The Casey Luskin Lesson Plan on Teaching the Controversy

 
I often criticize the Intelligent Design Creationists for not coming up with anything other than criticism of evolution. That criticism is perfectly justified as we can see in Casey Luskin's latest posting on Evolution News & Views: Back to School Lesson Plans That Actually Help Students Understand Evolution. He's even gone as far as proposing a lesson plan on evolution for grades 4-7. One of the important parts of that lesson plan is the challenges to evolution.

It's Monday, and it's Thanksgiving Day in Canada, so I'm taking a bit of a break. Let's have some fun with Luskin's lesson plan. I'll quote each of his points with a brief response.

Step 3: Learn About the Case against Evolution (1.5 hours). Now students will learn about some of the science that challenges evolution. Watch the DVD Icons of Evolution.
- Ask students to explain the difference between microevolution and macroevolution.

This is far too complicated for public school students. The simple answer is that microevolution describes changes occurring within populations and macroevolution describes the history of life. Macroevolution includes things such as speciation that are not part of microevolution and it also includes things like asteroid impacts, ice ages, and drifting continents in order to explain the history of life. There's an important part of evolutionary theory called "Hierarchical Theory" where proponents argue for higher-level mechanisms of evolution such as species selection. They aren't part of microevolutionary explanations. Thus, microevolution is necessary but not sufficient to explain macroevolution [Macroevolution].

-The video mentions the Galápagos finches. Do the finches represent an example of microevolution or macroevolution?

It's on the border between microevolution and macroevolution. The value of the work on the Galapogos finches is that the results suggest how new species are formed. They formed from a combination of physical isolation events (different islands) plus microevoutionary events involving natural selection, and random genetic drift. Such speciation events occurred repeatedly in the history of life and these studies show how they can be explained by purely natural causes.

-The video mentions mutations in fruit flies which gave fruit flies an extra pair of wings. Were these fruit flies able to fly better and survive with the extra wings?

No.

-Are mutations helpful or harmful? Ask for examples of harmful mutations? How about helpful ones?

A harmful mutation is one that decreases fitness. There are hundreds of examples of genetic diseases in humans. A beneficial mutation is one that increases fitness. Antibiotic resistance in bacteria is a classic example but so is HIV resistance in humans. Dozens of field studies have shown that beneficial mutations can arise fairly quickly in populations that are challenged by environmental change. Molecular data documents thousand of beneficial changes to genes and enzymes over time.

-What was the Cambrian explosion?

The Cambrian Explosion was a period in the history of life where we see the appearance of new types of animals. The dates are approximately 500 million years ago and the time frame for the visible appearance of these groups ranges from 10-50 million years. It's important to note that the fossils of the Cambrian don't look like any species that are alive today and they don't contain any examples of land life. It's also important to note that the Cambrian explosion doesn't apply to plants, fungus, protozoa, and bacteria.

What caused the appearance of primitive animal groups 500 million yeas ago, over a period of tens of millions of years? Scientists don't really know but there are lots of ideas on the table. One thing that's very clear from molecular evolution is that the origin of the various lineages (phyla) goes back several hundred million years.

-Does the fossil evidence show that species have evolved by small gradual changes, or large sudden changes? Do fossils support Darwin’s theory? Why or why not?

The are many examples of slow gradual changes over millions of year but there are also examples of patterns called Punctuated Equilibria. In these examples you see very small changes—such as the speciation events in the Galapagos finches—happening at the time of speciation. In other words, the fossil record mimics the sort of thing you see in the Galapagos islands where the small changes occurring at speciation are quickly fixed in the population within ten or twenty thousand years. There's hardly any fossil record of the intermediates showing the transition between these closely related species.

There's nothing in the fossil record suggesting that large sudden changes can occur rapidly. That's a lie propagated by creationists who don't understand evolution and who have a religious agenda that interferes with their ability to do science.

-The video also mentions the origin of life. Does the evidence support the claim that the building blocks of life were present on the early earth? Why or why not?

The origin of life is an interesting scientific problem that hasn't been solved. Although it has nothing to do with evolution, it's clearly related. Some scientists think that life arose in a primordial soup containing abundant supplies of all the necessary building blocks we see today. There is plenty of scientific evidence that some of these building blocks—such as simple sugars and amino acids—can arise spontaneously. In fact, many of them have been detected in outer space. Other scientists prefer scenarios where life began much more simply with very small, highly abundant, chemicals that are still around today in the oceans. It will be interesting to watch for new discoveries as you grow up because science is poised to make significant advances in these areas.

