means one who believes in teeth, or economist one who believes in the economy.

On the point about spirituality, it is true that evolution doesn't challenge religious belief, and the majority of religious denominations accept that. See the God and Evolution FAQ, and the list of religious bodies that accept evolution at the NCSE site. But the fact of evolution challenges some claims made by scriptural literalists who (arbitrarily) treat some passages of the Bible or other scriptures as literal history or cosmologies.
