Kraken man is back

He’s persistent, I’ll say that for him. I first encountered Mark McMenamin as an enthusiastic promoter of Stuart Pivar’s inflatable donut model of development. He then sank from sight, along with the pretentious septic tank salesmen, until two years ago, when he presented piles of ichthyosaur vertebrae as evidence that a giant cephalopod, a kraken, had been creating Mesozoic art by arranging the disks into a self portrait.

You may laugh now.

He presented at the Denver GSA meeting this year. Here’s his abstract.

THE KRAKEN’S BACK: NEW EVIDENCE REGARDING POSSIBLE CEPHALOPOD ARRANGEMENT OF ICHTHYOSAUR SKELETONS

MCMENAMIN, Mark A.S. and SCHULTE MCMENAMIN, Dianna L., Geology and Geography, Mount Holyoke College, South Hadley, MA 01075

In 2011, we hypothesized that extremely large Triassic cephalopods may be responsible for certain anomalous aspects of an unusual assemblage of giant ichthyosaur skeletons in the Luning Formation of Nevada. The hypothesis has been criticized by researchers who do not accept the ichnological evidence suggesting that the skeletons were deliberately arranged rather than being deposited by currents.

Hydrodynamic considerations regarding the probability of displacement (PD) of ichthyosaur vertebral centra arrays (n=12) show that three different biserial arrangements have PDs of 17%, 89% and 100% respectively by currents strong enough to displace a single centra. The critical Specimen U array at Berlin‑Ichthyosaur State Park has PD=~100, indicating that it is highly unlikely that the biserial pattern was imparted by submarine currents. The unwinnowed wackestone matrix confirms that competent water velocities did not frequently occur in this deep-water depositional environment. The Luning Formation also hosts Protopaleodictyon ichnosp. and supergiant amphipods.

We recently obtained photographs of a retired exhibit formerly on display at the University of Nevada, Las Vegas, Museum of Natural History. The display reconstructed a well‑preserved Shonisaurus skeleton as it was found in the field. The exhibit is well documented by photographs from a variety of vantage points. The skeleton appears to have been partly disassembled during the Triassic, and a biserial array of centra very similar to the Specimen U array occurs adjacent to the nearly complete skeleton. The UNLV array has a PD=~100, again indicating that the biserial pattern was not the result of current assembly. Finally, at least three of these centra show what may be triangular bite marks removed from their margins.

His latest evidence consists of a second array of vertebrae in a line (that’s right, his earlier remarkable claim was based on a single example of bones in a line), and he is also claiming that a non-random arrangement of the bones can only be explained by an intelligent cephalopod, with no other natural processes possible.

Furthermore, as the Huffington Post credulously (their only mode) reports, he has additional evidence in the form of a giant fossilized beak. Here it is:

krakenbeak

It’s a fragmented, unidentified chunk of rock, a few inches long, which he extrapolates by comparison to a Humboldt squid beak he bought on eBay to be the tip of a giant beak belonging to a squid that was between 50 and 100 meters long.

That’s it. When ichthyosaurs decay, their vertebrae tend to fall in a line, and here’s a broken rock that kinda vaguely looks like a bit of a beak, and from this he builds this elaborate fantasy of a giant kraken roaming Triassic seas crushing ichthyosaurs to death and then sculpting their bones into squid pictures.

He should go back to praising balloon animals.


Whoops. I neglected to mention another indictment of his rationality: McMenamin is a “devout Christian” who also believes in Intelligent Design creationism.

My name is Mark McMenamin. I have completed a PhD on the fossils of the Cambrian Explosion, have published several books on the subject, and am a devout Christian. At the present time I am actively researching the latest fossil discoveries from Cambrian boundary strata.

ENCODE has its defenders!

You know I was really pissed off at the crap ENCODE was promoting, that the genome was at least 80% functional and that there was no such thing as junk DNA. And there have been a number of better qualified scientists (like W. Ford Doolittle and Dan Graur and many others) who have stood up and registered their vehement disagreement with that nonsense. But there are some who agree that the genome must be largely functional, like John Mattick. Larry Moran reminds me that Mattick is the author of this infamous chart, however, which is best known as the original Dog’s Ass Plot.

