Does an understanding of evolution help scientists understand the secrets of biology?

You're probably wondering why I would ask a question like, "Does an understanding of evolution help scientists understand the secrets of biology?" It's not my question. It's a paraphrase of a question asked by someone who goes by the pseudonym "PaV" on Uncommon Descent. Here's the full context from her post: Does Evolutionary Theory Really Help Scientists?

For a number of years, many of us at UD have made the argument that evolutionary theory, in practice, is of almost no help whatsoever in getting at the secrets of biology. I’ve taken the position personally that it actually hurts, and that it is not a matter of indifference to the study of biology whether evolution is employed or not. ID is the way to go.

Now, besides the fact that she is an IDiot, you may be asking why anyone would write such a thing.

Here's the scoop. Someone was looking at unknown RNAs in zebra fish and discovered that one of them encoded a protein that hadn't previously been characterized. This sort of thing happens all the time in various species so why is PaV so excited?

Here's the answer ...

They’ve studied this embryonic stage for 20 years, and couldn’t figure out the decisive signals for initiation of the gastrula. They had to look to “non-coding” RNA, i.e., “junk DNA,” in order to solve their new found secret.

And why didn’t they study “junk DNA” before? Well, evolutionary theory posits that it is “junk” (their word, not ours), so why investigate.

See? Evolutionary theory actually impedes scientific progress. And you wonder why we call them ....

The real war is between rationalism and superstition

Phil Plait of Bad Astronomy watched the debate between Bill Nye and Ken Ham. He decided that both of them are wrong because the debate was framed as a war between evolution and religion. Like a long list of accommodationists before him, Phil Plait thinks he has the answer in his post: The Creation of Debate.

I can’t stress this enough. The conflict over the teaching of evolution is based on the false assumption that evolution is antagonistic to religion. This is why, I think, evolution is so vehemently opposed by so many in the United States. The attacks on the specifics of evolution—the claims about irreducibility of the eye, for example, or other such incorrect statements—are a symptom, not a cause. I can talk about how we know the Universe is old until the Universe is substantially older and not convince someone whose heels are dug in. But if we can show them that the idea of evolution is not contrary to their faith, then we will make far, far more progress.

That’s not to say I’ll stop talking about the science itself. That still needs to be discussed! But simply saying science is right and faith is wrong will never, ever fix the problem.

And this won’t be easy. As long as this discussion is framed as “science versus religion” there will never be a resolution. A religious person who doesn’t necessarily think the Bible is literal, but who is a very faithful Christian, will more likely be sympathetic to the Ken Hams than the Bill Nyes, as long as science is cast as an atheistic dogma. For example, on the Catholic Online website, the argument is made that both Ham and Nye are wrong, and casts science as an atheistic venture.

That must change for progress to be made.

This is the classic accommodationist position. Problem is, it's been tried and it doesn't work in the United States. And the reason it doesn't work is that Americans aren't that stupid. They realize that these debates really are about science vs. religion. They know that evolution is, in fact, antagonistic to religion.

Jerry Coyne points this out rather forcibly in his response to Phil Plait. Read Coyne's article: Debate postmortem II: Phil Plait goes all accommodationist. I'll get back to Jerry Coyne in a minute but first let me quote Phill Plait's "solution."

And who should do this? The answer to me is clear: Religious people who understand the reality of science. They have a huge advantage over someone who is not a believer. Because atheism is so reviled in America, someone with faith will have a much more sympathetic soapbox from which to speak to those who are more rigid in their beliefs.

It's possible that "religious people who understand the reality of science" is a very small group and it's even more possible that they will be opposed to science and evolution precisely because they DO understand the reality of science. Plait is probably thinking about Ken Miller and Francis Collins but it's not clear to me that they truly understand what science is telling us. Science is telling us that there's no need for god(s) in order to understand the world around us. Evolution tells us that life has no purpose.

