Pinkoski again: How stupid can creationism get?

I've been having some fun with a bizarrely didactic creationist comic book by one Jim Pinkoski that purports to explain all the flaws in evolutionary biology. What it really is is the most astounding collection of bad creationist arguments I've ever seen gathered in one place. I've been trying to slog through rebuttals, but unfortunately, it's like every word and phrase is so far off kilter that it's going to take me forever to get through it. One putative "problem" that I've already dealt with is that we only use 10% of our brains, and so scientists are stupid and untrustworthy, but here's another one: evolution requires that everything be extraordinarily brilliant. Or in comic book speak,

Evolutionists are saying that "teeny-tiny" life forms somehow willed themselves to "evolve," which means that we must credit
MICROBES
with being smarter than Albert Einstein!!!

How many errors can we find in that one sentence? Well, evolutionists have never said anything of the sort, evolution isn't a matter of willing new features into existence, and no one credits bacteria with high intelligence. Pinkoski illustrates this bogus concept with a "steg-o-moeba" trying to will itself into becoming a stegosaurus.

Pinkoski's errors
Pinkoski's errors

Here's a closeup of that little amoeba wishing it were bigger and had eyes. Cute. But totally divorced from reality.

This is entirely contrary to what evolutionary biology actually teaches: there is no intelligence behind changes. There are variations within populations, and the variants that are most successful at coping with local, short-term conditions are represented at a higher frequency in subsequent generations. Pinkoski's ideas are actually anti-evolutionary, and even have a technical term associated with them: orthogenesis. If there were actually a program of evolution driven by the will of organisms, that would be evidence against evolution. You can't refute modern biology by inventing a thoroughly silly argument, and pointing out how silly it is—because evolutionary biologists will also tell you how silly it is. It is a classic straw man.

It gets better. Take one straw man, and compound it with a gross misunderstanding of how animals develop, and turn it into a mega-straw man, a Tyrannosaurus rex of straw.

If "evolution" is true, then each major life form would have to evolve it's own eyes (as well as every other major organ of its body)!

Again, if evolution is true, it predicts exactly the opposite: new species do not evolve the majority of their features anew, but inherit them from the parent species. Homo sapiens did not have to generate four limbs, a head, a pancreas, a spine, etc. de novo—we got those from our predecessors. The process is called descent with modification, not descent with reinventing everything all over again every time.

Orthogenesis, weird ideas about evolution without inheritance…Pinkoski is about to ratchet the absurdity up a few notches with his very own novel thoughts about bilateral symmetry.

Common sense tells us that "evolving" all the individual parts of the eye is impossible, but I want to address an aspect that most overlook—
Pinkoski's errors
If the "eye" really evolved, when did all these animals decide that 2 eyes were better than only 1 eye??
"Evolution" depends largely on mutation—and it only makes sense that if an "eye" suddenly mutated into existence, then that animal would only grow 1 of them!!
SO WHERE ARE ALL THE 1-EYED T-REXES, 1-EYED ALLOSAURS, 1-EYED STEGOSAURS, 1-EYED VELOCIRAPTORS, ETC.?? WHERE?!!

Ouch. That's so stupid it hurts to read it. Apparently, Pinkoski has this vision of evolution in which each new species arises from an amoeba, which has to sprout each of its organs by force of will, and each step lingers about long enough to limp about and leave fossils of its pathetic intermediate state. It's not just eyes, it is the whole shebang.

Believe it or not, "bilaterally symmetrical" prove how impossible evolution is! Just like it was stated on the previous page about the evolution of the eye, the same thing applies to arms, to hands, to feet, to ears, to fins and to wings, etc.!

EVOLUTION SAYS THAT EACH OF THESE ORGANS EVOLVED BY MUTATION, AND IF THIS WAS TRUE THE MUTATION WOULD HAVE BROUGHT FORTH ONE OF THESE BODY PART AT A TIME! SO, WHERE ARE THE 1-FINNED TURTLES, 1-WINGED BIRDS, 1-FLIPPERED PORPOISES, AND THE 1-ARMED 1-EARED 1-LEGGED "APE MEN"??

Evolution is refuted because there are no fossils of one-winged pigeons lacking a pancreas and a beak? If there were collections of the kinds of organisms Pinkoski describes, we'd have to reject evolution, because clearly there would be some extremely peculiar piecemeal assembly of animals going on—the kinds of transformations that would violate modern biology's conception of organisms as integrated wholes.

