PNAS Publishes Bio-Terrorism Paper

The Proceedings of the National Academy of Sciences has decided to publish a paper that the Department of Health and Human Services had asked to be withheld. The paper is a mathematical model of a terrorism scenario where botulinum toxin is released into the milk supply. The paper is accompanied by a commentary by Bruce Alberts, the president of the National Academy of Sciences, explaining why they chose to publish the paper. (I briefly blogged about this previously.)

Continue Reading


Alberts makes two arguments supporting the publication of terrorism-related articles in the open scientific literature. The first is that the information becomes available to a wide variety of scientists who can criticize and build on the findings, potentially leading to new and better ideas that would not otherwise be predicted. The second is that people should be aware of real dangers. "If the types of calcuations and analyses in the Wein and Liu article are carried out only by government contractors in secrecy, not only are the many actors in the U.S. system who need to be alerted unlikely to be well informed, but also the federal government itself may become misled--either greatly overestimating or underestimating the seriousness of a particular danger relative to other concerns." Apparently due to its wide circulation in preprint form, some are already beginning to challenge aspects of the paper.

The committe that decided to publish the paper looked at a number of criteria in considering the issue. For a given pathogen, does the paper:

1. Show how to makea vaccine ineffective?
2. Give resistance to therapeutics?
3. Enhance virulence?
4. Increase transmissibility?
5. Alter the host range?
6. Allow evasion of detection?
7. Enable weaponization?

They determined that this paper did none of these things, and that all of the critical information is easily obtainable on the internet.

The paper is available for free. Here is the abstract:

We developed a mathematical model of a cows-to-consumers supply chain associated with a single milk-processing facility that is the victim of a deliberate release of botulinum toxin. Because centralized storage and processing lead to substantial dilution of the toxin, a minimum amount of toxin is required for the release to do damage. Irreducible uncertainties regarding the dose-response curve prevent us from quantifying the minimum effective release. However, if terrorists can obtain enough toxin, and this may well be possible, then rapid distribution and consumption result in several hundred thousand poisoned individuals if detection from early symptomatics is not timely. Timely and specific in-process testing has the potential to eliminate the threat of this scenario at a cost of <1 cent per gallon and should be pursued aggressively. Investigation of improving the toxin inactivation rate of heat pasteurization without sacrificing taste or nutrition is warranted.
The Alberts commentary is available here, but may require a subscription at this time.

B.H. Roberts on Evolution

Gospel and Man's Relationship to Deity, a book written by B.H. Roberts, was first published in 1888 with new editions released as a late as 1924. In a "Supplement" at the end of the book, Roberts takes on the topic of evolution. It is clear from his discussion that Roberts did not accept evolution for reasons having to do with both theology and science. Since there were multiple editions of the book, I do not know whether the supplement was included from the beginning or was added later, however it appears that he eventually did modify some of his thinking on the matter (see below).

Continue Reading


The Supplement is interesting for at least two reasons. First, it shows what Roberts thought about evolution (as understood at the time). Second, Roberts lays out a number of arguments that persist to this day. The Supplement is too long to reproduce here, but I will provide the most relevant passages. Since it is such a readily accessible resource, I will also provide links to counter-arguments made on Talkorigin.com's Index to Creationist Claims. I will also add a few comments of my own. In doing so I intend no disrespect toward Roberts--as the 1931 controversy and other aspects of his life show, he was a man of both spiritual and intellectual integrity. I do not, however, believe that we do Roberts any honor by not providing answers to his objections.

The state of science has progressed immeasurably since Roberts first published this book--or even since he died. Think of the concepts of radioactive decay, genes, plate tectonics, the structure and coding of DNA, molecular biology, and genomics--the majority of these did not even exist in Roberts' lifetime and those that did were still in their infancy. These concepts have brought us an unprecedented understanding of the world we live in--an understanding that is increasingly harnessed by technology for practical benefit. I wonder what Roberts would say today.

Excerpts from the Supplement (page numbers are included):

p.265 What do these facts prove, I mean the sterility of species and hybrids on the one hand, and fertility of varieties, descendants from a common stock, on the other? Why, that the great law of nature is, as announced in holy writ, that every seed shall produce after its kind, and every fish, fowl, creeping thing, beast, and man shall bring forth after his kind-that is what it proves. And though man may for a moment by crossing species cause a slight deviation from the great law, it can be but for an instant, the monstrosity cannot be perpetuated, it dies out by being made unfruitful.

How do these facts affect the theory of evolution? Let us remember upon what that theory rests. It rests upon the principle that lower forms producing favorable variations, and these being preserved by the process of natural selection, amount finally to the production of distant species; but we have seen that varieties cannot produce what may be called the great characteristic of species-infertility to each other; then also we have seen there is a check to variation in the sterility of species and hybrids. Add these facts to that other fact that neither in living nature nor in the geological records can be found the intermediate transitional forms linking together by fine gradations the species, and the theory of evolution as advocated by many modern scientists lies stranded upon the shore of idle speculation.

