I like the "could really change how humans see the world and how we conduct our lives" idea.  But, "programmed by natural selection", with inevitably "laws about property, rules about incest and marriage, customs of taboo" is less appealing, for me at least.  Perhaps "human nature," the brain's way, is as much about differences as about similarities, with differences being the grist from which new as yet unconceived possibilities arise?   Cf Variability in brain function and behavior and Noise in the nervous system.
