More on Young-Earth Evolutionists

The Old Testament uses the word translated into English as “bird” to mean any flying creature, which includes a bat.

In my previous post, I wrote about the misleading concept of Young-Earth Evolution (YEE) promoted by Answers in Genesis (AiG). In essence, AiG is worried about young-earth creationists who do not wholeheartedly conform to its positions on various issues related to creation and evolution. It says:

YEE ideas are needlessly and dangerously accommodating evolutionary assumptions, ideas, and language. The advocation of subtle ideas out of step with clear Scripture undermines biblical authority, sows confusion, and is a breeding ground for compromise.

What are these “subtle ideas out of step with clear Scripture”? It turns out that they are ideas about which Scripture says absolutely nothing! For example, AiG takes issue with Dr. Matthew McClain, a young-earth vertebrate paleontologist who says that birds are more similar to dinosaurs than they are to any other creatures. This is, of course, a true statement (birds and dinosaurs share an enormous number of similarities), and Scripture says absolutely nothing about that. In fact, while Scripture describes individual animals that were probably dinosaurs (see Job 40:15-24, for example), it doesn’t mention any group of creatures that can be collectively referred to as dinosaurs. Thus, the Bible makes no comparison between birds and dinosaurs.

Why, then, does AiG say that Dr. McClain’s idea is “out of step with clear Scripture”? Well, AiG says:

Dinosaurs are land-dwelling animals. That means they were made on day six of creation (Genesis 1:24–25). Almost all birds are flying creatures to some degree, and they all have wings. Therefore, they most likely were all made on day five (Genesis 1:20–22). By saying or agreeing with the evolutionary claim that birds are dinosaurs or are most similar to dinosaurs, Dr. McLain is mixing groups made on different days of creation.

There are two really big problems with this statement. First and foremost, it ignores Scripture. Leviticus 11:13-19 lists the types of birds that are not to be eaten. What does that list end with? It ends with a BAT! So what Scripture calls a bird is not what modern people call a bird. Any unbiased look at Scripture indicates that when the Old Testament mentions birds, it is referring to all animals that fly, which includes certain mammals. Well, most mammals were made on day six, so Scripture itself mixes groups made on different days. Even AiG has to agree that bats are mammals. In addition, it must agree that whales are mammals. They are swimming creatures, which were also made on day five. Thus, Scripture says that some animals we call mammals were made on day five, while others were made on day six. If some animals we call mammals were created on day five and some on day six, why couldn’t some animals we call dinosaurs have been made on day five and others on day six?

The second problem here is that AiG even admits that all birds were “most likely” made on day five. If AiG has to hedge on its own statement about when all birds were made, how in the world can Dr. McLain’s idea be “out of step with clear Scripture”? AiG is actually admitting that the Scripture isn’t clear on this point. I think what AiG means is that Dr. McClain’s view is out of step with AiG’s interpretation of Scripture. In other words, AiG seems to be conflating its interpretation of Scripture with what clearly comes from Scripture. That’s a very dangerous path to go down!

AiG also has a problem with Dr. McClain’s view that at least some dinosaurs had feathers. This is extremely odd, since AiG has stated previously:

Nothing in the Bible precludes the erstwhile existence of feathered dinosaurs.

So which is it? Is the idea that some dinosaurs might have had feathers “out of step with clear Scripture,” or is there nothing in the Bible that “precludes the erstwhile existence of feathered dinosaurs”? Clearly, AiG’s second statement is the correct one. Why, then, is AiG complaining about Dr. McClain’s view?

In my previous post, I encouraged you to watch a 12-minute video from Dr. Todd Wood that clearly demonstrated AiG is not treating him fairly. In this article, I suggest you watch a 13-minute video to show you that AiG is not treating Dr. McClain fairly either.

If you watch other videos of Dr. McClain’s, you will see they are consistent with this video, which doesn’t contradict Scripture in any way.

Once again, I really appreciate Dr. McClain’s view on this. I have always been skeptical of the idea of feathered dinosaurs (see here, here, here, and here). However, as a young-earth creationist, I want to listen to those who have different viewpoints, especially those who are as well-versed in this issue as Dr. McClain. Based on my reading, Dr. McClain is the most qualified creation scientist to speak on the fossil record of dinosaurs. Whether or not I agree with him, I need to learn as much as I can from him. If AiG really wants to learn the truth about the details of how God created, it should try to learn from him as well!

