A 2004 kerfuffle over pervasive transcription in the mouse genome

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.

When philosophers talk about genomes

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.

An intelligent Intelligent Design Creationist

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.

Michael Denton discusses the "hierarchy of nature"

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.

The Discovery Institute made the video. David Klinghoffer describes it on Evolution News & Views (sic): Conversations with Dr. Denton: The Hierarchy of Nature. Klinghoffer says,

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.

God, Science, and the Universe

Hosted by Wycliffe College at the University of Toronto (Toronto, Ontario, Canada): Religion and Society Series - God, Science and the Universe.

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.

As evidenced by our sponsors, this is an opportunity that spans the diverse interests and questions of the scientist, the scholar, the layperson, the young and the old, and the Atheist, Agnostic and Christian. Our goal is to be a catalyst in starting conversations around our country on issues of faith and their intersection with broader society.　

Join thousands in Toronto and around the globe to take part in this rare and exciting opportunity.

An Intelligent Design Creationist disputes the evolution of citrate utilization in the LTEE ... Lenski responds

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.

The pathway to this event is complex and requires multiple mutations [see On the unpredictability of evolution and potentiation in Lenski's long-term evolution experiment and Lenski's long-term evolution experiment: the evolution of bacteria that can use citrate as a carbon source].

Darwin's statue

A large statue of Charles Darwin was installed in the main foyer of the London's Natural History Museum in 1885—just a few years after Darwin's death. It was removed in 1927 and replaced by a statue of Richard Owen who was no fan of Darwin.

The museum came to its senses in 2009 and put the statue back in it's original position. (It had been in the cafeteria in the basement.) Read the story at: Moving Darwin.

Owen was the man who founded the museum and he was also known for his support of structuralism—the idea that basic body plans cannot be easily explained by evolution. Structuralism is the new buzzword among Intelligent Design Creationists. They don't understand the concept but they're certain it refutes evolution and supports goddidit.

Michael Denton is upset about the statue [see Conversations with Michael Denton: You Can Move the Statue if You Wish...]. Watch the video ...

Ignorance + "body plans" + misinformation (lies) + god-of-the-gaps = Intelligent Design Creationism

Watch Paul Nelson combine his lack of knowledge of evolution and evolutionary theory with misinformation (i.e. lies) and a little bit of false developmental biology then stir the pot with a large dose of god-of-the-gaps to produce a smooth argument that refutes evolution.

There's lots of other stuff going on in this talk. I was especially amused by the discussion of methodological naturalism at the end. Paul Nelson argues that science is blind to all the evidence of a creator because the "rule" of science is that it can't even consider that evidence.

I'll say one thing about this talk: it's very clever. It would take a book to show that Paul Nelson is wrong about everything and the explanations would be far too complicated for the average creationist. For them, it's easier to believe that Paul Nelson is telling them the truth and evolutionary biologists are too stupid to understand their own discipline.

Otangelo Grasso has posted a transcript of the talk. Thank-you Otangelo.

Happy birthday human genome sequence!

The draft sequences of the human genome were published fifteen years ago. The International Human Genome Project (IGHP) published its draft sequence in Nature on Feb. 15, 2001 (Lander et al., 2001) and Celera Genomics published its draft sequence in Science on Feb. 16, 2001 (Venter et al., 2001).¹

For me the timing was perfect since I was scheduled to give a Journal Club talk on March 16th and you could hardly ask for a better topic.

Justice Scalia's Misunderstanding

Antonin Gregory Scalia (March 11, 1936 – February 13, 2016), justice of the Supreme Court of the United States, died a few days ago. This creates a crisis in American politics because they have a strange set of Constitutional requirements guaranteed to maximize the probability of crises every time they need a new Supreme Court justice.

Scalia's death reminded me of the dissenting opinion in EDWARDS V. AGUILLARD (June 19, 1987). This was the case that invalidated Louisiana's "Balanced Treatment for Creation-Science and Evolution-Science Act." Stephen Jay Gould was puzzled by the dissenting opinion so he wrote a wonderful essay to explain Justice Scalia's Misunderstanding.

It's worth reading the entire essay but here's the conclusion,

Following this theme, Scalia presents his most confused statement in the written dissent:

Creation science, its proponents insist, no more must explain whence life came than evolution must explain whence came the inanimate materials from which it says life evolved. But even if that were not so, to posit a past creator is not to posit the eternal and personal God who is the object of religious veneration.

