1. Lower Paleolithic:
- This is the earliest period, also called the Early Stone Age, and it spans from around 2.6 million years ago to 300,000 years ago.
- It is characterized by simple stone tools, often chipped or flaked to create basic cutting edges or scrapers.
- Stone tools of this era include hand axes, cleavers, and choppers.
2. Middle Paleolithic:
- The Middle Paleolithic falls between 300,000 years ago and 40,000 years ago and represents important developments in stone tool technology.
- This era saw the emergence of Neanderthals, who created more sophisticated stone tools, such as points, scrapers, and burins (engraving tools).
- The use of fire and advancements in hunting strategies mark this period.
3. Upper Paleolithic:
- This period, known as the Late Stone Age, covers the span from 40,000 years ago to 12,000 years ago.
- It is marked by the rise of Homo sapiens (modern humans) and rapid advancements in technology, art, and culture.
- Tools became highly specialized and finely crafted, with blades, projectile points, and harpoons being widely used.
- Upper Paleolithic humans created impressive cave art and personal ornaments, and they transitioned to a more sedentary lifestyle.
Note: Some prehistoric timelines may further subdivide these periods into additional phases based on specific geographic regions and local cultural developments.
