Artificial Evolution (ONS-67) is a blue instant from the Onslaught expansion that lets you replace every instance of one creature type word with another (other than Wall) on a target spell or permanent. The chosen replacement is applied to all printed text and the type line and lasts indefinitely for that object, but it does not change dynamic effects or tokens already altered. This can be used both to remove or add creature types for synergies, or to disrupt cards and spells that care about specific creature types.
