The latest issue of Evolution: Education and Outreach contains a review of two books about evolution written by philosophers. The author of the review is Egbert Giles Leigh Jr. You can read it for free at: Questions about NeoDarwinism: a review of two books.
The books are,
Mind and Cosmos: Why the Materialist NeoDarwinian Conception of Nature is Almost Certainly False by Thomas Nagel. New York: Oxford University Press, 2012. ISBN 978-0-19-991975-8.
Are You an Illusion? by Mary Midgley. New York, NY: Routledge. 2014. ISBN 978-1-84465-792-6.
Both of these books challenge the idea that random mutation and natural selection can explain the world we see around us today.
The reviewer responds with a defense of natural selection from an adaptationist perspective.
I think Nagel and Midgley are wrong but for different reasons. I think that the history of life is the culmination of many random and accidental events and it could easily have gone in different directions [see Replaying life's tape]. I also think that lots of modern features are epiphenomena and not adaptations. Consciousness, to the extent that it actually exists, is one of them.
Nevertheless, Leigh's review is interesting and informative and I urge you to read it if you are interested in knowing why philosophers attack evolution. It helps us understand, once again, where philosophy is going wrong.
Today, while searching for articles on junk DNA, I came across a review of Nessa Carey's book published in The American Biology Teacher: DNA. The review was written by teacher in Colorado and she liked the book very much. Here's the opening paragraph,
The term junk DNA has been used to describe DNA that does not code for proteins or polypeptides. Recent research has made this term obsolete, and Nessa Carey elaborates on a wide spectrum of examples of ways in which DNA contributes to cell function in addition to coding for proteins. As in her earlier book, The Epigenetics Revolution (reviewed by ABT in 2013), Carey uses analogies and diagrams to relate complicated information. Although she unavoidably uses some jargon, she provides the necessary background for the nonbiologist.
The author of the review does not question or challenge the opinions of Nessa Carey and, if you think about it, that's understandable. The average biology teacher will assume that a book written by a scientist must be basically correct or it wouldn't have been published.
That's not true, as most Sandwalk readers know. You would think that biology educators should know this and exercise a little skepticism when reviewing books. Ideally, the book reviews should be written by experts who can evaluate the material in the book.
Now we have a problem. The way to correct false information about genomes and junk DNA is to teach it correctly in high school and university courses. But that means we first have to teach the teachers. Here's a case where professional teachers have been bamboozled by a bad book and that's going of make it even more difficult to correct the problem.
The last paragraph of the review shows us what influence a bad book can have,
As a biology teacher who enjoys sharing with students some details that go beyond the textbook or that challenge dogma, I enthusiastically read multiple chapters at each sitting, making note of what I cannot wait to add to class discussions. “Junk DNA” may be a misnomer, but Junk DNA is an excellent way of finding out why.
Oh dear. It's going to be hard to re-educate those students once their misconceptions have been reinforced by a teacher they respect.
We've been having a discussion on another thread about ID proponents. Are some of them acting in good faith or are they all lying and deceiving their followers?
I have similar problems about many scientists. I've been reading up on pervasive transcription and the potential number of genes for noncoding, functional, RNAs in the human genome. As far as I can tell, there are only a few hundred examples that have any supporting evidence. There are good scientific reasons to believe that most of the detected transcripts are junk RNA produced as the result of accidental, spurious, transcription.
There are about 20,000 protein-coding genes in the human genome. I think it's unlikely that there are more than a few thousand genes for functional RNAs for a total of less than 25,000 genes.
Here's one of the papers I found.
Guil, S. and Esteller, M. (2015) RNA–RNA interactions in gene regulation: the coding and noncoding players. Trends in Biochemical Sciences 40:248-256. [doi: 10.1016/j.tibs.2015.03.001]
Trends in Biochemical Sciences is a good journal and this is a review of the field by supposed experts. The authors are from the Department of Physiological Sciences II at the University of Barcelona School of Medicine in Barcelona, Catalonia, Spain. The senior author, Manel Esteller, has a Wikipedia entry [Manel Esteller].
Here's the first paragraph of the introduction.
There are more genes encoding regulatory RNAs than encoding proteins. This evidence, obtained in recent years from the sum of numerous post-genomic deep-sequencing studies, give a good clue of the gigantic step we have taken from the years of the central dogma: one gene gives rise to one RNA to produce one protein.
The first sentence is not true by any stretch of the imagination. The best that could be said is that there "may" be more genes for regulatory RNAs (> 20,000) but there's no strong consensus yet. Since the first sentence is an untruth, it follows that it is incorrect to say that the evidence supports such a claim.