Worst evolution diagram ever

That is so misleadingly dishonest it takes my breath away — Mattick cherry-picked genome sizes to fit his curve. One of my cell biology labs involves teaching students how to properly construct a simple graph, and I think I’m going to include this figure as a bad example.

Well, Mattick has done it again. He has published a paper (how do these things get through peer review?) disputing the existence of large quantities of non-functional DNA, which is largely an attempted rebuttal of Graur’s paper. It’s a short paper, but painful in its contortions and extraordinarily poor arguments. Larry Moran has done an excellent job of tearing it apart — I think he needs to polish it up and get that published.

The worst part of the paper, though, is the concluding paragraph — you know, where most of us try to put the most important message of the work.

There may also be another factor motivating the Graur et al. and related articles (van Bakel et al. 2010; Scanlan 2012), which is suggested by the sources and selection of quotations used at the beginning of the article, as well as in the use of the phrase “evolution-free gospel” in its title (Graur et al. 2013): the argument of a largely non-functional genome is invoked by some evolutionary theorists in the debate against the proposition of intelligent design of life on earth, particularly with respect to the origin of humanity. In essence, the argument posits that the presence of non-protein-coding or so-called ‘junk DNA’ that comprises >90% of the human genome is evidence for the accumulation of evolutionary debris by blind Darwinian evolution, and argues against intelligent design, as an intelligent designer would presumably not fill the human genetic instruction set with meaningless information (Dawkins 1986; Collins 2006). This argument is threatened in the face of growing functional indices of noncoding regions of the genome, with the latter reciprocally used in support of the notion of intelligent design and to challenge the conception that natural selection accounts for the existence of complex organisms (Behe 2003; Wells 2011).

I’m sure the Discovery Institute staff are dancing in pirouettes of joy at getting a neutral or possibly favorable mention in a legitimate journal. It’s not clear exactly what Mattick is trying to do here (lack of clarity is also a sin in science writing, let me remind you): either he’s trying to pre-emptively slander his critics by impugning them with an ideological motive, or he’s granting credence to Intelligent Design creationism. I’m inclined to think it’s both; he’s clearly trying to argue with the motives of Graur and others, but also, he’s claiming, as the creationists do, that evidence of function for the highly variable component of our genome is a de facto argument for a purpose for that variation, and that evolutionary theory does not support the idea of a functional purpose for variation in the sequence of most satellite DNA, for instance.

But I would not argue that ubiquitious functionality is unlikely because it has consequences for our theories; it’s wrong because of all the evidence that has been marshaled that most DNA is not there to serve a specific, selectable purpose for us humans.

Musings from the mind of a mouse

Casey Luskin is such a great gift to the scientific community. The public spokesman for the Discovery Institute has a law degree and a Masters degree (in Science! Earth Science, that is) and thinks he is qualified to analyze papers in genetics and molecular biology, fields in which he hasn’t the slightest smattering of background, and he keeps falling flat on his face. It’s hilarious! The Discovery Institute is so hard up for competent talent, though, that they keep letting him make a spectacle of his ignorance.

I really, really hope Luskin lives a long time and keeps his job as a frontman for Intelligent Design creationism. He just makes me so happy.

His latest tirade is inspired by the New York Times, which ran an article on highlights from the coelacanth genome. Luskin doesn’t think very deeply, so he keeps making these arguments that he thinks are terribly damaging to evolution because he doesn’t comprehend the significance of what he’s saying. For instance, he sneers at the fact that we keep finding conserved elements in the genome, because as we all know, there are lots of conserved elements.

Hox genes are known to be widely conserved among vertebrates, so the fact that homology was found between Hox-gene-associated DNA across these organisms isn’t very surprising.

I have to disagree with Jerry Coyne

Ball State University has a crap course on their curriculum: they have a crank professor, Eric Hedin, who is pushing religion and creationism in the guise of an astronomy course. It’s bad science and bad teaching, and I think Coyne has adequately document the abysmal quality of the material. It’s all religious apologetics and intelligent design creationism. I’m not going to disagree with that at all, and Ball State ought to be acutely embarrassed.

Unfortunately, this part of Coyne’s disagreement is invalid.

This has to stop, for Hedin’s course, and the University’s defense of it, violate the separation of church and state mandated by the First Amendment to the U.S. Constitution (“freedom of religion”) and which has been so interpreted by the courts. It’s religion taught as science in a public university, and it’s not only wrong but illegal.  I have tried approaching the University administration, and have been rebuffed.

