Why Some Animals Swarm

I'd never thought about it before reading this article, but it makes sense: animals evolved to swarm because swarming confuses the predators and allows more of the prey to escape (and hence survive, to have more offspring).  Like all things evolutionary, a random mutation at the DNA level must've led some animals to react that way when predators approached, and because it worked better than the usual "run away!" instinct, it eventually became a new trait, over generations.

I love how the universe always makes more sense when you view it through the lens of evolution!  I can't imagine how people who don't believe in evolution ever make it through life.
