I found an excellent website that discusses horse evolution for the lay person. It is on the Florida Museum of Natural History's website at http://www.flmnh.ufl.edu/natsci/vertpaleo/fhc/firstCM.htm Creationists routinely misrepresent horse evolution when they depict it as being a straight line. (The horse evolving from a small, multi-toed forest browser to a large, single-toed plains dwelling grazer.) They then discredit this long abandoned idea by pointing out horse fossils that have multiple toes and browser dentition that are the same age as "later" horses that have single toes and a grazer dentition. The answer is that evolution is a bush, not a straight line. Some horses retained their forest browser lifestyle while others took advantage of the new niches afforded by the grasslands that opened up as the world cooled during the early Miocene 20 million years ago. The grassland horses evolved traits useful to living on open plains. They evolved grazer dentition to help deal with the tough grasses that had also recently evolved. Horses increased in size probably as a result of needing a larger gut to digest the tough grasses which are full of silica. As so often happens in nature, interaction between life forms spurred evolutionary change. The grasses where driving the evolution of the horses and the horses in turn where driving the evolution of the grasses. In addition, plains horses lost all of their toes except one. On the plains multiple toes could slow a horse down when speed was essential to escape from predators. The forest browsers on the other hand, did not change that much because adaptations useful on the plains did not offer the same advantages in the forest. Eventually, the forest horses died out leaving us with the modern horse that exists today.

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

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.

Your definition of evolution is simply adaptation which all life forms possess to maximize their survivability. Additionally, acquired characteristics are not inherited (i.e. a body builder's children will not be born with big muscles). An organism can only reproduce after its kind and will only reproduce per its DNA code. Ex: A common ancestor of the dog kind gave rise to other breeds of dogs after many generations, but the information to produce other breeds already existed in the DNA of the original dog pair. Many generations will produce only other dogs, and not another type of creature. This is exactly as Genesis 1 states, and holds true for all life from bacteria to plants to monkeys to humans. Finally, a five year-old can make a sand castle; time, matter, and chance cannot. A scientist cannot make a single-celled organism or even a DNA molecule, but you claim time, matter, and chance did? Time is short; will you be ready to meet the Creator? He revealed all His details in 66 books.

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.

I have to say I don't have much resentment against atheists or evolutionists...but how come I saw so much resentment in the comments and responses against Christians or creationists from the atheists and evolutionists? I am a Christian myself and I hope non-Christians can "respect" what I believe in and stop the mockery. We are all mature enough to do this, aren't we?

As for the mousetrap comment from Mr. Robison... yes, you could rearrange the components into another functional mousetrap without using all the components, but didn't you just became the "creator" of the new mousetrap? An intelligent being has to design the new mousetrap, assemble it, and eventually put it somewhere meaningful in order for the mousetrap to function right? Well...maybe mousetrap isn't the best topic for discussion here since it is non-living...but I am just interested to see what your response is.

Second...we know that all known living beings are composed of different chemical compounds/elements/compositions. could you explain the difference between a group of complex chemical elements & a living organism? What turns those complex chemical compositions in to a "living being"?

thanks!~~ May God Bless you~~

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.

Question on rarity of fossils....

Evolutionists use "rarity of fossils" to explain the lack of any smooth transition of taxa in the fossil record. It is used to "explain" the fact that all major animal families appeared suddenly in the record, and why extinct forms all disappear just as suddenly.

There seems to be a disconnect between the "gradualist" model of evolution and the, well, reality of the fossil record. We've found dinosaur skeletons of the same species at different spots around the globe. Considering the purported "rarity" of fossilization, and the vast quantities of "undiscovered" transitonal species that must have existed to give us our present diversity, to find two of the same species or even family of creature in different locations should be statistically miraculous! But we've found multiple examples of homo erectus in Africa, China, Java, and Europe... we've found multiple examples in different locations of Homo Habilus, Neanderthals, T-Rex, Triceratops, Stegosaurus, Trilobites, etc. But huge lack of any fossil evidence of their "common anscestors" or "common descendants".

