Where do Darwinists get moral values?

Different lifestyles evolve different moral values. To hunters and
nomads, the whole world is free range, and all strangers are nothing
more than other prey animals.

To the yeoman farmers of temperate zone Europe and China, the need to
manage resources at a fixed location to endure the winter setup a very
different view of what we now call "property rights".

Tribes always had shamen and witches who raised the kids of
incompetent parents because the kids mite have the immune responses to
pandemics.

Barford, "The Early Slavs" shows us a yeoman farmer alternative, in
which a young couple would take tools and seed into the vast forests
of Europe, build a tiny log cabin, as we now say, "pioneer". they
didnt need strong immune systems. There was nobody around to give them
anything. what they needed was self control and good parenting skills.

There was no social safety net. You either put up the firewood and
food to survive the winter, or you died, and were out of the gene
pool. They are, of course, the ancestors of many of us, and we've
inherited many of their attitudes about self reliance and resource
management.

Which non-whites, other than temperate zone East Asians, have not.
Thus also, intermarriage between these groups at opposite ends of the
Eurasian land mass has worked out better. with similar moral values.
