All anthropological research on the Eskimo has naturally one ultimate object, which is the clearing up of the problems of the origin and antiquity of this highly interesting human strain; and it may well be asked what further light on these problems has been shed by the studies here dealt with. To show this with a proper perspective it will be requisite to briefly review the previous ideas on these problems. Origin of the Name "Eskimo"According to Charlevoix (Nouv. France, III, 178), the term "Eskimo" is a corruption of the Abenaki Indian Esquimantsic or the Ojibway Ashkimeg, both terms meaning "those who eat raw flesh." In the words of Captain Hooper, For Brinton, The Eskimo call themselves "Innuit," said to be the plural of in-nu, the man, hence "the people"; the same being as a rule the meaning of the name by which the various tribes of the Indian call themselves. On the Asiatic coast the Eskimo is known as the "Yuit," "Onkilon," "Chouklouks," or "Namollo"; while in the east appears the name "Karalit." None of this has thrown any light on the origin of the Eskimo. FOOTNOTES:Opinions By Former and Living StudentsOrigin in Asia.—Many opinions on the origin of the Eskimo have been expressed by different authors. Among the earliest of these were those of missionaries, such as Crantz (1779), and of the early explorers, such as Steller, v. Wrangell, LÜtke and others. They were based on the general aspect of the Eskimo, particularly that of his physiognomy; and seeing that in many features he resembled most the mongoloid peoples of Asia they attached him to these, which meant the conclusion that he was of Asiatic derivation. Quite soon, however, there began to appear also the opinions of students of man. The first of these was that of Blumenbach, as expressed in his Inaugural Thesis of 1781. In this thesis, more particularly its second edition, he classifies the Eskimo expressly as a part of the Caucasian or white race. But after obtaining an Eskimo skull and an Eskimo body he changes his opinion and in 1795-1806 he comes out with a definite classification of the Eskimo as a member of the Mongolians; and a similar conclusion, with its implied or expressed consequence of a migration from Asia to America, has been reached since, mainly on somatological but also in part on linguistic and cultural bases, by a large number of authors, including Lawrence, Morton, Pickering, Latham, Flower, Peschel, Topinard, Brinton, Virchow (1877), Quatrefages and Hamy (1882), Thalbitzer, Bogoras and numerous others. With all of this, the conception of the Asiatic origin of the Eskimo has not passed the status of a strong probability, lacking a final conclusive demonstration. A chronological list of the more noteworthy individual statements is given at the end of this section. Origin in America.—Since the earlier parts of the nineteenth century the opinion began to be expressed that the Eskimo is not of Asiatic but of American origin. Already in 1847 Prichard tells us that there are those who "consider them as belonging to the American family," and he plainly favors this conception. Between 1873 and 1890 the American origin of the Eskimo is repeatedly asserted by Rink, who for 16 winters and 22 summers lived with the eastern Eskimo, first as a scientific explorer and later as royal inspector or governor of the southern Danish settlements in Greenland (preface by R. Brown to Rink's Tales and Traditions, 1875). In this opinion, briefly, the Eskimo were derived from the inland Indian tribes of Alaska; without referring to the origin of the Indian. Rink's authoritative opinion was followed or paralleled by Daniel Wilson (1876), Grote, Krause, Ray, Keane, Brown, and others. In 1887 Chamberlain expresses the somewhat startling additional theory that it was not the Eskimo who was derived from the Mongolians but the Mongolians from the Eskimo or their American ancestors. And in 1901-1910 Boas comes to the conclusion that the Eskimo probably originated from the inland tribes (Indian?) in the Hudson Bay region. An interesting case in these connections is that of Rudolf Virchow. In 1877 (see details at the end of this section) he expresses the belief in the Eskimo coming from Asia; in 1878 he seems to be uncertain; and in 1885 he comes out in support of the opinion that the original home of the Eskimo may have been in the western part of the Hudson Bay region. Among later students of the problem, Steensby Wissler, not explicit as to the Eskimo in 1917 (The American Indian), in 1918 (ArchÆology of the Polar Eskimo) finds, after Steensby, the most acceptable theory of the Eskimo origin to be that "they expanded from a parent group in the Arctic Archipelago"; but in 1922, in the second edition of his The American Indian, he repeats word for word his opinion of 1917, which appears to favor an Asiatic derivation. Origin in Europe—Identity with Upper Palaeolithic man.