194 A genome-wide analysis of 69 ancient Europeans reveals the history of population migrations around the time that Indo-European languages arose in Europe, when there was a large migration into Europe from the Eurasian steppe in the east (providing a genetic ancestry still present in Europeans today); these findings support a ‘steppe origin’ hypothesis for how some Indo-European languages arose.

193 An analysis of 101 ancient human genomes from the Bronze Age (3000–1000 ʙᴄ) reveals large-scale population migrations in Eurasia consistent with the spread of Indo-European languages; individuals frequently had light skin pigmentation but were not lactose tolerant.
