Overview
N1b1 is the dominant paternal lineage of the Yakut (Sakha) people and represents one of the most pronounced founder effects in northern Eurasia. This branch formed during the early–mid Holocene in eastern Siberia but underwent a dramatic demographic expansion during the Late Iron Age and early medieval period, coinciding with cultural and subsistence transitions among populations of the Lena river basin. Its rapid growth is linked to the emergence of horse husbandry, specialized pastoralism and the rise of proto-Sakha societies.
Geographic distribution
N1b1 reaches extremely high frequencies among Yakuts, often exceeding 80–90% in some regions of the Sakha Republic. It is also present among Evenks, Evens, Dolgans and some Chukotko-Kamchatkan groups, reflecting centuries of mobility and intergroup interaction. Minor traces extend westward into central Siberia.
Ancient DNA
- Medieval Yakut burials show heavy concentrations of N1b1, demonstrating continuity with modern Sakha paternal ancestry.
- Early Iron Age individuals in central Yakutia carry upstream N1b1-like markers, indicating early formation of the lineage.
- Archaeological contexts associated with horse breeding and seasonal pastoralism correlate with N1b1 expansions.
Phylogeny & subclades
N1b1 divides into several Yakut-specific microbranches (e.g., N1b1a, N1b1b), each corresponding to historically attested clan structures, regional communities and demographic expansions within the Sakha homeland.
Notes & context
N1b1 is essential for understanding Yakut ethnogenesis and one of the clearest examples of a Holocene founder expansion in northern Eurasia.
