Review of recent papers on East Asia, quite relevant these days: Human Genetics: Busy Subway Networks in Remote Oceania? by Anders Bergström & Chris Tyler-Smith, Current Biology (2018) 28.
Interesting excerpts (emphasis mine):
Ancient DNA is transforming our understanding of the human past by forcing geneticists to confront its real complexity . Historians and archaeologists have long known that the development of human societies was complex and often haphazard, but geneticists have persistently tried to explain present-day patterns of genetic variation using simple models.
Early genetic analyses of present-day populations revealed a mix of Asian (Taiwanese) and Papuan (New

New article (behind paywall) Language continuity despite population replacement in Remote Oceania, by Posth et al., Nat. Ecol. Evol. (2018).
Recent genomic analyses show that the earliest peoples reaching Remote Oceania—associated with Austronesian-speaking Lapita culture—were almost completely East Asian, without detectable Papuan ancestry. However, Papuan-related genetic ancestry is found across present-day Pacific populations, indicating that peoples from Near Oceania have played a significant, but largely unknown, ancestral role. Here, new genome-wide data from 19 ancient South Pacific individuals provide direct evidence of a so-far undescribed Papuan expansion into Remote Oceania starting ~2,500 yr BP, far earlier than previously