What Phil Plait is saying is that the best people to defend evolution are those who think that there really is a creator god but he/she/it mostly used evolution as a method of creation. In other words, we atheists should rely on theistic evolution creationists to convince other creationists to adopt a somewhat different view of creationism! That probably means we should keep quiet unless we are willing to make the case for one version of supernaturalism. Why would we do that?

That may be acceptable to some people but it misses the point of the conflict as far as many atheists are concerned. Jerry Coyne said it best in response to the accommodationist views of Micheal Ruse some years ago. Coyne's letter, which appeared in Playboy after Ruse's article was published, said ...

[Ruse] fails to grasp the real nature of the conflict. It's not just about evolution versus creationism. To scientists like Dawkins and Wilson, the real war is between rationalism and superstition. [my emphasis, LAM] Science is but one form of rationalism, while religion is the most common form of superstition. Creationism is just a symptom of what they see as the greater enemy: religion. While religion can exist without creationism, creationism cannot exist without religion.

This passage has been widely quoted and I wholeheartedly agree with Coyne's view.¹

For many of us the real war is between rationalism and superstition and the battle over evolution is just a minor skirmish in that war. What this means is that New Atheists are not inclined to recruit people who believe in superstition in order to fight a war against superstition.

That may be acceptable to people like Phil Plait because they're not interested in fighting a war against all forms of superstition, including religion. Instead, they seem content to promote some forms of superstition over others. The accommodationists should not expect all atheists to agree with them and they should acknowledge the fact that many of us think science and religion are incompatible.²

1. There's some doubt about whether Coyne actually said this in his letter. I'm quoting a second-hand source: Dawkins in The God Delusion.

2. I'm not saying we are correct. I'm just saying that after all these years it's disappointing to see so many accommodationists who just don't get it.

Creationist scientists and bottoms of barrels

One of the interesting quirks of creationists is their intense desire to gain credibility by finding religious scientists who agree with them about god(s) and creation. We saw a good example in the Ken Ham vs Bill Nye debate where Ken Ham managed to find several people who are Young Earth Creationists but nevertheless made a contribution to science or technology. Some were physicians and some were engineers but some were actually scientists [see the debate at: Bill Nye Debates Ken Ham].

I'm reminded of a passage in The God Delusion (p. 100) where Richard Dawkins says ...

The efforts of apologists to find genuinely distinguished modern scientists who are religious have an air of desperation, generating the unmistakably hollow sound or bottoms of barrels being scraped.

Dawkins goes on to point out that efforts to find creationist Nobel Prize winners in Physics, Chemistry, or Physiology & Medicine have been largely unsuccessful.

IDiots discover that RNA has secondary structure

I suppose we should be happy whenever some IDiots manage to educate themselves but somehow I find it quite sad when it takes thirty or forty years. Here's an example of a somewhat late-blossoming IDiot who posts on Evolution News & Views (sic): RNA Shows Design, Too. She doesn't sign her name to the post—I think I know why.

Here's what she just discovered ...

RNA differs from DNA in one of the sugars that makes up its backbone and one of the bases that makes up its side branches (uracil instead of thymine); it is also usually found in single strands instead of DNA's double helix. New discoveries, though, are showing RNA does far more than passively transfer DNA's information to other places. It, too, is a masterpiece of intelligent design and function.

A paper in Nature describes how information is stored not only in RNA's base sequence, but in its folds. Because RNA has more degrees of freedom, it can take on a wide variety of forms not possible for DNA. "RNA has a dual role as an informational molecule and a direct effector of biological tasks. The latter function is enabled by RNA's ability to adopt complex secondary and tertiary folds and thus has motivated extensive computational and experimental efforts for determining RNA structures," the authors begin (emphasis added). In their conclusion, they say, "We identify hundreds of specific mRNA regions that are highly structured in vivo, and we show for three examples that these structures affect protein expression."

The paper by Rouskin et al. (2014) reports on the development of new software to detect secondary structure in RNA. This is news for IDiots who think that "new discoveries" show that RNA is capable of catalysis and other functions.

Think about that for a minute. This is 2014, it's 25 years since Sidney Altman and Tom Cech were awarded the 1989 Nobel Prize in Chemistry and more that 30 years since undergraduates were routinely taught about catalytic RNAs in introductory biochemistry courses. Those IDiots sure are slow learners.

