The compensating tendency of the evolution system to evolve superior organisms, which in one way or other "will escape the parasitic invasions," by becoming less liable to them, and so to diminish the damage done, as a sum total, finds a corresponding result in the system of special creations by a different process and at a more rapid rate. For the hypothesis of special creations, rightly regarded, does not assume the special creation of each individual animal as a miraculous or semi-miraculous interposition of divine power; and even when we apply it to the lowest types of animals it implies only the formation of that type with the power in most cases of continuing its species. Assuming the parasitic animals to be in this sense special creations, the superior organisms on which they prey during their existence may become less liable to their invasions by an infinity of causes which will diminish and finally put an end to the parasitic ravages. In the progress of medical science man may be wholly relieved from the worst and most obscure parasites that have ever infested him, without waiting for their evolution into some other type of animal that does not desire or need to prey upon the human system, or without waiting to have the human organism developed into one that will not be exposed to such causes of suffering or death. We know already that very simple precautions will ward off from man some of the most subtle of these enemies; and even in the case of animals lower than man we know that instinct teaches them how to avoid the ravages of some of the parasites to which they are exposed, even if there are others which they can not now escape.
