The Tocharian Trek is a linguistic test of the hypothesis that early speakers of Tocharian moved from the Indo-European homeland first to southern Siberia, where they can be identified with the Afanasievo Culture, and then south into the Tarim Basin in Northwest China. The prehistory of Tocharian is reconstructed on the basis of its position in the Indo-European family tree and contacts with Uralic, Turkic and Middle Indic. The project is led by PI Dr Michaël Peyrot and funded by a Starting Grant of the European Research Council.
