Archaic Hominin Populations in Asia before the Arrival of Modern Humans

Abstract

Our traditional scheme during the twentieth century was that Homo erectus had thrived on the vast terrain of eastern Asia since the Early Pleistocene, followed by the appearance of a more advanced but still primitive form of Homo in China during the mid-Middle Pleistocene. Recent discoveries or (re-)recognitions of other archaic hominins, such as Homo floresiensis from an Indonesian island, Neanderthals and the “Denisovans” from southern Siberia, as well as an extremely robust mandible from Taiwan, now open up a different view. By incorporating these latest discoveries, this paper intends to offer a phylogenetic model of diverse archaic Asian hominins distributed from southern Siberia to Southeast Asia and India. On the basis of this new model, I discuss how paleoanthropological data inform the taxonomic identity of the Denisovans and the admixture event with modern humans.
