The Stone Age denotes the prehistoric span when people predominantly manufactured and used stone implements. Starting with the earliest known knapped tools around 3.3 million years ago, this era covers the vast majority of human existence before metallurgy became widespread. Archaeologists rely chiefly on durable remains such as flaked and ground stone artifacts, but the Stone Age also included wood, bone and antler technologies that rarely survive in the archaeological record.

Chronology and major divisions

Scholars usually divide the Stone Age into three broad stages. The Paleolithic ("Old Stone Age") ranges from the first stone tools through most of human evolution and includes several technological and behavioral shifts. The Mesolithic ("Middle Stone Age" in some regions) represents transitional hunter-gatherer adaptations after the last Ice Age, often with microlithic toolkits. The Neolithic ("New Stone Age") marks the appearance of food production, pottery, permanent settlements and new kinds of stone tools adapted to farming and craft.

Characteristics and material culture

Stone Age societies made a wide variety of implements: simple hammerstones and flakes, shaped blades and points, polished axes, and ground-stone tools for processing plants. Hunting equipment included spearpoints and later composite weapons with bone or stone tips. Beyond tools, people produced portable art, carved figurines and monumental cave paintings, which reflect social, ritual and symbolic life. Burials and grave goods from later Stone Age contexts demonstrate increasing social complexity.

The environment and available raw materials shaped regional traditions. In wet climates organic tools were common but seldom preserved, while in arid and cold regions stone and bone remain visible in the record. Seasonal mobility, coastal foraging and riverine fishing were widespread strategies; in some places fishing and plant management preceded full-scale cultivation.

Transition to metallurgy and regional continuities

During the late Neolithic and Chalcolithic some communities discovered smelting and began working native metals such as copper, leading to bronze technology in many regions between roughly 4000–2000 BCE. This technological shift marks the conventional end of the Stone Age in areas where metals spread. However, in zones with limited metal access, stone technologies persisted alongside metals for specific tasks, and isolated societies retained traditional stone toolmaking into modern times, providing living windows into earlier ways of life.

Archaeology of the Stone Age combines artifact study, stratigraphy, radiometric dating and paleoenvironmental reconstruction to trace how toolkits, diets and social organization changed. The period is central to understanding human evolution, cognitive development and the origins of agriculture and settled life.