Multiple sites showing the same fossils even are used to explain/prove plate techtonics...However, they fail to explain WHY... Why the fossil record is void of the undeniable transitional forms that must have lived, not just for a bried period, but for long enough to evolve again into the next genus or family of animals. Land mammal to amphibious mammal to whale (the so-called evidence on this site is very subjective and argumentative) Land mammal to Bat. non-flying reptile to flightless bird to flying bird back to flightless bird to wingless bird. Fish to finned reptile to limbed reptile back to limbless reptile to venomous limbless reptile and land reptile to aquatic reptile and so on and so on.

Evolution is said to be constantly happening at a pace too slow to see, but we find it must move quicker than the fossil record can/could record... the fossil record shows stasis of species between appearance and extinction in the record. Any creature that has fossil remains on record such as the coelocanth, crocodilians, etc that are "living fossils" having (insert Richard Attenborough's voice here) "remained virtually unchanged since prehistoric times" is considered so because we have "ancient" fossils, and "modern" living representatives, so there is no dispute that these creatures have "bypassed" evolution (they actually say "have changed very little" or "virtually unchanged" to at least hold the view that evolution is still happening, just even slower than "normal"). We don't have fossil evidence from every time period proving they have "been around" all this time, we have no fossil evidence showing the evolution between major animal and plant phyla and orders and families.... and it is "explained" by saying "Fossilization is just so damn RARE!" We just have many examples of This and That and the Other...just no examples of all that is missing inbetween...because of the so-called "rarity" of fossils.

Is this evidence of "punctuated equilibrium", or is it merely a question to be ignored?

Or is there some other theory that would explain this question?

I hope you post this question, as I'd really like to see the explanation. I considered using poor grammar, rudeness and misspellings, which appear to be a requirement for non ass-kissing posts to be presented in the feedback column. That, or reposts of typical, easily refutted creationist points that have been addressed ad nauseum.

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.

This is disgraceful. You are lying to people. I am 17, and I am able to pinpoint all the horrible lies you have put on this site. You must lie a depressive life to believe in evolution...Christians have a Savior and an answer to just about everything in life. The Bible has never been proved false. In fact-the scientific statements that it makes are 100% accurate. Both evolution and the Bible are accepted by-faith. That is the only thing they have in common. I'd rather believe that we [as humans] have a purpose in life [To glorify God] and that our Saviour created the world--than to believe in a manmade theory made up by a man who was considered a flunky until his ridiculous book.---wouldn't you?

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.

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.

A comment about Woolly Mammoths: Evidence of Catastrophe? Sue Bishop Philip Burns.

The Mammoth articles are getting obsolete due to a lot more research. First about the mummies, several more have been discovered, the Jarkov Mammoth on the Taimyr peninsula 1998, dated 20,300 carbon years BP, the Fishhook mammoth, 100 years younger and the Yukagir mammoth, 18,350 carbon years BP that has been on display at the Expo in Japan.

No the mummies were not flash frozen but we have also to take into consideration that those mummies “survived” the Hypsithermal or Holocene thermal optimum, when Siberia was much warmer than today, the treeline reaching to the coast of the Arctic sees with the permafrost probably minimal or completely gone. The mummies may have been preserved as peat corpses not as deep freeze meat.

Yes, the mammoth was suited for cold but that’s not an explanation why they could survive in Siberia during the last glacial maximum and perished in the Holocene. Note that the Mammoth steppe was also inhabited by horses, antilopes (Saiga), camels, lions, tigers etc etc. Fungi spores (dung) show that the animals were abundant and their metabolism would certainly require large amounts of food available throughout the year. Steppes are only productive at certain temperatures, certain amounts of sunshine and water. Neither is correct at the current desert tundra locations where they once roamed. The vegetation was a unique mixture of low latitude taxa (grasses, wormwood etc) and taiga taxa like the arctic poppy, with no equivalents anywhere today.

No, the tusks were not used for scraping snow away from the ground. Would be problematic anatomically, moreover female woolly mammoths had only small tusks of a foot or so in length and they did survive. Beetle (weevle) remains however show southerly species in a habitat with little or no winter snow. The long grasses would remain available throughout the year without tusk tricks. Isotopic research by Daniel Fisher Ann Arbor Michigan (not published yet) suggests that the animals did not migrate annually.