You should keep an open mind on this question and watch for new discoveries from religious leaders that will help you understand the origin of life. It's possible—alghough not very likely—that religious organizations such as The Discovery Institute will come up with a scientific explanation of how, and when, God created life on Earth.

-Compared to humans, was the first life simple or complex? How about compared to a calculator, computer, or cell phone? Are living organisms more or less complicated than human technology? What do students think?

All available scientific evidence points to a common ancestor that was much more simple than humans, or most other species that are living today. Those primitive ancestors are much less complex than a modern computer because, in addition to having only a few hundred genes (at most), the internal cell biology and biochemistry was undoubtedly sloppy and inefficient. No modern machine is anything like that.

We are at the stage in technology development where it is possible to build better life forms than those that evolved naturally and you should look forward to learning about these new artificial forms of life in the next few years. You might even want to think about a future career in science so you can learn this technology.

The Great Accommodationist Dud: Round 2

 
Point of Inquiry is a series of podcasts financed by the Center for Inquiry. Chris Mooney is one of the people CFI pays to produce the podcasts. He decided to continue the accommodationist debate with PZ Myers and selected the moderator from round 1 to step in for him on the podcast. Unfortunately, Jennifer Hecht doesn't understand the concept of "moderator" so the podcast ends up being Jennifer and Chris against PZ.

PZ does a good job but it's tough defending yourself against two people who are coming at you from very different directions. Jennifer Hecht does not sound very convincing to me. She seems to believe that "a little bit of religion" is perfectly compatible with science and shouldn't be challenged. Towards the end of the podcast, Chris tries to bring up the fact that there are people who find the Gnu Atheists annoying and offensive. PZ replies, very effectively, by pointing out that many people find Chris Mooney annoying, arrogant, and offensive but they aren't telling him to shut up! I would add Jennifer Hecht to the list of people I find arrogant,¹ annoying, and offensive.

Here's the podcast, it's a better utilization of your time than the first round was.

PZ Myers, Jennifer Michael Hecht, and Chris Mooney - New Atheism or Accommodation?

1. By my definition, you aren't "arrogant" if you are right. You are only arrogant when you are close-minded and wrong.

Is Thanksgiving Day a Religious Holiday?

 
Tomorrow is Thanksgiving Day in Canada. It a holiday marked by good meals and getting together with friends and family. I've never thought of it in any other context. But then, I treat Christmas the same way (except there are presents).

Douglas Todd is a columnist for the Vancouver Sun and he has a very different view of thanksgiving as expressed in his article: At Thanksgiving, do atheists feel grateful?.

Are atheists thankful? And, if so, to whom? Or what?

In the Pacific Northwest, which has the highest proportion of non-religious people in North America, Thanksgiving is not always simple for those who do not believe in a transcendent reality.

How do the almost two out five British Columbians who say they have no religion, and especially the 16 per cent who are atheists, approach a festive day that encourages humans to express a sense of thankfulness, particularly for life itself being a gift?

What is it with people who believe in supernatural beings—especially in those Gods who need to be thanked from time to time? Why are these believers completely incapable of seeing anyone else's point of view? Is there something about believing in "transcendent reality" that affects their brains?

The Great Accommodationist Dud

 
I watched the whole three hours streamed live on the conference website. It was about as exciting as watching paint dry except that drying paint doesn't make you angry. All four panelists managed to miss the point.

It wasn't until we got to the very last question that anyone grasped the important point; namely, that PZ Myers and Vic Stenger have very different goals than Chris Mooney and Genie Scott.

Chris and Genie want people like PZ and Vic to keep a lid on it because the Gnu Atheists are making their life more difficult. Tough. There's no reason why PZ and Vic (and the rest of us) have to share their goals just because they think they're more important than getting rid of religion.

And why did Vic and PZ allow Genie to get away with defining science as methodological naturalism?

I was very disappointed in everyone on the panel, and in the moderator.

Carnival of Evolution #28

 
I've been so busy lately that I forgot to mention the latest Carnival of Evolution. This is doubly embarrassing because it features one of my favorite blogs [Carnival of Evolution #28 - Featuring Sandwalk].

