Is the suggestion elites were controlling access to procreation? Maybe men were also just killing each other extra fierce in the land grab. Uncompletely uneducated speculating on my part.
Definitely a factor. As agrarian societies expanded into hunter gatherer territory they would kill the men and take the women. Agriculture did not spread because it was a better deal for the individual at the time, it spread because it could support higher population density and specialization, including a warrior caste. And thus was more succesful at conquering and holding land.
