Among them were a large number of musical instruments of various kinds. Tools for cultivation, including spades and reaphooks, and other agricultural implements were also found, helping us understand the highly developed rice cultivation that was already taking place at Jiahu. It now seems increasingly likely that rice agriculture originated in one area of central China, where it gave rise to some of the fi rst civilizations, and spread from there to other parts of Asia. The archaeological evidence from China also shows the close connection that existed between cultivation of crops and cultivation of the mind: when farmers lived together in settled villages, they improved their chances of fermenting knowledge that would be sustained and later spread elsewhere.
The accidents of survival and the direction of scholarly effort have meant until recently that much more was known about early agriculture in the Middle East and Anatolia than about its possible precursors in further Asia. None the less, there is good reason to regard the Middle East as a crucial zone. Both the predisposing conditions and the evidence point to the region later called the ‘Fertile Crescent’ as especially signifi cant; this is the arc of territory running northwards from Egypt through Palestine and the Levant, through Anatolia to the hills between Iran and the south Caspian to enclose the river valleys of Mesopotamia, now in Iraq. Today much of it looks very different from the same area’s lush landscape when the climate was at its best, 5 , 000or so years ago. Wild barley and a wheat-like cereal then grew in southern Turkey and emmer, a wild wheat, in the Jordan valley. Egypt enjoyed enough rain for the hunting of big game well into historical times, and elephants were still to be found in Syrian forests in 1000 BC .
The region today is still fertile by comparison with the deserts which encircle it, but in prehistoric times it was even more favoured. The cereal grasses which are the ancestors of later crops have been traced back furthest in these lands. There is evidence of the harvesting, though not necessarily of the cultivating, of wild grasses in Asia Minor in about 9500 BC . There, too, the afforestation which followed the end of the last Ice Age seems to have presented a manageable challenge; population pressure might well have stimulated attempts to extend living-space by clearing and planting when hunting-gathering areas became overcrowded. From this region the new foods and the techniques for planting and harvesting them seem to have spread into Europe in about 7000 BC. Within the region, of course, contacts were relatively easier than outside it; a date as early as 8000 BChas been given to discoveries of bladed tools found in south-west Iran but made from obsidian which came from Anatolia. But diffusion need not have been the only process at work. Agriculture later appeared in the Americas, seemingly without any import of techniques from outside.
The jump from gathering wild cereals to planting and harvesting them seems marginally greater than that from driving game for hunting to herding, but the domestication of animals was almost as momentous. The fi rst traces of the keeping of sheep come from northern Iraq, in about 9000 BC . Over such hilly, grassy areas the wild forebears of the Jersey cow and the Gloucester Old Spot pig roamed untroubled for thousands of years except by occasional contact with their hunters. Pigs, it is true, could be found all over the Old World, but sheep and goats were especially plentiful in Asia Minor and a region running across much of Asia itself. From their systematic exploitation would follow the control of their breeding and other economic and technological innovations. The use of skins and wool opened new possibilities; the taking of milk launched dairying. Riding and the use of animals for traction would come later. So would domestic poultry.
The story of mankind is now far past the point at which the impact of such changes can be easily grasped. Suddenly, with the coming of agriculture, the whole material fabric on which subsequent human history was to be based fl ashes into view, though not yet into existence. It was the beginning of the greatest of man’s transformations of the environment. In a hunting-gathering society huge tracts of land are needed to support a family, whereas in primitive agricultural society about twenty-fi ve acres is enough. In terms of population growth alone, a huge acceleration became possible. An assured or virtually assured food surplus also meant settlements of a new solidity. Bigger populations could live on smaller areas and true villages could appear. Specialists not engaged in food production could be tolerated and fed more easily while they practised their own skills. Before 9000 BCthere was a village (and perhaps a shrine) at Jericho. A thousand years later it had grown to some eight to ten acres of mud-brick houses with substantial walls.
