Promiscuity is the norm for some cultures. The idea of "this is my
woman, so keep your hands off her" is a cultural concept that our
society (among others) happens to be afflicted with.

I think you are confusing the capacity to do something with an imperitive
to do it. I don't deny that we're capable of getting angry, but we're also
capable of not getting angry. Both violence and nonviolence have cultures.
Violent cultures tend to focus on getting people who aren't mad, mad and
nonviolent cultures tend to focus on getting everyone to avoid being angry.

which will use them as it is accustomed to using them. Because of the
social implications of "function" and "purpose", we should avoid them
and use something else. Otherwise our lawmakers (who aren't terribly
scientifically literate like their constituents) are going to pass
legislation based on them.

Part of the problem is that it has become mixed in with misleading
metaphors and that old problem of design. You may not believe in
design, but it's lurking there in the semantics (as I have pointed
out many times before) and can sneak into your thinking without your
even realizing it.

Then there are no bastards in the world? :) No one lives to do it

The two examples are contradictory, incidentally. If it is genetic suicide
for me to do it, then reproduction is impossible.

I am not going to around with you on this. But such studies have been
done.

This is 1996. The situation in 1979 was maddeningly different. What I see
in many of your comments is that Gould's observations have been taken to
heart in the further development of the theory.

Whether the methodology is truly effective or not is another question, but
genetic fitness /has/ been a subject for manipulation by Western societies.
Here's a list of some examples which come right off the top of my head,
ranging from the innocent to the truly perverse:

* Eugenics clubs.
* Royal and noble marriages: only those of your class are worth mating
with. (Of course, this also creates a homogenous gene pool. If the
wrong trait creeps in, you're in big trouble!)
* Sperm banks which seek to store sperm from the best donors.
* Sterilization of mental defectives.
* The Nazi Lebensborn Program
* The Holocaust

Whether these were able to truly accomplish their objectives is irrelevant.
Most of them, I note, tend towards homogenous gene pools which we know are not
good in the long run.)

What is relevant is that all of these sought to create "bloodlines" (a cultural
term) which were in some way more fit from a standpoint of breeding. (another
cultural term which sometimes denote how one is reared and sometimes what one's
pedigree is -- probably a survival from a Lamarckian understanding).

The status in raising many kids is often nothing more than more hands
on a farm mean higher production and greater comfort for the /individuals/.
Rich people get to hire servants and eat the best foods, after all. In
agrarian societies, you can farm out your kids so that the surplus gets to
get a decent education and find a well-paying job upon which you can
happilly retire. This is one reason why birth control programs get
resisted in some parts of the world.
