The grandmother hypothesis is a theory to explain the existence of menopause, rare in mammal species, in human life history and how a long post-fertile period (up to one third of a woman's lifespan) could confer an evolutionary advantage.
Holding longevity constant, a female that undergoes menopause should have a lower total fertility rate, making menopause intriguing from an evolutionary perspective.
