BPSDBRichard Dawkins and PZ Myers had a lengthy, informal chat during the 2008 American Atheists conference in Minneapolis, and a recording of their conversation is now available on DVD and in the video tubes. They discuss the fight against pseudoscience as well as several interesting topics in good science.

I did my best to summarize the kin-vs.-group business in this book review. Among the “glimmerings” which suggest there’s a better way to think about some evolutionary processes (name for that better way still to be defined) are, I think, the epidemiological simulations in which fitness of a genotype is clearly a function of ecology and thus strongly time-dependent, and consequently existing analysis techniques are likely to fail. Assuming this kind of thing happens in the real world, it might be better to speak of “extending the evolutionary stable strategies concept” or “temporally extended phenotypes” than to have yet another largely semantic argument over “group selection.”

Also of note:

When Dawkins spoke at the first artificial life conference in Los Alamos, New Mexico, in 1987, he delivered a paper on “The Evolution of Evolvability.” This essay argues that evolvability is a trait that can be (and has been) selected for in evolution. The ability to be genetically responsive to the environment through such a mechanism as, say, sex, has an enormous impact on one’s evolutionary fitness. Dawkins’s paper has become essential reading in the artificial life community.

Anyway, on with the show.

P-Zed wrote an introduction to allometry a little over a year ago.

Let’s see, P-Zed reviewed Dowd’s book here, and back in 2000, Russell Blackford wrote up a take on NOMA which is pretty much what Dawkins and Myers are saying here.

Here’s the Americans United website.

William Dembski was the one who said, “Intelligent design is just the Logos theology of John’s Gospel restated in the idiom of information theory.” He has also declared, “So, too, Christology tells us that the conceptual soundness of a scientific theory cannot be maintained apart from Christ.” (That’s from his 1999 book Intelligent Design: The Bridge between Science and Theology.) Michael Behe admitted that ID is religious both in Time magazine and on The Colbert Report.

Avalos has some interesting points on the “two-face” issue.

I’m not sure I care to hear Dawkins and Myers casting aspersions on quantum feminism.

Ooh, wow — this is the prelude to the Theatre Incident! History, extremely funny history, is about to be made. This is “Sabot Day,” the day commemorated forevermore with a ceremony

where we all dress up as Dawkins to go see this movie at the local art-house theatre, and leave a token, sacrificial friend dressed up as a squid outside where they play with their Mac.

Good times.

The propaganda flick Expelled has turned out to be, well, rather a flop. Oh, and it was later found that Expelled did not use the XVIVO footage itself but rather an astonishingly plagiaristic rip-off.

The legal dispute over this seems to have petered out, but with Expelled being a box-office disaster anyway, maybe we just shouldn’t care. OK, on with the programme.

On the subject of changing one’s mind after being questioned, see here.

Mmmm, parasites. I bet Carl Zimmer likes this part.

Let’s see, P-Zed has a treatment of choanoflagellates and several segments on, er, segmentation, in Drosophila as well as in vertebrates.

Last clip:

It’s very interesting that we might have to talk about “the selfish regulatory gene” or “the selfish set-of-spliced-together-exons” or perhaps even “the selfish epigene.”

  1. Isn’t it a bit unkind of you to put the BPSDB logo on this post? People might think you’re a Catholic.

  2. If people are incapable of reading to the second sentence of my post, I’m not sure I should care about their opinion.

    By playing fair, I take it you mean sitting down and shutting up as the enviromentalists threaten and intimidate their way to one world government, make breathing a criminal offense, ruthlessly impliment their population control measures through regulation restrictions and artificially increased food prices, thus disposing of the excess population in the poorer regions of the planet? Wow thats just insane. Was posted at cocktail party physics, klimate kerfuffle. Blake I am at a lose for words….

  3. Um, I didn’t say that, and I’ll agree with you that it’s rather breathtaking. Blame this “Papertiger” person (who clearly has what specialists refer to as issues). On Jennifer’s site, the attribution for a comment appears below the comment itself (look at the end of the thread).

  4. I found the discussion of higher units of selection to be the most interesting part. As is pointed out in the video I think there’s a big problem with the semantics of the debate. When I think “group selection” I think E.O. Wilson and altruism. When I think “species selection” Stephen Jay Gould comes to mind. I hadn’t heard “clade selection” before but it’s yet another term with a different meaning. All of this has to do with higher levels of selection but what levels and what sort of modes of selection?

    I think studies of extinction (particularly mass extinctions) and invasive species could shed some light on this problem but at the moment it seems that there is such a varied terminology that we don’t know whether we’re coming or going half the time. (Even the discussion in the video fumbles towards defining some terms a bit.) Anyway, I think the question of higher levels of selection and evolvability are closely tied and provide some good questions for interdisciplinary work.

    Since Mr. Stacey purports to be a physicist, perhaps he should also post Google Videos to interviews Prof. Dawkins held with Lawrence Krauss and Steven Weinberg which are also available.

  5. Good point. The Lawrence Krauss interview is here and the Steven Weinberg one is here, but I haven’t had time to watch them.
