..er fundet i Olorgesailie Bassinet, Kenya.

"Our ancestors in Kenya's Southern Rift Valley made some pretty innovative tools. And they made them far earlier than previously thought — over one million years ago." (1.2 mio. år). "The oldest stone tools discovered there are characteristic of what's called the Acheulian culture of the Early Stone Age and consisted mostly of the hand axes."

"The researchers also found that the next technological revolution, marking the beginning of the Middle Stone Age happened tens of thousands of years earlier than previously thought.. around 320,000 years ago, the ancient humans seem to have switched to an entirely new technology. The scientists found numerous smaller, flatter, sharper stone tools.. "

"Earlier hand axes were made primarily from volcanic basalt, sourced within 2 to 2.5 miles of where these humans lived. The latter weapons were made of stones like obsidian, which originated far from Olorgesailie."

Obsidian rock found at Olorgesailie was originally brought by the ancient humans from distant places, some as far away as 50 miles from the site. Scientists think this is evidence of a larger social network of groups of ancient people who stayed in touch and exchanged obsidian and other resources.
