I'm interested in finding out how Meyer thinks ID works (when I get back to reading Darwin's Doubt). Also in how Behe thinks it works, or has worked, in the book Darwin's Black Box which Khandro's reading.
As Meyer is claiming ID as a scientific theory, not a religious one, then he will need to at least hypothesize how ID worked to produce the Cambrian explosion. The creationist will say the God designed the trilobite with its complex eye and created it from nothing. But Meyer, as a proponent of science, has disallowed himself this recourse to magic. So how exactly did the intelligent designer do it? Did he construct it in a laboratory and transport it here? Did he take an earlier form (maybe one without a complex eye) and genetically modify it to produce a them. As the premise of ID is that unguided natural mechanisms cannot account for big and rapid changes, then we have to presume that the designer has to intervene quite often, certainly at times of rapid change such as the Cambrian. This begins to look like Gould's punctuated evolution, but with fewer semi-colons and more exclamation marks. Or it is possible the designer is at some level actively engaged in genetic modification all the time, sustaining evolutionary diversification in a similar way it was once thought that angels sustained the motion of the planets? Having come up with a plausible hypothesis, he will then have to suggest ways in which this might be tested (and, indeed, falsified). So something a cut above postulates such as "moved by angels" which are immune to experimentationtulate. Behe will have to do the same thing after he has patiently explained how the human immune system and the bacterial flagellum could NOT have evolved without a designer. I suspect neither author will be too forthcoming in expounding their ideas about this fundamentals of science.
ID raises other, philosophical questions, too. Not the least of these is why, if there is a supervising (or, at least, interested) intelligence, so many extinctions have occurred with all the apparent waste that these imply.