This will now go to the lawyers.

No, sorry, not right — academic freedom is the issue here, and professors have to have the right to teach unpopular, controversial issues, even from an ignorant perspective. The first amendment does not apply; this is not a course students are required to take, and it’s at a university, which students are not required to attend. It’s completely different from a public primary or secondary school. A bad course is an ethical problem, not a legal one. It’s also an issue that the university has to handle internally.

This kind of thing happens. I’ve known of a couple of cases where faculty go ’round the bend and start flaking out in the classroom, and there’s not much you can do, except what Ball State seems to be doing. Put the person into low level service courses where they have to teach students something basic, like algebra, where their weird views can’t do much harm. Or give them some non-majors elective where they aren’t going to have much influence. I notice in Hedin’s courses that he’s only teaching low level courses and honors/interdisciplinary courses. It looks like maybe the department is doing their best to isolate a problem.

Another option is to take this history into consideration in tenure decisions. Hedin is an assistant professor, and so is probably untenured — the department may be avoiding confrontation until it gets dealt with decisively in Hedin’s tenure year.

If you’ve got a tenured professor who has gone weird on you, it’s a bigger problem…then you’ve got damage that needs to be routed around. Check out Michael Behe’s class schedule at Lehigh, for instance. It looks to me like they’ve carefully placed him only in courses where his ignorance about evolution won’t hurt too much. Are we going to sue Lehigh to get him fired? That won’t work, and is also an insult to a department that is doing their best with a bit of deadwood.

I think it’s very unwise for an atheist professor to pursue legal action against another professor for their religious views. That’s a two-edged sword, and if a university were to cave to public pressure to fire a professor for unpopular views, you know who’d be next.

Now it is possible that the whole physics department at Ball State is full of credulous nitwits who are trying to build a theological perspective into their curriculum. That will be corrected in two ways: they’re going to have a more difficult time hiring good faculty, and as the reputation of their department spreads, they’re going to have a more difficult time recruiting good students. Rot expands, you know. It’s not a good thing to encourage.

But it’s probably premature to threaten a department with legal action for having one dingbat assistant professor.

The Discovery Institute’s mask just slipped a bit more

That ghastly collection of homophobes and right-wing zombies, Focus on the Patriarchy, is starting a new initiative to take on the happily growing army of student atheists. They’re launching a series of ‘edgy’ videos called True U which feature grim Christians staring glumly at the camera while statistics scroll by (“Increasing numbers of college students are losing their faith!” “60% of all biology & psychology professors are atheist or agnostic!” Cheer up kids, it’s good news all the way!). Then to inspire them, they cut to a Christian fake college professor ranting away.

The ‘professor’ is…Stephen Meyer of the Discovery Institute! And the great thing is that he’s openly using the arguements of Intelligent Design creationism to counter atheism with assertions that science supports the existence of a god.

“The new atheism is the old atheism repackaged to make best sellers,” says Dr. Stephen Meyer, a presenter in the video, “but is completely out of touch with the most current developments in science.” Meyer, who holds a Ph.D. from Cambridge University in the History and Philosophy of Science, is a Senior Fellow at the Seattle-based Discovery Institute, an organization that promotes intelligent design. The Discovery Institute is behind the “Teach the Controversy campaign” that aims to teach creationist anti-evolution beliefs in United States public high school science courses alongside accepted scientific theories, claiming that a scientific controversy exists over these subjects.

It’s been settled for a long time, but this is one more nail in the coffin: Intelligent Design is simply a front for religious pitchmen. And not just any religion, but far right Christianity.

Also, his arguments are awful.

“When we find information in DNA molecules encoded in digital form, the best explanation is that that information also had an intelligent source.”

That’s what he babbled about endlessly in his dreary text, Signature in the Cell: nothing but rank assertions that genetic information is digital (really, it’s not), that it’s just like computer programs (nope), that computer programmers write computer code (OK, I’ll accept that), and therefore, there had to have been a Great Intelligent Space Programmer at the beginning of everything (can you say logic error, boys and girls? I knew you could). So now you know the next step, the part he wasn’t brave enough to say in his book…and that Super Programmer is Jesus.

At least I suspect that classroom is as fake as the one Ben Stein was yelling at in Expelled, since Meyer is no longer affiliated with any real university and spends all of his time flogging lies to his creakily fanatical colleagues and church audiences any more.

