Is the World Flat?

 
Sherri Shepherd doesn't believe in evolution. She's not sure whether the world is flat or not. After watching this clip of The View you have to wonder about the intelligence of people on television. This really is flabbergasting. If I didn't know any better, I'd say it was all an act. Nobody could possibly be that stupid.

Catholic Bishops Block HPV Vaccinations

 
The Ontario government will provide free access to Gardasil®, a vaccine aginst Human Papillomavirus (HPV), for all Grade 8 girls in the province. The vaccine protects against 70% of all cervical cancers. HPV is acquired through sexual activity.

The vaccine will be administered in the public schools in three separate injections spread out over 6 months. The normal cost of the vaccine is $400. Once the series of shots is complete, women will be immune to the virus for many years.

See update
below.
The program is proceeding in the public schools but some Roman Catholic schools are threatening to block the vaccination of their young female students [Catholic schools debating moral issue of HPV shot]. The opposition in the Catholic schools is being stimulated by a letter from the Roman Catholic Bishops who oppose the vaccination program on the grounds that adolescent teenage girls should not be having sex in the first place.

Let's look at the letter sent to district school boards from the Ontario Council of Catholic Bishops [A message to Directors of Education of Catholic School Boards and to the Catholic educational community].

In August 2007, the Government of Ontario announced the introduction of the Human Papilloma Virus (HPV) vaccine into the publicly funded immunization program. This means that female students in all grade 8 classrooms in our school system will be offered the vaccine over the course of this year. This is a voluntary program and parents have the final decision on whether their daughters will be vaccinated.

The Bishops affirm that parents have the right and responsibility to decide whether their daughters should be vaccinated. We encourage parents to keep in mind some important considerations.

First, infection with HPV or other sexually transmitted diseases can occur only through sexual activity, which carries with it profound risks to a young person's spiritual, emotional, moral, and physical health. The Bishops note that, at best, a vaccine can only be potentially effective against one of these risks, that to physical health, and may have other unintended and unwanted consequences. Sexuality is a great and powerful gift. Sexual activity is appropriate only within marriage. Outside of marriage, abstinence is not only clearly the choice that leads to spiritual and moral wellbeing, but it is obviously the best protection against risks of disease.

Now, abstinence may be the choice that the Bishops have made but it's not a choice that's going to appeal to most teenagers. The Bishops can't really be this stupid, can they? Do they really think that most of their students are going to refrain from all sexual activity until they get married? What planet are they living on?

Second, there is no consensus among those involved in public health in Canada that HPV vaccination is the most prudent strategy in terms of allocating health care resources to address the goal of preventing deaths resulting from cervical cancer.

As we discussed in class today, when confronted with powerful scientific evidence—in this case that the vaccine prevents cancer—the goal is to discredit the data in any way possible. Here the Bishops are raising the issue of better cures. The implication is that parents should not support the HPV vaccination program because the the government could possibly have developed a "more prudent" strategy. Do the Bishops know of a better way to prevent cervical cancer? If so, why aren't they telling us?

The argument is bogus for two reasons. First, the real reason for opposition is that the vaccine may encourage promiscuity. Anything else is a red herring. Second, the program is under way and it's known to work. Refusing to protect our children from a known cancer using a known available treatment on the ground that there may have been something better is—how shall we say—really stupid.

Note the use of the "controversy" tactic. By bringing up the point that there may not be a consensus among public health officials, you cast doubt on the validity of the program. This gives you an excuse to criticize it without having to look like a prude who's completely out of touch with reality.

Further research is required. The Bishops of Ontario encourage parents to learn the medical facts concerning this vaccination.

This is classic spin framing. Make it sound like there's a real scientific problem here even if there isn't. What's the harm in waiting? Well, I'll tell you what's the harm. Cervical cancer.

Although the HPV vaccination program properly leaves the choice of participation to parents, the Bishops of Ontario regret its introduction without further opportunity for thorough study of all of the effects of this program. The best interests of children demands that parents and guardians be fully informed before granting consent.

The Bishops don't want to vaccinate young girls because those young girls shouldn't behaving sex. Everything else is obfuscation. You can tell it's obfuscation because this debate is not going on in the public schools were the vaccination is underway. If there really was legitimate concern about the safety of the vaccine then surely it would be debated in the public schools.

Parents and educators want to prepare children well for their future in all aspects of their lives. A proper education in chastity helps young people to embrace their sexuality with confidence and joy. We ask that Catholic school boards include this message in the information package that parents receive
concerning the program.

That's better. The real reason the Bishops are against protecting their young women against cancer is because chastity helps them embrace their sexuality. (There's a pun in there somewhere but I'm not going to touch it.)