Now that the basis of heredity and genetics are better understood, Roberts' objections are consistent with, if not outright supportive of, evolution. The more closely related two species are, the more likely it is that they can produce a hybrid (not all hybrids are sterile, by the way). Inability to produce a hybrid means that the reproductive isolation is complete. This is a matter of genetics, not a supernatural law governing variation.

Evolution has not been proved.
Mutations do not produce new features.
Range of variation is limited within kinds.
Evolution predicts a continuum of organisms, not discrete kinds.
Transitional fossils are lacking.
There should be billions of transitional fossils.
Science cannot define "species."

p.266 But if the hypothesis of evolution be true, if man is only a product evolved from the lower forms of life, better still producing better, until the highest type of intellectual manhood crowns with glory this long continued process-then it is evident that there has been no "fall," such as the revelations of God speak of; and if there was no fall, there was no occasion for a Redeemer to make atonement for man, in order to reconcile him to God; then the mission of Jesus Christ was a myth, the coinage of idle brains, and Jesus himself was either mistaken, or one of the many impostors that have arisen to mock mankind with the hope of eternal life.

There are two crucial links in reasoning here, and in many other theological treatments of evolution. The first is that the Fall of Adam and Eve is incompatible with evolution. The second is that without the Fall, the Atonement is unnecessary. I would like to deal with these in a future post. For now I will just say that I believe that these objections can be overcome. (If the first is overcome, the second is moot.) It is self-evident that we are subject to physical death. It is also self-evident (to most people) that we are not in the presence of God. Since the purpose of the Atonement is to overcome these two things, I think that how they came to be is of secondary importance, theologically. I hope to expand on this in a future post. Although the index treatment of this is unsatisfactory to me, it at least gives something to think about.

Without a literal Fall, there is no need for Jesus and redemption.

p.267 I am aware that there is a class of men who profess to be "Christian evolutionists," and who maintain that Christianity can be made to harmonize with the philosophy of evolution. But how are they made to harmonize? We are told that Jesus is still a Redeemer, but in this sense only: he gave out faultless moral precepts, and practiced them in his life, and inasmuch as people accept his doctrines and follow his example they will be redeemed from evil. But as to the fall of man and the atonement made for him by the Son of God-both ideas are of necessity rejected; which means, of course, denying the great fundamental truths of revelation; it is by destroying the basis on which the Christian religion rests, that the two theories are harmonized-if such a process can be called harmonization. It is on the same principle that the lion and the lamb harmonize, or lie down together-the lion eats the lamb.

If this is the best harmonization that can be accomplished, we do have a problem. While this may be the solution for some, I think the options presented here are a false dichotomy. See above.

p.279 The Prophet Joseph Smith is credited with having said that our planet was made up of the fragments of a planet which previously existed; some mighty convulsions disrupted that creation and made it desolate. Both its animal and vegetable life forms were destroyed...

p.281 Accepting this statement of Joseph Smith relative to our planet in its present state being created or formed from the fragments of a planet which previously existed, one may readily understand how the supposed differences between scientists and believers in revelation have arisen. Scientists have been talking of the earth's strata, that were formed in a previously existing planet; they have considered the fossilized flora and fauna embedded in those strata, and have speculated as to the probable lapse of time since those animal and vegetable forms of life existed; and have generally concluded that the age is so far remote that there is no possible chance of harmonizing it with the account of the creation as given in the Bible. Believers in the Bible, on the other hand, have generally taken it for granted that the account of the creation in the sacred record would give to the earth no greater antiquity than six thousand years; and have held that within that period the universe was created out of nothing by the volition of Deity-an idea so palpably absurd that intelligence, despite all church authority to the contrary, everywhere rejects it.

The theory set forth in this writing that before Adam was placed upon this earth to people it with his offspring, the matter of which it is composed existed in another planet, which by some mighty convulsion was broken up, and from its ruins was formed our present earth, at once affords a means of harmonizing those facts established by the researches of men and the facts of revelation. If scientists shall claim that myriads of years or of centuries must have been necessary to form the earth's crust, it may be allowed by the believers in revelation, for there is nothing that would contradict that idea in the revelations of God on the subject. If scientists shall claim that the fossilized remains in the different strata of the earth's crust reveal the fact that in the earlier periods of the earth's existence only the simpler forms of vegetation and animal life are to be found, both forms of life becoming more complex and of higher type as the earth becomes older, until it is crowned with the presence of man-all that may be allowed. But that this gradation of animal and vegetable life owes its existence to the process of evolution is denied. As before stated, the claims of evolution, as explained by philosophers of the Darwin school, are contrary to all experience so far as man's knowledge extends. The great law of nature is that every plant, herb, fish, beast and man produces its kind; and though there may be slight variation from that law, those variations soon run out either by reverting to the original stock, or else by becoming incapable of producing offspring, and thus become extinct.

