emotions and the I-function

Submitted by Crystal Leonard on Thu, 02/12/2009 - 9:30pm.
Presumably, emotions are part of the I-function. While the purpose/utility of the sensory and motor boxes in the nervous system is very apparent for the survival of an organism, it is less clear for emotions. Emotions are obviously a result of evolution because "lower" organisms don't seem to have them. When organisms evolve the physiological changes are usually ones that benefit the organism. What physiological changes happened to the nervous system to allow the I-function to generate emotions? And why were these changes beneficial enough to have caused the evolution of emotions in animals?