Be sure to answer the survey questions ...

WELCOME to the 28th edition of Carnival of Evolution! This time the carnival has returned home. Not since the first edition back in August 2008 has an edition been posted here. That is cause for celebration, so let's do that with a little survey. I am interested who reads Carnival of Evolution, so please spend the next two minutes tops taking this brief survey about yourself and CoE. Results will then be posted here for the bemusement of all.

The Velvet Underground of Molecular Biology

The Velvet Underground was a New York rock band in the 1960s. It was never very popular and never made much money but it's said to have influenced many other, more successful, bands.

Chad Orzel asks you to identify The Velvet Underground of Science by which he means an individual who isn't very famous but had a huge impact on science. Naturally, he has an example from physics.

I have an example from molecular biology. Max Delbrück (1906-1981) was one of the founders of the 'phage school (along with Salvador Luria). Delbrück began his science career as a physicist but when he went to the USA he switched to biology and soon became interested in bacteria and bacteriophage.¹ During the 40s, 50s, and 60s he had a huge influence on the members of the 'phage group who used to meet regularly at Cold Spring Harbor where Delbrück taught a summer course in 'phage genetics.

Jim Watson, Matt Meselson, Franklin Stahl, Gunther Stent, Seymour Benzer, Edward Kellenberger, and Alfred Hershey are just a few of the scientists who were directly influenced by Delbrück. They all got together to contribute to Phage and the Origins of Molecular Biology in 1966. The book was a Festschrift in honor of Max Delbrück on his 60th birthday.

There were many more second and third generation scientists who grew up in the 'phage group. My own supervisor used to refer frequently to Delbrück's "Principle of Limited Sloppiness" as an effective way of doing science.

Delbrück, Alfred D. Hershey, and Luria won the Nobel Prize in 1969 but he (Delbrück) is still not very well known among today's students. I think that every biochemistry and molecular biology student should have to read The Eighth Day of Creation by Horace Freeland Judson in order to learn the history of their field.

They might discover that much of what they think of as "modern" was actually understood almost half a century ago.

Three Conundrums

 
Razib Khan over at Gene Expression is discussing a recent article on epigenetics and other "revolutions" in molecular biology. Check out Razib's postings: Arise the vehicle! Arise the cell! and Epigenetics – what revolution?.

The article in question is by Steve Talbott¹ and it's published in The New Atlantis: Getting Over the Code Delusion. Here's how the editors introduce the article ...

Editor’s Note: This is the first in a planned set of essays by Mr. Talbott explaining the significance of a revolution in genetics and molecular biology that has only just begun to receive public attention. Although this essay is at times necessarily tech­nical, we trust that our readers will not find it prohibitively so — and we have appended a modest and informal glossary to help smooth the path.

You all know where this is going, don't you?

Talbot sets up his "revolution" by describing several problems.

A number of conundrums have helped to nudge molecular biology toward a more contextualized understanding of the gene. To begin with, the Human Genome Project revised the human gene count downward from 100,000 to 20,000–25,000. What made the figure startling was the fact that much simpler creatures — for example, a tiny, transparent ­roundworm — were found to have roughly the same number of genes. More recently, researchers have turned up a pea aphid with 34,600 genes and a water flea with 39,000 genes. Not even the "chimps are human" boosters were ready to set themselves on the same scale with a water flea. The difference in gene counts required some sort of shift in ­understanding.

I've addressed this before. Knowledgeable experts in the field were predicting 30,000 genes at least as far back as the late 1960s. Their predictions were very close to the mark [False History and the Number of Genes] [Humans Have Only 20,500 Protein-Encoding Genes] [Facts and Myths Concerning the Historical Estimates of the Number of Genes in the Human Genome]. Steve Talbot hasn't done his homework. This isn't a very auspicious beginning.

A second oddity centered on the fact that, upon "deciphering" the genetic Book of Life, we found that our coding scheme made the vast bulk of it read like nonsense. That is, some 95 or 98 percent of human DNA was useless for making proteins. Most of this "noncoding DNA" was at first dismissed as "junk" — meaningless evolutionary detritus accumulated over the ages. At best, it was viewed as a kind of bag of spare parts, borne by cells from one generation to another for possible employment in future genomic innovations. But that’s an awful lot of junk for a cell to have to lug around, duplicate at every cell division, and otherwise manage on a continuing basis.