Furthermore, since we have learned that God made "every plant of the field before it was in the earth, and every herb before it grew" (i. e. in our earth), the gradation of life forms which the naturalists discover in the various strata of the earth's crust may reasonably be accounted for aside from the theory of evolution-viz., by the animal and vegetable life forms of some older earth being brought to our own; different species being transplanted as changed conditions in the soil and atmosphere and temperature of our earth rendered it favorable to their productions, the older species becoming extinct as the changed conditions of the earth became unfavorable to them.

Then too, the theory advanced in this writing gives ample room for the reconciliation of another serious difficulty between the scientist and the believer in revelation. To the latter Adam is the first man; the former maintains that there are evidences which prove the earth to have been inhabited before Adam's time. Whether or not the planet which existed previous to our own, and out of the ruins of which our own was organized was inhabited by man as well as by vegetation and animals, I cannot say; all remarks on this subject would be conjecture merely. But if the researches of scientists prove beyond all question that there were pre-Adamic races, then doubtless they were inhabitants of that world which was destroyed, but the evidence of their existence as well as the evidence of the existence of animals and vegetation was preserved in the re-creation of that planet to form this earth. Though, in this connection, I must say that so far as I have examined the works of those who treat on the subject of pre-historic man, or pre-Adamic races, they have hung the heaviest weights on the slenderest of threads: and I am inclined to the opinion that Adam was the progenitor of all races of men whose remains have yet been found.

The claim that the age of the earth and the fossil evidence can be explained by the earth having been formed from previous planets that were broken is unique, I think, to Latter-day Saints. I will defer discussion of this claim to my next post. I would just note that one of the reasons The Truth, The Way, The Life was not published by the Church was because it assumed life and death had occurred on this earth before Adam and Eve. Thus it appears that Roberts did not stick to the argument laid out above.

The statement by Roberts that "the claims of evolution...are contrary to all experience so far as man's knowledge extends" is telling. I think that many arguments against evolution really boil down to this sentiment. It is what Richard Dawkins calls "The Argument from Personal Incredulity." However, the truth or accuracy of scientific concepts does not lie in whether they are intuitive or not. Quite the contrary--science is full of counter-intuitive ideas. For example, even a casual exploration of physics will uncover concepts that have no resemblance to our day-to-day lives. We are used to it now, but there is nothing immediately intuitive about how microorganisms cause disease--the etiology of infectious diseases has been unknown for most of history. The germ theory of disease was deemed absurd by some skeptics. Examples could be multiplied--the point is that our daily experience is not always the best way to judge such things.

As for the transplantation of life on earth from a another planet, this is a common idea found in LDS circles--I'm not sure whether it is found in the broader Christian tradition. The history of this concept within Mormonism would be interesting--something I may investigate later. For now I will just say that the idea that most life-forms were transplanted from another place does not really solve any problems. First, it does nothing to answer the question of how the life-forms were created. It merely moves the question back to another place. It also fails to explain the evidences from biogeography, the fossil record, and molecular evidences of common descent. Whether the original life on earth was a transplant is something that probably cannot be ruled out by present evidence, but that is another matter. If transplantation of life from elsewhere has occured we currently have no evidence for it, and for large-scale transplantation, we have much evidence against it.

Macroevolution has never been observed.

Congressional "Oversight"

In an attempt to safeguard the public interest, Representative Randy Neugebauer (R-TX) introduced an amendment to a spending bill, that passed in the House, that prevents NIH from funding two specific grants. What is the research that Neugebauer finds so unworthy, something about sex? Suprisingly, no. One concerns the role of self-esteem in marriage and the other, perception and cognition in pigeons.

Continue Reading


From Neugebauer's website:

One of the studies has been ongoing for nearly 15 years and has received more than $1.5 million to study “Perceptual Bases of Visual Concepts.” This study examines how pigeons can classify lifelike visual stimuli into natural and artificial categories.

Now on its fifth year, a second study has spent more than $745,000 to determine how the self-esteem of newlyweds affects their marriage. According to the NIMH, this study examines how “the activation of felt security affects newlyweds’ capacity to engage in behavioral regulation strategies critical for marital satisfaction.”

“I am a fan of marriage,” Neugebauer said. “In fact, I have actively participated in one for 35 years. However, despite any scientific merits this research may have, it fails to contribute to the effort to find cures for Alzheimer’s, autism, or any other serious mental health disease.”

Neugebauer is also concerned that these two grants are being supported at the expense of more important research.

“Sending millions of dollars to research that falls outside the mission of NIMH is problematic enough,” Neugebauer said. “However, this problem is compounded when you look at the list of grants that have been rejected over the same time period. If you look at the list, you will find grant after grant which specifically targets serious mental health diseases, such as schizophrenia and bipolar disorder.”

It isn't clear why he zeroed in on these two grants. It also is not clear why he has made it his business to decide which grants should be funded and which should not. NIH grants are generally not easy to get--in fact the median age for a researcher to obtain their first competetive NIH grant is 42. NIH grants go through a tough peer review process--one that is not just a rubber stamp, since most grant applications are rejected.