One of the Oddest Ideas I Have Seen in a While

I have been exposed to a lot of odd ideas over the years: the flat earth, the idea that we never landed on the moon, chemtrails, etc. etc. Well, I can now add another to the list. This one comes from Answers in Genesis (AiG), which is warning Christians about the dangers posed by Young Earth Evolutionists. If you looked at those three words and said “What?”, I don’t blame you. Obviously, there is no such thing as a young-earth evolutionist. Evolution (at least in the sense most people use the term) requires billions of years, so if you are an evolutionist, you cannot believe in a young earth.

What does AiG mean by “young-earth evolutionist”? Apparently, it’s a young-earth creationist who is unwilling to pledge fealty to AiG’s tests of orthodoxy. Consider, for example, Dr. Todd Wood, who has a Ph.D. in biochemistry and was once the director of bioinformatics at Clemson University’s Genomics Institute. He is a committed Christian, a knowledgeable creationist who has done original research in the field, and an expert in baraminology, the scientific study of what kinds of living organisms were originally created by God. He believes (and teaches) that the days listed in Genesis 1 were roughly 24 hours long, that there was a worldwide Flood that is responsible for most of the fossil-bearing rocks we see today, and that the land animals we see today (with the possible exception of many kinds of insects) are descended from the animals that walked off the Ark after the Floodwaters receded. In short, he is a young-earth creationist.

Why does AiG call him a young-earth evolutionist? Because he is being honest about the data related to origins. For example, AiG takes issue with his famous statement that there are “gobs and gobs” of evidence for evolution. AiG doesn’t like this, because it claims that all this supposed evidence has already been “dealt with,” so none of it qualifies as actual evidence. While the first part of this statement is true, the second part is clearly not, and that goes to the core of the difference between AiG and many serious creation scientists. Yes, creationists have “dealt with” data that seem to support evolution. However, as any serious scientist understands (and AiG gives lip service to), scientific data require interpretation. Yes, creationists can interpret data in a way that is consistent with their ideas, but evolutionists can interpret that same data in a way that is consistent with their ideas. AiG seems to think that once creationists have figured out a way to interpret the data in a manner consistent with their ideas, the data no longer qualify as evidence for evolution. That is simply not true!

Anyone who has spent any significant amount of time seriously studying science understands that there is often no way to decide which interpretation of the data is correct. Often, one side’s interpretation of the data seems desperate, but that doesn’t mean it is wrong. Let me give you two examples. First, consider the GULO pseudogene. Evolutionists think that it is a broken version of a gene that was originally functional in early mammals, but mutations rendered it nonfunctional during the course of evolution. Well, the same mutations that are thought to have rendered it nonfunctional in apes are also found in humans. This is thought to be excellent evidence that humans and apes have a common ancestor whose gene had already been rendered nonfunctional, and that nonfunctional gene was passed on to both apes and humans. It’s true that the most straightforward way to interpret the GULO pseudogene is through the lens of common ancestry. Now, of course, there are ways to interpret it in the context of young-earth creation, and I give one of them in the link above. However, if you read it, you can see that it is not the most straightforward interpretation of the data.

Next, consider the phenomenon of homology. Many very different organisms share very similar features. All vertebrates (animals with backbones), for example, have the same basic plan for their forelimbs. Evolutionists assure us that this is because all vertebrates evolved from a common ancestor that passed on its forelimb plan to each of its descendants. In other words, homology is the result of common ancestry. However, there are many, many examples of similar structures that cannot be the result of common ancestry, because evolutionists have decided that those organisms don’t share a common ancestor that could give them that structure. As a result, they say that in such cases, homology is not a result of common ancestry. In other words, sometimes homology is a result of common ancestry, and sometimes it is not. That’s not a very straightforward interpretation of the data. A better interpretation of the data is that organisms were originally made by the same Designer, who simply used the same basic design over and over again when it was appropriate.

So….is the GULO pseudogene evidence for a common ancestor between apes and humans? Absolutely yes! Can creationists accommodate the GULO pseudogene in their view? Yes, but it seems a bit desperate. Is homology evidence for a common Designer? Absolutely yes! Can evolutionists accommodate it in their view? Yes, but it seems a little desperate. To any serious scientist out there, this shouldn’t seem strange. In every field where there are competing theories, those who support one theory have a set of evidence that is very strong, and those who support a competing theory have another set of evidence that is very strong. Typically, both sides can accommodate the other side’s evidence in their theory, but often, that accommodation seems desperate. Indeed, we often make decisions between scientific theories by deciding which one seems the least desperate when dealing with all the data!