Yours in Christ
Most Reverend James Wingle,
Bishop of St. Catharines
President
Ontario Conference of Catholic Bishops

Nobel Laureate: Thomas Hunt Morgan

 

The Nobel Prize in Physiology or Medicine 1933.

"for his discoveries concerning the role played by the chromosome in heredity"

Thomas Hunt Morgan (1866-1945) received the Nobel Prize in Physiology or Medicine for his work on the genetics of the fruit fly Drosohila melanogaster. Morgan is responsible for elucidating the basic mechanims of inheritance—especially sex-linked genes. His lab constructed the first genetic maps of chromosomes.

Morgan's influence was enormous. During the middle part of his career he ran a fly lab at Columbia University where he attracted people like Alfred Sturtevant, Calvin Bridges and H.J. Muller. Later on when the Morgan lab moved to CalTech he became head of the Biology Division and hired some notable scientists like; George Beadle, Boris Ephrussi, Edward L. Tatum, Linus Pauling and Sidney W. Fox. Morgan is known and respected as much for his influence on others as for his own work in the lab [see Thomas Hunt Morgan and His Legacy by E.B. Lewis].

Morgan was not able to be present at the award ceremony in Sweden because of administrative duties at CalTech where he was setting up the Biology Division. The presentation speech was delivered by F. Henschen of the Royal Caroline Institute, on December 10, 1933.

Your Majesty, Your Royal Highnesses, Honourable Audience.

As long as human beings have existed they will have observed children's resemblance to their parents, the resemblance or non-resemblance of brothers and sisters, and the appearance of characteristic qualities in certain families and races. They will also early have asked for an explanation of these circumstances, which has produced a kind of primitive theory of heredity chiefly on a speculative basis. This has been characteristic of the theories of heredity right up to our time, and as long as there existed no scientific analysis of the hereditary conditions, the mechanism of fertilization remained impenetrable mysticism.

Old Greek medicine and science took much interest in these questions. In Hippocrates, the father of the healing art, you can find a theory of heredity that probably can be traced back to primitive ideas. According to Hippocrates, inherited qualities, in some way or other, must have been transmitted to the new individual from different parts of the organisms of the father and the mother. Similar ideas of the transmission of qualities from parents to children are to be found in other Greek scientists, and, modified, also in Aristotle, the greatest biologist of the olden times.

Later on, this so-called transmission theory has been dominating. The only theory of heredity that has perhaps rivalled it, is the so-called preformation theory, an old scholastic idea that can be followed back to Augustine, the father of the Church. This theory maintained that, by the creation of the first woman, all following generations were also preformed in this first mother of ours. In modified form the preformation theory dominated the biology of the eighteenth century. Nevertheless, the transmission theory survived. Its last great representative was Darwin. He also seems to have understood heredity as a transmission of the personal qualities of the parents to the offspring through a kind of extract from the different organs of the body.

This conception, however, that is thus deeply rooted in the biology of past times and that will still be adopted rather generally, is fundamentally false; it has been reserved to the genetic researches of our time to prove this.

Modern hereditary researches are of a recent date, they are not yet seventy years old. Their founder is the Augustine monk Gregor Mendel, Professor at Brünn, who published (1866) his experiments on hybridization among plants, fundamental for this whole science. In the same year, in Kentucky, the man was born, who became Mendel's heir and founder of the school in heredity researches that has been called higher Mendelism, the winner of this year's Nobel Prize in Physiology or Medicine, Thomas Hunt Morgan.

Mendel's observations are of revolutionizing importance. As a matter of fact they completely upset the older theories of heredity, although this was not at all appreciated by his contemporaries. Mendel's discoveries usually are stated in two heredity laws or better rules of heredity. The first of his rules, the cleaving rule, means that if two different hereditary dispositions or hereditary factors (genes) for a certain quality - for instance for size - are combined in one generation, they separate in the following generation. If, for instance, a constantly tall race is crossed with a constantly short race, the individuals of next generation become altogether medium-sized, or, if the factor «tall» is dominant, exclusively tall. In the following generation, however, a cleaving takes place, so that once more the size of the individuals becomes variable according to certain numerical proportions, then of four descendants: one tall, two medium-sized, and one short.

The second of Mendel's rules, the rule of free combinations, means that, when new generations arise, the different hereditary factors can form new combinations independent of each other. If, for instance, a tall, red-flowered plant is crossed with a short, white-flowered one, the factors red and white can be inherited independent of the factors large and small. The second generation then, besides tall red-flowered and short white-flowered plants, produces short red-flowered and tall white-flowered ones.

Mendel's immortal merit is his exact registration of the special qualities and consequent following of their appearance from generation to generation. In this way he discovered the relatively simple, recurrent, numerical proportions, which give us the key to a true understanding of the course of heredity. The experimental genetics of our century then has proved that, taken as a whole, these Mendel rules are applicable to all many-celled organisms, to mosses and flowering plants, to insects, mollusks, crabs, amphibia, birds, and mammals.

