From whence, then, comes emotional response?
Further, why is there emotional response at all?
What adaptive purpose does emotional response play in evolution?
Even further, explain the adaptive purpose of spirituality in evolution; do other creatures have spiritual experiences?

From the brain. The heart has nothing to do with it.
> Further, why is there emotional response at all?
Basic emotions are useful survival traits. Fear keeps you alive, anger defends your young, love keeps you with your mate and your young, etc. Humans, having evolved intellects rather more advanced than the norm, also evolved more complex emotions than the norm.
> Why do human beings have spiritual experiences?
One possibility: the universe is extremely complex and chaotic, and not at all set up to make life easy and comfortable. Spirituality may well be simply a means by which humans rationalize such complexities.
> do other creatures have spiritual experiences?
Dogs sure seem to.
