Yes, I'm aware of the fact there's another, possibly better, version of this poster using another word for "crap."

What Is Homeopathy?

 
Homeopathy awareness week is coming up and scientists from all around the world are gearing up to explain why homeopathy doesn't work—that's why it's called "alternative" medicine. It's a part of quack medicine that's not "real" medicine. Real medicine is based on scientific evidence.

Many people don't know what homeopathy is all about. They confuse homeopathy with a host of other forms of non evidence-based medicine like naturopathy and herbalism. That's a big mistake. Homeopathy is a form of treatment where you drink water that supposed to contain the magical imprint of some chemical. The chemical is often quite dangerous but, don't be worried, it's not really present in the treatment you pay for.

Here's the Wikipedia description of homeopathy.

Homeopathy (also spelled homoeopathy or homœopathy) is a form of alternative medicine, first proposed by German physician Samuel Hahnemann in 1796, that attempts to treat patients with heavily diluted preparations. Based on an ipse dixit[1] axiom[2] formulated by Hahnemann which he called the "law of similars", preparations which cause certain symptoms in healthy individuals are given as the treatment for patients exhibiting similar symptoms. Homeopathic remedies are prepared by serial dilution with shaking by forceful striking, which homeopaths term "succussion," after each dilution under the assumption that this increases the effect of the treatment. Homeopaths call this process "potentization". Dilution often continues until none of the original substance remains.

Don't confuse it with anything else. There's absolutely no evidence that homeopathy works. The scientific data, taken as a whole, is conclusive. Be wary of those who believe in homeopathy because their advice on other forms of treatment may not be based on evidence either. Homeopathy is bad enough but it often keeps even worse company.

Should creationism be taught in British classrooms?

 
As most of you know, the citizens of the United Kingdom do not obsess over the separation of church and state and they do not use their constitution to keep creationism out of their schools. That's why the question posed by Michael Reiss in New Statesman is a valid one in that country, "Should creationism be taught in British classrooms?". The answer might surprise many people in other countries.

Why schools and universities should encourage debate on evolution -- and how this could benefit science.
.... When teaching evolution, there is much to be said for allowing students to raise any doubts they have in order to shape and provoke a genuine discussion. The word "genuine" doesn't mean that creationism and intelligent design deserve equal time with evolution. They don't. However, in certain classes, depending on the teacher's comfort with talking about such issues, his or her ability to deal with them, and the make-up of the student body, it can and should be appropriate to address them.

Having said that, I don't pretend to think that this kind of teaching is easy. Some students become very heated; others remain silent even if they disagree profoundly with what is said. But I believe in taking seriously the concerns of students who do not accept the theory of evolution while still introducing them to it. Although it is unlikely that this will help them resolve any conflict they experience between science and their beliefs, good teaching can help students to manage it - and to learn more science.

My hope is simply to enable students to understand the scientific perspective with respect to our origins, but not necessarily to accept it. We can help students to find their science lessons interesting and intellectually challenging without their being a threat. Effective teaching in this area can help students not only learn about the theory of evolution, but also better appreciate the way science is done, the procedures by which scientific knowledge accumulates, the limitations of science and the ways in which scientific knowledge differs from other forms of knowledge.

I agree with this point of view. I think the main arguments for creationism, and against evolution, should be discussed in science class. It's an excellent way of showing what real science is and how it should be practiced.

The problem with ignoring the main criticisms of evolution is that students are going to hear about them from other sources and they won't know what to think about those points of view unless we teach them how to reason. The goal of science education is to teach students how to think, not just fill them with facts. It's our responsibility as teachers to teach critical thinking. One of the best ways to do that is to give them some popular examples to discuss and debate.

Advertising 23andMe

 
Some bloggers are huge fans of genetic testing. They frequently post articles promoting one of the private companies that charge you for doing these tests. ScienceRoll recently posted this video of Anne Wojcicki making a pitch for her company. Wojcicki is one of the co-founders of 23andMe. It's interesting to see how she mixes various rationales for genetic testing with a pitch for 23andMe.