Bobby Jindal opened his mouth again

He was asked about education. He replied with a tired creationist excuse.

Bottom line, at the end of the day, we want our kids to be exposed to the best facts. Let’s teach them about the big bang theory, let’s teach them about evolution, let’s teach them — I’ve got no problem if a school board, a local school board, says we want to teach our kids about creationism, that people, some people, have these beliefs as well, let’s teach them about ‘intelligent design.’

The first sentence is sort of OK — yes, let’s teach the best ideas, the best evidence, the best science, the facts as we know them, and that includes good science like evolution and the big bang. But what Jindal then throws up as examples are bad science, claims without evidence, bad ideas that are contradicted by the evidence. Creationism and Intelligent Design Creationism are not the “best facts”, they don’t even cut it as “adequate facts” — they are bad and they are non-facts.

Can Jindal not tell the difference?

And since when is good education about teaching kids what their less-well-educated parents want them to know? How about if we teach them the truth, instead?

More lies from the Discovery Institute

Oh, christ. Another book is coming from those frauds at the DI, Darwin’s Doubt: The Explosive Origin of Animal Life and the Case for Intelligent Design. It’s Stephen Meyer’s unqualified, incompetent take on the Cambrian explosion.

Casey Luskin has already given us three reasons we’re supposed to buy it. 1) It’s going to contain the best arguments for intelligent design creationism EVAR; 2) it’s going to be packed full of reviews of the work of the “ID research community”; and 3) we’re living in a “post-Darwinian world”, where all the evolutionary biologists are already deserting the sinking ship of neo-Darwinism. Those aren’t reasons to buy the book; those are reasons the book is going to be total crap.

And why should you read it anyway? You want to know about the Cambrian, read books by real scientists. They’re out there already. One excellent resource is James Valentine’s On the Origin of Phyla; it is not light reading, but if you want to know about the paleontology and systematics of the invertebrate phyla of the Ediacaran and Cambrian, it really is the book to read.

And then to my surprise, while I was digging up the link to that book, I discovered that Douglas Erwin and James Valentine have a new book out as of January: The Cambrian Explosion: The Construction of Animal Biodiversity, which the reviews say is less technical than the Phyla text, but highly rated as an excellent overview. I can’t say I’ve read it yet, but I instantly ordered it.

I think it might be an interesting summer project to compare Erwin & Valentine side-by-side with Meyer. Well, “interesting” in a Bambi Meets Godzilla sort of amusing sense.

But if you want to know what caused the Cambrian explosion, I can give you the short answer. Not intelligent design; that doesn’t even make sense. What it was was environmental changes, in particular the bioturbation revolution caused by the evolution of worms that released buried nutrients, and the steadily increasing oxygen content of the atmosphere that allowed those nutrients to fuel growth; ecological competition, or a kind of arms race, that gave a distinct selective advantage to novelties that allowed species to occupy new niches; and the evolution of developmental mechanisms that enabled multicellular organisms to generate new morphotypes readily. Read the real books if you want to know more, and ignore the uninformed babble the charlatans of the DI will try to sell you.


By the way, Joe Felsenstein is asking for help: he’d like suggestions for what Stephen Meyer ought to have in his book.

Happy 9th Paul Nelson Day!

It’s a dying holiday, I’m sorry to say — I completely forgot it last year. But I was reminded this year, so I’ll mention it again. I think the proper way to celebrate it is simply to laugh at a creationist today.

The source of the holiday is a remarkable exhibition from Paul Nelson, who like several other creationists, loves to register and present at legitimate science conferences. The barriers are low, and many conferences are intended to give students an opportunity to present, so you’ll often find that all you have to do is send in a fee and an abstract and you’ll be allowed to put up a poster in an allotted space for a few hours of time. So Nelson showed up at the Developmental Biology meetings in 2004 with a poster titled “Understanding the Cambrian Explosion by Estimating Ontogenetic Depth” in which he and Marcus Ross claimed to have been collecting data measuring some parameter called “ontogenetic depth” in various organisms.

