It’s 42 minutes after 7

Approximately 563 minutes ago, I noticed this peculiar analysis of language use on Pharyngula that suggested that we use the phrase “N minutes”, where N is 5 or 10, with a slightly greater frequency than the web population as a whole. This made me self-conscious for a whole 18 minutes, so I thought I’d better sleep on it for about 480 minutes before taking 4 minutes to make a short post about it. Go on and read the Language Log — it’s short and will probably take you only 2 minutes to skim through it.

Now I’m thinking, because I’m an evil and devious sort, that since this is already a low frequency event where we use that phrase, we can easily muck with people’s heads while demonstrating an observer effect. From now on, everyone try to remember that whenever you reference a short estimated interval of time, and you are about to use one of the common multiples of 5, add one to it. We don’t have to do it every time, nor does everyone have to participate, but by adding a little verbal tic on top of a tic we can skew this analysis.

The experiment began 11 minutes ago. Keep it up.

What’s happening down in New Zealand?

Watch and find out next week, as the Museum of New Zealand Te Papa Tongarewa prepares to move the Colossal Squid live, on webcam. It’s going from its formalin soak to a new display tank. Along the way they’ll sew up a rip in the mantle, remove some eggs and check how it has preserved.

The live webcast starts at 9am NZ time on Wednesday 6 August, USA time Tuesday, 5 August, 2pm PDT, 5pm EDT and UK time Tuesday, 5 August, 10pm.

This could be a dreary mistake

I’ve agreed to another talk radio debate — this time it’s not a Christian radio station, so there’s hope of some ethical behavior on their part — on WDAY, AM 970 next Tuesday, 5 August, at 10am. We’re supposed to debate intelligent design, and my opponent is…

My opponent is…

Really, I’m embarrassed to say it…

My opponent is…

Ray Comfort.

O Lord, could you please stop making my enemies so ridiculous? It’s getting a little bit excessive.

Basics: Sonic Hedgehog

Every time I mention this developmentally significant molecule, Sonic hedgehog, I get a volley of questions about whether it is really called that, what it does, and why it keeps cropping up in articles about everything from snake fangs to mouse penises to whale fins to worm brains. The time seems appropriate to give a brief introduction to the hedgehog family of signaling molecules.

First, a brief overview of what Sonic hedgehog, or shh, is, which will also give you an idea about why it keeps coming up in these development papers. We often compare the genome to a toolbox — a collection of tools that play various roles in the construction of an organism. If I had to say what tool Sonic hedgehog is most like (keeping in mind that metaphors should not be overstretched), it would be like a tape measure. It’s going to have multiple uses: as a straightedge, as a paperweight to hold down your blueprints, as something to fence with your coworkers on a break, and even to measure distances. It will be pulled out at multiple times during a construction job, and it’s generically useful — you don’t need one tape measure to measure windows, another to measure doors, and yet another to measure countertops. Sonic hedgehog is just like that, getting whipped out multiple times for multiple uses during development, often being used where structures need to be patterned.

Let’s dig into some of the details. I’m using the 2006 review by Ingham and Placzek for most of this summary, so if you really want to get deeper into the literature, I recommend that paper as a starting point.

A horrible story

You’ve probably already heard this one, since it is all over the news: a preacher, Anthony Hopkins, murdered his wife after she caught him sexually abusing their children and stuffed her in a freezer — with the daughter’s assistance. This happened four years ago and the children’s mother has been kept in the freezer in this house ever since. The pastor of Hopkins church reports that “the children were so respectful, just so easygoing”, and that they “loved their dad. They were very close to him.” Right. Rape, murder, and incest are just ordinary events in the Abrahamic family tree.

What I find disturbing about the whole story is this. Anthony Hopkins spent all this time since as an itinerant preacher, traveling about and preaching the ‘Holy Word of Jesus Christ’. His daughter moved out of his house, finally, reported what he’d done to the police, the police went into his house and opened the freezer, and then they went off to the church where he was preaching that day. What did they do then?

Police allowed Hopkins to finish his sermon before arresting him.

Wait, what? Was this an example of Christians showing respect, that they allowed a child-raping murderer continue mouthing words of love and redemption in their church, words that clearly meant nothing to this monstrous psychopath? If only he’d crumbled a cracker, perhaps then they would have been less tolerant.

An inspirational poster

I must confess to a cruel game with this post. I saw this poster and thought, “What? But most of these people weren’t atheists!” Surely someone could do a far better job with this idea than that, and everyone would see the problem here (at least John Wilkins did, as did many of the commenters). You were supposed to be inspired to make a better version. At least one person was, but they took it in a completely different direction than I expected.

Anyone care to try and do something better, with a positive message?

Only a Theory

I published a review in Nature this week, of Ken Miller’s Only a Theory(amzn/b&n/abe/pwll), and boy, was that a tough one. The catch was that I want the book to do well, and I definitely think it has a place as an appeal to the religious majority to support good science (you know, all those people who see my demonic visage leering out at them from the top left corner of this page and want to call for an exorcist), but it also irritated me greatly on several important points.

I think it’s a much better book than his previous, Finding Darwin’s God(amzn/b&n/abe/pwll). That book had one point where it simply drove off the cliff with a bunch of handwaving about god dwelling in quantum indeterminacy, which made it virtually unreadable beyond that point. There is no cliff in this one; instead, it’s threaded with some annoying biases throughout.

The big one for me was a lot of naive American exceptionalism, and that’s the issue for which I took him to task in the Nature review. Why does the US have such an aberrant problem with creationism, while Europe does not? I would have answered with something about a tradition of religiosity and anti-intellectualism, and maybe something about a rough-and-ready credulity that allowed for the rapid proliferation of widely variant sects; the recent renascence of creationism under the guise of ID owes something to raging relativism, too. In Miller’s eyes, creationism has absolutely nothing to do with religion at all — it’s all about the American virtues of rebelliousness and disrespect, to which we also owe our eminence in science.

This is news to me, especially lately since Miller’s co-religionists have been madly flinging bricks at me for daring to disrespect their peculiar superstitions. I also don’t think the sheep flocking to the mega-churches are flaunting their rebelliousness…it’s more an expression of conformity. There isn’t one true revolutionary among the creationist hordes, only a mob trying to defend hallowed superstitions from the encroaching modernity. Any explanation for the popularity of creationism that discounts the impact of religion for the worse is like trying to explain the motion of a car while completely ignoring the engine compartment.

The other annoyance of his book creeps in gradually. He’s clearly a fan of Simon Conway Morris’s view that life roughly of our sort was inevitable, that while evolution would lead to variations in the details, a human-like mind was a consequence that was programmed into the starting conditions of the universe. If we restarted the Earth at a point 4 billion years ago, the planet would eventually cough up a pile of social animals that would start going to church and praising their heavenly creator — maybe they wouldn’t be mammals, but our molluscan or reptilian or echinoderm replacements on Alternate Earth would still be occupying a similar niche to ours, and would still be fulfilling the rough outlines of the vision set in motion by a loving god.

This is, of course, untestable wishful thinking, and not at all supported by the science, which shows a genuine role for chance. Real chance. Not the chance of Miller, which is that of a god who throws dice most of the time, but when it is really, really important, he fudges the results a little bit to make sure he wins.

Still, you should read the book. Ignore the apologetics, and don’t trust anything he says about the origins of creationism in the US, but do read it for the excellent rebuttals to common creationist claims. This is a book I’d hand to any creationist students who try to argue against evolution on religious grounds, but I think it would only take them partway to a realistic view of how life came to be.