Imagine this was a talk by the CEO of a major pharmaceutical company about the importance of their drugs and why you should buy them. We would probably be more skeptical than we seem to be about Ann Wojcicki. Why is that?

World Homeopathy Awareness Week

 
World Homeopathy Awareness Week takes place next week (April 10-16). This is a week devoted to making people aware of homeopathy and our local Centre for Inquiry and the Committee for Advancement of Scientific Skepticism (CASS) is planning to take full advantage of the opportunity. We'd like everyone to know there's no scientific evidence that supports homeopathic "cures" and, furthermore, the fundamental principle behind homeopathy conflicts with everything we know about modern science.

I urge all bloggers to post something next week in order to let the public know about this scam.

The Canadian Society of Homeopaths also has a number of events planned but I don't think they're talking about the same kind of "awareness."

HOMEOPATHY AND MENTAL WELL-BEING:
BODY AND MIND IN BALANCE
The theme of the 2010 Homeopathy Awareness Month is Homeopathy and Mental Well-being: Body and Mind in Balance. As in previous Awareness celebrations, Registered and Associate members of the Canadian Society of Homeopaths will sponsor events, displays, and special promotions in their communities across Canada.

Time to Leave

 
Canadian troops and support personal have been in Afghanistan for the better part of ten years. The goal was to create a stable democratic state that could offer security to its citizens and promote the rights and values that we cherish in Western democracies.

We aren't any closer to achieving that goal than we were ten years ago. Should Canadian forces remain in Afghanistan after 2011?

There are two main options ....

1. cut and run (withdraw all military forces)
2. soldier on, perhaps with no combat troops

I favor option #1. We've given it our best shot and it's time to admit defeat. Afghanistan is not going to become a respectable member of the world's democratic community.

My resolve was strengthened by a hard-hitting article in last week's issue of Newsweek [The Gang That Couldn't Shoot Straight].

America has spent more than $6 billion since 2002 in an effort to create an effective Afghan police force, buying weapons, building police academies, and hiring defense contractors to train the recruits—but the program has been a disaster. More than $322 million worth of invoices for police training were approved even though the funds were poorly accounted for, according to a government audit, and fewer than 12 percent of the country's police units are capable of operating on their own. Ambassador Richard Holbrooke, the State Department's top representative in the region, has publicly called the Afghan police "an inadequate organization, riddled with corruption." During the Obama administration's review of Afghanistan policy last year, "this issue received more attention than any other except for the question of U.S. troop levels," Holbrooke later told NEWSWEEK. "We drilled down deep into this."

The worst of it is that the police are central to Washington's plans for getting out of Afghanistan. The U.S.-backed government in Kabul will never have popular support if it can't keep people safe in their own homes and streets. Yet in a United Nations poll last fall, more than half the Afghan respondents said the police are corrupt. Police commanders have been implicated in drug trafficking, and when U.S. Marines moved into the town of Aynak last summer, villagers accused the local police force of extortion, assault, and rape.

It's time to leave—the sooner the better. The people of Afghanistan have to want change bad enough to fight for it and that's ain't happening.

Here We Go Again

 
You've been following the battles in the Accommodationist Wars for several years. If you've been paying attention you will by now have acquired a good understanding of the main arguments on both sides. You should be able to recognize which arguments are valid and which ones are false—in terms of their logic.

Now it's time for the test.

Read the following passage by Michael Zimmerman¹ on The Huffington Post. He is defending the proposition that the evolution/creation controversy is not a conflict between science and religion [Redefining The Creation/Evolution Controversy]. Your task is to identify the logical flaw(s) in this argument. For the purposes of this test, we're not interested in who's right and who's wrong in the Accommodationist Wars. I'm just interested in knowing whether you can recognize a good argument and a bad one.

