In a response to publication of the
Cheng, et al paper in PNAS which demonstrated an evolutionary pathway to the antifreeze gene that protects fish from freezing in Antarctic water (see also
my post on it), Casey Luskin, attack gerbil of the Disco 'Tute,
invokes Stephen Jay Gould's infamous "just so" phrase. Luskin then kindly outlines the three steps in constructing a "just so" story to account for biological phenomena. Here I'll walk through Casey's steps for a parallel case to show just how specious his claim is. The parallel case is accounting for how a particular boulder, indicated below by the red arrow, got to where it was in a landslide (image used by permission of
Air-and-Space Museum).

Luskin's main complaint about the Cheng,
et al. paper is that it invokes various processes (
known to occur in nature) to account for the end product:
[It claims that] AFPIII evolved from a duplicate copy of another gene in the fish, SAS-B. They summarize their evolutionary story: "AFPIII 5'FR, intron1 (I1), exon2 (E2; icebinding mature AFPIII), and 3'FR were derived from the 5'FR, I5, E6 (SAS C-terminal domain), and 3'FR, respectively, of the ancestral LdSAS-B," and then "[a]ccelerated adaptive changes subsequently occurred in the nascent AFPIII gene."
The Gene Evolution Game
Sounds simple and compelling, right? Don't be too impressed. If you go back and read my article, "How to Play the Gene Evolution Game," you'll find that by using a combination of three magic wands -- Gene Duplication, Natural Selection, and Rearrangement -- it's a simple matter to concoct a just-so story to "explain" the origin just about any gene sequence -- no details required:
Let me walk through the steps of Luskin's Game, translating to show how they would operate in the boulder/landslide scenario.
Gene Evolution Game Rule 1: Whenever you find sequence homology between two genes, just invoke a duplication event of some hypothetical, ancient ancestral gene, and you can explain how two different genes came to share their similarities.
For the boulder that translates to something like
Boulder Game Rule 1: Whenever you find shape and mineral composition homology between a rock at the bottom of a slope and a ledge up the slope, just invoke a hypothetical breakage event and a hypothetical landslide event and you can explain how the rock and the ledge come to share their similarities in shape and composition.
So if we search the cliff above the landslide and find a ledge that has a similar mineral composition and find a portion of the ledge with a physical shape at its edge that's roughly complementary to the shape of a side of the boulder, we just invoke hypothetical breakage and landslide events to account for the boulder's existence and position, using the magic wand of gravity as a natural law in our explanation.
Second, Luskin tells us
Gene Evolution Game Rule 2: When you need to explain how a gene acquired some new function, or evolved differences from another gene, just invoke the magic wand of natural selection.
In our boulder example, that translates to
Boulder Game Rule 2: When you need to explain how a boulder acquired some nicks and chips or shape differences from the ledge above just invoke the magic wand of collisions with other boulders during the hypothetical landslide. To account for the driving force that got it to its position at the bottom of the slope just invoke the magic wand of gravity.
Finally, Luskin's third rule is
Gene Evolution Game Rule 3: When a gene seems to be composed of the parts of several genes, just invoke duplications and rearrangements of all the DNA sequences you need, so you can get them all together in the right place.
That translates to
Boulder Game Rule 3: When a boulder has surface marks of a different composition than the original ledge, just invoke collisions with boulders of a different composition during the hypothetical landslide to account for the marks, and maybe even find the other boulders that contributed the marks. Of course you'll also have to invoke hypothetical friction and hypothetical collisions, along with the magic wand of gravity again.
Luskin goes on to critique the paper for not reaching the IDist's favorite and most distant goalpost:
While previous studies had identified some of the supposedly "positively selected" amino acids as important to the antifreeze function, the authors make no attempt to provide a step-by-step explanation of how SAS-B' changed into AFPIII.
As is obvious, in Luskin's twisted world we can't satisfactorily account for the boulder's structure, appearance, and position merely by invoking known physical laws (gravity) and processes (rock breakage and collisions and friction). We have to give a centimeter-by-centimeter, bounce-by-bounce, collision-by-collision description of the descent of that particular boulder before Luskin will believe that the boulder's source is the ledge above and that its final position and appearance are due to the vicissitudes of boulders tumbling downhill in landslides powered by gravity. That's the goalpost Michael Behe and all IDists move to whenever they're confronted with an account like that in the Cheng,
et al. paper or, for that matter, in our landslide example. For Luskin, the "magic wands" of gravity and the presence of other components of the landslide together with random bounces during a landslide that are no longer accessible to direct inspection cannot explain the position and appearance of the boulder in the image: It's perfectly obvious that we have to invoke
Intelligent Falling."Things fall not because they are acted upon by some gravitational force, but because a higher intelligence, 'God' if you will, is pushing them down," said Gabriel Burdett, who holds degrees in education, applied Scripture, and physics from Oral Roberts University.

