That's a hypothesis. Again, reproduction is happening prior to any potential partner even knowing of a grandmother in many places in the animal kingdom. Even for humans actually. So you're subscribing to the more adaptationalist line of reasoning for the existence of menopause. Which is fine. But you should concede that fact. Many others might subscribe to any of the other hypotheses for reproductive senescence. I subscribe to the artifactualist line of reasoning. ie - people just started living too long, and our bodies adapted for a 20-40 year life span. But there are numerous other hypotheses out there, many of them every bit as plausible as my artifactualist hypothesis. I only subscribe to the artifactualist hypothesis because it is the hypothesis most in line with the theory of evolution.
