James Lunney has quit the Conservative Party of Canada and decided not to run in the next federal election. He's upset because he doesn't believe in evolution and lots of people, including me, are pointing out the stupidity of his views. Because those views are based on religion, he interprets this to be an attack on his faith.
Here's what he says on his website [Evolution Controversy].
Maybe it’s because I am tired of seeing my faith community mocked and belittled. To not respond is to validate my accusers and worse yet, imply that I lack the courage of my convictions to stand–up for what I believe. This is not a legacy I wish to leave behind. Many of you colleagues represent constituencies beyond the ones who elected you; I hope that no member of any faith community in Canada is compelled to defend the beliefs of their community in the future.
Freedom of Religion and conscience are fundamental freedoms in Canada. Bigotry cloaked in defense of "science" is as intolerable and repugnant as bigotry from any other source.
It is contrary to our multi-racial, multicultural and multi-faith character and the tolerance for diversity that defines us as Canadians.
I know members on all sides of the house are concerned about bullying in general and cyber-bullying in particular. The government has brought in new legislative measures to address some aspects of this brutal phenomenon and there are many social actions like the pink shirt initiative that seek to shield the vulnerable.
We are living in an era where knowledge is increasing at an astounding pace; there are so many technical advances it is hard to keep up and what we refer to in general as "science" has been parsed into more and more diverse pursuits of knowledge.
I urge you to read the entire article that he posted on April 1st 2015. See if you think he deserves the respect he craves. He sounds like a kook to me.
How many times have we heard this stuff before? And how many times have we seen this style of writing?
So is "Evolution Theory or Fact?
The late Stephen Jay Gould stated: "a fact is something that is proven to the extent that to not believe it is perverse"!
That translates to: a fact is something that my friends and I believe, AKA eminence-based science. There’s a lot of that in health-care, where it’s known as eminence-based medicine as opposed to evidence- based medicine. There are people in the medical world expressing concern about the immense influence of KOLs (Key Opinion Leaders) with influencing public policy and decision making in directing scientific inquiry
Darwin’s brilliant and convincing construct that defined a century and a half of scientific belief, is in crisis because of astounding advances in molecular biology and it’s all about THE CELL.
You have 80-100 trillion cells, 200 cell types, all reading the same genetic library, but as different as they are, working together in specialized communities to perform astonishing synchronized manufacturing, recycling, transport, packaging and delivery functions. Twenty-five thousand miles of blood vessels if you strung them end to end; that is a trip around the world at the surface.
Every cell is worlds within worlds of nanotechnology finely tuned and regulated.
Darwin’s elaborate construct is stalled at the cell; even the simplest prokaryotic cell is infinitely beyond the odds of ever coming together by random, undirected process.
Jame Lunney is attacking evolutionary biologists and their acceptance of the scientific evidence for evolution, which happens to be their area of expertise. It seems ironic that he accuses others of bigotry and bullying.
James Lunney is a chiropractor and he has a B.Sc. (science). He says, "I have a background in Science: my credentials modest as they are, are superior on this file to many in this chamber and most of my critics."
That explains a lot.
Some of you may recall James Lunney, Conservative Party Member of Parliament for Nanaimo-Alberni in British Columbia. He's a chiropractor who spoke out against evolution back in 2009 [James Lunney: Creationist, Chiropractor, Conservative].
More recently, he defended another MP who didn't believe in evolution. He was mocked and ridiculed in the popular press and now he has decided to resign from the Conservative Party and sit in the House of Commons as an Independent. That's not working out so well according to CBC News [James Lunney defends views on evolution in House of Commons].
One day after he announced he was leaving the Conservative caucus to better defend his religious beliefs, Nanaimo-Alberni MP James Lunney attempted to do just that from his new seat in the corner of the House of Commons reserved for independent MPs.
But despite his best efforts, he was unable to convince House of Commons Speaker Andrew Scheer that the "cyberbullying" and "crowd-shaming" that he claimed to have experienced after questioning the science behind evolution constituted a breach of his parliamentary privilege.
