What Could Be More Scary than the Flying Spaghetti Monster?

 
From the BBC News: Church removes 'scary crucifix'.

A large sculpture of Christ on the cross has been removed from outside a church in West Sussex after its vicar said it was "scaring young children".

The Reverend Ewen Souter said the 10ft crucifix was "a horrifying depiction of pain and suffering" which was also "putting people off".

The sculpture, located at the side of St John's Church in Broadbridge Heath, has now been given to Horsham Museum.

It will be replaced with a new stainless steel cross.

Stainless steel crosses are also pretty scary.

Africans Need Jesus?

 
From RichardDawkins.net: Matthew Parris: As an atheist, I truly believe Africa needs God.

Now a confirmed atheist, I've become convinced of the enormous contribution that Christian evangelism makes in Africa: sharply distinct from the work of secular NGOs, government projects and international aid efforts. These alone will not do. Education and training alone will not do. In Africa Christianity changes people's hearts. It brings a spiritual transformation. The rebirth is real. The change is good.

Read the comments. Some people aren't convinced that Christianity is the only way to change people's hearts for the better. Some people think it might be a wee bit condescending to imply that rationalism might be fine among Caucasians but Africans need superstition.

Changing Your Mind About Evolutionary Psychology

 
Every year John Brockman collects essay from his friends (I want to be one) and published them on his website and in a little book [The Edge Annual Question - 2009].

This year's question was, "What game-changing scientific ideas and developments do you expect to live to see?" Last year's question was, "What Have You Changed Your Mind About? Why?" The book is now out.

There are far too many answers to these questions. I usually look at a few of them but it soon becomes boring.

Sharon Begley feels the same way but she has picked out a few interesting mind changes from the 2008 question. She writes in the Jan. 3, 2009 issue of Newsweek [On Second Thought ...].

The most fascinating backpedaling is by scientists who have long pushed evolutionary psychology. This field holds that we all carry genes that led to reproductive success in the Stone Age, and that as a result men are genetically driven to be promiscuous and women to be coy, that men have a biological disposition to rape and to kill mates who cheat on them, and that every human behavior is "adaptive"—that is, helpful to reproduction. But as Harvard biologist Marc Hauser now concedes, evidence is "sorely missing" that language, morals and many other human behaviors exist because they help us mate and reproduce. And Steven Pinker, one of evo-psych's most prominent popularizers, now admits that many human genes are changing more quickly than anyone imagined. If genes that affect brain function and therefore behavior are also evolving quickly, then we do not have the Stone Age brains that evo-psych supposes, and the field "may have to reconsider the simplifying assumption that biological evolution was pretty much over" 50,000 years ago, Pinker says. How has the view that reproduction is all, and that humans are just cavemen with better haircuts, hung on so long? "Even in science," says neuroscientist Roger Bingham of the University of California, San Diego, "a seductive story will sometimes … outpace the data." And withstand it, too.

There are many reasons for changing your mind about the validity of evolutionary psychology but the idea that "human genes are changing more quickly than anyone imagined" isn't one of them.

As you might have guessed, John Hawks is really happy to encourage that kind of thinking. Hawks is a proponent of the idea that genes can be fixed in the entire human population by natural selection in only a few thousand years [Recent evolution in Newsweek].

I wish Canadian politicians would be as rational as Carter and appreciate that this is a complex situation where nobody is totally right.

The one thing we can be sure about is that war is wrong.¹

Testing Natural Selection: Part 2

 
There are several interesting articles about evolution in the Januray 2009 issue of Scientific American. One of the most interesting is an article by H. Allen Orr of the University of Rochester (NY, USA). The magazine title is "Testing Natural Selection"¹ and, as the title implies, the focus is on evolution by natural selection.

Orr's article gives us an opportunity to compare and contrast the views of an adaptationist (Orr) and a pluralistic approach to evolution.

In Testing Natural Selection: Part 1 we discussed two of Orr's opinions: (1) random genetic drift is not as common as most people think, and (2) most (if not all) visible phenotypic change is driven by natural selection.

Here, we discuss Orr's ideas about speciation.

When we say "speciation" we're talking about the biological species concept. Speciation occurs when two formerly compatible populations evolve to the point at which they can no longer interbreed. The key question is what causes this reproductive isolation and how does it evolve?

To contemporary biologists, then, the question of whether natural selection drives the origin of species reduces to the question of whether natural selection drives the origin of reproductive isolation.

For much of the 20th century, many evolutionists thought the answer was no. Instead they believed that genetic drift was the critical factor in speciation. One of the most intriguing findings from recent research on the origin of species is that the genetic drift hypothesis about the origin of species is probably wrong. Rather natural selection plays a major role in speciation.

