Inside Higher Ed Weighs in on the Ball State Academic Freedom Controversy

This is getting more and more interesting. Now there's an article in Inside Higher Ed discussing the controversy over whether Eric Hedin of Ball State University should be teaching a science course that emphasizes Intelligent Design Creationism. [see Science or Religion?]

The article discusses the difference of opinion between Jerry Coyne, on the one hand, and PZ Myers and me, on the other. It's very interesting to read the comments. Jerry Coyne has posted on the Inside Higher Ed article at: Ball State agrees to investigate science course infected with Christianity. His readers have lots to say on the issue of academic freedom.

Let's be clear about one thing. I'm not an American so I'm not terribly concerned about the American Constitution. If Eric Hedin were teaching in Canada, the legal issue would never come up. The part of this that I don't like is outsiders threatening departmental chairs to get them to take action against one of their faculty members. Four Creationists have tried to get the administration of my university to shut down Sandwalk and in all cases my university simply filed the letters in the waste basket.¹ I ban people from Sandwalk if I ever hear of them trying to intimidate someone by complaining to their employer. That's unacceptable behavior in my book.

1. After sending me a copy.

Earthquake!

Epicentre near Ottawa. Two quakes: 5.2 magnitude at 9:43 am and a 4.1 magnitude aftershock 10 minutes later. I didn't feel either of them. Earthquakes like this happen about 30,000 time a year. We feel one of them every few years in this part of Canada. They are mostly harmless, but exciting.

On Teaching Genetics Using Students' and Parents' ABO Blood Types

There are some schools that think it's cool to show examples of simple Mendelian inheritance by collecting and analyzing the blood types of their students and their parents. What could possibly go wrong?

Let me tell you why this is a bad idea. It's true that 99% of the time the blood type of a student is going to be consistent with that of their presumed biological parents. But what if it's not? That could mean that a child is adopted and the child may not know or not want that information to be public. It could also mean that the child's biological father (or mother) is not the same person they call "Mommy" or "Daddy." Is the trauma associated with that discovery worth the benefits of the experiment?

I have a blog post on The Genetics of ABO Blood Types. It's quite popular and every few weeks I get a letter from a distraught parent who has just discovered that the blood type of their children doesn't match the blood type of the parents. Here's the latest example (posted with permission) ...

Dear Professor Moran: I hope you don't mind my writing to you, but I just came across your blog, Sandwalk after doing some research about blood types and wondered if you might have an opinion....

My daughter, in 7th grade is working on a blood type project at school and came home quite upset yesterday after telling the teacher that she was type A+ and both her Dad and I are O+. The teacher (whom I have not yet dragged over hot, burning coals....) told her that that was impossible - that she would either have to have been adopted or have a genetic defect.... It got me thinking that perhaps I had made a mistake somewhere along the way and we spent some time last night digging through info to try to figure it out. I checked with our doctors this morning and our daughter's pediatrician and all blood types have been confirmed. Both my husband and I are O+ and our daughter is A+ She is definitely not adopted and unless she was switched at birth, then there is no doubt as to parentage -- should I be concerned? I do recall that when she was born she had mild jaundice which one doc explained was due to blood type incompatibility.

If high school teachers aren't knowledgeable enough to handle these situations then they should avoid these "experiments."

These "anomalies" are quite frequent and they have simple explanations once you know the real genotype. For example, one parent could be heterozygous for two different O alleles. One with a mutation near the beginning of the gene and the other with a mutation near the end of the gene. Any germ cell recombination event between the two alleles could generate an A allele or a B allele depending on the origin of the O allele.

I think it's also possible for one of the parents to actually be AO or BO but the functional allele is expressed at a very low level giving an O-type phenotype. The A or B allele could, by chance, be much more active in the child. There could be epistatic effects such that splicing or transcription is defective in the parent but compensated for by enhanced activity in the child due to unlinked mutations. (These are known as "suppressors" in bacterial genetics.)

There are many other possibilities. They're rare but it's certain that they will show up in some school class somewhere. It's usually not a good idea to investigate the personal genomics of students because of these problems.

Jerry Coyne Is at it Again!

Jerry Coyne has discovered that some obscure Professor in some American college is teaching from a Christian viewpoint in his class on "The Boundaries of Science." Jerry thinks that he can stop this Professor from teaching things that he (Coyne) disagrees with by threatening the university with a lawsuit. PZ Myers and I disagreed, pointing out that academic freedom in the universities is an important principle that should not be ignored [see Is It Illegal to Teach Intelligent Design Creationism in American Universities?].

Jerry stands by his position: The Freedom from Religion Foundation to Ball State University: cease and desist your religious indoctrination. Nobody is arguing that Professors shouldn't be criticized for bad teaching and nobody is arguing that the instructor's colleagues and department can't reassign courses to keep a bad teacher away from students. That's not the situation here. The Chair of the department is aware of the situation and doesn't object.

It's dangerous for outsiders to start dictating what a Professor can and can't teach and it's especially dangerous to use legal threats to enforce your own perspective on another university. I strongly disagree with the letter that the Freedom from Religion Foundation sent to the President of Ball State University [see Coyne's blog website]. If this were my university I would expect it to fight such a demand with all the resources at their disposal and I'm certain that my union and the Canadian Association of University Teachers (CAUT) would support my university. So would I.

CAUT actively defends academic freedom as the the right to teach, learn, study and publish free of orthodoxy or threat of reprisal and discrimination. Academic freedom includes the right to criticize the university and the right to participate in its governance. Tenure provides a foundation for academic freedom by ensuring that academic staff cannot be dismissed without just cause and rigorous due process.