Not only does AiG hate admitting that there is evidence for any view that disagrees with its own, it really hates the way Dr. Wood explains how he personally deals with the “gobs and gobs” of evidence for evolution. He says that he has faith. It’s rather odd for a creationist organization to argue against faith, but that seems to be what AiG is doing! It claims that in emphasizing his faith, Dr. Wood comes very close to fideism, which says that faith is opposed to reason. Of course, this is a gross mischaracterization of Dr. Wood’s views, and anyone who has honestly read Dr. Wood’s work understands that.

In fact, you don’t even have to honestly evaluate his work to see that AiG is mischaracterizing Dr. Wood’s views. You just have to go to YouTube and see his 12-minute video about why he is a creationist:

I really encourage you to watch the entire video, because it shows how a serious creationist honestly deals with evidence that seems to contradict his view (he specifically mentions one piece of data and vaguely refers to another). In case you do not, however, let me summarize what he says. Like any real scientist, he says that he is comfortable not having an answer to every question related to origins. As a result, his faith can remain strong despite challenges to it, which allows him to work towards finding answers to those challenges.

Now please note that I do not agree with everything Dr. Wood says. In fact, I disagree with his idea that there are “gobs and gobs” of evidence for evolution. Based on my interpretation of the data, I find that there is some evidence for evolution (which is why serious scientists can believe in it), but the “gobs and gobs” of evidence support the creationist view. However, I am also humble enough (despite what my students might say) to admit that I could be wrong. Thus, I value Dr. Wood and his contributions to creation science. In fact, I thank God for what he is doing!

Please note that AiG calls other very serious creation scientists “young-earth evolutionists.” I plan to address that in at least one more article.

Many Scientists Believe Scientific Theories Religiously

Many scientists believe the Big Bang Model religiously, not scientifically.
Those who understand the formation of our universe using the Big Bang model are forced to believe that the vast majority of the universe is made up of material about which scientists know absolutely nothing. As shown in the picture, to believe in the Big Bang model today, you must believe that all the matter involved in all the experiments done by all the scientists in history makes up only about 5% of the universe. 72% of the universe is composed of dark energy, a form of energy that was completely unknown until the 1990s and is so far undetectable and not understood at all. The other 23% is made of dark matter, which is matter that we cannot see because of the limitations of our experimental capabilities. Scientists have been trying to detect dark matter for decades, but so far, nothing has been found.

Why must those who are guided by the Big Bang believe that the vast majority of the universe has gone undetected? The Big Bang model predicted that over time, the expansion of the universe should be slowing down, since all matter is gravitationally attracting all other matter. However, data that started being collected in the 1990s indicate that in the past, the expansion of the universe was slower, which implies that the universe’s expansion is actually speeding up. The current amount of dark energy that is supposed to exist is what’s necessary to retrofit the Big Bang model to allow for this increase in expansion rate.

Belief in dark matter, on the other hand, is used to explain around certain observations that are surprising based on currently-accepted physics. For example, the way most galaxies rotate is not what is expected based on Newton’s Universal theory of Gravitation, but assuming a specific distribution of unseen matter, we can “fix” the galaxies so they rotate as expected. In addition, there are ways to indirectly determine the mass of galaxies, and those indirectly-determined masses usually don’t agree with the masses indicated by the matter that we can see in them. Thus, there must be unseen matter there.

On a personal level, I think dark energy exists only in the minds of those who are committed to the Big Bang Model. I see no serious evidence for its existence. Dark matter, on the other hand, has at least some serious evidence behind it. After all, either the physics we currently say we “know” is wrong, dark matter really exists, or something else that hasn’t been theorized exists to explain the discrepancies. Of course, as anyone who has read this blog for a while knows, I am just as likely to believe that the physics we currently “know” is wrong. As a result, I have always been intrigued by an alternate model of gravity called Modified Newtonian Dynamics (MOND). Its proponents claim that it can not only account for all the effects currently attributed to dark matter, but it has also made predictions which have later been confirmed by new data.

