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

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.

Another Confirmed Creationist Prediction

This was one of the first depictions of Neanderthal man, based on the work of paleontologist Marcellin Boule.

In 1908 a nearly-complete fossil skeleton was found in La Chapelle-aux-Saints, France. Marcellin Boule, professor at the Museum of Natural History in France and director of the French Institute of Human Paleontology, analyzed the skeleton in detail, eventually publishing his findings in the scientific literature. Before his scientific publication, however, a weekly French newspaper (L’Illustration) published the drawing above, which was based on Boule’s work. The drawing was later published in the Illustrated London News. As you can see from the drawing, Neanderthal man was interpreted to be a sub-human creature that was probably one of the steps in the hypothetical evolutionary process that led from an ape-like creature to modern humans.

As time went on, more discoveries were made that indicated this view was far from correct. Artifacts were found indicating that Neanderthal man buried his dead, used fire, made art, etc. This somewhat elevated Neanderthals from sub-human to almost-human. When DNA analysis strongly suggested that Neanderthals and what some call “modern humans” interbred, it became increasingly clear that from a biological point of view, Neanderthals were, in fact, fully human. Nevertheless, most evolutionists still consider Neanderthals to have lower intelligence than modern humans.

Throughout this entire time, creationists have seen Neanderthals as human in every way, including their intelligence. As early as 1925, creationist Harry Rimmer wrote a pamphlet entitled “Monkeyshines: Facts, Fallacies, and Fables Concerning Evolution.” In it, he says that drawings like the one given above are incorrect. He goes on to state:

At any rate, these reconstructions of the Neanderthal man do not show him the way his skeleton really was. He also was a true man.

This has been a common theme throughout the young-earth creationist literature. Neanderthal man was truly human in every sense of the word. A recent paper confirms this long-standing creationist prediction, while at the same time falsifying the evolution-inspired idea that Neanderthal man was of low intelligence. The paper analyzed a cord that was found on a stone tool which was made by Neanderthals. While the cord was not part of the stone tool, it was stuck to the tool and was deposited either before or with it. The authors show that the cord was made of three strands twisted around each other, which indicates sophisticated intelligence. As they say, it

“…is the oldest direct evidence of fibre technology to date. Its production demonstrates a detailed ecological understanding of trees and how to transform them into entirely different functional substances. Fibre technology would have been an important part of everyday life and would have influenced seasonal scheduling and mobility. Furthermore, the production of cordage implies a cognitive understanding of numeracy and context sensitive operational memory. Given the ongoing revelations of Neanderthal art and technology, it is difficult to see how we can regard Neanderthals as anything other than the cognitive equals of modern humans.

As I have said before, it is an exciting time to be a young-earth creationist. The true test of a scientific theory is confirmation of its predictions, especially when those predictions are at odds with a competing theory. In this case (and many others), young-earth creationism is showing that it is a robust, successful scientific theory.

The Inquisition Is Furious About Brazil!

Bill Nye says and writes a lot of ignorant things (see here, here, here, here, and here, for example). While it is hard to choose the most ignorant statement he has ever made, this one has to be in the top five:

Denial of evolution is unique to the United States.

I have already shown how that statement is 100% false, and anyone who even casually investigates the issue would know that it is false. However, as the links above show, investigation is definitely not one of Nye’s strong suits! I was reminded of his incredibly ignorant statement when I read this article, from the journal Science.

Like Bill Nye, the author of the article doesn’t seem to understand how to investigate an issue. Nevertheless, the article has some interesting content. It seems that the federal government in Brazil has appointed Dr. Benedito Guimarães Aguiar Neto to head an agency called CAPES, which oversees Brazil’s graduate study programs. This is noteworthy, because Dr. Neto was instrumental in forming an Intelligent Design Research Center at Mackenzie Presbyterian University in Brazil. Of course, this infuriates the Scientific Inquisition, because Intelligent Design has been officially declared as heresy by the High Priests of Science. To have someone who believes in heresy positioned in a powerful educational office is unthinkable! As the article tells us, one Brazilian biologist has said:

It is completely illogical to place someone who has promoted actions contrary to scientific consensus in a position to manage programs that are essentially of scientific training.

Of course, that very statement is incredibly anti-science, because almost all of the great scientific advancements in history come from the very act of questioning the scientific consensus. I would think that every institution of higher education should have many high-level officials who challenge the scientific consensus.

