It is close to sunset when Brandon is hiking in the woods with his dog. The dog suddenly stops walking and starts to growl menacingly at something in the shadows of the forest. Brandon squints his eyes and tries to make out what alerted his dog. He tightens his grip on the leash and strains to hear any movement in the dry leaves. He can also feel his pulse increase, and his mouth feels very dry. Explain how each of the following concepts applies to Brandon's current situation.

Epinephrine

Peripheral nervous system

Occipital lobe

Natural selection
