I suggest you read the wikipedia link? The terms higher and lower are, as far as I understand, mostly just there for classifying the amount of complexity present in an organism - there's not some "these organisms are better than these other ones" thing going on.
Unless you mean something entirely different than what most people mean when they say "devolution", what you are referring to is just evolution. The same way that "reverse racism" is just racism.
