Wilkins explains it all

Wilkins is keeping us busy lately: he also has a a whole series on why creationists are creationists. The short answer to the problem he gives is to teach them the process of science, not the rote solutions, and to catch them early—I agree, college is too late. I think he missed one other corrective though. He has a diagram illustrating the forces on a growing mind that drive people towards science, or towards pro-tradition, strongly anti-science attitudes. I can’t help but notice that all the “folk-based heuristics” are driving attitudes towards the anti-science position.

There must be some folk-based heuristics that promote good science. Shouldn’t one of our strategies be to root out the anti-science forces at the earliest ages, replacing them with those science based heuristics or even folk heuristics that promote science? When there’s forces of ignorance dragging our children down, maybe we should also think about opposing the bad as well as promoting the good.

Man in funny hat dislikes, doesn’t understand evolution: News at 11!

The Pope speaks, John Wilkins replies. Wilkins is sufficient, but I just had to comment on one silly thing the pope said about the consequences of evolution.

Man, “would then be nothing more than a chance result of evolution and thus, in the end, equally meaningless,” said the Pope.

This is terrible news. Forget evolution; I am the chance result of one out of trillions of my father’s sperm meeting one out of hundreds of thousands of my mother’s ova. And, oh no, the allelic content of each of those gametes was the result of chance molecular events in meiosis. And each of those gametes contained a handful of random mutations. I can see in my brothers and sisters that chance could have resulted in rather different outcomes.

Whoa … my exalted manliness was also the result of a roughly 50:50 chance—it’s like one of the primary qualifications for Ratzinger to have become pope was little more than a coin flip.

So chance makes everything meaningless? I guess my life must be nothing, then, and the papacy too is just random noise. I guess in his recent get-together with his students on evolution, his reported willingness to listen was all a sham.

House jumps the shark

True confession: I try to watch the medical drama House when I can. It’s lead character is an acerbic and brilliant atheist M.D. (played by Hugh Laurie, a comedic actor—which was a smart casting decision), and the humor is snarky and dark. That’s just the kind of thing I enjoy. It’s been going downhill, I think, because the episodes have gotten far too predictable—there’s always a weird illness which is handled via increasingly wild semi-random diagnoses that always, and I definitely mean always, ends with the complete cure of the patient. The infallibility is wearing a little thin.

Last season’s finale almost made me give up. They turned the gross-out factor up to 11 (exploding testicles and eyeballs popping out), and resolved everything with the lamest, laziest television cliche: it was just a dream. I hoped it was just an aberration.

Last night’s episode, though, blew it. I have lost faith in House. <spoilers below>

The perfect date for the grand opening would be April First

Pam Spaulding reports that Ken Ham’s clown palace of a ‘museum’ will be opening in April. I am so tempted to make a road trip this summer to see it and mock it…but no, I don’t really want to put one penny in his coffers. I did think this was funny, though:

According to Ham, the museum is already receiving worldwide attention. “The international press are getting very, very interested in this,” he says, “and it’s going to be not just a national event here in America. It’s going to be an international event when it opens in April 2007.”

I’m sure it is getting lots of international attention. It’s a colossal joke and an embarrassment to this country.

Developmental Biology 4181: Week 2

This week, my students are thinking about SIDS,
aging,
Christiane Nusslein-Volhard,
oncogenes,
hunger,
individuality,
worm movies,
obesity,
sunscreen, and whether to
divide or die. A fairly typical set of undergraduate concerns, right?

They’ve all also been reading chapters 3 and 4 of Carroll’s Endless Forms Most Beautiful, and their summaries are here: α,
β,
γ,
δ,
ε, and
ζ.

If you missed it, here’s Last week’s digest and a brief explanation of what it’s all about.

Patterning the nervous system with Bmp

I’m a little surprised at the convergence of interest in this news report of a conserved mechanism of organizing the nervous system—I’ve gotten a half-dozen requests to explain what it all means. Is there a rising consciousness about evo-devo issues? What’s caused the sudden focus on this one paper?

It doesn’t really matter, I suppose. It’s an interesting observation about how both arthropods and vertebrates seem to partition regions along the dorso-ventral axis of the nervous system using exactly the same set of molecules, a remarkable degree of similarity that supports the idea of a common origin. Gradients of a molecule called Bmp may be the primitive mechanism for establishing dorso-ventral polarity in animals.

This is just not right

Stop it! Some misguided people are killing stingrays in apparent retribution for the death of Steve Irwin.

A fisheries department official says up to ten of the normally docile fish have been found dead and mutilated on Australia’s eastern coast since Steve Irwin was killed by one last week. At least two had their tails lopped off.

As the article goes on to say, this is the antithesis of what a conservationist like Irwin would have wanted.
