He must necessarily deduce therefrom an ordinal distinction, even on the one ground of the correlations and modifications of structure implied in the erect position. It would indeed be sufficient for this purpose to consider merely the balancing of the skull on the neck, or the structure of the foot, and the consequences fairly deducible from either of them. Nay, were such imaginary anatomist a derivationist, and ignorant of the geological date of his specimens, and as careless of the differences in respect to brain as some of his human _confrères_, he might, referring to the loss specialised condition of man's teeth and foot, conclude, not that man is an improved ape, but that the ape is a specialised and improved man. He would be obliged, however, even on this hypothesis, to admit that there must be a host of missing links. Nor would these be supplied by the study of the living races of men, because these want even specific distinctness, and differ from the apes essentially in those points on which an ordinal distinction can be fairly based. This isolated position of man throughout the whole period of his history, grows in importance the more that it is studied, and can scarcely be the result of any accident of defective preservation of intermediate forms. In the meantime, when taken in connection with, the fact previously stated, that man is equally isolated when he first appears on the stage, it deprives evolution, as applied to our species, of any precise scientific basis, whether zoological or geological. I do not attach any importance whatever, in this connection, to the likeness in type or plan between man and other mammals. Evolutionists are in the habit of taking for granted that this implies derivation, and of reasoning as if the fact that the human skeleton is constructed on the same principles as that of an ape or a dog, must have some connection with a common ancestry of these animals. This is, however, as is usual with them, begging the question. Creation, as well as evolution, admits of similarity of plan. When Stephenson constructed a locomotive, he availed himself of the principles and of many of the contrivances of previous engines; but this does not imply that he took a mine-engine, or a marine-engine, and converted it into a railroad-engine. Type or plan, whether in nature or art, may imply merely a mental evolution of ideas in the maker, not a derivation of one object from another.