Just as I've inherited four limbs and a head from the great and ancient tetrapod class, so too is bilateral symmetry an inheritance from ancestors even farther back. Bilateral symmetry is over half a billion years old. What it reflects is the presence of signalling molecules that define dorsal and ventral (back and front), molecules that define identical domains on the left and right sides. Your left and right eye are not independent creations, but are instead the product of the same genes expressing themselves in response to simpler signals that are active on both the left and right sides of your head during embryonic development. It actually requires specific, additional mechanisms to break symmetry, and vertebrates that are normally lopsided, like flounder, are generated by a secondary modification of initially symmetrical forms.

Pinkoski's argument rests on a total absence of awareness about what biological evolution really says. Creationism is an intrinsically ignorant enterprise that crumbled away long ago for people who actually study the evidence, and only persists in those who refuse to examine the science behind it, and think that stacking misconceptions on top of one another is a path to the truth. This particular creationist story got nothing right.

  • Evolution does not occur because individuals want it to happen. Mutations arise by chance, and populations evolve by the survival of favorable (and sometimes not so favorable) variants.
  • Every new species is not an independent creation. It inherits a full suite of characters from its parent population, and modifies their expression.
  • Intermediate forms are not incomplete or non-functional or lacking in major characters. Every species is complete and successful in itself, but is different. Evolution is about acquiring differences, not a drive towards some superior, more complex form.
  • Bilateral symmetry is not a problem for evolution. Mutations that generate a feature on one side of an animal tend to be in response to molecular signals that are present on both sides of the organism; paired features are often easier to evolve than asymmetries in animals that are inherently bilateral.

The disturbing thing is that this pack of lies is part of a series of which a quarter million copies have been distributed by Amazing Facts, a "media ministry" (I guess that's what they call it nowadays to avoid the taint of the word "televangelism") based in Roseville, California, and led by a genuine, literal troglodyte, Doug Batchelor. It's 56 pages long, and every sentence is either cockamamie nonsense or outright lies. As a science educator, I have to look at this thing and think…boy, do I have a lot of work to do.

It is funny how all of his arguments are so turned upside down that they are better arguments against Special Creation than against evolution. Is this their new strategy? Turning everything around? Stating boldly that arguments for evolution are arguments against it and vice versa?

Boggles one's mind...

Two probably ignorant questions about bilateral symmetry:

1. Is it considered an asymmetry that human organs are not that symmetric, e.g. the liver is on one side of the body? How about the heart's structure, or the brain's left and right sides?

2. Does bilateral symmetry have an obvious inherent advantage over, say, quadrilateral symmetry or radial symmetry, or is it more or less an accident, like the handedness of amino acids?



's avatar #28193: PZ Myers — 06/12  at  03:11 PM
1. Those are asymmetries, and there's a lot of very cool work being done on how those asymmetries arise.

2. I'd guess the advantage is in motile organisms: specializing for movement in one direction is "easier". It could also be an accident, in that all it took was a single symmetry breaking event (the formation of the D/V axis) to produce a bilaterally symmetric organism. Those two alternatives are not contradictory.

1. Well, I'm sure this work is very cool. It's too bad I can't understand any of it unless someone like you digests it for the layman - I can't even read papers in my own field and understand them.

2. I see... it's fascinating, but see point #1.

By the way, completely off-topic: when did you read your first unassigned scholarly paper in your field? I did a week ago and I'm going to start my final year of college this August, but I'm fairly certain everyone else around here started a lot earlier than that.



#28197: — 06/12  at  03:40 PM
The symmetry issue is a question of breakage in response to the environment.

A simple single cell floating around can be approximately spherically symmetric. As soon as something acquires some sort of mobility such as a flagellum (or even many cilia) which impose a direction or axis, you get left with radial symmetry. The same thing applies to the addition of a single direction of force but immobility - you get the radial (or spiral) symmetry of a tree. If you are big enough to experience gravity but also move, then you've usually constrained 2 axes and are left with being bilaterally symmetric.

When you are a mess of unintelligent chemicals, repeating structures in as many directions as possible is simpler than coming up with new rules for each direction. Just as repeating structures within a structure is also simpler, eg lobes in lungs and twigs on branches. Fractals illustrate this well.

But wait! Why did the dino have a left side *at all*? I mean, wouldn't it've made more sense to have just made the one half and then, if that worked out well, made the other half out of sheer force of its dino will?

Can I decide to, say, evolve a few extra fingers, and my descendants in a few thousand years will get them, too, or do a bunch of us all have to think the same thing really hard? Anyways, maybe in 150k years, we'll find that Einstein willed himself to evolve into, um, a humanosaur?

That's right up with Jack Chick in the comic book pantheon; truly painful. As old Jack would say: YAAAAAAHHHHH!!!

There were also several grammatical and punctuation errors in the short excerpts cited here... Come to think of it, I want a copy!