Mendel's rules, however, met with the same fate as many other great discoveries that have been made before their time. Their significance was not understood, they fell into oblivion, and after pater Mendel had died in 1884, nobody mentioned them any more. Darwin apparently knew nothing about his great contemporary; otherwise he could have made use of Mendel's works for his own researches, and the rediscovery of Mendel's work was made only about 1900.

By that time, however, the qualifications for the application and perfection of Mendel's theories were quite different from those of their first publication. The general biological attitude had changed, and, above all, the knowledge of the cell and the cell nucleus had made excellent progress. The mechanism of fertilization had been discovered by Hertwig in 1875, and in the eighteen-eighties Weismann had asserted the opinion that the nuclei of the sex cells must be the bearers of the hereditary qualities. The indirect or mitotic cell division and the chromosomes - the strange, threadlike, colourable structures that then appear - had been discovered by Schneider in 1873 already. Only several decades later, however, was the meaning of the remarkable cleaving, wandering, and fusion of these chromosomes during the different phases of the cell division and the fertilization understood.

When, at last, Mendel's discoveries came to light, their significance was soon perceived. Behind Mendel's rules there must be some relatively simple, cellular mechanism for the exact distribution of the hereditary factors at the genesis of the new individual. This mechanism was found just in the proportion of chromosomes in the sex cells before and after the fertilization. The opinion that the chromosomes are the real bearers of heredity was first clearly pronounced by Sutton in 1903, and by Boveri in 1904. This opinion was enthusiastically received by the students of the cell. Only by this discovery organic life got the unity, the continuity that human thought demands and that is more real and more provable than the hypothetic common descent of Darwinism.

The further development of the chromosome theory during the first decade of this century may here be skipped. However, the soil was well prepared when, in 1910, the American zoologist Thomas Hunt Morgan began his researches in heredity. These soon led him to the great discoveries regarding the functions of the chromosomes as the bearers of heredity that have now been rewarded with the Nobel Prize for Medicine in 1933.

Morgan's greatness and the explanation of his astonishing success is partly to be found in the fact that, from the beginning, he has understood to join two important methods in hereditary research, the statistic-genetic method adopted by Mendel, and the microscopic method, and that he has always looked for an answer to the question: which microscopic processes in cells and chromosomes result in the phenomenons appearing at the crossings?

Another cause for Morgan's success is no doubt to be found in the ingenious choice of object for his experiments. From the beginning Morgan chose the so-called banana-fly, Drosophila melanogaster, which has proved superior to all other genetic objects known so far. This animal can easily be kept alive in laboratories, it can well endure the experiments that must be made. It propagates all the year round without intervals. Thus a new generation can be had about every twelfth day or at least 30 generations a year. The female lays about 1,000 eggs, males and females can easily be distinguished from each other, and the number of chromosomes in this animal is only four. This fortunate choice made it possible to Morgan to overtake other prominent genetical scientists, who had begun earlier but employed plants or less suitable animals as experimental objects.

Finally, few have like Morgan had the power of assembling around them a staff of very prominent pupils and co-operators, who have carried out his ideas with enthusiasm. This explains to a large extent the extraordinarily rapid development of his theories. His pupils Sturtevant, Muller, Bridges, and many others stand beside him with honour and have a substantial share in his success. With perfect justice we speak about the Morgan school, and it is often difficult to distinguish what is Morgan's work and what is that of his associates. But nobody has doubted that Morgan is the ingenious leader.

As Mendelism can be summed up in Mendel's two rules, Morganism, at least to a certain extent, can be expressed in laws or rules. The Morgan school usually speaks of four rules, the combination rule, the rule of the limited number of the combination groups, the crossing-over rule, and the rule of the linear arrangement of the genes in the chromosomes. These rules complete the Mendel rules in an extraordinarily important way. They are all inextricably connected, and form together a close biological unity.

It is true that Morgan's combination rule, according to which certain hereditary dispositions are more or less firmly combined, limits to a large degree Mendel's second rule that, at the formation of new hereditary substances, the genes may be freely combined. It is completed by the rule of the limited number of the combination groups, which has turned out to be corresponding to the number of chromosomes. On the other hand, the combination rule is confined by the strange phenomenon that Morgan calls crossing-over or the exchange of genes, which he imagines as a real exchange of parts between the chromosomes. This crossing-over theory has met with much resistance. During the last few years, however, it has got a firm support through direct microscopic observations. Also the theory of the linear arrangement of the hereditary factors seemed in the beginning a fantastic speculation, and the publication of Morgan's so-called genetic chromosome map, upon which the different hereditary factors are checked in the chromosomes like beads in a necklace, was greeted with justified scepticism. The fact was that Morgan had arrived at these sensational conclusions by statistic analysis of his Drosophila crossings and not by direct examination of the chromosomes, which, besides, is possible only in exceptional cases. But also on this point later researches have acknowledged him to be in the right, and nowadays also other genetic scientists admit that the theory of the localization of the hereditary factors within the chromosomes is not an abstract way of thinking but corresponds to a stereometric reality.

