dna has its expression in our physical bodies our minds and their design and our extended phenotype which is: our changed environment which we have fashioned as a result of our minds and bodies' activities over generations all of this has been directed for survival of dna though we have been unwitting players in this
now it seems there is a flourishing of interest in the west about how our minds and emotions work this is in the ambit of the extended phenotype that is: dna still expressing itself possibly the west's new interest in the understanding of mind and emotion is another move on dna's part: failure to understand emotion properly has brought us to the brink of annihilation because of destruction, competition, war or terrorism related to environment, religion, resources, ideologies.
all of these juggernauts of destruction are fueled by one thing: emotion in the case of resources and environment the emotion is greed and hunger for power
in the case of ideologies and religion the emotion is power, revenge or arrogance but all of these emotions are simply related to the one final emotion happiness or any similar word for positive emotion
in all cases emotions is the baseline driver. possibly, with a great deal of luck, the phenotype for survival is going to change so that instead of being driven by emotion unwittingly, we come to know the relentless power that emotion has wielded over us since caveman days. then by knowing how our neural networks have all along been directed, we could come to avoid these dangers by understanding. this would be a meme of emotional understanding as a paramount human skill set
this would appear to promise better survival of dna and more happiness for individual humans. whether survival selects for this or not remains to be seen.