—About the sixties of last century growing discoveries in France of implements, etc., of later palaeolithic man brought about a realization that not a few of these implements and other objects, particularly those of the Magdalenian period, resembled like implements and objects of the Eskimo; from which, together with the considerations of the similarities of fauna (reindeer, musk-ox, etc.), and of climate, there was but a step to a more or less definite identification of the Magdalenians and Solutreans with the Eskimo. In 1870 Pruner-Bey However, there were also many who opposed the effort at a direct connection of the upper palaeolithic man of Europe and the Eskimo. Among these were Geikie, Flower, Rae, Daniel Wilson, Robert Brown, DÉchelette, Laloy. At present the theory is supported mainly by Morin and Sollas, opposed by Steensby, Burkitt, Keith, MacCurdy, and others; while most students of the Eskimo ignore the question. Other hypotheses.—Besides the preceding ideas which attribute the origin of the Eskimo to Asia, or America, or old Europe, there were also others that failed to receive a wider support; and there were authors and students who remained undecided or were too cautious to definitely formulate their beliefs. Some of the former as well as the latter deserve brief mention. Gallatin, in 1836, mainly on linguistic grounds, recognizes the fundamental relation of the Eskimo and the Indian and seems inclined to the American origin of the former, but makes no clear statement to that effect. For Meigs (1857), who probably followed an earlier opinion, the Eskimo came "from the islands of the Polar Sea." C. C. Abbott (1876) saw Eskimo in the early inhabitants of the Delaware Valley. To Grote (1875, 1877), the Eskimo were "the existing representatives of the man of the American glacial epoch"; they were modified Pliocene men. NordenskiÖld (1885) follows closely Meigs and Grote; the Eskimo may be "the true autochthones of the Polar regions," having inhabited them from before the glacial age, during more genial climate. Keane (1886) believed the Eskimo developed from the Aleuts. For De Quatrefages (1887), man originated in the Tertiary in northern Asia, spread from there, and some of his contingents may have reached America and been the ancestors of the Eskimo; the western tribes of the latter being a mixture of the Eskimo with Asiatic brachycephals. Nansen (1893) avoids a discussion of the origin of the Eskimo; and the same caution is observable more or less in most modern writers. The following chart of the more noteworthy opinions regarding the origin of the Eskimo will show at a glance the diversity of the views and their lack of conclusiveness. FOOTNOTES:Theories as to the Origin of the Eskimo
ASIATICSSteller, 1743: Cranz, 1779: Blumenbach, 1781: But in his "BeitrÄge zur Naturgeschichte," 2d ed., GÖttingen, 1806, Blumenbach classes both the Lapps and the Eskimo with the Mongolians (Anthr. Treatises of Blumenbach, Lond., 1865, p. 304): "The remaining Asiatics, except the Malays, with the Lapps in Europe, and the Esquimaux in the north of America, from Bering Strait to Labrador and Greenland. They are for the most part of a wheaten yellow, with scanty, straight, black hair, and have flat faces with laterally projecting cheek bones, and narrowly slit eyelids." Von Wrangell, 1839: Lawrence, 1822: "The Eskimaux are formed on the Mongolian model, although they inhabit countries so different from the abodes of the original tribes of central Asia." Latham, 1850: 1851: Pickering, 1854: Wilson, 1863: Markham, 1856: Whymper, 1869: Peschel, 1876: "It is not likely that the Eskimo spread from America to Asia, because of all Americans they have preserved the greatest resemblance in racial characters to the Mongolian nations of the Old Kuhl, 1876: Dall, 1877: "The northern route was clearly by way of Bering Strait; *** Linguistically, no ultimate distinction can be drawn between the American Innuit and the American Indian. *** I shall assume, what is also assumed by Mr. Markham, that the original progenitors of the Innuit were in a very primitive, low, and barbarous condition. *** "I assume, then, that the larger part of North America may have been peopled by way of Bering Strait. *** I believe that this "My own impression agrees with that of Doctor Rink that the Innuit were once inhabitants of the interior of America; that they were forced to the west and north by the pressure of tribes of Indians from the south; that they spread into the Aleutian region and northwest coast generally, and possibly simultaneously to the north; that their journeying was originally tentative, and that they finally settled in those regions which afforded them subsistence, perhaps after passing through the