I would wonder if the question is different for men and women.Women would achieve the most "reproductive success" by having a stable home environment, and help with providing for and raising the children. Pregnancy, of course, involves a large investment of energy, and in the past, it was dangerous.For men, while the above may be good, they would also achieve reproductive success by spreading a few extra wild seeds around the neighborhood.
I'd like to know the figures for the average age of people when they get divorced. Perhaps biology favours monogamy up to a point, then the curse of longer life spans set in and the "need" for monogamy fades.

Perhaps biology favours monogamy up to a point, then the curse of longer life spans set in and the "need" for monogamy fades.Supposedly the romantic crush phase of a relationship with lots of related circulating hormones lasts about two years, long enough for like 95% of fertile couples to conceive. I've read there is a big spike in divorce rates at about the 4th year of marriage.
. My bet is that far more women will contend that monogamy is the natural order of things.
As with other herd animals, the only way that a male can be most assured that an offspring is his own, is to pair with more females. For females, there is the assurance that 100% of the time, their offspring carries forth their genetic heritage.
