Warnemünde and Rostock
Yesterday our boat stopped at the habor in Warnemünde, Germany. There was a lot of activity of the quay in Warnemünde because a number of tall ships were in the harbor.
We took the train to the medieval town of Rostock—a key port in the Hansiatic League (Hansa=guilds). The architecture was similar to that in other leading cities of the Hansiatic League, notably Bruges.

Cruising
We've been on this boat for three days and we'll be on it for another 8 days as we cruise the Baltic Sea. Internet access costs 70 cents ($0.75 US) per minute so posts will be short and infrequent.

Carnival of Evolution #62: The Whig History
When it comes to the history of evolutionary theory, a whiggish image could look something like [the figure below]
I leave it to the readers to come up with a female version (including, for example, Maria Sibylla Merian, Rosalind Franklin, Barbara McClintock, Christiane Nüsslein-Volhard).
Arranging July's posts that I found interesting or entertaining as well as the few submitted by others according to a Whig history of evolutionary theory in the following is purely ornamental and does, of course, not imply any whiggishness on the side of the contributors.

Carnival of Evolution #61: Crustie Lovin; Edition
Hello, and welcome to the Carnival of Evolution #61. For this edition, I’ve chosen to celebrate what I perceive as an inexplicably underappreciated group of animals: the Crustacea. Of the major arthropod groups, I notice that crustaceans often get the short end of the stick. Everyone can name insects and recognise spiders, but besides seafood, crustaceans seem to be a question mark with most people. Insects and spiders have movies and songs written about them; crabs are the logo for cancer, the vernacular name for an STD, and they are an astrological sign.
Insulting. Crustaceans are awesome. There may be over a million insect species, but crustaceans take the cake when it comes to disparity, or morphological diversity, a measure in which no other taxon can match them.

Dear Denyse, Stop Digging
Further to Cornelius Hunter’s “Evolutionist: We do not promote any ‘spiritual ideologies,’” (in which he recounts that recent findings about RNA structure conservation suggest that even more of the mammalian genome is functional than supposed, hence there is less “junk DNA”:
I’ve never clearly understood Darwin’s fans attachment to junk DNA. It makes a good “anti-God” statement, as long as you are certain that the stuff is not and never could be any use. But that is precisely what is now widely contested. And it was a trap they need not have fallen into.
But a simple illustration will show that even if most of the information in DNA were never used, it would still be valuable. Let us say I have a directory of members of a club I belong to. I never use most of the phone numbers. Many numbers may never be used by anyone.
Does lack of use make that proportion of the directory junk?

Goodbye Dumpster
Jerry Coyne posted this video and I thought it was so funny I just had to put it on my website blog.
What Would Jerry Coyne, Daniel Dennett, and Richard Dawkins Do at Ball State University?
I'm trying to understand how the rules announced by President Jo Ann Gora would work in practice.
Let's think about how they might affect three prominent atheists. Jerry Coyne is an evolutionary biology professor at the University of Chicago. He is a prominent atheist and he defends the position that science and religion are not compatible. He does not have to adhere to the Ball State University rules because the University of Chicago is a private school.
Daniel Dennett is a philosopher at Tufts University (private). He is a prominent atheist and no friend of religion.
Richard Dawkins was a professor and evolutionary biologist at Oxford University in the UK. He did not have to worry about following the Ball State University rules because they don't apply outside of the USA.
Let's imagine that all three became professors at Ball State University. They would have to pay attention to the rules outlined by President Jo Ann Gora. Here are the relevant passages from her recent message.
Most professors have graduate students. They do not hide their opinions from their graduate students. Nor do they hide them from their colleagues or the administrators in their university.
These professors aren't shy about expressing their points of view on blogs, twitter, Facebook, newspapers and just any other means of communication.
Now let's imagine that they are teaching an undergraduate course about atheism and religion in a humanities department at Ball State University. How is that supposed to work? Are they supposed to go out of their way to avoid "privileging one view as more legitimate than others"? And if so, are any of the students going to be fooled? They can all access the internet.
It's clearly a ridiculous rule unless it also applies outside of the classroom. Does it mean that professors at a public university must avoid criticizing religion at all times?

Creation science, intelligent design, and other worldviews that focus on speculation regarding the origins of life represent another important and relevant form of human inquiry that is appropriately studied in literature and social science courses. Such study, however, must include a diversity of worldviews representing a variety of religious and philosophical perspectives and must avoid privileging one view as more legitimate than others.All three professors have written extensively about religion and their views are widely known. They attend conferences and give public lectures. They do not pull any punches when they talk about the evils of religion. Nobody would ever say that they go out of their way to avoid endorsing one perspective over another. Academics have opinions and they are not afraid to express them.
As a public university, we have a constitutional obligation to maintain a clear separation between church and state. It is imperative that even when religious ideas are appropriately taught in humanities and social science courses, they must be discussed in comparison to each other, with no endorsement of one perspective over another.
Most professors have graduate students. They do not hide their opinions from their graduate students. Nor do they hide them from their colleagues or the administrators in their university.