From the Coalition to Protect Research:
NIH is the premier biomedical and behavioral research institution in the world. Its mission is to support science to improve the health and well-being of all humanity. At a time when genetic control over diseases is tantalizingly close but not yet possible, knowledge of the behavioral influences on health is a crucial component in the nation’s battles against the leading causes of morbidity and mortality. Appropriately, NIH supports a large and robust portfolio of research on all aspects of human development and disease.

Contrary to the assertion that NIMH’s mission should focus solely on severe mental illnesses, and away from promoting mental health, the Public Health Service Act (Report 102-546) provides a clear picture of congressional intent regarding NIMH’s mission: “The research program established under this subpart shall include support for biomedical and behavioral neuroscience and shall be designed to further the treatment and prevention of mental illness, the promotion of mental health, and the study of psychological, social, and legal factors that influence behavior…”

It is certainly Congress's perogative to determine funding and set priorities, but for one Congressman to decide that a couple of grants should not be funded because he/she thinks it is wasteful is bad practice and policy, in my opinion.

Dawkins on the Supernatural and Nature

The Ancestor's Tale, by Richard Dawkins, has very little to say about religion. There are a few warnings to creationists not to distort particular arguments, and he mentions Kenneth Miller's (religious and scientific) objections to intelligent design, but that is about it. There is, however, an interesting passage at the close of the book. (Spoiler Alert: What follows comes from the very end of the book. If this will bother you, don't read further.)

Continue Reading


At the closing of the book, Dawkins writes:

I have not had occasion here to mention my impatience with traditional piety, and my disdain for reverence where the object is anything supernatural. But I make no secret of them. It is not because I wish to limit or circumscribe reverence; not because I want to reduce or downgrade the true reverence with which we are moved to celebrate the universe, once we understand it properly. 'On the contrary' would be an understatement. My objection to supernatural beliefs is precisely that they miserably fail to do justice to the sublime grandeur of the real world. They represent a narrowing-down from reality, an impoverishment of what the real world has to offer.

I suspect that many who call themselves religious would find themselves agreeing with me. To them I would only quote a favourite remark that I overheard at a scientific conference. A distinguished elder statesman of my subject was having a long argument with a colleague. As the altercation came to an end, he twinkled and said, "You know, we really do agree. It's just that you say it wrong!"

My guess is that what Dawkins says here will resonate with some, while others will find it mistaken at best and blasphemous at worst. Does Dawkins have a point here or is he mistaken? In what ways does religion tend to cheapen or enhance our view of the physical world and the universe?

Review of The Ancestor's Tale


I recently finished reading The Ancestor's Tale by Richard Dawkins, which is his latest book. For many, Dawkins needs no introduction. The zoologist has been one of the largest popularizers of evolution and has sparked controversy due to his atheism. If you are interested in evolution, Dawkins is a must-read. The Selfish Gene and The Blind Watchmaker are probably his most well-known books to date. The Ancestor's Tale is a welcome addition to my library. Since I plan to use some of it as material for future posts, I will not discuss much of the content here.

Continue Reading


The Ancestor's Tale is patterned, in a fashion, after the Canterbury Tales. As travelers to the beginning of life on earth, Dawkins escorts us backward in time and enlists organisms along the way to tell tales that teach us about some aspect of biology. The book covers a wide range of topics, though not exhaustively or else the book would be much larger than the 600+ pages it already is. Although further discussion and details are certainly warranted on many topics, the scope and size of the book forces Dawkins to move along. (Dawkins can be long-winded at times.) Dawkins' intent in arranging the book in reverse-chronological order is to avoid the impression that humans were the destined outcome of evolution. Be that as it may, I think the arrangement is helpful in another sense as well--it starts the reader on terrain they are already familiar with and then moves to the less familiar.

One advantage of dividing the book into individual tales is that a particular organism can be used as an example of the topic at hand. Sometimes the topic is important for all descendants of that particular organism, so the sense of context is nice. There are, however, a couple of disadvantages to this arrangement. Some of the tales are empty of any real content--they simply serve as fillers in the tree of life. Also, at times there is no particular reason to associate the message of a particular tale with the organism at hand. Since the table of contents only lists the organisms telling tales, you'll probably have to go to the index to find where any particular topic is discussed. I found it helpful to annotate the table of contents with a short description of the main point of each tale.

In terms of content, I have little to say because Dawkins certainly knows more than I do about many things. I only have one critique concerning information not covered: I think a discussion of the evolution of the immune system would have gone along nicely with the discussion of globin gene duplication in "the lamprey's tale." As far as topics to be left out, well one thing I like about Dawkins is his willingness to take on politically incorrect topics. However, there are two or three cheap-shots taken at U.S. presidents that I think should have been left out. Two of the comments were in reference to the current war in Iraq. I think that, regardless of politics, these comments were distracting from the discussion (I don't remember any criticism of his own country's leadership, but perhaps I did not notice) and served no purpose other than to let his opinion be known.

One additional complaint: there are very few endnotes, and the ones that do appear are for illustrations or figures. In order to find references, you have look up a topic or person in the index to find a number that corresponds to a reference in the bibliography. While this may make the text more aesthetically pleasing, it is cumbersome if you want to find references for Dawkins' claims.