I have defended the academic freedom of racists and holocaust deniers in the past. I've even defended the right of an extreme free-market capitalist to indoctrinate business students. In the name of academic freedom, I will even tolerate adaptationists who teach evolution incorrectly.

The purpose of academic freedom is to protect the rights of those who disagree with the majority. Those rights must be protected for everyone, including those who you think are wrong. Otherwise it's not academic freedom.

I teach a course where I promote an atheist view of evolution and the idea that science and religion are incompatible. If the Freedom from Religion Foundation ever wrote a letter to my President demanding that I cease and desist they would be be ignored except, perhaps, for a few laughs over coffee.

Michael Denton on Junk DNA

I was reading the latest spiel from Sal Cordova (scordova) when I noticed a reference to Michael Denton. Cordova was ranting about how Taxonomic nested hierarchies don’t support Darwinism and he began with ...

Taxonomic nested hierarchies don’t support Darwinism or common descent, actually the opposite. Michael Denton convincingly argued that nested hierarchies can be used to argue against macro evolution. If the fish are always fish, then they will never be birds, reptiles, apes, or humans.

I knew that this was a misrepresentation of Denton's views since he (Denton) supports the idea that nested hierarchies represent the true history of common descent.

Michael Denton thinks that evolution was directed and that explains why fish and mammals are so different even though they contain a common ancestor. He accepts common descent but rejects spontaneous mutation and mechanistic fixation of alleles as the explanation. I checked his latest book Nature's Destiny (1998) to confirm that I was right.

Denton supports a teleological view where God created conditions (first cause) that would lead to humans (final cause) but that the process included evolution from common ancestors. In Denton's case the "design" was inherent in the laws of physics and chemistry and the rules of mutation and gene expression.

While refreshing my memory, I came across this paragraph that I had highlighted in his book fifteen years ago.

If it is true that a vast amount of the DNA in higher organisms is in fact junk, then this would indeed pose a very serious challenge to the idea of directed evolution or any teleological model of evolution. Junk DNA and directed evolution are in the end incompatible concepts. Only if the junk DNA contained information specifying for future evolutionary events, when it would not in a strict sense be junk in any case, could the finding be reconciled with a teleological model of evolution. Indeed, if it were true that the genomes of higher organisms contained vast quantities of junk, then the whole argument of this book would collapse. Teleology would be entirely discredited. On any teleological model of evolution, most, perhaps all, the DNA in a genome of higher organisms should have some function. (pp. 289-290

I wonder what Intelligent Design Creationists think of this argument?

The Positive Values of a Roman Catholic Education?

The Ontario government funds Roman Catholic Schools but not schools of any other religion. I've just returned from a high school reunion at one of the "public" schools (nonreligious) so I've been thinking about the education I received in an environment that was free of religious indoctrination.

My friends all seem to be pretty moral and they seem to be at least as good at practicing the Golden Rule as any other citizens. When we were students we organized contributions to charity and helped the needy. We made lifelong friends in the public schools.

Most of my high school friends are pretty secular in their outlook and a large percentage are nonbelievers. The percentages aren't much different among my friends who went to Roman Catholic schools.

Here's a bit of propaganda from one who supports government funding of Roman Catholic schools. They need all the support they can get because Roman Catholic values are coming under heavy criticism lately. Roman Catholic students have been bussed to anti-abortion protests and school clubs for gays and lesbians have been banned in the Roman Catholic schools system. "Sex education" is a joke.

What do you think? Does this make you want to continue sending your tax dollars to the Roman Catholic schools?

Scientific Authority and the Role of Small RNAs

A few weeks ago I criticized Philip Ball for an article he published in Nature: DNA: Nature Celebrates Ignorance. Phil has responded to my comments and he has given me permission to quote from his response. I think this is going to stimulate discussion on some very interesting topics.

The role of small RNAs is one of those topics. There are four types of RNA inside cells: tRNA, ribosomal RNA (rRNA), messenger RNA (mRNA), and a broad category that I call “small RNAs.”

The small RNAs include those required for splicing and those involved in catalyzing specific reactions. Many of them play a role in regulating genes expression. These roles have been known for at least three decades so there haven’t been any conceptual advances in the big picture for at least that long.

What’s new is an emphasis on the abundance and importance of small regulatory RNAs. Some workers believe that the human genomes contains thousands of genes for small RNAs that play an important role in regulating gene expression. That’s a main theme for those interpreting the ENCODE results. Several prominent scientists have written extensively about the importance of this “new information” on the abundance of small RNAs and how it assigns function to most of our genome.

High School Reunion

We attended the Nepean High School 90th Anniversary Celebration in Ottawa (Ontario, Canada) on the weekend. It was wonderful to see old friends, especially those I hadn't seen in almost five decades. (I graduated 49 years ago.)

Here are some friends that I have seen more recently but it was good to get together anyway. Brian (standing) is an old friend—we first met sixty years ago. Chuck (sitting) and his wife Helen (beside him) have been friends since high school. Chuck was best man at my wedding and Brian was also in the bridal party.

Two other members of my bridal party are also high schools friends. Leslie (front) was the bride and Karen (trying to hide on the left) was a bridesmaid.

Ms. Sandwalk has posted a photo of herself as a high school student and cheerleader. One of the other cheerleaders was at the reunion but nobody could convince them to do a cheer.

Almaleea subumbellata

Jerry Coyne says he will post a picture of a plant if he can find a cute one [A vertebrate]. I decided to help him out by pointing you to the latest Botany Photo of the Day.

