Evolution driven by laws? Not random mutations?

So claims a recent book, Arrival of the Fittest, by Andreas Wagner, professor of evolutionary biology at U Zurich in Switzerland (also associated with the Santa Fe Institute). He lectures worldwide and is a fellow of the American Association for the Advancement of Sciences.

From the book announcement:

Can random mutations over a mere 3.8 billion years solely be responsible for wings, eyeballs, knees, camouflage, lactose digestion, photosynthesis, and the rest of nature’s creative marvels? And if the answer is no, what is the mechanism that explains evolution’s speed and efficiency?

In Arrival of the Fittest, renowned evolutionary biologist Andreas Wagner draws on over fifteen years of research to present the missing piece in Darwin’s theory. Using experimental and computational technologies that were heretofore unimagined, he has found that adaptations are not just driven by chance, but by a set of laws that allow nature to discover new molecules and mechanisms in a fraction of the time that random variation would take.

From a review (which is careful to note that it is not a religious argument):

The question “how does nature innovate?” often elicits a succinct but unsatisfying response – random mutations. Andreas Wagner first illustrates why random mutations alone cannot be the cause of innovations – the search space for innovations, be it at the level of genes, protein, or metabolic reactions is too large that makes the probability of stumbling upon all the innovations needed to make a little fly (let alone humans) too low to have occurred within the time span the universe has been around.

He then shows some of the fundamental hidden principles that can actually make innovations possible for natural selection to then select and preserve those innovations.

Like interacting parallel worlds, this would be momentous news if it is true. But someone is going to have to read the book and assess the strength of the laws advanced.

One thing for sure, if an establishment figure can safely write this kind of thing, Darwin’s theory is coming under more serious fire than ever. But we knew, of course, when Nature published an article on the growing dissent within the ranks about Darwinism.

In origin of life research, there has long been a law vs. chance controversy. For example, Does nature just “naturally” produce life? vs. Maybe if we throw enough models at the origin of life… some of them will stick?

Note: You may have to apprise your old schoolmarm that Darwin’s theory* is “natural selection acting on random mutations,” not “evolution” in general. It is the only theory that claims sheer randomness can lead to creativity, in conflict with information theory. See also: Being as Communion.

*(or neo-Darwinism, or whatever you call what the Darwin-in-the-schools lobby is promoting or Evolution Sunday is celebrating).*

Keith, you forgot to emphasize last sentence: "There's rhyme and reason to how life evolved." ID thrives on rhyme and reason. Mountains of evidence for rhyme and reason.ppolish

Thorton:
volution doesn’t have to search the ginormous whole universe search space looking for innovations. All it does in each new generation is search the space immediately surrounding the existing working copy. If it finds a small improvement, it keeps it.
tjguy:
We have organism A living in say, the eastern half of the US. Up in Maine, a particularly helpful mutation happened. The organisms living in Maine did not have to search the whole population of organism A that lived in the eastern half of the US to benefit from that mutation. They found it in their own backyard. Then slowly over time, that mutation spread and became established in the whole population of organism A all over the eastern half of the US. Then a mutation happened in PA and the same thing happened. And this continued until the organism evolved into a new kind of organism? I’m probably not tracking with you 100%. Can you please explain for me what you mean more clearly?
tjguy, Thorton isn't talking about physical space; he's talking about an abstract search space. Every genotype can be visualized as occupying a point in a many-dimensional genetic space. Evolution over time then amounts to following a trajectory in this space. Thorton's point is that evolution doesn't search the entire space; it just searches the the tiny portion of the space that is accessible via mutations from the current location.keith s

