The butterflies navigation is very complex. Wing design, magnetic compass and more! Is this a result of random mutations? Seems like a ridiculous idea when you read this article. Logic should tell us it is much more likely they were designed this way. Why? Because the butterfly is an organism that requires complex systems to work together to accomplish the goal of migration. Those systems have been engineered to work smoothly together. Random mutations could never create the amount of required new functioning genetic material needed for the instructions to build such capabilities because it has never been observed to create any at all.