This is Almaleea subumbellata, or wiry bushpea, from Tasmania, Australia. You can read all about it at the UBC Botanical Garden website. They have a high resolution photo.

Prettier than cats and they don't pee on your rug or scratch your furniture.

Andyjones Replies

Andyjones has responded to my post on failing to educate him about science. His response is: Failure to Educate? Failure to Persuade. I'm reposting his entire response ....

Larry Moran replied to my latest post with an admission of failure. He thinks he has failed to educate, but I think rather he is confusing the word ‘persuade’ with the word ‘educate’.

He thinks I am rationalising junk DNA with a pile of ‘what-ifs’. But the fact is that most of my ‘what-ifs’ are already known to have some basis in reality. I am not denying any obvious reality. Indeed, the basic machinery of life looks like design, far more than when Paley was around. Yes, there could also be a great deal of junk. That’s why I have said a number of times that ID is not committed to the idea that there is no junk.

Yet, from my point of view, I see a whole pile of Darwinian/post-Darwinian materialists who have only partly explored the genome, working from an assumption that the genome was not designed, and thus are jumping the gun on the evidence. For example, Larry still seems to think that pseudogenes are of themselves ‘solid evidence’ of broken genes despite the fact that we know that at least some pseudogenes influence the rate of translation of real genes by competing with them; a simple design reason why there should be ‘false genes’ = pseudogenes. Who has explored the rest of them?

From his emotive response to my perfectly valid, albeit speculative suggestions (though they were not plucked out of the air either), I don’t trust this guy to think clearly and calmly about the possibility of design. That’s the real problem.

This is all very frustrating. Why do IDiots who have no serious training in biochemistry and molecular biology think they know more than the experts?

And why do they refuse to learn when we attempt to educate them?

An Example of IDiot "Civility"

Do you remember when Stephen A. Batzer listed several reason why "Darwinists" are so uncivil? [Why Darwinism and Incivility Seem to Go Together] I blogged about it at: Why Are "Darwinists" So Uncivil?. We all had a good chuckle about hypocrisy and stupidity.

You've also seen many IDiots defend their use of "Darwinism" by claiming that it's nothing more than an accurate description of the most important scientific prerspective on evolution.

Here's what David Klinghoffer wrote today in Scientific Anti-Humanism Is Being Refuted by Science Itself.

Scientific anti-humanism refers to the cheapening of human dignity and of the value of human life in the name of science. Among many other pieces of novel information on that theme, the most important point that came out of Michael Medved's discussion with John West just now on the Science and Culture Update is that this corrosive tendency is being refuted by science itself.

Darwin persuasively taught that life is the product of blind, meaningless, purposeless churning, making all life, not just human, hardly anything more special or dignified than cosmic refuse. Indeed in a Darwinian worldview, life is cosmic refuse. While accused abortion butcher Kermit Gosnell may be an outlier, he is an emblematic personality in our Darwin-tutored culture.

How civil of him to link Darwinism with Kermit Gosnell.

Remember, this is Evolution News & Views (sic), sponsored by the Discovery Institute. This is not some backwoods hack operating on his own. It's mainstream civility for the leading Intelligent Design Creationists.

UPDATE Klinghoffer posted the following a short time later in Darwinism Versus Reality: The Painful Divorce. It's just another example of how the IDiots link "Darwinism" with immorality and it puts the lie to the claim that "Darwinism" is just another word for "evolutionary biology."

I wanted to highlight what Josh Youngkin said yesterday in his very perceptive comments about the Jodi Arias verdict. Darwinian materialists like Jerry Coyne end up asserting there's no free will, therefore no such thing as moral responsibility. A murderer may be locked up for everyone else's safety, but not because we're correct to seek to impose retribution. We have no moral right to do so.

As Josh says, this casts the human being who murders as a fundamentally blameless animal, like a man-eating tiger. We would cage or even shoot such a tiger, but we could not blame it for acting as it does.

Profoundly, I thought, Josh's article suggests how remote from human experience a guy like Coyne must travel if he wants to carry his Darwinian materialism to its seemingly logical conclusions.

Religious Affiliation in Canada

The results of the 2011 Canadian census are beginning to appear. Indi at Canadian Atheist has prepared a nifty pie chart showing that 63.7% of the population identifies themselves as Christians [2011 National Household Survey religion results].

In second place, at 23.9%, are those who say they have no religion. We know that many of the "nones" will not call themselves "atheists" but they might as well be.

The take-home lesson is that almost 24% of Canadians are not religious. That's up from 16.5% in 2001. Times they are a -changin.

The question on the census was ...

22. What is this person’s religion?

Indicate a specific denomination or religion even if this person is
not currently a practising member of that group.

For example, Roman Catholic, Ukrainian Catholic, United Church,
Anglican, Lutheran, Baptist, Greek Orthodox, Jewish, Islam, Buddhist,
Hindu, Sikh, etc.

Specify one denomination or religion only __________

No religion __________

I think you can see why nonbelievers may be somewhat higher than the numbers indicate.

On My Failure to Educate an Intelligent Design Creationist

A few weeks ago I decided to give Intelligent Design Creationist andyjones the benefit of the doubt and assumed that he really wanted to understand enough biology to have a credible opinion about genomes and junk DNA. I published a series of posts on Educating an Intelligent Design Creationist: Introduction.

Andyjones has replied to my post with: Getting me an Education.

---

My first post was: Educating an Intelligent Design Creationist: Pervasive Transcription. I refuted the misconception that nobody ever investigated pervasive transcription and I explained that we know a great deal about the parts of the genome that are being transcribed, and why they are transcribed. I did not claim that this was solid evidence for junk DNA. That wasn't the point. The point was to teach andyjones that there are explanations for pervasive transcription—we don't call it junk just because we have no idea what's going on.

