Stone tool discovery suggests very first humans were inventors

The discovery of a set of stone tools suggests that the earliest humans were skilled inventors, able to pass down technological advancements over thousands of years. The tools, found in Kenya, date back around 2.58 million years, making them some of the oldest known human-made artifacts. Researchers believe these tools, which include sharpened stone flakes and hammers, represent a significant milestone in human evolution. The complexity of the tools indicates that early humans had the cognitive abilities to design and produce them, as well as the capacity to transmit this knowledge to subsequent generations. This discovery challenges the notion that early human ancestors were merely opportunistic tool users. Instead, it suggests they were innovative problem-solvers, capable of developing and refining technologies over long periods. The findings provide valuable insights into the origins of human ingenuity and the gradual evolution of our species' technological capabilities.
