That’s plausible, but there might be trade-offs involved. There’s a theory — not sure how serious it’s taken by experts — that at least some of the mechanisms involved in aging have other benefits. For example, the fact that telomeres limit the number of cell divisions might also be a defense against cancer. A mutation that increases lifespan at the cost of this mechanism could be a net negative, from an evolutionary point of view.