P.Z., thanks for spending valuable time refuting this towering rubbish for us-- what an onerous task. Pity that such nonsense exists in the 21st Century; humanity should have evolved culturally, educationally and spritually far beyond this garbage by now, especially in the (har) scientifically/technologically developed world.

Is there any chance that Pinkoski is actually on our side and trying to make the creationists look more stupid than usual?

So sue me, I'm an optimist. OK, so I'm not really, but if he's a creationist I hold out little hope for the intelligence of man.

"Say a fish evolves stripes to look like, to mimic, a really dangerous poison fish, so predators stay away. My question is, how'd he know to do that?" an otherwise bright roommate once asked me. So I've heard that kind of thing in person. Nevertheless,

I'm sure Pinkoski will either ignore it or simply label PZ an unbeliever, which in PZ's case is true...

I was lucky enough to get to take a tour of a morgue one time (at the USC School of Dentistry) and saw some really fascinating physical anomolies, including the torso of a man whose body was a mirror image of usual: his heart tilted to the right instead of the left, his liver was on the left instead of the right, etc. They discovered it when he went in for gall bladder surgery and it wasn't where it was supposed to be. The surgeon asked him to donate his body to science after he died and he agreed.

BUT ... it wasn't a hodgepodge, with organs strewn around willy-nilly. It was an exact mirror image of the "standard" organization.

As I said a while back, I spent too much money (justification by movie analogy).

I've not gotten to the dinosaur issue, but to simply peruse it, assuring it being the revised edition, it was what I saw on the Ferret site. It is.

I am looking at the Sabboth issue. What I see there is the basic Catholic bashing I saw from the 7th Day Adventists, etc. I am not impressed that he skipped right over the keys verse from Jesus himself. Let me get my bibledatabase up ....
From Matthew:
16:18 And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.
16:19 And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.

So now we see that Pinkoski is vehemently against Christ himself setting up an earthly authority.

His logic fails here, too.



#28227: Raven — 06/12  at  10:05 PM
Those are asymmetries, and there's a lot of very cool work being done on how those asymmetries arise.


A PubMed search on "asymmetry" returns 18907 hits, which is a little unwieldy--is there a particular author or topic you'd recommend starting with?

Also, are there different "degrees" of asymmetry--for example, the mouse left lung has one lobe and the right has 4-5 (depending on the source)? Is this asymmetry on bilaterally otherwise similar structures qualitatively different from the liver's asymmetry of shape/placement, or is asymmetry basically the same thing in all cases?

Thank you for a most interesting topic.



#28228: Jim Pinkoski — 06/12  at  10:24 PM
I just read over your posts, PZ -- Steve informed me that you were "tearing me a new one" so I thought I'd check it out. My dino book was, in many regards, done in "jest" -- in other words, I know that there was no steg-amoeba floating around thinking about becoming a stegosaurus! Duh! It was an illustration of a concept of the foolishness of ANY microorganism being able to grow into a multicellular larger life form -- as was the example of 1-eyed dinos -- you think that I was talking about the direct science, but I'm like a political cartoonist, and in the evolution/creation debate I deal with illustrating absurd ideas! The intent of my book is for you to read the example, then project it back to how the organism began -- or rather, how it COULD NOT have begun -- and to show the absurdity of "bio-illogical" evolution, I'll quote PZ: "Evolutionary biology teaches that there is NO INTELLIGENCE behind the changes"! Hey, "no intelligence" is right!! Here's a supposed extra-brilliant science person, and what is he doing to credit the creative brilliance of all life around him?? He says that it all got here by "NO INTELLIGENCE"!!! Ha! What a brilliant conclusion to defend evolution with! PZ mocked me for saying that microbes would need to be credited with being smarter than Albert Einstein, yet PZ wants to credit "NO INTELLIGENCE" with creating all life!?! Wow!

Later he said that "Creationism is an intrinsically ignorant enterprise" -- when Creationism incorporates the belief in an all-powerful truly INTELLIGENT God! So the idea that Creationism is "ignorant" is completely wrong, PZ, Creationism is BRILLANCE AT WORK all around us!

Ah yes, the Creationism/evolution debate continues -- and nobody here has really ripped me a new anything, all that's happened is that a supposedly really brilliant person has made the same old mistakes by thinking that "chance" created all life, because frankly a person only using 1/2 of a per cent of his brain can see that there is NO WAY "chance evolution" put us here . . .

Hello, Jim! While you're here, I've always wondered... are beaver dams intelligently designed? I mean, designed by the beavers?



#28230: Raven — 06/12  at  10:36 PM
It actually requires specific, additional mechanisms to break symmetry, and vertebrates that are normally lopsided, like flounder, are generated by a secondary modification of initially symmetrical forms.


