Why do animals (and us) have them?

Is it contigent upon intelligence? A byproduct of intelligence?

It's a method DNA uses to survive and reproduce.


Is it contigent upon intelligence? A byproduct of intelligence?
I'd keep it distinct from higher reason, but it's a form of intelligence. It yields wise survival behavior. It is an input to reasoning, for those that can.

Emotion is primarily centered in the brain's limbic system, with the reasoning neo-cortex layered upon it. Evolutionarily, emotions came before reasoning.

It may also be a form of communication, a way for organisms to modify their behavior in such a way that their companions can get an idea about their internal state. If it was purely an internal cue, then you would think there wouldn't be any external representation. However, most emotions tends to be accompanied by stereotyped external behaviors that are universally recognized (sometimes even between species), so that would indicate that the emotions are at least partially meant to communicate information to other members of the species.

Emotions relate to a primitive [and 'lower'] part of the brain called 'limbic system'. Some call it 'reptilian brain'. Mammals have inherited it along the evolutionary chain. It is only tangentially related to intelligence for playing a role in the formation of memory.

All violence, agressiveness originate there.
