But people never select for "good" elderly so to speak.
Neither do most primates or lions. The elders just happen to be there. So we can't really even say if it's just more elders in the animal kingdom making themselves useful. Which, again, is happening after reproduction typically.
For something to have an effect on reproduction, I would think it would need to be part of the decision beforehand.
