The origins of monogamy

Interesting! American author Christopher Ryan and his theory of how monogamy started:
Before the advent of agriculture, monogamy simply wasn’t in the best interest of the individual or the community. In pre-scientific hunter-gatherer society, children were seen as much more communal – the connection between sex and birth had not yet been made. Once agriculture was in the picture, domesticated animals began to illustrate the link between sex and birth – and with that came the significance of propety and ownership. Only then did humans both know where babies were coming from, and have the incentive to know whose babies belonged to who. In order for each individual to know which children he should leave his land to, he must know which children were his– and thus, he must control who the women were sleeping with. And so, with the possession of land came the possession of female sexuality. That’s when this hunger to control female sexuality really entered human behavior. Before, when property is shared, and property wasn’t really even an important concept in pre-agricultural society, why would you care who a woman’s having sex with?
