Fujian Coastal Neolithic Echoes

The Qihedong individual from the Wuyi‑Nanling hills of Zhangping, Fujian, dated to 6474–6401 BCE, comes from an early coastal strand of the Neolithic in southeast China. Archaeological data indicates people in this zone were exploiting nearshore resources and occupying sheltered river mouths and terraces along the modern coastline. Limited evidence suggests these communities formed part of a broader arc of early coastal settlement that extended into what archaeologists group as Early Neolithic Coastal Southeast Asia.

Palaeoenvironmental reconstructions imply a dynamic shoreline in the mid‑Holocene: rising sea levels and shifting estuaries created rich intertidal habitats. In cinematic terms, these early fishermen and foragers lived where land met sea, harvesting shellfish, fish, and riverine plants while experimenting with domesticated crops in nearby lowlands. The single genetic sample from Qihedong adds an extra dimension: rather than replacing archaeology, the genome is woven into it, offering a human face to the artifacts and middens. However, because only one genome is available, narrative threads about migration routes, origins, and demographic expansion must be treated as provisional rather than definitive.

Genetic evidence from Qihedong is tantalizing but extremely limited: one individual dated to 6474–6401 BCE with mitochondrial haplogroup R. Haplogroup R is an ancient maternal lineage with broad Eurasian distribution; its presence here indicates that deep maternal lineages common across western and eastern Eurasia were also part of the genetic tapestry in coastal China during the early Neolithic. Because the dataset is a single sample (n=1), population‑level claims—about continuity, admixture, or specific migration routes—remain speculative and should be framed as hypotheses to be tested.

No robust Y‑chromosome data is reported for this individual, so paternal lineages remain unknown. Archaeogenetic comparisons with better‑sampled Early Neolithic coastal populations in Southeast Asia and inland Neolithic groups may in the future reveal whether coastal Fujianers formed a distinct genetic cluster or represented a zone of mixing between inland hunter‑gatherers, northern Neolithic farmers, and maritime migrants. Preliminary signals could point toward coastal corridors facilitating gene flow, but only additional genomic sampling (multiple individuals across sites and times) can clarify demographic processes, admixture dates, and the ancestral proportions that shaped later populations in East and Southeast Asia.