As I said, the author of the article doesn’t seem to be able to investigate an issue, since he calls Dr. Neto a “creationist.” I realize that the term is very broad, but there is no indication that Dr. Neto is a creationist. In fact, all he has stated is that Intelligent Design should be introduced in Brazil’s basic educational curriculum. I suspect that he is an advocate of intelligent design for that reason, but that doesn’t make him a creationist. Dr. David Berlinski is an advocate of Intelligent Design, and he doesn’t even believe in God. However, if you are a lazy writer, it is easier to falsely label a person than it is to actually investigate what that person believes.

In any event, I can’t help but see this as a step in the right direction. The progress of science depends on questioning the scientific consensus. Whether or not it was intentional, Brazil’s government decided to appoint someone who is skeptical of the consensus in a position of influence when it comes to science education. Not only does this further demonstrate that Bill Nye’s statement is breathtakingly ignorant, but it also gives us more indication that the biological sciences are slowly emerging from the quagmire of NeoDarwinism and getting ready to truly advance.

More Incredible Dinosaur Soft Tissue Results

The Dinosaur Soft Tissue Research Institute is producing some incredible results. About two months ago, I discussed a video in which the institute’s founder, Mark Armitage, showed some of them. Recently, Armitage posted another video that shows even more results, and once again, they are amazing.

If you don’t have time to watch the entire video, let me summarize what I consider to be the two most amazing things shown. In my previous post, I told you that Armitage shows delicate vein valves that he extracted from soft tissue found in a triceratops fossil. It is amazing that he could get them, since they are so delicate that I end up destroying them when I try to get them from a dissection. More importantly, there is no possible way that such a vein valve could be from any source other than the dinosaur, since no organism that could possibly contaminate the fossil produces such structures. Thus, these vein valves are clearly original tissue from the dinosaur itself.

At 2:49 in this video, he shows not only the vein valve, but he shows that the wispy tissue which covers the valve when it is close is still 100% intact! How does he do that? He traps bacteria underneath the closed valve. The tissue is so thin that you can actually see the bacteria swimming around underneath it, trying to get out! The bacteria are obviously the result of contamination, but there is simply no way that the vein valve can be explained that way. So the video shows incredibly delicate dinosaur tissue (so delicate that you can see through it) that is still soft! That’s strong evidence that the fossil is not millions of years old!

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

A false-color scanning electron microscope image of Escherichia coli. The different colors represent bacteria with different traits.

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.

Incredibly Fragile Dinosaur Soft Tissue

Two images of the delicate, one-way valves from veins. They were found in dinosaur soft tissue!
(Image copied from the presentation embedded below)

Mark Armitage and James Solliday at the Dinosaur Soft Tissue Research Institute have been doing some amazing work. On October 5th, Mr. Armitage presented their findings at Lower Columbia College. Apparently, he has not yet received the video of that presentation, so he kindly posted a quick overview of the content. To me, it is astounding:

While everyone should watch all 15 minutes of the presentation, I want to highlight the things that I think are most important.

At 2:29, he shows two images that elicited an audible gasp from me when I first saw them. To understand just how incredible the images are, you need to know that there are one-way valves found in vertebrate veins. This is because the blood pressure in a vein is so low that blood can actually travel backwards. To prevent that, there are delicate, one-way valves throughout the veins. They open when the blood is flowing the correct way, and they close to prevent it flowing backwards. In the left-hand part of the image at the top of the post (copied from the presentation), you see a circle with what looks like a partially-opened tent flap. The circle is the base of the valve, and the “tent flap” is the delicate membrane that opens and closes. In that image, the valve is partly open. On the right-hand side, the valve is fully open.

This is incredible to me, because I have tried to dissect animals and extract these valves. I have never been able to. They are so delicate that I end up destroying them in the dissection process. Now, of course, I am not much of a biologist, and I am even less of an expert at dissection. Nevertheless, my experience with them indicates that they are absurdly delicate. Yet, here they are in a dinosaur fossil! Not only does this give evidence that the fossil is not millions of years old, but it also shows that these are definitely not structures that come from fungi or bacteria which recently invaded the fossil. Bacteria and fungi do not build structures with these delicate, one-way valves! He also presents other evidence that rules out bacterial and fungal contamination.

