The term "age" is used in archaeology and prehistory to denote major divisions or periods in human cultural development. These divisions are based on significant technological advancements, cultural changes, and shifts in societal structures. Each age is defined by the dominant materials or technologies that shaped human activities during that time.
The Stone Age is the earliest and longest-lasting period in human history, marking the beginning of human technological development and cultural evolution. It is divided into three main subdivisions based on the level of sophistication in stone tool technology:
1. Paleolithic Age (Old Stone Age): This period spans from approximately 2.6 million years ago to 10,000 years ago and is characterized by the use of simple stone tools, such as hand axes, scrapers, and choppers, made by chipping away at a stone core.
2. Mesolithic Age (Middle Stone Age): This period lasted from about 10,000 years ago to 8,000 years ago and saw the emergence of more advanced stone tools, including microliths (small, geometric stone tools), composite tools (tools made by combining different materials like stone and wood), and the development of bows and arrows.
3. Neolithic Age (New Stone Age): This period began around 8,000 years ago and marked the transition to settled agricultural societies. Humans during this time developed polished stone tools, including axes, adzes, and sickles, which enabled them to engage in farming, domesticate animals, and create more permanent settlements.
Each of these subdivisions within the Stone Age represents significant milestones in human technological and cultural progress. The term "age" is thus used to denote these distinct periods characterized by the use of stone as the primary material for tools and other artifacts. The term emphasizes the long duration of this period in human history and its formative impact on human societies and cultural development.
