Go one further -- drive over it in your car -- and that won't cause the critter any trouble at all, either. Its exoskeleton is one of the toughest in the animal kingdom. And scientists now believe they know why.

But lurking beneath its humdrum exterior lie a few structural marvels, built by evolution. Many species of beetles can fly an...
