We’ve got another chittering weasel of a creationist raving in the comments, a fellow going by the name YesYouNeedJesus. He’s also sending me email.

PZ, I first heard about you on Bob Enyart’s radio show about the fact that you turned down an offer to debate Bob. I must say that my first impression of you is that you are smarter than most evolutionists. Smarter because the evolutionists that debate Bob get absolutely destroyed every time. Every evolutionist that I spoke to who was at the debate between Bob Enyart and Reasons to Believe willfully admitted that their side (evolution) lost. Bob’s debate with Eugenie Scott was just flat-out epic and is still my all-time favorite science debate. Of course they all made the mistake of debating Bob and you did not. You are smart, I’ll give you that. I think they made the mistake of underestimating Bob because he’s just a radio talk show host. Personally I think that Walt Brown is the greatest scientist of our day, but after Walt Brown, Bob is one of the most brilliant scientific minds I’ve ever listened to. I believe that the evolutionist’s new tactic is to avoid debating creationists because the arguments are just becoming impossible to refute. While that’s quite the tactical strategy and may work for a short time, it is encouraging to see the creation movement grow like a wildfire. And I do believe it’s just a short amount of time before we see evolution become the next ‘spontaneous generation’ and become obsolete. Don’t forget that if you dared question spontaneous generation, you were labeled as anti-science. Good luck to you. -Will

You read that, and apart from the creationist crazy, you get the impression that this guy is just someone with no ties to Enyart (other than his deep and abiding passionate love for him) who listened to the radio show, found out about these evilutionists, and ran over here to see what was up.

This is not the case. His name is Will Duffy, something revealed in the first few minutes of the video below, and he’s Bob Enyart’s producer.

You know, this kind of thing really bugs me. Why do you have to lie and mislead and conceal on the little, trivial things? Why hide the fact that you have a vested interest in Enyart’s show, and are actually deeply involved in the program? I see that, and right away, I know I’m dealing with a shameless liar for Jesus.

And then, of course, there’s the raving insanity. Walt Brown and Bob Enyart are the greatest scientists of the day? Someone alert the NAS and the Nobel Foundation!

Here’s the video. It’s a year old, and it’s a surprise to me (which goes to show how impressed I am with this Enyart freak). I dismissed a request to debate this kook — I’d just come off a debate with his loony pal, Jerry Bergman — and so he issued a challenge that I hadn’t even noticed until now.

He’s asking me to explain the origin of the superior oblique muscle, one of the extra-ocular muscles, which has a tendon that travels through a pulley-like strap called a trochlea. This muscle abducts and depresses the eye; try to look at your nose, and that’s one of the muscles responsible for pulling the eyeball in that direction. Enyart thinks the muscle would have been useless without the trochlear pulley, which is silly: the muscle could have had a different attachment in the orbit, or in the absence of the trochlea could have swiveled the eye upwards, or most likely of all, the suite of extra-ocular muscles and that little loop of tendon all co-evolved. We are well-integrated wholes, you know, and we didn’t evolve one toe at a time — nature selected for functionality as a complete organism.

OK, but Enyart has challenged me to explain how this feature evolved. I have an answer. It’s easy.

I don’t know.

I don’t see any obvious obstacle to an arrangement of muscles evolving, but I don’t know the details of this particular set. And there’s actually a very good reason for that.

This is a case where you have to step back from the creationist and look at the big picture. Don’t get bogged down in the details. Take a look at the whole context of the question.

We don’t know exactly how this evolved because all living vertebrates, with the exception of the lamprey, have the same arrangement of extra-ocular muscles. This is a primitive and very highly conserved condition, with no extant intermediates. We’ve seen the arrangement of these muscles in 400 million year old placoderm fossils, and they’re the same; these muscles probably evolved 450 million or more years ago, and we have no record of any intermediate state. So I don’t know, and neither does anyone else.

But that’s where we have to look at the big picture: Bob Enyart, a raving loon and young earth creationist who thinks the whole planet is less than 10,000 years old, is asking me to recount the details of an event that occurred almost half a billion years ago. I should think it’s enough to shatter his position and show that he’s wrong to simply note that however it evolved, it happened in animals 75,000 times older than he claims the planet is. Has he even noticed this little problem with his question?

I don’t think “one of the most brilliant minds” has.

Further, another of Will Duffy’s rants here has made a strange demand. Mary Schweitzer and Jack Horner identified some peculiar soft tissue deep in a T. rex bone, which Schweitzer claims is preserved collagen or fragments of blood vessels. This has been disputed, and some claim it’s scraps of a bacterial biofilm. But the main thing is that an unusual and difficult to identify material was found in a Cretaceous bone.

Will Duffy wants it carbon-dated. The fossil has already been dated; it’s over 70 million years old. Carbon dating is only good up to a maximum age of about 50,000 years. He wants to hold a yardstick up against a mile-long object and ask how long it is. This makes no sense at all.

Bob Enyart called Jack Horner and offered him $20,000 to measure the C₁₄ in the T. rex specimen. You can tell Horner is both stunned and amused at the stupidity of the request.

The age of the specimen is not in question, and even if it were, carbon dating is so absurdly inappropriate and useless that only an ignorant clown would ask to do it: it doesn’t matter what number would come out of the measurement, it would be spurious, irrelevant, and uninterpretable…except that, because C₁₄ does have an upper bound of 50,000 years, whatever number reported would be less than that, which is exactly what the creationists are trusting would happen. They’d love to hold that yardstick up against the mile long object and triumphantly announce that it’s only 36 inches long.

“Brilliant mind,” hah. That’s not a brain, it’s a dingleberry with pretensions.
