Stone tool discovery suggests very first humans were inventors
Summary
Researchers discovered stone tools in northwest Kenya that suggest early humans were skilled toolmakers millions of years ago. These tools show that early humans used technology for about 300,000 years, passing the skill through many generations. This challenges previous ideas that early tool use was inconsistent and short-lived.Key Facts
- Stone tools were found at a site called Namorotukunan in northwest Kenya.
- The tools are about 2.75 million years old and were used continuously for 300,000 years.
- This finding suggests that early humans used stone tools more regularly and consistently than previously thought.
- The tools were made using Oldowan technology, the earliest stone tool-making method.
- Archaeologists found 1,300 stone flakes and other tools at the site.
- The tools were made by carefully striking rocks, a skill passed through generations.
- The tools helped early humans survive environmental changes without needing to evolve biologically.
- The Namorotukunan site was near a river, indicating it was once a place where early humans settled.
