…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.

Why, Michael Lynch wants to know, don’t we look like bacteria?
Evolutionary biologists generally agree that humans and other living species are descended from bacterialike ancestors. But before about two billion years ago, human ancestors branched off.
This new group, called eukaryotes, also gave rise to other animals, plants, fungi and protozoans. The differences between eukaryotes and other organisms, known as prokaryotes, are numerous and profound. Dr. Lynch, a biologist at Indiana University, is one of many scientists pondering how those differences evolved.

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.
I’ll be in Ann Arbor for a talk on January 14 at the natural history museum in conjunction with the opening of the “Explore Evolution” exhibit there. I’ll talk about reporting on new research in evolutionary biology.
