Lifecode: From egg to embryo by self-organization

Category: BooksWeirdness
Posted on: July 17, 2007 8:55 PM, by PZ Myers

As I mentioned before in my review of Stuart Pivar's LifeCode: The Theory of Biological Self Organization, I'm actually sympathetic to the ideas of developmental structuralism. This is the concept that physical, mechanical, and chemical properties make a significant and underappreciated contribution to the acquisition of organismal form; genes are not enough, do not carry a complete specification, and what we have to consider is interactions between genes, environment, and cytoplasm. Good stuff, all of it — and I'd like to see more work done on the subject. In my review, though, I had to point out that Pivar hadn't actually addressed any biology, and that his modeling was little more than an extended flight of fancy, unanchored by any connection to any embryology.

Now Pivar has put out a new version of his book, Lifecode: From egg to embryo by self-organization. I'm sorry to say it doesn't address any of my criticisms, and is even worse. This is not a scientific theory, and it isn't even a collection of evidence: it's a jumble of doodles. I read through it all this afternoon (there really isn't that much to read), and I have to conclude it says nothing about the development or evolution of biological organisms, although it is relevant to something else.

What seems to be new in the book is a set of experiments, of sorts. Pivar's model of development has long been that we achieve the diversity of organismal form by starting with a torus, and that fluid movements and distortions of the toroid form lead to the more elaborate forms at the end of development. The donut is the unifying principle underlying everything (hmmm, makes one wonder if there is a tie-in to the new Simpsons movie). So what he's done in this work is make some flexible plastic toroidal tubes filled with fluid and flexed them and twisted them, and taken some pictures. These balloons of fluid, as you might guess, buckle and wrinkle in predictable ways — ways that, in Pivar's interpretation, leap to be represented as morphogenetic events. A tube that is bent, for instance, makes a series of wrinkles with an even distribution that look, very vaguely, like maybe you could pretend they are segments.

So he does pretend. At length.

We already know that segmentation does not form as a consequence of responses to distortions in a tube. Primitively, it is by a sequential partitioning of new segments from an undifferentiated mass; in many insects, it is set up by patterns of interaction between genes. These are genes that are fairly well-characterized and have been found indispensable to the process; as I wrote in an earlier article, general rules like the ones Pivar is modeling do not apply, and each segment seems to be hard-coded into the regulatory logic of pattern formation. It really doesn't matter how pretty a model might be—what counts is whether the mechanism being modeled actually exists in the organism. And no, Pivar's model doesn't work anywhere that I've seen yet.

Much of the book is filled with sketches in which he starts with something like his toroidal tubes, and then imaginatively transforms the tube into some animal. These transformations are completely unfettered by data or even the slightest familiarity with the embryology or evolution of the organism in question. Here, for instance, is a tube transformed into a polyp like creature and then into a spider.

pivar_chelicerate.gif

Nothing in the development of a spider comes even close to looking like that. No evolutionary intermediates looked like that. Chelicerates did not evolve directly from some kind of collapsed coelenterate, and the intermediates don't even make functional sense. The radial tentacles of coelenterates are not homologous to the legs of spiders. This is artistic self-indulgence, nothing more.

Even worse, here's a transformation that makes no sense at all. He's portraying the development/evolution of paired limbs as a process of stretching and separation of a fluid-filled tube at an attenuated midline boundary.

pivar_limb.gif

It's absurd. Limbs don't develop like that at all! The limbs in a pair develop independently, as protrusions and extensions from the body wall. Digits do not form by pulling left and right apart, like tugging on a string of sausages.

The doodles in this book bear absolutely no relationship to anything that goes on in real organisms, but after staring at them for a while, I realized what this book is actually about.

This book is a description of the development and evolution of balloon animals.

It's that bad. This is a book suitable only for use at clown colleges, and even there, I suspect the clowns would tell us that it is impractical, nonsensical, and has no utility in their craft.

A good, solid, empirical structuralism based on an analysis of the mechanics and forces on real embryos would be a useful contribution and would help us to understand development and evolution. Lifecode is not that contribution. It's not even close.

