I Prefer People Who Sign their Names to Comments and Blogs

 
Given a choice between anonymous bloggers (and commenters) and those who sign their real names, I prefer to deal with those who use their real names. In part, this is because I admire their willingness to stand behind what they say regardless of the possible consequences. I do understand that it's easy for a tenured Professor to say this but I've never hidden behind anonymity even when I was an undergraduate, a graduate student, a postdoc, or an untenured Professor.

Greg Laden discusses anonymous bloggers in Some of my best friends are pseudonymous bloggers. I pretty much agree with his position. His posting is well worth reading.

I also agree with his stance on arguing from authority. In the real world, it makes a difference if someone is someone is putting forth an argument based on years of experience in the field or not. Nobody has time to evaluate all of the facts on every issue. We have to learn who we can trust and who we can't. The connection between this and anonymous blogging is obvious.

Please do not interpret this as a blanket recommendation to trust everyone in a position of authority. Similarly, I'm well aware of the fact that non-experts often make insightful contributions to a debate. The issue is much more complex than that. We don't need to list all the exceptions to the general principle that wisdom and experience usually count for something.

Evolutionary Teapot

 
There's an exhibit of china and pottery inside the Legion of Honor museum in San Francisco. One of the items that caught the attention of Leslie is a funny looking teapot.

The teapot itself isn't that unusual but there's an inscription on the bottom that refers to evolution. Apparently, there was a bit of hysteria and over-reaction to Darwin's ideas in the 1880's and this teapot pokes fun at that era.




Legion of Honor: San Francisco

 
Last Sunday we visited the Legion of Honor art museum in San Francisco. We went specifically to see the Annie Leibovitz: A Photographer’s Life, 1990–2005 exhibit but there were lots of other wonderful sights to see. The building is a 3/4 scale copy of the Palais de la Légion d’Honneur in Paris.

There are two works of art in the main courtyard. The most impressive is a casting of Rodin's Thinker, which I interpret to be an icon for rationalism and a warning to creationists. The second is clearly an impressionist view of the Flying Spaghetti Monster





Evolution: 24 myths and misconceptions

 
If you think you understand it, you don't know nearly enough about it.
New Scientist has just published an excellent series of articles on evolution [Evolution: 24 myths and misconceptions]. These are some of the best explanations of evolution that I've ever seen in a popular magazine. Thus, it's all the more tragic that they spoil it all by putting a false picture of evolution (right) on the website.

Shared misconceptions:

Everything is an adaptation produced by natural selection
We tend to assume that all characteristics of plants and animals are adaptations that have arisen through natural selection. Many are neither adaptations nor the result of selection at all.
Natural selection is the only means of evolution
Much change is due to random genetic drift rather than positive selection. It could be called the survival of the luckiest.
Natural selection leads to ever-greater complexity
In fact, natural selection often leads to ever greater simplicity. And, in many cases, complexity may initially arise when selection is weak or absent.
Evolution produces creatures perfectly adapted to their environment
You don't have to be perfectly adapted to survive, you just have to be as well adapted as your competitors. The apparent perfection of plants and animals may be more a reflection of our poor imaginations than of reality.
Evolution always promotes the survival of species
The phrase "survival of fittest" is widely misunderstood (see 'Survival of the fittest' justifies everyone for themselves). Many wrongly assume it means that evolution always increases the chances of a species surviving.

Evolution sometimes results in individuals or populations becoming less fit and may occasionally even lead to extinction.
It doesn't matter if people do not understand evolution
At an individual level, it might not matter much. However, any modern society which bases major decisions on superstition rather than reality is heading for disaster
"Survival of the fittest" justifies "everyone for themselves"
The "fittest" can be the most loving and selfless, not the most aggressive and violent. In any case, what happens in nature does not justify people behaving in the same way
Evolution is limitlessly creative
It might seem like there is no end to nature's inventiveness but there are some features that could probably never evolve, at least on Earth.
Evolution cannot explain traits such as homosexuality
There are numerous evolutionary mechanisms that might explain homosexual behaviour, which is common in many species of animals.
Creationism provides a coherent alternative to evolution
The only thing that creationists agree on is that they don't like evolution. Even Genesis gives two contradictory accounts of creation.

Creationist myths:

Evolution must be wrong because the Bible is inerrant
This argument is undermined by the hundreds of errors and inaccuracies and contradictions found in Bible. It is anything but "inerrant".
Accepting evolution undermines morality
Actually people in more secular countries appear to behave more morally. And even if this claim was true, that would not alter the facts or justify their suppression.
Evolutionary theory leads to racism and genocide
Darwin's ideas have been invoked as justification for all sorts of policies, including some very unpleasant ones. But evolutionary theory is a descriptive science. It cannot tell us what is right and wrong.
Religion and evolution are incompatible
There are various ways in which the known facts about evolution can be reconciled with theistic religions. Some of these ways might be illogical and irrational, but they are no more illogical and irrational than other aspects of religions.
Half a wing is no use to anyone
Just as objects designed for one purpose can be used for another, so genes, structures and behaviours that evolve for one purpose become adapted to do another.
Evolutionary science is not predictive
It might not be possible to predict exactly what life will look like in a billion years but what counts are the predictions that can be made.
Evolution cannot be disproved so is not science
There are all sorts of findings and experiments that could have falsified evolution. In the century-and-a-half since Darwin published his theory, not one has.
Evolution is just so unlikely to produce complex life forms
By weeding out harmful mutations and assembling beneficial ones, natural selection acts like an "improbability drive" that can, given enough time, produce results that appear utterly impossible at first glance.
Evolution is an entirely random process
No and yes. Natural selection is a rigorous testing process that filters out what works from what doesn’t, driving organisms to evolve in particular directions. However, chance events play a big role too.
Mutations can only destroy information, not create it
Biologists are uncovering thousands of examples of how mutations lead to new traits and even new species. This claim not only flies in the face of the evidence, it is also a logical impossibility.
Darwin is the ultimate authority on evolution
Modern evolutionary theory is built on some - but not all - of Darwin's ideas, but has gone far beyond them.
The bacterial flagellum is irreducibly complex
Actually, flagella vary widely from one species to another, and some of the components can perform useful functions by themselves. They are anything but irreducibly complex.
Yet more creationist misconceptions
Evolution is just a theory: Yes it is, like Einstein's theory of special relativity. By theory, scientists mean an explanation backed by evidence. What creationists mean is that evolution is just a hypothesis, unsupported by evidence - which it is not. Evolution is a fact as well a theory.
Evolution violates the second law of thermodynamics
The second law of thermodynamics states that entropy, a measure of randomness, cannot decrease in a closed system. Our planet is not a closed system.

