It pains me to disagree with Anders, but then I don't entirely agree
with Rafal either.

Change group to gene please.
We can see two behaviors in chimps (xenophobia always on for the
males) and bonobos, (xenophobia off). What ultimately limits bonobo
populations is uncertain, but it does not seem to be groups killing
other groups off. For humans xenophobia on or off is situational. It
goes on instantly when attacked and somewhat slower when memes to
dehumanize the others build up in situations of bad times a-coming.

When it is (on the average) better for your genes to do so. That's
not hard to model and I have done it in the past here (Sep 30, 2012).

Gregory Clark discusses this extensively in his work. He makes the
case that the evolutionary selection pressures on the UK population
for the traits that make a person well off economically were as
extreme as the selection that generated tame foxes. (The children of
the well off survived the frequent famines that killed the children of

The work on foxes showed that 8 generation of heavy selection were
enough to make profound changes in social proclivities.
