I would say that the evolved average lifespan was arrived at by
offsetting the human reproductive rate against the death rate, such that
we naturally live long enough (counting disease, accidents, and
predation) only enough to allow a stable population under normal
circumstances. Too long a natural lifespan, and we would have seen in
prehistorical archeological times, periods of population explosion and
contraction similar to the deer/wolf population interaction. As we can
see in the present, by technologically changing this dynamic, we are
risking our species survival because we are all living too long, and too
many of our children are surviving to reproduce...
If we wanted to evolve longer natural lifespans, we would have to have a
lower rate of reproduction, possibly in a lower average sperm count, or
in a longer menstrual cycle, or in an earlier onset of menopause. A
later onset of puberty would not be useful, as it would allow the
accumulation of greater resources by individuals prior to reproducing,
thus ensuring greater probability of survival of the next generation.