Tangled Bank #103

 
The latest issue of Tangled Bank is #103. It's hosted at rENNISance woman on the Nature network [The 103rd edition of the Tangled Bank].
Hello from Vancouver! I blog about current genetics, genomics, virology and evolution research. I'll also include posts about grant writing and any other ideas that take my fancy. Don't be shy - leave a comment and start a conversation!


If you want to submit an article to Tangled Bank send an email message to host@tangledbank.net. Be sure to include the words "Tangled Bank" in the subject line. Remember that this carnival only accepts one submission per week from each blogger. For some of you that's going to be a serious problem. You have to pick your best article on biology.

We Beat the Scientologists!

 
The good news is that atheists are no longer in last place! The bad news is that we have a long way to go to catch up with the Methodists.

EXPELLED: The Movie

 
This is a slick trailer for the movie Expelled: No Intelligence Allowed (irony alert!). Unfortunately, the contents of the movie won't measure up to the pre-release hype. Check out EXPELLED EXPOSED for a detailed rebuttal of the claims made in the movie.




A Slight Error

 

John Wilkins posted a brief note about a German school kid who "corrected" NASA's calculation of the probability of an asteroid hitting the Earth.

You need to read the comments to fully appreciate the irony of the title Oops, a slight error never killed anyone. (Sorry, John, I couldn't resist.)

What's Wrong with this Tree?

 
Ryan Gregory has published a wonderful article in Evolution: Education & Outreach (Gregory, 2008). The article is about understanding evolutionary trees—a subject we all need to pay attention to because there are so many conceptual pits into which we might tumble. You can read the complete article by clicking on the link below or you can read a short answer to the question on his blog Genomicron [Phylogenetic fallacies: "branching from a main line"].

Scandal at Tim Hortons

 
Every year at this time Tim Hortons runs a promotion called "Roll-up-the-rim." The idea is that you roll up the rim of the paper cup to reveal a prize. There are even special tools to make rolling up the rim easier [Roll Up the Rim]. (As you can see in the photos, you usually get to lose in two different languages.)

This year I only won a single free coffee whereas in previous years I won several cups and several free donuts. (In 1993 I won a stereo system.) I attributed this to bad luck.

Maybe not, according the Globe and Mail. There are lots of customers who think their wins are below the levels of previous years [Coffee junkies say it's a lean 'Roll Up the Rim' season]. Tim Hortons says your chances of winning should be one in nine. According to the article in the Globe and Mail, even Stuart McLean was disappointed that his crew didn't win more often.
For five of the eight weeks that Tim Hortons ran the promotion, CBC host Stuart McLean and his 12-member tour bus drove from Fort St. John, B.C., to Fargo, N.D., perhaps braking for more Hortons outlets than any other vehicle on the road during that period.

“We had logged about 8,000 kilometres on the Vinyl Cafe tour bus,” Mr. McLean, who doesn't drink coffee, later reflected on his show. “[We] made some new friends and rolled up enough rims to make you wonder if anyone ever wins anything.”
This is getting serious. Tim Hortons should not be making Stuart McLean upset [The Vinyl Cafe]. Before you know it, there will be a story about Dave and Morely at Tim Hortons and it won't be pretty watching two Canadian icons duke it out.

Oops! Somebody didn't get the message.

 
A group of scientists have published a series of articles about errors and inconsistencies in Al Gore's An Inconvenient Truth [Scientists debate the accuracy of Al Gore's documentary 'An Inconvenient Truth'].
There is no question that Al Gore’s 2006 documentary An Inconvenient Truth is a powerful example of how scientific knowledge can be communicated to a lay audience. What is up for debate is whether it accurately presents the scientific argument that global warming is caused by human activities. Climate change experts express their opinions on the scientific validity of the film’s claims in articles just published online in Springer’s journal, GeoJournal.
I guess they didn't get the message from Mooney and Nisbet. You see, when you develop a spin on climate change every scientist is supposed to stick to the script. You can't have freelancers running off and criticizing the frame.

This is exactly the problem with the concept of framing. Nisbet and Mooney just don't get it. There will always be scientists who disagree with the message being framed and it just not possible to shut them up. That's the exact opposite of what science is all about.

Happy 70th Bruce!

 
Last night was the gala 70th birthday party for Bruce Alberts at the Metropolitan Club in San Francisco. Here's Bruce with his first three graduate students; Glenn Herrick (right), Keith Yamamoto (left), and me (looking up).