Imagine that! He was unable to convince Parliament that making fun of his silly beliefs is wrong! This is exactly how the Canadian public SHOULD deal with people who act like kooks.
Wanna hear about his beliefs? This is what he said in Parliament ....
Speaking to CBC News Power & Politics host Evan Solomon on Wednesday evening, Lunney said that he was tired of seeing his faith community bullied.
...
Lunney described evolution — or, as he calls it, "macro-evolution" is "a theory in crisis."
"Scientists are not able to speak their mind on that — at least half of them who feel this way, they're gagged by an old construct," he argued.
"There's a whole generation of kids being taught that what they're taught in Sunday School or in church is garbage, it's wrong, it's false, and it's simply a form of bullying that's no longer acceptable. It's not scientifically tenable, it's a disservice to science… it's not freedom of religion if your views are put down by your peers."
Freedom comes in several forms. If you live in a free society then you have to be prepared to accept criticism of your most cherished beliefs. You can't hide behind religion to protect you when you act like an IDiot. Pointing out the stupidity of a Member of Parliament is not bullying
As far as I'm concerned, this is exactly how freedom should work.
Edward Lanphier, Fyodor Urnov, Sarah Ehlen Haecker, Michael Werner and Joanna Smolenski have published a comment in Nature with a provocative headline "Don’t edit the human germ line. They are asking scientists to agree " not to modify the DNA of human reproductive cells." The idea is that editing the genome of sperm or egg cells produces changes that will be passed on to future generations and this poses certain dangers.
I looked forward to this "conversation" because I was already familiar with Denis Noble and his strange views of evolution [A physiologist thinks about evolution]. Noble reiterated his view of modern evolutionary theory at the meeting. He thinks that modern evolutionary theory (The Modern Synthesis or Neo-Darwinism) is all about random mutation and natural selection. He thinks it is based on the views of Richard Dawkins in The Selfish Gene. Neither he nor Michael Joyner (an anaethesiologist at the Mayo Clinic) have learned about random genetic drift or Neutral Theory and neither of them have much knowledge of population genetics. In other words, they are pretty ignorant about evolution even though they feel entitled to attack it.
There's a shuttle bus that runs between my hotel in Boston and the convention center where Experimental Biology takes place. I went down to the hotel lobby this morning to catch the shuttle bus. The first clue that something was amiss was the four policemen in their yellow jackets sitting in the lounge. Their big bikes were parked just outside. The second clue was a larger than normal number of people waiting for cabs and shuttle buses.
All of a sudden, the cops left and so did all the taxis and shuttles without any passengers. That was also a clue.
The hotel informed us that there would be no shuttles to the conference center this morning, no shuttles to the airport, and no taxis because the President of the United States and the Vice-President were arriving.1 This requires shutting down I90 for several hours.
I decided to eat breakfast in the restaurant and wait out the disruption. (There wasn't anything interesting going on at the meeting this morning anyway.) I watched the motorcade go by on the Interstate. There were about a dozen cars lit up like Christmas trees, including an ambulance with lights flashing. Most of the lights were blue but there was a pretty mixture of yellow, red, orange, and green.
Judging by the number of angry people in the lobby, I can understand why the President and Vice-President need so much protection.
1. They are attending the opening of the Edward M. Kennedy Institute.
I'm at the Experimental Biology meetings in Boston and yesterday I dropped into a session on "Training the Mind of an Interdisciplinary Scientist." There were talks on how to resolve disputes among member of the interdisciplinary team, and on how to choose a problem that your customers want solved (from an engineer). There are was also a talk from the University of Missouri-Kansas City about their graduate program. Every single graduate student has to choose an interdisciplinary problem for their thesis topic and they have to take a half dozen courses in each of two disciplines (at least).