I phrased my last question poorly--let me restate it a little more clearly (I hope).

Are there biologically-significant different kinds of secondary modification to produce different kinds of asymmetry? Or are all the secondary modifications essentially the same, even though the results look very different? We can think of the organs as undergoing different geometrical transformations to generate asymmetry: scaling, translation, rotating, skewing--but do the different operations themselves correspond to anything biologically meaningful, or is is all just "geometry", if you see what I mean?



#28231: — 06/12  at  10:36 PM
Sir Jim Pinkoski,

You are perhaps the silliest creationist ever to grace these boards please do stick around for a while longer.

oh and:
'From Matthew:
16:18 And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.
16:19 And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.'

Just a mention these verses are given a variety of explanations, the most prevelant from scholars say he meant the body of believers was the church. Not Peter and notone overiding authoritarian church.

But again, it's the bible and interpretations vary.



#28232: — 06/12  at  10:55 PM
Later he said that "Creationism is an intrinsically ignorant enterprise" -- when Creationism incorporates the belief in an all-powerful truly INTELLIGENT God!

Just out of curiosity, can you tell me why God designed humans so 25% of us sneeze when we go into bright light from a dark area? (It's called the photic sneeze reflex, if you've never heard of it.)

It makes sense as a random mutation that wasn't actively harmful and so stayed in the gene pool, but I just don't get why an intelligent designer would decide to do that. Did he put that into my genetic code as a practical joke?



's avatar #28234: Virge — 06/13  at  12:00 AM
Ummm, PZ. It looks like Jim's got you all worked out, eh? Jim, armed with only his crayons, has deftly applied a reductio ad absurdum to show that evolution doesn't happen and could never happen. Clearly Jim is a person of immense intellect, able to dismiss all that bio-illogical evolution in one paragraph of simple logic. How could we all have missed the fact that evolution is so obviously impossible? Must be the work of The Deceiver and his demons.
[/sarcasm]

The staggering combination of ignorance and arrogance displayed makes me wonder if someone faked the Jim comment. I won't wonder for long, though, since the content of his comic is consistent with the blindness employed in the comment.

How can someone who's never studied biology, and is aware of the fact that a creationism/evolution debate continues in some circles, possibly think that such a simple solution resolves the question so utterly and finally? How can he even acknowledge that there is a "debate" if he thinks it is that simple? The only answer that seems consistent with his view is that everybody involved in the debate apart from him is completely stupid:
- the darwinists are stupid for supporting a theory that can't be right
- the creationists are stupid because they should have used JESUS (Jim's Eminently Sensible Unrefutable Syllogism) all along.

*sigh* At least debates with IDers sometimes get down to considering the evidence, even if they won't ever state their theory and conduct science of their own.


Jim, if you every come back to comment again, perhaps you could explain why creationists don't rely solely on your ultra-simple argument.



#28238: pough — 06/13  at  01:20 AM
Virge, it's obvious if you read his post. You have to be using 0.5 percent of your brain to understand the ultra-simple argument!



#28239: — 06/13  at  01:59 AM
Mnemosyne, some of us actually enjoy sneezing. Recall that people used to snort snuff, although they probably did it more for the tobacco rush than the sneeze. I wonder why the practice disappeared; did people become so fastidious that being sprinkled with snot and tobacco dust ceased to be acceptable?

Pinkoski is content to think that assuming his conclusion is the height of logic, and that only a fool could disagree. I don't think there's any way to reach someone like that.

It hasn't been much discussed here, in the months that I've been reading, but teleological beliefs are pretty common. People used to ask me "Why are there ants?" or "What's the purpose of flies?" The ones asking weren't creationists, but they weren't entirely familiar with evolution, either (or, for that matter, small businesses in niche markets).



#28240: — 06/13  at  02:01 AM
For people looking at symmetry breaking in vertebrates where the orientation of your internal organs is established on top of the logic of your body being symmetrical, you can check out a review here:

Genes Dev. 2003 Jan 1;17(1):1-6.

It turns out, if you mess up the switch, you can actually reverse the orientation of your internal organs, and essentially be just fine. It might be too technical, but some of the basic idea is that you can build of a gradient of a diffusible signal by diffusing a signal into a region where the net flow of solution is in one direction. It is more complicated than that, but you can go from being symmetrical to asymmetrical. Another well known system for symmetry breaking is known as "lateral specification" whereby very small difference between two cells, almost random differences, can amplify feedback loops, leading the cells to different developmental fates. The interesting thing here, is that in many cases, either of the two cells can go in a particular direction- the system is so sensitive it is like trying to balance a teeter-totter or see-saw, you will eventually go one way or the other.
