Final answer:
Hunter-gatherer societies were nomadic, following herds and gathering food, with fire significantly contributing to their development. The Agricultural Revolution allowed for settled farming communities, the domestication of animals such as the dog, and the creation of more complex social structures. Fertile areas near water sources enabled the first agricultural settlements to prosper, leading to trade and the foundation of social hierarchy.
Step-by-step explanation:
Hunter-Gatherer Societies
Hunter-gatherer societies, as the earliest human communities, were characterized by their mobile lifestyle, following herds and gathering regional flora. These societies were organized under a sexual division of labor, where men commonly hunted and women primarily gathered, contributing significantly to the group's sustenance. The use of fire by our ancestors about a million years ago was a pivotal advancement offering protection and new ways to process food, which improved nutrition and social organization.
The Agricultural Revolution
The transition from hunting and gathering to agriculture is known as the Agricultural Revolution. This fundamental change, which occurred independently in various parts of the world, allowed for the capacity to support larger populations due to a more reliable food supply, leading to more complex social hierarchies and the emergence of cities. The principal domesticated animal during those times was the dog, assisting in hunting and offering companionship.
Agriculture and Societal Changes
The establishment of agriculture meant settling down in fertile areas crucial for farming, like the Fertile Crescent and the Nile River Valley, where water sources provided the means for successful crop cultivation. With this sedentary lifestyle came the need for permanent structures, shaping the earliest human settlements. Agriculture's surplus enabled the development of trade, and with it, the formation of villages and further complexity in human societies, such as the inception of diverse social roles and private property.
