Monstrous: The Lore, Gore, and Science Behind Your Favorite Monsters — page 5 — THE SCIENCE OF THE MONSTROUS Millions of years ago your prehistoric ancestors roamed the open plains There were kids just like you They picked berries danced and drew pretty pictures on caves They had a blast hanging out at the local watering hole You might even know some people like that today always smiling and never scared or anxious about anything You know fearless people Yeah those people died Probably eaten by a saber-toothed tiger or bludgeoned to death by rivals while they were peacefully sleeping But that apprehensive cavewoman with her spear at the ready suspicious of every berry and with one eye open as she slept she survived She is your great-great-great-grandmother and probably a few more greats and she has passed down her lessons of survival into the most primitive parts of your brain fear keeps us alive The part of your brain that responds to fear has not changed since your prehistoric grandmother When you are scared an almond-shaped mass called the amygdala A activates a split-second Your ancestor who did survive Your ancestor who didn’t survive 6
