The Real Reason Humans Fear The Dark

Your fear of darkness may be millions of years older than you think. The unsettling feeling you get in the dark began long before cities, language, and recorded history. Evolutionary psychiatrist Randolph Nesse helped explain why human alarm systems often overreact to uncertainty. • The reason human eyes struggle after sunset. • The predators that shaped ancient human behavior. • The evolutionary logic behind false alarms and fear. • The surprising connection between imagination and darkness. • The invention that allowed humans to fight back against the night. By the end, you will understand why darkness feels threatening even when you know you are safe. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SOURCES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HUMAN EVOLUTION AND NIGHTTIME RISK Richard Wrangham, 2009.Catching Fire: How Cooking Made Us Human.Basic Books.
