Maintain Monogamy or Practice Promiscuity

What swamp are Joel and Trent wading into this time?  They discuss human evolutionary programming in the realm of sex.  Are humans wired for monogamy or non-monogamy, or is that the wrong way to even construe it?  Joel and Trent, respectively, make a case for monogamy and non-monogamy.  They also discuss the anomaly of the Mosuo people and the problems with the standard, transactional narrative of human sexuality.
