That's not an advantage to short life; it's an advantage to
early reproduction. It causes short lifespan only if early
reproduction and long life are somehow incompatible. In that
case, the incompatibility itself is the main casue of aging
- the tradeoff alone creates aging. The value of recombination
per se would only make a substantial difference for organisms
in fierce coevolutionary struggles (Red Queen races).