In light of the fundamental disconnect from reality represented by the substance of the book, it's almost unfair to critique the unprofessionalism of the presentation, but it's got to be said: it's also terribly done. The original Lifecode was slick and glossy, at least, even if its content was abysmal; this version is a spiral bound mess, with poorly photocopied figures. The figures have no legends, and aren't even referenced in the text; with no explanatory content at all, we're left to puzzle over them to try and figure out what he's getting at. The images of limb morphogenesis and chelicerate development above are as is — you have seen all the explanation there is, which is none. Almost two thirds of the "book" consists of photocopied papers and book chapters by other authors that are not related to the thesis at all, but are just plopped in. There doesn't seem to be any unifying principle to the selection at all, except perhaps that many mention toroids and shape. This isn't really a book at all, it's more of a scrapbook of collected fragments.

Damn PZ, you already read that whole book you are a word crunching machine. I will be the first yo admit my biology is as comprehensive as a idiot savants common sense. There is no way I would ever argue with you about evolution. I would be embarrassing. I am an evolution skeptic, but I would never debate you, because I don't know how th spell abogenesis or anthropic and neither dose my word processing capabilities.

But when Read stuff like this, I cannot discern who is right, I don't know enough to know. This is why I am an old earth ID'er. I respect your opinion just like I do a plumbers, I'm not a plumber. It is what they do. We are having a debate the same way over at the topical optogon on the origin of the universe, and if life came though evolution or not is not a concern of mine, just the cause, and as a physicist I can speak intelligently to the subject, I suggest you read it and keep up with it. Michael is only 22 years old and needs some help me thinks, find someone to help him. If you cannot understand it at least give me the same respect I give you.

Ok.Imusually don't do yjid, buy you need a dressing down

1) have I ever argued that I knew evolution wasn't true, other that questioning it
2) I might also question a plumber so he doesn't take me to the bank, but I do not question his knowledge only his materialistic honesty, by asking those questions.
3) PZ talked about the truth in a recent blog as a philosophical question, and none nof the peanut gallerynhad a clue about philosophy, It was evident, this is not your fault, but the fault of the schools and univerities.

If Lifecode was about plumbing:

The Physicist, do realize that philosophical truths have absolutely nothing to do with Biology, Evolutionary Biology, Paleontology, Geology, or any other natural science. The fact that you don't seem to care that scientists focus on explaining what the evidence shows, rather than quibble about who's responsibility it is to make things true aggravates the majority of posters here. Do also realize that Pivar has demonstrated that he knows absolutely nothing about embryological development of any sort, given his silly postulating of cnidarian to arachnid, or the fact that he thinks that vertebrate limbs start off as a muff that pinches into two, nevermind that people have known for almost two centuries that vertebrate embryos develop each limb independently of each other.

In other words, The Physicist, do realize that in Science, people are free to voice their own ideas to explain evidence, but, other people are equally free to point out when the aforementioned ideas are incapable of explaining the presented evidence, or when they run contrary to it.

Also, please learn how to spell.

I had missed that original "series of tubes" thing. So after reading that post yesterday and then encountering the "meme" yet again on a kitten picture today, I thought I'd better find out what your shared cultural reference was. Now I see that Ted Stevens' mixture of jobs/posts at the time sort of explains his peculiar mix of metaphors. However, what is it that explains Stuart Pivar's toroidal tube obsession? Blowing too many smoke rings from mind-altering substances?

Um, if it wouldn't intrude to get back to a discussion of science-- It's my impression that molecular developmental biology is really just starting to get off the ground, since genomics and the discoveries of people like Janni Nusslein-Volhard. Is this right? Because it looks like Pivar is doing the kind of flailing around that happens in science when nobody is sure how things are going to fall out. (I'd say it's like one of Kuhn's paradigm shifts, except mentioning Kuhn makes too many people mad.)
So, PZ, I'd really like to know, is Pivar just a flake? Or is he addressing questions that are up in the air, where nobody is sure of even the general nature of the answers, so off-the-wall solutions have a chance of success?

He's a flake. There are real questions, and hanging out with Gould as he claims to have done he probably picked up on them...but his approaches are unscientific and nonsensical. The two diagrams above (and the many more in the book) have no foundation in reality.

It looks as though this book is a bad attempt to re-write D'Arcy Thompson's "On Growth and Form" but without actually having studied animals or plants in any way, shape or form.
For people interested in the "mechanical" approach to body shape, Canto has a nice edition of "On Growth and Form" for less than $20. It even has an intro by SJ Gould.

