Polio Eradication Proves Difficult

There is an story today in the New York Times about the uphill battle to eradicate polio from the earth.

Nearly 18 years ago, in what they described as a "gift from the 20th century to the 21st," public health officials and volunteers around the world committed themselves to eliminating polio from the planet by the year 2000.

Since then, some two billion children have been vaccinated, cutting incidence of the disease more than 99 percent and saving some five million from paralysis or death, the World Health Organization estimates.

But six years past the deadline, even optimists warn that total eradication is far from assured. The drive against polio threatens to become a costly display of all that can conspire against even the most ambitious efforts to eliminate a disease: cultural suspicions, logistical nightmares, competition for resources from many other afflictions, and simple exhaustion. So monumental is the challenge, in fact, that only one disease has ever been eradicated — smallpox. As the polio campaign has shown, even the miracle of discovering a vaccine is not enough.

Not least among the obstacles is that many poor countries that eliminated polio have let their vaccination efforts slide, making the immunity covering much of the world extremely fragile, polio experts warn. They compare it to a vast, tinder-dry forest: if even one tree is still burning, a single cinder can drift downwind and start a fire virtually anywhere.
The article focuses on problems in Nigeria and India. It's worth reading and will hopefully, at the least, renew your sense of graditude for modern medicine/science.

Other posts I have, which are not of this Blog

For those who read this blog, but do not keep tabs on the broader LDS blogging community (the bloggernacle), I thought I would point out some other posts I've done elsewhere.

First is a post I was invited to contribute to By Common Consent, Race: a scientific primer.

Then of course there is Mormons and Evolution. It is a group blog that I contribute to, but the pace is much slower than most other blogs. This is because we wanted to collect substantive posts--not daily "hey, check this out" kind of stuff. Jeff came up with this concept of a "Reconciliation Notebook" which is basically a collection and summary of our individual posts. My notebook is here. Some of my more recent posts have been about the Fall, two letters Joseph F. Smith published in 1911, and some background on the 1909 Origin of Man statement. I did not cross-post them here, so go read them if you are interested.

Smelling a Turkey

A story about a family in Turkey is getting some play--the kids have a genetic mutation that has affected their brain development such that they do not walk upright but bear crawl instead. Although this is interesting on its own terms, the publicity has been increased by talk of their behavior as being an evolutionary "throwback" and a forthcoming BBC documentary.

Anthropologist John Hawks has a lengthy and skeptical post that urges caution. Some highlights:

It is not a hoax. It is a BBC publicity blitz. And to me, it seems like a stunningly cynical PR blitz. In other words, we're being played.

--------------------

The cynical part is that the entire progression of the story was predictable without any necessity of orchestrating it. You see, it has all happened before, with almost exactly the same sequence of events. It is the Flores story reborn.

Consider: a rare, unique, and strange discovery comes to light. Immediately many experts are skeptical, but it takes time for them to organize a response. In the interim, a few strong backers explain that unique evolutionary principles can explain the find, and some experts cautiously agree. Then, two things happen: first, there is a conflict between the Western backers of the find and a senior local scientist; second, a high-profile documentary appears in which the discoverers can take their case directly to the public.

It's an autocircus.

-------------------

The main point is this: the fact that a gene breaks something doesn't mean that it was the key gene necessary to create something.

Go read his post if you are interested. For my part, I'll just say that it is unfortunate--years from now critics of evolution will say, "Oh yeah, and remember when scientists thought that family in Turkey was like the missing link?"

Noah: Ice, Ice, Baby

Some time ago, while reading Duane Jeffery's article on Noah's flood (pdf) I noticed in note #6 a reference to a Nature paper describing Antarctic ice cores dating back 750,000 years. How would a global flood affect such ice cores?

For the young earth creationists (YECs) at Answers in Genesis there is no problem because they claim the ice age that formed the polar ice occured after the flood. According to them, whether one views the ice at the bottom of the cores as compressed seasonal layers or lots of ice formed in a short amount of time is all about what assumptions you start with.

Over at the American Science Affiliation* there is an article frankly titled, The GISP2 Ice Core: Ultimate Proof that Noah’s Flood Was Not Global (pdf), which reviews how ice cores are studied, their implication for Noah's flood, and responds to YEC arguments.

NASA has a great website describing paleoclimatology where various methods of studying ancient climates are clearly explained (including ice cores) accompanied by beautiful pictures. It looks like the site isn't quite complete, so you'll want to check back in the future. Also note that some of the topics have a second page that is easy to miss.


Finally I'll just note that in the Nature paper, the temperature fluctuations inferred from sediment cores (c) look to me like they match those of the Antarctic ice cores (b) very well. Something to keep in mind when confronting the argument that the fluctuations measured at the bottom of ice cores could reflect short-term (even daily) fluctuations.




* ASA describes itself as "a fellowship of men and women in science and disciplines that relate to science who share a common fidelity to the Word of God and a commitment to integrity in the practice of science."

