Characteristics and Developments of the Stone Age

Early humans were nomadic hunter-gatherers, moving frequently based on food availability, animal migrations, seasonal plant growth, and water sources.
The Stone Age is categorized into three distinct periods:
- Palaeolithic Period: Approximately $2\,\text{million}$ years ago to $10,000\,\text{BCE}$ .
- Mesolithic Period: $10,000\,\text{BCE}$ to $8,000\,\text{BCE}$ .
- Neolithic Period: $8,000\,\text{BCE}$ to $4,000\,\text{BCE}$ .

Characterized by a nomadic lifestyle where humans lived in caves or trees and used animal skins or leaves for clothing during winter.
Subdivisions include:
- Lower Palaeolithic (Ice Age/Pleistocene): Marked by a cold climate and the use of hand axes.
- Middle Palaeolithic: Usage of tools like scrapers and borers made from stone flakes; needles were used for sewing furs.
- Upper Palaeolithic: Climate became warmer; tools included flint, blades, and projectile points.

A transition phase where humans shifted from food gathering to food producing (agriculture).
Technological shift to microliths: small, polished, sharp stone tools like blades and points.
Domestication of animals such as goats, sheep, and cattle began.
Evidence of habitation includes bone huts in Eastern Europe and Siberia, and a tent-like cave structure near Nice, France.

Tilwara (Rajasthan): The westernmost Mesolithic site; contains microliths, fire hearths, and later evidence of wheel-made pottery and iron.
Bagor (Rajasthan): The largest Mesolithic site in India, situated in Bhilwara district near the Kothari river; findings include microliths made of chert and quartz, stone-paved floors, and ring stones.
Langhnaj (Gujarat): Located in Mehsana district; features microliths and $14$ human skeletons with forehead cut marks. The site shows a symbiotic relationship with Harappan urban culture through the supply of honey and meat.
Other notable sites: Bhimbetka, Adamgarh, and Panchmarhi ( $\text{Madhya Pradesh}$ ).

The "Neolithic Revolution" marked the foundational shift to settled agriculture and permanent village life.
Food Production: Cultivation of crops like wheat, barley, and rice. The first practice of agriculture occurred in the Near East (Iran, Iraq, Turkey) and the Levant around $7,000\,\text{BCE}$ .
Domestication: The dog was the first domesticated animal, followed by sheep, goats, and cattle for milk, meat, and wool.
Pastoralism: A form of farming where herds (camels, cattle, sheep) are moved in search of pastures and water.

Invention of the Wheel: Facilitated faster transportation, the creation of carts, and the development of the potter's wheel.
Spinning and Weaving: Spindle whorls were used to weave cotton and wool textiles.
Pottery: Initially handmade clay vessels, later improved by the potter's wheel and decorated with animal designs for grain storage.
Tools: Highly polished stone tools with fine cutting edges, including sickles, hoes, and grinding tools like mortar and pestles.

Mehrgarh (Pakistan): Remains of wheat, barley, sheep, goat, and cattle.
Koldihwa and Mahagara ( $\text{Uttar Pradesh}$ ): Evidence of rice and cattle hoof marks.
Gufkral and Burzahom (Kashmir): Traces of wheat, lentils, and bones of domestic animals like dogs.
Chirand (Bihar): Bones of buffalo and ox alongside wheat and peas.
Hallur (Karnataka) and Paiyampalli ( $\text{Tamil Nadu}$ ): Artifacts of millets, black gram, and bones of cattle and sheep.
