I asked that you present a single reference that supports Gould's (and
your) straw-man characterization of sociobiologists. Let's get through
that issue, first, and then I'll be happy to post references by Daly &
Wilson and others that address jealousy specifically.
In the mean while, please present even one ultimate (evolutionary)
hypothesis for the emotions which explains how they came to be without
resorting to natural selection.

Helena Cronin has compiled quotes of them saying just that. Her book is
_The Ant and the Peacock_, and she patiently explains how the
adaptationist assumption that only natural selection creates
sophisticated traits (adaptations) is misunderstood by Gould et al. as
evidence that adaptationists generally see every single trait as not only
adaptive, but currently so, and optimally so.
>In the field of sociobiology, E.O. Wilson writes on page 22 of "Sociobiology"
It's natural that those ignorant of the field would think Ed Wilson is
the be-all, end-all of sociobiology (he wrote a book with that title,
after all). But he really isn't spokesman for the effort. Quote
Hamilton and Williams and Trivers, if you want to address the issues
close to sociobiologists' hearts.
Wilson may well, by the way, be guilty of pan-optimality thinking. He's
mistaken. On the other hand, is he *more* mistaken than those who see

Neurobiological studies have profoundly supported adaptationist, "modular
brain" models of the mind as a collection of task-specific (cognitively
speaking) information processing organs. I highly recommend "The Adapted
Mind," a 1992 edited volume put out by Oxford Univ. Press.

That's tremendously ironic, Paul. Love it! He purposefully (and
explicitly) adopted Gould/Lewontin's style to make a point. It is *not*
typical of how adaptationists argue their ideas.
Your reaction to the other side adopting the unfair rhetorical tactics of
Gould (whose writings you've never objected to here) reveals a very deep
bias on your part against neo-Darwinism. Time to do some soul-searching,
I look forward to seeing those non-selectionist hypotheses for the
origins of emotions, Paul. Impress us.
