On this subject, as upon all others pertaining to American antiquities and peoples, writers are divided; yet it is not difficult to marshal in support of race unity for native Americans the very highest authority; and what is of most importance is the facts are beyond question behind their theory. Citing the facts on which certain authors rely to establish the unity of the American race, Bancroft says: 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. * * * * * * Morton and his confreres, 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 Esquimaux who wandered over from Asia, as the American race, and divided it into the American family and the Toltecan family. Blumenbach classifies the Americans as a distinct species. The American Mongolidae of Dr. Latham are divided into Esquimaux and American Indians. Dr. Morton perceives the same characteristic lineaments on 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. * * * * * * Humboldt characterizes the nations of America as one race, by their straight glossy hair, thin beard, swarthy complexion and cranial formation.
