All this proves too much for the theory. Here is the loss of useful organs and the survival of others not needed. This is not evolution, at least not the kind we have been asked to build our hopes upon for progress. Further, these so-called "relics of the brute" are counted as having no use save to support Evolution. The "gill-slits" in the neck of the human embryo are the favorite instance of this kind of fact. Haeckel and, after him others, picture the forms of fish, dog and man in embryonic state, and say in triumph, There is proof of the descent of the man from the dog and of him from the fish; and this resemblance has survived to tell the tale, there being no other use for it. But this is not the only feature that "survives." Heads and mouths and eyes also "survive." Why are these not pointed to as proofs of descent? Because we can see use for them, while there appears to be no use for the "gill-slits" except to prove Evolution. If we could see some use in the "gill-slits" in the neck of the embryo, the argument of Evolution would fall to the ground. Evolution's argument from the gill-slits and all other "relics of the brute" rests therefore on ignorance, a very unsafe foundation for a scientific theory, for knowledge is constantly increasing, especially of the human frame, and there is not the slightest doubt, reasoning from analogy and past experience, that there is use for these peculiar embryonic features. We repeat the argument of Huxley as to these rudimentary parts: "Either these rudiments are of no use, in which case they should have disappeared; or they are of use, in which case they are arguments for teleology." (_Darwinism and Design_, p. 151.) Evidences of this nature are of that kind called circumstantial, and in law are least relied upon, for on such evidence some innocent men have been hung. Shall we condemn the whole race to a bestial origin on the same evidence? All arguments founded on such facts are weak, puerile and unworthy of scientists. No wonder that Prof. Paulsen said Haeckel's speculations are "a disgrace to the philosophy of Germany." Shall we suspend a philosophy of the universe upon a few long hairs? Shall we allow the guess as to the origin of the tip of the outer ear to revolutionize theology? Shall we risk our eternal destiny on the supposed uselessness of the so-called "gill-slits" in premature puppies? Yet this is the demand of Evolution reduced to plain English. 4.
