The theory of evolution is the theory of the survival of the fittest. No superior entity regulates evolution. Evolution itself is blind, deaf and dumb and all what we see today is the outcome of the survival of the fittest.
So why was it so beneficial for humans not to live much longer than 75 years ?(of course there are exceptions, we all know that, on either side of the scale).
Quoting: Tekunda What part of "pass on that advantage to their progeny" do you not understand? Once a human reaches menopause, nothing in their life will have a genetic impact on their direct progeny. (I do have to add, that since humanity is a social animal, there is possible evolutionary advantage to the breeding pool from healthy post-breeding individuals. So selection remains operative, but within the limits that those individuals perform a useful surface to the social group as a whole).