I also pointed out that using pervasive transcription as an argument for function (i.e. against junk) doesn't really cut it unless you don't understand basic biochemistry. Here's how andyjones responded ...

Larry thinks this (especially the situation from the 80s on) amounts to solid evidence for junk DNA, but I honestly don’t see how it does.

Okay. So my attempt to explain the reality of the situation failed miserably.

IDiots Make a Falsifiable Prediction

The Intelligent Design Creationists, otherwise known as IDiots, are getting desperate. They have been relentlessly promoting Stephen Meyer's upcoming book Darwin's Doubt: The Explosive Origin of Animal Life and the Case for Intelligent Design but so far they have pretty much failed to trick evolutionary biologists into trashing the book before it's published.¹ That must be a major disappointment to them.

The baiting continues with an article by David Klinghoffer on the Evolution News & Views (sic) site: What Darwin's Enforcers Will Say About Darwin's Doubt: A Prediction. Here's what he predicts ....

Among possible lines of attack against Stephen Meyer's forthcoming book, Darwin's Doubt: The Explosive Origin of Animal Life and the Case for Intelligent Design, I foresee some critics trying to argue that it's not fair game for Dr. Meyer to invite the general reading public to consider what's going on in peer-reviewed technical literature pertaining to evolution.

After all, biologists should have the opportunity to air their views in a semi-private professional setting without "creationists" barging in and telling the unwashed masses that many scientists have already given up on the Darwinian paradigm and are seeking post-Darwinian alternatives. Even though it's true, still it's wrong to publicize the fact, thereby leading the common folk astray and confirming their prejudice in favor of seeing life and the universe as reflecting some purpose.

This time I will rise to the bait if only for the purpose of preserving this prediction so we can revisit it in the future.

I'd also like to note, for the record, that the IDiots have published a number of books in the past and I don't recall anyone making the argument that Klinghoffer predicts. Can anyone out there point me to an article where scientists criticized the IDiots for pulicizing controversy within the evolutionary biology literature? It would be quite hypocritical for most bloggers to do so since criticizing the scientific literature is what we do.

Is it just my imagination or have evolutionary biologists also published books where they "expose" the controversies within evolution. If scientists do it routinely then why in the world would they criticize an IDiot for doing it? That doesn't make any sense, does it? (Oops, I inadvertently made the false assumption that IDiots are supposed to be rational.)

Finally, Udo Schüklenk alerted me to this creationist article because he is mentioned. Klinghoffer refers to a discussion about the ethics of infanticide and he thinks that his creationist² buddy Wesley Smith is being attacked for exposing a debate within the bioethics community. You should read the papers he links to along with Udo Schüklenk's paper [In defence of academic freedom: bioethics journals under siege] if you want to catch up on that discussion. As usual, the IDiots get it all wrong. Are you surprised?

---

1. That's mostly because we don't care. We are not anticipating anything we haven't heard many times before although, I suppose, we could be surprised.

2. Smith is a lawyer and a Senior Fellow at the Discovery Institute. I don't know what kind of creationist he is.

Monday's Molecule #204

The last Monday's Molecule was α-linolenate [Monday's Molecule #203]. It is an omega-3 essential fatty acid. The winner was Anders Ehrnberg.

Today's molecule is actually three different molecules (1,2 and 3). Give the common names for the terminal part of each molecule—the names used in most textbooks. Identify E₂ (enzyme name) and briefly explain what's going on.

Email your answers to me at: Monday's Molecule #204. I'll hold off posting your answers for 24 hours. The first one with the correct answer wins. I will only post mostly correct answers to avoid embarrassment. The winner will be treated to a free lunch.

There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your email message.)

Atheism, Skepticism, and Canada's Centre for Inquiry

The Centre for Inquiry logo (above) is from the CFI Canada Facebook page. It's an amazing piece of work because it embodies one of the key features of CFI as an umbrella organization that brings together a number of different groups to unite around common goals.

This is a lot harder than you might think. I think of myself as a skeptic and an atheist but I am not a Humanist. If an organization like CFI were to be taken over by Humanists, I could not be a member. Other people are worried that CFI might be dominated by atheists and an atheist agenda. Some of them have left the organization because they think of themselves as skeptics who are not anti-religion.

Lately the conflict between (some) skeptics and atheists has claimed another victim. PZ Myers is so upset with the narrow view of skepticism promoted by Jamy Ian Swiss [see Skeptics have the amazing superpower of being simultaneously fierce and timid] that he now declares, "I officially divorce myself from the skeptic movement."

What's the problem? It's that some skeptic movements want to concentrate on pseduoscience and pseudomedicine and leave religion alone. They are atheists and accommodationists. Not content with just ignoring vocal atheists, they criticize their tactics as being offensive and inimical to the important skeptical causes. I don't agree with that version of skepticism and neither does PZ Myers. However, unlike PZ, I think the solution is to make it clear that people like Jamy Ian Swiss are wrong to exclude atheism from the skeptical movement.

If the skeptical movement becomes officially accommodationist and anti-atheist then I will have to abandon it just like PZ Myers did.

The advantage of CFI is that it can "accommodate" all these points of view, if we are careful. It can promote an "Extraordinary Claims" campaign that links skepticism about religion and skepticism about pseudoscience and quackery. It can launch a campaign against religion in the schools without antagonizing believers. It can promote charitable causes that bring together freethinkers, humanists, and atheists. It can sponsor Humanist officiants who can preside at weddings and funerals. It can do much to promote what all those groups have in common. All we have to do is tolerate the occasional cause that we might not completely agree with.