greater portion of Arctic America, leaving their traces as they went in many places unfit for permanent settlement; that after the more inviting regions were occupied, the pressure from Indians and still unsatisfied tribes of their own stock, induced still further emigration, and finally peopled Greenland and the shores of northeastern Siberia; but that these latter movements were, on the whole, much more modern, and more local than the original exodus, and took place after the race characteristics and language were tolerably well matured. *** "I conclude that at present the Asiatic Innuit range from Koliuchin Bay to the eastward and south to Anadyr Gulf. *** "To the reflux of the great wave of emigration, which no doubt took place at a very early period, we may owe the numerous deserted huts reported by all explorers on the north coasts of Asia, as far east as the mouth of the Indigirka. At one time, I thought the migration to Asia had taken place within a few centuries, but subsequent study and reflection has convinced me that this could not have been the case. No doubt successive parties crossed at different times, and some of these may have been comparatively modern." Rae, 1878: "That these people (the Eskimos) have been driven from their own country in the northern parts of Asia by some unknown pressure of circumstances, and obliged to extend themselves along the whole northern coast line of America and Greenland, appears to be likely, and that the route followed after crossing Bering Strait was of necessity along the coast eastward, being hemmed in by hostile Indians on the south, and driven forward by pressure from the west ***. "Such were my opinions 12 years ago, and their correctness has been rather confirmed than otherwise, by all that we have since learned. ***" 1887: "Doctor Rae also thinks that the Eskimos came from across Bering Strait from Asia. Their traditions and many other things point in that direction, and they are in no way related to the ancient cave men of Europe." Dawson, 1880: Quatrefages et Hamy; 1882: Brown, 1888: Ratzel, 1897: "Ethnographic indications also point predominantly to the west. *** "But we have an equal right to suppose a migration from America into Asia." Thalbitzer, 1914: FÜrst and Hansen, 1915: Mathiassen, 1927: Jochelson, 1928: FOOTNOTES:AMERICANPrichard, 1847: Rink, 1890: Rink, 1873: "The author explains some of the most common traditions from Greenland as simply mythical narrations of events occurring in the far northwest corner of America, thereby pointing to the great probability of that district having been the original home of the nation, in which they first assumed the peculiarities of their present culture." Captain Pim also expressed his belief that "the Eskimo were pure American aborigines, and not of Asiatic descent." Rink, 1875: "The probable identity of the 'inlanders' with the Indians has already been remarked on. When the new coast people began to spread along the Arctic shores, some bands of them may very probably have crossed Bering Strait and settled on the opposite shore, which is perhaps identical with the fabulous country of Akilinek. On the other hand, there is very little probability that a people can have moved from interior Asia to settle on its polar seashore, at the same time turning Eskimo, and afterwards almost wholly emigrated to America. "On comparing the Eskimo with the neighboring nations, their physical complexion certainly seems to point at an Asiatic origin; but, as far as we know, the latest investigations have also shown a transitional link to exist between the Eskimo and the other American nations, which would sufficiently indicate the possibility of a common origin from the same continent." Rink, 1875: "When we consider the existing intercourse between the inhabitants on both sides of Bering Strait, we find many circumstances to justify the conclusion that those traditions of the Greenland Eskimo refer to the origin of the Eskimo sledge dog from the training of the Arctic wolf, to the first journeys upon the frozen sea, and to intercourse between the aboriginal Eskimo and the Asiatic coast." Rink, 1886: Wilson, 1876: "In this direction, then, a North American germ of population may have entered the continent from Asia, diffused itself over the Northwest, and ultimately reached the valleys of the Mississippi, and penetrated to southern latitudes by a route to the east of the Rocky Mountains. Many centuries may have intervened between the first "With Asiatic Esquimaux thus distributed along the coast adjacent to the dividing sea; and the islands of the whole Aleutian group in the occupation of the same remarkable stock common to both hemispheres: The only clearly recognizable indications are those of a current of migration setting toward the continent of Asia, the full