Why Every Human On Earth Fears The Dark

You walk a little faster to bed in the dark and you know it. Here's the unsettling reason why: you were never actually afraid of the dark, you're afraid of what used to hunt you in it, and your brain is still running the survival program tens of thousands of years after the threat disappeared. This is the story of how humans became prey, why lion attacks in Tanzania follow the phases of the moon, why fire became civilisation's first nightlight, and why the shape you see in the dark corner is your own brain drawing a monster. By the end you'll understand exactly what happens in the half-second after you turn off the light, and why that little jolt of fear is the oldest, most loyal part of you, still keeping watch. #fearofthedark #evolution #psychology #brain #sciencefacts
