Final answer:
Females may choose polygyny for reproductive and economic benefits, such as access to a genetically fit male in a resource-rich territory and creating a strong labor force with multiple wives.
Step-by-step explanation:
There are various reasons that females might choose polygyny, which is a mating system where one male mates with multiple females. One reason is that females can benefit by mating with a dominant, genetically fit male in a resource-rich territory. This ensures that their offspring have a high chance for survival even at the cost of not having male help in caring for the offspring. A second reason is economic advantage; in societies where polygyny is practiced, it can provide greater economic opportunities for family members. For example, multiple wives can pool together a stable labor force with individual skill sets, contributing to the family's collective success.
