It's very likely that aging is driven by some kind of scheduled gene program. It makes perfect sense to phase out individuals from a group-level selection point of view.

This would be an optimistic scenario and introduce a possibility for the "scheduled gene program" to be controlled or turned off. The current thinking in the field seems to favour the idea that aging is a complex combination of programmed changes, stochastic damage, as well as various adaptations to help cope with the damage.