It's also untrue to distort the real meaning of the Central Dogma of Molecular Biology, which never said that all genes have to encode proteins. The authors don't understand the history of their field in spite of the fact they are writing a review of that field.
Here's the problem. Are these scientists acting in good faith when they say such nonsense? Does acting in "good faith" require healthy criticism and critical thinking or is "honesty" the only criterion? The authors are clearly deluded about the controversy since they assume that it has been resolved in favor of their personal biases but they aren't lying. Can we distinguish between competent science and bad science based on such statements? Can we say that these scientists are incompetent or is that too harsh?
Furthermore, what ever happened to peer review? Isn't the system supposed to prevent such mistakes?
The Mysterious World of the Human Genome
by Frank Ryan
William Collins, an imprint of Harper Collins, London UK (2015)
ISBN 978-0-00-754906-1
This is just another "gosh, gee whiz" book on the amazing and revolutionary (not!) discoveries about the human genome. The title tells you what to expect: The Mysterious World of the Human Genome.
The author is Frank P. Ryan, a physician who was employed as an "Honorary Senior Lecturer" in the Department of Medical Education at the University of Sheffield (UK). He's a member of The Third Way group. You can read more about him at their website: Frank P. Ryan.
Last night's debate between Lawrence Krauss, Stephen Meyer, and Denis Lamoureux was very entertaining. I finally got to meet Stephen Meyer in person. (My photographer wasn't very good at focusing.)
There were some interesting exchanges during the debate. I want to talk about one of them.
Krauss tried to hammer Meyer on the "ID is not science" issue using quotes from a judge based on things said by lawyers in the Dover trial.1 Krauss tried to dismiss ID by saying that it never makes predictions but Meyer countered effectively by pointing out that ID predicts that most of our genome is functional and claiming that the prediction was confirmed by the ENCODE study.
The ID position is that Darwinists predicted that our genome would be full of junk while Intelligent Design Creationists predicted that most of our genome would be functional. ID was correct and Darwinism was wrong, according to this story.
Both Lawrence Krauss and Denis Lamoureux accepted the "fact" that ENCODE was right and most of the DNA in our genome has a function. Krauss was also hampered by his misunderstanding of evolution. It's obvious that he accepts the Richard Dawkins view of evolution so he tried to accommodate the ENCODE results by saying it's what you would expect of natural selection. This is the Richard Dawkins position.
Krauss tried to downplay the issue by saying that ID had not predicted what those functional parts of the genome would be doing but this was a weak rebuttal.
The facts are these ....
"Darwinists"—those who claim that natural selection is the only game in town—were opposed to the idea that most of our genome is junk. They still are.
Today, the majority of experts believe that most of our genome is junk in spite of the ENCODE publicity campaign from 2012.
The ENCODE Consortium has backed off it's original claim and now agrees that they misused the word "function." Some of them blame the media for distorting their position.
The ID "prediction" has been falsified.
A competent biologist would have known all this and could have challenged Meyer's statement. A biologist would have then demanded that Meyer explain how a genome that is 90% junk fits with Intelligent Design Creationism.
I talked to Denis Lamoureux after the debate to let him know that he was wrong about ENCODE and he was very gracious. I promised to send him more information. A genome full of junk DNA poses no threat to his version of Theistic Evolution.
Lawrence Krauss is an expert on cosmology but he's very weak on biology. I know it's common for physicists to think they are experts in everything but that's just not true. It was demonstrated in last night's debate.
1. This is a bad strategy. It's better to accept that ID proponents are doing science but just doing it very badly. Meyer ignored the issue of whether ID counted as science. He just presented the scientific case for ID and forced Krauss to respond to his "evidence."
Today's the day we find out "What's Behind It All?" The decision will be announced at the University of Toronto (Toronto, Ontario, Canada) by Lawrence Krauss when he educates the audience at Convocation Hall starting at 7 pm. Stephen Meyer (Intelligent Design Creationist) and Denis Lamoureux (Theistic Evolution Creationist) will also be there to learn the answer. (Spoiler Alert: the answer is "nothing.")
It's not too late to buy tickets. Email me if you want to join some of us for dinner before the event.
The event is being sponsored by Wycliffe College at the University of Toronto. This is an Anglican College that trains people to become Anglican Ministers (among other things). The college is the prime mover behind this series of events and it deserves a great deal of credit for the effort. Co-sponsors include the Centre for Inquiry, Canada and three Christian groups.
Those on the Darwinist, materialist, atheist side of the debate that we follow here aren't normally very good at listening and responding to scientific perspectives at variance from their own. They are much more interested in condemning and ridiculing -- which has got to be a poor strategy for them if they want to persuade anyone.