The only experience I've had with being interdisciplinary is when I tried to understand what computer scientists were interested in and whether we could work together on some problems. We couldn't. The gap was too large. So biochemists have just adopted the tools and techniques of computational sciences and moved on.
Very few of my colleagues are doing interdisciplinary research and they seem to be getting along just fine. Is this whole "interdisciplinary" thing just a fad? Do you know anyone whose main area of investigation spans two distinct disciplines?
I got the distinct impression from the session that there's pressure from university administrations and granting agencies to become interdisciplinary. Is this true?
A recent issue of Nature contains a report on plant micro-RNAs (Lauressergues et al., 2015). The authors found that certain genes for plant micro-RNAs encoded short peptides in the micro-RNA precursors and those peptides seemed to have a biological function. What this means is that part of the longer precursor RNA that is cleaved to produce the final micro-RNA may have a function that wasn't recognized. If you thought that the part of the precursor that was thought to be discarded as useless junk was, in fact, junk, then you were wrong—at least for some genes.
This is not a big deal and the authors of the paper don't even mention junk DNA.
The paper was reviewed by Peter M. Waterhouse and Roger P. Hellens in the same issue (Waterhouse and Hellens, 2015). They think it's a big deal. Here's what they say,
Students in my molecular evolution course have to write an essay. They can pick any topic they like as long as it's related to evolution and some controversy in the scientific literature. I have to approve the topic. The idea is that the students have to critically evaluate both sides of an issue and pick a side that they can defend.
The essays tell me a lot about what things are interesting in the course and how well the students understand the topics. Here are this year's topics.

The genetic code is redundant. Many amino acids have multiple codons ranging from two to six. The different codons for the same amino acid are called "synonymous" codons.
As sequences of protein-coding genes began to accumulate in the 1980s, it became apparent that different synonymous codons were used preferentially in different species. The phenomenon became known as codon bias. By 1990 it was known that the frequency of codon usage was correlated with tRNA abundance. As a general rule, there is a different tRNA for each codon and if multiple codons exist for a given amino acid then insertion of that amino acid into protein will depend on different tRNAs carrying the same amino acid.
There was a short article in a recent issue of Science that caught my eye. The title was "Statistics requantitates the central dogma."
As most Sandwalk readers know, The Central Dogma of Molecular Biology says,
... once (sequential) information has passed into protein it cannot get out again (F.H.C. Crick, 1958)
The central dogma of molecular biology deals with the detailed residue-by-residue transfer of sequential information. It states that such information cannot be transferred from protein to either protein or nucleic acid. (F.H.C. Crick, 1970)
You might wonder how you can quantify the idea that once information gets into protein it can't flow back to nucleic acids. You can't, of course.
The authors are referring to the standard scheme of information flow from DNA to RNA to protein. This is often mistakenly referred to as the Central Dogma by those scientists who haven't read the original papers. In this case, the authors of the Science article are asking whether the levels of protein in different cells are mostly controlled at the level of transcription, translation, mRNA degradation, or protein degradation.
Mary Lyon died on Christmas day last December. She was 89 years old.
She was a famous mouse geneticist who spend most of her working career at the MRC labs in Harwell, United Kingdom (near Oxford). The labs are known as an international center for mouse genetics.
Mary Lyon is famous for discovering the phenomenon of X chromosome inactivation. This is when one the the X chromosomes of female mammals is selectively inactivated so that the products of the X chromosome genes are quantitatively similar to the dosage in males where there's only one X chromosome. The phenomenon used to be referred to as Lyonization.
I never met Mary Lyon but from what people say about her, I'm sure I would have liked her. Here's an excerpt from the obituary in Nature: Mary F. Lyon (1925 - 2014).