In other words, the structure, not just the sequence, carries functional information.

Amazing. Sounds like they've never heard of the idea that ribosomal RNA catalyzes peptide bond formation and that it does so through secondary structure. They've never heard of self-splicing introns. All they have to do is read an introductory textbook of biochemistry or molecular biology.

Now if you connect this amazing new bit of information to the equally astonishing (not!) news that some lincRNAs have a function, you get this ....

More design found in what was formerly called junk; more information found parallel to existing information in RNA; more power found in the collective energy of intelligent agents. Why are you not surprised?

The real question is why are IDiots surprised by routine information that even high school students know?

And what does this have to do with intelligent agents? Has this person answered the quiz?

A quiz for those of you who think you understand Intelligent Design Creationism

One of the great ironies of the Intelligent Design Creationist movement is that its proponents don't understand evolution and they don't understand what their movement stands for. They can't agree on the meaning of intelligent design.

You might think I'm exaggerating about not understanding their own goals but just think about it for a moment. The movement encompasses people like Michael Denton who promote a deist version of creation and it also welcomes huge numbers of Young Earth Creationists who believe in the literal truth of the biblical creation myth. Many proponents are somewhere in between these extremes but the vast majority think that there's something seriously wrong with evolution that demands the intervention of an intelligent designer. The designer may have just made bacterial flagella and a few other complex molecular machines or he/she may have stepped in to make all the animal phyla. Almost every proponent of Intelligent Design Creationism thinks that the designer intervened in the human lineage to make humans special.

Someone named "nullasalus" thinks that it's only critics of Intelligent Design Creationism who are confused. He tries to set us straight at: A Quiz for Intelligent Design Critics.

In the near decade that I’ve been watching the Intelligent Design movement, one thing has consistently amazed me: the pathological inability of many ID critics to accurately represent what ID actually is, what claims and assumptions are made on the part of the most noteworthy ID proponents, and so on. Even ID critics who have been repeatedly informed about what ID is seem to have a knack for forgetting this in later exchanges. It’s frustrating – and this from a guy who’s not even a defender of ID as science.

I try really hard not to misrepresent the Intelligent Design Creationist movement. That includes my preference for adding the word "Creationist" to their label. What they're talking about is creationism—a being who creates the universe and who creates some aspects of living organisms.

It's never easy to say exactly what "the most noteworthy ID proponents" mean by intelligent design. That's because they can't agree among themselves. The most common characteristic is that they are all anti-evolution in one way of another. Some of them accept microevolution and some accept common descent but almost all of their writings focus on some aspect of evolution that they don't accept. It could be the idea of junk DNA, or the evolution of animals in the Cambrian, or any one of a long list of "icons of evolution" that scientists get wrong.

A great many prominent ID proponents are opposed to "materialism"—that means they support non-materialism, otherwise known as supernaturalism (e.g. founder Phillip Johnson). A great many prominent ID proponents try to paint all supporters of evolution as social Darwinists. They try to link us to Nazis and they go out of their way to denigrate Charles Darwin. This seems to be an integral part of the Intelligent Design Creationist movement and it can't be ignored.

Just read the titles of the major ID books. They are all about attacking evolution.

Pete Seeger (1919 - 2014)

Pete Seeger is dead. That means something to those of us who grew up in the 1960s. It was a time when opposition to war was so strong and so powerful that we thought it might bring an end to all wars.

We were so naive.

Peter Seeger wrote one of the most famous anti-war songs of all time, "Where have all the flowers gone." Peter, Paul, and Mary made it a big hit—and so did others. Here's Pete Seeger singing with them for the last time. This should be the anthem that marks the 100th anniversary of the beginning of World War I.

When will we ever learn?


We will be in Greenwich Village this weekend and I'll be thinking of Pete Seeger. Seeger also wrote "Turn! Turn! Turn!" Here's the best version by the Byrds: "A time for peace, I swear it's not too late."