Well, a "just so" story is a lot better than the Luskin alternative, a "just not so" story.
OK Casey, how do you explain sequence homology between genes? Coincidence? Intelligent design? That doesn't even make any sense of course.
This argument amounts to "were you there"? If we don't actually see the gene duplication happen, then it is assumed that it could not happen. No matter how much evidence there is that it actually did happen. And of course if we ever did actually observe it happen, then it happened in the lab and not in nature, so that doesn't count!
Unless we actually see the rock fall, it couldn't fall. And if we actually do see the rock w=fall, we must have done something to make it fall, so that doesn't count! Heads I win, tails I hit you on the head with the rock.
Naon Tiotami · 27 January 2011
I'm sure Casey would retort with: "We have a lot more evidence for the existence of falling rocks than evolving genes, so there, you're all really mean to me."

Has anyone asked Casey Luskin to describe how the antifreeze gene was designed? From what? By what process? At what time, and why?
Casey demands a centimeter-by-centimeter description, but refuses to describe his alternative even at a parsec scale.

Dave C -- what RBH and Tiel said, plus the first gene duplication often makes a second duplication more likely, and a second duplication makes additional duplications even more likely, so you get a "snowball" effect.

For Dave C here's a back-of-the-eyeball calculation to illustrate what Tiel and I meant. (Somebody check my math: I'm subject to "chemotherapy brain" and am doing it in my head.)
Say there are 10,000,000 eelpouts (Cheng's icefish) in the Antarctic population, each with 25,000 genes (not unrealistic numbers). That's 250,000,000,000 genes in the population at any given time. At a gene duplication rate of 0.01 per gene per 1,000,000 years, we expect to see 2,500 gene duplications in the population every year, or one duplication in every 4,000 fish per year. In 10 years, assuming no biases regarding which genes duplicate, it's possible that every gene of the 25,000 in the eelpout genome will have duplicated at least once in at least one fish. In 1,000 years it's practically certain that every gene will have been duplicated at least once in at least one fish. Thereafter it's up to natural selection and genetic drift, both of which are known to operate, kind of like the magic wand of gravity. :)

Mr Luskin has given a perfect example of the arguments presented by most creation "science". It is not about carefully checking facts and conclusions it is about presenting an argument that will convince the villagers (in other words a good story).

In fact we do observe genetic changes, genetic variations within species and genetic divergences between populations etc, etc..... An we even see duplication variations within species.....
So Casey Luskin says we don't have enough proofs that the antifreeze gene evolved from a common ancestry from another that is homologous? Casey Luskin will say that in fact scientists didn't prove anything and that we know nothing and Casey Luskin will probably argues that the hypothesis of
Goda mysterious designer for the antifreeze gene is a equally plausible explanation.We just have to forget that genetic changes occurs all the time even genes duplications..... And we have to accept a alternative we never did observe with no mechanisms at all!
You can equally say to a geologist that nothing proves that fold mountains are the products of Plate tectonics despite the fact that Plate tectonics exists and moves, that we have marine fossils in the mountains. And after that you can says that the hypothesis of
Goda mysterious designer for fold mountains is a equally plausible explanation!Casey Luskin is Definitively a ass clown!