It's a bit ironic that PZ Myers is offended by the direction that skepticism is taking yet seems blind to the re-branding of "freethought" that he supports. I'm hoping that in Canada we can avoid the competing conferences that pit freethoughters against skeptics and atheists against humanists. So far, we seem to be on the right track with the Committee for Advancement of Scientific Skepticism (CASS) and CFI events celebrating Dawkins & Krauss and "The Unbelievers" as well as Eschaton 2012, and the upcoming Imagine No Religion.

UPDATE: Jack Scanlan of Young Australian Skeptics says, "A person can be a skeptic and believe in a god." [PZ’s Problem: Does Skepticism Makes An Exemption For Religion?]. I disagree.

Why Are "Darwinists" So Uncivil?

Let's ignore for a minute the people who comment on Sandwalk because it's clear that the most uncivil group is the creationists. Let's also ignore the people who comment on the creationist blogs because there it's also the supporters of religion who are the most uncivil. Oh hell, let's just ignore reality altogether and assume, for the sake of argument, that supporters of evolution are more uncivil than creationists.

Stephen A. Batzer speculates, very civilly, why this imaginary assumption might be true [Why Darwinism and Incivility Seem to Go Together].

1. They're human. That says a lot that's negative about them and of course about us, too.
2. They're typing, probably anonymously, on the Internet. I'm sure you have noticed the level of discourse on the Internet. The Lincoln-Douglas debates it isn't. On any topic.
3. You are challenging their religious beliefs, which they know, just know, to be true.
4. Thought leaders in the Darwinian movement, such as Dawkins, Prothero, Shermer and so on, inculcate and advocate incivility by their own example. Look at the way biologist James Shapiro and philosopher Jerry Fodor have been treated. It's ugly.
5. "A little knowledge is a dangerous thing." That Darwinism is a FACT has been proclaimed since before all of us were born. Saying that the Darwinian mechanism of speciation is not a fact strikes many folks as if you're intimating that there is no Japan. It's just a made up country. When I try to measure the level of personal knowledge that Internet advocates have of evolutionary theory, it is almost universally superficial. This includes biologists.
6. They have not taken the time to understand what the issues are or what evidence is convincing to those who disagree with them. They are ignorant in a nearly comprehensive way about why thoughtful, educated people find the "generate and filter" paradigm causally insufficient.

Isn't that amusing?

Now for the next bit ...

WARNING!!! Turn off your irony meter. It doesn't matter whether you have the updated Mark VIII with the extra power pack or not. Turn it off, NOW!!!

Here's how Stephen A. Batzer ends his post on Evolution News & Views (sic).

One thing that draws me to the ID movement is that it has the polite and understated ethic that science is supposed to have -- but does not have when the subject is evolution.

Carnival of Evolution #59

This month's Carnival of Evolution is hosted by Dirk Steinke at DNA Barcoding. He's another one of those nasty Canadian bloggers who seem to be everywhere these days. Read: Carnival of Evolution #59: A letter from the Doctor

Dear Wilfred,

Are you still watching the stars with your new telescope? I bet you can see what I see outside the windows of my TARDIS. The star you're searching for is still there, it just tends to fall out of view occasionally.

Do you remember how you always said how you'd love to be travelling with me again through the skies? I envy you right now, living on this wonderful planet in your lovely little house treating yourself to a flask of tea on your porch while you look at the stars. They're beautiful, I would know, I live amongst them and I've traveled to so many. I’ve seen galaxies born and fading away.

If you want to host a Carnival of Evolution please contact Bjørn Østman. Bjørn is always looking for someone to host the Carnival of Evolution. He would prefer someone who has not hosted before but repeat hosts are more than welcome right now! Bjørn is threatening to name YOU as host even if you don't volunteer! Contact him at the Carnival of Evolution blog. You can send articles directly to him or you can submit your articles at Carnival of Evolution although you now have to register to post a submission.

Why Politicians Shouldn't Be in Charge of Research Funding

Steven Novella blogs at Science-Based Medicine. Yesterday he was upset about American politicians who want to restrict research grants to projects that "advance the national health, prosperity, or welfare, and to secure the national defense" [Politics of Public Research Funding]. The goal is to put a stop to silly basic science research like studying sex in snails.

Here's the quote of the day from Steven Novella.

I have noticed, however, that researchers have become reflexively good at making up plausible-sounding possible applications for their basic science research – as if they have to constantly justify their research. Every basic-science study that looks at viruses, therefore, may one day cure the common cold. Anything dealing with cell replication may be a cure for cancer. Any materials advance will lead to supercomputers or superlight vehicles. All brain research, apparently, might one day cure Alzheimer’s disease.

I would love for a scientist to say something to the effect of “I have no idea what, if any, practical use this research might lead to, but the knowledge is really cool”. I guess you just don’t say that to a grant committee, however.

The Molecular Evolution Exam

The students in my Molecular Evolution course have written the final exam. I finished grading the exams yesterday and the final course marks have been submitted. Now I don't have to think about teaching until August.

Just for fun, I'm posting the final exam questions. How do you think you'd do? I gave the students a list of all possible questions on the last day of class. The only one they hadn't seen was question #2. They knew that the first question would definitely be on the exam.

Students had to answer questions 1 & 2 and choose any three of the other questions.