Hat Tip: Jerry Coyne

Seven things you need to know about evolution

John Hawks is a pretty cool guy. He studies anthropology with a special emphasis on the genetics of human evolution over the past million years or so. Right now he's in Ethiopia looking at fossils. I visited him a year ago at his lab in Madison, Wisconsin.

He written a summary of seven things about evolution. You should read what he has to say to see if you know enough about evolution. Here's a list of the seven things but each one requires a bit of explanation.

1. Evolution is change in a population
2. Evolution is genetic change
3. Many kinds of genetic changes are important to evolution
4. Evolution can be non-random
5. Evolution can be random, too
6. Populations evolve all the time
7. Evolutionary theory has changed a lot since Darwin's day

Monday's Molecule #230

Last week's molecule was cholesterol [Monday's Molecule #229]. The figure shows how the molecule would look in a lipid bilayer (membrane). The winner was Tommy Stuleanu.

This week's molecule (below) is going to be hard. I won't be surprised if nobody gets the right answer. It's a key intermediate in an extremely important reaction. You need to give the common name AND the the overall reaction. Name the enzyme as well.

Email your answer to me at: Monday's Molecule #230. I'll hold off posting your answers for at least 24 hours. The first one with the correct answer wins. I will only post the names of people with mostly correct answers to avoid embarrassment. The winner will be treated to a free lunch.

There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your email message.)

Territorial demarcation and the meaning of science

Massimo Pigliucci doesn't get enough respect. He's upset by the "New Atheists" who place a great deal of emphasis on the scientific way of knowing and demand evidence that any other way of knowing is successful. These mean New Atheists (I count myself as one of them) use a very broad definition of science that includes most of the admirable activities of philosophers. Pigliucci is mostly a philosopher and he doesn't think that philosophy is getting enough respect from the New Atheists.

Here's the cartoon he published on his blog to illustrate the problem [see Rationally Speaking cartoon: Sam Harris].

Changing high school education: Equinox Summit and Learning 2030

I recently re-watched a program on The Agenda about high school education and what needs to be done to make it better. The broadcast was from the Perimeter Institute in Waterloo, Ontario, Canada and it featured the results of a conference on learning called the "Equinox Summit" organized by the Waterloo Global Science Initiative in collaboration with the Perimeter Institute. You can watch the final episode of the TV show at: The Agenda: What's Necessary? What's Possible?.

If you are interested in this subject, as I am, you should watch this show since it gives you a good perspective on what the "best minds" are thinking. You can make up your own mind about whether this is encouraging or not.

Here's a short video on the summit ...



The communique from Equinox Summit: Learning 2030 isn't very long so you can read it quickly. Here are the goals that this group decided on.

In order for high school graduates to reach their full potential in life, they need to be:

• lifelong learners who can identify and synthesize the right knowledge to address a wide range of challenges in a complex, uncertain world
• literate, numerate, and articulate
• creative, critical thinkers
• able to collaborate effectively with others, especially those of different abilities and backgrounds
• open to failure as an essential part of progress
• adaptable and resilient in the face of adversity
• aware of the society they live in and able to understand the different perspectives of others
• self-aware and cognizant of their own strengths and limitations
• entrepreneurial, self-motivated, and eager to tackle the challenges and opportunities of their world

To achieve these goals, we require a radically di fferent structure for learning in 2030, one in which traditional concepts of classes, courses, timetables, and grades are replaced by more flexible, creative and student-directed forms of learning. This develops deep conceptual understanding, which can then be applied in other contexts.

There's nothing radical about these goals. They're pretty much the same goals that any conference in the 1960s would have come up with. The only really new buzzword is "entrepreneurial"—that's borrowed from business and it wouldn't have been popular in the 1960s. Today every high school student has to be an entrepreneur because by 2030 nobody will be working for anyone else. They'll all be running their own businesses.¹

I've been trying to teach creative and critical thinking for a long time and I haven't come up with any really good ideas. It's probably because I'm too old. You should watch the Agenda show to see how young people are going to solve these problems.

