has given man flexibility, but in doing so, it has robbed him of ( 1 ).
The behavior of creatures lower (A)(the, scale, than, down, evolutionary)
ourselves is often largely governed by pre-programmed patterns. Some of these
patterns, like the display of the bowerbird, or the hunting habits of wasps,
are beautiful and elaborate. So long as the animal follows these age-old
patterns, its behavior is fitted to the environment as closely as a key fits
a ( 2 ). If the environment remains constant, the animal's basic needs, for
survival and for reproduction, will be provided for in a more or less automatic
fashion. But if the environment changes, the animal whose behavior is governed
by pre-programmed patterns is at a ( 3 ), for it cannot easily
