Ridicule works!

The threat of an eruption of creationism in Polk County, Florida, is dying down. The school board hasn’t changed, it still has a number of confident creationists on it, but they’re all going to keep their religious beliefs at home and in church, and in fact, they have a “great eagerness simply to return to the day-to-day work of running a school district with 90,000 students.” It’s great news all around.

What got them to confine their interest to doing their job? As the article explains, a lot of factors contributed. The county wants tech sector jobs and expansion of a University of South Florida campus, and they got biting comments from the people behind those economically important initiatives. They had the Dover trial waved in their faces, and saw the threat of expensive litigation and even more expensive defeat. And they got ridiculed on a local and national level—bloggers and magazines mocked them, they got mail from proponents of the flying spaghetti monster, their quaintly ridiculous religious views got publicized on the front page of local newspapers.

Creationists hold some very stupid ideas, but most of them aren’t stupid people. They know deep-down that their religious beliefs are indefensible on a plane that demands evidence and results, and while they aren’t going to give up those beliefs, they’d rather be spared the embarrassment of having to lay them out and explain them in scientific terms. A good loud campaign of public ridicule can be just the thing to convince them to put their heads down and buckle into the secular work they’re supposed to be doing.

Creepy Texas dentist slathers on the smarm

Godless heathen that I am, even I can read the subtext in Don McLeroy’s recent letter to the Dallas Morning News. First he reassures us that he is very, very, very Christian, and then he promises to purge the dogma from Texas education. We know what that means in the up-means-down world of Christianist fanaticism: the dogma is the science and his empirical evidence is the revealed word of his Lord, Jesus Christ.

I’ve heard a few words about the situation looking up in Florida, but Texas is a dismal scary place for evolution education — I’m going to have to put a few more quatloos on Texas in the creationist courtroom catastrophe pool.

Steve Fuller gets reamed

Steve Fuller, the smug sociologist who testified for the creationists in the Dover trial, has a new book out. Who cares about the book, though? You want to read Norman Levitt’s review, “The Painful Elaboration of the Fatuous”. Wow. Fuller gets deconstructed.

Here’s a small taste.

A similar farce plays out when Fuller tries to address the larger question of the supposedly contentious nature of evolutionary theory within the scientific community itself. In the World According to Fuller, evolutionary theory never really got past the stage of being a “well evidenced ideology” rather than a “properly testable science” (p. 123). What he is saying, in effect, is that the claims from all branches of biology and related science that they have contributed to a vast stream of convergent evidence verifying the essential precepts of evolution are in great measure delusional. He seems to think that biology, as a constellation of disciplines, is some kind of socially-constructed freemasonry in which assent to basic Darwinian principles constitutes a ritual formula necessary to make one part of the brotherhood rather than a cognitively-justified inference from hard evidence. More, he seems to think that evolutionary thought is mere ideological window-dressing, contributing nothing to the “hard science” behind molecular biology and the like.

None of this is backed up by serious analysis of the working methods and logical structure of biology itself. Fuller complacently views the ascendancy of evolutionary thought as a “rhetorical” rather than a “scientific” development. His principal evidence? The paucity of Nobel Prizes awarded for work on evolution! Of course, he never pauses to consider that under the idiosyncratic organization of the Nobel awards, there is no prize for biology as such. Biologists are smuggled in under the “Medicine and Physiology” category, which is just expansive enough to accommodate ethologists like Lorenz or Tinbergen, but not hard-core evolutionary theorists. In all of these pronouncements, Fuller is hard-pressed to hide his scorn for actual scientists who, it is obvious to him, know much less about what they think and how and why than a social theorist like himself who is enormously content to cite his own work endlessly.

…and that’s one of the kinder bits. Enjoy it all!

Evolution of vertebrate eyes

Blogging on Peer-Reviewed Research

A while back, I summarized a review of the evolution of eyes across the whole of the metazoa — it doesn’t matter whether we’re looking at flies or jellyfish or salmon or shrimp, when you get right down to the biochemistry and cell biology of photoreception, the common ancestry of the visual system is apparent. Vision evolved in the pre-Cambrian, and we have all inherited the same basic machinery — since then, we’ve mainly been elaborating, refining, and randomly varying the structures that add functionality to the eye.

Now there’s a new and wonderfully comprehensive review of the evolution of eyes in one specific lineage, the vertebrates. The message is that, once again, all the heavy lifting, the evolution of a muscled eyeball with a lens and retinal circuitry, was accomplished early, between 550 and 500 million years ago. Most of what biology has been doing since is tweaking — significant tweaking, I’m sure, but the differences between a lamprey eye and our eyes are in the details, not the overall structure.

Octopus abuse!

Initially, I was horrified at what was being done to the hapless cephalopod, but then I saw the stereotype on the right, and realized the real crime was against the kids reading this tripe. (No, my name isn’t Fredric Wertham.)