Orr is correct to point out that random genetic drift is important in speciation. It's the mechanism described in many evolutionary biology textbooks, though it's not the mechanism that most people think about when they think about speciation.

Many biologists have always believed that natural selection plays a much more important role in speciation than random genetic drift. They aren't happy with the textbook description. Orr is one of these biologists. He now claims that the drift explanation is "probably wrong."

Let's think about what has to happen when two species become reproductively isolated. We'll use allopatric speciation as an example.²

We begin with a situation where two populations (races, subspecies) are geographically separated. There is very little gene flow between them so they evolve independently of each other. Over time, they may come to be different because each is adapting to different environments or they may just drift apart by accident. With respect to the actual speciation event, these differences don't matter.

From time to time, individuals from the two subspecies will interbreed to produce fertile offspring. This is responsible for limited gene flow between the subspecies and it proves that speciation has not occurred. If the barrier between the two populations breaks down they will merge back into a single population.

But if the two species have been separated for a long period of time, mutations that prevent interbreeding will accumulate and hybrids will become less and less viable until eventually no fertile hybrids are produced and speciation is complete. There are many ways that this can happen but a common hypothesis involves the build-up of post-zygotic genetic incompatibilities called Dobzhansky-Muller (D-M) incompatibilities.

How are D-M incompatibilites fixed in the population? If they interfere with the matings of individuals from the two populations then how come they don't contribute to infertility when individuals from the same population mate with each other? When the mutation first arises it seems to have a very strange property. It doesn't affect matings between an individual carrying the D-M allele and an individual not carrying that allele from the same population but it does affect matings between the individual carrying the new D-M allele and and an individual from the other population.

In order for this to happen there must already be some genetic differences between the two populations in terms of mating and reproduction. Those differences have accumulated in each of the populations but they must not have an effect on hybrid crosses. Presumably, the new D-M allele is not harmful in one genetic background but it is in the other.

Are these pre-existing potentiators neutral within a population, in which case they become fixed by random genetic drift? Or, are they beneficial in one of the populations, and not in the other, in which case they are fixed by natural selection? The general consensus has been that they are neutral within a population and they accumulate by accident. When enough of them become fixed the cumulative effect is to prevent hybridization. The last allele to arise, the D-M incompatibility allele, is the straw that breaks the camel's back.

Orr believes that the alleles are beneficial in one of the populations. Thus, according to him, reproductive isolation is driven by natural selection. He gives two examples.

The first one is the incomplete speciation in monkeyflower subspecies. I described this in an earlier posting [Speciation in Monkeyflowers], where I pointed out that the role of natural selection was not clear. The differences in flower color and pollinators could have arisen by selection if one postulates changes in the bee population but they could also be due to chance.

For an adaptationist like Allen Orr there's no doubt about what happened.

A good example is the evolutionary history of the two monkeyflower species mentioned earlier. Because their pollinators seldom visit the “wrong” species of monkeyflower, the two species are almost completely isolated reproductively. Even though both species sometimes occur in the same locations in North America, a bumblebee that visits M. lewisii almost never visits M. cardinalis, and a hummingbird that visits M. cardinalis almost never visits M. lewisii. Thus, pollen is rarely transferred between the two species. In fact, Schemske and his colleagues showed that pollinator differences alone account for 98 percent of the total blockage in gene flow between the two species. In this case, then, there can be no doubt that natural selection shaped the plants’ adaptations to distinct pollinators and gave rise to strong reproductive isolation.

This is not a good example of speciation by natural selection. We simply don't know if the flower color mutation spread in one of the populations because it conferred a selective advantage on individuals within that population.

Besides, these two "species" will still form viable hybrids so they're not really species in the first place.

The other example of presumed speciation by natural selection comes from studies on Drosophila There are several example of D-M incompatibility alleles that have been identified. In some of them, there is evidence at the sequence level for rapid fixation. If correct, this is a good indication that the alleles have become fixed by natural selection. The resulting reproductive isolation is an epiphenomenon.³

One example is OdsH in Drosophila mauritiana. It appears to result in an increase in sperm production so it may have been selected in the early population of this species, before it became a species. Presumably, the allele was beneficial in the genetic background that had evolved up to that point and presumably it was detrimental in the genetic background of whatever subspecies it was related to.

The genetic background is obviously part of the speciation event. I suppose that if even one of the D-M alleles is selected then it's fair to say that speciation by natural selection took place.

The question is whether this is common or not. Shucker et al. (2005) looked at post-zygotic reproduction isolation in two populations of grasshopper and provided evidence that all the D-M incompatibilities could be adequately explained by random genetic drift. We'll need to have many more examples in order to decide whether natural selection explains most speciation events.

