If morality is imprinted by god into the hearts of man, why is it that feral children adapt the morality of the host species? (so much for god imprinted on the hearts of men) Not only is such social behavior learned, but it is rarely unlearned, with the vast majority of these kids becoming institutionalized after capture—even after being baptized by the well intended, they remain in their adolescence mindset, be it wolf, monkey, antelope, or bear. 
Interesting side note; feral children also develop the acute senses of their host species. Nocturnal vision, acute hearing, and sense of smell are all superhuman compared to the tame man, showing adaptations develop much more rapidly than one would expect.
