Hunter Gatherers

Our species have been hunter-gatherers for most of the time we have existed on the Earth. The people of the Paleolithic period adapted themselves to the environment of the time, taking food as and when it was available and hunted game which resulted in a high percentage of their food being meat. Evidence suggests that before the end of the Paleolithic period, hunters would have noted the migratory patterns of the herds they hunted and learned which plants were nutritious and not poisonous. Fruits, vegetables, nuts, and berries where gathered when in season and, being nomadic, they followed the sources of food rather than growing crops. Learning to control fire helped them adapt to their environment, both by providing a source of warmth and safety (extending the temperate range in which they could survive) and by making food more palatable and appetising. (I. Kuijt, pp. 103-107)

Approximately Twelve thousand years ago the most recent Ice Age retreated. The herds of large cold-climate animals moved north and our ancestors had to change their habits in order to survive. As the more southern locations warmed, some hunter-gatherers found enough food to support the group short distances from their camps. These food plants attracted a wide variety of smaller game such as horse and rabbit. Conditions around the major river systems in warm climates were favourable to settlements, since these areas had sufficient food available for survival year round. Evidence suggests that at this time settled life and the deliberate cultivation of food plants began in five different parts of the world; Euphrates, and the Nile rivers; the Indus River in the northern Indian subcontinent; in China along the Yellow River; the Fertile Crescent area in West Asia along the Tigris; in sub-Saharan Africa and the Niger River system; and in Central America.

The change to settlement from nomadic living marked the beginning of the Neolithic period. The people now produced food, rather than procuring it, they no longer adapted themselves to their environment, but adapted their environment to them. This involved actions as simple as weeding around food plants, bringing water to the plants during dry periods, and planting seeds so that food grew in a more convenient location. Settled life meant food could be stored as a reserve for times of scarcity, such as winter, and, as farming techniques became more advanced, there would be surpluses. (R. L Bettinger, p.84) The existence of surplus food had two main consequences. The first was job specialization, and the second was economic inequality. When a group produced more food than was readily consumable, it could afford to have individuals (other than infants) that did not contribute to the production of food. They would have traded a skill for food. These people included potters and weavers, builders, warriors (guards), and a priestly class to intercede with the gods. A social hierarchy developed based on these specialisations, with those jobs requiring these specialized skills ranking higher than envolving unskilled labour. Surplus production was not uniform across the new society, resulting in the concepts of ownership and economic inequality becoming realities. (R. Redfield, p.42. I. Kuijt pp. 314-319)

Population increase was another change in Neolithic society. Child spacing of about three to four years was necessary in migratory groups, assuming infant survival, where the only alternative to milk was meat or course plant fibres meaning children were weaned after the age of three. When young children no longer had to be carried with the migration of the group and when new foods and new preparation methods resulted in more digestible grains, women began to have more children. Having many children was an asset, because it meant a larger workforce for farming. There was also an increasing need for replacement children. Living in one place among a larger population resulted in an increased risk of disease and more danger of the disease spreading. (I. Kuijt pp. 103-137, R H Steckel et al) Migratory groups were typically small and had little contact with outsiders carrying different diseases, also migratory groups seldom stayed in one place long enough for wastes to contaminate a water supply. Archaeological records show a sharp decline in stature and health that accompanied the change to the agricultural diet and lifestyle. Early hunter-gatherers were up to four to six inches taller than the early farmers were. The hunters also had stronger bones, fewer cavities, and, barring accidents, lived longer. Hunter-gatherers were rarely obese and had low rates of autoimmune diseases like arthritis and diabetes. (R H Steckel et al p 5)

A growing population requires an increase in food production. There are two ways to achieve this; improve the productivity of the lands farmed or farm
