Is there an entomologist in the house?

I got a request to help identify this bizarre creature. I’m guessing it’s a slug caterpillar, from the family Limacodidae, although I couldn’t possibly narrow it down further, and could be completely wrong. Whoever was filming it can be heard telling someone not to touch it—which is a good idea. These things shed fine hairs that can cause a painful allergic rash.

It’s kind of cute, anyway.

I think the collective wisdom of the internets has convinced me that it is a puss caterpillar, Megalopyge opercularis.

Francis Collins, doofus for the Lord

I just watched the Francis Collins/Charlie Rose interview (it starts at about 35 minutes on that clip), and although I struggled manfully to appreciate the fellow’s accomplishments and status in science, I failed. All I could see is that he was illogical, irrational, and downright goofy—all the symptoms of a severe affliction with a bad case of religion. That video ought to be a warning to scientists: even a prestigious scientist can suffer Christian mind-rot.

Just another Christian ranter on the fringe

He only has a few radio and television programs, his own university, tens of millions of dollars to throw at his political causes, and a few million voters in his pocket, so Jerry Falwell* is just a marginal nut, right? We can just ignore him when he says things like this:

It is apparent, in light of the rebirth of the State of Israel, that the present day events in the Holy Land may very well serve as a prelude or forerunner to the future Battle of Armageddon and the glorious return of Jesus Christ.

Those rapture freaks who are cheering on the bloodshed in the Middle East certainly don’t have any real clout…at least, not as much as us influential atheists, I’m sure.

A simple story gets complicated

People, scientists included, are always looking for simple, comprehensible explanations for complex phenomena. It’s so satisfying to be able to easily explain something in a sound bite, and sound bites are so much more easily accepted by an audience than some elaborate, difficult collection of details. For example, we often hear homosexual behavior reduced to being a “choice,” the product of a “gay gene,” a “sin,” or something similarly absolute and irreducible…suggesting that it is part of a diverse spectrum of sexual behaviors with multiple causes and that different individuals are different in their behaviors is almost certainly the more accurate description, but that doesn’t satisfy our need for straight, simple, linear causal mechanisms. This is true of most animal behavior, I think—you just can’t crunch it down to one single agent that drives much of anything.

I thought there was one excellent counter-example, though, one that suggested at least some complex behaviors might be reducible to a discrete source: the mating behavior of Microtus voles. It was such a simple, clean story; new results suggest that it was too clean, and that there’s much more to the behavior than was thought.