Personally, I find it easier to understand how reproductive isolation could arise by accidental accumulation of many neutral alleles that eventually lead to reproductive isolation. It's harder to envisage alleles that confer a selective advantage within one population but are extremely detrimental in the other.

Orr doesn't agree.

The studies of the monkeyflower and of hybrid sterility in fruit flies only begin to scratch the surface of a large and growing literature that reveals the hand of natural selection in speciation. Indeed, most biologists now agree that natural selection is the key evolutionary force that drives not only evolutionary change within species but also the origin of new species. Although some laypeople continue to question the cogency or adequacy of natural selection, its status among evolutionary biologists in the past few decades has, perhaps ironically, only grown more secure.

I'm not an expert on speciation and I don't hang out with people who work in the field. However, my general impression from reading the scientific literature is that Orr's statements may be somewhat exaggerated. From what I can see, there are a great many evolutionary biologists who question the hegemony of natural selection. Their numbers seem to be growing, not shrinking.

I don't know where Orr is coming from when he implies that laypeople question the adequacy of natural selection. In my experience laypeople only think about natural selection. They have no idea that there are any other mechanisms of evolution.

2. In allopatric speciation the two diverging populations are geographically separated. That's what makes them distinct populations. In sympatric speciation the two populations may exist in the same geographical and restricted gene flow between them is due to other factors. It's easier to visualize what's happening during allopatric speciation but the logic can apply to sympatric speciation as well.

3. I don't think Orr is actually proposing that there would be selection for reproductive isolation. How would that work?

Nobel Laureate: Elias Corey

 

The Nobel Prize in Chemistry 1990.

"for his development of the theory and methodology of organic synthesis"



Elias James Corey (1928 - ) was awarded the Nobel Prize for his contributions to the synthesis of organic molecules. Here's the Press Release describing his achievements.

Prize for masterly development of organic synthesis

The development of the art of organic synthesis during little over a hundred years has afforded efficient methods of manufacturing products such as plastics and other artificial fibres, paints and dyes, biocides and pharmaceutical products, all of which have contributed to the high standards of living and health, and the longevity, enjoyed at least in the Western world.

This year's Nobel Prize in Chemistry has been awarded to Professor Elias J. Corey, USA, for his important contributions to synthetic organic chemistry. He has developed theories and methods that have made it possible to produce a large variety of biologically highly active, complicated natural products, thereby making, among other things, certain pharmaceuticals commercially available. Corey's work has also led to new general methods of producing, synthesising, compounds in simpler ways.

The background to Elias J. Corey's successes lies in the fact that he has in a strictly logical way developed the principles of what is termed retrosynthetic analysis. This involves starting from the planned structure of the molecule one wishes to produce, the target molecule, and analysing what bonds must be broken, thus simplifying the structure step by step. One then finds that certain fragments are already known and their structure and synthesis already described. After working backwards in this way from the complex to the already known, it is possible to start building, synthesising, the molecule. This method has proved very amenable to data processing, which has entailed rapid developments in synthesis planning. Combining this synthesis planning with singular creativity, Corey has developed new methods of synthesis. He has produced some hundred important natural products, for example the active substance in an extract from the ginkgo tree, used in folk medicine in China.

Background information

Organic synthesis, that is, the production of complicated organic compounds using simple and cheap starting material, is one of the prerequisites of our civilisation. It is understandable that contributions in this field have often been rewarded with the Nobel Prize in Chemistry. Thus in 1902, only the second year that Nobel Prizes were awarded, the Chemistry Prize went to Emil Fischer for his work on synthesis within sugar and purine chemistry. In 1905 Adolf von Baeyer received the prize in recognition of contributions to the development of the chemical industry through his work on organic dyestuffs. Otto Wallach received the 1910 Prize for contributions to the development of the chemical industry. The 1912 prize went to Victor Grignard for his development of organic magnesium compounds, also termed Grignard reagents, into important intermediates in organic synthesis. In 1950 Otto Diels and Kurt Alder shared the Nobel Prize for discovering the preparatively very useful diene synthesis. Robert B. Woodward received the 1965 prize for his brilliant contributions to the development of the art of organic synthesis. In 1979 Herbert C. Brown and Georg Wittig were rewarded for developing boron compounds and phosphorus compounds, respectively, into important reagents in organic synthesis.

The synthesis of complicated organic compounds often shows elements of artistic creation, as for example architecture. Many earlier syntheses were performed more or less intuitively, so that their planning was difficult to perceive. Asking a chemist how he came upon precisely the starting materials and reactions that so elegantly led to the desired result would probably be as meaningless as asking Picasso why he painted as he did. The process of synthetic planning has been likened to a game of three-dimensional chess using 40 pieces on each side. But the problem may be even harder than this. Over 35,000 usable methods of synthesis are described in chemical literature, each with its possibilities and its limitations. During the synthesis, moreover, new methods appear which can modify the strategy.