Well, one of its proponents recently wrote an article for The Institute for Art and Ideas. The title is simple and says it all: “Dark Matter Doesn’t Exist.” He goes through experimental evidences that support MOND, and he notes the failures of multiple searches for dark matter. While I am inclined to think that MOND is more likely to be true than dark matter, I am not convinced that it is the way to go. However, I did find this statement in his article very interesting:

We need to scientifically understand why the dark-matter based model, being the most falsified physical theory in the history of humankind, continues to be religiously believed to be true by the vast majority of the modern, highly-educated scientists. This is a problem for the sociological and philosophical sciences and suggests a breakdown of the scientific method.

While I am not sure that the dark matter hypothesis is “the most falsified physical theory in the history of humankind,” I wholeheartedly agree with him on the rest of his point. However, I would broaden his statement to include many other scientific theories, like evolution as a creation myth, the dogmatic belief that the earth is billions of years old, and the Big Bang model. One of the problems that exists in science today is that too many scientists believe these theories with a religious fervor. As a result, they tend to reject all the evidence that questions them. This, of course, holds back science.

While I don’t know if MOND is the correct answer to the question of why certain astrophysical observations are not consistent with currently-accepted physics, I can say that this particular MOND proponent has hit the nail on the head when it comes to a very big problem in today’s scientific enterprise!

Antievolution Views Are Global

The Anti-Evolution League at the Scopes Trial in 1925 (click for credit)

Over the years, I have documented a lot of ignorant statements made by someone who claims to be “The Science Guy” (see here, here, here, here, and here). However, the most ignorant statement I have ever heard Bill Nye utter is:

Denial of evolution is unique to the United States.

In several previous posts, I have reviewed how this statement is demonstrably false, but I was recently made aware of a peer-reviewed study that confirms this fact. Now, of course, I seriously doubt that any amount of data will change Bill Nye’s mind, since he doesn’t seem to use scientific data while forming his opinions. Nevertheless, I hope the data will be useful to others.

The study, published in the International Journal of Science Education, compared the views of Korean biology teachers to those of American biology teachers when it comes to evolution. It then did a literature review of studies done on science teachers in other countries. Before I discuss the specifics, let me give you their overall conclusion:

…it is clear that science teacher antipathy or ambivalence toward evolution is by no means a problem restricted to the USA

I am not sure they could make that any clearer. And note that since they call this a “problem,” they are clearly in Bill Nye’s camp when it comes to wanting everyone to genuflect at the altar of Darwinism.

The details of the paper are more interesting to me, however, because while they clearly show that many Korean biology teachers have doubts about evolution, those doubts are different from the ones held by American biology teachers. For example, when asked to evaluate the statement, “Much of the scientific community doubts if evolution occurs,” 52.4% of Korean biology teachers agreed, while only 6.3% of American biology teachers agreed. However, when given the statement, “The theory of evolution cannot be correct since it disagrees with the Biblical account of creation,” only 3.0% of Korean biology teachers agreed, while more than four times as many (12.1%) American biology teachers agreed. Similarly, almost three times as many Korean biology teachers as American biology teachers agreed that, “The theory of evolution is based on speculation and not valid scientific observation and testing” (36.3% versus 13.6%).

Now the group of Korean biology teachers studied was small – only 33 in total. However, data based group of 33 individuals is estimated to have a statistical error of about 17% (square root of 33 divided by 33), which means that when the percentages are close, you can’t tell if there really is a difference between the groups. For example, 75.0% of American biology teachers and 81.8% of Korean biology teachers agreed with the statement, “Evolution is a scientifically valid theory.” Those numbers are well within 17% of one another, so there is no way to know whether or not Korean biology teachers are more likely than American biology teachers to believe that evolution is a scientifically-valid theory. However, the differences noted in the previous examples are high enough to conclude that American and Korean biology teachers think differently when it comes to those questions.

If I look at the 20 questions the study asked Korean biology teachers and compare their answers to those of the American biology teachers, I am left to conclude that in Korea, biology teachers aren’t inclined to disagree with evolution based on religious ideas. They seem to disagree with evolution based on their understanding of the science that relates to it. I find that interesting, because that’s why I first doubted evolution as an origin story. I was an atheist who did not believe in evolution, because even as a young science student, I saw that evolution didn’t align with the data. To this day, if I were not a Christian, I would still not think that evolution is a valid explanation for origins, since the data speak so strongly against it.

About That New “Dragon Man” Fossil….

