The grandmother hypothesis suggests that women who live through menopause play an important role in the survival and success of their grandchildren. This concept is also known as the "maternal grandmother effect", or the "grandmother effect". Additionally, some anthropologists refer to it as the "reproductive conflict hypothesis", as it suggests that older women may compete with their daughters for resources and reproductive success. Other synonyms for the grandmother hypothesis include the "embodied capital theory", which highlights the valuable knowledge and skills that older women possess, and the "life-history theory", which focuses on the evolution of life-history traits in response to changing environments.
