[17] Female red-winged blackbirds (Agelaius phoeniceus) exhibit aggression toward other females upon intrusion into the harem, usually heightened around breeding season. Monogamy is an intrinsically unstable mating strategy. The Ecology and Evolution of Mating Systems. In elephant seals, the alpha male dominates the mating within the group. A wide-ranging song repertoire develops with age, and older males are more likely to dominate better territories, giving a plausible reason as to why females prefer older males. While some argue that polygamy can have certain benefits, such as providing a sense of community and support, there are also a number of disadvantages associated with this practice.

For some males, polygamy actually offers profound advantages. Fewer offspring are produced through this method, but their survival rate is higher than that for external fertilization. Sexual selection is the driving force that underlies the evolution of male competition and female choice, but what ecological factors contribute to one species having highly ornamented males and another having no differentiation between the sexes.Not all species show strong sexual dimorphisms. Social monogamy has both advantages and disadvantages for each partner. Traditionally marriages are known to occur between one man and one woman. From the point of view of evolutionary biology, having multiple partners also means greater chances of successful reproduction.