I was at that meeting. I asked him about that in person, and also in blog posts afterwards. How do you measure ontogenetic depth? Share your procedure so I can assess and replicate it, which is what scientists are supposed to do. He hemmed and hawed and hmmphed and in typical Nelsonian fashion babbled and burbled on, and the upshot was that he couldn’t tell me just then, but he had something he was writing and he’d polish it up and get it to me the next day, 7 April. He didn’t. We’ve been watching the 7th of April pass by for nine years now.

I think he’s felt the sting of mockery. In 2010 he announced that my criticisms were invalid, but he was inventing Ontogenetic Depth 2.0, which still isn’t defined and still doesn’t have a procedure.

In 2011 he posted some more essays on his fictitious method, in the first of which he announced that ontogenetic depth is A Biological Distance That’s Currently Impossible to Measure. Yeah? So why was he presenting a poster at a serious scientific meeting in which he and his colleague claimed to have been measuring it? Sounds like scientific fraud to me.

But then, Intelligent Design creationism has been scientific fraud all along, so I guess he was just following hallowed tradition.

Whoa, Missouri…you’re not going to let this one pass, are you?

Have you seen Missourie House Bill 291? Wow, it’s pushing intelligent design, um, boldly. Like a gibbon that just sat down in a pool of sriracha sauce in a big tub of feces, that kind of “boldly”.

It starts by defining evolution in one paragraph, and by evolution we mean just common descent. It says nothing specific about mechanisms or evidence, and is most concerned that evolution denies “operation of any intelligence, supernatural event, God or theistic figure”. And then we get 12 paragraphs defining Intelligent Design, which consist mainly of pointing to biological processes and phenomena and claiming that they are the result of intelligence.

I only point out the disparity in the length of the treatments to contrast it with one of the major demands of this law: equal treatment.

(6) “Equal treatment”, the approximate equal teaching of each specified viewpoint for a single course of instruction in course textbooks as follows:

(a) Course textbooks contain approximately an equal number of pages of relevant material teaching each viewpoint. Textbook materials include text, pictures, illustrations, graphs, tables, questions, discussion items, student exercises, teacher support material and other material supplied with the textbook, with freedom allowed the textbook publishers to arrange, substitute, or size material to provide an approximately equal teaching of each viewpoint for a specific textbook;

(b) In the absence of course textbooks which provide equal treatment, written interim material may provide alternate viewpoints, with interim textbook material developed pursuant to subsection 6 of this section as a recommended source;

No credible science textbook on the planet meets those requirements, and they’re just plain silly. Even setting aside the content, the scientific community is churning out hundreds of papers on evolutionary biology every week, we have a million scientists in biology, while Intelligent Design creationism is a fringe idea producing virtually no results of any worth, virtually no publications (and most of what they’ve got are in house journals, hothouse environments set up to protect their work from criticism), no data, no signficant complexity that needs careful pedagogical explanation—yet they’re demanding equal page counts in our textbooks?

I’m looking at our current introductory biology textbook, Life, by Sadava, Hillis, Hiller, and Berenbaum. Not counting the appendices and index, it’s 1259 pages long, it’s saturated with evolutionary biology, and it doesn’t say anything at all about intelligent design. So those authors had better get to work and make it 2518 pages long, half of it fluff, to satisfy a Missouri crackpot? Who gains from that? (Well, the textbook publishers would, I suppose.)

Their demands are also contradictory. Here’s their definition of “standard science”, which must be taught:

3. All science taught in Missouri public elementary and secondary schools, including material concerning physics, chemistry, biology, health, physiology, genetics, astronomy, cosmology, geology, paleontology, anthropology, ecology, climatology, or other science topics shall be standard science. All standard science course materials and instruction shall meet the following criteria:

(1) If empirical data is taught, only such data which has been verified or is currently capable of being verified by observation or experimentation shall be taught. Data with the appearance of empirical data which has never been verified and is currently incapable of being verified shall be identified as nonverifiable when taught orally or in writing;

(2) If scientific law is taught, written textbooks statements identified as scientific law shall have no known exceptions of verified empirical data;

(3) If scientific theory is taught, the theory shall be identified as theory when taught orally or in writing. Empirical data and conjecture may be presented to support taught theory where considered instructive. As used in this subsection, the term “theory” shall mean theory or hypothesis;

(a) If a scientific theory concerning origin or destiny is taught without the teaching of opposing scientific theory, the taught theory may be criticized by the teaching of conflicting empirical data where considered instructive;

