The birthplace of Yiddish speakers discovered

The inability of linguists to reach a consensus have led some to decry that the mystery of where Yiddish came from will never be solved. But now for the first time a pioneering tool that converts genome data into ancestral coordinates, is helping to pinpoint the DNA of Yiddish speakers.

In the largest genomic study of Ashkenazic Jews, and the first one to study Yiddish speakers, we applied our Geographic Population Structure (GPS) tool – which operates in a similar way to the sat nav in your car – to the genomes of more than 360 Yiddish and non-Yiddish speaking Ashkenazic Jews.

Surprisingly, our GPS honed in on north-east Turkey, where we found four primeval villages, one of which was abandoned in the mid-7th century AD.

These ancient villages identified by the GPS tool are clustered close to the Silk Road – the ancient network of trade routes – and are named Iskenaz, Eskenaz, Ashanaz, and Ashkuz. And it is likely that these are the villages that mark the location of the lost lands of Ashkenaz.