The results of the Morgan school are daring, even fantastic, they are of a greatness that puts most other biological discoveries into the shade. Who could dream some ten years ago that science would be able to penetrate the problems of heredity in that way, and find the mechanism that lies behind the crossing results of plants and animals; that it would be possible to localize in these chromosomes, which are so small that they must be measured by the millesimal millimetre, hundreds of hereditary factors, which we must imagine as corresponding to infinitesimal corpuscular elements. And this localization Morgan had found in a statistic way! A German scientist has appropriately compared this to the astronomical calculation of celestial bodies still unseen but later on found by the tube - but he adds: Morgan's predictions exceed this by far, because they mean something principally new, something that has not been observed before.

Morgan's researches chiefly occupy themselves with the family of Drosophila, and perhaps it may seem strange that his discoveries have been rewarded with the Nobel Prize for Medicine, which is to be bestowed on the man who «has done the greatest service to mankind» and «has made the most important discoveries in the field of physiology or medicine». To this may first be alleged that numerous later examinations of other genetic objects, of lower and higher plants and animals, have given evidence of the fact that, as a principle, Morgan's rules are applicable to all many-celled organisms.

Further, comparative biological research has for a long time shown a far-extending fundamental correspondence between man and other beings. We can therefore consider it as a matter of course that also such an elementary function of the cell as the transmission of hereditary dispositions is similar, that, in other words, Nature uses the same mechanism with man as with other beings to preserve species, and that Mendel's and Morgan's rules thus are applicable also to man.

Human hereditary researches have already made great use of Morgan's investigations. Without them modern human genetics and also human eugenics would be impractical - it may be that eugenics still chiefly remain a future goal. Mendel's and Morgan's discoveries are simply fundamental and decisive for the investigation and understanding of the hereditary diseases of man. And considering the present attitude of medicine and the dominating place of the constitutional researches, the role of the inner, hereditary factors as to health and disease appears in a still clearer light. For the general understanding of maladies, for prophylactic medicine, and for the treatment of diseases, hereditary research thus gains still greater importance.

Mr. Steinhardt. The Caroline Institute regrets very much that Professor Morgan is not able to be here today in person. I beg Your Excellency, as the official representative of the United States of America, to accept the Nobel Prize for Professor Morgan. May I also ask Your Excellency, in forwarding the prize to him, to convey with it the admiring congratulations of our Institute.

Eye Color in Fruit Flies

 
Monday's Molecule #43 is drosopterin, a major pigment in the eyes of the fruit fly, Drosophila melanogaster.

The biochemical pathway shown below is an updated figure similar to one taken from an undergraduate lab manual where students identify the pigments by thin layer chromatography [Thin Layer Chromatography of Eye Pigments of Drosophila melanogaster].

There are two kinds of pigments required for the normal red eyes. The ommochrome pathway produces a brown pigment and the drosopterin pathway produces a bright red (scarlet) pigment. Both pigments are transported to the site of eye formation by a common transport system.

The precursor of ommochrome is the amino acid tryptophan and the initial precursor in the drospterin pathway is the nucleoside guanine. Guanine and tryptophan need to be transported into the site of synthesis by specific membrane transporters.

Mutations in the transport system block the transport of the pigments and result in flies with white eyes (left) and various other colors such as brown and scarlet.




One of the proteins in the both the guanine and tryptophan transport system is the product of the white gene. Mutations in this gene result in white eyes because neither of the pigments is made. The other subunit of the guanine transporter is the product of the brown gene. Defects in this gene will only affect synthesis of drosopterin and the resulting eyes will be brown. The second subunit of the tryptophan transporter is encoded by the scarlet gene. Defects in that gene will block production of the brown ommochrome pigment and give rise to scarlet eyes because only drsopterin is present.

Examples of these three mutants are shown on the right from a paper by Mackenzie et al. (1999). The wild-type fly is the one at the lower left. Scarlet and white are on top and the brown mutant is in the lower right position.

Four other eye color mutants, Punch, purple, sepia and clot disrupt the activities of enzymes in the pathway from guanine to drosopterin (Kim et al., 2006).

