The differentiation of the species Man into various races, with permanent traits and inhabiting definite areas, took place early in the present geologic epoch. Of these races there are four which are well-marked, each developed in one of the continental areas as they existed at the time referred to. They are the Eurafrican or white, the Austafrican or black, the Asian or yellow, and the American or red race. The color-names given them are merely approximations, and are retained for the sake of convenience, and as expressing a general and obvious characteristic.[1] The American race was that which was found occupying the whole of the New World when it first became revealed to Europeans. Its members are popularly known as “Indians,” or “American Indians,” because Columbus thought that the western islands which he discovered were part of India; and his error has been perpetuated in the usually received appellation of its inhabitants. To the ethnographer, however, they are the only “Americans,” and their race is the “American Race.” When investigation proved that the continent was not a part of Asia, but a vast independent land-area surrounded by wide oceans, the learned began to puzzle themselves with the problem of the origin of its inhabitants. The Hebrew myths of the creation of man and of a universal deluge in which the whole species perished except a few in Western Asia, for a long time controlled the direction of such speculations. The wildest as well as the most diverse hypotheses were brought forward and defended with great display of erudition. One of the most curious was that which advanced the notion that the Americans were the descendants of the ten “lost tribes of Israel.” No one, at present, would acknowledge himself a believer in this theory; but it has not proved useless, as we owe to it the publication of several most valuable works.[2] Another equally vain dream was that of “the lost Atlantis,” a great island or land-connection which was imagined to have existed within recent times between Northern Africa and South America. A reminiscence of it was supposed to have survived in a story of the Egyptian priests preserved by Plato, that beyond the Pillars of Hercules was a great island which had since sunk in the sea. The account may have referred to the Canary Islands, but certainly not to any land-bridge across the Atlantic to the American Continent. Such did exist, indeed, but far back in the Eocene period of the Tertiary, long before man appeared on the scene. The wide difference between the existing flora and fauna of Africa and South America proves that there has been no connection in the lifetime of the present species.[3]
