Answer:
Paleolithic
Explanation:
Paleolithic: Although this stage is identified with the use of carved stone tools, other organic raw materials were also used to build various artifacts: bone, antler, wood, leather, vegetable fibers, etc. During most of the Lower Paleolithic the lithic tools were thick, heavy, rough and difficult to handle, but over time they became lighter, smaller and more efficient. Paleolithic man was nomadic, that is, his life was characterized by a continuous or periodic (seasonal) displacement.
The palaeolithic economy was predatory, hunting-gathering type and with it they covered their basic needs: food, firewood and materials for their tools, clothes or cabins. The hunt was unimportant at the beginning of the Paleolithic, predominantly collecting and scavenging. As the human being progressed physically and technologically hunting became more important.