In this day and age, anyone who equates junk DNA with non-coding DNA isn't worth reading. They've lost all credibility as far as I'm concerned.

Talbott explains the solution later on in his article when he says ...

So what’s going on? These puzzles turn out to be intimately related. As organisms rise on the evolutionary scale, they tend to have more "junk DNA." Noncoding DNA accounts for some 10 percent of the genome in many one-celled organisms, 75 percent in roundworms, and 98 percent in humans. The ironic suspicion became too obvious to ignore: maybe it’s precisely our "junk" that differentiates us from water fleas. Maybe what counts most is not so much the genes themselves as the way they are regulated and expressed. Noncoding DNA could provide the complex regulatory functions that direct genes toward service of the organism’s needs, including its developmental needs.

Anyone who states or implies that there is a significant correlation between total haploid genome size and species complexity is either ignorant or lying.

Larry Moran
Genome Size, Complexity, and the C-Value Paradox"Organism rise on the evolutionary scale"? Has Talbott done any research at all for this article? His understanding of evolution is no greater than kindergarten level if he believes that there's an evolutionary scale with us near the top.

The idea that noncoding DNA contains sequences that govern gene expression has been with us for fifty years. That's hardly revolutionary. The idea that the amount of junk DNA in a genome equates to complexity has been soundly disproven. The idea that humans might need a million base pairs of DNA to control expression of every gene is ludicrous and has absolutely no evidence to support it. In fact, nobody I know has ever shown that mammalian genes require more regulatory sequences than insect genes or those of crustaceans (water fleas). What we have here is a perfect example of The Deflated Ego Problem.

What about the third "conundrum"?

Another conundrum — perhaps the most decisive one — has been recognized and wrestled with (or more often just ignored) since the early twentieth century. With few exceptions, every different type of cell in the human body contains the same chromosomes and the same DNA sequence as the original, single-celled zygote. Yet somehow this zygote manages to differentiate into every manner of tissue — liver, skin, muscle, brain, blood, bone, retina, and so on. If genes determine the form and substance of the organism, how is it that such radically different cellular architectures result from the same genes? What directs genes to produce the intricately sculpted and differentiated form of a complex organism, and how can this directing agency be governed by the very genes that it directs?

We've known the basic answer to this "conundrum" for about five decades. Talbott's idea of a revolution is very strange.

Don't bother reading the article in The New Atlantis. There's nothing "new" there and it may make you very angry.

2010 Nobel Prize in Physiology or Medicine

 
The 2010 Nobel Prize in Physiology or Medicine was given to Robert G. Edwards "for the development of in vitro fertilization". They should have added "in humans."

This is a technological achievement, one that was based on years of work with other animals.

I do not favor awarding Nobel Prizes for technology. I prefer to give the science prizes to those who have advanced our fundamental understanding of the universe. This prize is for medicine, which is technology, so it doesn't violate any rules. But in the past the prize in Physiology or Medicine has usually been for basic research.

It worries me that there may have been non-scientific motives behind this year's selection. We saw a horrid example of that last year when the Nobel Peace Prize was announced and I hope this isn't a trend.

Here's an example of how the award is being treated in the press [British IVF pioneer Robert Edwards gets Nobel Prize].

As well as leading to a host of new treatments for infertility, the work also founded the principles behind stem cell research, cloning and techniques that would allow couples to prevent passing on inheritable diseases to their children.

Christer Höög, professor of molecular biology at the Karolinska Institute in Stockholm, and a member of the Nobel Prize Committee, said the birth represented a "paradigm shift"

"It showed for the first time that it is possible to treat infertility," he said.

Prof Edwards' work was highly controversial at the time and there was strong opposition to what was seen as 'playing God' and the research had to be privately funded.

The good news is that the Vatican is really, really, pissed! [Vatican official criticises Nobel win for IVF pioneer]. I think it's because the Roman Catholic Church is pro-life.

The Edge of Evolution

There are two main problems with Intelligent Design Creationism. The first is that the IDiots never have anything positive to offer by way of explanation. They complain about how evolution can never do this or that but they never give us a better explanation based on their beliefs. The second problem is that the IDiots often get their science wrong when they complain about evolution. Sometimes this is deliberate, but in many cases it's because they just don't understand what they're criticizing.