I had my own just-so story this past Sunday. I had left my apartment for three hours, and came back, and found half of my kitchen was flooded--the half not adjacent to the sink!--and there was some ugly black stuff in a ring in my sink, and some puddles on the counters to the left.
Casey-Luskin-style thinking flashed through my head--oh no, some evil twit is pulling some nasty prank on me--but my decades of scientific training prevailed. I hypothesized that perhaps it was perhaps bigger than previous refrigerator leaks--but papers on the floor (no, not left there for scientific purposes) bore no signs of recent flooding. Wait, I could hear some dripping, to the left. The sound was maddeningly hard to localize, but it was near the slightly flooded counters there, and there was a swirl of the same black stuff. OK, hypothesis: the flood waters rose from the depths of my sink somehow and went left. Only left? It seemed that way, so I stared at the sink very carefully, and lo, there was apparently a tiny tilt favoring the left. OK, time for an experiment, and I filled the sink, just enough until it could spill. And indeed, it spilled left, and I turned off the faucet. At which point, I waited for the water to drain, and nothing happened. So I turned on the garbage disposal until the water was halfway gone, turned it off, and after a few seconds, the drain belched! With ugly black stuff filling up half the sink again. Oooh, good one.
Well, anyway, I continued with my experiments, had a pretty good just-so story, fiddled more with the garbage disposal, reset it, made sure everything was pureed, got out all my never thrown away torn up old shirts and put them in the flood, then went downstairs to get one of our building experts. I had a theory, and he agreed with me: a frozen pipe, something I deal with since I live on the floor just above the parking garage. In particular, he confirmed the same mess is a known issue on my floor.
So in this weather, I'm running hot water through my kitchen sink more often and carefully not leaving gunk in the disposal. I can't even begin to think how the Casey Luskins of the world deal with anything beyond animal instinct reflexes.
DS · 28 January 2011
William makes a very good point. We all use the scientific method and scientific thinking every day to solve lots of problems in everyday life. It's really nothing more than common sense, parsimony and methodological naturalism in action. In the past, it was easy for people to jump to all sorts of supernatural explanations for everything. That didn't work out so well. Of course you can still stick with that, but why would you when the alternative has proven to be so successful and productive?
I sometimes wonder what actually goes on in the minds of people with the supernatural approach to reality. Do they really consider ghosts and goblins first, or do they realize on some level that that explanation has never really worked in the past?

I can just see Casey Luskin in a paternity suit, telling a judge that the DNA test is merely a just-so story. "Breathtaking inanity" indeed.
I've found comparing evolutionary science to DNA paternity tests a pretty effective eye-opener for laymen who don't have a good grasp of evolution, and for the scientifically literate who had no idea just how bad an evolutionary understanding most people have. Usually the bulk of the conversation is spent trying to explain to the misinformed that the paternity test is an example, not an analogy. It's a remarkably difficult notion for them to wrap their brains around.

Casey Vs the Crapper, A parable.
(Basic premise not mine, I don't know who from, improved and expanded by me:)
Casey exits his home in the morning to find crap all over his house. A man on the sidewalk was observed to fling one piece of crap at the house before he stopped when Casey exited. Casey, being observant, notices all the crap on his house and crap drips leaving a pie shaped pattern on the ground converging on the man on the sidewalk. This man is also observed to have an empty bucket of crap and a half empty bucket of crap. The crap missing looks to be about the same amount on his house. The man has crap all over his hands.
"Crap", Casey says, "Because I never saw ever bit of crap that was flung at my house, I have no idea who did it. So it could only have been puffed here by an intelligent agent! I must have sinned!"
Seriously though, if I am not mistaken that is the consequence of this kind of thinking.

