Evolutionary biologists have argued the monogamy-with-cheaping is a standard human behavior. I do not mean to make you think that I believe that monogamy is "the only way", however, psychology plays a huge role in our sexual and social relationships. Many women prefer a more intimate one-on-one relationship, while men do not; or so it has been said. In evolutionary terms, a woman would want to give the man the impression that she'd never mate with another if he was gone or away. Whether that's true is a different question. I do not believe that all women want to cheat on their spouse. More data from a wider set is needed, and even then it is a matter of biology and social context; random chance. But don't assume that a society that overtly pushes monogamy will actually wind-up with husbands always fathering their official children. I did mean to imply that I did. It really depends on the social context and size of the group. A smaller group will be more apt to provide more intimate care than a larger group. It was not my intention to put the blame on the male gender by any means. Women and men have an equal role to play in the physical and mental rearing of any child.
