There are many advocates for an Asiatic origin, both among ancient and modern speculators. Favorable winds and currents, the short distance between islands, traditions, both Chinese and Indian, refer the peopling of America to that quarter. Similarity in color, features, religion, reckoning of time, absence of a heavy beard, and innumerable other comparisons, are drawn by enthusiastic advocates, to support a Mongolian origin. The same arguments, in whole or in part, are used to prove that America was peopled by Egyptians, by Ethiopians, by French, English, Trojans, Frisians, Scythians; and also that different parts were settled by different peoples. The test of language has been applied with equal facility and enthusiasm to Egyptian, Jew, Phoenician, Carthaginian, Spaniard, Chinese, Japanese, and in fact to nearly all the nations of the earth. A complete review of theories and opinions concerning the origin of the Indians, I propose to give in another place; not that intrinsically they are of much value, except as showing the different fancies of different men and times. Fancies, I say, for modern scholars, with the aid of all the new revelations of science, do not appear in their investigations to arrive one whit nearer an indubitable conclusion.
It was obvious to the Europeans when they first beheld the natives of America, that these were unlike the intellectual white-skinned race of Europe, the barbarous blacks of Africa, or any nation or people which they had hitherto encountered, yet were strikingly like each other. Into whatsoever part of the newly discovered lands they penetrated, they found a people seemingly one in color, physiognomy, customs, and in mental and social traits. Their vestiges of antiquity and their languages presented a coincidence which was generally observed by early travelers. Hence physical and psychological comparisons are advanced to prove ethnological resemblances among all the peoples of America, and that they meanwhile possess common peculiarities totally distinct from the nations of the old world. Morton and his confrères, the originators of the American homogeneity theory, even go so far as to claim for the American man an origin as indigenous as that of the fauna and flora. They classify all the tribes of America, excepting only the Eskimos who wandered over from Asia, as the American race, and divide it into the American family and the Toltecan family. Blumenbach classifies the Americans as a distinct species. The American Mongolidæ of Dr Latham are divided into Eskimos and American Indians. Dr Morton perceives the same characteristic lineaments in the face of the Fuegian and the Mexican, and in tribes inhabiting the Rocky Mountains, the Mississippi Valley, and Florida. The same osteological structure, swarthy color, straight hair, meagre beard, obliquely cornered eyes, prominent cheek bones, and thick lips are common to them all. Dr Latham describes his American Mongolidæ as exercising upon the world a material rather than a moral influence; giving them meanwhile a color, neither a true white nor a jet black; hair straight and black, rarely light, sometimes curly; eyes sometimes oblique; a broad, flat face and a retreating forehead. Dr Prichard considers the American race, psychologically, as neither superior nor inferior to other primitive races of the world. Bory de St Vincent classifies Americans into five species, including the Eskimos. The Mexicans he considers as cognate with the Malays. Humboldt characterizes the nations of America as one race, by their straight glossy hair, thin beard, swarthy complexion, and cranial formation. Schoolcraft makes four groups; the first extending across the northern end of the continent; the second, tribes living east of the Mississippi; the third, those between the Mississippi and the Rocky Mountains; and the fourth, those west of the Rocky Mountains. All these he subdivides into thirty-seven families; but so far as those on the Pacific Coast are concerned, he might as reasonably have made of them twice or half the number.
