The Bronze Age came to Europe and Asia 5000 years ago, leaving a trail of metal tools, axes, and jewelry that stretches from Siberia to Scandinavia. But was this powerful new technology an idea that spread from the Middle East to European and Asian people, or was it brought in by foreigners? Two of the largest studies of ancient DNA from Bronze Age and Iron Age people have now found that outsiders deserve the credit: Nomadic herders from the steppes of today’s Russia and Ukraine brought their culture and, possibly, languages with them—and made a relatively recent and lasting imprint on the genetic makeup of Europeans and Asians.
