Mimio: the problem is that NS is a conservative force. It ensures extinction ultimately ala deleterious mutations. It's not creative and cannot produce novel genetic information. Dimorphic sexuality certainly does yield more diversity per generation, but blind, conservative mechanisms do not have the forethought to realize this and would not have relevant data in the asexual creature to apply selection pressures to.
None of this even broaches the subject of biochemical steps in going from an asexual creature to a dimorphic one. My head spins to even dream on that one. Again, biological novelty cannot be purchased without intelligence to input the information either in the front end or at intervals of it's choosing.
It's very easy to say "can go for sexual over a-sexual". It's a much bigger challenge to demonstrate how non-telic Darwinian mechanisms can make it happen.