Update: Western Geologist has additional commments on ice cores. Also, I forgot to mention that a couple of years ago there was discussion of ice cores in the FARMS Journal of Book of Mormon Studies.

Trent Stephens on Evolution

FAIR has posted the transcript of a presentation Trent Stephens made at the 2003 FAIR conference. It is basically a highly condensed version of the book he co-authored, Evolution and Mormonism. I'll highlight just a couple of things here.

He says:

Now the official position can be obtained in a number of ways. When Jeff [Meldrum] and I, and Forrest Peterson who was a student who worked with us on this project, first began writing our book a few years ago we went to my bishop and then to our stake president and obtained permission for the bishop to write to the First Presidency to obtain the official statement of the Church. They then sent us a cover letter and a xeroxed copy of the section on evolution in the Encyclopedia of Mormonism.
Their book was a little confusing on whether they received the EofM article from the First Presidency. While chapter two of their book does not specifically mention receiving the article, page 56 suggests that they did--so I'm glad to have that clarified.

Also, 2 Nephi 2:22 has recently been brought up elsewhere in the bloggernacle, and you can read Stephens' take on it in the transcript.

The Creationists Follow-Up: Walter Lammerts

In my last post on The Creationists, a commenter (Western Geologist) mentioned an episode concerning Walter Lammerts visiting Chief Mountain. I read that section again and thought I would elaborate on it.

Continue Reading


Lammerts, along with Henry Morris and others, was one of the founders of the Creation Research Society. He had very strict views on evolution.

At a time when the strictest creationists were allowing for microevolution and the natural development of some species, he held out for "the absolute fixity of species."

Morris and Whitcomb's 1961 The Genesis Flood cited Lammerts several times and contained pictures he had taken at Glacier National Park to illustrate the Lewis overthrust.

Lammerts wanted to explore the area with someone with training in geology. In 1962 he did so with two Seventh-day Adventists, Richard Ritland and P. Edgar Hare. Both had strayed from strict "flood geology" in the course of their education and ascribed little geological significance to Noah's flood. In the case of Hare, the Seventh-day Adventist Church sponsored him to obtain a doctorate in geochemistry at the California Institute of Technology.
While there he began developing a dating method based on changes in the ratios of amino acids in ancient shells, which he at first hoped would yield relatively recent ages. However, as he informed a church official, his methods gave dates virtually identical to those obtained from radiocarbon data--and as high as thirty-five thousand to forty thousand years. "Is it just a coincidence that this came out this way?" he asked suggestively.

The three hiked to view the contact line between the Precambrian and Cretaceous strata.
To Ritland and Hare, the evidence of overthrusting, especially signs of grooving and scouring , was "overwhelmingly clear." Lammerts, though appreciative of his young companions' scientific approach to the problem, found himself more confused than convinced. He thought it especially puzzling that Ritland and Hare seemed "so anxious to prove that Price was wrong and that this wrong order formation was really the result of overthrusting." As he descended the mountain, Lammerts appeared "badly shaken." Not only had he just gone on record in The Genesis Flood as discounting the evidence for overthrusting, but, as Ritland and Hare pointed out, the supporting photographs he had given Whitcomb and Morris were of rocks two hundred feet above the contact line.

Although the experience contradicted an article Lammerts had in press at Christianity Today,
he eventually decided there was sufficient ambiguity to justify publishing what he had originally written. This decision "badly disillusioned" Ritland, who felt further chagrined when he read Lammerts's description of him in the article as a Harvard-trained Ph.D. who agreed with Price that "most" of the sedimentary rocks had resulted from Noah's flood.

You can view a slideshow on the formation of the Lewis overthrust here. (Look through all of the slides--they're interesting).

Book Review: The Creationists

In 1931 the First Presidency issued a statement to all General Authorities stating that the Church had no doctrine concerning the existence of pre-Adamites. Although it may seem strange, in addition to the direct involvement of B.H. Roberts, Joseph Fielding Smith, and James E. Talmage was the indirect involvement of a Seventh-day Adventist: George McCready Price. Price was an amateur geologist who sought to reconcile the Bible and the teachings of Ellen G. White with science.

The result of this effort, explained in The New Geology and other works, came to be known as 'flood geology,' a concept that sought to explain all of the fossil strata as a result a global Noachian flood. Price's publications influenced--or at least gave support to--Joseph Fielding Smith's views of earth history and Smith invoked Price's writings in the 1931 controversy. James Talmage, on the other hand, had no patience for Price's arguments. Although the controversy was halted by the First Presidency statement, Price's influence on Joseph Fielding Smith continued. In his later book Man, His Origin and Destiny, Joseph Fielding Smith referenced or recommended two of Price's books.

Although this slice of history is of particular interest to Mormons, Price had a much larger influence on fundamentalism and creationism that can still be seen today. The story of the creationist movement is the subject of historian Ronald L. Numbers' book, The Creationists. If you want to understand the history of the creationist movement--and to some extent the newer intelligent design movement--this is the book to read.