1. Choose a subtopic from your essay and explain it better than you did in your essay and/or rebut the comments and criticisms made by the marker/grader.
2. Imagine that identical female twins were born to a woman in 1000 AD. Imagine that you could find a direct descendant of each twin in 2013. If you sequence the complete genomes of the descendants, approximately how many differences would you expect to find? How do these compare to the differences between any two randomly selected individuals from the same part of the world? Explain your reasoning and describe any assumptions you make. Think carefully before you answer. The second question is the most important one. (Human mutation rate = 130 mutations per generation. Haploid genome size = 3.2 × 10⁹ bp.)
3. There are hardly any pseudogenes in bacterial genomes. Why haven’t pseudogenes been eliminated from our genome?
4. Explain the two-fold cost of sex. Why is this a problem in evolutionary theory?
5. Richard Lenski’s group at Michigan State University has been following the evolution of 12 cultures of E. coli for over 50,000 generations. All 12 cultures are grown under exactly the same experimental conditions and the mutation rate is high enough that every culture has been exposed to multiple mutations at every base pair in the genome. Explain why only one of the cultures has evolved the ability to use citrate as a carbon source.
6. Why is the Three Domain Hypothesis being challenged by some molecular evolutionary biologists? What are the alternatives?
7. What do you think of Kirschner and Gerhart’s “Theory of Facilitated Variation.” Is this something that has to be incorporated into a new extended version of evolutionary theory? What, if any, are the limitations of the theory and what, if any, new insights into evolution does it provide?

Richard Dawkins Is a Scholar and a Gentleman

Most of you think of Richard Dawkins as a "strident atheist" who doesn't suffer fools gladly.¹ The first part of that reputation ("strident atheist") is unjust as Dawkins pointed out on several occasions when he was in Toronto earlier this week.

The second part ("doesn't suffer fools gladly") is quite true. Dawkins thinks that foolish things, like religion and other superstitions, deserve to be ridiculed.

Richard Dawkins and I agree on atheism but disagree on some aspects of evolution. I'm pleased to report that he didn't hold that against me when we met for brunch a few days ago. I guess that means I'm not a fool in his mind!

For those of you who have never had the pleasure of meeting him, I want to assure you that in person he is a very pleasant fellow and lives up to the very British expression, "a scholar and a gentleman."

Some of the people I met were wondering about the reasons why I disagree with some aspects of Richard's views on evolution. They haven't heard of Stephen Jay Gould and I find that very sad. I still believe that everyone interested in evolution has to read and understand the "Spandrels" paper.

Here's a short reading list ....

Monday's Molecule #203

The last Monday's Molecule was medium chain acyl-CoA dehydrogenase (MCAD) (PDB 2AIT). Nobody got the right answer [Monday's Molecule #202].

Today's molecule is very important for humans. You need to supply the common name AND a more official IUPAC name that identifies the configuration of the bonds. You also need to briefly explain why this molecule is important in humans.

Email your answers to me at: Monday's Molecule #202. I'll hold off posting your answers for 24 hours. The first one with the correct answer wins. I will only post mostly correct answers to avoid embarrassment. The winner will be treated to a free lunch.

There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your email message.)

Dawkins and Krauss on CNN

Here's a CNN interview with Richard Dawkins and Lawrence Krauss. It was recorded this morning. It's very unfortunate that the reporter (Poppy Harlow) injects her own views on religion but at least they serve to illustrate the prejudice against unbelievers.

There are quite a few CNN reporters who broadcast their Christian views at every opportunity. They just don't get it.

DNA: Nature Celebrates Ignorance

Some freelance science writer named Philip Ball has published an article in the April 25, 2013 issue of Nature: Celebrate the Unknowns.

The main premise of the article is revealed in the short blurb under the title: "On the 60th anniversary of the double helix, we should admit that we don't fully understand how evolution works at the molecular level, suggests Philip Ball."

What nonsense! We understand a great deal about how evolution works at the molecular level. Perhaps Philip Ball meant to say that we don't understand the historical details of how a particular genome evolved, but even that's misleading.

I've commented before on articles written by Philip Ball. In the past, he appeared to be in competition with Elizabeth Pennisi of Science for some kind of award for misunderstanding the human genome.

Keith Yamamoto on Taking Risks

Here (below) is my old friend, Keith Yamamoto, talking about taking risks in science. Keith and I were graduate students in Bruce Alberts' lab over 40 years ago. That's him on the left in the photo. I'm the one looking up and the third former graduate student is Glenn Herrick.

Keith and I learned a lot about science from our former mentor. I learned a lot from Keith; for example, he taught me that it is more important to print in your notebook than to use cursive writing. I've been printing ever since.

Keith also helped me learn that it's sometimes important to fight for a cause even if you know you're going to lose. (He was county coordinator for the George McGovern presidential campaign in 1972.¹)

The take-home message in this video is that good scientists need to take risks. It's one of those "motherhood" kinds of statements that every scientist will support but few actually do it. It saddens me to say that today we live in a culture where mundane, data-collecting, science is often more successful than risky science (e.g. ENCODE). Risk entails the possibility of failure and even though you might learn from failure [Bruce Alberts on Learning from Failure], it won't do you much good if you don't get a job or you lose your grant.

So I disagree with Keith when he says that we should encourage risk-taking in young scientists. Some of the best scientists I know took risks and and the work didn't pan out. They couldn't get any papers published and they lost their grants. They were cut out of the system in favor of scientists who could guarantee successful results in their grant proposals. The fact that the results were boring and did nothing to advance our knowledge, wasn't important.

I advise young scientists, post-docs, and graduate students to always have a "safe" project. Don't put all your eggs in the risky science basket. It makes me sad to give that advice.