With that as the background, as we noted already, it's refreshing that arch-atheist cosmologist Lawrence Krauss has agreed to participate in a public conversation with Discovery Institute's Stephen Meyer, joined by theistic evolutionist Denis Lamoureux. That will be March 19 at the University of Toronto's Convocation Hall. We're looking forward to it -- and here's the even better news. You won't have to be in Toronto to enjoy the discussion. The event will stream live here at Evolution News.
I'm not a fan of TED talks. Comedian Will Stephen has figured them out and he gives a perfect example of everything that's wrong with a TED talk. Watch "How to sound smart in your TEDx Talk."
I was reading up on non-coding RNAs and came across this recent paper.
Bhartiya, D., and Scaria, V. (2016) Genomic variations in non-coding RNAs: Structure, function and regulation. Genomics 107:59-68. [doi: 10.1016/j.ygeno.2016.01.005]
Abstract: The last decade has seen tremendous improvements in the understanding of human variations and their association with human traits and diseases. The availability of high-resolution map of the human transcriptome and the discovery of a large number of non-protein coding RNA genes has created a paradigm shift in the understanding of functional variations in non-coding RNAs. Several groups in recent years have reported functional variations and trait or disease associated variations mapping to non-coding RNAs including microRNAs, small nucleolar RNAs and long non-coding RNAs. The understanding of the functional consequences of variations in non-coding RNAs has been largely restricted by the limitations in understanding the functionalities of the non-coding RNAs. In this short review, we outline the current state-of-the-art of the field with emphasis on providing a conceptual outline as on how variations could modulate changes in the sequence, structure, and thereby the functionality of non-coding RNAs.
The University of Toronto publicity department is making a big deal of Rachel Harding. She's a post-doc in the Structural Genomics Consortium (SGC). She works on Huntington's disease.
Faculty of Medicine researcher Rachel Harding will be the first known biomedical researcher to welcome the world to review her lab notes in real time. The post-doctoral fellow with U of T’s Structural Genomics Consortium (SGC) is also explaining her findings to the general public through her blog. She hopes her open approach will accelerate research into Huntington’s disease.
“This should drive the process faster than working alone,” Harding says. “By sharing my notes, I hope that other scientists will critique my work, collaborate and share data in the early stages of research.” Her research at SGC is funded by CHDI Foundation, a non-profit drug-development organization exclusively dedicated to Huntington’s disease. Both organizations aim to accelerate research by making it open and collaborative.
Her approach is intended to leverage the experience of a community of scientists. Individual researchers often still work in relative isolation and then publish only their positive discoveries, usually years after the experiments were actually done. Thus, scientists often pursue similar ideas in parallel and miss many opportunities to learn from each other’s mistakes.
She has started by publishing raw data and play-by-play details of her first effort on the CERN open digital repository Zenodo. She also posts regular updates on her blog Lab Scribbles, where she includes an experimental summary written in lay terms.
It's been over 35 years since I first starting thinking and talking about electronic (computerized) lab notes1 and it's been over twenty years since I first heard discussions about putting them online. I seriously doubt that Rachel Harding is the first biomedical researcher to put lab notes on the web. I'm also very skeptical about her keeping up the practice for very long.
Not only is it boring and tedious to write your lab notes in a word processing program but it's kinda embarrassing to post everything you do in the lab. At least it would have been for me. I made lots of mistakes and there are lots of R-rated words and phrases in my notes.
Let's keep an eye on this experiments to see how it goes. So far there are four items on the Zenodo website. The first is a Word document containing a few brief notes from Jan. 6, 7, 9, 11 and 25. There are brief notes posted on Feb. 6 and two on Feb. 11. I hope this isn't the extent of her lab notes.
The blog is Lab Scribbles. There are a few posts. It's interesting but I'm not sure anyone is going to read it even if you're interested in Huntington's.
Has anyone else experimented with open lab notes?
1. I still have a few floppy disks with those attempts from about 1981. Unfortunately, I don't have a machine that can read them.
The first drafts of the human genome sequence were published in 2001. There was still work to do on "finishing" the sequence but a lot of the International Human Genome Project (IHGP) team shifted to work on the mouse genome. The FANTOM Consortium and the RIKEN Genome Exploration Groups (I and II) published an analysis of mouse transcripts in December 2002.
