Philip Ball's new book: "How Life Works"

Philip Ball has just published a new book "How Life Works." The subtitle is "A User’s Guide to the New Biology" and that should tell you all you need to know. This is going to be a book about how human genomics has changed everything.

Gert Korthof reviews my book

Gert Korthof thinks that the current view of evolution is incomplete and he's looking for a better explanation. He just finished reading my book so he wrote a review on his blog.

Scientists say: 90% of your genome is junk. Have a nice day! Biochemist Laurence Moran defends junk DNA theory

The good news is that I've succeeded in making Gert Korthof think more seriously about junk DNA and random genetic drift. The bad news is that I seem to have given him the impression that natural selection is not an important part of evolution. Furthermore, he insists that "evolution needs both mutation and natural selection" because he doesn't like the idea that random genetic drift may be the most common mechanism of evolution. He thinks that statement only applies at the molecular level. But "evolution" doesn't just refer to adaptation at the level of organisms. It's just not true that all examples of evolution must involve natural selection.

I think I've failed to explain the null hypothesis correctly because Korthof writes,

It's clear this is a polemical book. It is a very forceful criticism of ENCODE and everyone who uncritically accepts and spreads their views including Nature and Science. I agree that this criticism is necessary. However, there is a downside. Moran writes that the ENCODE research goals of documenting all transcripts in the human genome was a waste of money. Only a relatively small group of transcripts have a proven biological function ("only 1000 lncRNAs out of 60,000 were conserved in mammals"; "the number with a proven function is less than 500 in humans"; "The correct null hypothesis is that these long noncoding RNAs are examples of noisy transcription", or junk RNA"). Furthermore, Moran also thinks it is a waste of time and money to identify the functions of the thousands of transcripts that have been found because he knows its all junk. I disagree. The null hypothesis is an hypothesis, not a fact. One cannot assume it is true. That would be the 'null dogma'.

That's a pretty serious misunderstanding of what I meant to say. I think it was a worthwhile effort to document the number of transcripts in various cell types and all the potential regulatory sequences. What I objected to was the assumption by ENCODE researchers that these transcripts and sites were functional simply because they exist. The null hypothesis is no function and scientists must provide evidence of function in order to refute the null hypothesis.

I think it would be a very good idea to stop further genomic surveys and start identifying which transcripts and putative regulatory elements are actually functional. I'd love to know the answer to that very important question. However, I recognize that it will be expensive and time consuming to investigate every transcript and every putative regulatory element. I don't think any lab is going to assign random transcripts and random transcription factor binding sites to graduate students and postdocs because I suspect that most of those sequences aren't going to have a function. If I were giving out grant money I give it to some other lab. In that sense, I believe that it would be a waste of time and money to search for the function of tens of thousands of transcripts and over one million transcription factor binding sites.

That not dogmatic. It's common sense. Most of those transcripts and binding sites are not conserved and not under purifying election. That's pretty good evidence that they aren't functional, especially if you believe in the importance of natural selection.

There's lot more to his review including some interesting appendices. I recommend that you read it carefully to see a different perspective than the one I adocate in my book.

Wikipedia vs experts and a proposal for "arbitrators"

Wikipedia is a not-for-profit crowdsourced encyclopedia that's open to anybody who wants to contribute. This is both a strength and a weakness but the weaknesses are becoming important in an age of fake news and misinformation. The rules of Wikipedia mean that amateurs can insert any information into science articles as long as it is backed by a reliable source. But "reliable sources" include the popular press and books that may or may not report the scientific consensus accurately. When knowledgeable experts try to correct information, or put it into the proper context, they are often opposed by Wikipedia administrators who have a built-in bias against experts—a bias that's not entirely unjustified but much abused. Consequently, scientists often get frustrated trying to deal with the rules and traditions of Wikipedians because these rules are very different than the standards in the scientific community.

Here's an interesting article by Piotr Konieczny on From Adversaries to Allies? The Uneasy Relationship between Experts and the Wikipedia Community.

Of mice and Michael

Michael Behe has published a book containing most of his previously published responses to critics. I was anxious to see how he dealt with my criticisms of The Edge of Evolution but I was disappointed to see that, for the most part, he has just copied excerpts from his 2014 blog posts (pp. 335-355).

