In the last decade there has been a wealth of new or re-dated evidence in Southeast Asia that suggests that modern humans dispersed across the region en route to Australasia much earlier than previously accepted. This so-called long chronology for human dispersal has been met with some resistance based on questions of provenance, dating applications, stratigraphic integrity and direct association between material being dated and the human evidence. In fact, in some cases there have been claims for this evidence to be disregarded. But are these claims valid, and can we afford to throw out evidence when there is such a dearth of palaeoanthropology from this region? In this presentation, we will explore the evidence from three key sites; Lida Ajer, Tam Pa Ling and Punung that support the long chronology and reassess whether this evidence is still robust in light of new methods and newly discovered sites. The work at Tam Pa Ling is ongoing with new discoveries associated with each year of excavation, the site of Punung has been recently reassessed, while the sedimentology and dating of Lida Ajer cave has been revisited, and all this new evidence will be presented in an effort to contribute to this ongoing debate.
