Wilkins is about to review a new paper on sociobiology by Wilson and Wilson, but he hasn’t quite done it yet. I’ll be looking forward to it, though.

Clive Thompson wants us to simply redefine the “theory of evolution” as the “law of evolution”. This is possibly one of the worst ideas I’ve heard yet for overcoming the problem of the colloquial definition of theory. It is not correct. The theory of evolution is a whole collection of ideas describing complex phenomena; it is not reducible to the kind of clear and simple mathematical description we associate with scientific laws. When somebody asks me what the ideal gas law is, I can say PV=nRT; when someone asks me what the law describing the gravitational attraction between two bodies is, I say Gm1m2/R2; when they say, “OK, smartie pants, what is the law of evolution?”, what am I supposed to do? Recite Hardy-Weinberg at them (which, by the way, is called a law already, but is not the sum of all of evolution by any means)?
It’s a bad idea that sets us up for more confusion and will play right into creationist hands. Why not go all the way and just call it the “Truth of Evolution”? It’s the same strategy — it’s all avoiding the issue by an attempt at redefinition, and mangling the idea in the process.
(Larry Moran sees it the same way I do. He must be a very smart man.)
(And Wilkins was way, way ahead of us both.)
Perhaps you haven’t noticed, but we’ve got a serial spammer in the comments. This twit, calling himself Peter Moore (also known as Ken DeMyer, or Kdbuffalo, as he was known on Wikipedia before being banned there), is repeating himself over and over again, asking the same stupid question, never satisfied with any answer anyone gives him. Forty nine insipid comments in three days is enough.
I will answer him one last time. Any further attempt to spam multiple comment threads with his demands (and this alone makes him an ass: an incompetent, unqualified hack like Moore is in no position to make demands) will result in his immediate banning.
Here’s an interesting thought and modeling experiment: how to evolve a watch, literally.
As an example, it’s nice, but there are also real biological examples of organisms evolving clocks — evolution of the period gene, for instance, which also shows evidence of being calibrated to day lengths by natural processes, or the somitic clock. Most organisms on the planet seem to have multiple clocks built right into them, and they’ve all evolved.

I was just turned on to this recent issue of the McGill Journal of Education which has the theme of teaching evolution. It’s a must-read for science educators, with articles by UM’s own Randy Moore, Robert Pennock, Branch of the NCSE, and Eugenie Scott, and it’s all good. I have to call particular attention the article by Massimo Pigliucci, “The evolution-creation wars: why teaching more science just is not enough”, mainly because, as I was reading it, I was finding it a little freaky, like he’s been reading my mind, or maybe I’ve been subconsciously catching Pigliucci’s psychic emanations. I think I just need to tell everyone to do exactly what this guy says.
So that’s what Carl Buell has been up to…Donald Prothero and Carl have been working on a new book, Evolution: What the Fossils Say and Why It Matters(amzn/b&n/abe/pwll), containing descriptions of important transitional fossils, and as you can tell from the title, directly countering some of the silly claims of the creationists. This is going to be one of those books everyone must have.
To whet your appetite, Carl sent along one of the many color plates that will be in the book—this is Sinodelphys, a 125 million year old marsupial.
You’re already drooling, aren’t you? You want this book. You must have this book. It’s less than $30 at Amazon; it’s not available just yet, but any moment now…so pre-order it already!
My latest column for Seed is now available online. It’s an abbreviated summary of how vertebrates make segments (so it’s illustrated with a fly…), with special emphasis on the global and clocklike mechanism we use.
I was sitting down this evening to write up this nifty new paper from the Carroll lab, when I noticed that Carl Zimmer beat me to it. Dang. There are all these other bloggers around here, and it’s hard to keep on top of all of them, all at once.
Go read it anyway. It’s good stuff, all about the importance of regulatory changes in evolution.
Early Cambrian shrimp! I just had to share this pretty little fellow, a newly described eucrustacean from the lower Cambrian, about 525 million years ago. It’s small — the larva here is about 1.8mm long, and the adults are thought to have been 3mm long — but it was probably numerous, and I like to imagine clouds of these small arthropods swarming in ancient seas.