Is this book for you? Well I definitely recommend it. However, if you have not read about biology and evolution before, I recommend reading another book first--perhaps one of Carl Zimmer's books. I think you will gain more from this book if you are already somewhat familiar with biology beforehand. If you are unfamiliar with animals or concepts in the book, I recommend you take time to learn more on the internet. Certainly religious people will have some disagreements with Dawkins, but don't let that get in the way. While you may not agree with Dawkins on all issues, I think it is worth your time to hear the man out. Most likely, he will teach you something.

Things to Think About, Or Not

I'm leaving town for a few days, so I doubt that I will be able to do any blogging until the middle of next week. So here are a couple of interesting links to check out in the meantime.

First up is a post at Pharyngula on placentas and preeclampsia in women. The processes of pregnancy can also be viewed as a struggle between a parasite and its host. Taking evolution into account can help illuminate these processes. The post also links to this article by Carl Zimmer which uses preeclampsia (scroll about half way down) as an example of how evolution could provide insights into medicine.

Then (via Pharyngula) there is this post which tears into a recent article on Salon.com about vaccines and autism.

And then there is, um....this photo of the week from National Geographic News.

Brains! Braiiiins!

From John Hawks Anthropology Weblog comes this. Toxoplasma gondii is a parasite that is commonly carried by cats. Pregnant women know about it because it can cause birth defects if it infects a developing fetus. It looks like it may also have an effect on human behavior. This was new to me, so I did a quick search and found this article suggesting that it may play a role in some cases of schizophrenia (it mentions bipolar disorder too). I've never been fond of cats--this doesn't help. (For more information on T. gondii and toxoplasmosis see here and here.)

Carl Zimmer has a post on the evolution of brain size in bats and its connection to the current controversy over Homo floresiensis. Apparently bat brains vary in size, as related to total mass, depending on their niche. Zimmer suggests that maybe it should not suprise us if some hominids decreased in brain size.

Sen. Buttars is Disowned by Discovery Institute

Justin at Mormon Wasp alerted me to two articles in the Salt Lake Tribune about the current controversy over evolution in Utah. Let's get right to it.

Continue Reading


The first article contains several items of interest.

Evolution has not been a big issue in Utah until now. On June 3, Sen. Chris Buttars of West Jordan said he would propose giving equal time to what he called "divine design," that is, that the world was created by a superior being.
"The divine design is a counter to the kids' belief that we all come from monkeys. Because we didn't," the conservative Republican told The Salt Lake Tribune.

But proponents of intelligent design have a message for Buttars: Don't help us.

"We get very upset when supposed friends are claiming far more than what the scholars are saying," says John West, associate director of the Discovery Institute's Center for Science and Culture in Seattle.

For one thing, they oppose requiring the teaching of intelligent design. What they are pushing, West says, is a thorough discussion of Darwinian theories which would include criticism raised by legitimate scientists.

That's what the schools in Ohio and Minnesota have done and what intelligent design advocates hope will happen in Kansas, he says. But they don't support the move in Dover, Pa., to add a statement about intelligent design to the curriculum. And they want nothing to do with Buttars' so-called "divine design."

"We wish [Buttars] would get the name right and not propose something he doesn't understand," West says.
That the Discovery Institute would disown Buttars is not suprising. They haven't really produced anything scientifically helpful so the DI has to be careful for legal and political reasons. They have to keep themselves distanced from "creation science" and faith-claims or else they will lose court battles. But the distance of separation is rather thin and everyone knows it is only there out of legal necessity. Somehow I doubt Buttars will suffer politically for this, but if he does it can only be attributed to his ignorance, not only of his opposition, but also of his "friends."
On the home front: It is not clear when or if the intelligent design movement will find its way to Utah. Buttars said this week that he was prompted into action by calls from concerned parents who claimed their children were being taught that humans descended from apes.

"That's got to stop," Buttars says. The truth is: It never began.

"We base our teachings solely on evidence," says Patty Harrington, Utah's Superintendent of Schools. "And there's no empirical evidence man has sprung from the apes."

Darwin believed apes and humans did have a common ancestor, Ann Story tells students in her biology classes at East High School in Salt Lake City, but that billions of years ago, apes went one way and humans another.
This bit from Buttars gets my blood pressure up--I'll reserve comment. As for Harrington's quote, I don't know what to make of it. It is technically correct, but it walks the line between supporting and opposing common descent. Ann Story's quote is also potentially misleading, aside from the fact that the time frame is wrong. (Six million years ago, if I remember correctly, is the time of the split with chimpanzees.)
"Creation science," as it was called, began in the 1920s with a Seventh-day Adventist geologist named George McCready Price, who claimed the Earth was actually much younger than scientists thought. Noah's flood first killed smaller animals, followed by vertebrate fish, and finally larger animals and man, [Price] wrote in 1923's The New Geology. He argued that all these creatures lived at the same time, making any claims about an ancient Earth from the multilayered fossil record a fiction.
Price's arguments and reasoning influenced Joseph Fielding Smith. It was Price who laid out the reasoning of no fall--no atonement(1). The two corresponded and Smith encouraged Price in his work. The arguments of Price were a topic of discussion during the deliberations over the doctrinal dispute between B.H. Roberts and Joseph Fielding Smith concerning pre-Adamites. James E. Talmage enlisted his son, Sterling, also a geologist, in attacking Price's credibility. (See my post, The B.H. Roberts Episode.)

