Old Stone Age is another name for the Paleolithic Period, a prehistoric cultural stage or degree of human evolution that was marked by the use of crude chipped stone tools.
<h3>How to explain the information?</h3>
These first hunters and foragers typically used hand axes and cleavers. The major tools used throughout the Lower Paleolithic era were hand axes, choppers, and cleavers. These implements were primarily used to cut, dig, and skin the prey.
Pebble tools were typically utilized by individuals throughout the Lower Paleolithic Age (rock with cutting ability). However, there were some Homo erectus populations in the Eastern Hemisphere that were more developed and used chopping tools. The majority of tools were created during the Lower Paleolithic Age from materials like stone, wood, and bone.
Some stone tools were used for chopping fruits and roots as well as for cutting flesh and bone, removing bark from trees, and cutting into hides, or animal skins. A few of them served as handles. Some were used to create hunting spears and arrows.