Bruce Alberts on Learning from Failure

Here's a short talk from my thesis supervisor on learning from failure. He tells the story of how he failed his Ph.D. oral and how he almost gave up writing his textbook.

I was a gradate student in his Princeton lab from 1969-1974. The most important lesson I learned from Bruce was the importance of knowledge and context. He taught a graduate course called "Macromolecules" where he explained both the basic chemistry and the basic biology. The lesson was clear. You can't do good science unless you see the big picture and understand the fundamentals of your discipline. He reminded us almost every day. As he says in the video ...

Theoretical biology is much more important than my generation had imagined. We were misled by the striking success of the 1953 Watson-Crick DNA model.

I also agree with another comment he makes in the video ...

Both book writing and teaching are really important for creative science, I believe.

Bruce also encouraged us to explore topics outside of our research project. This included Jacques Monod's book "Chance and Necessity: Essay on the Natural Philosophy of Modern Biology" and the writings of the best theoretical biologists of the time. We were encouraged to get involved in politics and society. It was a time of protest and revolution, and scientists had a role to play.

PZ's Wonderful Exam Question

PZ Myers has just given his students a take-home exam. Here's one of the questions [It’s another exam day! ] ...

Question 1: One of Sarah Palin’s notorious gaffes was her dismissal of “fruit fly research” — she thought it was absurd that the government actually funded science on flies. How would you explain to a congressman that basic research is important? I’m going to put two constraints on your answer: 1) It has to be comprehensible to Michele Bachmann, and 2) don’t take the shortcut of promising that which you may not deliver. That is, no “maybe it will cure cancer!” claims, but focus instead on why we should appreciate deeper knowledge of biology.

That first restriction is going to make answering the question a real challenge 'cause you have to take into account the mentality of someone who is not just scientifically illiterate but scientifically anti-literate.

Nevertheless, this is exactly the sort of thing you want your science graduates to know.

Is It Illegal to Teach Intelligent Design Creationism in American Universities?

Jerry Coyne has discovered that a course at Ball State University (Indiana) teaches science from a viewpoint that's sympathetic to Intelligent Design Creationism [“Science” course at Ball State University sneaks in religion]. It looks like a really bad course and I'm glad that it's getting a lot of negative publicity. It looks like the instructor is advocating Intelligent Design Creationism.

I defend the right of a tenured professor to teach whatever he/she believes to be true no matter how stupid it seems to the rest of us.¹ I'm troubled by the fact that some people are calling for the instructor's dismissal and writing letters to the chair of his department. We really don't want to go down that path, do we? Academic freedom is important and it's especially important to defend it when a professor is pushing a view that we disagree with.

But that's not the only troubling thing about Jerry Coyne's post and the comments it has stimulated. Jerry thinks that it is unconstitutional (i.e. illegal) for a university professor to be advocating religion in a publicly-funded university. He says,

Ball State University, in Muncie, Indiana, is a public university (i.e., part of the state university system). As such, it must abide by the First Amendment to the U.S. Constitution, which has been interpreted as disallowing religious viewpoints (or religiously based theories) in public-school science classes. It is of course kosher to teach courses on the history of religion, or on the relationship between science and religion, but those must not pretend to be “science” courses, and must present balanced views—they can’t push a particular religious viewpoint.

But it’s come to my attention that a science course at Ball State University—actually two courses, because it seems to be cross-listed—is little more than a course in accommodationism and Christian religion, with very little science. It’s my firm opinion that teaching this course at a state university not only violates the First Amendment, but cheats the students by subjecting them to religious proselytizing when they’re trying to learn science.

Is he right? Does the US Constitution really specify that you can't advocate a religious viewpoint in a university classroom?

That's very scary. It probably means that you can't criticize religion either. Does this mean that there's going to be a bevy of lawyers on both sides of the issue examining the content of university courses all across America?

UPDATE:
PZ Myers: I have to disagree with Jerry Coyne

Sixty Years Ago Today: April 25, 1953

Sixty years ago on this day, Nature published three back-to-back papers on the structure of DNA. It was a momentous day for science. Here's how Horace Judson describes it in The Eighth Day of Creations (pp. 154-155)...

The letter to Nature appeared in the April 25 issue. [It was submitted on April 2—LAM] To those of its readers who were close to the questions, and who had not already heard the news, the letter must come off like a string of depth charges in a column sea. "We wish to suggest a structure for the salt of deoxyribose nucleic acid (D.N.A.). This structure has novel features which are of considerable biological interest," the letter began; at the end, "It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material." That last sentence has been called one of the most coy statements in the literature of science. According to Watson, Crick wrote it. Wilkins's paper followed, signed also by two of his associates at King's College, A. R. Stokes and H. R. Wilson. It was a restatement of helical diffraction theory, and sprang to life and significance only in the last paragraphs, where Wilkins briefly reported that his x-ray diffraction studies of intact sperm heads and bacteriophage—both, of course, containing a high proportion of DNA—gave patterns that suggested that DNA in living creatures has a helical structure similar to the model just proposed. The note by Franklin and Gosling came next. It was a revision and extension of their draft from the middle of March, in the light of the model. It presented the crucial diffraction photo structure B and analyze that and the other experimental evidence to show—with curt authority—that Franklin's data were compatible with Watson and Crick's structure.

The three papers are ....

Watson, J.D. and Crick, F.H.C. (1953)A Structure for Deoxyribose Nucleic Acid. Nature 171:737-738. [See: The Watson & Crick Nature Paper (1953)] [PDF]

"We wish to suggest a structure for the salt of deoxyribose nucleic acid (D.N.A.). This structure has novel features which are of considerable biological interest."

