The moth's ability to hear the bat is possible thanks to a complex se-
ries of processes. If you do away with any one—the perceptual differ-
ence between the A1 and A2 fibers, for instance—the moth will be

unable to distinguish the direction of the bat squeaks. Or if the struc-
ture of the ear membrane is defective, the moth will be unable to hear
anything at all. But on its own, a moth's ability to hear the sounds
emitted by bats means nothing. In order for the insect to survive, it
must have a nervous system that can respond to a predator's presence.
And in that nervous system, the reactions that let enabling the
moth to escape by setting specific muscles into action, need to take
place in order. That nervous system must be fairly complex to convert
the specific data of the bat's squeaks into a flight response.
Considering this system, once again we see the irrationality of ev-
olutionists' claims regarding evolution over the course of time. The
theory maintains that living things emerge only as the result of ran-
dom changes. Yet the moth's auditory system possesses irreducible
complexity. In other words, its hearing system can function only if all
its components work as a whole. The absence of just one component
or its failure to function
properly means that the
entire system will be

useless. Therefore, the
evolutionists' concept
of "chance" has no va-
lidity.
Most of the systems
and organs in living
things possess this
