Statement A
Morality is an evolved repertoire of cognitive and emotional mechanisms with distinct biological underpinnings, as modified by experience acquired throughout the human lifespan.
Statement B
Morality is not the exclusive domain of Homo sapiens; there is significant cross-species evidence in the scientific literature that animals exhibit “pre-morality» or basic moral behaviors (i.e. those patterns of behavior that parallel central elements of human moral behavior).
Statement C
Morality is a “human universal» (i.e. exists across all cultures worldwide), a part of human nature acquired during evolution.
Statement D
Young children and infants demonstrate some aspects of moral cognition and behavior (which precede specific learning experiences and worldview development).