Monday's Molecule #43

 
We have a winner!!! (see comments)


Today's molecule is a real biologically relevant molecule but it's a bit unusual. You have to supply the common name and the complete IUPAC name. There's an obtuse, indirect connection between this molecule and Wednesday's Nobel Laureate(s). (Hint: The Nobel Prize winner did not go to Sweden to get the prize.)


The reward goes to the person who correctly identifies the molecule and the Nobel Laureate(s). Previous free lunch winners are ineligible for one month from the time they first collected the prize. There are two ineligible candidates for this Wednesday's reward. Both of them are waiting to collect their prize this week or next week. The prize is a free lunch at the Faculty Club.

Send your guess to Sandwalk (sandwalk(at)bioinfo.med.utoronto.ca) and I'll pick the first email message that correctly identifies the molecule and the Nobel Laureate(s). Correct responses will be posted tomorrow along with the time that the message was received on my server. This way I may select multiple winners if several people get it right.

Comments will be blocked for 24 hours. Comments are now open.

PZ Rants About Science Textbooks

This is a posting about science textbook publishing. I have a vested interest in this debate because I'm the co-author of two biochemistry textbooks published by Pearson/Prentice Hall—one of the largest textbook publishers in the world.

PZ Myers posted an article about the high cost of textbooks [Textbooks, again]. He says,

Everyone in academia knows it: textbook publishers abuse the system. Jim Fiore decries the high cost of college textbooks, and I have to agree completely. Basic textbooks at the lower undergraduate levels do not need a new edition every year or two, not even in rapidly changing fields like biology.

There are two points here. The cost of textbooks is determined by the market and lots of other factors. As a general rule, the publishers are not making outrageous profits on individual college textbooks. They try to make their money on volume.

Most people don't understand that a large part of the cost of a textbook is due to the mark-up at the retailers. Much of the rest of the price is due to the cost of production and marketing. Look at the list of people who contribute to a textbook. You'll usually find them listed on the back of the title page. There are artists and editors as well as people who manage the project and people who market the books. Each new edition of a major textbook like biology can cost close to $1 million dollars these days. You have to sell more than 20,000 copies just to recover the production costs. (Really popular books will sell more than 100,000 copies but the difference isn't all profit.)

So let's understand and agree that the original price of a textbook is not unreasonable. My biochemistry textbook in 1965 was Conn & Stumpf and it cost $9.95. This works out to $65.80 in 2007 dollars using the handy-dandy inflation calculator on the US Dept. of Labor website. The 1965 textbook was much smaller, covered less material, and had no color figures. Modern biochemistry textbooks cost about $120-150 and they are very much better than the books published 40 years ago.

Even if we didn't want to make substantive changes in each edition and even if there were no second-hand market, we would still be forced to update our books because of pressure from competitors. Those other authors are hard at work revising and improving their books and if you don't follow suit you'll soon end up having no market share. What I'm saying here is that there are many reasons for new editions and it's very simplistic to attribute the cause to ripping off students. That's not how it works.

PZ's second point is more complex. Textbooks come out with new editions every few years. A typical cycle is four years—not the "year or two" that PZ suggests. While it is true that some of the pressure to produce new editions comes from a desire to eliminate the second-hand book market, that's not the only reason. There really is new material to add and new ways to approach the subject. In my case we're into the 4th edition of my Principles of Biochemistry textbook. The dates of publication are: 1992, 1996, 2002, and 2006. The next edition is scheduled for 2010. We're just about to start work on it. The differences between these editions are not trivial: they're part of a plan to transform the way we teach biochemistry. This is not unusual.

Churning editions is just a way for the publisher to suck more money out of a captive audience. It makes it difficult for students to sell off their used textbooks, it gives faculty the headache of having to constantly update their assignments, and if you allow your students to use older editions, it means we have to maintain multiple assignments. It's extraordinarily annoying, and to no good purpose at the university (to great purpose at the publisher, though).

This is simply not accurate. It's part of the urban myth about publishing. Everyone likes to blame someone else for the cost of textbooks.

I'm surprised that PZ would complain about having to update his assignments. You can't have it both ways, PZ. Either the new editions are trivial, in which case you don't have to change much, or they contain substantive changes, in which case your complaint about it being motivated to rip off students is unjustified. If you were using my textbook then be aware of the fact that my goal is to get you to change the way you've been teaching biochemistry. That's why I have new editions.

PZ, it sounds like you would never consider switching textbooks because it would be too much trouble for you to change your teaching. Is this a correct assumption?

On the plus side of their ledgers, though, I also urge the students to keep their textbooks once the course is over. These are valuable reference books that they may well find handy throughout their college careers and in their life afterwards. I've never quite understood the rush to dispose of those books the instant the semester ends — I kept my undergraduate biology and chemistry books until they fell apart (another gripe: the increasingly cheap bindings of these books), and I still have several of my old history texts on my shelves.