Wilins, M.H.F., Stokes, A.R., and Wilson, H.R. (1953) Molecular Structure of Deoxypentose Nucleic Acids. Nature 171:738-740. [See: The Wilkins, Stokes and Wilson Nature paper (1953)] [PDF]

"The biological significance of a two-chain nucleic acid unit has been noted (see preceding communication). The evidence that the helical structure discussed above does, in fact, exist in intact biological systems is briefly as follows: ..."

Franklin, R. and Gosling, R.G. (1953) Molecular Configuration in Sodium Thymonucleate. Nature 171:740-741. [See: The Franklin & Gosling Nature paper (1953)] [PDF]

"Thus, while we do not attempt to offer a complete interpretation of the fibre-diagram of structure B, we may state the following conclusions. The structure is probably helical. The phosphate groups lie on the outside of the structural unit, on a helix of diameter about 20 Å. The structural unit probably consists of two co-axial molecules which are not equally spaced along the fiber axis, their mutual displacement being such as to account for the variation of observed intensities of the innermost maxima on the layer lines; if one molecule is displaced from the other by about three-eights of the fibre-axis period, this would account for the absence of the fourth layer line maxima and the weakness of the sixth. Thus, our general ideas are not inconsistent with the model proposed by Watson and crick in the preceding communication."

Nothing in Biochemistry Makes Sense Except in the Light of Evolution

The title of this post is a slight paraphrasing of Theodosius Dobzhansky's famous saying, "Nothing in Biology Makes Sense Except in the Light of Evolution. That was the title of an article he published in American Biology Teacher and that's significant since the main point was to convince teachers that evolution is important.

What applies to biology also applies to biochemistry. Evolution should come up in many places in a typical biochemistry course. The most obvious place is when we teach comparisons of nucleotide and amino acids sequences and the construction of phylogenetic trees. Students have to know the underling concept behind these comparisons. The have to know why some sequences are conserved (negative selection) and why some sequences are variable (fixation of neutral alleles by random genetic drift).

But this isn't the only place where evolution is important. How can you explain why humans need vitamin C and "essential" amino acids without mentioning evolution? How can you teach biochemistry without covering the evolution of biochemical pathways? How do you explain the existence of a complex process like the membrane-bound photosynthesis complexes in chloroplasts without showing how it evolved from simple bacterial examples? Who teaches the information flow section of the course without starting with E. coli and working toward the more complex eukaryotic examples? How do you explain why animals need glucose when most species don't need an external supply of complex carbohydrate? How do you explain why gluconeogenesis is a more primitive pathway than glycolysis? Why are comparative genome studies important in working out metabolic networks? Why does "homology modeling" work?

The American Society for Biochemistry and Molecular Biology (ASBMB) is trying to set up a certification scheme for biochemistry programs in America. The idea is that universities and colleges that meet certain standards would receive a stamp of approval from ASBMB. There would be a nation-wide exam for graduating students and if they pass the exam they get a sort of "certification" that proves they have the minimum skills and knowledge to take jobs that require these skills.

The trick is to define the common skills and knowledge that are needed. I attended two sessions at EB2013 where these criteria were discussed. One was a presentation by the committee in charge followed by some discussion: "ASBMS Certification Program for Bachelor's Degrees in Biochemistry Molecular Biology and Related Majors." The questions in this session were focused on how to get certified and not on what was in the proposal.

The other session was "Promoting Concepts-Driven Teaching Strategies in BMB Through Concept Assessments" but, as it turned out, there was very little chance to discuss the concepts that were being assessed.

You can read the current draft proposal by clicking on the link at ASBMB Degree Certification Program in Biochemistry and Molecular Biology. You might be interested in finding out what a department needs to do in order to be certified.

I'm more interested in what biochemists have to teach. Here's the relevant section ...

Core Concepts and Learning Objectives

An ASBMB-recognized program should be able to relate each element of its BMB curriculum to one or more of the core concepts listed below and their related learning objectives (For reasons of space, sample learning objectives are provided in Appendices II – V):

1. Energy is Required by and Transformed in Biological Systems.
2. Macromolecular Structure Determines Function and Regulation
3. Information Storage and Flow Are Dynamic and Interactive.
4. Discovery Requires Objective Measurement, Quantitative Analysis, & Clear Communication.

The curriculum should present these core concepts in a manner that illustrates the pervasive role that Evolution plays in shaping the form and function of all biological molecules and organisms.

That last sentence is new to me. I've never seen it on any of the slides shown at either of the meetings I attended (EB2012 and EB2013).

It's a welcome addition. But, since most biochemistry courses in America are taught out of Chemistry Departments, I wonder if this will make certification more difficult.

Finally, I can't help but insert a plug for my book. It's the only biochemistry textbook that presents the subject from an evolutionary perspective and it's certainly the only textbook where the pervasive role of evolution is emphasized in every chapter.

The next step will be to help the organizing committee refine and upgrade the "Learning Objectives" for each of the core concepts. These are given in four appendices in the draft document.

Measuring Teaching Effectiveness

Having just sat through many talks and read many posters on how to measure what we teach, I'm struck by the overwhelming emphasis on how to measure what biochemists are teaching and the incredible lack of interest in evaluating whether we are teaching the right things.

That's why this image resonated with me. Arthur L. Costa is a retired Professor of Education at the California State University, Sacramento.

Better Biochemistry at EB2013

I've been talking to a lot of people here at EB2013 in Boston. One of the main topics of conversation is education in biochemistry and molecular biology. Another is blogs and social media. Some of these new friends are going to be looking at Sandwalk so I've prepared a short list of links on teaching biochemistry.
