On May 20, 2001, The New York Times published an article about polygamy. "As the conviction of a Utah polygamist...reminds us, monogamy is not the only way to procreate. It's just a theme 'round which nature has designed many variations...Men are just 15 percent larger than women, suggesting [to some biologists] that 'mild polygyny' is the natural condition of the human species." Biologists also believe that a certain degree of polyandry may also be natural for the human species. "We have inherited our own version of the primate mating system, one in which both sexes possess an inclination to monogamy that falls somewhat short of total embrace."