The mere existence of the Clergy Letter Project, an international organization I founded that is comprised of thousands of clergy members and scientists, demonstrates that religious leaders and scientists are not inherently at odds. After all, more than 12,400 Christian clergy members from all across the United States have signed the Christian Clergy Letter, a powerful, two-paragraph statement promoting a shared understanding and acceptance of evolution and Christianity.

What could be clearer than these sentences from that Letter? "Religious truth is of a different order from scientific truth. Its purpose is not to convey scientific information but to transform hearts[...]. We urge school board members to preserve the integrity of the science curriculum by affirming the teaching of the theory of evolution as a core component of human knowledge. We ask that science remain science and that religion remain religion, two very different, but complementary, forms of truth."

Saturday Comics

 
This is the Saturday between Good Friday and Easter Sunday. Denyse O'Leary—your favorite Toronto science writer—tries to lighten your day with a very funny posting on Post-Darwinist and Uncommon Descent [Coffee!! Evolution in action! Check with your local humane society!].

She's responding to the idea that Lenski’s long-term experiment with E. coli has led to bacteria that have "changed shape, changed size, changed metabolism and changed food source."

Denyse replies ...

So the claim is, “changed shape, changed size, changed metabolism and changed food source. How much more MACRO do you expect an organism to evolve?”

Hmmmm. Kittens do this all the time.

Change size? You bet. Goes from a couple of ounces to five lbs in half a year.

Change shape? Sure. The average newborn kitten is just a little bag of mewing metabolism, blind and probably deaf, whose only real talent is using its sense of smell to get control of a teat.

Changed metabolism? Sort of. Kittens must be weaned onto something other than cat milk after about six or seven weeks. I am not a vet, but surely some changes in metabolism accompany this transition.

Changed food source? Yes! From mom cat to local rodents, birds, frogs, and eggs that can be cracked by being pushed off the branch or table. Or, if the cat is under human management, a science-based diet for growing felines. Or otherwise, scavenging a local dumpster. Or whatever an obligate carnivore* like the cat can stomach.

Okay, so where are we now? We have explained how a kitten gets transformed into … a cat.

And this is “evolution”?

Thanks for the comic relief, Denyse. But aren't you worried that someone might think you're serious?

Why Do We Call Them IDiots?

 
Over at Uncommon Descent GilDodgen has A Modest Proposal. It consists mostly of telling scientists what they think about evolution.

“Evolution” is an ill-defined term. It can mean:

1) Change over time.
2) Common ancestry.
3) Random genetic errors filtered by natural selection as the purely materialistic mechanism that explains all of life’s complexity, information content, and information-processing machinery, not to mention human consciousness and its demonstrable creative intelligence.

Change over time is obvious and undeniable. Common ancestry seems reasonable to me, although universal common ancestry appears to be in big trouble with mounting evidence that Darwin’s unidirectional “tree of life” never existed. It might have been something more akin to a hologram than a tree, as far as I can tell.

What Darwinists really want us to accept — without question, dissent, annoying logical/evidential challenges, or apostasy — is definition 3), so let me make a modest proposal to substitute it for “evolution,” and reveal the Darwinian bait-and-switch scam.

This is unbelievable! The standard definition of evolution is in any evolutionary biology textbook and all it takes is a little effort to find it. (If you know how to read.)

What I'd like to know is whether there's any evolutionary biologist who accepts definition #3. Not even the most ardent adaptationist would accept such a silly definition of evolution.

Does Intelligent Design Creationism select for people with very low IQ's or does accepting Intelligent Design Creationism just make you stupid?

Bruce Alberts Wins Vannevar Bush Award

 
Bruce M. Alberts is the winner of the 2010 Vannevar Bush Award for "lifetime contributions to the United States in science and technology" [Biochemist and science education advocate honored for distinguished service in science and technology].

