The last point that I think necessary to bring forward here, is the information which geology gives as to the locality of the introduction of man. There can be no hesitation in affirming that to the temperate regions of the old continent belongs the honour of being the cradle of humanity. In these regions are the oldest historical monuments of our race; here geology finds the most ancient remains of human beings; here also seems to be the birthplace of the fauna and flora most useful and congenial to man; and here he attains to his highest pitch of mental and physical development. This, it is true, by no means accords with the methods of the derivationists. On their theory we should search for the origin of man rather in those regions where he is most depauperated and degraded, and where his struggles for existence are most severe. But it is surely absurd to affirm of any species of animal or plant that it must have originated at the limits of its range, where it can scarcely exist at all. On the contrary, common sense as well as science requires us to believe that species must have originated in those central parts of their distribution where they enjoy the most favourable circumstances, and must have extended themselves thence as far as external conditions would permit. One of the most wretched varieties of the human race, and as near as any to the brutes, is that which inhabits Tierra del Fuego, a country which scarcely affords any of the means for the comfortable sustenance of man. Would it not be absolutely impossible that man should have originated in such a country? Is it not certain, en the contrary, that the Fuegian is merely a degraded variety of the aboriginal American race? Precisely the same argument applies to the Austral negro and the Hottentot. They are all naturally the most aberrant varieties of man, as being at the extreme range of his possible extension, and placed in conditions unfavourable, either because of unsuitable climatal or organic associations. It is true that the regions most favourable to the anthropoid apes, and in which they may be presumed to have originated, are by no means the most favourable to man; but this only makes it the less likely that man could have been derived from such a parentage. While, therefore, the geological date of the appearance of man, the want of any link of connection between him and any preceding animal, and his dissimilar bodily and mental constitution from any creatures contemporary with him, render his derivation from apes or other inferior animals in the highest degree improbable, the locality of his probable origin confirms this conclusion in the strongest manner. It also shows that man and the higher apes are not likely to have originated in the same regions, or under the same conditions, and that the conditions of human origin are rather the coincidence of suitable climatal and organic surroundings then the occurrence of animals closely related in structure to man.
