IRRECONCILABLE DIFFICULTIES CONNECTED WITH EVOLUTION
§ 1. Preliminary Remarks.
THE DOCTRINE OF EVOLUTION.
General views of the development or evolution of the visible order of nature have been entertained by philosophers from the earliest historical times. There were pioneers of Evolution from Thales to Lucretius (600 B.C.–50 A.D.). The inquiry was then arrested for nearly sixteen hundred years—that is, until the renascence of Science. As knowledge, in spite of ecclesiastical discouragement, again slowly advanced, the science of biology gained in strength, and the work of Linnæus, Buffon, Lamarck, Erasmus Darwin, and others, paved the way for that modern theory of Evolution which Darwin, Wallace, Spencer, Huxley, and Haeckel have demonstrated to us. This doctrine of Evolution is no longer a mere speculative theory, possibly or probably true, but an established fact accepted by the whole scientific world with hardly a single dissentient voice. We know that everything as it now exists is the product of Evolution—the solar system, the earth, all lower forms of life, and lastly man, together with his languages, arts, sciences, theology, social habits, instincts, and, according to many high authorities, morals, conscience, and consciousness. Yes, “man, perfect as he may appear to us, is still not a being apart in nature, but by his whole organisation is continuous with the other zoological species.” “Anthropology, properly so-called, is, in fact, merely a chapter of zoology.” “The homological structure of man, his embryological development, and the rudiments which he still retains, all declare in the plainest possible manner that he is descended from some lower form.” He “derives his moral sense from the social feelings which are instinctive or innate in the lower animals.”[1]
It is in the special sense of explaining how living things came into being, and how they have acquired their present characters, that the teaching of Evolution appears to be most in conflict with that of the Churches and the Bible. It is, therefore, this aspect of Evolution with which we are here chiefly concerned, and we may remember that, since Charles Darwin published his Origin of Species (1859) and Descent of Man (1871), his main conclusions have been confirmed by every branch of anthropological research—by palæontology, zoology, comparative anatomy, physiology, pathology, teratology, psychology, and more especially by embryology, a science in which there has been a remarkable progress during the past thirty years. Professor Haeckel points out on page 24 of his important work, The Evolution of Man (translated by Joseph McCabe), that “even when human anatomy began to stir itself once more in the sixteenth century, and independent research into the structure of the developed body was resumed, anatomists did not dare to extend their inquiries to the unformed body, the embryo, and its development. There were many reasons for the prevailing horror of such studies. It is natural enough, when we remember that a Bull of Boniface VIII. excommunicated every man who ventured to dissect a human corpse. If the dissection of a developed body were a crime to be thus punished, how much more dreadful must it have seemed to deal with the embryonic body still enclosed in the womb, which the Creator Himself had decently veiled from the curiosity of the scientist.” Palæontology is another very young science that has contributed greatly towards the evidence of our origin. Professor Huxley informs us, in his essay on “The Rise and Progress of Palæontology,” that the first adequate investigation of the fossil remains of any large group of vertebrated animals dates from 1822, and that in the last fifty years the number of known fossil remains of invertebrated animals has been trebled or quadrupled. Fossils were at one time believed to have been sown by the devil, whose fell purpose was to throw discredit upon the Bible story of Creation. Perhaps this pious opinion may have had something to do with the slow progress of palæontology?
