High testosterone is often associated with shorter lifespan in mammals. However, you find a new species of mouse in which males live longer than females under field conditions. Which of the possible explanations below would NOT predict this pattern? Male-male competition often injures the participants. Females suffer costs of reproduction caused by the burden of milk production. Males, but not females, provide territorial guarding that improves the survival of their grandchildren. Females enter menopause and stop reproducing at age five, while males can reproduce until death.
