Multiple mates good for both sexes
An Australian experimental evolutionary study on house mice (Mus musculus) has found multiple mating is beneficial for both males and females. The study, in its sixth year running, has found that polyandry drives increased embryo viability in a vertebrate and that the risks associated with multiple mating were far outweighed by the benefits.