Their criticisms of evolution are based on the notion of a false dichotomy. They think that there are only two choices: their conception of evolution, or Intelligent Design Creationism. Thus, if they can refute their version of evolution it follows that creationism must be true.

People often make the claim that Intelligent Design Creationism isn't science. That may be true if you only think of it as promoting the idea of an intelligent designer but even there it depends on how you define science. However, much of the Intelligent Design Creationism literature isn't about defending creationism, it's about attacking evolution and those arguments definitely fall within the definition of science. As scientists, we have to deal with all the objections to evolution no matter what the motives of the challengers.

I think it's somewhat simplistic to dismiss all the Intelligent Design Creationist literature on the grounds that it's not science. Some of it has all the earmarks of science, it's just bad science. And bad science isn't limited to IDiots. I think there are many Theistic Evolutionists who are also guilty of promoting bad science and there are many atheist scientists who are just as guilty. The peer-reviewed scientific literature is full of examples.

Although it makes my American friends cringe, I favor teaching the controversy. It's the only way to show students the difference between good science and bad science.

Some of the Intelligent Design Creationists can craft pretty convincing arguments against evolution. It takes a lot of work to refute them. I going to give you an example of such an argument from The Edge of Evolution by Michael Behe. Let's see how you do.

---

The Two Binding Sites Rule

Behe's version of the history of life requires a God who intervenes quite frequently to create specific mutations that are almost impossible to account for by random mutation. Behe makes a good case for the problems with random mutation. In fact, his arguments are similar to those put forth by the mutationist camp—a group that I'm in sympathy with. Most biologists would not be able to refute Behe's arguments because they would agree with some of his false premises.

Behe's "Two Binding Sites Rule" is a good example. He argues that in order for two proteins to interact, evolution needs to create a small patch on the surface of each protein where five or six amino acid side chains become compatible with binding. Some of these changes could be neutral so they could arise independently but the analysis of hundreds of known binding sites shows that many of the mutations would be detrimental if they occurred by themselves—a single charged amino acid residue on the surface, for example.

It looks like you need to wait for three or four specific mutations to occur simultaneously in order to get a moderate interaction between two proteins that did not originally bind to each other. And these can't be just any proteins, they have to be proteins where there is a selective advantage to forming a complex. The example I've chosen is a bacterial photosynthesis reaction center where four polypeptides (gold, blue, green, purple) interact with each other and with multiple cofactors (space-filling molecules) to form a very complicated structure. Presumably, there was a time in the past when some of these proteins didn't bind to each other or to the cofactors. Over time, evolution favored variants that could form the complex. How could this happen according to evolutionary theory?

Studies on in vitro mutagenesis show that the probability of forming any de novo binding site is very low. For example, it's quite difficult to engineer specific antibodies that will bind to a particular antigen. The data shows us that you need a library of more than one billion antibody molecules in order to get one that will bind. Those one billion mutations are far from random. They are engineered so that they are confined to a small patch on the surface of the antibody where it is known that other proteins can potentially bind.

Behe argues from this evidence that the probability of creating a new binding site by random mutations is exceedingly small. So small, in fact, that such mutations would only arise in very large populations after several hundred million years of evolution. He bases his argument on some experiments he describes in the first few chapters or his book.

Behe points out that it is sometimes very difficult for the malaria-causing parasite, Plasmodium falciparum, to develop resistance to some drugs used to treat malaria. That's because the resistance gene has to acquire two specific mutations in order to become resistant. A single mutation does not confer resistance and, in many cases, the single mutation is actually detrimental. P. falciparum can become resistant because the population of these single-cell organisms is huge and they reproduce rapidly. Thus, even though the probability of a double mutation is low it will still happen.

If the probability of a single mutation is about 10^-10 per generation then the probability of a double mutation is 10^-20. He refers to this kind of double mutation as CCC, for "chloroquine-complexity cluster," named after mutation to chloroquine resistance in P. falciparum.¹ Behe's calculation is correct. If two simultaneous are required then the probability will, indeed, be close to 1 in 10²⁰.

Let's see how this relates to the evolution of protein-protein interactions. Here's how Behe describes it on page 135 of his book.

