Butterflies Keep Using the Same Superpower Recipe for 120 Million Years

Scientists discovered something wild: butterflies and moths that aren't even related to each other have been using the exact same genes for over 120 million years to create their bright warning colors! Instead of inventing new genes, evolution just switches these special genes on and off in different ways, like flipping light switches. This means nature might follow a secret recipe book when creating life—how cool is that?