influence of which may prove to have been more comprehensive than has hitherto been imagined possible. ***" Grote, 1877: Krause, 1883: Ray, 1885: "That they have followed the receding line of ice, which at one time capped the northern part of this continent, along the easiest lines of travel is shown in the general distribution of a similar people, speaking a similar tongue, from Greenland to Bering Strait; in so doing they followed the easiest natural lines of travel along the watercourses and the seashore, and the distribution of the race to-day marks the routes traveled. The seashore led them along the Labrador and Greenland coasts; Hudson Bay and its tributary waters carried its quota towards Boothia Land; helped by Back's Keane, 1886: No individual or decided standpoint on the question is taken in the author's Man, Past and Present, 1920 edition. Brown, 1881: "It is also clear that this migration has always been from west to east, as also has been that of the Indian tribes; *** "Did these hyperboreans come from Asia or are they evolutions, differentiations, as it were, of some of the other American races? "Doctor Rink seems not far from the truth when he indicates the rivers of Central Arctic America as the region from whence the Eskimo spread northward. *** "It is not at all improbable that the original progenitors of the race may have been a few isolated families, members of some small Indian tribe, or the decaying remnants of a larger one. Little by little they were expelled from their hunting and fishing grounds on the original river bank until, finding no place amid the stronger tribes, they settled in a region where they were left to themselves. *** "It may, however, be taken as proved that the Eskimo are in no respect and never were a European people; that they are not and never were an Asiatic one, except to the small extent already described; that the handful of people settled on the Siberian shore migrated from America, and that it is very probable the Eskimo came from the interior of Arctic America, Alaska more likely than from any other part of the world." Virchow, 1877: 1878: 1885: Chamberlain, 1889: Boas, 1901: To which he adds in the second part of this work, Boas, 1910: Clark Wissler, 1917. Pages 361-362: "Our review of New World somatic characters revealed the essential unity of the Indian population. It is also clear that there are affinities with the Mongoloid peoples of Asia. Hence, we are justified in assuming a common ancestral group for the whole Mongoloid-Red stream of humanity. We have already outlined the reasons for assuming the pristine home of this group to be in Asia." Page 335: "For example, the Eskimos, whose first appearance in the New World must have been in Alaska, spread only along the Arctic coast belt to its ultimate limits." 1918 1922. EUROPEANDawkins, 1866: "The only inference that can be drawn from these premises is that the people in question were decidedly Esquimaux, related to them precisely in the same way as the reindeer and musk sheep of those days were to those now living in the high North American latitudes. The sole point of difference is the possession of the dog by the latter people, but in the vast lapse of time between the date of their sojourn in Europe and the present day the dog might very well have been adopted from some other superior race, or even reduced under the rule of man from some wild progenitor. By this discovery a new people is added to those which formerly dwelt in Europe. The severity of the climate in southern Gaul is proved by the northern animals above mentioned. As it became warmer musk sheep, reindeer, and Esquimaux would retreat farther and farther north until they found a resting place on the American shore of the great Arctic Sea. Possibly in the case of the Esquimaux the immigration of other and better-armed tribes might be a means of accelerating this movement." Hamy, 1870: Dawkins, 1874 1880: "All these points of connection between the cave men and the Eskimos can, in my opinion, be explained only on the hypothesis that they belong to the same race ***." The cave man: "From the evidence brought forward in this chapter, there is reason to believe that he is represented at the present time by the Eskimos." Mortillet, 1889: "Comme on le voit, il y a la plus grande ressemblance, tant sous le rapport physique et moral que sous le rapport artistique et industriel entre les hommes de la Madeleine et les GroËnlandais. Cette ressemblance est telle que nous pouvons en conclure que les seconds sont les descendants des premiers." Testut, 1889: "La dÉcouverte de Chancelade, en mettant en lumiÈre une analogie frappante entre le squelette de notre troglodyte pÉrigourdin et celui des Esquimaux actuels, apporte À cette opinion aussi sÉduisante que naturelle, l'appui de l'anthropologie