AJ, agreed. The following quote from that paper exactly describes my position on the source of morality/ethics/norms:
“The natural selection of cultural rules is another instance of spontaneous order. Hayek contends that cultural evolution proceeds through a group selection process in which rules conducing to productivity spread at the expense of less-efficient practices. A group that observes better-adapted rules can support a larger population, so its practices displace other practices as it grows and as members of competing groups adopt these more effective behaviors.”
