Two years ago I started to learn (as self-education) evolution theory and neurobiology for to understand - who we are and where we came from? Now I see clearly that we are our brains, which are the result of RNA & DNA selection and replication.

Many of the issues now resolved for me: about love and intuition, origin of religion and art etc.

But one question remains "a mystery": why are there so many wishes, desires, urges?
What is the neurobiology base for a monstrous amount of consumer goods, objects of art etc.?

The most primitive idea is "complexity of brain -> intricacy of processes -> lots of desires".
Another naive answer has to do with so called "play-explore-investigation instinct", which plays an important role when two basic instincts are "still".

But to me, human wishes and urges look like more of a Akkerman function than just "a lot of".

I belive that (sooner or later) evolution and neuroscience will give answers to all questions about our mind and behavior.
So glad to hear something about this one!

Hadn't heard of Ackermann functions before...interesting concept. I'd love an answer to this too, but I'm a little pessimistic about seeing one without a narrower focus and more concrete definition of the question. –  Nick Stauner Jun 5 at 5:45
    
Do you mean "Why does a group of people have a lot of varying desires?" or "Why does every individual has a lot of desires?" –  SBel Jun 13 at 14:32
    
@SBel, in fact, I'm interested in both questions. –  lesobrod Jun 14 at 15:26
    
But social diversity (desires, forms of behavior etc.) is subject of ethology (as the base) and social science. It seems to me that complexity and branching of individual wishes could be explained with neuroscience. –  lesobrod Jun 14 at 16:05
    
@lesobrod, for an individual, how many desires do you consider to be too many? For example, for me, I don't think that I have too many desires. They are sex, food, and currently I'd like to learn about personality psychology. –  SBel Jun 14 at 16:16
