One is tempted to disgress, [tr. note: sic] for a moment, from the subject at hand in order to draw, from this incident, an argument for the Christian Day School; but we shall desist. The quotation is here adduced to illustrate the vogue which evolution, specifically Darwinism, still maintains in the literature, even in the school-texts of our day. Babes and sucklings are introduced to the theory of evolutionary development, and the theory is presented with an assurance as if it were scientific truth. The words of Agassiz, prince of naturalists, apply to-day. "The manner in which the evolution theory in zoology is treated would lead those who are not special zoologists to suppose that observations have been made by which it can be inferred that there is in nature such a thing as change among organized beings actually taking place." He adds: "There is no such thing on record. It is shifting the ground from one field of observation to another to make this statement, and when the assertions go so far as to exclude from the domain of science those who will not be dragged into this mire of mere assertion, then it is time to protest." Dr. J. B. Warren, of the University of California, more recently said: "If the theory of evolution be true, during the many thousands of years covered in whole or in part by present human knowledge, there would certainly be known at least a few instances, or at least one instance, of the evolution of one species from another. No such instance is known. Abstract arguments sound learned and appear imposing, so that many are deceived by them. But in this matter we remove the question from the abstract to the concrete. We are told that facts warrant the evolutionary theory. But do they? Where is one single fact?" The hypothesis assumes that through environment, certain varieties of species (both of plants and animals) arose, and that the varieties best fitted, through their habits, structure, or color, to maintain themselves in the struggle for existence, survived the species less favorably endowed, and hence persisted. (We have quoted in our initial chapter the classical illustration of the dipper-birds from Wallace's _"Darwinism."_)