Denyse, Why are your journalistic standards so lax? In less than ten minutes of searching, I found this interview:
World Science Festival: We’ve all heard of ‘survival of the fittest.’ What does ‘arrival of the fittest’ mean? Andreas Wagner: It’s actually taken from a famous botanist, Hugo de Vries, from the last sentence of a book he wrote in 1905: “Natural selection can explain the survival of the fittest, but it cannot explain the arrival of the fittest.” The arrival of the fittest here simply means how new traits originate. For example, there is this interesting fish called the winter flounder, which lives close to the Arctic Circle, in very deep, cold waters—so cold that our body fluids would freeze solid. Yet this fish survives there. It turns out that its ancestors discovered a new class of antifreeze proteins that work a bit similar to the antifreeze in your car. It’s very easy to understand how natural selection could help such an innovation spread through a population of fish, since it helps them survive; but it doesn’t tell us anything about how the innovation arose in the first place. That’s a puzzle that’s been with us since Darwin’s time. WSF: So is it all down to random chance—genes get juggled, and stuff arises? AW: There’s a whole lot more to it. Random chance still plays a role—we know that the DNA of organisms changes randomly. But there’s actually an organization process that helps these organisms discover new things. Think of a library that is so large that it contains all possible strings of letters. Each volume in this library contains a different string, and there would be many more volumes than there are atoms in the universe. We could call that a universal library. It would contain a lot of nonsense, but it would also contain a lot of interesting texts—your biography, my biography, the life story of every human who’s been alive, the political history of every country, all novels ever written. And it would also contain descriptions of every single technological innovation, from fire to the steam engine, to innovations we haven’t made yet. Nature innovates with libraries much like that one. A protein is basically a string of letters, corresponding to one of 20 different kinds of amino acid building blocks in humans. A single protein could be 100 amino acids. So we can think of a library of all possible amino acid texts. When evolution changes organisms, what it does is explore this library through random changes in DNA, which are then translated by organisms into changes in the amino acid sequences of proteins. A population is like a crowd of readers that goes from one text to the next. Now, how would you organize a library if you wanted to easily find the text on a particular technology? You would have a catalog, and have all the texts about, say, transistors in one section of the library. That works for us because we can read catalogs, but in nature’s library it’s very different. Evolution doesn’t have a catalog; its readers explore the library through random steps. There’s also something that’s very curious about this library. You think of antifreeze proteins as being a solution to a very specific problem that nature faces: “How do I keep this fish alive?” You may think there is only one single solution to this, one amino acid strain that provides this protection. But if that were the case, evolution would have a serious problem, because the library is so huge it could never be explored in the 4 billion years life has been around, or even 40 billion years. But it turns out there is not just one text that solves the problem, there are myriad texts that all have a different amino acid sequence specifying antifreeze protection. And these texts are not clustered in one corner of the library; they’re spread out all over… WSF: So you’re more likely to run into it! AW: Exactly. This particular organization also helps because when you, as a reader in a library of books, pick up a text that doesn’t have any meaning, you’d put it aside. But in evolution’s libraries that’s completely different: if an organism has an antifreeze protein, and a single mutation changes the sequence and disrupts the function of the protein, it becomes useless and the organism dies. Missteps in nature’s libraries are fatal. A large network of synonymous texts ensures that nature’s readers can stay on a path that specifies, say, antifreeze function. This network organization buys an additional benefit: As a population explores the library, near the network of synonymous texts you might find new innovations—superior antifreeze proteins, perhaps. So the peculiar organization of this library allows blind exploration, the preservation of things that work already, and the discovery of new things that allows the arrival of the fittest. WSF: What’s the main thing you want readers to take away from the book? AW: That there’s a fascinating world out there that Darwin didn’t have any idea about, and that really helps us explain how evolution can work. Evolution has been criticized from various quarters by people who say, “well, it can’t all just be random change.” The book shows principles that are in agreement with Darwinism, but go beyond it. There’s rhyme and reason to how life evolved. [Emphasis added]
There is nothing anti-Darwinian about Wagner's thesis. DNA changes randomly, as he stresses. It's nothing but selection working on random mutations. Wagner just adds -- and this is not original to him, by any means -- that the fitness landscape isn't limited to one solution per problem. We knew that already, though IDers like kairosfocus try to downplay it with their "islands of function" rhetoric. Which makes this statement of yours ridiculous:
One thing for sure, if an establishment figure can safely write this kind of thing, Darwin’s theory is coming under more serious fire than ever.
You fell for the hype in the book announcement, and didn't bother to do the ten extra minutes of research that would have saved you from embarrassment.keith s

Thorton says:

My question is this: How do you know that such "innovations" even exist? How do you know that there are enough innovations in the immediate surrounding to take the organism to the next lever? How do you know that an evolutionary pathway from A to B even exists anywhere in space? I would think that searching the immediate area would severely handicap an organism because the chances of an innovation existing would be greatly lowered. Let me see if I understand what you are trying to say. We have organism A living in say, the eastern half of the US. Up in Maine, a particularly helpful mutation happened. The organisms living in Maine did not have to search the whole population of organism A that lived in the eastern half of the US to benefit from that mutation. They found it in their own backyard. Then slowly over time, that mutation spread and became established in the whole population of organism A all over the eastern half of the US.

Interesting. “Renowned evolutionary biologist Andreas Wagner
By whom was he renowned? Certainly not by anyone I know. Do you believe all the over-the-top hyperbole you read on every publisher's advertisements? Why do you think a scientific PhD can't have the occasional crackpot idea?
More seriously, you might consider engaging scientists like Mr. Wagner to try to convince him/them of his errors
When scientists like Mr. Wagner publish their results in the proper peer reviewed scientific journals I will. When they publish in the popular press with GEE!! WOW!! PARADIGM CHANGING!! all over the dust jacket I tend to roll my eyes.Thorton

Some sort of built-in evolvability might be the next sort of explanation. It's similar to self-organizational principles. It answers the question of "why do organisms want to survive"?Silver Asiatic

Oh please, not the zombified remains of this stupid Creationist argument again.
Interesting. "Renowned evolutionary biologist Andreas Wagner" was somehow convinced by stupid Creationists and he turned against Darwin. Yes, I can see why Creationists are such a threat to science. Their arguments end up convincing renowned evolutionists. It could be some sort of creationist mind-control.
Good Lord but there are some moronic crackpots out there.
And some of them are "renowned evolutionary biologists" apparently. More seriously, you might consider engaging scientists like Mr. Wagner to try to convince him/them of his errors. While I can understand your frustration, I'd think you'd want to express it to him and his editors/publishers rather than here. I mean he's working in your own field of study so there should be some common ground to build on.Silver Asiatic

Given reductionism, these "laws" have to be physical or chemical laws. So they're newly discovered properties or results of chemical interactions? As News says, however, it doesn't matter. What chance does Mr Wagner have of convincing the entire Darwinian-world that he found the 'hidden principles' that guide evolution? The only thing important here is that there's yet another establishment figure dropping a bomb (we like that metaphor lately) on Darwinism. "There are no weaknesses in evolutionary theory". "There is no controversy".Silver Asiatic
