Along the rocky coves and shell-rich terraces of eastern Taiwan, the Hanben horizon emerges in the archaeological record between roughly 1 and 800 CE. Excavations at the Blihun locality within the Hanben complex reveal dense shell middens, pottery with distinctive cord-marked and impressed styles, ground stone tools, and personal ornaments carved from shell and bone. These material signatures situate Hanben within the broader tapestry of Iron Age Taiwan, yet the term 'Iron Age' here primarily indexes a regional chronology rather than ubiquitous metal use; iron artifacts are uncommon and often imported.
Hanben communities participated in coastal networks that extended across the northern Philippines and the archipelagic margins of Southeast Asia. Obsidian and other exotic lithics hint at long-distance exchange, while local craft traditions retained continuity with earlier Neolithic coastal sites. Archaeological data indicates a persistent maritime orientation: sites are often located on raised beaches or river mouths, where fishing and shellfish gathering left visible deposits.
Genetically, ancient DNA from Hanben individuals provides a new lens on origins. The observed maternal and paternal lineages align broadly with East and Southeast Asian ancestries, supporting archaeological interpretations that link Hanben peoples to Austronesian-speaking coastal traditions. However, the full story of population formation is complex: demographic shifts, episodic contacts, and local continuity all likely contributed. Limited preservation and the uneven spatial sampling of sites mean that archaeological and genetic narratives should be held as provisional and open to refinement.