A fanciful imagining of what the person who left behind the skull being discussed in the article might have might have looked like. (image from the scientific paper)

The media is abuzz with a “new” fossil discovery. Consider, for example, this article, which says:

A new species of ancient human dubbed Homo longi, or “Dragon Man,” could potentially change the way we understand human evolution, scientists said Friday.

A reader asked me to comment on the discovery, which I am happy to do. Please remember, however, I am not a paleontologist nor a biologist, so my comments are clearly from a non-expert position. Nevertheless, I think I can add a bit of perspective that is sadly missing in most discussions of this fossil find.

First, while this fossil is just making the news, it is anything but new. As one of the three scientific papers written about it informs us, the skull was discovered in 1933 by a man who was part of a team constructing a bridge. He hid it in an abandoned well, apparently with the idea to retrieve it later. However, he never did. Three generations later, the family learned about the skull and recovered it. One of the scientists who wrote the papers learned about it and convinced the family to donate the skull to the Geoscience Museum of Hebei GEO University back in 2018.
So what’s “new” isn’t the discovery of the fossil; it’s the analysis contained in the scientific papers.

Of course, one part of the analysis tried to answer the question of how old the skull is. Two different radioactive dating methods were used (comparing the ratio of two thorium isotopes as well as comparing the ratio of one thorium isotope and one uranium isotope). As is typical with radioactive dating, the two different methods didn’t agree with one another, and even the same method gave different ages depending on where the sample was taken from the skull. In the end, the ages based on these analyses ranged from 62±3 thousand years old to 296±8 thousand years old. Based on many factors, the authors said that the youngest this fossil could be was 146,000 years old.

Before I move on, I want to use these data to highlight something I have discussed before. The numbers that follow the “±” sign represent what scientists call error bars. They are supposed to tell you the most likely range over which the measurement can actually fall. When you read “62±3 thousand years old,” that is supposed to mean, “62,000 years is the most likely date, but it could be as low as 59,000 years or as high as 65,000 years.” In fact, the actual date could be lower or higher, but the most likely range is 59,000 years to 65,000 years. Notice, of course, that these error bars are utterly meaningless, since the measurements ranged from 59,000 years old to 304,000 years. This is one of the many problems with radioactive dating. Error bars that are utterly meaningless are constantly reported, giving the illusion of a very precise measurement, when in reality, the measurement is anything but precise!

With the “measured” age of the skull out of the way, let’s discuss the main issue. The scientific papers, as well as the media reports, indicate that this is a new species of human. It doesn’t represent “modern” humans, and it doesn’t represent other known “archaic” humans. There is one big problem with this idea. The paper says that based on the characteristics of this skull, the human it represents is more closely-related to modern humans than is Neanderthal Man. The problem, of course, is that we know Neanderthal Man is fully human, because we know that Neanderthal Man interbred with modern humans. Thus, Neanderthal Man is from the same species as modern man. Since this skull indicates its owner is even more closely related to modern humans, it is a modern human as well.

So while this skull can tell us something about the variety that has existed among humans over the years, it tells us nothing about the “story” of human evolution. It simply represents another variety of human being.

Dismantled: A Scientific Deconstruction of the Theory of Evolution

Over the years, I have read (and met) several creation scientists for whom I developed great respect. For example, I consider Dr. John Sanford’s work to be not only brilliant, but also very important when it comes to understanding genetics and evolution. I have been fortunate enough to get to know him personally, and his keen intellect is overshadowed only by his deep devotion to our Lord. I personally think of him as a scientist on par with John Ray or Robert Boyle.

I recently got an email from him promoting a documentary entitled Dismantled: A Scientific Deconstruction of the Theory of Evolution. I am not a fan of documentaries, because they often devolve into propaganda pieces. However, since Dr. Sanford is featured in it, along with other creationist luminaries like Dr. Robert Carter, Dr. Georgia Purdom, and Dr. Nathaniel T. Jeanson, I decided to watch it.

Overall, I was quite pleased. I didn’t like the beginning very much (more about that in a moment), but once the documentary got into the serious science, I thought it did a very good job of communicating important truths about nature in a way that non-scientists can understand.

Early on, for example, it makes the standard (and important) distinction between microevolution and macroevolution. It discusses how dogs descended from wolves and then makes the point that this microevolution is well understood: It involves using selection to discard genetic information instead of producing new genetic information. This, of course, is the opposite of what is needed for macroevolution, the naturalist’s creation myth. To illustrate this fact, the documentary makes the point that you can selectively breed wolves to make Chihuahuas, but because of the loss of information required by the process, you cannot selectively breed Chihuahuas to make wolves. I have never heard it put quite that way before.

