Given the interaction of natural selection, mutations and genetic drift, do you expect
a population's fitnesses to be optimal, near optimal, or far from optimal? Why?
Near optimal, because natural selection removes deleterious mutations but mutations
and genetic drift keep reinjecting deleterious mutations.
Optimal because (in a large population) natural selection removes deleterious
mutations.
Far from optimal because mutations inject deleterious mutations and genetic drift lets
those mutations drift to fixation no matter the population size.
