The "sexual revolution" entailed males first competing with other males for dominance, as a way to get matings. However, low-ranked males—and eventually all males except those with the highest societal stature—began supplying females with provisions in what is called "food-for-mating" to get a leg up on the competition. Females showed preference for the "provisioning" males, leading males' energy to be spent on providing for females and females becoming increasingly faithful. This spurred self-domestication and the modern family as we know it today.One cannot help but wonder if this change coincided with the expansion of the braincase that began to take off around 1.5 million years ago, the time in which we first encounter stone tools and the first inferences of some form of rudimentary culture. With the increase in the strong pair-bond, you have the basis for providing the offspring with the stability of a strong nuclear family. This, then appears to be the natural order of things. It is ironic that this nuclear family structure has, for many aspects of western society, broken down in recent years in the face of “free thinking” and lack of personal responsibility.
