INTRODUCTION Such tensions could be avoided by establishing an official hierarchy between the women, or they could each run their household and thus live spatially separated. Stalk-eyed flies have eyes at the end of long stalks, and they compete for mates by measuring the distance between their eyes. Polygamy is often not a choice women or men have to participate in. In some species, including some fish, crustaceans, mollusks, and other invertebrates, there are environmental (water temperature, length of daylight) or biological (pheromones) cues that cause males and females to release gametes at the same time.

On the other hand, polyandry which is the least familiar type of polygamy is where a woman is married to multiple husbands. In species that mate via internal fertilization, its pretty obvious that multiple males cant mate with a female at the same time, and thus they must compete with each other. Systems where several females mate with several males are defined either as promiscuity or polygynandry. The most common polygamy, Provides a superior support system. Polygyny will occur when resources are localized and females form clusters, making it easier for males to control them. This can be a cause for abuse of power.