Leszek,
“NS would be falsified if unfit survived. If, in nature, those with birth defects and so on lived about as well as the otherwise healthy, NS would be disproven.”
This is where we learn that NS is just a tautology. The strong survive. What does strong mean? It means those who reproduce effectively. What does survive mean? It means reproduces. Thus:
Those who reproduce effectively reproduce.
similarly, the weak perish, or
those who cannot reproduce, do not reproduce. It’s a tautology and tell us nothing.
You can’t disprove a tautology.
when you say
those with birth defects and so on lived about as well as the otherwise healthy, NS would be disproven.”
birth defects = does not reproduce live about as well = reproduces
you cannot conclude
1. those who reproduce effectively reproduce 2. therefore, reptile change into a mammal due to undirected causes.
RBH · 28 January 2011
Carolyn James · 28 January 2011
RBH,
"Fitness’ to Darwin meant not those that survive, but those that could be expected to survive because of their adaptations"
It's still a tautology. How can
"those that survive, but those that could be expected to survive because of their adaptations"
not mean
reproduce efficiently?
What you're saying is just
those who are expected to reproduce, will reproduce
If something is "adapted" then of course it will reproduce. NS tells us nothing
I'm still waiting for you to come up with a means for falsifying NS.
Carolyn James · 28 January 2011
"Darwinian theory rules out quite a lot. It rules out the existence of inefficient organisms when more efficient organisms are about."
http://www.talkorigins.org/faqs/evolphil/tautology.html
How do you define inefficient? If you could rate all two million species according to their fitness, what species should not be there? How do you draw the line between efficient and inefficient. I'm sure all the bottom 100 thousand species could be described as inefficient by they're still here.

"It rules out change that is theoretically impossible (according to the laws of genetics, ontogeny, and molecular biology) to achieve in gradual and adaptive steps (see Dawkins"

Those species that cannot possibly exist, do not exist.
here, theoretically impossible = cannot possibly exist

You misread it: It means we can independently identify variables that would, if present, contribute to relative reproductive success, and then we can test whether that predicted relative reproductive success indeed occurs. Read all of the linked explanation.
You're just using synonyms and adding in more words.
Now you're saying:
Those who have variables which contribute to reproductive success, will successfully reproduce.
All you have done is changed "reproduce" to "contribute to reproductive success"
It's still a tautology
When you test whether or not someone with "variables of that contributes to reproductive success" actually reproduces, then of course they will reproduce.

By the way, Raven, If you do what Darwin did which is point to a simple eye, then an eye more complex, and another eye even more complex, that's not proof that NS acting on RM caused the change of those eyes. That's just assuming that NS is the cause.

This person does know that "tautology" means true regardless of evidence or lack of it, right?
If NS were a tautology, that would make it true, period, and as that is not generally what anti-evolutionists want people to think (as I understand it, anyway), I really don't get this choice of tactic for their propaganda efforts.
Though whether it's a tautology or not, the statement
"genetic varieties that give their carrier a higher reproductive success than other varieties in the same environment, will tend to spread in the population in that same environment"
is pretty much common sense for people to bother to think about it.
One thing that keeps it from being a tautology though is that environment is not a constant. Indeed, if one species evolves in an area, that by itself changes the environment for other species with which it interacts, sometimes producing a positive feedback effect, analogous to an arms race. (Oh, and the so-called Cambrian explosion appears to be a major example of this).

As for the APoA-1 mutant gene that confers protection from cardiovascular disease, Raven, I haven't heard of this gene, but it looks like it does this by "preventing the synthesis of apoA-I protein, which results in an absence of plasma high-density lipoprotein." In other words, this is yet again a case of a mutation destroying a function which just happens to have a benefit. This is not evidence of NS being creative. For NS to be true you have to show that it can create new molecular machine, not that it destroys machines already built. Moreover, single mutations are not evidence. Many proteins have very few sequences in common.