anatomique qui, dans l'espÈce, a une importance capitale. Elle lui est de tous points favorable et ÉlÈve À la hauteur d'une vÉritÉ probable, je n'ose dire d'une vÉritÉ dÉmontrÉe, ce qui n'Était encore qu'une simple hypothÈse." HervÉ, 1893: Boule, 1913: Sollas, 1924: 1927: "Our only reason for any feeling of surprise is, not that Chancelade man should prove a close relation of the Eskimo, but that so far he is the only fossil example of his kind of which we have any certain knowledge." FOOTNOTES:OPPOSED TO EUROPEANRae, 1887: Laloy, 1898: DÉchelette, 1908: Burkitt, 1921: MacCurdy, 1924: Keith, 1925: FOOTNOTES:MISCELLANEOUS AND INDEFINITEGallatin, 1836: "There does not seem to be any solid foundation for the opinion of those who would ascribe to the Eskimaux an origin different from that of the other Indians of North America. The color and features are essentially the same; and the differences which may exist, particularly that in stature, may be easily accounted for by the rigor of the climate and partly, perhaps, by the nature of their food. The entire similarity of the structure and grammatical forms of their language with those of various Indian tribes, however different in their vocabularies, which will hereafter be adverted to, affords an almost conclusive proof of their belonging to the same family of mankind." Richardson, 1852: Meigs, 1857: Abbott, 1876: Grote, 1875: In a later communication "During the process, then, which resulted in the race modification of the Eskimos, their original numbers must have been decreased by the slowly but ever increasing cold of the northern regions, until experience and physical adaptation combined brought them to a state of comparative stability as a race." Baron NordenskiÖld Keane, 1886: Quatrefages, 1887: "Evidemment la race esquimale est amÉricaine. Au GroËnland, au Labrador, dont personne ne lui a disputÉ les solitudes glacÉes, elle a conservÉ sa puretÉ. Elle est encore restÉe pure quand elle a rencontrÉ les Peaux-Rouges proprement dits, parce que ceux-ci lui ont fait une guerre d'extermination qui ne respectait ni les femmes ni les enfants. Mais, dans le nord-ouest amÉricain, elle s'est trouvÉe en rapport avec des populations d'un caractÈre plus doux et des croisements ont eu lieu. Or, parmi ces populations, il s'en trouve de brachycÉphales. Tels sont en particulier certaines tribus, confondues À tort sous un mÊme nom avec les vrais Koluches.... Ces tribus sont de race jaune et leur crÂne ressemble si bien À celui des Toungouses que M. Hamy les a rattachÉes directement À cette famille mongole. Les Esquimaux se sont croisÉs avec elles; et ainsi ont pris naissance ces tribus, dont l'origine mÉtisse est attestÉe par le mÉlange ou la fusion des caractÈres linguistiques aussi bien qu'anatomiques." Nansen, 1893: "The likeness between all the different tribes of Eskimos, as well as their secluded position with respect to other peoples, and the perfection of their implements, might be taken to indicate that they are of a very old race, in which everything has stiffened into definite forms, which can now be but slowly altered. Other indications, however, seem to conflict with such a hypothesis, and render it more probable that the race was originally a small one, which did not until a comparatively late period develop to the point at which we now find it, and spread over the countries which it at present inhabits." Tarenetzky, 1900: De Nadaillac Jenness, 1928: FOOTNOTES:DISCUSSION AND CONCLUSIONS INDICATED BY PRESENT DATAThe maze of thoughts on the origin of the Eskimo shows one fact conclusively, which is that the necessary evidence on the subject has hitherto been insufficient. From whatever side the problem has been approached, whether linguistically, culturally, from the study of myths, or even somatologically, the materials were, it is plain, more or less inadequate and there was not enough for satisfactory comparisons. The best contributions to Eskimo studies, from the oldest to the most recent, all accentuate the need for further research, and more ample collections. Another point is that heterogeneous and wide apart as many of the opinions may seem, yet when the subject is looked upon with a larger perspective they may often perhaps be harmonized. Thus a belief in an American origin of the Eskimo need not exclude that in the Asiatic derivation of his parental stock. Even in the case of the supposed European derivation the Eskimo are understood to have reached America through Asia; there is not one suggestion of any importance advocating the coming of the Eskimo over northwestern Europe and Iceland. Only the Meigs-Grote-NordenskiÖld theory of an ancient polar race and its descent southward appears now as beyond the bounds of what would be at least partly justifiable. What is the contribution to the subject of the