While it may not be as socially acceptable among humans, a female choosing to take multiple mates is a common phenomenon in the animal kingdom. But why the practice of polyandry (a female having more than one male mate at a time) is so prominent is still a mystery in most species.

Most theories predict that taking multiple mates would be risky for a female without adding benefits. However, new research finds that in gray mouse lemurs, a type of small primate from Madagascar, healthy females seek out multiple mates in the few hours of one night they are receptive to mating every year. These multiple mates must confer some kind of benefit to the females, though exactly how they benefit is unknown.

“Males get benefits from mating with multiple females, because they can impregnate multiple partners,” study researcher Elise Huchard, of the German Primate Center in Göttingen, told LiveScience. “In most species, females only have a few oocytes [eggs], so mating with multiple males will not increase the number of offspring they will have.”…
