Fitness is such a mess of conceptual worms. I suggest a look at
Individual phenotypic "fitness"--success at surviving and thriving in
one's lifelong environment, especially a culturally modified one--is
not *obviously* linked directly to number of fertile offspring a
generation or two down the line. (Leaving aside individuals too
dysfunctional by genotype or accident to reach maturity.) It might
have been a million years ago, but how could we know that?