I have said it before, but I will repeat it because the above conversacion proves my case: What is needed to see who is making a sensible argument is reading comprehension. Even without having to understand the details, the math or the science one can see that Ms. J has found and excuse for not answering any questions and has shown many if not most of the tell tale signs for identifying trolls. I know it hurts, but I don't see a way a way out without stoppind the feeding and having the troll claim victory.......just keep in mind that the claim to victory has as much credibility as the rest of the troll's statements.
Chris Lawson · 29 January 2011
Not feeding the troll, but I found it amusing when said troll thought that finding regular sequences in astronomical signals would be proof of intelligence. The troll is clearly unaware of Jocelyn Bell and Tony Hewish's 1967 discovery of an incredibly regular radio signal from light-years away. Their first thoughts, naturally, were that these were the work of alien intelligences and they even called the signal LGM for "little green men." They investigated further and discovered that the signal was from a rapidly spinning neutron star. We now call these stars pulsars and Hewish won the Nobel for it (Bell was controversially omitted).
And it doesn't end there: many spiral galaxies are distributed along a Fibonacci sequence. Even prime numbers follow amazing patterns (Google Ulam's Rose).
If Bell and Hewish had been IDists (or UFOlogists) they would have announced the discovery of alien intelligence and wrapped up their research then and there.

This example of beneficial mutations and HIV reminds me of why:
creationists are so evil and malevolent. If satan existed, he would be their leader.
Before modern medicine, a novel disease like HIV would have just burned through the entire population. For a few generations, most people would spend years being sick and die young. Eventually, the resistant segment would take over the population and we would forget all about it.
We don't have to do it this way anymore because of science, the subject they attack whenever they can on cult religious grounds.

Raven says: "The advantages of not dying should be obvious even to creationist trolls"
To a fundy, HIV is god's punishment for gay sinners. They are supposed to die. If everything is designed by god, then this mutation must also be made by god and it must mean that god doesn't want some gays to die.
Talk about cognitive dissonance!

I am a little ate to the party, put WRT this character Carolyn, what is the difference between natural and artificial selection? There’s got to be something for selection to work on, regardless of whether natural or supernatural causes for the variation? Isn’t the cause of genetic variation irrelevant; won’t natural selection decide the outcome anyway?
Differential reproductive success is what it is. Or is Carolyn trying to sell genetic nihilism?
DS · 30 January 2011
Carolyn proves once a gain, that if you ignore all of the evidence, make crap up without any evidence, then demand evidence from everyone else, that you can do the creationist fertility dance. Just put your hands over your eyes, close your mind completely, click your heels together three times and repeat "we're not in Kansas anymore". Everyone else will be completely fooled and you will win every time. Especially if you don't take your hands away from your eyes.
Now who else do we know who uses this same routine? EIther they are all the same poster, or they at least all study under the same Jedi master. A little green guy with pointed ears I think. May the farce be with you.

@william e emba
Thanks for the extra information on he history of pulsar research. I like hearing stories about scientists who were spurned only to be vindicated later. The problem with the ID crowd is they portray themselves as the spurned geniuses but do not understand that (i) it takes *evidence* to switch from spurned to vindicated, and (ii) even the worst examples of modern scientific oversight were rectified within a generation...meanwhile creationism has been losing its battles since 1859.

Casey's argument reminds me of the Dave Chapelle skit talking about if he were on the OJ, R Kelly, etc. juries.
With two important differences. One: Chapelle's demand for for ridiculous levels of proof was intended to be funny. Two: it achieved its purpose (well, IMO).