studies reported in this treatise, with its relatively great amount of somatological material? The answer is not easy. Even the truly great and precious material at hand is not sufficient. There are important parts of the Arctic, such as the Hudson Bay region, Baffin Land, and the central region; several parts of the west coast, such as the inland waters of the Seward Peninsula and the Eskimo portions of the Selawik, Kobuk, Noatak, and Yukon Rivers; and above all the Eskimo part of northeastern Siberia, from which there are insufficient or no collections. There is, moreover, especially in this country, a great want of skeletal material from the non-Eskimo Siberian tribes, and also from the old European peoples that are of most importance for comparisons. It must be plain, therefore, that even at present no final deductions are possible. All that can be claimed for the evidence here brought forth is that it clears, or tends to settle, certain secondary problems, and that it presents indications of value for the rest of the question. The secondary problems that may herewith be regarded as settled are as follows: 1. Unity or plurality of the race.—The materials at hand give no substantiation to the possibility of the Eskimo belonging to more than one basic strain of people. They range in color from tan or light reddish-yellow to medium brown; in stature from decidedly short to above the general human medium; in head from brachycephalic and low to extremely dolichocephalic, high and keel shaped; in eyes from horizontal to decidedly mongoloid; in orbits from microseme to hypermegaseme; in nose from fully mesorrhinic to extremely leptorrhinic; in physiognomy from pure "Indian" to extreme "Eskimo." Yet all through there runs, both in the living and in the skeletal remains, so much of a basic identity that no separation into any distinct original "races" is possible. At most it is permissible to speak of a few prevalent types. 2. Relation.—The general basic prototype of the Eskimo, according to all evidence, is so closely akin to that of the Indian that the two The next unavoidable deduction is that the mother stock of both the Eskimo and the Indian can only be identified with the great yellow-brown stem of man, the home of which was in Asia, but the roots of which, as has been discussed elsewhere, were probably in ancient (later paleolithic) Europe. 3. Mixture.—It has been assumed by Boas and others that the eastern Eskimo have become admixed with the eastern Indian and the western with the Alaskan Indian, that the physical and especially craniological differences between the eastern and western Eskimo were due to such a mixture, and that both extremes deviated from the type of the pure Eskimo, who was to be found somewhere in the central Arctic. The evidence of the present studies does not sustain such an assumption. As shown before Individual skulls and skeletons in the west, particularly in certain spots (especially on Seward Peninsula), show the same characteristics as the most diverging skulls or skeletons in the farthest northeast. And both in the west and in the east the most pronounced Eskimo characteristics exceed similar features in the Indian, indicating independent development. Such characteristics involve the stature It is well known that more or less blood mixture takes place among all neighboring peoples where contact is possible, even if otherwise there be much enmity. Such enmity, often in an extreme form, existed everywhere it seems between the Eskimo and the Indian, as a result of the encroaching of the former on the latter; there are many statements to that effect. Within historic times also there are no records of any adoptions or intermarriages between the two peoples. Nevertheless where contact took place, as on the rivers and in the southwest as well as the southeast of the Eskimo territory, some blood mixture, it would seem, must have developed. The Indian neighbors show it, and it would be strange if it remained one-sided. But of a mixture extensive enough to have materially modified the type of the Eskimo in whole large regions, such as the entire Bering Sea and most of the far northeast, there is no evidence and little not only probability but even possibility. Nothing approaching such an extensive mixture is shown by the near-by Indians; and it would be most exceptional in people of this nature if a much greater proportion of the mixture was into the Eskimo. Finally, a mixture of diverse human types, unless very old, may be expected to leave numerous physical signs of heterogeneity and disturbance, none of which is shown by either the western or eastern Eskimo. Such groups as that of the St. Lawrence Island, or that of Greenland, are among the most homogeneous human groups known. The range of variation of their characters is as a rule a strictly normal range, giving a uniform curve of distribution, which is not consistent with the notion of any relatively recent material mixture. 