I've gotten this msg twice, probably due to a glitch here at UNM.
Anyway, I thought it over and decided that you're probably correct; I was
too quick to jump to specific examples that were new to me rather than
sticking to argument from principle.

Ironically, I picked jealousy and sugar craving as crude, "common-sense"
examples to illustrate a point, and didn't intend to end up defending
adaptationist perspectives of these phenomena!

But that's what I ended up doing, nevertheless. Live and learn.

I should have said, "if we accept that X and Y are evolved traits," they
still need not be currently adaptive (my original point, I believe).
