Qihe Epipaleolithic of Fujian

Perched within the rugged subtropical landscape of southern Fujian, Qihe Cave (Zhangping) preserves a whisper of human activity from the late Pleistocene to the early Holocene. Radiocarbon-calibrated material associated with the Epipaleolithic layer falls between 9798 and 9407 BCE, placing this site among the earliest documented occupations in this coastal-shelf zone of southeast China. Archaeological data indicates episodic occupation by small, mobile forager groups who exploited a mosaic of riverine, forest, and nearshore resources.

The singular ancient genome recovered from Qihe provides a genetic snapshot rather than a full portrait. While material culture from Epipaleolithic China often shows regional variability in stone-tool traditions and site-use, Qihe's deposits contribute to a broader pattern of early human settlement along China’s southeastern margins. Limited evidence suggests these groups adapted to shifting sea levels and seasonal resource pulses during the transition from the Pleistocene into the Holocene.

Because the genetic dataset from Qihe consists of one individual, archaeological and environmental context carries heightened importance: stratigraphy, faunal remains, and lithic assemblages remain essential to interpret how this person lived and moved across the landscape. Together, material and molecular traces hint at a deep-time presence of human groups who would ultimately contribute to the genetic tapestry of later East Asian populations, but the picture is necessarily incomplete and provisional.

Genetic data from Qihe currently derive from a single individual dated to between 9798 and 9407 BCE. The mitochondrial genome is assigned to macro-haplogroup R. Haplogroup R is a widespread maternal lineage with deep roots across Eurasia and known subclades in East Asia; however, the detection of R in one ancient individual cannot by itself resolve population history or affinity. No Y-chromosome data are reported for this sample.

Because the sample count is one, all genetic interpretations must be treated as preliminary. The presence of mtDNA R at Qihe is compatible with multiple scenarios: local continuity of maternal lineages, gene flow along coastal corridors, or retention of an older regional maternal lineage. Ancient DNA from neighboring sites and later periods will be essential to test whether the Qihe individual reflects a persistent local population or an episode of movement and admixture.

Genomic comparisons—when more data are available—can place Qihe within broader patterns observed in East Asia, such as differentiation between inland and coastal groups, and the complex interplay of hunter-gatherer and incoming farmer ancestries in later millennia. For now, the genetic signal at Qihe is a single, evocative thread that underscores the need for further sampling and cautious synthesis of archaeology and DNA.