True indeed; one might be a creationist in some vernacular sense by maintaining a highly abstract and impersonal view of the creator. But Aristotle's unmoved mover is no more part of science than the Lord of Genesis. Science does not deal with questions of ultimate origins. We would object just as strongly if the Aristotelophiles of Delaware forced a law through the state legislature requiring that creation of each species ex nihilo by an unmoved mover be presented every time evolution is discussed in class. The difference is only historical circumstance, not the logic of argument The unmoved mover doesn't pack much political punch; fundamentalism ranks among our most potent irrationalisms.

Consider also, indeed especially, Scalia's false concept of science. He equates creation and evolution because creationists can't explain life's beginning, while evolutionists can't resolve the ultimate origin of the inorganic components that later aggregated to life. But this inability is the very heart of creationist logic and the central reason why their doctrine is not science, while science's inability to specify the ultimate origin of matter is irrelevant because we are not trying to do any such thing. We know that we can't, and we do not even consider such a question as part of science.

We understand Hutton's wisdom. We do not search for unattainable ultimates.

We define evolution, using Darwin's phrase, as "descent with modification" from prior living things. Our documentation of life's evolutionary tree records one of science's greatest triumphs, a profoundly liberating discovery on the oldest maxim that truth can make us free. We have made this discovery by recognizing what can be answered and what must be left alone. If Justice Scalia heeded our definitions and our practices, he would understand why creationism cannot qualify as science. He would also, by the way, sense the excitement of evolution and its evidence; no person of substance could be unmoved by something so interesting. Only Aristotle's creator may be so impassive.

Happy Valentine's Day!

Who was Saint Valentine? Nobody really knows very much about the Saints Valentine (there were about a dozen of them). The whole idea of romantic Valentine's day seems to have been invented by Geoffrey Chaucer¹ sometime around 1380.

It seems like people in England just wanted to enjoy a bit of debauchery fun on February 14th so they connected their frolics with a Roman Catholic saint in order to get the permission of the church! Pretty clever, eh?

Michael Denton discovers non-adaptive evolution ... attributes it to gods

Readers of this blog will know that I'm a fan of Evolution by Accident. I don't think that the history of life can be explained in strict Darwinian terms (i.e. natural selection) and I think that modern evolutionary theory includes Neutral Theory and a major role for random genetic drift.

This is the view of many modern evolutionary biologists. Their work and views have been reported frequently on Sandwalk over the past ten years but you can find it in all the evolutionary biology textbooks. I'm just the messenger here. It's evolutionary biologists who have made the case for non-adaptive evolution beginning long before The Spandrels of San Marco and the Panglossian Paradigm: A Critique of the Adaptationist Programme.

This is what a strawman looks like

This is another post about the stupidity of Intelligent Design Creationists. Stop reading if you don't need any more convincing.

Today is Darwin Day. It's the anniversary of the birth of Charles Darwin (Feb. 12, 1809 - April 19, 1882).

This is not a happy day for the Discovery Institute so they've put up a series of posts on Evolution News & Views (sic) to discredit Darwin and "Darwinism."

One of them is by the newly rejuvenated poster boy, Michael Denton: On Darwin Day, Darwinism Is Well Past Its "Sell By" Date. Here's the part I want you to see,

To understand the core weakness of the Darwinian worldview, it is important to understand what Darwinian natural selection requires. The process will work its magic, building up functional structures in organisms, only when two very strict conditions are met: First, the structure must be adaptive—that is, helpful to the organism in flourishing in its environment—and second, there must be a continuum of structures, functional all along the way, leading from an ancestor species to the descendent.

That is, the thing we are trying to explain must in some way help the creature survive, and between the creature and the creature's ancestor there must be a gradual change, each step of which is stable and enhances fitness, or success in reproduction.

Strictly speaking, that's a reasonable explanation of Darwinism as most evolutionary biologists understand it. But here's the problem. There aren't very many evolutionary biologists who are strict Darwinists these days even though there are many who tilt strongly in that direction.

Replaying life's tape

Intelligent Design Creationists are promoting a structuralist view of evolution [What is structuralism?]. The idea is that the history of life as we know it was largely preordained by the initial laws of physics and chemistry. According to this view, once life got under way it was inevitable that it would eventually evolve the way it did resulting in humans or something that closely resembles humans.

Structuralism is based on the idea of intrinsic forms that severely limit evolutionary pathways. These forms are constrained, and defined, by the physics of matter and energy. Some creationists like this idea because they believe that god created the universe and fine-tuned it for life. According to their faith, once the original laws of physics and chemistry were set up it was just a matter of time before humans evolved. These creationists can make their belief in a creator god compatible with evolution as they see it.

(Let's not forget that there are many structuralists who are legitimate scientists and some of them are atheists. Structuralism is not a creationist invention.)

The conflict between structuralists and others is brought into focus by Stephen Jay Gould writing in Wonderful Life.
