Denisovans from southwestern China and their subsistence strategies

Abstract

Growing fossil and genomic evidence has substantially advanced our understanding of Denisovans’ evolutionary history, yet their technological behaviours and subsistence strategies remain poorly documented. Here we present a comprehensive analysis of hominin fossils and associated archaeological remains from Bianfu Cave, Yunnan Province, southwestern China. The hominin fossils are dated to about 167–134 thousand years ago (ka), whereas the cultural sequence spanned from about 190?ka to 70?ka, representing one of the longest cultural records most parsimoniously attributed to Denisovans—identified through enamel–dentine junction morphology and palaeoproteomic analyses. The new fossils include four teeth that expand the known dental variation of this group, two cranial fragments and a radius. Faunal and pollen records indicate a conifer-dominated forest or forest-steppe environment across Marine Isotope Stages 6 to 4. The inhabitants of Bianfu Cave practised specialized hunting of medium- to large-bodied prey and used a technological strategy characterized by expedient core reduction and tool production, alongside pervasive use of unmodified bones. This pattern suggests an adaptive system prioritizing the exploitation of object affordance over intensive tool manufacture. Bianfu Cave provides unprecedented insights into Denisovan biology, behaviour and ecology in eastern Asia and points to a substantial genetic and cultural legacy in later populations in Southeast Asia and Oceania.
