race valueless; while, on the other hand, the fact that here we have a greater number and variety of languages than is to be found in any of the other grand divisions of the earth, is strong evidence of a diversity more radical than that which simply arises from tribal affiliations. In view of the wide differences existing between the native Americans themselves in every feature which admits of being subjected to a scientific test, we are forced to the conclusion, solely resting on the evidence in the case, that the theory of American ethnic unity is a delusion, an infatuating theory which served only to blind its advocates as to the plain facts, and led them into grave errors which will become all the more palpable as scientific investigation progresses. As yet no substantial reason for considering the ancient occupant of this continent as peculiar in himself, and as unlike the rest of mankind, has been set forth. Nothing in the American’s physical organization points to an origin different from that to which each of the species of the _genus homo_ may be assigned. Whatever truth there may be in the diverse origin of the black and white race, the separate creation theory, in so far as it maintains that the Creator originated upon the soil of this continent a peculiar and separate race of men, must in the eyes of this age of criticism lack evidence, and be assigned to its place with thousands of others which from time immemorial have been contributing to the construction of a foundation reef which will ultimately rise like a bold headland above the dark waters of uncertainty into the realm of truth.