Alberts is a prominent biochemist with a strong commitment to the improvement of science education, and currently serves as editor-in-chief of the journal Science and as a United States science envoy. Alberts is also professor emeritus in the department of biochemistry and biophysics at the University of California, San Francisco, to which he returned in 2005 after serving two six-year terms as the president of the National Academy of Sciences in Washington, D.C.

During his tenure at the National Academies, Alberts was instrumental in developing landmark National Science Education Standards that have been implemented in school systems nationwide. "The type of science as inquiry teaching we need," said Alberts, "emphasizes logical, hands-on problem solving, and it insists on having evidence for claims that can be confirmed by others. It requires work in cooperative groups, where those with different types of talents can discover them--developing self-confidence and an ability to communicate effectively with others."

Alberts is also one of the original authors of The Molecular Biology of the Cell, a preeminent textbook now in its fifth edition. For the period 2000 to 2009, he served as the co-chair of the InterAcademy Council, a new organization in Amsterdam governed by the presidents of 15 national academies of sciences and established to provide scientific advice to the world.

That's Bruce seated front right in a photo from 2007 when he was here to receive an honorary degree. The citation for the Vannevar Bush Award doesn't mention that he was my thesis advisor—it's an unfortunate oversight.

Things You Didn't Know

Patricia J. Wittkopp is a Professor in the Department of Ecology and Evolutionary Biology at the University of Michigan in Ann Arbor. She got her Ph.D. in 2002 with Sean Carroll.

Anything found to be true of E. coli must also be true of elephants.

-Jacques Monod (1954)Wittkopp has just published a paper in PLoS Biology: Variable Transcription Factor Binding: A Mechanism of Evolutionary Change. The second paragraph tells you something you didn't know.

During the last decade, researchers have discovered that the collection of proteins found in different animals is remarkably similar. In fact, many proteins are found not only in animals, but also in fungi and plants; some are even shared with bacteria. This unexpected—and truly astounding—finding has changed scientists' thinking about how biological diversity evolved ...

Isn't that cool? Before 1990, researchers didn't know that many animal proteins had homologs in fungi, plants, and even (gasp!) bacteria.

I presume she means that she didn't know this because she was still in high school.

Cornelius Hunter Says Evolution Is Not a Fact

 
Cornelius Hunter blogs at Darwin's God. He has a Ph.D. in Biophysics and Computational Biology and currently teaches at Biola University. He is a Fellow of the Discovery Institute and the author of several books that I have not read.

Hunter has devoted most of his blogging efforts to attacks on science. This seems to be the most popular strategy of the Intelligent Design Creationists in spite of their claims to the contrary.

His latest posting is Why Evolutionists Say Evolution is a Fact.

Evolutionists say evolution is a fact, every bit as much as gravity is a fact. That is remarkable. We see and even feel gravity everyday. Evolution, on the other hand, entails rather dramatic, one-time, events that were supposed to have occurred long ago, when no one was around to witness them. How could we be sure of such a theory? There must be some extremely powerful and compelling scientific evidence for evolution to make it a fact as gravity is a fact. That is what one would think. But, surprisingly, there is no such evidence. When evolutionists try to explain why evolution is a fact, it is a tremendous anticlimax.

Hunter has not been paying attention. Many of us have written on the subject of evolution as a fact [Evolution Is a Fact and a Theory]. Evidence for the "factness" of evolution is overwhelming. It ranges from evidence that chimps and humans descend from a common ancestor to evidence that the frequencies of alleles are changing in populations as we speak.

That last point is important. Evolution is defined as a change in the frequency of alleles in a population over time and as long as we can demonstrate that change, the fact of evolution can't be disputed. I wonder how Cornelius Hunter explains the differences between the Japanese and the Masai of Kenya and Tanzania? I wonder how he explains the fact that native North Americans are practically homogeneous for O blood type? I wonder how he explains the many studies that have directly tracked heritable change over many generations?