I think it might be worthwhile to review the main issues so you can see for yourself whether Michael Behe really answered his critics as the title of his most recent book claims. You can check out the dueling blog posts at the end of this summary to see how the discussion evolved in real time more than four years ago.

Many Sandwalk readers participated in the debate back then and some of them are quoted in Behe's book although he usually just identifies them as commentators.

My Summary

Michael Behe has correctly indentified an extremely improbably evolution event; namely, the development of chloroquine resistance in the malaria parasite. This is an event that is close to the edge of evolution, meaning that more complex events of this type are beyond the edge of evolution and cannot occur naturally. However, several of us have pointed out that his explanation of how that event occurred is incorrect. This is important because he relies on his flawed interpretation of chloroquine resistance to postulate that many observed events in evolution could not possibly have occurred by natural means. Therefore, god(s) must have created them.

In his response to this criticism, he completely misses the point and fails to understand that what is being challenged is his misinterpretation of the mechanisms of evolution and his understanding of mutations.


The main point of The Edge of Evolution is that many of the beneficial features we see could only have evolved by selecting for a number of different mutations where none of the individual mutations confer a benefit by themselves. Behe claims that these mutations had to occur simultaneously or at least close together in time. He argues that this is possible in some cases but in most cases the (relatively) simultaneous occurrence of multiple mutations is beyond the edge of evolution. The only explanation for the creation of these beneficial features is god(s).

More misconceptions about junk DNA - what are we doing wrong?

I'm actively following the views of most science writers on junk DNA to see if they are keeping up on the latest results. The latest book is DNA Demystified by Alan McHughen, a molecular geneticist at the University California, Riverside. It's published by Oxford University Press, the same publisher that published John Parrington's book the deeper genome. Parrington's book was full of misleading and incorrect statements about the human genome so I was anxious to see if Oxford had upped it's game.1, 2

You would think that any book with a title like DNA Demystified would contain the latest interpretations of DNA and genomes, especially with a subtitle like "Unraveling the double Helix." Unfortunately, the book falls far short of its objectives. I don't have time to discuss all of its shortcomings so let's just skip right to the few paragraphs that discuss junk DNA (p.46). I want to emphasize that this is not the main focus of the book. I'm selecting it because it's what I'm interested in and because I want to get a feel for how correct and accurate scientific information is, or is not, being accepted by practicing scientists. Are we falling for fake news?

Sloppiness in translation initiation

There are two competing worldviews in the fields of biochemistry and molecular biology. The distinction was captured a few years ago by Laurence Hurst commenting on pervasive transcription when he said, "So there are two models; one, the world is messy and we're forever making transcripts we don't want. Or two, the genome is like the most exquisitely designed Swiss watch and we don't understand its working. We don't know the answer—which is what makes genomics so interesting." (Hopkins, 2009).

I refer to these two world views as the Swiss watch analogy and the Rube Goldberg analogy.

The distinction is important because, depending on your worldview, you will interpret things very differently. We see it in the debate over junk DNA where those in the Swiss watch category have trouble accepting that we could have a genome full of junk. Those in the Rube Goldberg category (I am one) tend to dismiss a lot of data as just noise or sloppiness.

Birth and death of genes in a hybrid frog genome

De novo genes1 are quite rare but genome duplications are quite common. Sometimes the duplicated regions contain genes so the new genome contains two copies of a gene that was formerly present in only one copy. "Common" in this sense means on a scale of millions of years. Michael Lynch and his colleague have calculated that the rate of fixed gene duplication is about 0.01 per gene per million years (Lynch and Conery, 2003 a,b; Lynch 2007). Since a typical vertebrate has more than 20,000 genes, this means that 200 genes will be duplicated and fixed every million years.


The initial duplication event is likely to be deleterious since there will now be redundant DNA in the genome. The slightly deleterious allele (duplication) can be purged by negative selection in species with large population sizes (e.g. bacteria). But in species with smaller populations, natural selection is not powerful enough to eliminate slightly deleterious alleles so the duplication persists and may become fixed in the population.