The second article is worth a read also. One section of note:
The official LDS Church position has remained steady from a 1931 First Presidency statement to a 1993 packet handed out at BYU students: "Leave geology, biology, archaeology and anthropology, none of which has to do with the salvation of the souls of mankind, to scientific research."

Teachers at LDS high school seminaries "are encouraged to discuss with their students principles about the divine nature of human life as taught in the scriptures and in official declarations of church doctrine from the First Presidency," said church spokesman Dale Bills. "They are cautioned not to debate the theory of evolution."

According to a 2002 book, Where Darwin Meets the Bible, LDS Church President Gordon B. Hinckley shares that view. Recalling his own study of anthropology and geology, Hinckley said, "Studied all about it. Didn't worry me then. Doesn't worry me now." Such openness has meant that several BYU scientists have produced important research in the field of dinosaurs, anthropology and evolution.


The speech by Michael Whiting that is mentioned is available here.

Update:
1. This may not be quite right. It is apparent from previous writings by B.H. Roberts that evolution was seen as a threat to the connection between the Fall and the Atonement.

Religion at the Zoo?

About a month ago, George Will wrote a column which included this paragraph:

Some Christians should practice the magnanimity of the strong rather than cultivate the grievances of the weak. But many Christians are joining today's scramble for the status of victims. There is much lamentation about various "assaults" on "people of faith." Christians are indeed experiencing some petty insults and indignities concerning things such as restrictions on school Christmas observances. But their persecution complex is unbecoming because it is unrealistic.

This story from CNN.com might be the kind of thing Will is talking about.
The Tulsa Zoo will add a display featuring the biblical account of creation following complaints to a city board about other displays with religious significance, including a Hindu elephant statue.
Get out of here! A Hindu elephant next to the elephant display?

NCSE on Utah and ID

The National Center for Science Education released an news brief about the push for the inclusion of intelligent design (or "divine design", as Sen. Buttars unwisely called it) in public schools. It summarizes a couple of newspaper articles, and editorials in reaction.

Utahns concerned about the threatened "divine design" legislation are encouraged to get in touch with Duane Jeffrey, a professor of biology at Brigham Young University and a member of NCSE's board of directors, at duane_jeffery@byu.edu.


Another interesting excerpt:
The Eagle Forum's Ruzicka explained her motivations for supporting the threatened legislation: "What an insult to teach children that they have evolved from a lower life to what they are now, and then they go home and learn that they are someone special, a child of God. ... This is not right."

I can see Ruzicka's point of view. But while we're talking about insults, oh nevermind.

BYU Biology Faculty Quoted

I was reading Red State Rabble (here and here) and saw that BYU was mentioned. The reason was because of an article in MetroWest Daily News titled God, science and "Intelligent Design." The article quotes three BYU (Provo) faculty, as well as some other religious scientists. I'm providing the relevant passages, but you'll have to read the article for more context.

Likewise, Keith Crandall, professor of integrative biology at Brigham Young University, says that many freshman walk into his biology classes believing Mormonism dictates creationism, unaware that church leadership articulated a policy of no position on evolution in 1925. Crandall describes the process by which he teaches evolution using his own research on HIV mutations which select for drug resistance, and, in companion discussion, illustrates how core creationist arguments differ from orthodox Mormon theology. Nevertheless, says David McClellan, also a biology professor at BYU and a practicing Mormon, if the subject comes up in a discussion at church, "I still get a few people telling me it's `Evil-Lution.'"

That part about no position since 1925 may not be quite accurate, but that is a topic for another time.

The "design by complexity" argument posits that nature's complexity demands an intelligent designer. "This is too complex to have evolved, so God must have made it." But what if science can show how it could have evolved? "You lose all motivation to do any research once you declare that `this could only be the mark of a designer,'" says BYU biology professor Dr. Duane Jeffery. "You don't want further study to prove you wrong."

********
"They (Intelligent Design proponents) don't even understand evolution," says BYU's Keith Crandall. "The scientists they find are not biology researchers. They're not in the right field so they simply don't know the realities. They need to understand the arguments."

********
(This last quote is in the context of social and political issues.)
BYU's Jeffery worries that private parochial and home-schooling will increase because more people are unwilling to let their children be taught evolution. "How will those kids be able to participate meaningfully in the discourse that goes on in our society, and then cast responsible votes?"

There are several things here that I want to comment on, but will do so later.

Oh No, Not in Utah

Via The Panda's Thumb comes this article from the Salt Lake Tribune. Utah may be the next battle ground in the fight over including intelligent design in school ciricula.