Why are the IDiots so stubborn and so ignorant? Why couldn't Cornelius Hunter demonstrate that he understands why evolution is a fact while disputing some forms of macroevolution? That would be a sensible position. Instead, he comes off looking like an IDiot.

The "Mutationism" Myth I. The Monk's Lost Code and the Great Confusion

This is the second in a series of postings by a guest blogger, Arlin Stoltzfus. You can read the first part at: Introduction to "The Curious Disconnect". Arlin is challenging the status quo in modern evolutionary theory. He's not alone in this challenge but it's important to distinguish between kooks who don't know what they're talking about and serious thinkers who have something to say. Arlin is going to explain to you why everything you thought you knew about mutationism is wrong. I'm happy to give him a chance to post on Sandwalk.

This will be on the exam.

The "Mutationism" Myth I. The Monk's Lost Code and the Great Confusion

The mutationism myth tells the story of how, just over a century ago, the scientific community responded to the discovery of Mendelian genetics by discarding Darwinism, and how Darwinism subsequently was restored.Our journey to explore The Curious Disconnect-- the gap between how we think about evolution and how we might think if we were freed from historical baggage-- begins with the Mutationism Myth. In this, the first of four parts, we are not going to confront any tough scientific or conceptual issues. Instead, we are just going to review an odd story about our intellectual history.

The Mutationism Story

While "myth" has the connotation of falsehood, the story that a myth tells isn't necessarily a false one. The mutationism myth, at least, is anchored in historical events.¹

The mutationism myth tells the story of how, just over a century ago, the scientific community responded to the discovery of Mendelian genetics by discarding Darwinism, and how Darwinism subsequently was restored. The villains of the story are the influential early geneticists or "Mendelians" who saw genetics as a refutation of Darwinism; the heroes are first, the founders of population genetics, theoreticians who sorted everything out in favor of Darwinism by about 1930, and second, the architects of the Modern Synthesis, activists who popularized and institutionalized what we're calling "Darwinism 2.0".

This story has been re-told in secondary sources for nearly 50 years, though I sense that the frequency is decreasing as this episode passes into ancient history. To find examples, try looking up "mutationism" (sometimes "Mendelism" or even "saltationism") in the index of a book about evolution.

I encourage you to consult whatever sources you have and to share the stories that you find. Note that you won't always be successful. A quick survey of several dozen contemporary books on my shelf reveals that most don't address this episode specifically (a notable absence, in some cases ²); some tell the mutationism myth with varying degrees of panache; and a few provide a historical account rather than a myth. The few historical accounts that I found were in Gould's 2002 The Structure of Evolutionary Theory, Strickberger's 1990 textbook Evolution, and the Wikipedia entry on "Mutationism".

Sample stories

Lets look at a few examples of the mutationism story. Readers who want to check out a freely available online source from the scholarly literature may refer to Ayala and Fitch, 1997 (http://www.ncbi.nlm.nih.gov/pubmed/9223250?dopt=Citation). One example that really caught my eye is not from scientific literature, but from the 2005 obituary for Ernst Mayr in The Economist:

It was not that biologists had given up on evolution by the 1940s-quite the contrary. But they had got very confused about its mechanism. . . . The geneticists of the early 20th century did not help. They rediscovered the laws of inheritance first developed 40 years earlier by Gregor Mendel, an unsung Moravian monk. They also discovered the idea of genetic mutation. But instead of linking these things to natural selection, they came up with the idea of "saltation"-in other words, sudden mutational shifts from one well-adapted species to another. Nor, the geneticists complained, had there been enough time for natural selection to do its work, given what they had discovered about the rate at which mutations occur, and the fact that most mutations are deleterious. It was all a bit of a mess. . .Mr Mayr's advantage over the laboratory-bound biologists who had hijacked and diluted Darwin's legacy was that, like Darwin, he was a naturalist-and a good one. (anonymous, 2005)