The documentary spends a lot of time on human evolution, looking at both the genetic issues and the fossil evidence. Dr. Sanford brings up the “waiting time” problem that he has done original research on, which shows that the genetic changes required to go from some ape-like creature to man would take much, much longer than the evolutionary timescale allows. The Laetoli footprints are discussed, as are many of the other fossil-related problems with human evolution. One of the best parts of this section is where Dr. Carter discusses how evolutionists ignore the measured mutation rates in populations because they aren’t consistent with evolutionary theory. Thus, they replace the known mutation rates with ones that have been calculated to be consistent with evolutionary theory.

Speaking of Dr. Carter, he has the best line in the documentary. Towards the end, he sums up the recent genetic evidence for mitochondrial Eve, Y-chromosome Adam, a human population bottleneck, etc. He discusses how evolutionists didn’t expect any of these things, but they are necessary if the Biblical account is true. He then says:

So what we’re seeing over time is that the evolutionary model is getting more Biblical.

While I had never thought of it that way, I completely agree!

Now before I end, I do want to point out that I strongly disagree with the first part of the documentary, which tries to claim that evolution isn’t really science; it’s history. As such, it’s not the same as the science that cures disease and makes Mars rovers, because it studies something that is not repeatable: the past. This is a very common assertion among creationists, but it is utterly false.

In fact, epidemiology has cured disease by studying the past. More importantly, the study of the past is definitely repeatable. We cannot repeat the past itself, but we can study the evidence related to the past, develop a hypothesis, and then test that hypothesis with more observations of the evidence related to the past. We can repeat such observations in different parts of the world, and if the hypothesis is repeatedly verified, it is just as scientific as a hypothesis about a medical procedure. A theory is scientific if it makes predictions that can be observationally verified. This is true whether the theory is about the past, present, or future.

Despite this glaring flaw, I do think the documentary is worth watching, especially if you need an overview of how the latest scientific discoveries support the creationist position.

NOTE: You can watch the documentary on Answers TV as part of a free trial and then see if you like Answers TV enough to continue the subscription.

Microscopic Analysis of Dinosaur Soft Tissue Casts More Doubt on Proposed Preservation Mechanism

The dark mass near the center is the cell body of a dinosaur bone cell. The various “arms” extending from the body are its filipodial extensions. (click for credit)
I have written a lot about soft tissue found in dinosaur fossils and other fossils that are supposed to be millions of years old (see here, here, here, here, here, and here, for example). Right now, the best work being done on this issue comes from the Dinosaur Soft Tissue Research Institute, which is run by microscopist and young-earth creationist Mark Armitage. Without the help of government grants, he and his colleagues have produced some truly incredible work. Their latest contribution was published in Microscopy Today, and it strengthens the case that these fossils cannot be millions of years old. As always, I encourage you to read the article in its entirety, but here is my “color commentary.”

First, the article shows more incredible, delicate structures that would not be expected to survive any preservation process that would protect them for millions of years. For the first time in the scientific literature, there are two excellent pictures of dinosaur vein valves (Figures 2 and 3), features that are so delicate they are hard to extract from animals that have just recently died. In another first, he shows a nerve from the same fossil (Figure 6). In that nerve, you can see the delicate Bands of Fontana, structures that are unique to nerves.

He also shows a bone cell from the same fossil (Figure 7). While bone cells from dinosaur fossils have been published in the scientific literature, this particular one is very important. Bone cells have characteristic structures called filipodial extensions that are remarkably thin (widths of less than 200 billionths of a meter). The bone cell shown in their study has a filipodial extension that is 24 millionths of a meter long. That doesn’t sound like much, but it is about 30% longer than any other dinosaur filipodial extension found in the literature. This is important, because its length is more than 100 times its width. Think about a structure with those dimensions made out of soft tissue. It would be ridiculously fragile, yet there it is in a dinosaur fossil!

Second, and more importantly, he shows that the current explanation evolutionists have for the preservation of soft tissue in dinosaur fossils doesn’t work. Dr. Mary Schweitzer was the first to give strong evidence for the existence of soft tissue in dinosaur fossils, but she is committed to an evolutionary view. As a result, she needs to find an explanation for how such tissue could survive for millions of years. Seven years ago, she published a study in which she hoped to show that iron from the blood of a dinosaur could produce certain reactions that would preserve the tissues. I wrote about her explanation at the time and how it didn’t seem to make sense based on what we knew. Later on, better chemists than I wrote a detailed analysis about how her explanation is inconsistent with the data.

