on #3 i suspect that if the women are chosen with even a moderate amount of care they can/will find at least enough common ground not to be at open warfare. From a biological standpoint, the reduced likelihood of renewed sexual activity immediately after childbirth would possilbly contribute to slightly lower illness from post birth complications, and reduce the likelihood of dying young from too many children too fast. There's also the fact that genecically speaking if there is someone else to care for your children even if you die young, your genes have a higher chance of spreading beyond the current generation.
#6 Is i suspect a case of reinventing the wheel with a new name. It's been known for years that in times of stress more boys are born. I suspect that the causes of this are: Less attractive people are in more stress about their relationship, if they are attractive they _are_ treated better (see the studies on sentancing of attractive people vs unattractive ones, and also the ones on pay) and _know_ they are getting treated well and are hence less stressed.
