The fifth annual symposium of the DFG Center for Advanced Studies at the University of Tübingen, Germany will be held from the 12th to 14th of December 2019. The symposium, entitled “Maritime Connections” will focus on the (pre)history of Island Southeast Asia, Australia, and the Pacific. Research in this part of the world has intensified over the last years, with archaeological and paleontological findings pointing to previously unknown hominin populations and new species, as well as evidence for modern human occupation in the region at time periods earlier than previously documented. In addition, the region remains as one of the most linguistically and ecologically diverse in the world, with biological and cultural connections by sea that likely extend into deep, prehistoric time periods. As such, the symposium aims to consolidate the current knowledge of human occupation in the region and to discuss the mechanisms and dynamics leading to the diversity of languages and peoples living there today.
