>>143280> Humans haven't been monogamous until around the last few hundred yearsThis is false. Humans generally follow a mating strategy called serial monogamy, wherein the husband has a monogamous relationship with a woman, impregnates her, and stays with her for around 1-3 years after that, before finally leaving her for another woman. The social development of the nuclear family began with the advent of plough agriculture around 10,000 years ago. Having tons of one off sexual encounters with women is a bad sexual strategy because women hide their ovulation, which means you are usually wasting semen when you cum inside of the woman. The only way for humans to reliably have kids is to have sex with a single woman multiple times over the span of many days.