Continue Reading


Numbers was born and raised as a Seventh-day Adventist and instructed in strict George McCready Price-style teachings. He later abandoned the instruction of his youth.

I vividly remember the evening I attended an illustrated lecture on the famous sequence of fossil forests in Yellowstone National Park and then stayed up much of the night with a biologist friend of like mind...first agonizing over, then finally accepting, the disturbing likelihood that the earth was at least thirty thousand years old.
Although now estranged from his Adventist roots and its creationist teachings, Numbers seeks to treat the topic and its adherents (which included his own father) with respect.

There are several catagories of creationism with shades between them. So-called young earth creationism (YEC) is the strictest form and established itself as synonymous with 'flood geology,' and 'scientific creationism' or 'creation science.'

By the late nineteenth century even the most conservative Christian apologists readily conceded that the Bible allowed for an ancient earth and pre-Edenic life. With few exceptions, they accommodated the findings of historical geology either by interpreting the days of Genesis 1 to represent vast ages in the history of the earth (the so-called day-age theory) or by separating a creation "in the beginning" from a much later Edenic creation in six literal days (the gap theory). Either way, they could defend the accuracy of the Bible while simultaneously embracing the latest geological and paleontological discoveries...

The creation scientists, by contrast, compress the history of life on earth into less than ten thousand years. To accomplish this, they attribute most of the fossil record to the brief period of the flood and its aftermath. They believe that the majority of plants and animals buried sequentially in the stratified rocks once lived together in the antediluvian world.


As alluded to above, 'creation science' has its roots in George McCready Price. Price's development of 'flood geology' was a way to not only reconcile scripture and geology, but to also cut off evolution at its base, since evolutionary theory depended on the orderly sequence of the fossil record to be able to infer biological change over time (radiometric dating had not yet been developed). Price sought out geological anomalies such as the Lewis Overthrust where fossils appeared out of order to argue that there was no real order to the fossil record, and therefore no way to infer biological change over time. He was mostly ignored by the geology community--and even by his own church--but he attracted a following, though some associates broke with him on several issues. His concepts were re-packaged in the 1960's by John Whitcomb and Henry Morris (who passed away a few days ago) in their book, The Genesis Flood, which helped launch the modern YEC movement.

Henry Morris went on to help form the Creation Research Society (CRS)--the first strict creationist society to survive long-term (others had dissolved in bickering) and later the Institute for Creation Research (ICR). A number of these leading creationists held Ph.D. degrees in subjects like engineering, physics, and biology, yet until 1969 'flood geology' did not have any doctoral geologist supporters. In a repeated scenario, creationist geology doctoral students eventually came to disbelieve in the central tenets of 'flood geology.' Since then the movement (including several different organizations such as Answers in Genesis) has gained a number of scientifically trained people from a variety of fields, although their contribution to 'creation science' has often consisted largely of arm-chair speculation and library research devoted to finding weaknesses in opponents' work. What they lack in genuine scientific evidence they make up for in confidence and argumentation.

Numbers does not seek to refute creationist claims, but as a matter of historical record he does document disagreements and sloppy research. For example the famous Paluxey footprints were touted in The Genesis Flood as showing that humans and dinosaurs co-existed because they each left prints in the same rock formation. However the original claim came from Clifford Burdick, a man who possesed zeal but was ultimately untrustworthy and sensationalistic. Even though the footprint claim was eventually retracted by Henry Morris, it can still be found in creationist literature.

Because the book covers creationism from the late nineteenth century on, it can be boring as the details of the struggles of long-dead figures are presented, although it is remarkable how little the basic arguments surrounding reconciliation of science with scriptures have changed. The book begins to pick up when discussing George McCready Price and gets even more interesting with the story of how the more science-friendly Christian organization, American Science Affiliation (ASA), helped to spark a fundamentalist backlash. The later chapters deal with more modern creationists like Henry and John Morris, Duane Gish, and others, as well as some of the major court battles. Although Ken Ham is mentioned, the book pre-dates the formation of Answers in Genesis. Also, a portion of a chapter describes creationism in the LDS context and centers on the 1931 controversy, the publication of Man, His Origin and Destiny, and the creationist writings of Melvin Cook.

Why has YEC creation science become so popular? Numbers suggests that it is because it allows one to read the Bible without gymnastics. As explained above, very conservative Christians have reconciled scripture and geology using the day-age and gap theories, but creation science eliminates the need for such additional assumptions--the scriptures can be read and understood at face value. This straightforward accuracy, its proponents argue, invites confidence in all of scripture, including that portion dealing with future prophesied events. My own thought is that while many Christians do not accept strict creationist teachings in a systematic way, some appreciate them for the balance they represent against mainstream science.

Although such results may seem desirable at first glance, such an approach to scripture seems problematic in the LDS context. The Creationists provides perspective and understanding of this religious movement and challenges us to consider where we should stand on similar issues.
