[ExI] Origin of ethics and morals

[Keith Henson]

Related to recent discussions, ethics and morals come out of
successful evolutionary strategies (where else could they come from?).

That means they were mostly formed when humans were hunter-gatherers,
living in small tribes or bands.  They are also conditional, since
external conditions determined how one tribe interacted with another.

Then recently some of our ancestors were heavily selected for economic
success.   (See Gregory Clark's work.)

Unfortunately this is mostly descriptive rather than proscriptive.

Still, understanding the evolutionary forces that shaped what we
consider to ethical and moral might help analyze proposals to change
things.