This new paper demonstrates rather conclusively that Schweitzer’s explanation doesn’t work for the fossil being discussed. Armitage and his colleague (Jim Solliday) search the filipodial extensions of bone cells that are found right outside a canal that held a blood vessel. Since the cells are so close to what was a blood vessel, and since the filipodial extensions are so delicate, those iron-induced reactions should produce noticeable effects on the filipodial extensions. He shows that those effects are not present. Thus, it is unlikely that such reactions happened at all in the fossil.

Also, in her study, Schweitzer took great pains to prevent blood clotting so that iron from the blood could be distributed throughout the soft tissue she was trying to preserve. However, Armitage and Solliday present strong evidence for massive blood clotting in their fossil. This would prevent iron from being able to promote any tissue-preserving reactions. While their evidence is strong, however, it is not conclusive. Thus, as they suggest, more research needs to be done.

The Dinosaur Soft Tissue Research Institute is on the forefront of this issue in science, and they are doing it without the massive government grants available to organizations who are desperately trying to fit the data into an evolutionary framework. If you have the means, I suggest that you make a donation to keep science progressing in this area.

Did This Bird Go Extinct and Re-Evolve? I Doubt It.

A flightless Railbird on the Aldabra atoll in the Indian Ocean (click for credit)

Over the past few days, several people have sent me articles like this one, which makes a rather fantastic claim:

The Aldabra white-throated rail bird was declared extinct, a victim of rising sea levels almost 100,000 years ago.

However, the flightless brown bird has recently been spotted – leaving scientists scratching their heads as to how – and why – the species has come back to life.

What do you conclude from reading that? The article seems to be saying that no one had ever seen this bird before; it was only known from the fossil record. Now, however, living versions of it have been seen, and how they came back from extinction is a mystery. Unfortunately, like many “science news” stories, this one distorts the science to the point that it is deceptive and misleading.

The science that is being distorted comes from a study published last year. A responsible article that describes the study can be found here. While the study and the responsible article don’t distort the science, I do think the conclusion that they draw is not the only one consistent with the data.

Let’s start with the bird that is being discussed. It’s the Aldabra white-throated rail, whose scientific name is Dryolimnas [cuvieri] aldabranus. It lives on the Aldabra atoll in the Indian Ocean and is nearly identical to white-throated rails (Dryolimnas cuvieri) found in other parts of the world, like Madagascar. However, the ones on the Aldabra atoll cannot fly, while the others can. As a result, the flightless birds on the atoll are considered a subspecies of the version that can fly.

While we cannot say for sure, the generally-accepted origin story for the Aldabra white-throated rail is that normal white-throated rails landed on the atoll, and since there were no predators there, they stayed. Since they didn’t need to fly anymore, they evolved into flightless birds over several generations. This makes sense, because when a population of organisms doesn’t need a particular biological trait, mutations can degrade those traits without affecting survivability. In addition, DNA is so incredibly well-designed that over the course of generations, it can “turn off” genes that are no longer used in order to save energy. As a result, it makes sense that these flightless birds are descendants from birds that could originally fly.

Why do these articles discuss the birds being extinct at one point? Because the authors of the scientific study looked at the fossil record of the atoll. Using scientifically-irresponisble dating methods, they came to the conclusion that the atoll was completely underwater about 140,000 years ago. When they looked at fossils they interpreted to be older than 140,000 years, they found two bones that seem identical to the corresponding bones in the Aldabra white-throated rails that currently live on the atoll. Thus, they conclude that these flightless birds lived on the atoll before it went completely underwater.

Well, since the birds couldn’t fly, the authors assume that they all died when the atoll was underwater. However, in fossils that they interpret as being deposited after ocean levels decreased and the atoll was no longer underwater, they found another bone that looks similar to the corresponding bones in white-throated rails that can fly. However, it is heavier and more robust than what is found in those birds, but still lighter than what is found in the flightless Aldabra white-throated rails. In other words, it seems to be “in between” the bone of a normal white-throated rail and a flightless white-throated rail. To them, that gives “irrefutable evidence” (their words) that the Aldabra white-throated rails evolved twice: once before the atoll went underwater, and once after.

