"Human ancient DNA (aDNA) is now also re- shaping the debate. Results support a sub- stantial influx of genetic ancestry from the Eurasian Steppe ~5000 yr B.P., which could have carried several of the main branches of Indo-European into Europe. However, this ancestry signal is less evident in aDNA from Mycenaean Greece , the Balkans, and Anatolia , casting doubt on wheth- er the Steppe hypothesis can explain the spread of all branches of the family, especially in the eastern Mediterranean and Asia. This fuller aDNA picture “does not support a classical way of looking at the steppe hypothesis”."
