The way they raise young would tend to change, as well, and I do mention that both parents could care for the young together. But, in any case, the real stumbling block for an older octopus to have worth is to find a scenario where they help more offspring survive into the next generation. | |

If the population remains the same, in an environment with parents and even grandparents, then less young would have to survive into the next generation. Evolutionary forces favor more offspring surviving, which is why the adults die now. | |

Perhaps the babies stick around until maturity, assisting with raising the next cycle, and learning lessons from mother. She could similarly remain useful post-reproductive age, as human and elephant grandmothers do. Anyway, the maximum population is fixed, regardless of mating strategy. | |