Lyon was a central figure in twentieth-century mouse genetics. She laid the intellectual foundations and developed the genetic tools for the use of mice as model organisms in molecular medicine, cell and developmental biology and in deciphering the function of the human genome. Lyon was editor of Mouse News Letter from 1956 to 1970, a publication that had a key role in establishing a mouse-focused research community in the pre-Internet age. She also helped to develop a common language for the field by chairing the Committee on Standardised Genetic Nomenclature for Mice from 1975 to 1990. Her pivotal contribution was recognized by the naming of the Mary Lyon Centre, an international facility for mouse-genetic resources, opened at Harwell in 2004, and by the creation of the Mary Lyon Medal by the UK Genetics Society in 2014.
Because everything Mary said was so carefully thought through, she could be difficult to talk to: on the phone, it was easy to think you had been cut off. She did not suffer fools gladly, but was a great supporter of the bright young scientist, often eschewing authorship of publications to enhance the profile of junior collaborators. She was intellectually rigorous but not dictatorial. When I began my PhD with her in 1977, she gave me a handful of papers, showed me the genetic tools — mice carrying the various mutations and chromosomal rearrangements — and said, “do something on X-inactivation”. That degree of academic freedom was exhilarating, coupled as it was with the safety net of robust critique.
... Her first love was mice, although she always had a cat — a tortoiseshell, of course.
X chromosome inactivation is one of the classic examples of epigenetics, sensu stricto. It was the subject of one of my most popular posts of all time: Calico cats. Calico cats almost always have to be female but there are very rare examples of male calico cats. Can anyone figure out why?
Double-stranded DNA forms a helical structure where the two strands are twisted into a helical shape. If you think of the base pairs forming a ladder then imagine that the entire ladder could be distorted by rotating the ends relative to each other. The result would be the helical shape of DNA. The twisting results mainly from the attraction between the planar base pairs (rungs of the ladder.) They are "happier" when they are stacked close together right on top of each other. (The "force" is called "stacking interactions.")
This is not how DNA is actually built since there's never a time inside the cell when the DNA forms a ladder-like structure that's not helical, but you get the picture. [The Three-Dimensional Structure of DNA]
The final form of double-stranded DNA on the right is a cartoon used to illustrate certain features. I've deliberately drawn it with about 10-11 base pairs per turn so you can see the shape of the helix.
Conrad Black, also known as Baron Black of Crossharbour, KSG, was stimulated by a conversation with Christian apologist, and physicist, John Lennox. Black decided to write a column for the National Post (Toronto, Canada): Conrad Black: The shabby, shallow world of the militant atheist.
Richard Dawkins tweeted ...
Conrad Black seems to be at large again. Spot the factual errors, illogicalities and failures to understand.
Good advice. I wonder how many can be packed into a brief diatribe?
Keep in mind that no matter how many strawmen are erected, the important issue is whether gods exist. If you are a Christian, and you are going to attack the "shabby, shallow world" of atheists then the very least you can do is present your strongest case for the existence of gods.
Check out Conrad's Black's evidence for the existence of gods. (Warning: you will have to ignore all the rhetoric about the benefits of religion because it isn't relevant. On the other hand, there's a certain enjoyable irony in reading about how Christians are more moral than atheists.)
I really hate it when publishers start to hype a book several months before we can read it, especially when the topic is controversial. In this case, it's Oxford University Press and the book is "The Deeper Genome" Why there is more to the human genome than meets the eye." The author is John Parrington.
The title of the promotion blurb is: How the Genome Lost its Junk on the Canadian version of the Oxford University Press website. It looks like this book is going to be an attack on junk DNA.
We won't know for sure until June or July when the book is published. Until then, the author and the publisher will have free reign to sell their ideas without serious opposition or push back.
Here's the prepublication hype. I'm going to buy this book and read it as soon as it becomes available. Stay tuned for a review.
It's always fun to be quoted in The New York Times Magazine but there's a more serious issue to discuss. I'm referring to a brief article about online comments after Carl Zimmer published a piece on "Is Most of Our DNA Garbage?" a few weeks ago. If you read the comments under that article you'll discover that we have a lot of work to do if we are going to convince the general public that our genome is full of junk.