While their interpretation of the evidence makes sense and is consistent with all the known data, their case is certainly not “irrefutable.” First, you have to assume that they are interpreting the fossil record correctly. There is a lot of evidence to indicate the earth isn’t anywhere close to 140,000 years old, and if that evidence is correct, then their entire explanation is wrong. Also, even if the earth is as old as these scientists want to believe, the authors’ explanation is not the only one consistent with the data. We know that flightless animals can move from place to place on floating mats of vegetation. This is called “rafting,” and it is used by both evolutionists and creationists to explain the worldwide distribution of certain animals. If the atoll flooded like the authors think, the flightless birds could have survived by rafting. What about that one bone that is “in between” the two subspecies? There are natural variations in all bones. A “more robust” bone from a normal white-throated rail can be explained by natural variation within a population of normal white-throated rails.

The main reason I am writing about this is not to argue with the authors. It’s to point out the deceptiveness of articles like the one I quoted at the beginning of the post. As I have said many times before, do not believe the things you read in the popular press when it comes to science. Most “science journalists” are profoundly ill-equipped to understand science, and usually quite poor journalists as well.

A Bacterium That “Eats” Carbon Dioxide…and a Creationist Prediction

Escherichia coli (E. coli) are the workhorses of the bacterial world. They are found in every human being and most warm-blooded animals, but they are also found in laboratories all over the world. Because they are easy to care for, reproduce quickly, and have a genome that is reasonably well-understood, they are a popular subject of study among biologists. In addition, they end up producing a lot of chemicals that we need but are unable to produce ourselves. For example, insulin is a protein that all people need, but some people don’t make enough of it (or don’t respond well enough to it) to remain healthy. That leads to diabetes, and one treatment for diabetes is regular insulin injections.

While the insulin in pigs and cattle is close to what we find in people (and was used to treat diabetes for a long time), the best insulin for most diabetics is human insulin. Unfortunately, even with the best technology available, we aren’t good enough chemists to make insulin, but simple organisms like bacteria are. As a result, scientists have learned how to insert the human gene for insulin into a bacterium, which allows the bacterium to do the chemistry for us. As a result, much of the insulin used to treat diabetics today is human insulin produced by E. coli bacteria.

Unlike some species of bacteria, however, E. coli have to eat in order to get the energy and raw materials they need to do that chemistry. This ends up producing carbon dioxide as waste. To reduce the buildup of carbon dioxide in the atmosphere, then, it would be nice to produce chemicals like insulin from an organism that does not produce carbon dioxide in order to live. There are technical problems with that, however, so right now, diabetic insulin (and many other medically-related chemicals) adds to humanity’s “carbon footprint.” There are two ways to fix this: Either figure out how to use organisms that don’t have to eat (like organisms that make their own food through photosynthesis) or change E. coli so that it doesn’t have to eat.

In a recent study, scientists have been working on the second alternative and have experienced some success. As a byproduct, they have produced something that can be used to test creationism.

Another High-Profile Defection from Darwinism

Yale computer science professor Dr. David Gelernter (click for source)

The High Priests of Science continue to assure us that there is no debate when it comes to the validity of evolution as an explanation for the history of life. As the National Academy of Sciences says:

…there is no debate within the scientific community over whether evolution occurred, and there is no evidence that evolution has not occurred. Some of the details of how evolution occurs are still being investigated. But scientists continue to debate only the particular mechanisms that result in evolution, not the overall accuracy of evolution as the explanation of life’s history.

The problem, of course, is that such dogmatic statements are not consistent with the data that is supposed to guide scientific inquiry. When people honestly evaluate such data, many see how wrong the High Priests of Science are. Nearly two years ago, for example, I wrote about a world-renowned paleontologist who put up a display in his museum showing how there was no controversy about evolution. The problem, of course, is that he had never investigated all the data. When he got up the courage to actually read books written by scientists who point out the many flaws in evolutionary thinking, he ended up being convinced by the data and defected away from Darwinism. This cost him his job, but at least his scientific integrity remained intact.

Now there is another addition to the list of high-profile academics who had the courage to investigate all the data. His name is Dr. David Gelernter, and he is a professor of computer science at Yale University. In May of this year, he wrote a very interesting article for The Claremont Institute. I encourage you to read the article in its entirety, but I cannot help but add a bit of “color commentary.”