At 8:22, he shows red blood cells from a fossil that is supposed to be 400 million years old! The cells have the appropriate size and shape for red blood cells. Later on (12:05), he shows a blood vessel from a dinosaur fossil that has not even collapsed! It has an air bubble in it. When he does a stain test to see what is in the blood vessel, the test indicates that there is RNA in the blood vessel!

At 6:47, he shows what appears to be blood clotted in the tissue. He shows how it behaves just like you would expect blood to behave when exposed to polarized light, and he also shows that iron from the blood has not spread into the bone tissue. This is important, because Dr. Mary Schweitzer has proposed that iron might be preserving the soft tissue found in dinosaur bones. There has already been several arguments (see here and here) that seem to invalidate Dr. Schweitzer’s hypothesis, but this observation is the nail in the coffin. Iron can’t be preserving bone tissue if it doesn’t spread into the bone to begin with!

I have said this before and will say it again: It’s a wonderful time to be a young-earth creationist!

NOTE: A commentor made the great suggestion that I post a link if you want to support Mr. Armitage’s research. Here it is:

This “Junk DNA” Confirms a Creationist Prediction!

How DNA is arranged in the nucleus of a cell when it’s not in the process of reproducing. (click for credit)

When a scientist refuses to see the design that is so obvious in nature, it can lead to all sorts of incorrect conclusions. Consider, for example, transposable elements in DNA. Often called “transposons,” they jump around in an organism’s genome. In other words, they are in different places in different cells of the same organism. Those who have their naturalist blinders on initially thought that they were useless – part of the “junk DNA” that represents all the evolutionary “flotsam and jetsam” that has accumulated over hundreds of millions of years. Dr. Leslie Pray, writing in Nature Education, puts it this way:

Transposable elements (TEs), also known as “jumping genes” or transposons, are sequences of DNA that move (or jump) from one location in the genome to another. Maize geneticist Barbara McClintock discovered TEs in the 1940s, and for decades thereafter, most scientists dismissed transposons as useless or “junk” DNA. McClintock, however, was among the first researchers to suggest that these mysterious mobile elements of the genome might play some kind of regulatory role, determining which genes are turned on and when this activation takes place.

Of course, we now know that these supposedly useless stretches of DNA have widespread functionality throughout the genome. However, a recent study demonstrated that one set of transposable elements (the HERV-H subfamily) has a particularly interesting function, which indicates that a creation scientist’s prediction I wrote about nine years ago has been confirmed.

Cool Video of a Soft Dinosaur Cell

(Images copyright Mark Armitage. Click for source)

A couple of years ago, I wrote about the remarkable dinosaur research being done by microscopist Mark Armitage. The story discussed two scientific articles he wrote about finding soft dinosaur cells in a Triceratops fossil. Well, Armitage is continuing his research at the Dinosaur Soft Tissue Research Institute in the state of Washington. The pictures above represent some new results: soft bone cells from a Nanotyrannus fossil.

Now whether or not there is such a thing as a Nanotyrannus is actually a matter of debate. Some paleontologists think the fossils are really from a juvenile Tyrannosaurus. So it might be a different species, or it might just be a juvenile form of an already-known species. Regardless of which is correct, it is well accepted that these fossils have been found in Cretaceous rock that is supposed to be about 65 million years old. It’s hard to understand how any cellular material could have survived for that long without being fossilized. Nevertheless, the cells that Armitage has extracted from the fossil are soft, as shown in the video below.

Of course, it is always possible that the cell is not really from the dinosaur. However, that’s a bit hard to believe. It came from a bone, and it has all the visual characteristics of an osteocyte, which is a bone cell. I can’t think of any possible contaminant that has the size, shape, and filipodial extensions that you see in the video. Also, remember that Armitage previously extracted soft bone cells from a Triceratops fossil. Thus, if this is a contaminant, it must be common to two completely separate fossils (or somehow introduced by Armitage’s process, which once again, is hard to believe).

I think it is reasonable to conclude that Armitage is, indeed, isolating soft dinosaur bone cells. He plans to make a presentation at Lower Columbia College in Longview Washington, on October 5th 2019, at 7 pm. In that presentation, it looks like he will also discuss how the soft tissues from which his cells are isolated react to stains for DNA and RNA. I won’t be able to make it, but I sincerely hope that it is recorded and that Armitage eventually writes another article about his continuing research!

