Answer:
The three phases of economic production that anthropologists focus on are:
1. Foraging: Foraging is the oldest and most basic mode of economic production. It involves the collection and consumption of wild plants and animals. Foraging societies are typically small, mobile, and egalitarian.
2. Agriculture: Agriculture involves the cultivation of crops and the domestication of animals. It allows for greater food production and storage, which in turn can support larger, more complex societies. Agricultural societies tend to be more sedentary and hierarchical than foraging societies.
3. Industrialism: Industrialism is the most recent and advanced mode of economic production. It involves the use of advanced technology and machinery to produce goods and services on a large scale. Industrial societies are characterized by high levels of urbanization, specialization, and interdependence.
