Gary Marcus on Charles Darwin's 'Survival of the Fittest' -
FEBRUARY 11, 2009 WSJ op-ed by Gary Marcus

Neither evolution nor Darwin ever promised anything like perfection.
Evolution is not about creating perfect or optimal creatures, which
would require forethought, but only about the fact that the genes of
creatures with modest advantages ("fittest" among those that happen
currently to be alive) tend to spread throughout the population.
Darwin's theory of natural selection tells us that a one-eyed creature
may outcompete a blind creature, but that doesn't mean that a creature
with two eyes couldn't come along later.This seemingly subtle difference
-- between "fittest among the choices that happen to be lying around"
and "fittest imaginable" -- makes all the difference in the world.
