Monotonous race type of small area.

If the distribution of the several races be examined in the light of this conclusion, it becomes apparent that the races who have succeeded in appropriating only limited portions of the earth's surface, though each may be a marked variant of the human family, are characterized by few inner diversities, either of physical features or culture. Their subdivisions feel only in a slight degree the differentiating effects of geographic remoteness, which in a small area operates with weakened force; and they enjoy few of those diversities of environment which stimulate variation. They form close and distinct ethnic unities also because their scant numbers restrict the appearance of variations. The habitat of the negro race in Africa south of the Sahara, relatively small, limited in its zonal location almost wholly to the Tropics, poorly diversified both in relief and contour, has produced only a retarded and monotonous social development based upon tropical agriculture or a low type of pastoral life. The still smaller, still less varied habitat of the Australian race, again tropical or sub-tropical in location, has produced over its whole extent only one grade of civilization and that the lowest, one physical, mental and moral type.[301]

Wide race distribution and inner diversities.

The Mongoloid area of distribution, on the other hand, is so large that it necessarily includes a great range of climates and variety of geographic conditions. [Maps pages 103 and 225.] Representatives of this race, reflecting their diversified habitats, show many ethnic differentiations. They reveal also every stage and phase of cultural development from the industrialism of Japan, with its artistic and literary concomitants, to the savage economy and retarded intellectual life of the Chukches fisher tribes or the Giljak hunters of Sakhalin. The white race, identified primarily with Europe, that choice and diversified continent, comprised also a large area of southwestern Asia and the northern third of Africa. It thus extended from the Arctic Circle well within the Tropics. Its area included every variety of geographic condition and originally every degree of cultural development; but the rapid expansion in recent centuries of the most advanced peoples of this race has made them the apostles of civilization to the whole world. It has also given them, through the occupation of Australia and the Americas, the widest distribution and the most varied habitats. As agents of the modern historical movement, however, they are subjected to all its assimilating effects, which tend to counteract the diversities born of geographic segregation, and to raise all branches of the white race to one superior cosmopolitan type. On the other hand, the vast international division of labor and specialization of production, geographically based and entailed by advancing economic development, besides the differences of traditions and ideals reaching far back into an historic past and rooted in the land, will serve to maintain many subtle inner differences between even the most progressive nations.

Area and language.

Hence the wide area which Darwin found to be most favorable to improved variation and rapid evolution in animals, operates to the same end in human development, and its influence becomes a law of anthropo-geography. It permeates the higher aspects of life. The wide, varied area occupied by the Germanic tribes of Europe permitted the evolution of the many dialects which finally made the richness of modern German speech. English has gained in vocabulary and idiom with every expansion of its area. New territories mean to a people new pursuits, new relations, new wants; and all these become reflected in their speech. Languages, like peoples, cease to grow with national stagnation.[302] To such stagnation movement or expansion is the surest antidote. America will in time make its contribution to the English tongue. The rich crop of slang that springs up on the frontier is not wholly to be deplored. The crudeness and vigor of cowboy speech are marks of youth: they are also promises of growth. Language can not live by dictionary alone. It tends to form new variants with every change of habitat. The French of the Canadian habitant has absorbed Indian and English words, and adapted old terms to new uses;[303] but it is otherwise a survival of seventeenth century French. Boer speech in South Africa shows the same thing—absorption of new Kaffir and English words, coupled with marks of retardation due to isolation. Religion in the same way gains by wide dispersal. Christianity is one thing in St. Petersburg, another among the Copts of Cairo, another in Rome, another in London, and yet another in Boston. Buddhism takes on a different color in Ceylon, Tibet, China and Japan. In religion as in other phases of human development, differentiation must mean eventual enrichment, a larger content of the religious idea, to which each faith makes its contribution.

Large area a guarantee of racial or national permanence.
