@brigrammer @Nils biological changes from brutal selective pressures, except cannibalism which is already very narrow either eating family members(only piecies i think) in a funerary practice or eating pieces of respected enemies, given that its so narrow its hard to say there was a change could be more gore aversion rather than a special aversion to cannibalism

infanticide was often practical, abandoning them in the woods would be more romantic


"murder" no one would kill someone for disagreeable reasons thats a barbaric thing of the past 🙄

human sacrifice is usually criminal or pow execution, injuns liked to turture them to death instead

many of these features exist now, many historically reoccur, theres no reason to assume a default only a ready ability to have those traits, again "culture" pointless grasping at an external thing, different people different generations different sub races there is ample innate variation to provide explanations culture is just something more complicated