Okazaki, Y., Furuno, M., Kasukawa, T., Adachi, J., Bono, H., Kondo, S., Nikaido, I., Osato, N., Saito, R., Suzuki, H. et al. (2002) Analysis of the mouse transcriptome based on functional annotation of 60,770 full-length cDNAs. Nature, 420:563-573. [doi: 10.1038/nature01266]
Only a small proportion of the mouse genome is transcribed into mature messenger RNA transcripts. There is an international collaborative effort to identify all full-length mRNA transcripts from the mouse, and to ensure that each is represented in a physical collection of clones. Here we report the manual annotation of 60,770 full-length mouse complementary DNA sequences. These are clustered into 33,409 ‘transcriptional units’, contributing 90.1% of a newly established mouse transcriptome database. Of these transcriptional units, 4,258 are new protein-coding and 11,665 are new non-coding messages, indicating that non-coding RNA is a major component of the transcriptome. 41% of all transcriptional units showed evidence of alternative splicing. In protein-coding transcripts, 79% of splice variations altered the protein product. Whole-transcriptome analyses resulted in the identification of 2,431 sense–antisense pairs. The present work, completely supported by physical clones, provides the most comprehensive survey of a mammalian transcriptome so far, and is a valuable resource for functional genomics.
Postgenomics is a compendium of twelve scholarly articles by philosophers and sociologists who write about the implication of the human genome sequence and subsequent work on interpreting the results. The volume is edited by Sarah Richardson, a professor in Social Sciences (History of Science) at Harvard University (Boston, Massachusetts, USA), and by Hallam Stevens, a professor of History at Nanyang Technology University in Singapore (Singapore).
The first essay is by Stevens and Richardson and it outlines the goal of the book.
One of the biggest problems with the Intelligent Design Creationist movement is their attempt to corral all creationist under the same big tent. This leads to a situation where Young Earth Creationists are afforded the same level of respect as those who accept common descent and an ancient Earth.
It means that dissent within the ID community is strongly suppressed in order to maintain the illusion that they all agree on the basics (i.e. goddidit). This leads to ridiculous situations where Young Earth Creationists defend Stephen Meyer's attack on the Cambrian explosion in Darwin's Doubt when they don't even believe that the Earth is 500 million years old!
There's no consistency in the arguments from ID proponents so it's almost impossible to have a serious discussion of the science behind their claims. I've criticized ID proponents for not applying critical thinking to their own movement. They almost never dispute each other's ideas for fear that it would weaken their movement.
That fear is justified, but what they fail to realize is that the movement doesn't deserve any respect at all if they don't apply the same standards to their own views that they demand of others.
To their credit, a few members of the movement have started to change this long-standing attempt to silence dissent within the movement. I think they realize that the respect they crave will only come from kicking a few people out of the tent.
One of those people is Vincent Torley. He has posted an excellent discussion of Denton's structuralist views on Uncommon Descent: Denton vs. Moran on structuralism. I don't agree with everything Torley says but I congratulate him for his courage in thinking critically about Michael Denton's position.
It will be interesting to see if the Intelligent Design Creationist movement can deal with critical thinking. I'm watching the comments on the blog post.
Here's a video where Michael Denton describes his view of biology. The main point is that he cannot think of a way for evolution to produce the "hierarchy of nature." Therefore goddidit there must be some other explanation.
Darwinism, honestly regarded, should lead you to expect not an ordered, increasingly inclusive hierarchy of life but more like a disordered...smear of diversity. Such expectations are frustrated by reality. As biologist Michael Denton explains, life presents itself as a tiered formation marked by novelties or homologs. These taxa-defining novelties, such as the pentadactyl limb, are not lead up to by a series of forms increasingly like the final version.
That's strike one. Worse for Darwinism, it's typically the case that there is no way even to imagine how the novelty could be lead up to in such a manner. Strike two. Watch and enjoy.
Has a scientific explaination of the universe replaced the need for God as cause of its origins? Could life on our planet exist apart from divine intervention? Is there evidence for a designer?
On March 19th, three big thinkers, well-known in their various fields, will be together for the first time, on the stage at the University of Toronto’s Convocation Hall discussing God, science and the universe:
Lawrence M. Krauss World-renowned Theoretical Physicist
Stephen C. Meyer Cambridge educated author and intelligent design advocate
Denis O. Lamoureux Science and Religion professor from the University of Alberta
Questions like these will be posed to the panel:
How did the universe originate?
Does God play any role in the cosmos?
What is the relationship between science and religion?
You are invited to live-stream this event via YouTube at your venue free of charge. Once you register as an event host, Wycliffe College and our partners will be happy to provide you with promotional and follow-up material to help make your event a success.

Join thousands in Toronto and around the globe to take part in this rare and exciting opportunity.
Most of you are familiar with the long-term evolution experiment (LTEE) run by Richard Lenski. One of the cultures in that experiment evolved the ability to use citrate as a carbon source. Normally, E. coli cannot use this carbon source under aerobic conditions but the new strain not only utilizes citrate but can grow in cultures where citrate is the only source of organic carbon.