Intelligent Design Creationists reveal their top story of 2016

Yesterday I posted an article on: Creationists list the top ten stories of 2016 . Some of you may have noticed that there were only nine stories. That's because Evolution News & Views didn't post their top story until today. I was pretty sure what it would be.

Let me remind you of the main point I made yesterday. Intelligent Design Creationists claim to have scientific evidence of intelligent design. They claim their movement is focused on demonstrating intelligent design but not on proving anything about who the designer might be.

But that's not what the movement is all about. Most of their writings and speeches are focused on attacking evolution. They hope that by discrediting evolution and science they will, by default, support the case for gods (false dichotomy). They also hope that by promoting gaps in our knowledge they will lend support to those who want to insert gods into the gaps.

You don't need to take my word for it. Just look at what they think are the top stories of 2016. Most of their top nine stories were critiques of science in one way or another. There wasn't a single top story that advanced the case for intelligent design.

So, what about the #1 story? Is it going to be different?

Creationists list the top ten stories of 2016

Intelligent Design Creationists are still trying to promote their views. They consistently claim to have positive evidence of intelligent design and they consistently complain whenever we point out what they actually do; they attack evolution/science. Their main talking point relies on the fallacy known as "false dichotomy." They assume that by casting doubt on evolution/science they lend support to their religious viewpoint.

Each year, the IDiots on Evolution News & Views (sic) publish their top ten stories. The series is linked to a fund-raising campaign so it's safe to assume they think these stories advance their cause. Let's see how many of the top stories promote intelligent design and how many are just criticisms of evolution/science. That should be revealing ...

Nature opposes misinformation (pot, kettle, black)

The lead editorial in last week's issue of Nature (Dec. 8, 2016) urges us to Take the time and effort to correct misinformation. The author (Phil Williamson) is a scientist whose major research interest is climate change and the issue he's addressing is climate change denial. That's a clear example of misinformation but there are other, more subtle, examples that also need attention. I like what he says in the opening paragraphs,

Most researchers who have tried to engage online with ill-informed journalists or pseudoscientists will be familiar with Brandolini’s law (also known as the Bullshit Asymmetry Principle): the amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it. Is it really worth taking the time and effort to challenge, correct and clarify articles that claim to be about science but in most cases seem to represent a political ideology?

I think it is. Challenging falsehoods and misrepresentation may not seem to have any immediate effect, but someone, somewhere, will hear or read our response. The target is not the peddler of nonsense, but those readers who have an open mind on scientific problems. A lie may be able to travel around the world before the truth has its shoes on, but an unchallenged untruth will never stop.
I've had a bit of experience trying to engage journalists who appear to be ill-informed. I've had little success in convincing them that their reporting leaves a lot to be desired.

I agree with Phil Williamson that challenging falsehoods and misrepresentation is absolutely necessary even if it has no immediate effect. Recently I posted a piece on the misrepresentations of the ENCODE results in 2007 and pointed a finger at Nature and their editors [The ENCODE publicity campaign of 2007]. They are responsible because they did not ensure that the main paper (Birney et al., 2007) was subjected to appropriate peer review. They are responsible because they promoted misrepresentations in their News article and they are responsible because they published a rather silly News & Views article that did little to correct the misrepresentations.

That was nine years ago. Nature never admitted they were partly to blame for misrepresenting the function of the human genome.

The ENCODE publicity campaign of 2007

ENCODE1 published the results of a pilot project in 2007 (Birney et al., 2007). They looked at 1% (30Mb) of the genome with a view to establishing their techniques and dealing with large amounts of data from many different groups. The goal was to "provide a more biologically informative representation of the human genome by using high-throughput methods to identify and catalogue the functional elements encoded."

The most striking result of this preliminary study was the confirmation of pervasive transcription. Here's what the ENCODE Consortium leaders said in the abstract,
Together, our results advance the collective knowledge about human genome function in several major areas. First, our studies provide convincing evidence that the genome is pervasively transcribed, such that the majority of its bases can be found in primary transcripts, including non-protein-coding transcripts, and those that extensively overlap with one another.
ENCODE concluded that 93% of the genome is transcribed in one tissue or another. There are two possible explanations that account for pervasive transcription.

