essentially dissimilar to those of the old world; while man in the new world, though bearing traces of high antiquity, is specifically identical with all the races of the earth. It is well known that the hybrids of plants and of animals do not possess the power of reproduction, while in the intermixture of the races of men no such sterility of progeny can be found; and therefore, as there are no human hybrids, there are no separate human races or species, but all are one family. Besides being consistent with sound reasoning, this theory can bring to its support the testimony of the sacred writings, and an internal evidence of a creation divine and spiritual, which is sanctioned by tradition, and confirmed by most philosophic minds. Man, unlike animals, is the direct offspring of the Creator, and as such he alone continues to derive his inheritance from a divine source. The Hebraic record, continue the monogenists, is the only authentic solution of the origin of all things; and its history is not only fully sustained by science, but it is upheld by the traditions of the most ancient barbarous nations, whose mythology strikingly resembles the Mosaic account of the creation, the deluge, and the distribution of peoples. The Semitic family alone were civilized from the beginning. A peculiar people, constantly upheld by special act of Providence from falling into paganism, they alone possessed a true knowledge of the mystery of creation. A universal necessity for some form of worship, a belief inherent in all mankind, in an omnipotent deity and a life beyond the grave, point to a common origin and prophesy a common destiny. This much for the monogenists. The second hypothesis, that of the polygenists, holds that there was not one only, but several independent creations, each giving birth to the essential, unchangeable peculiarities of a separate race; thus constituting a diversity of species with primeval adaptation to their geographical distribution. Morton, Agassiz, Gliddon, and others in America, stand sponsors for this theory. The physiological differences of race, they say, which separate mankind into classes, do not result from climatic surroundings, but are inherited from original progenitors. They point to marked characteristics in various peoples which have remained unchanged for a period of four thousand years. In place of controverting divine revelation, they claim that Mosaic history is the history of a single race, and not the history of all mankind; that the record itself contains an implied existence of other races; and that the distribution of the various species or races of men, according to their relative organisms, was part of the creative act, and of no less importance than was the act of creation.