The Junk DNA Controversy: John Mattick Defends Design
The failure to recognize the implications of the non-coding DNA will go down I think as the biggest mistakes in the history of molecular biology.
John Mattick
abc AustraliaJohn Mattick has just published a paper dealing with the controversy over the ENCODE results and junk DNA. As you might imagine, Mattick defends the idea that most of our genome is functional. He attempts to explain why most of the critics are wrong.
The title of the paper is "The extent of functionality in the human genome" (Mattick and Dinger, 2013). It's published in the HUGO Journal. Recall that HUGO (Human Genome Organization) gave Mattick a prestigious award for his contributions to genome research. (See The Dark Matter Rises for a discussion of these contributions.)
UPDATE: Mike White also discusses this paper at: Having your cake and eating it: more arguments over human genome function.
Mattick's paper begins by mentioning three of the papers that were critical of ENCODE results: Dan Graur's paper (Graur et al. 2013), Ford Doolittle's paper (Doolittle, 2013), and the paper by Niu and Jiang (2013).
He begins by addressing one of Dan Graur's points about conservation.

The Dark Matter Rises
John Mattick publishes lots of papers. Most of them are directed toward proving that almost all of the human genome is functional. I want to remind you of some of the things that John Mattick has said in the past so you'll be prepared to appreciate my next post [The Junk DNA Controversy: John Mattick Defends Design].
Mattick believes that the Central Dogma means DNA makes RNA makes protein. He believes that scientists in the past took this very literally and discounted the importance of RNA. According to Mattick, scientists in the past believed that genes were the only functional part of the genome and that all genes encoded proteins.
If that sounds familiar it's because there are many IDiots who make the same false claim. Like Mattick, they don't understand the Central Dogma of Molecular Biology and they don't understand the history that they are distorting.
Mattick believes that there is a correlation between the amount of noncoding DNA in a genome and the complexity of the organism. He thinks that the noncoding DNA is responsible for making tons of regulatory RNAs and for regulating expression of the genes. This belief led him to publish a famous figure (left) in Scientific American.Mattick has many followers. So many, in fact, that the Human Genome Organization (HUGO) recently gave him an award for his contributions to the study of the human genome. Here's the citation.
Theme
Genomes
& Junk DNA
The Award Reviewing Committee commented that Professor Mattick’s “work on long non-coding RNA has dramatically changed our concept of 95% of our genome”, and that he has been a “true visionary in his field; he has demonstrated an extraordinary degree of perseverance and ingenuity in gradually proving his hypothesis over the course of 18 years.”Let's see what this "true visionary" is saying this year. The first paper is "The dark matter rises: the expanding world of regulatory RNAs" (Clark et al., 2013). Here's the abstract ...
The ability to sequence genomes and characterize their products has begun to reveal the central role for regulatory RNAs in biology, especially in complex organisms. It is now evident that the human genome contains not only protein-coding genes, but also tens of thousands of non–protein coding genes that express small and long ncRNAs (non-coding RNAs). Rapid progress in characterizing these ncRNAs has identified a diverse range of subclasses, which vary widely in size, sequence and mechanism-of-action, but share a common functional theme of regulating gene expression. ncRNAs play a crucial role in many cellular pathways, including the differentiation and development of cells and organs and, when mis-regulated, in a number of diseases. Increasing evidence suggests that these RNAs are a major area of evolutionary innovation and play an important role in determining phenotypic diversity in animals.This is his main theme. Mattick believes that a large percentage of the human genome is devoted to making regulatory RNAs that control development. He believes that the evolution of this complex regulatory network is responsible for the creation of complex organisms like humans, which, incidentally, are the pinnicle of evolution according to the figure shown above.
The second paper I want to highlight focuses on a slightly different theme. It's title is "Understanding the regulatory and transcriptional complexity of the genome through structure." (Mercer and Mattick, 2013). In this paper he emphasizes the role of noncoding DNA in creating a complicated three-dimensional chromatin structure within the nucleus. This structure is important in regulating gene expression in complex organisms. Here's the abstract ...
An expansive functionality and complexity has been ascribed to the majority of the human genome that was unanticipated at the outset of the draft sequence and assembly a decade ago. We are now faced with the challenge of integrating and interpreting this complexity in order to achieve a coherent view of genome biology. We argue that the linear representation of the genome exacerbates this complexity and an understanding of its three-dimensional structure is central to interpreting the regulatory and transcriptional architecture of the genome. Chromatin conformation capture techniques and high-resolution microscopy have afforded an emergent global view of genome structure within the nucleus. Chromosomes fold into complex, territorialized three-dimensional domains in concert with specialized subnuclear bodies that harbor concentrations of transcription and splicing machinery. The signature of these folds is retained within the layered regulatory landscapes annotated by chromatin immunoprecipitation, and we propose that genome contacts are reflected in the organization and expression of interweaved networks of overlapping coding and noncoding transcripts. This pervasive impact of genome structure favors a preeminent role for the nucleoskeleton and RNA in regulating gene expression by organizing these folds and contacts. Accordingly, we propose that the local and global three-dimensional structure of the genome provides a consistent, integrated, and intuitive framework for interpreting and understanding the regulatory and transcriptional complexity of the human genome.Other posts about John Mattick.