The illustrations remind me of those of the early 20th century palaeontologist William Patten, who had a big thing for ontogenesis, and self-organisation as the driving force behind evolution (Gould wrote about him in one of his essays ("Shields of Theory and Actuality" I think). Patten was an interesting chap, and decided that eurypterids evolved into cephalaspids (he even thought he'd found paddle-like appendages from Tremataspis at one point). His drawings looked much like those of Pivar. And were equally invented.

It all went horrifically wrong when he tried to apply this model to human behaviour, and wrote one of the most gods-awful books I've ever read on this.

Having worked and published in one of the best labs working on the problems in limb development I second your charges of gross ignorance of how development actually proceeds. Not only do chick and mouse limbs not develop like that, but at the time of initial growth both embryos are still open ventrally meaning there is no way they can bend around and join. In fact they are as far from being joined at the tip as it is possible for them to be.

Wonder if he also things trees grow this way, never mind the blindingly obvious evidence from just looking at them that they don't, or the vast number of computer models used to generate them using fractal systems... And Physicist, they are quite correct. This is not someone developing a theoretical model of how something not well understood works, but someone inventing a new model that has no relation to what is already known to happen, through numerous observations of it. He is talking about, "Why pipes and not just channels cut in the floor leading to a big pit?", while we are talking about, "Why won't this particular glue work on this kind of pipe in cold weather?" He is babbling about basic concepts, and getting it wrong, while we are talking about the nitty gritty details and rules that determine *why* the basic concepts are what they are in the first place, and not something else.

He might as well be doing something like writing a book on some hypothetical computer based on string and rubber bands, while we are sitting in front of a real one based on silicon, and using it to experiment with how to make better silicon computers. Its not just wrong, its completely absurd.

I'd like to second that, from a layperson's personal experience. We saw early ultrasounds of my daughter in the womb. Her arms started out as buds sticking out the sides of the torso and grew outward--not a tube that separated in the middle.

This is the model theory of embryonic seld-organization
Theorem:
The forms of the animal phyla are simulated by the topological expansion of an elastic spherical surface within a spherical surface of less elasticity. Inward expansion of the inner sphere produces a torus. Circumferential expansion produces the radial body. Axial extension forms a segmented tube. Bending failure creates internal membranes which originate the appendages. The number of bends beginning with one, are the number of paired appendages. These quantified differences depend on elasticity which is controlled by the chemicals in the protoplasm, under the ultimate control of the genes The genes maintain and modify the relative size of the organs of an unchangeble bodyplan.

The shell or bones of the skeleton derive from the outer sphere, deformed by the forming body within, or, in vertebrates, without.

There are only two animal body plans. Since all life begins as a sphere within a sphere, it is proposed as plausible that this is nature's secret.

Problem is Stuart, while some of the basic stages happen as you claim, its the "basic" stages. Once division into a tube happens, other genes kick in, which then start forming bones and other things, in a way 100% different than you are describing. You are talking about a fantasy idea based on pure hypothesis, and no data. Real scientists have studied how such things form and even filmed them, and there is nothing like what you are claiming happening in any of the actual observed data. Its fine to come up with an idea when people have no clue what is going on, but when your idea contradicts what everyone else has actually observed in the lab? That's just nuts.

This reminds me of Kepler's proposition that polyhedra determined the positions of planets: a neat idea that has all sorts of cool implications, but which sadly bears no resemblance to reality. Oops.

BTW, to say that philosophy is irrelevant to science is nonsense. It's essential.

That explains it! I recall seeing a picture in Thor Hyerdahl's account of the Kon Tiki expedition, of the statues that typically showed the arms beginning to split apart at the fingertips. They appeared just as in step 10, human, in Pivar's figure above (except fleshed out, not skeletal). What further proof could one ask for?

While I don't think you should be able to be sued for posting an opinion on a blog, this review is unnecessarily scathing(which is not to say it is lacking in entertainment value), and is arguably not a review at all but merely an attack of this person's ideas.

I'd also like to add that all explanations of reality are basically metaphors that are a function of the instruments that we use to examine reality. There is a limit to what we can 'observe' and measure. We make up words and stories to explain our limited datasets. If observation with better instruments seems to contradict a good metaphor either a better(more inclusive) metaphor is formed, or someone makes up something(see 'dark matter', 'dark energy') that would allow the metaphor to still be 'right'. There is a lot of money being spent right now trying to detect something that might not exist.

I don't believe that the author of this book is ignorant of how creatures actually physically develop, he is just trying to illustrate a metaphor for development, a possibly useful idea for thinking about development. It is certainly interesting.

