Sapolsky's column in the September 6th-7th edition of The Wall Street Journal is titled "Sperm Can Carry Dad's Stress As Well as Genes." If I am following him correctly, Sapolsky is asserting that "behaviors" can be transmitted to the next generation, so that you not only inherit based on the DNA you receive from your parents; you inherit based on the behavior patterns your parents pursue.
In my Two Worlds model, that seems to say that "our" world, which we create by our own actions (you could call them "behaviors") can modify the World of Nature, at least to the extent that future generations may be "changed" from what genetics might otherwise dictate, based on "the environment." As Sapolsky puts it: "The environment can alter biology with multigenerational influences."
For good or ill, that seems to elevate the importance of what we do in the human world for which we are directly responsible.
Maybe the outrageous willingness of human beings to perpetrate violence on others is not the result of a "biological determinism" that can never be escaped.
That could provide a bit of hope.
