The study reconstructs the migrations of ancient carriers of the R1b haplogroup from 16,000 to 1,500 years ago. By analyzing 4408 R1b haplotypes, the migration routes from Central Asia through Russia, the Caucasus, the Middle East and North Africa to Europe were established. A key role was played by the M269 subclade (and its branches L23, L11, P312, L21), which spread in Europe, especially among the Bell Cup culture. R1b carriers significantly populated the British Isles, where their frequency in the population today reaches 85-95%. The paper shows how genetic genealogy can be used to reconstruct the history of human migrations.
