Performance Feedback Revision - a peer-reviewed hip-hop definition of Evolution!

Last year, we enjoyed Baba Brinkman's performance of The Rap Guide to Evolution on our campus when he was in Fresno for the Rogue Festival. His show has gone on to a larger world stage since, as you can see in the above video, from the Hammersmith Apollo in the UK. He was there as a part of Nerdstock: Nine Lessons and Carols for Godless People, which was recently broadcast on television by the BBC! You can watch the whole show on YouTube (if you're outside the UK and therefore not able to use BBC's iPlayer). I thought I should share Performance, Feedback, Revision here for my students since I am going over the basic conceptual framework of evolution in several classes these days - and Brinkman provides a fun restatement of some of the concepts, in rap (and peer-reviewd rap, no less!)! If you haven't done so yet, you really ought to go listen to the whole rap album, available via his website.

Now that's one fairly odd parent...

via telegraph.co.uk

Three piglets rests next to their adoptive mother, Sai Mai, an eight-year-old tiger, at the Sriracha Tiger Zoo in Thailand's Chonburi Province

What an incongrously touching image! And I wonder whoever thought of making this happen! What became of the piglet's biological mother? More importantly (in the larger rarity scale of things), what became of the tigress' cubs? She's surely had some recently if she's able to nurse...

Seminar today: Step-by-step evolution of the vertebrate blood coagulation system

Friday, January 29, 2010

3:00-4:00 PM in Science II, Room 109


Professor,

Dept. of Chemistry & Biochemistry and Molecular Biology

University of California, San Diego

La Jolla, CA

The availability of whole genome sequences for a variety of vertebrates is making it possible to reconstruct the step-by-step evolution of complex phenomena like blood coagulation, an event that in mammals involves the interplay of more than two dozen genetically encoded factors. Gene inventories for different organisms are revealing when during vertebrate evolution certain factors first made their appearance or, on occasion, disappeared from some lineages. The whole genome sequence databases of two protochordates and seven non-mammalian vertebrates were examined in search of some 20 genes known to be associated with blood clotting in mammals. No genuine orthologs were found in the protochordate genomes (sea squirt and amphioxus). As for vertebrates, although the jawless fish have genes for generating the thrombin-catalyzed conversion of fibrinogen to fibrin, they lack several clotting factors, including two thought to be essential for the activation of thrombin in mammals. Fish in general lack genes for the “contact factor” proteases, the predecessor forms of which make their first appearance in tetrapods. The full complement of factors known to be operating in humans doesn’t occur until pouched marsupials (opossum), at least one key factor still being absent in egg-laying mammals like the platypus.

Genie Scott on Evolution Versus Creationism

This is the second lecture of the course on Darwin's Legacy offered at Stanford in 2008. I posted the first lecture earlier today.

Darwin's Legacy: introduction to a course from Stanford University

On NCSE's Facebook page this morning I discovered a link to this wonderful series of lectures on Darwin's Legacy put together as a continuing education course by Stanford University in fall 2008. I will post the whole series here, since it has recently become available online. Or you can get a jump start and go to the source: watch the whole thing in YouTube videos like the one above on Academic Earth or download it to your favorite portable device by downloading it from iTunes U.

While we don't have Stanford's resources or reach, as you may know, we are nevertheless also hosting our own modest Evolutionary Biology Lecture Series under the umbrella of the Consortium for Evolutionary Studies at California State University, Fresno this year. And as some of you may remember, we had NCSE's Dr. Eugenie Scott speaking on campus last month; she's also featured as the second talk in the Stanford course. This friday we'll learn about the evolution of the vertebrate blood coagulation system from Dr. Russell Doolittle of UC San Diego. Join us if you can, or come back here for videos/podcasts - I will try to record and post as many as I can.

NOVA | Darwin's Darkest Hour

While the big cinema treatment of Darwin's great pause in publishing "On the Origin of Species" may never make it down to theatres in our neck of the woods, out here in California's Central Valley (not a big market for stories about Darwin, it seems!), the above version on PBS' Nova was actually quite compelling. Having read some mixed reviews of Creation (although most reviews have been positive), I wonder if this televisual treatment may actually be superior in capturing the remarkable intellectual ferment behind Darwin's work. Rather than the movie's dramatic emphasis (from what I've read) on the emotional drama of Darwin's life after the death of little Annie, this Nova biopic choses to focus more on the intellectual turmoil (without downplaying the emotional turmoil at all), and even has Charles and Emma going back and forth in a very compelling way as he develops his arguments. If you're fortunate to be living in a place where Creation was released in theatres (or have managed to score a copy to view somehow), I'd love to know what you think: how does this compare?

Brain Matters | The Human Spark | PBS Video

The final, and perhaps the most fascinating, part of the series anchored by Alan Alda. Go to the show's website for a lot more information and supporting material.
