Social monogamy in mammalian species was significantly lower in monogamous species than in polyandrous ones. However, there still needs to be more empirical evidence in order to further test this hypothesis.

Monogamous males tend to be smaller compared to females, which results in sexual competition between the male candidates for a larger female. Comparing to monogamous species, polygynous species tend to display more sexual dimorphism, or difference in body size; it is believed that sexual dimorphism could be an evolutionary consequence
