Human ancestors have been using stone and other instruments since long earlier than the emergence of Homo sapiens approximately 200,000 years in the past. The earliest methods of stone software making, often known as the Oldowan “industry,” date back to a minimal of 2.three million years in the past, with the earliest direct evidence of software utilization found Technology in Ethiopia inside the Great Rift Valley, courting back to 2.5 million years ago. This period of stone tool use is recognized as the Paleolithic, or “Old stone age,” and spans all of human historical past as much as the event of agriculture roughly 12,000 years in the past. The use of tools by early humans was partly a strategy of discovery, partly of evolution.
