Three published genomes from Miaozigou (sample count = 3) provide a preliminary window into biological ancestry during the Middle Neolithic. Two of the three male individuals carry Y-chromosome haplogroup C; mitochondrial haplogroups observed are A14, C, and D (one each). Haplogroup C is widely associated with northern and northeastern Asian paternal lineages, while mtDNA lineages A, C, and D are common across East Asia and Siberia and appear in multiple ancient and modern northern populations.
These genetic signatures align with an expectation of deep East Eurasian ancestry in northeastern China during the Neolithic, supporting archaeological impressions of local continuity rather than wholesale replacement by distant groups. However, with only three genomes, any inference about demographic processes—migration, admixture, or sex-biased continuity—must be cautious. Limited sample size makes it impossible to determine population structure, temporal changes, or the frequency of these haplogroups in the broader Miaozigou population.
Integration of genome-wide autosomal data, greater spatial sampling across Miaozigou-phase sites, and comparison with contemporaneous populations across northern China and Siberia would be required to resolve questions about mobility, kinship, and the genetic landscape of early northeastern agriculturalists.
