The answer to my question of the scientific explanation for how voids are filled is presumably the usual story of reproductive advantage as, in effect, the definition for how well a void's template is matched -- to use Dave's terminology. That's not quite circular in that it defines how well a void is filled as the extent to which whatever is filling the void succeeds in reproducing. The more successful, the better we say the void's "outline" is matched.
The problem (or rather inadequacy) I see with that definition is that it leaves open the question of whether one can find a more insightful definition for how well a void is filled. Reproductive success is fairly far removed from the notion of void filling. If one wants to use the terminology (or even analogy) of void filling, it would be nice to have a more direct way of saying what it means to fill a void successfully -- i.e., something more than just increased reproductive success. One might argue that there is no better description. But it that's one's position, let's be clear about it. My position is that we shouldn't give up so soon. That's the motivation for my question. *-- Russ Abbott* *_____________________________________________* *** Professor, Computer Science* * California State University, Los Angeles* * Google voice: 747-*999-5105 * blog: *http://russabbott.blogspot.com/ vita: http://sites.google.com/site/russabbott/ *_____________________________________________* On Wed, May 11, 2011 at 9:13 PM, Russ Abbott <russ.abb...@gmail.com> wrote: > Lots to respond to.
