Very clearly according to scripture, man's nature is not an open question but a given fact from God.

This is a fact of central importance. Man was created into maturity. As a result, the key command is not child psychology, or animal psychology. Evolution cites that man must be understood in terms of the child, the child in terms of an animal ancestry, and the animal ancestry as an emergent out of chaos!
