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!