An manuscript has been submitted to Quartenary International about the cause of the extinction of the mammoth and it was not kill

The skeletons of supposed human ancestors constist of little more than tiny fragments of teeth and jawbones. You people just extrapolate them to suit your hopes. The supposed eosimias fossil consisted of just a single tooth! Ambulocetus is similarly incomplete and inconclusive, merely a hopeful reconstruction to support your conclusion.

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 skeleton

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.

I was just curious as how evolution explains "living fossils". Creatures such as the coelacanth and triassic triops can be found in the fossil record 200 million years ago and are in exsistence today completely unchanged or "un-evolved". The coelacanth is completely unchanged in comparison with coelacanth fossils. And is widely described as one of the steps in the evolution of the "walking fish". Also the coelacanth in the wild uses its "arms or legs" in no way shape of form for walking, crawling or any way other then swimming. And also the coelacanth uses pores to detect the electro volatage in the muscles of its prey to catch it's prey. Rather advanced for an ancient fish. To me an ancient fish that did not evolve, proves that nothing evolves.

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.

Who is Timothy Wallace?

I have seen several articles written by him on Creation Science sites and www.trueorigin.org but nothing identifying him or his background. Does anyone know about him or what his credentials are.

Response

From
Chris Ho-Stuart
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.

Hi, I'm a young-earth creationist, am 15 years old and I have a question about your website. While I don't agree that creation is a pseudoscience, why, if you think it is a pseudoscience, do you take time to answer every single claim that creationist 'crackpots' make? If they're just idiots, why waste time arguing with them? You should devote your time to scientific research, not arguing with "crackpots".

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.

Thankyou, your website is well made. I appreciate the work you have done . I was hoping if you are aware of a group of people found on flores island in indonesia. This same island also had small pygmy stegodons and large Komodo dragons. Thru a large amount of time the stature of a group of people became smaller to fit the living space of the island. (same with the stegodons) I believe these people were still around 13 to 18 thousand years ago and may be of homo erectus decent. Thier stature is just over 3 feet in height and weighed about 50 pounds. I just wondered if creationist can explain this exciting new group of mans relatives that lived quite recently. I know there is speculation of they themselves being modern pygmies also found on the island. The evidence of fossils and the dating is proven they are not.

This is still very topical and unresolved. We have a FAQ on Homo floresiensis; and it has more links for looking into the matter further, both for various ideas within the scientific mainstream, and for creationist responses.

After reading a few books about the human brain and how it works, at least what we know now, I've come to the conclusion that religeon is an evolutionary adaptation, selected for over millions of years, as a way of bonding and easing tensions among individual members of small bands of our human and pre-human ancestors.

I have been a student in biology for over a year now. It is my opinion that this site is one of the most inspiring and creative I have witnessed yet. Although I was taught biology from a creationist viewpoint, I simply could not believe in the theories and viewpoints that creationists teach. I could never truly understand anything in biology without evolution. After studying your site, I have come to the conclusion that evolution is the most reliable scientific theory about the orgins of life and the laws of nature. I have come to realize the evidence for evolution and discovered the simple processes involved which explain the diversity of all life. I have come to a better understanding of human evolution, artifical intelligence, technology, sexuality, genetics, physics, and genetic engineering. Although I still believe in God to an extent, evolution has allowed me to fully understand nature and the natural processes of life.

Sirs, I had always understood science and scientific theory to be defined as follows: First, information is gathered by careful observation of the phenomenon being studied. On the basis of that information inductive reasoning forms a hypothesis. The phenomenon is further tested by observations and experiments performed and repeated various manners to confirm the hypothesis. If the original hypothesis successfully meets all these tests, the hypothesis becomes accepted as a scientific theory or law.

There seems to be an apparent contradiction between the above and the definition of a scientific theory as written on your website. You list the two identifying characteristics as 1. It must be falsifiable, and 2. It must make verifiable predictions. Most notably you do not seem to require observation or experiments of the phenomena.

