A society’s moral code is a Darwinian survival factor that can eliminate it.

Evidence

[M]orality and religion, as the organised expression of moral approval and disapproval, must be regarded as factors in the struggle for existence as truly as are weapons for offence and defence, teeth and claws, horns and hoofs, fur and feathers, plumage, beards, and antlers. The social group, community, tribe or nation which develops an unworkable scheme of morality, or within which those social acts which weaken it and unfit it for survival habitually create the sentiment of approval, while those which would strengthen it and enable it to expand habitually create the sentiment of disapproval, will eventually be eliminated. Its habits of approval and disapproval handicap it as really as the possession of two wings on one side with none on the other would handicap a colony of flies. — Ambedkar, B R, Annihilation of Caste_ The Annotated…, 1013