Of course, this is a magazine article, written by anonymous staff writers-- typically one doesn't see such florid language in the scholarly literature. But did the staff writers of the Economist (representing elite opinion) really originate this story, based on their own personal recollections of the 1930's? Of course not. Mayr himself popularized the image of geneticists as laboratory-bound geeks lacking the organic insight of "naturalists". This disdain for the geneticists who "hijacked" Darwin's legacy is readily apparent when evolutionary writers depict geneticists as fools holding "beliefs" that have "obvious inadequacies", unable to understand or "grasp" their own scientific findings:

"It is hard for us to comprehend but, in the early years of this century when the phenomenon of mutation was first named, it was regarded not as a necessary part of Darwinian theory but as an alternative theory of evolution! There was a school of geneticists called the mutationists, which included such famous names as Hugo de Vries and William Bateson among the early rediscoverers of Mendel's principles of heredity, Wilhelm Johannsen the inventor of the word gene, and Thomas Hunt Morgan the father of the chromosome theory of heredity. . . Mendelian genetics was thought of, not as the central plank of Darwinism that it is today, but as antithetical to Darwinism. . . It is extremely hard for the modern mind to respond to this idea with anything but mirth" (Dawkins, 1987, p. 305)

"According to mutationism, random changes in the hereditary material are sufficient for adaptation without much, or any, selection at all. Mutations just somehow happen to be adaptive, the right changes simply manage to occur. The inadequacies of this view are obvious" (Cronin, 1991, p. 47).

"Darwin knew nothing of this [i.e., genetics] but as it turned out, his ignorance was sublimely irrelevant to the problem he was really interested in tackling: evolution. This point was not fully grasped by biologists. Many early geneticists at the dawn of the 20th century, thought their discoveries of the fundamental principles of genetics somehow cast doubt [on], or rendered obsolete, the concept of natural selection. It took several decades of experimentation and theoretical (including mathematical) analysis to show not only that there was no conflict inherent between the emerging results of genetics and the older Darwinian notion of natural selection, but that the two operate in different domains." (Eldredge, 2001, p. 67)

"Mendelian particulate inheritance (today, we call the "particles" genes) was originally identified with De Vries's "mutation theory", according to which new variations or species originated in large jumps, or macromutations, and evolution was exclusively explained by mutation pressure. Darwinian naturalists, believing that Mendelism was synonymous with mutation theory, held on to theories of soft inheritance, while they considered selection a weak force at best. They did not know of the new findings in genetics that would have supported Darwinism. (SegerstrŒle, 2002)

Notice how, in every version of the story above, the position taken by early geneticists just doesn't make sense. This isn't a story of theory versus theory, its a story of confusion ultimately yielding to reason.

If de Vries and the other geneticists are playing the role of the pied piper in this story, the "naturalists" are like the children lured away from their Darwinian home. Ultimately the innocents are returned, and order restored, by (oddly enough) mathematicians:

"Between 1918 and 1932 Fisher, Haldane, and Wright showed that Mendelian genetics is consistent with natural selection. Only then, more than 60 years after the publication of The Origin of Species, was the genetic objection to natural selection finally removed. Modern molecular and developmental genetics have confirmed in exquisite chemical detail the key aspects of genetics necessary for Darwin's ideas to work: that the genetic material is DNA, that DNA has a sequence, . . . mutates . . . contains information . . " (p. 16 of Stearns and Hoekstra, 2005)

Anatomy of a Myth

In a subsequent post, we will look at original sources to see what the "mutationists" actually believed, and why. And eventually we will integrate this into the bigger picture of how evolutionary theory developed. But for now, lets just summarize the pattern that is apparent in the literature.

First, the mutationism story is clearly a story or myth, and not an ordinary scientific truth claim. We can see this because the story-tellers are not using ordinary scientific conventions to convince us that the story is true. If you or I were making an ordinary scientific argument (for instance) for an effect of "translational selection" on codon usage, we would mention a correlation between codon frequencies and the abundance of corresponding tRNAs, citing the classic work of Ikemura (1981), and we might even repeat a figure showing this correlation, to impress this point upon the minds of readers (e.g., just as in Ch. 7 of Freeman & Herron, 1998).

