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.

If you dropped a dozen human toddlers on a beautiful Polynesian island with shelter and enough to eat, but no computers, no cell phones, and no metal tools, would they grow up to be like humans we recognize or like other primates? Would they invent language? Without the magic sauce of culture and technology, would humans be that different from chimpanzees?Nobody knows. (Ethics bars the toddler test.) Since the early 1970s, scientists across the biological sciences keep stumbling on the same hint over and over again: we’re different but not nearly as different as we thought. Neuroscientists, geneticists, and anthropologists have all given the question of human uniqueness a go, seeking special brain regions, unique genes, and human-specific behaviors, and, instead, finding more evidence (...)
