    Published 2020-07-01
    “…Based on simulations under the dual structure model (a specific demography for the Japanese) and phylogenetic analysis with ancient DNA, the T allele at rs2294008 might have had high frequency in the Jomon people (one of the ancestral populations of the modern Japanese); this may explain the high T allele frequency in the extant Japanese.…”

    The genetic structure of the British populations and their surnames by Bodmer, W, Winney, B

    Published 2016
    “…<p> Until large-scale ancient DNA studies of archaeological samples become practical, genetic studies of current human populations, with a few caveats, are a productive way to investigate past movements of peoples (Røyrvik 2010). …”

    Using commensals as proxies for historical inference in the Indian ocean: genetic and zooarchaeological perspectives by Eager, H, Heidi Eager

    Published 2014
    “…Closer to the origins of the three species (the Indian subcontinent in all cases), range expansions in Eurasia and nearby islands relate to early to mid Holocene human populations, but also with signals of later secondary colonisations. Through ancient DNA studies I found genetic continuity between temporally separated populations of black rats suggesting population persistence, and high levels of diversity in Songo Mnara, a Swahili stonetown in Tanzania. …”

    Island biogeography revisited: museomics reveals affinities of shelf island birds determined by bathymetry and paleo-rivers, not by distance to mainland by Kritika M. Garg, Balaji Chattopadhyay, Emilie Cros, Suzanne Tomassi, Suzan Benedick, David P. Edwards, Frank E. Rheindt

    Published 2022
    “…A key question is whether these predictions follow at a population-genomic level. Using rigorous ancient-DNA protocols, we retrieved approximately 1,000 genomic markers from approximately 100 historic specimens of two Southeast Asian songbird complexes from across the Sunda Shelf archipelago collected 1893–1957. …”
