For example, the adrenal glands of all animals have evolved to pump out stress hormones in unexpected situations — the hormones spur action and increase fuel to the brain, helping the animal react to danger appropriately. Those hormones also flow to memory centers in the brain, to help the critter remember those notable moments and places.
