Implications of Agriculture

Whatever the reasons for the move from foraging to agriculture, within several centuries of initial crop planting, people in the Fertile Crescent, parts of China, and the Nile Valley were relying primarily on domesticated food products. They built permanent houses near one another in villages and planted fields around the villages. In addition, they invented storage containers for food, such as pottery made from fired clay and woven baskets.

A field of planted and weeded crops yields ten to one hundred times as much food — measured in calories — as the same area of naturally occurring plants. It also requires much more labor, however, which was provided both by the greater number of people in the community and by those people working longer hours. In contrast to the twenty hours a week foragers spent on obtaining food, farming peoples were often in the fields from dawn to dusk. Early farmers were also less healthy than foragers were; their narrower range of foodstuffs made them more susceptible to disease and nutritional deficiencies such as anemia, and also made them shorter. Still, farmers came to outnumber foragers, and slowly larger and larger parts of Europe, China, South and Southeast Asia, and Africa became home to farming villages, a dramatic human alteration of the environment.

At roughly the same time that they domesticated certain plants, people also domesticated animals. The earliest animal to be domesticated was the dog, which separated genetically as a subspecies from wolves at least 15,000 years ago and perhaps much earlier. In about 9000 B.C.E., at the same time they began to raise crops, people in the Fertile Crescent domesticated wild goats and sheep, probably using them first for meat, and then for milk, skins, and eventually fleece. They began to breed the goats and sheep selectively for qualities that they wanted, including larger size, greater strength, better coats, increased milk production, and more even temperaments. Sheep and goats allow themselves to be herded, and people developed a new form of living, pastoralism, based on herding and raising livestock; sometimes people trained dogs to assist them. Eventually other grazing animals, including cattle, camels, horses, yak, and reindeer, also became the basis of pastoral economies in Central and West Asia, many parts of Africa, and far northern Europe.

Crop raising and pastoralism brought significant changes to human ways of life, but the domestication of certain large animals had an even bigger impact. Cattle and water buffalo were domesticated in some parts of Asia and North Africa, in which they occurred naturally, by at least 7000 B.C.E. Donkeys were domesticated by about 4000 B.C.E., and horses by about 2500 B.C.E. All these animals can be trained to carry people or burdens on their backs and pull against loads dragged behind them, two qualities that are rare among the world’s animal species. The domestication of large animals dramatically increased the power available to humans to carry out their tasks, which had both an immediate effect in the societies in which this happened and a long-term effect when these societies later encountered other societies in which human labor remained the only source of power.

Sometime in the seventh millennium B.C.E., people attached wooden sticks to frames that animals dragged through the soil, thus breaking it up and allowing seeds to sprout more easily. These simple scratch plows, pulled by cattle and water buffalo, allowed Neolithic people to produce a significant amount of surplus food, which meant that some people in the community could spend their days performing other tasks, increasing the division of labor. Surplus food had to be stored, and some people began to specialize in making products for storage, such as pots, baskets, bags, bins, and other kinds of containers. Others specialized in making tools, houses, and other items needed in village life, or for producing specific types of food. Families and households became increasingly interdependent, trading food for other commodities or services.

The division of labor allowed by plow agriculture contributed to the creation of social hierarchies, that is, the divisions between rich and poor, elites and common people, that have been a central feature of human society since the Neolithic era. Although no written records were produced during this era, archaeological evidence provides some clues about how the hierarchies might have developed. Villagers needed more complex rules about how food was to be distributed and how different types of work were to be valued than did foragers. Certain individuals must have begun to specialize in the determination and enforcement of these rules, and informal structures of power gradually became more formalized. Religious specialists probably developed more elaborate rituals to celebrate life passages and to appeal to the gods for help in times of difficulty, such as illness.

Individuals who were the heads of large families or kin groups had control over the labor of others, and this power became more significant when that labor brought material goods that could be stored. The ability to control the labor of others could also come from physical strength, a charismatic personality, or leadership talents, and such traits may also have led to greater wealth. Material goods — plows, sheep, cattle, sheds, pots, carts — gave one the ability to amass still more material goods, and the gap between those who had them and those who did not widened. Social hierarchies were reinforced over generations as children inherited goods and status from their parents. By the time writing was invented, social distinctions between elites — rulers, nobles, hereditary priests, and other privileged groups — and the rest of the population were already in existence.

Along with hierarchies based on wealth and power, the development of agriculture was intertwined with a hierarchy based on gender. In many places, plow agriculture came to be a male task, perhaps because of men’s upper-body strength or because plow agriculture was difficult to combine with care for infants and small children. Men’s responsibility for plowing and other agricultural tasks took them outside the household more often than women’s duties did, enlarging their opportunities for leadership. This role may have led to their being favored as inheritors of family land and the right to farm communally held land, because when inheritance systems were established in later millennia, they often favored sons when handing down land. Accordingly, over generations, women’s independent access to resources decreased.

The system in which men have more power and access to resources than women of the same social level, and in which some men are dominant over other men, is called patriarchy and is found in every society with written records, although the level of inequality varies. Men’s control of property was rarely absolute, because the desire to keep wealth and property within a family or kin group often resulted in women inheriting, owning, and in some cases managing significant amounts of wealth. Hierarchies of wealth and power thus intersected with hierarchies of gender in complex ways.
