It certainly doesn't produce a hardier organism.
With respect, MA, this is nonsense.
If we were faced with a race for survival between the sexes, the greedy, aggressive, selfish, fast-living risk-taking, male genotype would dominate for the first 20 or 30 years.
The greater longevity of the female genotype would not become relevant until after 40 years or so.
( I think Harlan Ellison wrote well on this - "One man and his dog" )
Fortunately, it's not (completely) a race, and (some of) us can still see value in each other, otherwise neither sex would be here...