Teach the Controversy
There doesn't seem to be much of a problem with this idea in Canada but in the United States there is a lot of opposition to the idea. Check out Jerry Coyne's recent post to see what I mean: Once again Larry Moran decries legal battles against creationism.
Let's focus on a specific example. First, we need some background. Many state legislatures in the USA have seriously considered, or passed, so-called Academic Freedom bills. On the surface, these bill look innocuous. They are designed to promote critical thinking in state schools. Part of that process involves challenging and debating controversial science topics. We all know, however, that the real propose is to allow teachers to challenge evolution by teaching alternative "theories" (i.e. creationism).
Why not try a different strategy? Here's the text of the Louisiana Science Education Act
Section 1. R.S. 17:285.1 is hereby enacted to read as follows:Why not find a few high school teachers and support them in an effort to adhere to the law by teaching critical thinking? They could choose a couple of examples of controversial ideas in Louisiana society and address them head-on in their science classes. I suggest two popular ideas that challenge the textbook description of evolution.
§285.1. Science education; development of critical thinking skills
A. This Section shall be known and may be cited as the "Louisiana Science Education Act."
B.(1) The State Board of Elementary and Secondary Education, upon request of a city, parish, or other local public school board, shall allow and assist teachers, principals, and other school administrators to create and foster an environment within public elementary and secondary schools that promotes critical thinking skills, logical analysis, and open and objective discussion of scientific theories being studied including, but not limited to, evolution, the origins of life, global warming, and human cloning.
(2) Such assistance shall include support and guidance for teachers regarding effective ways to help students understand, analyze, critique, and objectively review scientific theories being studied, including those enumerated in Paragraph (1) of this Subsection.
C. A teacher shall teach the material presented in the standard textbook supplied by the school system and thereafter may use supplemental textbooks and other instructional materials to help students understand, analyze, critique, and review scientific theories in an objective manner, as permitted by the city, parish, or other local public school board unless otherwise prohibited by the State Board of Elementary and Secondary Education.
D. This Section shall not be construed to promote any religious doctrine, promote discrimination for or against a particular set of religious beliefs, or promote discrimination for or against religion or nonreligion.
E. The State Board of Elementary and Secondary Education and each city, parish, or other local public school board shall adopt and promulgate the rules and regulations necessary to implement the provisions of this Section prior to the beginning of the 2008-2009 school year.
- The universe was created only 6000 years ago.
- Humans were created separately from apes.
The evidence and lesson plans could be posted online and evolution supporters could publicize the lessons and show how effective it is to teach critical thinking by debunking some popular myths. At first there may be only a few teachers willing to take a stand but hopefully those numbers would grow as more and more teachers realize that they will have solid support from the scientific community.
Even students who aren't in the designated classrooms will become aware of the dangers of teaching the controversy. Maybe state politicians will have second thoughts. They might try and silence the teachers but that would be difficult given that the law specifically encourages teachers to teach the controversy. It would be interesting if they tried to stop the lessons by claiming that those ideas were religious and debunking them was an example of discrimination against religion.
I submit that this might be a far more effective strategy for changing people's minds than fighting another court case.
Please don't argue that those two ideas aren't "science" and should never be discussed in a science classroom. Those ideas are attacks on science and they are certainly part of the controversy about evolution—at least in Louisiana. Moreover, those are exactly the sorts of things that the politicians had in mind when they voted overwhelmingly for this law back in 2008. There's no better way to teach critical thinking than to use specific examples of bad science to show students how to recognize the difference between good science and bad science.
Many people think that teaching the controversy means bringing stupid ideas into the classroom and treating them as if they were respectable alternatives to real science. That's a false assumption. You can just as easily bring stupid ideas into the classroom and teach students why they are stupid ideas. That would be a good thing.
