I don't think that anyone in the EP camp would make that claim, at least
not directly. Genes build brains that operate bodies that exhibit complex
behavior. However, those brains *do* have obviously evolved psychological
mechanisms such as mother-infant bonding, pair bonding, those that are
turned on in capture-bonding, and attention-reward. *All* of these are of
the "flood the brain with chemicals" variety. While these floods will
reward behavior or even cause it (flight) they are hardly "complex
behavioural suites are under genetic control." Another universal
psychological trait is to diminish within the group fighting when the group
is attacked. It too might be of the chemical flood type, but that's uncertain.
About the most complicated behavior I know about that is directly linked to
a gene is "waltzing" in mice. http://pages.slc.edu/~krader/sunarticle.html
"A Japanese book, Chingan Sodategusa, detailed popular early breeds
-- the albino, dwarf and waltzing mouse (so named because the mouse
appeared to dance, a behavior, scientists later learned, that stemmed from
an inherited inner-ear defect)."

I think drug addiction, which sure can be a dysfunctional behaviour, is
being understood in terms of EP and brain reward circuits shaped by
evolution.

The extreme version of capture-bonding (Elizabeth Smart, Patty Hearst) is
rare enough to mystify people, but I think that understanding that people
*have* such a trait is important in treating battered wives, or controlling
hazing.

It has been ages since I read Thornhill. I don't remember him *promoting*
rape, just trying to understand the origin of a behavior that
*is* abhorrent and less successfully speculating about ways we might
compensate with a psychological trait that is way out of step with the
modern world. I probably should reread Thornhill and do a post on this
subject.
In a species that depends on pair bonding and a lot of paternal investment,
rape as a reproductive strategy would only be possible if it were a rare
strategy. That means it would be done by either a very few individuals or
as an uncommon behavior for a larger number. You might want to read
Baker's Sperm Wars. Very disturbing book, but hard to fault at the
science/EP level. (Getting the name spelling right turned up
this: http://www.ulm.edu/~palmer/SpermWars.htm)

Either you or the media are completely missing the point.