Which definition is true, and why does there seem to be a difference between them?

Thank you for your time!

Response

From
Chris Ho-Stuart
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.

The term "Fitness" as it applies to evolution that an organism means what?

Did Darwin invent Natural Selection?

Response

From
John Wilkins
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.

Hi there! First of all, I'd like to say I immensely enjoy your website. I've studied evolutionary biology deeply in my (believe it or not) philosophy-classes, and I've read almost all of the articles here, and I come back regularly to check on the "what's new"-section. Without wanting to sound arrogant, I do believe I understand the core ideas of evolutionary biology pretty well. However,due to confusing word-use in papers and books (and also by Darwin), a question remains. To me, sexual selection is a limited subset of natural selection. Natural selection is about the reproductive succes of an individual in relation to its environment, in other words, individuals who have traits which enhance their chance of reproducing within their environment also have a greater chance to pass those traits on to their offspring. Sexual selection, to me, is essentially about the same thing, only the selecting environment is limited to the preferences of the opposite sex, or the power struggle between same-sex individuals. Those who have traits that attract or secure mates with more succes will, again, have a better chance of reproducing and passing on those traits. I understand that this might seem a special case, because natural selection is mostly discussed in terms of survival, and some "sexually selected" traits seem to be bad for survival. But since survival is actually only a means to the cause of reproduction, I keep wondering why I see so many papers which make natural and sexual selection two different mechanisms. Isn't sexual selection dependent on exactly the same mechanism as natural selection? And isn't separating the two at most a teaching instrument to explain the biological traits which seem counterintuitive to someone who views survival, and not reproduction as the most important factor in evolution? If so, it definitely failed for me, I was confused for years about the status of sexual selection. If it is clear that it's all about reproductive succes, then surely SS is a (remarkable but understandable) subset of NS, no? If I am in any way wrong in my assessment, please correct me. I've spent too many years on understanding ToE to remain wrong about this basic issue. Thanks, and congrats again on the site. Btw, special regards to the author of "29+evidences for macro-evolution." You gave me a great arsenal of arguments. Thanks. Kim

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...

We address this as claim CB403. Briefly, it is by no means clear that there is no useful purpose; nor is it clear to what extent it is a heritable trait subject to selection.

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.

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.

Nearly all of the bird intermediates mentioned have in fact been provan to be hoaxes. I find it completly deplourable that these would be used and it only shows that evolusionist are actually more interested in forwarding there claims of history upon philosophical ground rather than cold hard evidence, The fact is there actually are not any proven mammals/Reptillian intermediates, and further more there were clear double ups in the range Human like skulls, There were three neanterthal skulls which incerdentily has been proven to be fully human and most likely suffered from bone defect such as rickets in cold enviroments as a result of poor vitamin D production due to the environment. This has also been strongly suggested that the neanterthals were infacted dark coloured in skin tone, likewise you find that lighter coloured people don't traditionally live in hot climates due to possibillits of cancers due to eccess sun. Simply natural selections works within the boundaries of the genetic information that is already available. It most definately can not produce information therefor DNA/Genetic Info without it being introduced externally. This is were evolution falls over because it can not possibly give an account of how life origanated let alone how millions upon millions pieces of information can be produced out of nothing within any given cell. One must remember that within the human DNA strand there is enough info to fill 1000 books at approximately 1000 pages at A4 sizes with a font of arial, sized at 10. This is an astronomical amount of data and then to think that there is accordingly 3% difference between us and the Chimp, Just think there is also 3% difference between us and the frog. Having said that upon closer investigation it is found that all living organisms are as far removed from the most basic form of life as all other living organisms, this effectively negates evolution. Just one last apple for the cart, Our dating methods are flawed, It is asumed that we are in a closed system which means nothing is added and nothing is leached away except that this is not true Infact dating is done through the measureng of decay of certain elements, it is fact that polonium has an extremly short decay span and infact is only produced from the decay of uranium which has a decay rate of approx 250 millian years per half life. there after 250 millian years at todays rate of decay you will infact still have half of the uranium you started asuming that the system is completly closed. The massive problem with this is that you approx 1 million years worth of uranium decay to produce enough polonium with which to measure it decay times, incedentily this has to happen in a matter of a few very short days. That makes it extremely obvious that todays rate of decay have not been constant and therefore any dates given by any naturalistic means can not be trusted, it is intrsting to note that polonium decay has been observed all over the world and not just in a secluded spot. Having said that carbon 14 dating is good for approx 50000 years max. DNA & red blood cells last for even less than this, however evolutionists scientist have infact discovered red blood cells with in T/Rex Bones which can only prove that this world is much younger that mainstream science would teach. The reality is that evolution relies on faith as much as any other religion and is therefore inherently unscientific. This makes evolution as much a religion as any other