Now suppose that, in order to acquire some new, useful property, not just one but two new protein-binding sites had to develop. A CCC requires, on average, 10²⁰, a hundred billion billion, organisms—more than the number of mammals that has ever existed on earth. So if other things were equal, the likelihood of getting two new binding sites would be what we called in Chapter 3 a "double CCC"—the square of a CCC, or one in ten to the fortieth power. Since that's more cells than likely have ever existed on earth, such an event would not be expected to have happened by Darwinian processes in the history of the world. Admittedly, statistics are all about averages, so some freak event like this might happen—it's not ruled out by the force of logic. But it's not biologically reasonable to expect it, or less likely events that occurred in the common descent of life on earth. In short, complexes of just three or more different proteins are beyond the edge of evolution. They are lost in shape space.

We're all pretty knowledgeable here but how many of you can immediately refute that argument? If you can't then you have no business accusing Behe of being stupid or silly and of dismissing his book as just another example of creationist ignorance. The correct explanation of the problem will undoubtedly appear soon in the comments. Before peeking, why not try and see how you would answer Behe if you were debating him in front of a large audience of creationists?

---

1. Behe may have been wrong about the specific chloroquine resistance mutation he used as an example. The two mutations may not have occurred simultaneously. Nevertheless, the principle is sound. If the single mutations are detrimental then you need both to get resistance and the probablity of two such mutations occurring together is 10^-20.

Meeting God in Montreal

 
Brian Dalton is Mr. Deity. If you haven't been watching all the episodes over the past few years then go to the website and buy the DVD. You won't regret it.

Brian is as funny in person as he is on the videos. He explained how "Mr Deity and the Virgin" was inspired by a debate he saw on TV.

Brian's wife, Amy Rohren, plays "Lucy" (Lucifer, Satan), Sean Douglas plays Jesus, and Jimbo Marshall is God's chief of staff.



One of my personal favorites is "Mr. Deity and the Really Unique Gift."

A No-Brainer

 
It's been a week since I issued A Challenge to Theists and their Accommodationist Supporters.

This brings me to my challenge. I challenge all theists and all their accommodationist friends to post their very best 21st century, sophisticated (or not), arguments for the existence of God. They can put them in the comments section of this posting, or on any of the other atheist blogs, or on their own blogs and websites. Just send me the link.

Try and make it concise and to the point. It would be nice if it's less than 100 years old. Keep in mind that there are over 1000 different gods so it would be helpful to explain just which gods the argument applies to.

There have been over 500 comments on that posting and dozens of attempts to meet the challenge, ranging from the fact that Babylon hasn't been re-built to variations of the old Cosmological and Ontological Arguments that have been around for centuries.

I think it's fair to say that nobody came up with anything that even remotely resembles a modern "sophisticated" argument that the Gnu Atheists are ignoring. Therefore, I declare victory.

From now on, whenever any accommdationist or theist accuses me of not having studied philosophy or theology I'll point them to my post and remind them that the Emperor really doesn't have any clothes. That includes a few people who sent me email messages explaining why they wouldn't lower themselves to post a comment on my blog. They implied that they still had some really good arguments for the existence of God but they aren't going to reveal them to me because I wouldn't understand them.

Friends in Montreal

 
Seanna Watson, Steve Watson, Sue Strandberg, and a photo bomber.


This photo is from last night after dinner. Today at noon I was witness to the strangest phenomonon—before we could sneak away for lunch, there were no less than 14 people who deliberately took photographs of this man. Sometimes I had to photograph him with various people using their cameras.¹ What is it about this guy? He's not particularly photogenic.

The Sound of Science

 
This is cute, but it's also deeply troubling.

I really don't like Darwin worship. It's true that I think he was the greatest scientist who ever lived, but science has moved on since 1859. Modern scientists respect, but do not worship, the past.

There are a couple of other problems with the lyrics. I'm confused about the reference to "theory" as some kind of "abstraction" and I don't like the implication that we go back and read Darwin to refresh our memory about modern evolutionary theory.

I also don't like the simplistic explanation of how real science is done. It's a common myth that publishing a peer-reviewed paper is the only way to do science. There are two things wrong with this mythology. First are the obvious exceptions, Origin of Species being one of them. Second, there's plenty of bad science papers in the peer-reviewed literature. Publishing in the peer-reviewed literature is neither necessary, nor sufficient, as a measure of good science.
