Moral Laws Were Born To Facilitate And Advance Social Bonds

Morality has evolved with our species because of humans' practical and psychological need for social bonds, but even early human societies began codifying a morality into laws and norms that were meant to be applied universally.

The evolutionary origin of morality is coordination or cooperation to help people get onto the same page by pointing to common normative principles that we can use to negotiate relationships, to organize interactions across many different social contexts.
