Ask a stupid question ... can anyone guess the answer?

I just love the IDiots. They never cease to amaze, and amuse, me. Here's the latest from David Klinghofer at: Intelligent Design as an Orange Flag.
The mention of ID seems to give many writers and commentators what they regard as a green light to blather on without taking a moment to grasp what they're writing about. Denouncing ID is one thing. Denouncing it without comprehending what the phrase refers to, which is amazingly common, is quite another.

I continue to find this amazing. What other subject, both controversial and somewhat recondite, seems to license apparently smart people to write and speak in such an uninformed way?
Gee, I wonder what other subject causes apparently smart people to behave like IDiots? What other subject gives people a green light to blather on when they don't have the slightest clue what they are talking about? Is there another subject that some people denounce without comprehending what it means? Hmmm .....

Can anyone think of such a subject?


Was Louis Agassiz better in the concrete?

Back in the nineteenth century (i.e. more than one hundred years ago) there was a biologist named Louis Agassiz who didn't like Darwin's radical ideas about evolution. Agassiz, a very famous professor at Harvard, thought that there were major gaps n the fossil record and he lamented the apparent lack of transitional fossils. What he was looking for were fossils of direct ancestors of modern species and not their close cousins.

Stephen Meyer thinks this old debate is still relevant today so he writes it up in Darwin's Doubt as if nobody in the past one hundred years ever thought of an explanation. It fooled Denyse O'Leary (not hard) so she blogged about it today [Louis Agassiz: The selective incompleteness of the fossil record].

This reminds me of a famous photograph of the statue of Louis Agassiz embedded upside down in the courtyard in front of the zoology building at Stanford University. The statue tumbled from its place above the entrance during the San Francisco earthquake of 1906.

According to legend, a passing scientist remarked that,
Louis Agassiz was great in the abstract but not in the concrete.1
Actually, it would be even better to say that Agassiz looks better in the concrete than in the abstract [see Agassiz in the Concrete and Persecution of Religious Scientists]. By the 1920s (earlier in Europe) Agassiz's reputation had been severely damaged by his willingness to let religious convictions dictate his science.2


1. The story is apocryphal (a polite word for "false"). The quotation has been attributed to several men, including the President of Stanford, but all have denied it. Nevertheless, it's too good a story to abandon just because it happens to be untrue!

2. Stephen Jay Gould held the Alexander Agassiz Professor of Zoology Chair at Harvard from 1982 until his death in 2002. Alexander Agassiz was Louis Agassiz's son. Alexander served as President of the National Academy of Sciences.

Monday's Molecule #225

Last week's molecule was EF-Tu (elongation factor-thermo unstable). EF-Tu binds to all tRNA molecules in the cell and helps position them in the A-site of the ribosome-mRNA complex during protein synthesis. Its release is coupled to GTP hydrolysis. Eukaryotes contain homologous proteins with different names (e.g. EF-1α). The winner was Jon Nuelle from Texas. The undergraduate winner was Ariel Gershon for the second week in a row.

Today's molecule (below) is an intermediate in a very important pathway that's only found in some species. This is one of those times when you need to supply the common name AND the correct scientific name that specifies the exact molecule shown in the figure.

Email your answer to me at: Monday's Molecule #225. I'll hold off posting your answers for at least 24 hours. The first one with the correct answer wins. I will only post the names of people with mostly correct answers to avoid embarrassment. The winner will be treated to a free lunch.

There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your email message.)

Carnival of Evolution #66: The Day of the Doctor

This month's Carnival of Evolution is hosted by none other than John Wilkins. He's a philosopher but don't let that put you off. He blogs at Evolving Thoughts although from time to time he threatens to stop blogging. Encourage John by visiting The Day of the Doctor of Evolution: CoE #66.

The "Doctor" in the title is a reference to Dr. Who. Apparently John watched the first episodes in 1963!! "Who" knew that he was even born in 1963?
I was eight years old in late November 1963. I didn’t pay much attention to the TV news – some guy had been shot or something, and I wasn’t to know that C. S. Lewis had died until much later – but I was instantly taken by the eerie sound of the opening music of a new show. Yes, it was the very first episode of Dr Who, in glorious monochrome! I was a Whovian from the beginning, before it was cool. I’m so hip…
If you can't name the blue thingy on the right then you probably never win trivia games.

If you want to host a Carnival of Evolution please contact Bjørn Østman. Bjørn is always looking for someone to host the Carnival of Evolution. He would prefer someone who has not hosted before but repeat hosts are more than welcome right now! Bjørn is threatening to name YOU as host even if you don't volunteer! Contact him at the Carnival of Evolution blog. You can send articles directly to him or you can submit your articles at Carnival of Evolution although you now have to register to post a submission. Please alert Bjørn or the upcoming host if you see an article that should be included in next month's. You don't have to be the author to nominate a post.

Elizabeth Pennisi writes about Richard Lenski's long-term evolution experiment

Elizabeth Pennisi has written about the long-term evolution experiment of Richard Lenski [The Man Who Bottled Evolution]. The experiment is in it's 25th year and it is entirely appropriate that Science magazine devotes several pages to describing the results. There have been some remarkable discoveries.

But I want to focus on a couple of things that Pennisi says in her article. There has also been a discussion on Panda's Thunb: Lenski’s experiment: 25 years and 58,000 generations. Pennisi writes ...
Lenski's humble E. coli have shown, among other things, how multiple small mutations can prepare the ground for a major change; how new species can arise and diverge; and that Gould was mistaken when he claimed that, given a second chance, evolution would likely take a completely different course. Most recently, the colonies have demonstrated that, contrary to what many biologists thought, evolution never comes to a stop, even in an unchanging environment.
Let's talk about two issues in that paragraph.
