The human appreciation for art in all its forms doesn't have - to my knowledge - any survival value, so I am at present assuming that there's more to the story than just biology.
A quick note on this:
(Apologies: I have nothing, no articles or anything, to back up what I'm about to say. This is all from memory.)
Certain things that humans crave fall outside of survival value, but are still related to it. For example: we crave sweets and fats and this guides us to eat what our bodies need. But there are certain tastes and smells that trigger this to an extreme, beyond survival value, but they stem from those same nerves. Example: cheesecake is fatty and sugary and super delicious, and with no knowledge of nutrition, one might be compelled to eat only cheesecake over a more nutritious but less stimulating food.
This impulse to be attracted to super-stimuli (a word that I may have just made up) can extend to all of our senses. Certain sounds are more or less desirable for survival reasons, and so a sonic super-stimuli like music would be like cheesecake for the ears. Likewise with visual art, where we are attracted to certain angles and colors for survival reasons, but a particularly aesthetic painting might be like eye cheesecake.
Of course, this is just theoretic, some food for thought. Many evolutionary ideas are not falsifiable, and this idea certainly falls under that category.