Revisiting Michael Behe's challenge and revealing a closed mind

It's been twenty years since Michael Behe published Darwin's Black Box and Intelligent Design Creationists are flagellating themselves over the fact that it had so little impact on creationism. The USA is becoming more secular with each passing year. Religion is on the decline.

In their attempt to deal with their defeat, the main ID blog has been publishing "Behe's Greatest Hits," which is a euphemistic way of saying "Behe's Greatest Failures." The latest one caught my eye. It's Best of Behe: An Open Letter to Professors Kenneth Miller and PZ Myers.

It takes you back more than two years to July 21, 2014. That's when Michael Behe issued his challenge to PZ Myers and Ken Miller. The challenge was based on his book The Edge of Evolution and specifically on the development of chloroquine resistance in Plasmodium falciparum. Behe starts with the assumption that cloroquine resistance is extremely rare—it occurs with a probability of roughly 10-20. He concludes that resistance requires at least two different mutations that must occur simultaneously in an individual suffering from malaria while being treated with chloroquine.

The first assumption is approximately correct. Chloroquine resistance is rare. He was criticized for the second assumption; namely, that the overall probability of chloroquine resistance is just the probability of two mutations occurring simultaneously (e.g. 10-10 × 10-10 = 10-20).

Atheism is a catastrophe for science according to Michael Egnor

Michael Egnor doesn't like atheists. He got a bit upset about a recent post by PZ Myers so he responded on Evolution News & Views (sic) with: Atheism Is a Catastrophe for Science.

Modern theoretical science arose only in the Christian milieu. Roger Bacon, Copernicus, Galileo, Newton, Kepler, Faraday, Pasteur, Maxwell and countless other pioneers of the Scientific Enlightenment were fervent Christians who explicitly attributed the intelligibility in nature to God's agency, and even 20th-century scientists like Einstein and Heisenberg and Schrodinger and Rutherford and Planck attributed nature to intelligent agency. Einstein famously explained his quest: "I want to know God's thoughts..."

Vanishingly few great scientists have attributed the world to "undirected processes." Atheism, in fact, has a dismal record in science. For much of the 20th century, a third of humanity lived under the boot of atheist ideology. What was the great science produced by atheist scientists in the Soviet Union? What are the scientific contributions of Communist China and Cuba and Vietnam and Albania? Compare the scientific output of East Germany (atheist) to that of West Germany (Lutheran and Catholic). Compare the scientific output of North Korea (atheist) to that of South Korea (Christian and Buddhist).

The fact is that during the 20th century atheist ideological systems that "assum[ed] that the world is a product of natural, undirected processes" governed a third of humanity. What's the scientific "track record" of atheism? Atheism had its run: it heralded a scientific dark age in any nation unfortunate enough to fall under its heel. Atheism is as much a catastrophe for science as it is a catastrophe for humanity. The only thing atheist systems produced reliably (and still produce reliably) is corpses.
Google is my friend. I found a Wikipedia article on List of nonreligious Nobel Laureates. Here are the Nobel Laureates in science who didn't believe in any gods. This is part of the "scientific track record of atheism."

Understanding Michael Behe's edge of evolution

It's been about twenty years since Intelligent Design Creationism rose to prominence. Just last week the Center for Science and Culture celebrated it's 20th birthday [Twenty Years Ago Today, Did This Change the Evolution Debate Forever?]. In all that time, the best that ID proponents can come up with is some work by Michael Behe that attempts to discredit evolution.

The first book by Behe was Darwin's Black Box where he developed the notion of irreducible complexity. The definition of irreducible complexity has changed over the years but the basic idea is that some biological structures are very complex and the removal of any one part will render the complex nonfunctional. This presents an enormous problem for evolution, according to Behe, because all the presumptive intermediates will be nonfunctional.

The conclusion is that it's impossible to evolve an irreducibly complex structure. Evolutionary biologists have no problem accepting the existence of irreducibly complex structures. They see them all the time. What they object to is the idea that irreducibly complex structures cannot have arisen by evolution. Behe's conclusion has been shown to be false and he has admitted on multiple occasions that irreducibly complex structures can arise by purely natural means (evolution).

