Fear protects us
“People think being afraid is a bad thing, but the reason we evolved to be afraid is that the world is pretty dangerous and we’ve evolved very powerful systems that automatically force us to do our natural defensive and protective behaviors,” says Michael Fanselow, a UCLA behavioral neuroscientist.
Some fears are learned; others are encoded in our DNA: Rotting flesh (we’re looking at you, zombies), snakes, blood, heights — even our tiny-brained ancestors understood these were unsafe. And the fear prompted immediate responses, Fanselow says.
