Rick Perry’s on board! And no postmodern vagueness for him. He’s here to tell us that intelligent design is a “valid scientific theory.” That’s right, governor. Just check out all the work on intelligent design going on in the biology department at your state’s fine university. Um…wait…it’s there somewhere. Just let me figure out how to work this search function…

As the proud owner of a fine cat, Tino, I’m happy to join the ritual of cat-blogging. I was inspired after reading a new study that sorts out Tino’s kinship with other cats. Now I know that a cheetah is more closely related to Tino than it is to a leopard (right and left, respectively).
The evolution of cats has been a tough nut to crack. While it’s no great mental feat to tell the difference between Tino and a tiger, it’s not so easy to figure out exactly which species are most closely related to domesticated cats and which are more distant relatives.
…to this gem I just received about my post on the Dover creationism case:
Carl,
It doesn’t bother you that the judge went beyond any human capacity to attack the board members, not for their actions, not for their efforts to remove science fiction from the science classroom (that would be a realistic description of Darwinian evolution as it is fictional and not factual), but rather because he stated they were trying to introduce religion into the classroom.
Tomorrow (Wednesday) at 4 pm EST I’ll be a guest on Science and Society, an online radio show. You can listen live or visit the site later for a podcast. I’ll do my best to be interesting on all things evolutionary, but fortunately I’m sandwiched between two scientists who should be definitely worth a listen: Steven Salzberg, who has sequenced the genomes of humans and flu viruses and just about everything in between, and Zach Hall, the president of the California Institute for Regenerative Medicine, which was set up to make California the world’s envy in stem cell research.
I have an article in tomorrow’s New York Times on a provocative theory about our origins. Humans, other animals, plants, fungi, and protozoans are all eukaryotes. We all share a distinctive genome compared to other organisms (prokaryotes, which include bacteria and archaea). Our genes are more versatile: they can be switched on an off in more complex patterns than in prokaryotes, and one gene can make many different proteins, depending on which parts of the gene our cells look at. Some scientists would like to say that this distinctiveness must be the product of natural selection.