Michael Denton discusses the "hierarchy of nature"

Here's a video where Michael Denton describes his view of biology. The main point is that he cannot think of a way for evolution to produce the "hierarchy of nature." Therefore goddidit there must be some other explanation.

The Discovery Institute made the video. David Klinghoffer describes it on Evolution News & Views (sic): Conversations with Dr. Denton: The Hierarchy of Nature. Klinghoffer says,
Darwinism, honestly regarded, should lead you to expect not an ordered, increasingly inclusive hierarchy of life but more like a disordered...smear of diversity. Such expectations are frustrated by reality. As biologist Michael Denton explains, life presents itself as a tiered formation marked by novelties or homologs. These taxa-defining novelties, such as the pentadactyl limb, are not lead up to by a series of forms increasingly like the final version.

That's strike one. Worse for Darwinism, it's typically the case that there is no way even to imagine how the novelty could be lead up to in such a manner. Strike two. Watch and enjoy.

This is what a strawman looks like

This is another post about the stupidity of Intelligent Design Creationists. Stop reading if you don't need any more convincing.

Today is Darwin Day. It's the anniversary of the birth of Charles Darwin (Feb. 12, 1809 - April 19, 1882).

This is not a happy day for the Discovery Institute so they've put up a series of posts on Evolution News & Views (sic) to discredit Darwin and "Darwinism."

One of them is by the newly rejuvenated poster boy, Michael Denton: On Darwin Day, Darwinism Is Well Past Its "Sell By" Date. Here's the part I want you to see,
To understand the core weakness of the Darwinian worldview, it is important to understand what Darwinian natural selection requires. The process will work its magic, building up functional structures in organisms, only when two very strict conditions are met: First, the structure must be adaptive—that is, helpful to the organism in flourishing in its environment—and second, there must be a continuum of structures, functional all along the way, leading from an ancestor species to the descendent.

That is, the thing we are trying to explain must in some way help the creature survive, and between the creature and the creature's ancestor there must be a gradual change, each step of which is stable and enhances fitness, or success in reproduction.
Strictly speaking, that's a reasonable explanation of Darwinism as most evolutionary biologists understand it. But here's the problem. There aren't very many evolutionary biologists who are strict Darwinists these days even though there are many who tilt strongly in that direction.

Intelligent Design Creationism and the fine-tuning argument

Michael Denton and the Discovery Institute are promoting his new book, Evolution: Still a Theory in Crisis. I haven't yet read the book. I ordered from Amazon.ca and I won't get it until March.

Denton tries to explain the connection between the fine-tuning argument and structuralism in a recent post on Evolution News & Views: Natural Life: Cosmological Fine-Tuning as an Argument for Structuralism. I've dealt with structuralism already [What is "structuralism"?] so let's think about fine tuning.

The essence of the fine-tuning argument is that the basic laws of physics and chemistry are so precise that even slight changes would result in a universe where life is impossible. The focus is usually on the fundamental constants such as the speed of light and the charge on an electron. I don't know enough about physics to evaluate the argument that these are fine-tuned so I have to rely on physicists to inform me.

Targets, arrows, and the lottery fallacy

Sandwalk readers have been discussing the way Intelligent Design Creationists have been calculating probabilities [see Intelligent Design Creationists are very confused about epigenetics and Waiting for multiple mutations: Michael Lynch v. Michael Behe].

We've known for a long time that the most common mistake is assuming that there's only one solution to a problem. They see an end result, like a bacterial flagellum, or resistance to malaria, or the binding of two proteins, and assume that a few very specific mutations had to occur in a specific sequence in order to produce that result.

judmarc calls this the "lottery fallacy" and I think it's a good term [see lottery fallacy],
This is of course what I like to call the "lottery fallacy." It's used by virtually every ID proponent to produce erroneously inflated probabilities against evolution.

Lottery fallacy: The odds against any *particular individual* winning the PowerBall lottery are ~175 million to 1. But there were three winners just last night. That's because *someone* winning the PowerBall is not an especially rare occurrence. It happens every few weeks throughout the year.