When I see instances of the mutationism story, typically I don't find quotations illustrating what the mutationists believed, nor facts & figures to refute their views, but only vague attributions and generalized claims. Apropos, the following quotation from Ernst Mayr never fails to make me laugh:

The genetic work of the last four decades has refuted mutationism (saltationism) so thoroughly that it is not necessary to repeat once more all the genetic evidence against it. (Mayr, 1960)

And the puissant Dr. Mayr proceeds on, not boring the reader with any tiresome "genetic evidence", nor citing sources that might allow the reader to evaluate the truth of his statement. Its a story, after all.

By contrast, the 3 sources that I mentioned above as providing scientific history, rather than myth, all make reference to specific experimental and theoretical results, and reveal knowledge of specific historically important scientific works. For instance, Strickberger's reference list includes Johannsen, 1903, as well as the 1902 paper by Yule that reconciled Mendelian genetics with quantitative variation (in neo-Darwinian mythology, credit for Yule's work is given to little Ronny Fisher, who was 11 at the time).

Second, every story has a plot or "action", and the main action of the mutationism story is a turn of fate in which power is temporarily in the hands of the wrong people or ideas. In archetypal terms, its a story of usurpation and restoration: the throne is usurped, and the kingdom falls into darkness and confusion until the throne is restored to the king's rightful heirs. The mutationism episode didn't have to be told that way: it might have been presented as a period of reform (in which old ideas were abandoned) or discovery (when new territory was mapped out). Instead, its presented as a mistake, an interlude of confusion, a collective delusion.

Indeed, another way to look at the mythic action is that the Mendelians are wizards or false prophets who place the kingdom under a spell, leading folks astray and causing them to believe things that they just shouldn't have believed.

What delusional spell did the Mendelians cast? In the story by Eldredge, or by Stearns & Hoekstra above, the spell is that Mendelian genetics is inconsistent with "the concept of natural selection" (Eldredge). In the story told by SegerstrŒle, Cronin, Mayr and The Economist, the delusional spell is a bit different: the principle of selection is irrelevant because mutational jumps alone explain evolution.

Third, the key to restoring Darwin's kingdom was to add the missing piece of genetics. Ultimately, after the period of darkness ended, the discovery of genetics "provided the missing link in Darwin's theory" (SegerstrŒle, 2002), or "The missing link in Darwin's argument was provided by Mendelian genetics" (Ayala & Fitch, 1997). Darwinism was restored, not by taking away the power of genetics, but by redirecting it to support Darwinism. Clearly, genetics is the key to ruling the kingdom, like the One Ring that Rules them All in Tolkien's world. The ones who have the ring have the power.

The story is made more fascinating by the fact that the key to power is literally a code of rules developed by a monk that remained lost for nearly half a century. The usurpers who discover The Monk's Code misinterpret it, and use it to overthrow the true king, establishing a reign of error. But when The Founders decipher the true meaning of the Monk's Code, The Architects campaign throughout the kingdom, spreading the news: the Monk's Code proves that Darwin is the true king. Darwin's rule is re-established, all opposition ceases, and the kingdom is unified.

Homework

If you would like to contribute a mutationism story, I would be happy to start a collection if you make it easy for me by providing a complete and well formed text item. Be sure to provide a quoted passage with a source, citing exact page numbers. If we get enough stories, lets try to recruit a sociologist or historian to study this further.

Summary

To summarize, the mutationism story is a myth that is retold in secondary sources. The basic story is simple: the discoverers of genetics misinterpreted their discovery, thinking it incompatible with Darwinism; Darwinism went into disfavor; population geneticists came along and showed that genetics was the missing key to Darwinism; Darwinism was restored and once again reigned supreme.

