Boyd Dawkins and Brinton, that the French cave man came hither by way of Iceland; or with Keane, that two subvarieties, the long-headed Eskimo-Botocudo type and the Mexican roundheaded type, prior to all cultural developments, reached the New World, one by Iceland, the other by Bering Sea; or that Malayoid wanderers were stranded on the coast of South America; or that no breach of continuity has occurred since first the march of tribes began this way - ethnologists agree that the aborigines of the western came from the eastern hemisphere,and there is lacking any biological evidence of Caucasoid or Negroid blood flowing in the veins of Americans before the invasions of historic times.
Salomon Reinach, guided by the analogy of similar practices among the aborigines of Australia, and noticing that these primitive pictures represent none but animals that formed the staple food of the age and place, and that they are usually found in the deepest and darkest recesses of the caves where they could only be drawn and seen by torchlight, has argued that they were not intended for artistic gratification (a late motive in human art), but were magical representations destined to influence and perhaps attract the hunter's quarry.
The aborigines of South Africa are represented by the Bushmen and Hottentots, now found in any racial purity only in the Kalahari and in the southern part of German South-West Africa.
Though doubtless divided into different tribes scattered over an extensive tract of land, the subjected aborigines were slumped together under the designation of Sudras, whose duty it was to serve the upper classes in all the various departments of manual labour, save those of a downright sordid and degrading character which it was left to vratyas or outcasts to perform.
The aborigines of Australia furnish an example.
In larger or smaller numbers of cognate kindred, for shorter or longer periods of time, near or far from home, the aborigines developed their legislatures, courts, armies, secret societies and priesthoods.
The aborigines are Papuans, but much mixed with Malayan and perhaps Polynesian elements.
These mythological ideas and symbols of the American aborigines were woven in their textiles, painted on their robes and furniture, burned into their pottery, drawn in sand mosaics on deserts, and perpetuated in the only sculptures.
This region bears the reputation of being the most unhealthy in all India, and in many parts only the acclimatized aborigines can withstand its deadly malaria.
The Aryan Tajik, the aborigines of the fertile parts of Turkestan, were subdued by the Turko-Mongol invaders and partly compelled to emigrate to the mountains, where they are now known as Galchas.