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.

John Wilkins’s Aristotle article (February Feedback) is most interesting, and his ‘benign and malign’ estimate of the philosopher’s influence unusually fair and balanced, and also productive, in that it prompted me to go web-hunting after Atomism through the ages. But wanting to get my teeth into form and substance, I looked up ‘hylomorphism’ on Google, and felt like I was starting to bite on a large piece of sticky toffee that threatened to pull out all my fillings and shatter half of my teeth. It really seems most difficult to put oneself into the mindset of earlier times. Above all, one must avoid what Owen Barfield called ‘logomorphism’, projecting our own thought patterns onto people of an earlier age (or a child).

At present I’m into the history of mathematics and its applications, and here is one definitely malign influence of a philosopher, in that Gauss decided not to make public his discoveries in non-Euclidean geometry, to avoid disputes with the ‘Boeotian’ followers of Kant, whose philosophy took Euclidean geometry as its very basis. Still, Riemann came along in plenty of time for the necessary mathematics to be available to Einstein for his General Theory of Relativity.

Finally, in no way do I confuse teleological explanations with accounts of how things happened. But here’s one for you all to enjoy – why did God create Darwin? With the Anglican Establishment dominating the later Paley-O-Zoic, and after centuries of God’s name being taken in vain by being used as an instrument of the social order, He raised up Darwin to pull the rug from under their feet.

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.

Hi!

My compliments to Richard Wein for his article Not a Free Lunch but a Box of Chocolate, in which he criticises William Dembski's book No Free Lunch and Edward E. Max for his article Plagiarized Errors and Molecular Genetics.

The final article in the Wein-Dembski interchange is The Fantasy Life of Richard Wein: A Response to a Response, in which Dembski mentions a case, where a Bell Labs physicist published apparently the same research results twice though claiming they were from different experiments. A case of self-plagiarization? For Dembski the verdict is: Intelligent Design!

There is specified complexity: the first publication is the specification for the second, and results data had a random component with a very low probability to reoccur by chance, so there is complexity.

What's funny is (at least to me), that Edward E. Max in his article mentions two cases where publishers were accused of plagiarizing books from other publishers, not of doing "intelligent design", though the argumentation was the same: the reoccurence of exactly the same, supposedly random, errors.

With a design inference method à la William Dembski's, there is no difference between design and plagiarism, so anything can be called designed - all we need is that we have seen the same thing somewhere before!

Gary Hurd's response to the high school science teacher in the March 2006 Feedback presents a quite evenhanded, fair, well-reasoned and truthful response. To quote, "Creationists lie. They always lie, they lie worse than politicians, they lie worse than used car salesmen, they lie when their argument is weakened by a lie."

I had previously given Creationists the benefit of the doubt, but now I know better. Science, as represented by Mr. Hurd, has spoken and shown me the error of my ways. Thank you for setting the record straight.

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."

I have tried getting a response to this question on IIDB Evolution forum, and mostly all I am getting is a lot of static. I suspect that is because no one has an answer.

Why are there no land based snakes in New Zealand?. There are snakes all over Australia and Tasmania, and NZ is not that far away.

There have been fossil finds of snakes in NZ dated to around 15-20 million years ago, so the idea that they never got there is a bit damaged by this. And why did they die out?

I would have thought that given the huge number of birds, and given how much many snakes like bird's eggs for breakfast, that this would have been a plus for survival.

