Conflicting statements in the bible

[Statler Waldorf]

I don't know if it's a moral obligation or not. It may simply be a conscious application of the instinctive drive to survive and propagate a species.

So anything that helps the species survive and propagate is moral?

I think the only moral standard(s) that would be applicable in all circumstances is that which promotes the continued survival of the group. As the group becomes more safe and secure, they can place more import on social behavior beyond that needed to ensure their survival.

Ok, why is continual survival of the group the ultimate standard?