One Way To See How Special Earth Is

A sample of the exoplanets “conservatively” thought to be in their star’s habitable zone, along with familiar planets for scale. (click for credit)

Thirty-five years ago, Dr. Theodore P. Snow wrote a book entitled Essentials of the Dynamic Universe. On page 434 of the 1984 edition, he summed up the obvious consequence of the idea that earth was formed as a result of natural processes without any need for Divine intervention:

We believe that the earth and the other planets are a natural by-product of the formation of the sun, and we have evidence that some of the essential ingredients for life were present on the earth from the time it formed. Similar conditions must have been met countless times in the history of the universe, and will occur countless more times in the future.

In other words, there is nothing special about the earth; it is one of many planets that harbor life. The more we learn about the universe, the more we should realize just how mediocre the earth is.

Since Dr. Snow penned those words, almost 4,000 exoplanets (planets outside our solar system) have been discovered. How many of them are similar to earth? The most reasonable answer, based on what we know right now, is zero. Why? Well, let’s consider one and only one factor: whether or not the planet is in the habitable zone of its star. That’s the distance from the star which allows the planet to get enough energy to stay warm enough to support life as we know it.

Out of nearly 4,000 exoplanets, how many are within the habitable zone? With the recent discovery of a planet charmingly known as “GJ 357 d,” the number of planets that might possibly qualify is 53. If we are conservative in our estimate, the number drops to 19, but let’s be as optimistic as possible. Out of nearly 4,000 exoplanets, only 53 might possibly be in the habitable zone.

What do I mean when I say “might possibly be in the habitable zone?” Well, there are a few factors that influence a planet’s temperature, and the distance from its star is only one of those factors. Another important issue is the planet’s atmosphere. With the right mix and right amount of greenhouse gases, a planet that is a bit far from its star could be in the habitable zone, because even though it gets only a little energy from its star, its atmosphere holds onto that energy really well. In fact, that’s why GJ 357 d might possibly be in the habitable zone. It gets about as much energy from its star as Mars does from the sun, but it is massive enough to hold on to a pretty thick atmosphere. It’s possible that the atmosphere could make up for its distance from the sun, so astronomers say it is possibly at the “outer edge” of the star’s habitable zone.

Now think about that for a moment. If we consider only one factor necessary for a planet to sustain life (being in the habitable zone of a star), just over 1% might possibly have it. Of course, there are lots of other factors necessary for life as we know it. A life-sustaining planet must also have an abundance of water, the right mixture of non-greenhouse gases in its atmosphere, the right mix of chemicals in its crust to provide nutrition to organisms, a shield from both ultraviolet rays and cosmic rays that come from the star around which it orbits, a reasonable speed of rotation around its axis, etc., etc. The earth has all these things, but a survey of nearly 4,000 exoplanets shows that just over 1% have only one of those things. What’s the chance that one of those planets has everything else it needs to support life? The most reasonable answer based on what we know is zero.

Despite what naturalists expect (and most still want to believe), it is clear that the earth is a very, very special planet. One might be so bold as to say that it is the Privileged Planet.

Even Eyes Contain Bacteria!

Mouse eyes were studied in the article being discussed, but the results are probably applicable to many mammal eyes.

Writing about coral in the Journal Science, paleontologist Dr. George D. Stanley noted:

Symbiosis is the most relevant and enduring biological theme in the history of our planet.

If you aren’t familiar with the term, “symbiosis” refers to organisms of different species living together. There are three general forms:

(1) Parasitic symbiosis, in which one organism benefits and the other is harmed

(2) Commensal symbiosis, in which one organism might benefit but neither is harmed

(3) Mutualistic symbiosis, in which all organisms in the relationship benefit

I have written extensively on mutualistic symbiosis (see here, here, here, here, here, here, here, here, here, and here, for example). Not only does it fascinate me, but it was also the major scientific issue that led me away from atheism. When one sees the amazing mutualistic relationships that exist all over nature, it becomes clear that these organisms were designed to work together.

Bacteria tend to develop a lot of mutualistic relationships. Indeed, you would not be nearly as healthy as you are if it weren’t for the many mutualistic bacteria that live in and on your body. And while it is widely-known that you can find mutualistic bacteria in many parts of a mammal’s body, it was thought that you would never find them living in the eye for any extended period of time. That’s because mammal eyes contain an enzyme called lysosyme, which kills bacteria. However, new research indicates that at least one species of bacterium, Corynebacterium mastitidis, makes its home in at least some mammal eyes.
