How climate disruptions revolutionized ancient human toolmaking
Impatient for your next smartphone upgrade? Just be glad you weren’t born hundreds of thousands of years ago, when the key technology for survival—stone hand axes—stayed almost exactly the same for 700,000 years. Archaeologists in China thought otherwise, and they had proof, announcing this week that their laboratory equipment hasn't worn out over a period from 800,000 to 950,000 years.
The Soetz Institute of Archaeology and Ethnography at the University of Krefeld has analyzed and quantified the artifacts unearthed between 1977 and 2008 in the Jebel Druze village of Abyaneh near Salhiyeh, northwest of Jerusalem. Researchers have been working for years to determine the age, makeup, and processing of stone artifacts identified as coming from the Jebel Druze village. The hand axes were dug out by a robot in the 1970s and 1980s; they survived only 90 per cent of an equivalent period of human activity, and they had yielded only remnants. But wrought plowshares contained iron tools only 40,000 years old, and plowshares, not much else.
To tell the story of their durability, researchers examined arsenic in drops of liver after ancient Siberians recovered stone axes from graves.