Next time on the The Curious Disconnect, we'll start pulling on some of the loose threads of this story.

For now, note how the writers quoted above are genuinely baffled by our scientific history. It just doesn't make sense to them. A century ago, most of an entire generation of scientists thought of genetics as a contradiction of Darwinism. This is a historical fact, and presumably it has an explanation that rational folks can understand by examining what scientists of the time wrote. But this historical fact mystifies Dawkins, Eldredge, Cronin, and others.

Notes
¹ The defining characteristic of a myth is not that it isn't literally true, but that it isn't told for reason of being literally true, but for reason of being meaningful or poignant: a myth is a story with a cultural value, not necessarily a literal-truth value. The connection between myths and untruths, then, has to do with discoverability: when we find a pattern P = { X people are repeating story Y }, where X is a large number, this pattern by itself does not prove that Y is a myth because X people might have all discovered or verified Y independently; but if Y has diverse elements that are untrue (or unverifiable), then we can conclude that its repetition does not signify independent verification, suggesting that its a myth.



²The Oxford Encyclopedia of Evolution does not have an article on mutationism; the article on Morgan says nothing of his views on evolution; there is no article on Bateson; mutationism is only addressed peripherally in Hull's article on the history of evolutionary theory; it is mainly addressed in SegerstrŒle's article on neo-Darwinism.

Paul Nelson Is Confused

 
Paul Nelson is a Young Earth Creationist. He believes the Earth is less than 10,000 years old and all modern species were created separately. Nelson is also a Fellow of the Discovery Institute. Given these two facts you might wonder if anything he says is worth listening to. The answer is "yes"—lots of his writings are very (unintentionally) amusing.

Paul Nelson's latest posting on Uncommon Dissent falls into a different category. It ain't particularly funny but it does perpetuate a false impression that's very common among the IDiots, and, unfortunately, some others who should know better.

Here's what he says in Massimo Says It’s Become a Religion

What has changed within the past couple of years, however, is the rapid growth in the overtly religious (anti-religious, but that anti doesn’t really matter) content of the writings of prominent neo-Darwinian biologists, such as Jerry Coyne and Richard Dawkins. The Accomodationist Wars, which show no signs of slacking, illustrate that for many, the whole point of evolutionary theory is Getting Rid of God. A biologist who nonetheless professes his theism (Ken Miller, Simon Conway Morris, Francis Collins, et al.) — well, those people are, at best, confused. Evolution properly understood is irreligious. Not “irreligious” in the sense of indifferent or neutral. Hostile. Read the traffic at Pharyngula, Why Evolution is True, Dawkins’s site, Sandwalk, or dozens of other blogs and discussion boards. [Just to be clear: I (PN) don't think the theory of evolution is irreligious, in the sense of hostile to theism. Philosophical naturalism, however, is. But evolution and naturalism are typically conflated by their advocates.]

The accommodationist wars are about the conflict between science and religion and not "evolutionary theory" and religion. People like Paul Nelson would like to change the topic because they want to be seen as anti-evolution but not necessarily anti-science.

And it's not just "neo-Darwinians"¹ who declare that science and religion are incompatible. All kinds of scientists share this opinion. For example, there are more than a few astronomers and geologists who think the Earth is slightly more than 10,000 years old. They are firmly convinced that science is totally incompatible with Young Earth Creationism.

I guess Paul Nelson doesn't know that.

He also doesn't know that the big battle is between rationalism and superstition. In this fight atheists are trying to convince theists that their gods are delusions and they should abandon them. Some of these atheists are scientists but many are not. Don't confuse the two fights. "Science vs. religion" overlaps with "rationalism vs. superstition" but "evolution vs. creationism" is often a very separate battle. People like Ken Miller can be mostly with the good guys in "evolution vs creationism" while being on the wrong side of "rationalism vs superstition."

Paul Nelson isn't the only one who doesn't get this.
