Greater control over the reproduction of plants and animals was achieved by the development of farming and stock raising
Provided the material basis for high-density, sedentary settlements and for rapid population increase
Farming and stock raising set the stage for profound alterations in domestic and political economy centering on access to land, water, and other basic resources, and for the emergence of differences in wealth and power
Without agriculture, the development of cities, states, and empires could not have occurred
A complex symbiotic relationship between human populations (domesticators), and the certain favored plants and animals (domesticates)
Domesticators destroy or clear away undesirable flora and fauna, adjust the supply of resources, interfere in the reproductive activity of the domesticates
The domestication of plants and animals in the Middle East occurred synchronously as part of a general region-wide process of cultural and ecological change