In exactly the same way, Axe, Gauger, Behe, and the rest of the ID folks always base their math on the chances that a *particular* neutral or beneficial mutation will occur, and just as with the lottery, the chances of a *particular* outcome are utterly minuscule. The occurrence of *some* neutral or beneficial mutation, however, is, as with the lottery, so relatively common as to be completely unremarkable.

To summarize: ID proponents misuse probability math to make the common appear impossible.
As it turns out, someone on Evolution News & Views (sic) just posted an excellent example of this fallacy [Intelligent Design on Target]. Here's what he/she/it says,
In his second major treatise on design theory, No Free Lunch: Why Specified Complexity Cannot Be Purchased without Intelligence, William Dembski discusses searches and targets. One of his main points is that the ability to reach a target in a vast space of possibilities is an indicator of design. A sufficiently complex target that satisfies an independent specification, he argues, creates a pattern that, when observed, satisfies the Design Filter. There are rigorous mathematical and logical proofs of this concept in the book, but at one point, he uses an illustration even a child can understand.
Consider the case of an archer. Suppose an archer stands fifty meters from a large wall with a bow and arrow in hand. The wall, let us say, is sufficiently large that the archer cannot help but hit it. Now suppose each time the archer shoots an arrow at the wall, the archer paints a target around the arrow so that the arrow sits squarely in the bull's-eye. What can be concluded from this scenario? Absolutely nothing about the archer's ability as an archer. Yes, a pattern is being matched; but it is a pattern fixed only after the arrow has been shot. The pattern is thus purely ad hoc. [No Free Lunch, pp. 9-10, emphasis added.]
Most people have experience with target shooting of some kind, whether with bows and arrows, guns (including squirt guns), snowballs, darts, or most sports like baseball, soccer, basketball, hockey, and football. Children laugh when they picture an archer who "couldn't even hit the broadside of a barn" and rushes up to the arrow and paints a bull's-eye around it. Grown-ups might compare that to a biologist looking at an irreducibly complex biological system and simply stating, "It evolved." In each of these cases, Dembski would say that since the pattern was not independently specified, therefore it is ad hoc.
The unknown author included the image shown above in order to illustrate the point (Image: © Kagenmi / Dollar Photo Club).

Do you see the fallacy? Just because we observe a complex adaptation or structure does NOT mean that it was specified or pre-ordained. There are certainly many different structures that could have evolved—most of them we never see because they didn't happen. And when a particular result is observed it doesn't mean that there was only one pathway (target) to producing that structure.

To continue the analogy—at the risk of abusing it—there may be hundreds of targets in the woods and most of them have very large bullseyes. Imagine you're out for a walk in the woods and you see that almost every tree has a big target with a large bullseye. You find an arrow stuck at the edge of one of the bullseyes and lots of arrows stuck in the trees, the ground, and parts of most of the targets outside of the central bullseyes. Would you write a book about how good the archer must have been?

Waiting for multiple mutations: Intelligent Design Creationism v. population genetics

Casey Luskin is worried about university students. Apparently, they aren't getting enough correct information about intelligent design. Luskin uses the example of a student named Michael Heckle at Iowa State University. Mr. Heckel said; "So far, there has been no research done by intelligent design advocates that has led to any sort of scientific discovery."

This happens to be a true statement but Casey Luskin takes exception in a blog post that appeared the other day on Evolution News & Views (sic) [No ID Research? Let's Help Out This Iowa State Student].

Did Kitzmiller v. Dover kill Intelligent Design Creationism?

The 10th anniversary of Judge Jone's decision in Kitzmiller v. Dover is coming up on Dec. 20, 2015. See the post at Panda's Thumb: Kitzmas is Coming!.

ID proponents are also marking the event in various ways. If you are interested in the discussion, you should read the posts on Evolution News & Views covering the Ten Myths about Dover. The first one (#10) is Ten Myths About Dover: #10, "The Intelligent Design Movement Died After the Dover Decision".

Of course the ID movement didn't die after Kitzmiller v. Dover. From the outside (i.e. not in the USA) it seems to be as strong as ever. State legislatures all over America are still trying to suppress the teaching of evolution and promote creationist perspectives. The movement has captured the attention of many (most?) prominent politicians and much of the American public still believes that scientists are wrong about evolution.