Of course, the opposite could be true, and Moas in particular might have enjoyed snake fr dinner.

As I said on IIDB, I have been close to stepping on a tiger snake several times in a fairly built up area, so the subject is of genuine interest. Have any studies been done at all? Why Australia, Papaua, New Guinea, Indonesia, and not just over the creek in NZ?

There is nothing here on the subject, nor can I find anything on any other web site.

Is there an answer, or is it just something that nobody has studied,or even (seriously) speculated on.

THanks, if you respond, and thanks for a great website.

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.

My comments are about evolution. It's been a thorn in my flesh for a long time mainly because I do not believe in it. I know that insects, some reptiles have evolved over years due to climatic conditions, food availability or not availability but what made baboons, apes evolve to white people. I am simmering with anger at the moment because I am watching UKtv History a TV channel in Britain. When ever evolution is discussed it is always associated with black people even now it's dark skinned people who are shown in the programme walking like apes. These million old fossils are in countries where dark skinned people live, Africa, Indonesia so how did they become white people? Are they albino apes? What angers me most is the fact that when white youth see black people they make these ape noises and sounds. It's white people who are covered in hair, we are not, our hair is very minimal. These programmes never discuss the connection of the white race to evolution it always ends up with dark skinned people and to me all these things are just a way of perpetrating a way of thinking which undermines dark skinned people. If there is evolution, why has it stopped?

Response

John Wilkins

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.

Dear Talk.Origins,

My name is Nathan Powell. I am 16 y.o., and am a Creationist. I just have a quick question. Maybe I am missing something here, but it seems to me that you don't need to worry about the dinosaurs living with man controversy, because the coelacanth is still alive today, and some of them supposedly evolved into amphibians 300-350 million years ago. So since this is true why are you trying to disprove dinosaurs ever lived with man? Thanks!

Sincerely, Nathan Powell

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:

  • CB930. Some fossil species are still living.
  • CB930.2. A plesiosaur was found by a Japanese trawler.*
  • CB930.3. Dinosaurs may still be alive in the Congo.
  • CB930.4. A pterodactyl was found alive in Jurassic limestone.*
  • CC101. Human footprints have been found with dinosaur tracks at Paluxy.
  • CC120. Baugh found a fossilized finger from the Cretaceous.
  • CC130. A petrified hammer was found in Cretaceous rocks.

*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.

I am a conservative Christian, and my instinct is to interpret the Bible literally wherever possible. Although I was never completely convinced of young-earth creationism, I was what you might call a YEC-sympathizer.

Thanks to sites like yours and a few books, I now realize that YEC is false, even though some of us would love to believe otherwise.

Thank you for investing the time to create such an outstanding site. Now that I realize how overwhelming the evidence for evolution and an old earth is, I marvel that you have the patience to explain it. I am embarrassed by my own former ignorance, and grateful to you and others for taking the time to educate me.

I implore my fellow Christians to remember that all truth is God’s truth, and to seek truth with humility. We are only human, and are therefore prone to self-deception and dishonesty when listen only to our own little group. Scientists – both believing and unbelieving – have much to teach us if we will listen.

ID advocate Denyse O’Leary provides summaries for the essays in philosopher David Stove’s posthumously published book, “Darwinian Fairytales,” here:

Agnostic Aussie philosopher: Neo-Darwinism's Failings

Judging by her summaries, his arguments sound (only superficially, of course) convincing and a firm rebuttal, or list of links, might be of use to anyone unfortunate enough to be tempted to accept them.

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.

Thanks for all the hard work. One thing that disturbs me is the use of the word "Evolutionist". It sounds like evolution is a faith or belief, when it really is a natural process that scientists have worked hard to understand. I prefer to say "I understand evolution" rather than "I believe in evolution". It is similar to saying "I understand photosynthesis" or "I understand gravity", or "I understand the process of decay".

ps. evolution as a process is no way a challenge to God or Religion or spiritual belief. One's spritual understanding goes through evolution during one's lifetime, too. As Grendel said, 'Things change and alternatives exclude.'

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.