4. The indications.—The indications of the data and observations presented in this volume may be outlined as follows: The Eskimo throughout their territory are but one and the same broad strain of people. This strain is fundamentally related to that (or those) of the American Indian. It is also uncontestably related to the yellow-brown strains of Asia. In many respects, such as pigmentation, build of the body, physiognomy, large brain, fullness of forehead, fullness of the fronto-sphenotemporal region, largeness of face and lower jaw, height of the nose, They strongly suggest a moderate stream of people, rooted in Asia, of fairly broad and but moderately high head, of a good medium stature, with a mesorrhinic nose (and hence probably originally not far northern), and with many other characteristics in common, reaching America from northeasternmost Asia after the related Indians, spreading along the seacoasts as far as it could, not of choice, or choice alone, but mainly because of the blocking by the Indian of the roads toward the south and through the interior; and gradually modifying physically in adaptation to the new conditions and necessities; to climate, newer modes of life, the demands of the kayak, and above all to the results of the increased demands on the masticatory organs. The narrowness, increased length and increased height of the Eskimo skull, without change in its size or other characteristics, may readily be understood as compensatory adaptations, the development of which was initiated and furthered by the development and mechanical effects of the muscles of mastication. A similar conclusion has been reached in my former study on the central and Smith Sound Eskimo (1910). It has been approached or reached independently by other students of the Eskimo, notably FÜrst and Hansen (1915) in their great work on the East Greenlanders. It is a conclusion of much biological importance for it involves not merely the development but also the eventual inheritance of new characters. Former authors, it was seen, have advanced the theories of an American origin of the Eskimo. This could only mean that he developed from the American Indian. And such a development would imply physical and hereditary changes at least as great as those indicated in the preceding paragraphs, and in less time. A differentiation commenced well back in Asia, geographically and chronologically, and advancing, to its present limits, in America would seem the more probable. An origin of the Eskimo in Europe, during the last glacial invasion, would not only push into the hazy far past the same changes as here dealt with, but it would at the same time fail to explain the physical differences within the Eskimo group, and deny any substantial changes in him during the long time of his migration toward the American northern coasts. Figure 29.—Probable movements of people from northeastern Asia to Alaska and in Alaska. (A. Hrdlicka) Absolute proofs of the origin of the Eskimo, as of that of the various strains of the Indians, are hardly to be expected. Such origins are so gradual and insidious that they would escape detection even if watched for while occurring; they are noticed only after sufficient differences have developed and become established, which takes generations. The solving of racial origins must depend on sound scientific induction. Such induction may not yet be fully possible in the case of the Eskimo. The evidence is not yet complete. But with the present and other most recent data there is enough on hand for substantial indications. The evidence shows that barring some irregularities, due possibly to later intrusions or refluxes, the farther east in the Eskimo territory the observer proceeds the more highly differentiated and divergent the Eskimo becomes, and there is a greater gap The facts point, therefore, to an original identity of the source from which were derived the Indian, more particularly his latest branches, and the Eskimo, and to the identification of this source with the palaeo-Asiatic yellow-brown people of lower northern Asia. The differentiation of the Eskimo from this source must have proceeded over a fairly long time, and probably started already it would seem on the northern coasts of Asia, where conditions were present capable of beginning to shape him into an Eskimo; to be carried on since in the Bering Sea area and especially in the Seward Peninsula and farther northward and eastward. In a larger sense the cradle of the Eskimo, therefore, while starting probably in northeast Asia, covered in reality a much vaster region, extending from northern Asia and the Bering Sea to the far American Arctic.
