In the previous chapter we have seen that, on general grounds, evolution as applied to man is untenable; and that the theory of creation is more rational and less liable to objection. We may now consider how the geological and zoological conditions of man's advent on the earth accord with evolution; and I think we shall find, as might be expected, that they oppose great if not fatal difficulties to this hypothesis. One of the first and most important facts with reference to the appearance of man, is that he is a very recent animal, dating no farther back in geological time then the Post-glacial period, at the close of the Tertiary and beginning of the Modern era of geology. Further, inasmuch as the oldest known remains of man occur along with those of animals which still exist, and the majority of which are probably not of older date, there is but slender probability that any much older human remains will ever be found. Now this has a bearing on the question of the derivation of man, which, though it has not altogether escaped the attention of the evolutionists, has not met with sufficient consideration. Perhaps the oldest; known human skull is that which has been termed the "Engis" skull, from the cave of Engis, in Belgium. With reference to this skull, Professor Huxley has candidly admitted that it may have belonged to an individual of one of the existing faces of men. I have a cast of it on the same shelf with the skulls of some Algonquin Indians, from the aboriginal Hochelaga, which preceded Montreal; and any one acquainted with cranial characters would readily admit that the ancient Belgian may very well have been an American Indian; while on the other hand his head is not very dissimilar from that of some modern European races. This Belgian man is believed to have lived before the mammoth and the cave bear had passed away, yet he does not belong to an extinct species or even variety of man.
