Man must have lived during the time in which the last representatives of the ancient animal creation—the mammoth, the great bear, the cave-hyæna, the Rhinoceros tichorinus, &c.—were still in existence. It is this earliest period of man's history which we are now about to enter upon.

We have no knowledge of a precise nature with regard to man at the period of his first appearance on the globe. How did he appear upon the earth, and in what spot can we mark out the earliest traces of him? Did he first come into being in that part of the world which we now call Europe, or is it the fact that he made his way to this quarter of our hemisphere, having first seen the light on the great plateaux of Central Asia?

This latter opinion is the one generally accepted. In the work which will follow the present volume we shall see, when speaking of the various races of man, that the majority of naturalists admit nowadays one common centre of creation for all mankind. Man, no doubt, first came into being on the great plateaux of Central Asia, and thence was distributed over all the various habitable portions of our globe. The action of climate and the influences of the locality which he inhabited have, therefore, determined the formation of the different races—white, black, yellow, and red—which now exist with all their infinite subdivisions.

But there is another question which arises, to which it is necessary to give an immediate answer, for it has been and is incessantly agitated with a degree of vehemence which may be explained by the nature of the discussion being of so profoundly personal a character as regards all of us: Was man created by God complete in all parts, and is the human type independent of the type of the animals which existed before him? Or, on the contrary, are we compelled to admit that man, by insensible transformations, and gradual improvements and developments, is derived from some other animal species, and particularly that of the ape?

This latter opinion was maintained at the commencement of the present century by the French naturalist, de Lamarck, who laid down his views very plainly in his work entitled 'Philosophie Zoologique.' The same theory has again been taken up in our own time, and has been developed, with no small supply of facts on which it might appear to be based, by a number of scientific men, among whom we may mention Professor Carl Vogt in Switzerland, and Professor Huxley in England.

We strongly repudiate any doctrine of this kind. In endeavouring to establish the fact that man is nothing more than a developed and improved ape, an orang-outang or a gorilla, somewhat elevated in dignity, the arguments are confined to an appeal to anatomical considerations. The skull of the ape is compared with that of primitive man, and certain characteristics of analogy, more or less real, being found to exist between the two bony cases, the conclusion has been arrived at that there has been a gradual blending between the type of the ape and that of man.

We may observe, in the first place, that these analogies have been very much exaggerated, and that they fail to stand their ground in the face of a thorough examination of the facts. Only look at the skulls which have been found in the tombs belonging to the stone age, the so-called Borreby skull for instance—examine the human jaw-bone from Moulin-Quignon, the Meilen skull, &c., and you will be surprised to see that they differ very little in appearance from the skulls of existing man. One would really imagine, from what is said by the partisans of Lamarck's theory, that primitive man possessed the projecting jaw of the ape, or at least that of the negro. We are astonished, therefore, when we ascertain that, on the contrary, the skull of the man of the stone age is almost entirely similar in appearance to those of the existing Caucasian species. Special study is, indeed, required in order to distinguish one from the other.

If we place side by side the skull of a man belonging to the Stone Age, and the skulls of the principal apes of large size, these dissimilarities cannot fail to be obvious. No other elements of comparison, beyond merely looking at them, seem to be requisite to enable us to refute the doctrine of this debased origin of mankind.

The figure annexed represents the skull of a man belonging to the stone age, found in Denmark; to this skull, which is known by the name of the Borreby skull, we shall have to allude again in the course of the present work; fig. 3 represents the skull of a gorilla; fig. 4 that of an orang-outang; fig. 5 that of the Cynocephalus ape; fig. 6 that of the Macacus. Place the representation of the skull found in Denmark in juxtaposition with these ill-favoured animal masks, and then let the reader draw his own inference, without pre-occupying his mind with the allegations of certain anatomists imbued with contrary ideas.