But the moral-crusading group Eagle Forum, which has often flexed its muscle on Utah's Capitol Hill, argues a community has a right to teach its values to its children.

Sen. Chris Buttars, R-West Jordan, plans to lead the fight for instruction of divine design in Utah public schools. He wants to defuse some of the expected controversy by avoiding the term "creationism" altogether.

Instead, he favors "divine design," sometimes called "intelligent design," which "doesn't preach religion," he said. "The only people who will be upset about this are atheists."


I was afraid this day would come. I don't understand why Sen. Buttars thinks this is needed, when a good chunk of the kids in Utah attend relgion classes, oh about-- every day. Fortunately the U of U and BYU are committed to good science, which should help to deflect some of the scorn that could come Utah's way.

It's interesting--the Discovery Institute argues that intelligent design is not about religion. They have to or else they risk losing in the courts, just like "creation science" did. Yet people like Buttars make it about religion. The ID movement just might be destroyed (legally speaking) by its own supporters.

T. Rex Bone Indicates Gender and Relationship to Birds

Several months ago I briefly blogged about the discovery of a Tyrannosauraus rex bone that, when de-mineralized and rehydrated, appeared to have retained structures of soft tissue. The same authors (Mary Schweitzer, et al.) are back with another paper in Science which builds on the last one, with interesting results.

Reuters via MSNBC.com reports:

The bone tissue is strongly similar to that made inside the bones of female birds — and no other living type of animal — when they are producing the hard shells of eggs just before they lay them, said Mary Higby Schweitzer of North Carolina State University in Raleigh.

"In addition to demonstrating gender, it also links the reproductive physiology of dinosaurs to birds very closely. It indicates that dinosaurs produced and shelled their eggs much more like modern birds than like modern crocodiles," Schweitzer told reporters in a telephone briefing.

Female birds produce a layer of bone tissue called medullary bone when they are laying eggs. It is rich in calcium, providing minerals that would otherwise be leached from harder bone material, leaving the bird susceptible to fractures.



This image shows medullary bone (MB) and cortical bone (CB) of T. rex.

Since dinosaurs are thought to be the ancestors of birds, this finding makes sense and strengthens such an argument.

For more on dinosaurs and their relationship to birds, see this page at The Tree of Life web project, which is a pretty cool site--it's worth wandering around.

Creationists were unphased by the last paper--in fact they apparently saw it as evidence supporting young-earth creationism. (For more on this, see here.) It will be interesting to see how they spin this paper.

Blood, The Fall, and Intelligent Design

According to current LDS theology, blood is a distinctive part of mortal life. Although Adam and Eve had physical bodies in the Garden of Eden, their bodies did not contain blood. The Bible Dictionary states, "Before the fall, Adam and Eve had physical bodies but no blood" (see BD, "Fall of Adam"). Joseph Fielding Smith taught:

Continue Reading


Eating of that forbidden fruit subdued the power of the spirit and created blood in [Adam's] body. No blood was in his body before the fall. The blood became the life thereof. And the blood was not only the life thereof, but it had in it the seeds of death. (Seek Ye Earnestly, p.81)


That there was no blood before the fall is a relatively recent concept. From what I have been able to find, Joseph Fielding Smith appears to be the first person to have taught it. In regard to the origin and support for this teaching, Robert J. Matthews has written:
That there was no blood in the bodies of Adam and Eve before the Fall, and that blood came as a result of the Fall, is not categorically stated in any one passage of scripture, but leading doctrinal teachers such as President Joseph Fielding Smith and Elder Bruce R. McConkie have declared that such was the case. This conclusion is scripturally based and takes into account that blood is the mortal life of the body (see Gen 9:2-6; Lev. 17:10-15).

A further point supporting the conclusion that Adam and Eve had no blood in their premortal, non-death bodies is that we are assured by the Prophet Joseph Smith that resurrected beings do not have blood but possess bodies of flesh and bones "having spirit in their bodies, and not blood." The Prophet also said, "When our flesh is quickened by the Spirit, there will be no blood in this tabernacle." In speaking of the place where God dwells, the Prophet said, "Flesh and blood cannot go there; but flesh and bones, quickened by the Spirit of God, can." (See also 1 Cor. 15:50.)

This much we know about blood: (a) it is a vital part of our mortal lives and is basic to the reproductive process of mortals; (b) it was the agent of redemption in the atonement of Jesus Christ, he shedding his blood to redeem all people from the effects of the Fall and, upon the condition of repentance, from their personal sins; and (c) blood will not exist in the bodies of resurrected beings. With these known facts it becomes evident that blood is the badge of mortality, and since it will not exist in the deathless bodies of Adam, Eve, and their posterity in the resurrection, it is therefore reasonable to conclude that blood did not exist in the deathless, premortal bodies of Adam and Eve prior to the Fall. (Man Adam, p.45)
In passing, it should be noted that while blood is a vital part of our mortal bodies, and that of many animals, it is not a component of many mortal life-forms (plants, for example).