But here's a question that occurs to me as I'm thinking critically about this problem. Let's assume that we can achieve all those goals. Let's assume that in order to graduate from high school you have to have learned how to think critically; be literate, numerate, and articulate; be able to collaborate, be entrepreneurial, be adaptable, etc.

They are laudable goals that I support, but what percentage of students entering high school can achieve them? I'm thinking that, with lots of resources and excellent teachers, it might be possible for about 50% of high school students to reach these lofty goals. The rest are going to achieve the goals of learning to be "open to failure as an essential part of progress" and how to be "adaptable and resilient in the face of adversity."

I think we might have trouble convincing most societies, and most governments, that a 50% graduation rate from high school is the price of higher standards.

I'm not even sure that all of the students graduating from the University of Toronto are literate, numerate, articulate, critical thinkers.

Has John Brockman's stable lost its edge?

John Brockman is a famous literary agent. Over the years he has assembled a group of intellectuals, and people who aspire to be intellectuals. Every year they publish short articles on the question of the year at the Edge. Here's this year's question: annual question.

Science advances by discovering new things and developing new ideas. Few truly new ideas are developed without abandoning old ones first. As theoretical physicist Max Planck (1858-1947) noted, "A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it." In other words, science advances by a series of funerals. Why wait that long?

WHAT SCIENTIFIC IDEA IS READY FOR RETIREMENT?
Ideas change, and the times we live in change. Perhaps the biggest change today is the rate of change. What established scientific idea is ready to be moved aside so that science can advance?

There was a time—about a decade ago—when reading the answers to the question was exciting and stimulating.

Jerry Coyne picks two answers that deal with evolution: The Edge question: two bad answers about evolution. Roger Highfield's answer to the question of what idea should be retired is "Evolution is true." Kevin Kelly thinks that the idea of "Fully random mutations" should be tossed in the scrap heap of history.

Jerry shows us why these guys are not intellectuals. Read his blog post.

Lest you think that Jerry found the only bad examples, let me point out another one. Athena Vouloumanos is a psychologist at New York University. The idea that she wants to retire is "Natural Selection is the Only Engine of Evolution." Excellent, I thought, at last somebody has a good answer. Alas, here's what she says ...

Epigenetic control of gene expression contributes to cells in a single organism (which share the same DNA sequence) developing differently into e.g. heart cells or neurons. But the last decade has shown actual evidence–and possible mechanisms–for how the environment and the organism's behavior in it might cause heritable changes in gene expression (with no change in the DNA sequence) that are passed onto offspring. In recent years, we have seen evidence of epigenetic inheritance across a wide range of morphological, metabolic, and even behavioral traits.

The intergenerational transmission of acquired traits is making a comeback as a potential mechanism of evolution. It also opens up the interesting possibility that better diet, exercise, and education which we thought couldn't affect the next generation–except with luck through good example–actually could.

If I had to give a reason why natural selection is not the only engine of evolution I would have picked something very different—something that's been around, and proven, for decades. Epigenetics requires DNA sequences and proteins and if epigenetic modification of a specific DNA site provides a selective advantage under some circumstances then that's natural selection in action.

The Biology of Faith and Religion

Rufina Kim has re-started the discussion group we had last year. Join us for an evening of interesting conversation in room 5243 on the 5th floor of the Medical Sciences Building at the University of Toronto (Toronto, Canada). Bring your own food and beverage. The date is Wednesday, January 29, 2014 and the time is 6pm.

Everyone is welcome. You don't have to be a student or a faculty member to attend. Add your name to the list on Facebook at The Biology of Faith and Religion.

Is there a God? Why is the majority of the global population religious (and why are some not)? Why does religious faith lead to resistance in the face of scientific evidence? Why are research findings in evolutionary biology and cosmology still contentious among the public, while those in chemistry and physiology are not? What are the implications of religious belief in scientific progress?

These are some of the questions we will delve into at our next Thoughts on Science (TOS) meeting. Individuals of all worldviews are encouraged to attend to enlighten and be enlightened.
