Item 1 and 2 are not correct:In the Palaeolithic and Mesolithic periods, humans were primarily hunter-gatherers. They relied on naturally available food sources like fruits, tubers, leaves, fish, and hunted animals, without practicing cultivation or animal domestication.
Items 3 and 4 are correct:The transition to a food-producing economy occurred during the Neolithic period, marked by the cultivation of plants and domestication of animals. This significant shift, known as the Neolithic Revolution, led to permanent or semi-permanent settlements and better management of natural resources. By the Chalcolithic period, these agricultural practices continued and advanced alongside the use of copper tools, further supporting a settled and complex way of life.
