As for using evolution to enhance the psychological well-being of patients, it has been done before. I know it has been done for panic attacks.
DOC: what's your problem son ?
PATIENT: I'M FREAKING OUT ! !
DOC: relax, we arrived here naturally.
PATIENT: gee, doc, i feel sooo much better.
ask any doctor (your personal physician perhaps) if they use the theory of evolution in their daily practice.
