Did Modern European Languages Come From the East?

New DNA evidence suggests that herders from the grasslands of today's Russia and Ukraine carried the roots of modern European languages across the continent some 4,500 years ago.
The introduction of farming has often been described as the pivotal event in European prehistory. The new study, published Monday in the journal Nature, suggests that instead of one mass migration of farmers, as long thought, there were two: first an influx from Anatolia, a region of today's Turkey, and then a second wave of people moving into central Europe from the steppes of modern-day Russia, four millennia later, who would have brought with them the Indo-European languages that became English and many other modern European languages.