You'd be quite wrong. His "metaphor" doesn't fit and is strongly contradicted by actual observations of embryos. You don't need a flawed instrument to see that hands do not develop from masses that are fused at the fingertips, and we have a large body of evidence that shows that no vertebrates form limbs at that way.

In science you don't get to ignore the evidence because your fantasies are so much prettier.

"Unnecessarily scathing"? The work is so out of touch with reality and evidence and scientific explanations that I thought I was being unnecessarily kind.

Isn't the imagination a wonderful thing! Just like religion, it is an 'as if' model with no basis for reference other than the authors unintuative supposition on the topic in hand.

Doesn't reviewing a work necessitate identifying bad ideas and labeling them as such? How, then, can one say that something is not a review but is merely an attack on ideas? It doesn't make sense.

Geez, I hope I don't get sued for saying that.

There are only two animal body plans.

PZ, please make sure to have him expound upon this point at the deposition. I'd love to be a fly* on the wall as he goes into detail about that.

Hell, if your lawyer is willing to produce it, I'd probably buy a copy of the DVD.

* is that the first body plan of two?

""Unnecessarily scathing"? The work is so out of touch with reality and evidence and scientific explanations that I thought I was being unnecessarily kind."

Don't fight this fight, it's not worth it. You insulted this guy. This happens all the time on the internet and even in this thread. People don't like being insulted. You managed to insult this guy to a point that he's suing you. Suing you seems unreasonable to me, but you made it a point to insult him.

I can't imagine that he could sue you successfully, but I can't imagine you convincing anybody that this is some sort of objective review of his work. You hate this book. You mock it. It is perhaps deserving of these things from your point of view.

My opinion is that you could save quite a bit of money and unnecessary histrionics by simply contacting this guy, explaining to him in a rational(rather than condescending) manner, why you don't like his book, and why you decided to lash out to such a degree that he was insulted. Apologize for being insulting, as being insulting is completely unnecessary, in any instance, really. What purpose does it serve besides your own?

I bother to post this because I really don't think that this battle has any real relevance, it is just a feud between two people. I would hate to see this little dispute be the symbolic battle of 'Freedom of Speech' on the internet or something, where all the bloggers are following it etc. This shouldn't be a story. This isn't a battle between 'reason' and 'faith' that will teach us all a lesson and be remembered. This is just a flame war that has extended into real life. Only a very, very small percentage of the people in the world would even be able to make sense of this situation. The only useful function of this situation is to create publicity for both parties, which is of no advantage to anyone but them and their lawyers.

Just drop it PZ, you are an unconvincing martyr. Diffuse the situation, don't start a crusade, and get back to what you are supposed to be doing, of which stating your opinions is just a part.

This "Stuart Pivar" sounds like that native american indian tribe that was trying to legally claim that they invented Linux and were trying to claim intellectual property on Linux. If anyone remembers that case I cannot recall the name.

I hope this case results in really good publicity for Myers and a lot of anguish and distress for the unoriginal Stuart Pivard.

Y'know, the mere fact of the lawsuit doesn't prove anything about the tone of PZ's review, nor about Pivar's motivations for the lawsuit. Sometimes, people get sued for no good reason. And they're supposed to be innocent until proven guilty in any case.

I also like the idea that PZ is supposed to contact Pivar and explain politely why his book is unscientific and irrational. Yeah, that oughta calm him down, alright.

Don't know what line of work you're in, but I hope to god it's not mediation.

Sorry, this guy is claiming to be a scientist.
If you claim to be a scientist, you do not sue hostile critics. You refute them by the power of your superior scientific discourse. You hold them up to ridicule because they do not know what they are talking about.
Going to court about a matter of scientific debate is like taking RealClimate to court because they are rude about global warming sceptics.

I'm afraid I was Teleologically programed to believe in Teleology. ;-)

Or to quote someone else that must infuriate many:

The idea of God is an absolutely necessary function of an irrational nature, which has [absolutely] nothing to do with the question of God's existence. - Karl Jung, 1991

What purpose faith?

I like your web site, but I'd suggest a reading of Karl Popper's "Conjecture and Refutation" by some of your corespondents before I'd ever publically claim to know something about the Philosophy of Science. I assume they've all read Thomas Kuhn. The list does get rather long, if you really do have an interest: Russell, Whitehead, Chomsky... Hell, Spinoza should keep you occupied for a few months, at least. Kant should still
