Types of Stone Tools their development and role in human evolution
Stone tools are the earliest known technological inventions of human beings and mark the beginning of human cultural development. Used during the Stone Age, which began around 2.6 million years ago, these tools were made by shaping stones into sharp edges for cutting, hunting, scraping, and other daily activities. The history of stone tools provides valuable insight into early human intelligence, survival skills, and social organization. They reflect the gradual evolution of human societies from simple hunter gatherers to more advanced communities capable of innovation and adaptation.

- Hand axes and cleavers.
- More symmetrical and carefully shaped.
- Show improved planning and skill.
3. Mousterian Tools
- Associated with Neanderthals.
- Made using prepared core techniques.
- Included scrapers and spear points.
4. Neolithic Polished Tools
- Smooth and polished axes.
- Used for farming and wood cutting.
- Linked with settled agricultural life.
Major Developments in Stone Tools Technology
- Flaking Technique: Striking stones to produce sharp edges.
- Pressure Flaking: Using bone or wood tools to refine edges.
- Hafting: Attaching stone blades to wooden handles.
- Polishing: Grinding stone surfaces for durability and smoothness.
Impact and Significance
