I'm confused.  I thought the point of this thread was to discuss possible 
explanantions for the persistence of sexual reproduction in the face a 
presumed cost to the female.  If the point of this thread is to argue the 
merits of Eldredge's book or Dawkins' "ultra-Darwinist" viewpoint, then 
fine.  If Eldredge argues that sex makes no sense in the context of 
Dawkins' argument, then either (1) Eldrege is wrong - sex is compatible 
with Dawkins - or (2) Dawkins is wrong.  Either way, this has little to do 
with the origin and maintenance of sex - i.e., the actual study of 
evolution.  Neither Eldredge nor Dawkins - regardless of their collective 
contributions to evolutionary biology - should serve as a focus for 
discussions on the evolution of sex.

So what *is* the point to this thread?
