We all have a broad range of emotions. Am I correct in believing that each emotion has an evolutionary significance? If so is each of our emotions controlled by chemicals in the brain?

Hi, I understand that emotions are dictated both by environmental stimuli causing neurons in the brain to create an emotional response, and hormones. In addition to these two I personaly believe that some emotions may be purely caused by the soul.
One fantastic related book that I suggest you read is:
‘The expression of the emotions in man and animals’ by Charles Darwin.
He was sooooo ahead of his time!
I hope this helps a little!
Adding to my question. Are emotions caused by hormones, neurotransmitters, both or something completely different? Emotions do seem to have protective functions but we have dozens of specific emotions and we can’t have a different chemical for each one. It is difficult to understand how it all works.
