There is the curious case of human menopause and grandmothers. Most species procreate young until death. But humans specifically have woman productively live raising grandchildren 10-20 years after losing fertility. Not quite sure when this evolved, but over a hundred thousand years ago.
I think one of Goodall's original female chimps is still popping them out every 3-4 years at age 50, if I am not wrong.