I'm with you on that one, PZ. I have all my old college textbooks. They are my friends. I never, ever, thought of selling them. They are full of notes in the margins and text highlights that reflect how I learned the material and what was important or controversial. I don't understand why students want to get rid of their textbooks when the course ends. Unless, of course, they never really cared about the subject in the first place and just needed a grade to graduate or get into medical school. But that's probably being too cynical.

AAAS Panel: Communicating Science in a Religious America

 
Matt Nisbet has organized a panel for the American Association for the Advancement of Science meetings in Boston next January. The title of the panel is Communicating Science in a Religious America. According to Nisbet's posting [AAAS Panel: Communicating Science in a Religious America], the panel will discuss framing. Here's the synopsis for the panel.

Over the coming decades, as society faces major collective choices on issues such as climate change, biomedical research, and nanotechnology, scientists and their organizations will need to work together with religious communities in order to formulate effective policies and to resolve disputes. A major challenge for scientists will be to craft communication efforts that are sensitive to how religiously diverse publics process messages, but also to the way science is portrayed across types of media. In these efforts, scientists must adopt a language that emphasizes shared values and has broad appeal, avoiding the pitfall of seeming to condescend to fellow citizens, or alienating them by attacking their religious beliefs.

Part of this process includes "framing" an issue in ways that remain true to the science, but that make the issue more personally meaningful, thereby potentially sparking greater interest or acceptance. With these themes in mind, the proposed panel combines the insights of scientists who have been successful at engaging religious publics with the findings of researchers on how media messages and opinion-leaders shape the perspectives of citizens. The panelists draw upon their experience working across the issues of evolution, climate change, stem cell research, and nanotechnology.

Who's on this panel, you might ask? It's some of the usual suspects and some others who I don't recognize.

... the panel features Brown University biologist Ken Miller, Vatican astronomer Brother Guy Consolmagno, William & Mary anthropologist Barbara King, Kansas science standards chair Steve Case, and University of Wisconsin communication researcher Dietram Scheufele. The panel is moderated by David Goldston, former chief of staff for the House science committee, now a lecturer at Princeton's Woodrow Wilson School and a columnist for Nature magazine.

As part of the panel, I will be presenting on the topic of "The New Atheism and the Public Image of Science," a first paper based on a research project I am currently working on here at American University with the help of two graduate students.

I have sent the following letter to Professor Goldston, the panel moderator.

Professor Goldston,

I have just read Matt Nisbet's blog article on the upcoming AAAS meeting in Boston.

As I'm sure you know, Nisbet has some very strong views on this issue and he is known to be a vocal opponent of athiests like Richard Dawkins, Christopher Hitchens, and Sam Harris. He has attacked the positions of many atheist scientist bloggers such as PZ Myers, Jason Rosenhouse, and me. He refers to this group as the "New Atheists," a term that is widely perceived as misleading at best, and offensive at worst.

Nisbet believes that scientists should spin their scientific messages in a way that avoids upsetting religious people and religious groups. That point of view has been hotly contested in the blogosphere. Many of us believe that this is a fundamentally dishonest way for scientists to behave. We believe that science should not be deliberately "framed" by the personal beliefs of scientists whether they are atheists - as are the majority of scientists - or Christians, or whatever.

We believe that science should be presented as uncompromised pure science and that it is wrong for scientists to consciously alter their message in order to appease religious citizens who might be offended by hearing the scientific truth. It is not the business of scientists to second guess what the religious public wants to hear, or not hear. Furthermore, it is not the business of scientists to tailor their message to the citizens of a particular country as the title of the panel implies. Is it realistic to expect scientists to communicate science one way in America, and another in Saudi Arabia, China, or France?

We all know there are scientists who have strong opinions about religion. Richard Dawkins is a vocal atheist, for example, and Ken Miller is a vocal Roman Catholic. Both of them have written books putting forth their points of view on religion. They are free to do so as long as they do not distort or misrepresent science.

But this is not what Nisbet is talking about when he refers to the public presentation of science - at least it's not what he should be talking about. Both Dawkins and Miller are perfectly capable of communicating scientific information without referring to religion, and they do so quite capably in many forums. Nisbet strongly implies that the Ken Millers of this world should be given preference over Richard Dawkins and other atheists when it comes to science education. This a form of censorship that should not be tolerated by AAAS.

I don't object to Nisbet presenting his point of view at a AAAS meeting but my respect for AAAS and your panel would be greatly diminished if the other side did not get a chance to make its case. Surely you do not want to give the impression that AAAS will only support scientists who agree with Nisbet? Surely you do not want to have a panel where the so-called "New Atheist" perspective is excluded and only religious scientists, or their close allies, are allowed to speak? Is that fair?

