[Taxacom] Darwin's Doubt

Hi Fred,


 Many of the animal phyla probably existed long before the Cambrian, but they were then tiny and had no hard

 parts to indicate their presence in the fossil record.  I've never liked the idea of a Cambrian "explosion"

 of taxa, and therefore believe it was more likely a sort of "explosion of hard parts" in various already-established

 taxa in different phyla due to changes in ocean chemistry (as I expressed in a 2001 posting that I made

 on the Dinosaur Mailing List:

 http://dinosaurmailinglist.cmnh.org/2001Mar/msg00191.html .  Some years later, I recall someone publishing a

 similar hypothesis, and called it something like the "Cambrian slow fuse", rather than an explosion.  Since it

 wasn't sudden, there was "sufficient time" for the required mutations.

* thanks for these general thoughts on Intelligent Design - but I was
wondering about commentary on this particular book, and its assertions
about the Cambrian diversification of Animal phyla, and more
particularly on the general ID assertion that there hasn't been
sufficient time for mutations to originate and be organized into
adaptations by natural selection. This seems absurd to me, but ID sorts
constantly make it. Rather than seeing the punctuations of punk-eek as
the Red Queen unleashed by a lack of stabilizing selection, they affirm
that this is the finger of God poking lineages along in a divine
direction, and that anything that can be observed to happen isn't
"macro" enough to count as real evolutionary change. I wonder if there's
a published straight-on refutation of this?

If there isn't, I'll chew my way through the book, and see where it
goes. So far, I think it's charming the way the author blames Darwin for
not being up on all the nuances of the evolution of protein folding...
