Carl Zimmer has never written a bad book, and he’s the author I usually recommend to non-scientists looking for a gentle but substantive introduction to ideas in biology. Now DarkSyde interviews Zimmer—this is one you’ll want to read.
OK, people, this is too cruel. I was gone all day yesterday, traveling to the Twin Cities for this Darwin Day event, and the site gets 37,000 visits. Are you all trying to tell me it’s better when I’m not around to clutter it up? If I take off for a week will traffic climb to Daily Kos-like proportions? (There was a link from fark that might actually explain the sudden surge.)
Anyway, I’ll give a quick summary of what I was up to yesterday.
I started with a 3 hour drive to Minneapolis, which was very exciting. High winds, blowing snow, near whiteout conditions. The weather was bad enough that they canceled public schools in the area.
When I got there, we set up in the Bell Museum auditorium. We had about 50 or 60 people show up.
The first talk was by Mark Borrello, a historian of biology, who gave a very good overview of Darwin’s life.
I’ve put a copy of my talk online (pardon the bloated format: blame Microsoft). Since I don’t use much text in my powerpoint presentations, I’ll give a rough overview of the content here. In my introduction, I pointed out a creationist accusation—that we’re “Darwinian fundamentalists” or “Darwinists”—and a claim—that there is no evidence for evolution. The point of my talk was to show that, much as we respect and admire Darwin as a founding father of an important scientific discipline, his theory has been expanded upon in ways he couldn’t even imagine, and that the addition of new information is an ongoing pursuit. There are major themes in evolutionary research—genetics, molecular biology, bioinformatics, genomics, evo-devo—that simply weren’t even on the horizon in Darwin’s day.
I gave a lightning quick, superficial overview of examples of new developments in evolution.
My conclusion was to show a pretty squid picture as an example of exotic beauty in nature, and explain that evolution is currently the only explanation that simultaneously explains the diversity and unity of life, and that it is the only explanation we have that is soundly based on the evidence.
The session closed with very short overviews of current research by three biologists in the ecology and evolutionary biology department: R. Ford Denison, Peter Tiffin, and Cynthia Weinig. They were very good, but I think the format was a bit much—after over two hours of talks, it was probably a mistake to put the most technically challenging talks at the very end, when the audience was exhausted.
Finally, I had a short planning discussion about Cafe Scientifique with the Bell Museum organizer, got in my car, cussed out rush hour traffic, got to western Minnesota to discover the roads were still invisible with blowing snow, and got home after a few exciting slides and twirls on powder-covered streets.
Today I’m planning to take it easy, read a bit, and attend the Prairie Home Companion show which will be broadcast live from UMM. You can find out more on the Prairie Home page, listen to it on your local station, and if you’ve got the real audio player, you can listen to it live between 5 and 7 pm Central time today. I doubt very much that he’ll say anything about evolutionary biology or science, but he may poke fun at my university, which is always entertaining.
This afternoon, I’ll be at the Bell Museum at the University of Minnesota, Twin Cities campus, celebrating the birth of Charles Darwin. Everyone is welcome, so come on down!
Events:
1:00P – Lecture by historian of biology Professor Mark Borrello, Department of Ecology, Evolution and Behavior, on the history of Darwin and evolutionary theory.2:00P – Lecture by biologist and blogger Professor P.Z. Myers, University of Minnesota—Morris, on evidence for evolution.
3:00P – Panel discussion of University of Minnesota evolutionary biologists on their cutting-edge research at the U of M titled “My Life’s Work in Three Minutes”. To be followed by a cake reception.
Charles Darwin achieved fame and infamy for his theory of evolution by natural selection, now the foundation underlying all biological sciences. Darwin Day is the anniversary of his birthday, whose exact date is February 12, 1809. The date is celebrated internationally.

Mmmmm-mmm. Cake. You can’t possibly miss this.
…and makes a total ass of himself.
In the interview, Mr. Deutsch said that Dr. Hansen had partisan ties “all the way up to the top of the Democratic Party,” and that he was “using those ties and using his media connections to push an agenda, a worst-case-scenario agenda of global warming.” He said that anyone who disagrees with Dr. Hansen “is labeled a censor and is demonized and vilified in the media — and the media of course is a willing accomplice here.”
And how does he know Hansen was a mere partisan flack peddling bad science? Because Deutsch almost has a bachelor’s degree in journalism from Texas A&M.
Well, I was going to put together more about this beautiful new basal tyrannosauroid from the Jurassic of China, Guanlong wucaii, but Carl Zimmer beat me to it. I’ll just show you that lovely crested skull, and below the fold, a picture of the fossil in situ, and let Carl do the hard work of explaining it all.
Here’s some very cool news: scientists have directly observed the evolution of a complex, polygenic, polyphenic trait by genetic assimilation and accommodation in the laboratory. This is important, because it is simultaneously yet another demonstration of the fact of evolution, and an exploration of mechanisms of evolution—showing that evolution is more sophisticated than changes in the coding sequences of individual genes spreading through a population, but is also a consequence of the accumulation of masked variation, synergistic interactions between different alleles and the environment, and perhaps most importantly, changes in gene regulation.
Unfortunately, it’s also an example of some extremely rarefied terminology that is very precisely used in genetic and developmental labs everywhere, but probably makes most people’s eyes glaze over and wonder what the fuss is all about. I’ll try to give a simple introduction to those peculiar words, and explain why the evolution of a polyphenic pigment pattern in a caterpillar is a fascinating and significant result.
Carl Zimmer has the lowdown on leeches. The article is right, and they really are beautiful animals—I had a tank full of them last semester (gone now, in a flurry of bloody student labs), and watching them undulate through the water was mesmerizing. They were almost as much fun to watch as my fish.
I just received my copy of the latest Seed, and although I feel a bit reluctant to say it because it may be interpreted as sucking up to the corporate masters who provide my bandwidth, it really is a very good science magazine—I’d be subscribing even if they weren’t sending it to me for free. Take a browse through it sometime, there’s a lot of the content available online.
Anyway, of course the first thing I turn to in the magazine is Chris Mooney’s article on Learning to speak science. It’s good and has some productive suggestions, and I agree with Mooney on 90% of what he says in it, but…
Argento tackles the growing man-squirrel problem…and incidentally mentions me, the apologist for man-squirrel research.
Last week, the opening convocation for Black History Month was given by Tyrone Hayes of UC Berkeley. I was impressed: he’s exceptionally personable, and despite the poor organization of his visit (UMM’s fault, entirely) and having to drive for hours through a small blizzard to get here from the airport, he was gracious and fun to talk with. He gave a phenomenally well-organized, lucid talk which managed to describe all the basics of his research in terms a lay audience, most of whom were not science majors of any kind, could comprehend. And as I learned, most of his work is done by undergraduates—he has an enviable research program fueled by entry level students working towards a bachelor’s degree. I am humbled.
I have to say that if you get an opportunity to hear Hayes speak, jump at it. It’s a model of good educational rhetoric. And hey, if you’re on a seminar committee somewhere, look into inviting him out…it will be worth your while.
The subject of his talk was atrazine. Atrazine is a heavily used pesticide in the United States—we hose our cornfields with the stuff around here, using it to control weeds and boost the productivity of our acreage by 1.2%. That may not sound like much, but over the entire midwest, that adds up to really big money, money that flows into the coffers of its manufacturer, Syngenta. Syngenta is a Swiss company, and interestingly, atrazine is banned in Europe. In the US, we’re allowed to have up to 3 parts per billion in our drinking water, and Syngenta initially commissioned Hayes to research possible deleterious effects of atrazine.
