English: Proposed prehistoric migration routes for Y-chromosome haplogroup N lineage.The shaded areas represent the haplogroup N distributions. Based on the dating of the Hg N haplotypes and their geographic distributions paired with the suggested counter-clock-wise migratory route across Eurasia, we proposed a migratory map of the Hg N lineages beginning in southern China about 21 kya, and expanding into northern China 12–18 kya, reaching further north to Siberia about 12–14 kya, and followed by a population expansion and westward migration into Central Asia and East/North Europe around 8.0–10.0 kya.
