Virchow, 1877:[244] "Ich möchte namentlich darauf aufmerksam machen, dass diejenigen, welche den nächsten Anknüpfungspunkt für die Urbevölkerung Amerika's bei den Eskimo's suchen, welche ferner die Sprache und die Formen der Eskimo's nach Asien hinein verfolgen, leicht ein petitio principii machen dürften, insofern als es wohl sein könnte, dass sie ein späteres Phänomen für ein früheres halten. Warum sollte nicht die Einwanderung der Eskimo's von Asien erst erfolgt sein, nachdem längst andere Theile des Continents ihre Bewohner erhalten hatten?"
1878:[245] "Nun ist es sehr bemerkenswerth, dass gegenüber dieser physiognomischen Aehnlichkeit der Eskimos und der Mongolen eine absolute Differenze Zwischen ihnen in Bezug auf die Schädelkapsel existirt" (examined six living Greenland Eskimos).
1885:[246] "Verbinden wir dieses mit dem Umstande, dass die Sagen der Ungava-Eskimos stets nach Norden über die Hudson-Strasse verlegt werden, dass man im Baffin-Lande stets über die Fury- und Hecla-Strasse fort nach Süden als dem Schauplatz alter Sagen hinweist, und dass die westlichen Eskimos ebenso den Osten als das Land ihrer sagenhaften Helden und Stämme betrachten, so gewinnt die Vermuthung an Wahrscheinlichkeit, dass im Westen des Hudson-Bay-Gebietes die Heimath der weitverbreiteten Stämme zu suchen ist."
Chamberlain, 1889:[247] "In a paper read before the Institute last year (Proc. Can. Inst., 3d. ser., Vol. V., Fasc. i., October, 1887, p. 70), I advanced the view that instead of the Eskimo being derived from the Mongolians of northeastern Asia, the latter are on the contrary descended from the Eskimo, or their ancestors, who have from time immemorial inhabited the continent of America."
Boas, 1901:[248] "All these data seem to me to prove conclusively that the culture of the Alaskan Eskimo is very greatly influenced by that of the Indians of the North Pacific coast and by the Athapascan tribes of the interior. This is in accord with the observation that their physical type is not so pronounced as the eastern Eskimo type. I believe, therefore, that H. Rink's opinion of an Alaskan origin of the Eskimo is not very probable. If pure type and culture may be considered as significant, I should say that the Eskimo west and north of Hudson Bay have retained their ancient characteristics more than any others. If their original home was in Alaska, we must add the hypothesis that their dispersion began before contact with the Indians. If their home was east of the Mackenzie, the gradual dispersion and ensuing contact with other tribes would account for all the observed phenomena. * * * On the whole, the relations of North Pacific and North Asiatic cultures are such that it seems plausible to my mind that the Alaskan Eskimo are, comparatively speaking, recent intruders, and that they at one time interrupted an earlier cultural connection between the two continents."
To which he adds in the second part of this work,[249] speaking of the Eskimo taboos: "It may perhaps be venturesome to claim that the marked development of these customs suggests a time when the Eskimo tribes were inland people who went down to the sea and gradually adopted maritime pursuits, which, however, were kept entirely apart from their inland life, although in a way this seems an attractive hypothesis."
