Religion, moral and values.

[Tellos Athenaios]

From a biology perspective, morality is defined by a collection of guidelines which evolved as [our] ancestors did passed down through the generations from parents to offspring. The framework demarcates more or less where collective interests trump those of the individual. Incidentally, such a framework of behaviour (moral = good, not moral = bad) which is enforced by a broader society is not exactly unique to the human species.
