Reflex arcs remain more efficient for quick responses even after the evolution of complex neuron networks because they bypass the time-consuming cognitive processes of the brain. This enables rapid reactions to stimuli, particularly in situations where immediate action is essential.
Despite the evolution of complex neuron networks, why do reflex arcs continue to be more efficient for quick responses?

Despite the evolution of complex neuron networks, reflex arcs continue to be more efficient for quick responses because they operate independently of conscious thought and involve a shorter neural pathway. In reflex arcs, sensory information bypasses the higher brain centers, directly connecting to the spinal cord and triggering an immediate motor response. This simplicity reduces the time required for signal processing, enabling faster reactions to potential threats. While complex neuron networks are crucial for advanced cognitive functions, reflex arcs provide a rapid and pre-programmed mechanism, preserving valuable time in situations demanding swift responses for survival.