Please make sure that you have appropriate balance on your panel. Please make sure you don't give the impression that AAAS endorses Nisbet and his ideas about framing. The other side needs to be heard.

Who Is David Tyler?

 
In an earlier posting, I quoted David Tyler's views about evolution and the peppered moth story [Peppered Moths and the Confused IDiots]. I didn't know who David Tyler was but he's obviously considered to be an authority (i.e., prominent IDiot) by Denyse O'Leary, among others.

Since posting that article, I've become more informed about this man. I thought I'd share this information so that everyone will know who's considered to be a leading IDiot on evolution.

David Tyler is a Young Earth Creationist who belongs to The Biblical Creation Society. Tyler believes in the literal truth of Genesis. It's no wonder that he has some doubts since there's nothing in Genesis about peppered moths.

Tyler has a day job. He is a Senior Lecturer (Professor, in North American terms) in the Department of Clothing Design and Technology, Hollings Faculty of Food, Clothing & Hospitality Management, Manchester Metropolitan University [Homepage for David J. Tyler]. He has a Ph.D. in physical sciences and his current interests focus on the textile industry, according to the Manchester Metropolitan University [Dr. David Tyere].

After joining the Department of Clothing Design and Technology at Manchester Metropolitan University, he has pursued a number of research interests related to responsive manufacturing and systems modelling. Earlier work was concerned with flow line systems and management strategies to optimise performance. Research interests over the past decade relate to teamworking in new product development and its relation to operational practices, and the optimisation of performance of textile/apparel supply chains. Since March 2000, he has managed the North West Advanced Apparel Systems Centre, a European-funded initiative to support clothing and textile companies in NW England.

This is an example of the sort of expert the IDiots think is a good spokesman for Intelligent Design Creationism: a Young Earth Creationist (YEC) with no obvious background in biology.

I really don't understand people like Denyse O'Leary and some of her friends. Denyse is Roman Catholic. She is not a Young Earth Creationist. How can she put any faith in the credibility of a man who thinks that science is compatible with a 6000-year-old Earth?

Parsing John Pieret

 
John Pieret has posted an intersting article in which he criticizes Mary Jordan for writing something silly about atheists in the Washington Post [Harebrained Hairpins]. I agree with John that she went way overboard.

However, I'm more interested in John's opening paragraph where he repeats a position he has long mantained.

I'm not overly sympathetic to the complaints of the "New Atheists" that they are unfairly being told to mute their criticism of religion lest they drive religious people further away from science in particular and rationalism in general. In my opinion, science is definitely not coextensive with atheism. And atheism, far from having a lock on rationalism, is, in fundamental ways arational, at least, if not outright irrational at times. And, it seems to me, if a dialogue is what you intend in which you hope to convince the religious to become atheists, starting off calling them delusional may be a tad counterproductive.

This is a bit confusing. Let's see if we can parse the sentences to get at the essence of John's problem. If I understand him correctly, he is saying ...

It is fair to tell atheists to mute their criticism of religion because it might be driving religious people away from science.

How, exactly, does this work, John? What is the ethical reasoning that justifies telling someone to keep quiet because you don't like their message? There is none. It's pefectly okay to disagree with us—something you do quite often—but it's a whole different thing to tell us to shut up, and maintain that it's fair to do so. It's not fair. It's unfair, ... and reprehensible.

If there's a rational argument there, then it has to be something like the following. You believe that religious people are going to embrace science—a good thing—but they won't do it if we atheists start telling them that there's no such thing as God or miracles. Hmmm ... very interesting. Does it also apply to other groups? Will astrologers embrace science as long as we stop telling them that astrology is a bunch of superstitious nonsense?

I interpret John to be saying.

It is fair to tell atheists to mute their criticism of religion because it might be driving them away from rationalism.

John, Aren't you making an unwarranted assumption here? Aren't you assuming that the average religious person already embraces rationalism? Otherwise, how could they be driven away?

What exactly are you saying? Are you saying that by criticizing religion we are making religious people abandon rationalism? And if we stop the criticism they will become rational? What arguments do you use to support that claim?

In my opinion, science is definitely not coextensive with atheism.

I agree. "Science" and the lack of belief in supernatural beings are two different things. It is possible to avoid believing in supernatural beings and be opposed to science. There are many examples. In addition, there are some people who fully accept all the fundamentals of science, and its implications, while still being religious. Deists are one example. Buddhists are another.

And atheism, far from having a lock on rationalism, is, in fundamental ways arational, at least, if not outright irrational at times.

The atheists are saying that they don't buy into the superstitious belief in the existence of supernatural beings. They don't accept most of the basic tenets of the major religions because they are not based on evidence. How in the world is this "irrational"?

