Your entire post was excellent--I'm not sure the MoQ Discuss can improve upon it.
Except, I do disagree with the part quoted above. "The survival of the fittest" is not
a tautology nor was it meant to be one. First, consider the individual case:
A mountain goat that is sure-footed is fitter to survive than one that is not.
But that does not mean an unexpected avalanche cannot kill the former
but not the latter. So it is a contingent (not necessary) matter whether the
former out-survives the latter.
Instead of individuals, let's look at the trait of "sure-footedness":
Having the trait of sure-footedness makes it more likely that the individual will
have reproductive success (the ram has better mounting ability),
so it is expected that the proportion of the population
that are sure-footed goats will increase over time. But again, this is a contingent
matter, though the odds favor it.
