>>13064210socially monogamous means father and mother take have long term commitment with their children, not necessarily genetic lifetime commitment or the conservative idea of nuclear family. if you look at the bigger picture most humans have historically breed via this form. you can say humans have less strict social monogamy
btw polygynous species have much higher sexual dimorphism due to sexual selection, humans have the lowest sexual dimorphism among all primates. it doesn't make any sense that the species with the highest parental investment and most complex learned behavior by miles isn't socially monogamous....