(b) If scientific theory concerning biological origin is taught in a course of study, biological evolution and biological intelligent design shall be taught. Other scientific theory or theories of origin may be taught. If biological intelligent design is taught, any proposed identity of the intelligence responsible for earth’s biology shall be verifiable by present-day observation or experimentation and teachers shall not question, survey, or otherwise influence student belief in a nonverifiable identity within a science course;

(c) If scientific theory concerning biological origin is taught in a textbook, the textbook shall give equal treatment to biological evolution and biological intelligent design. Other scientific theory or theories of origin may be taught;

(4) If an event previous to written history is taught, the event shall be supported by physical evidence. Physical evidence and data concerning the event may be taught where considered instructive. Conjecture concerning an event previous to written history as to the occurrence of the event, cause of the event, date of the event, length of time for the event to occur, subsequent effects of the event, or other speculative details shall be taught as theory or hypothesis as specified in subdivision (3) of this subsection;

(5) If a naturalistic process previous to written history is taught, the naturalistic process shall be duplicated by an analogous naturalistic process. Details of the analogous naturalistic process may be taught where considered instructive. Conjecture concerning a naturalistic process previous to written history as to the occurrence of the process, cause of the process, date of the process, length of time for the process to occur, process conditions, process mechanisms, process materials, or other speculative details shall be taught as theory or hypothesis as specified in subdivision (3) of this subsection;

(6) If a scientific theory or hypothesis proven to be false is taught for historical, illustrative, or other reasons, the theory or hypothesis shall be identified as false when taught orally or in writing.

So half of the pages of the textbooks must be dedicated to intelligent design, and all the pages must contain only material backed up by evidence. But intelligent design lacks evidence. If this were entered into a computer on Star Trek, it would blow up.

Pay special attention to this very interesting clause.

If biological intelligent design is taught, any proposed identity of the intelligence responsible for earth’s biology shall be verifiable by present-day observation or experimentation and teachers shall not question, survey, or otherwise influence student belief in a nonverifiable identity within a science course;

Think that through. So if you’re going to teach intelligent design, you’re either going to have to be totally silent about the identity of the designer, or you’re going to have to back up that identification with evidence. So either you’re going to teach this stuff as supported by evidence while avoiding any suggestions about how it was done by this designer, or you’re going to have teachers turning the science classroom into a Bible studies class while they trot out tired theological arguments about the nature of God.

But catch that cunning last bit: you’re also not allowed to use evidence to question the students’ faith in a nonverifiable being — an entity without evidence or contradicted by the evidence.

There isn’t going to be a single textbook on the market anywhere that meets these criteria. But they have an out: they’re going to put together a committee that will provide supplemental material on creationism of equal weight to the textbooks. And that’s where the state of Missouri will throw a big chunk of their education budget…into authoring and publishing a creationist textbook that will be given to all of their schoolkids, written by a select team of “nine individuals who are knowledgeable of science and intelligent design and reside in Missouri.”

There is another problem there. All of the people who are knowledgeable about both, who actually understand how science works, will also know that intelligent design creationism is bunk.

I notice the bill was introduced in August, and the last action was to refer it to the elementary and secondary ed committee; there are no hearings scheduled, and it’s not on the House calendar. I suspect that means it’s going to die the slow silent death of neglect. That’s good, but how about if you Missourians take the next step and make sure the author of the bill, Rick Brattin, and his partner in crime, Andrew Koenig, don’t get elected anymore?

Do creationists evolve to be that stupid?

It’s a serious question! I once thought that maybe Douglas Axe was going to be a serious creationist foe for a change: he has a real Ph.D. in chemical engineering, and he seemed to avoid saying the egregiously stupid things all the other creationists say. And then I saw this little clip of Doug Axe digging in his heels and denying reality — he makes a bogus mathematical argument that evolution is impossible, and flatly denies the existence of any transitional forms — and I got to wondering. Was he always this stupid and I didn’t know it because he kept his mouth mostly shut, or did he gradually become increasingly idiotic as he hung out with IDiots?

He doesn’t believe in change, which would suggest that he’s always been this way. On the other hand, he does believe in Intelligent Design creationism, so maybe he was guided towards stupidity. But then, if he believes purposeful design can shape organisms, why is he denying the existence of transitional forms?

Ah, screw it. I’m just writing him off…another creationist reveals the root ignorance of their position.
