Re: Hardwired?

Nevertheless, monogamy, or at least social monogamy, does exist in many societies around the world[46]),

Eurocentrism much?

There is a clear chain of causation (historical, not biological) here:

Greek monogamy -- Roman monogamy -- Christian monogamy -- European peoples and Westernized descendants diffuse monogamy to the rest of the world.

By 1500, polygamy (polygyny) was still clearly predominant worldwide.

By 300 AD, monogamy was only predominant in the Greek and Latin Roman Empire.

By 800 BC, you'd be more likely to believe that the Greeks would adopt polygamy than that the Jews would adopt monogamy. It would make more sense, if you lived at the time, to predict the switch in this direction.
