Keeping to the OP subject, how does this work in human evolution?
[ what change should be made in individuals to better fit them for civilization?]
Whence? You don't inherit ethics; you learn them in youth or formulate them in adulthood. They're not genetically transmissible; you can teach your ideals to your own offspring, but they do not necessarily subscribe to the same ones when they grow up. They may improve on the ethics of their parents, but can just as easily go the other way. There is no natural selection for any particular ethic; which one confers an advantage depends on the culture.
Acquiring an ethic
Since that ethic has already been formulated - if not previously, then just now, by you - it no longer needs to come about through evolution.which acknowledges the autonomy of individuals, the diversity of their goals and interests, and their status as equal moral agents, free to pursue their various interests as they see fit, as long as they violate no one else's rights, and with no a priori obligations to pursue anyone else's.
How do you, individually, benefit from holding this view? How does it give you an edge on survival? Does it attract more and higher quality mating opportunities? How do your offspring benefit?
In brief: how does this ethic become the dominant norm?
And why, in the roughly 300 generations since the beginning of civilization, has it not yet become the norm?