And, it seems to me, if a dialogue is what you intend in which you hope to convince the religious to become atheists, starting off calling them delusional may be a tad counterproductive.

The evidence so far is against you. We've never had so much dialogue between atheists and religious leaders as we've had since the publication of The God Delusion. It is no longer possible for religious people get away with making the unchallenged assumption that there is a God. Millions of people are hearing for the first time that their core belief is being questioned. Not only that, it's being questioned in a particularly forceful way. That makes you sit up and take notice.

I'm sick and tired of this phony argument. It is completely irrational.

Casey Luskin Lies about Dawkins

 
I know, I know, so what else is new?

But this lie is so outrageous that it just has to be exposed. Over on the Discovery Institute website, Casey Luskin gloats over the famous video where Richard Dawkins pauses for 11 seconds when asked to give an example of an evolutionary process that increases information in the genome [Richard Dawkins on the Origin of Genetic Information].

The explanation for this pause is well-known. Dawkins had just realized that he had been duped into giving an interview in his house by creationists from Australia. The pause was to collect his thoughts after realizing the dishonesty of the interviewers. He then asked that the cameras be turned off and he asked them to leave. You can see the video and read the essay Dawkins wrote on dozens of websites [see Creationist Delusions about Transitional Fossils and Information].

Casey must know about this. He can't be that stupid. Therefore, he is lying.

Peppered Moths and the Confused IDiots

I'm teaching part of a course on Popular Scientific Misconceptions. In my section we'll be talking about the evolution/creationism controversy and part of the discussion involves analysis of the techniques used by Jonathan Wells to denigrate evolution in his book Icons of Evolution. One of the chapters is Peppered Moths.

Creationists used to love the peppered moth story because they thought the evidence had been refuted by modern science. They were wrong, and most creationists will admit it. Not Jonathan Wells. He says,

Industrial melanism in peppered moths shows that the relative proportions of two pre-existing varieties can change dramatically. This change may be due to natural selection, as most biologists familiar with the story believe. But Kettlewell's evidence for natural selection is flawed., and the actual causes of the change remain hypothetical. As a scientific demonstration of natural selection—as "darwin's missing evidence"—industrial mealanism in peppered moths is no better than alchemy.

Open almost any biology textbook dealing with evolution, however, and you'll find the peppered moth presented as a classical demonstration of natural selection in action—complete with faked photos of moths on tree trunks. This is not science by myth-making.

Unfortunately for poor old Jonathan, the original work of Kettlewell has been replicated and natural selection is the explanation. The creationists were recently dealt a serious blow when Michael Majerus reported the results of his observations on peppered moths to the European Society for Evolutionary Biology. So what do they do now?

Denyse O'Leary thinks there's still propaganda to be made from the peppered moth story so she links to an article from last week that shows the new strategy. Denyse's link is here [Evolution in the light of intelligent design encyclopedia - new entries]. The article by David Tyler is The Peppered Moth: when will Darwinians admit that mistakes have been made?.

I'm going to quote part of David Tyler's article. I swear I'm not making this up.

The concluding words of Majerus' lecture are these: "If the rise and fall of the peppered moth is one of the most visually impacting and easily understood examples of Darwinian evolution in action, it should be taught. It provides after all: The Proof of Evolution." This quote explains why the issue is still important: Darwinists have always sought to use the peppered moth story as a proof of Darwinian evolution. This is a burden that cannot be carried by the evidence. Even with Majerus' new improved methodology, we have an example of natural selection within the peppered moth population with differential predation being the causal mechanism. It is an extraordinary mental leap to go from this to the origin of novelty, complexity and new body plans - which remain the central challenges for any theory of evolutionary transformation.

Okay, let's take this slowly so that even IDiots like David Tyer and Denyse O'Leary can understand.

It is absolutely safe to say that if you meet somebody who claims not to believe in evolution, that person is ignorant, stupid or insane (or wicked, but I’d rather not consider that).

Richard DawkinsWhen people like Majerus talk about evolution they're talking about the process of evolution. In this case he's referring to the process of evolution by natural selection within populations. He is perfectly correct in saying that the peppered moth date is proof that evolution occurs. It's proof of Darwinian evolution.

The problem with the IDiots is that they don't even understand what evolution is. Evolution does not require the creation of new body plans and the peppered moth example does not pretend to account for such things directly. All it does is show that evolution by natural selection is an observable fact.

Is it scientifically defensible to find an example of natural selection within a population of an animal, and then use this as an evidence for evolutionary transformation from the first single cell to the extraordinary diversity of life that we find in the biosphere?

No.

When this simple question is answered with a negative, then we can have a more constructive dialogue.

David, or Denyse, I'm ready whenever you are. To start with, do you understand the minimal definition of evolution [What Is Evolution?]. Get back to me when you do.
