Of course, reflex arcs have evolved in animals because the thinking

process of the brain is not fast enough. In fact many animals have very

little or none of the complex neuron network needed for thinking. So it is

quite likely that reflex arcs have evolved as efficient ways of functioning

in the absence of true thought processes. However, even after complex

neuron networks have come into existence, reflex arcs continue to be

more efficient for quick responses