Beginning in the 1960's, Corey coined the term, and developed the concept of, retrosynthetic analysis. Starting from the structure of the molecule he was to produce, the target molecule, he established rules for how it should be dissected into smaller parts, and what strategic bonds should be broken. In this way, less complicated building blocks were obtained, which could later be assembled in the process of synthesis. These building blocks were then analysed in the same way until simple compounds had been reached, whose synthesis was already described in the literature, or which are commercially available. Corey showed that strictly logical retrosynthetic analysis was amenable to computer programming. At present, synthesis planning with the help of computers is developing rapidly.

Through his brilliant analysis of the theory of organic synthesis, Corey has contributed in high degree to his own and other researchers' being able, during the last few decades, to complete total syntheses, hitherto impossible, of complicated, naturally-occurring, biologically active compounds, according to simple logical principles.


Elias J. Corey has himself synthesised about a hundred important natural products, of which only a few will be mentioned here. In 1978 he produced gibberellic acid (1), which belongs to a class of very important plant hormones of complicated structure. Recently, he has also synthesised (+)-ginkgolid (2), which owing to its complicated structure is a formidable challenge to anyone working in synthetic chemistry. (+)-ginkgolid is the active substance in an extract from the ginkgo tree, used as a folk medicine in China. The sales value of this natural product is believed to amount to $500 million annually. It is used in treatment of blood circulation disturbances in the elderly, and in asthma. Corey's most important total syntheses concern the medically very important eicosanoids such as prostaglandins, prostacyclins, thromboxanes and leucotrienes, which occur naturally in extremely small quantities. These frequently very unstable compounds answer for multifarious and vital regulatory functions of significance for reproduction, blood coagulation, normal and pathological processes in the immune system, etc. Their importance is witnessed by the award of the 1982 Nobel Prize in Physiology or Medicine to Sune Bergstrom, Bengt Samuelsson and Sir John Vane for the discovery of prostaglandins and closely related biologically active substances. Corey has with enormous skill carried out structural determination and total syntheses of a large number of compounds of many different types of eicosanoids such as prostaglandins and leucotrienes such as lipoxin A (3). It is thanks to Corey's contributions that many of these important pharmaceuticals are commercially available.

To perform the total syntheses successfully, Corey was also obliged to develop some fifty entirely new or considerably improved synthesis reactions or reagents. It is probable that no other chemist has developed such a comprehensive and varied assortment of methods which, often showing the simplicity of genius, have become commonplace in the synthesising laboratory. His systematic use of different types of organometallic reagent has revolutionised recent techniques of synthesis in many respects. He has also in recent years introduced a number of very effective enzyme-like catalysts. These chiral catalysts give only one mirror isomer of the target product, in certain types of synthetically important reaction. The chiral catalysts are simple and easy to recover, and can in some cases be used in their own production.

Democracy and Lawyers

 
In Canada we vote by marking a "X" on the ballot and putting it in a box. The person with the most "X's" wins.

If the vote is close, we count the ballots again and declare a winner.

It doesn't work that way in America as we learned in 2000. It took several truckloads of lawyers and many judges to count the ballots in Florida. Ultimately it was the US Supreme Court who decided that George Bush would be President.

Now they're doing it again, only this time it's a Senate race in Minnesota [Funny Business in Minnesota]. The lawyers and the judges will decide who actually won. Meanwhile, politicians in Washington will fight over which candidate they will put into the Senate while the court cases are being decided. Apparently the Senate doesn't have to accept the recount as long as the loser is unhappy.

This must be why they call America "the greatest democracy on Earth." It's because America has so many lawyers.

Probably?

 
In Britain there are 800 buses with the sign, "There’s probably no God. Now stop worrying and enjoy your life." [Atheists Send a Message, on 800 Buses]

Apparently the British atheists wanted to leave out the word "probably" but that wouldn't conform to British advertising guidelines. I wonder if the guidelines apply across the board?

Are there bus and billboard signs that say, "Jesus probably loves you?"

Has the British anthem been changed to, "God probably saves the Queen?"

And what about the coins? Will they be changed to read, "Queen, probably by the grace of God" (D.P.G.) in order to conform to advertising standards?

The best remark comes from an American tourist who spotted the sign on a bus. America is the bastion of free speech (according to some Americans) but only if it's speech that doesn't offend.

Spotting one of the buses on display at a news conference in Kensington, passers-by were struck by the unusual message.

Not always positively. "I think it’s dreadful," said Sandra Lafaire, 76, a tourist from Los Angeles, who said she believed in God and still enjoyed her life, thank you very much. "Everyone is entitled to their opinion, but I don’t like it in my face."
