“The os coccyx in man, though functionless as a tail, plainly represents this part in other vertebrate animals. At an early embryonic period it is free, and, as we have seen, projects beyond the lower extremities.”[42] It sometimes happens that we find external relics of a tail. Professor Haeckel, in Fig. 195, vol. i. of The Evolution of Man (library edition), shows the tail of a six months’ old boy, which Granville Harrison removed by operation. The anthropoid ape, like man, has only the rudiment of a tail.
The ear muscles are rudimentary in man. “It is well known how readily domestic animals—horses, cows, dogs, hares, etc.—point their ears and move them in different directions. Most of the apes do the same, and our earlier ape ancestors were also able to do it. But our later simian ancestors, which we have in common with the anthropoid apes, abandoned the use of these muscles, and they gradually became rudimentary and useless. However, we possess them still. In fact, some men can still move their ears a little backward and forward by means of the drawing and withdrawing muscles; and with practice this faculty can be much improved. But no man can now lift up his ears by the raising muscle, or change the shape of them by the small inner muscles. These muscles were very useful to our ancestors, but are of no consequence to us. This applies to most of the anthropoid apes as well.”[43]
The vermiform appendage of the cœcum is not only practically useless, but the source of that extremely dangerous complaint, appendicitis. It is remarkable that this organ is practically identical with the vermiform appendage of anthropoid apes, yet none of the other monkeys present any such resemblance with men. Professor Haeckel, speaking of the vermiform appendage, says: “The only significance of it in man is that not infrequently a cherry-stone or some other hard and indigestible matter penetrates into its narrow cavity, and by setting up inflammation and suppuration causes the death of otherwise sound men. Teleology has great difficulty in giving a rational explanation of, and attributing to a beneficent Providence, this dreaded appendicitis. In our plant-eating ancestors this rudimentary organ was much larger, and had a useful function.”[44]
“In order to understand the existence of rudimentary organs, we have only to suppose that a former progenitor possessed the parts in question in a perfect state, and that under changed habits of life they became greatly reduced, either from simple disuse or through the natural selection of those individuals which were least encumbered with a superfluous part, aided by the other means previously indicated.”[45]
Whatever the precise explanation may be, can we bring ourselves to suppose that God created us with a number of useless organs, or that He placed them there as a snare to entrap our judgment? Again, “rudimentary organs, for the most part, display a congenital lack of the power of resistance, and, as Darwin suggested, for this reason they are frequently the seats of disease.”[46] Can anyone imagine his Maker arranging all this on purpose? I can not. We are assured by pious apologists that God has instituted pain in order to save us from injuring ourselves; how can He, then, have specially provided us with organs whose only function is to be a source of danger?
Many other examples might be given bearing on this line of argument; but enough has been said, I hope, to convince the reader that in these rudimentary organs there is overpowering evidence against separate acts of creation, and in favour of an animal origin of the human race. Besides this, we have also the evidence derived from the study of our bodily structure and embryonic development. The bearing of these three great classes of fact is, as Charles Darwin remarks, unmistakeable. “It is only our natural prejudice, and that arrogance which made our own forefathers declare that they were descended from demi-gods, which lead us to demur to this conclusion.”[47]
§ 5. The Overthrow of the Doctrines of the Fall and Original Sin.
THE IMPORTANCE OF THE QUESTION.
No Biblical standpoint is more directly opposed to modern evolutionary views than the doctrine of the Fall and Atonement. We have seen, in the chapters on the Higher Criticism and on Comparative Mythology, that the Bible story of Creation is nothing but a borrowed legend; and we have now seen that it could not in any case be true. If it were, Evolution would be untrue. Now, the account of the fall of man is an exceedingly important portion of the Bible, the whole fabric of the Christian faith being constructed upon it; and there is no doubt whatever that the average Christian realises this, and continues to believe in the “Fall.” He may accept the doctrine of the evolution of the physical nature of man; but he flatly denies that his intellect and moral attributes were a part of the process, although such authorities as Darwin, Huxley, and Romanes clearly point out that man’s intellect and moral sense have arisen from lower stages of the same faculties in his primate ancestors.
