Huatuyan Cave: Ming-era Mothers of Guangxi

The Huatuyan assemblage is rooted in the limestone hills of Lihu Yaozu Town, Huatu Village, within modern Hechi City, Nandan County. Archaeological data indicates that the cave was used for human deposition or burial during a period spanning the late Ming dynasty into the early Qing (c. 1400–1700 CE). The stratigraphy and associated organic remains suggest episodic use rather than continuous habitation.

Culturally, this period in Guangxi was one of agrarian communities and local ethnic diversity; records and material culture from nearby sites hint at interactions among Han migrants, Yao communities, and other southern populations. The Huatuyan human remains appear in contexts that align with small-scale village mortuary practices rather than elite tomb architecture of coastal plains.

Limited evidence suggests that the people represented at Huatuyan were part of long-standing local populations in southern China, with deep continuity of maternal lineages typical of East and Southeast Asia. Given the small sample count (n=8) and incomplete contextual data, any model of population movement or demographic change must remain provisional. Future excavation and direct radiocarbon dating of individual remains will refine chronologies and clarify relationships with regional historical events such as Ming-era migrations and Qing consolidation.

Ancient DNA analysis of eight individuals from Huatuyan Cave produced maternally inherited mitochondrial haplogroups indicative of East and Southeast Asian affinities. Observed mtDNA lineages include haplogroup D (2 individuals), F (1), N (1), M (1) and R (1). These haplogroups are common across southern China, mainland Southeast Asia, and among many modern Sino-Tibetan and Austroasiatic-speaking populations.

No consistent Y-DNA signal is reported for this dataset, and limited male-specific markers or preservation may have prevented paternal lineage characterization. Because the total sampled individuals number only eight, and mtDNA represents only maternal ancestry, conclusions about the broader population must remain tentative. Small sample sizes can overrepresent particular lineages and obscure diversity.

Nonetheless, the mitochondrial profile aligns with archaeological expectations for Guangxi: continuity of regional maternal lineages through the late first millennium into the historic era, and genetic connections that mirror known cultural networks linking southern China and Southeast Asia. Future sampling, genome-wide data, and direct radiocarbon dating of individuals will be essential to test hypotheses about migration, admixture, and social structure.
