You're talking to the guy who was writing about this since the mid 1980s.

It's a bit hard to figure out how far back language came into play, though
genetic clocks on the area of the critical genes might give us a rough
date. But certainly written language came too late to have had a lot of
influence on hunter gatherer selected "morality" mechanism genes. Possibly
even spoken language came too late.

True. Consider Shakers and Mormons.

I wish you would provide some examples where this happened. I just can't
get a grip on what you are saying without examples. Perhaps from "Guns,
Germs and Steel"?

Most of our evolution took place before agriculture when "culture"
circulated in the hunger gather band or at most a bunch of related
bands. If the few remaining examples of hunter gatherer life can be
extrapolated to the bulk of human evolution, then while violent death was
common, putting a band member to death for "crime" was rare. I would say
the very concept of crime comes way too late to have had much influence on

If you used the term "political correctness" instead of "morality" I would
be more likely to agree with you.
I think the mental mechanisms that underlie our (flexible) sense of what is
moral are the result of stone age selection and are not going to be changed
The flexible part comes from environmental conditions. It is not
considered moral to steal or murder, but as we saw about a year ago, it
only takes a few days before people get hungry enough to steal and not much
more before murder would become common.
