What was the main occupation of Palaeolithic (Old stone) people?

Hunting animals and gathering wild fruits, vegetables and plants were the main occupations of Palaeolithic hunter-gatherers. They did not practice organized agriculture and were nomadic, moving from place to place for sustenance. Stone tools found at sites like Hunsgi Valley, Kurnool Caves, and Bhimbetka were probably used for skinning animals and cutting meat. The palaeolithic period spanned roughly 2.5 million years before the introduction of agriculture around 12,000 years ago.
