Why is it important that the body have two control systems rather than one?
Well, our nervous and endocrine systems are there to differentiate the kinds of control, as well as provide different outlets for body control under different circumstances. Our neural pathways are a more instantaneous response system, allowing for immediate movement and reactions to stimuli. However, our hormones control growth and development, and while they are affected by the environment and can act immediately (epinephrine/adrenaline), this system is more of a passive, over time control of body functions. Without either one, humans would not be able to neither think nor grow properly. Only together are they able to shape a mere fetus into a human being capable of many things.