Blood fulfills a number of important roles in the body. It's most notable role is to deliver oxygen to cells and remove carbon dioxide waste. It also facilitates the transportation of many substances through the body including nutrients, hormones, and components of the immune system. Because it is so vital to life, there are mechanisms in place that help to keep us from losing blood, ie. clotting.

The formation and regulation of clotting involves a number of proteins, all of which are encoded in our genes. Inherited deficiencies in these genes can lead to such conditions as hemophilia. It is beyond the scope of this post to detail the interactions of these proteins, such as in the clotting cascade. (See here for further reading.) It is sufficient to know that the regulation of clotting is complicated and impressive.

Elder Russell M. Nelson has commented several times on the wonders of the human body, including the ability of blood to clot. (See, for example, “The Magnificence of Man,” Ensign, Jan. 1988, 64.) The regulation of clotting has also been discussed by Michael Behe in his book, Darwin's Black Box. In his book Behe claims that the clotting cascade is an irreducibly complex (IC) system, which means that if any component of it were removed, the system would fail. Since it is highly improbable, if not impossible, that the whole system could have been fully developed by natural means, all at once, and since the system would not confer any advantage to an organism if it was developed one component at a time, Behe argues that this system has been intelligiently designed. Presumably, the "designer" is God. If Behe is correct, his argument would seem to add scientific support to the sentiments of Elder Nelson, and some undoubtably see it as such. (Whether or not Behe is correct is beyond the scope of this post.)

In thinking about the Fall, a natural question arises: Why was it necessary? Why did God create things in a paradisiacal state rather than a mortal state? In his criticism of evolution, Joseph Fielding McConkie wrote:
Latter-day Saint theology recognizes God as the creator. Thus the labor of creation must be godlike. God does not do shoddy work. Having completed the work of creation, he declared it "very good" (Moses 2:31). (Answers: Straightforward Answers to Tough Gospel Questions, p. 158-162.)
While the scriptures have much to say concerning the consequences of (and redemption from) the Fall, they have little to say about the reason for the Fall. Robert J. Matthews expressed this opinion:
If God had created man mortal, then death, sin, and all the circumstances of mortality would be God's doing and would be eternal and permanent in their nature whereas if man brings the Fall upon himself, he is the responsible moral agent, and God is able to rescue and redeem him from his fallen state. (Bible! a Bible!, p. 187)

Apparently McConkie sees anything less than a paradisiacal creation as "shoddy" and ungodlike. Matthews sees the Fall as a way for God to avoid responsibility for our mortal condition.

There may be other explanations, but I do not find either of these explanations compelling, which leads to the point of this post: If God does not create anything "shoddy" (and therefore ungodlike) and has no responsibility for mortal conditions, how can we say that God designed or created blood, the hallmark of the Fall? We can widen the question to include all things that are in a fallen condition, since the scriptures state that all things testify of Christ. In fact it was God who issued the curses that would characterize mortality for Adam and Eve. If we take the scriptural account literally, thorns and thistles were apparently previously unknown to earth. This means that either God had previously created such plants but held them in a dormant state, or he created them when Adam and Eve fell. The same can be said for blood or any other biological characteristic of mortality.

If we are to exclude any role for evolution in the creation of life on this earth on the grounds that God either does not create, or cannot be responsible for, anything that is less than perfect, then it seems to me that we have to relinquish his role in the creation of anything that characterizes fallen conditions, including blood. Conversely, if God has created (in a direct way) aspects of our mortal condition, then we cannot say that using evolution in the creative process would be "shoddy" and ungodlike. If evolution is to be rejected as a tool which God uses to create, it will have to be on theological grounds other than its imperfect nature.

Andromeda

This news story from National Geographic says that the nearest galaxy, Andromeda, is three times larger than previously thought.

I don't know how significant that is--mostly I just wanted an excuse to post the pretty picture below. Also, I know from personal experience that with a simple pair of binoculars you can see Andromeda. You just need to know where to look. It kind of looks like a faint whispy cotton ball. I wonder if anybody over there is looking at us.

Dept. of HHS Asks PNAS Not to Publish Paper

Science news reports:

In an unprecedented move, officials at the Department of Health and Human Services (HHS) asked the Proceedings of the National Academy of Sciences (PNAS) to pull a bioterrorism-related paper that the journal planned to publish online on 30 May. The journal took the paper off its publication schedule on 27 May and has been reviewing it internally.

The paper, by mathematician Lawrence Wein of Stanford University and graduate student Yifan Lu, models how bioterrorists could wreak havoc by slipping a small amount of botulinum toxin into the U.S. milk supply, and it spells out interventions that the government and the dairy industry could take to prevent this nightmare scenario.


Apparently the government objects to some of the details contained in the paper. This is one of those tough science/law/national defence issues--when should scientific findings NOT be published? Apparently Wien wrote and Op-Ed in the New York Times that describes his paper. PNAS could go ahead and publish the paper, scrap it, or modify it. It will be interesting to see how this turns out.
