Who invented monogamy and why?
Monogamy is one of several mating systems observed in animals. The amount of social monogamy in animals varies across taxa, with over 90 percent of birds engaging in social monogamy but only 7 percent of mammals engaging in social monogamy. With birds the locomotion method has meant that the sharing of genetic material with non-local sources is far less difficult, and reproduction is far more successful when both the male and the female contribute food resources to the offspring. The incidence of sexual monogamy appears quite rare in other parts of the animal kingdom. It is becoming clear that even animals that are socially monogamous engage in extra-pair copulations. more…….. http://www.answers.com/topic/monogamy It is due to animal nature which exists in humans. http://www.thefreedictionary.
