The Webster's Unabridged is an authority on how words are used in common language, not an authority on how words should be used in a science context. Perhaps you should give up this 'argument by dictionary' before you put your foot in it.

To put it more simply, the Dictionary reflects the language, the language does not reflect the dictionary. Words in common usage seldom reflect their technical usage.

Anyone with even a small understanding of Evolution and its relation to genetics would understand that de-evolution, or devolution as some say, would take a reversal in the sequence of mutations and selection that occurred in the originating evolutionary path. De-evolution is used in common language by those with little understanding.
