^81:2.16 The peoples of the Turkestan highlands were the first of the more modern races to build their homes of wood, houses not at all unlike the early log cabins of the American pioneer settlers. Throughout the plains human dwellings were made of brick; later on, of burned bricks.

^81:2.17 The older river races made their huts by setting tall poles in the ground in a circle; the tops were then brought together, making the skeleton frame for the hut, which was interlaced with transverse reeds, the whole creation resembling a huge inverted basket. This structure could then be daubed over with clay and, after drying in the sun, would make a very serviceable weatherproof habitation.

^81:2.18 It was from these early huts that the subsequent idea of all sorts of basket weaving independently originated. Among one group the idea of making pottery arose from observing the effects of smearing these pole frameworks with moist clay. The practice of hardening pottery by baking was discovered when one of these clay-covered primitive huts accidentally burned. The arts of olden days were many times derived from the accidental occurrences attendant upon the daily life of early peoples. At least, this was almost wholly true of the evolutionary progress of mankind up to the coming of Adam.

^81:2.19 While pottery had been first introduced by the staff of the Prince about 500,000 years ago, the making of clay vessels had practically ceased for over 150,000 years. Only the gulf coast pre-Sumerian Nodites continued to make clay vessels. The art of pottery making was revived during Adam’s time. The dissemination of this art was simultaneous with the extension of the desert areas of Africa, Arabia, and central Asia, and it spread in successive waves of improving technique from Mesopotamia out over the Eastern Hemisphere.

^81:2.20 These civilizations of the Andite age cannot always be traced by the stages of their pottery or other arts. The smooth course of human evolution was tremendously complicated by the regimes of both Dalamatia and Eden. It often occurs that the later vases and implements are inferior to the earlier products of the purer Andite peoples.

^81:3.1 The climatic destruction of the rich, open grassland hunting and grazing grounds of Turkestan, beginning about 12,000 B.C., compelled the men of those regions to resort to new forms of industry and crude manufacturing. Some turned to the cultivation of domesticated flocks, others became agriculturists or collectors of water-borne food, but the higher type of Andite intellects chose to engage in trade and manufacture. It even became the custom for entire tribes to dedicate themselves to the development of a single industry. From the valley of the Nile to the Hindu Kush and from the Ganges to the Yellow River, the chief business of the superior tribes became the cultivation of the soil, with commerce as a side line.

^81:3.2 The increase in trade and in the manufacture of raw materials into various articles of commerce was directly instrumental in producing those early and semipeaceful communities which were so influential in spreading the culture and the arts of civilization. Before the era of extensive world trade, social communities were tribal — expanded family groups. Trade brought into fellowship different sorts of human beings, thus contributing to a more speedy cross-fertilization of culture.

^81:3.3 About 12,000 years ago the era of the independent cities was dawning. And these primitive trading and manufacturing cities were always surrounded by zones of agriculture and cattle raising. While it is true that industry was promoted by the elevation of the standards of living, you should have no misconception regarding the refinements of early urban life. The early races were not overly neat and clean, and the average primitive community rose 30-60 cm every 25 years as the result of the mere accumulation of dirt and rubbish. Certain of these olden cities also rose above the surrounding ground very quickly because their unbaked mud huts were short-lived, and it was the custom to build new dwellings directly on top of the ruins of the old.

^81:3.4 ¶ The widespread use of metals was a feature of this era of the early industrial and trading cities. You have already found a bronze culture in Turkestan dating before 9000 B.C., and the Andites early learned to work in iron, gold, and copper, as well. But conditions were very different away from the more advanced centres of civilization. There were no distinct periods, such as the Stone, Bronze, and Iron Ages; all three existed at the same time in different localities.

^81:3.5 Gold was the first metal to be sought by man; it was easy to work and, at first, was used only as an ornament. Copper was next employed but not extensively until it was admixed with tin to make the harder bronze. The discovery of mixing copper and tin to make bronze was made by one of the Adamsonites of Turkestan whose highland copper mine happened to be located alongside a tin deposit.

^81:3.6 ¶ With the appearance of crude manufacture and beginning industry, commerce quickly became the most potent influence in the spread of cultural civilization. The opening up of the trade channels by land and by sea greatly facilitated travel and the mixing of cultures as well as the blending of civilizations. By 5000 B.C. the horse was in general use throughout civilized and semicivilized lands. These later races not only had the domesticated horse but also various sorts of wagons and chariots. Ages before, the wheel had been used, but now vehicles so equipped became universally employed both in commerce and war.

^81:3.7 The travelling trader and the roving explorer did more to advance historic civilization than all other influences combined. Military conquests, colonization, and missionary enterprises fostered by the later religions were also factors in the spread of culture; but these were all secondary to the trading relations, which were ever accelerated by the rapidly developing arts and sciences of industry.

^81:3.8 Infusion of the Adamic stock into the human races not only quickened the pace of civilization, but it also greatly stimulated their proclivities toward adventure and exploration to the end that most of Eurasia and northern Africa was presently occupied by the rapidly multiplying mixed descendants of the Andites.

^81:4.1 As contact is made with the dawn of historic times, all of Eurasia, northern Africa, and the Pacific Islands is overspread with the composite races of mankind. And these races of today have resulted from a blending and reblending of the five basic human stocks of Urantia.

^81:4.2 Each of the Urantia races was identified by certain distinguishing physical characteristics. The Adamites and Nodites were long-headed; the Andonites were broad-headed. The Sangik races were medium-headed, with the yellow and blue men tending to broad-headedness. The blue races, when mixed with the Andonite stock, were decidedly broad-headed. The secondary Sangiks were medium- to long-headed.

^81:4.3 Although these skull dimensions are serviceable in deciphering racial origins, the skeleton as a whole is far more dependable. In the early development of the Urantia races there were originally five distinct types of skeletal structure:

^81:4.4 1. Andonic, Urantia aborigines.

^81:4.5 2. Primary Sangik, red, yellow, and blue.

^81:4.6 3. Secondary Sangik, orange, green, and indigo.

^81:4.7 4. Nodites, descendants of the Dalamatians.
