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." [176] The vermiform appendage of the coecum 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." [177] "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." [178] 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." [179] 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?