Couple of unrelated comments: On common descent falsification, there is a "shadow biosphere" theory, unsupported by evidence at this time, of organisms of either alien origin, or from origins of live other than the one which produced life as we know it. An organism with a completely different genetic code would support this theory.
In 1959, in a required MS level geology course, I received a half semester tirade against continental drift. I used to have a 25 page purple mimeograph handout about it.
Basic problem was that continents were pictured as ships sailing in a sea of denser rock, but no evidence of bow waves or wakes. Also no proposed force or propulsive mechanism. Plate tectonics is a rather different concept of how continents would be moved around, and was widely accepted with a few years time after my experience.

Reductionism and creationism go hand in hand. The real world is far more marvelous than creationists can imagine. Pity on them.

I have a few questions. I wasn't able to read the actual article in Nature since I don't have a subscription and I have only read the summaries of others. I trust that someone here has actually read the article.
The article states that a gene database was searched for matching subseqences. Were non-coding regions searched as well?
How long is the code for the digestive emzyeme that has matching subsequences.
How long is the code for the antifreeze protien?
How log were the matching end points?
Do these matching end points match the end points of other genes?
Intelligent Designer · 3 February 2011
I would also like to know if the number of chomosomes that the two compared species have match and if the two compared genes were on the same chromosome.

It would also be interesting to know how they compare nucleotides. Do they actually compare the nucleotides for a match or do they compare taking into account equivalent codons.
The probability of exactly matching a 9 letter nucleotide sequence is 1 in 262144. The chances of a match taking into account equivelent codons is 1 in 8000.
I think asking questions about how comparisons are made affects the plausability of the conclusions that were drawn from the data.

Luskin's argument is too crude to merit the name of sophistry. By calling natural selection a "magic wand," he is assuming the very point he is trying to prove--that evolution by natural selection is a false or incomplete explanation of speciation.
In other words, stripped of pseudo academic flourishes, his entire argument is founded upon question begging. We can ignore the fiddly-bits, leaving more time to marvel at the dishonesty of the IDeist mind.

The duplication and billion years thing - there might be duplications all the time, but there is no positive selection for them and they are lost (reaching only a rare population frequency that we don't spot), like a red headed orphan raised in Tibet. How many generations would that red headed trait last in the population?
Also, many of those (partial)duplications are harmful - Down's syndrome, many cancers. Posters at ASHG are loaded with photos of kids and embryos with chromosomal mutations that leave them deformed or dead. It's extremely common, but these traits are negatively selected.
So it's not a billion years to get a beneficial mutation, it's only every billion years that an environmental condition AND a duplication of ONE gene act to favorably select that gene. But when the conditions change and new traits are needed, natural selection promotes them from the ranks.
Or to put it more familiar terms - by the end of ww2, you could become a Luftwaffe pilot in a couple weeks because the death rate was so high. Sometimes there's nothing like tremendous mayhem to send positive selection into overdrive.

And unfortunately with the boulder analogy, God never gives us proof of his divine guidance, like having those boulders spontaneously assemble into a nice bungalow at the base of the cliff.
Nope, Irreducible Complexity only gets invoked as a convenient attack on scientific theories. Where is it other times? Where are the spontaneously formed houses? How could God be so careless as to not do that for us? Where are the clouds in the perfect shapes of Euclidean solids? Why aren't any of the Great Lakes in the perfectly detailed outline of a pony? Why don't butterfly wings have Bible verses on them?
BurfordHolly · 26 February 2011
Back to that scenario about children with chromsomal duplications or deletions - these traits can be recessive, so when you see one of these cases and they show the pedigree of some family from an isolated population like a village in Malta, you see that the child is the result of the kids gandparents being cousins and the father married his own aunt. Natural selection in a large population only reveals these duplications rarely, but just a little selection (such as inbreeding) in an isolated population shows that the actual rate of gene rearrangements is much much higher than you would suspect, and thus cousins should not marry. And when conditions change, there are lots of mutations available to be selected, and probably a population bottleneck that will swiftly increase the allelic frequency of the mutation.
If mutations were as rare as the ID people imply, there would no harm in siblings marrying each other generation after generation, and even illiterate nomads know more science than that.
