Resolving the ancestry of Austronesian-speaking populations
Soares, P; Trejaut, JA; Rito, T; Cavadas, B; Hill, C; Eng, KK; Mormina, M; Brandão, A; Fraser, RM; Wang, T-Y; Loo, J-H; Snell, C; Ko, T-M; Amorim, AThere are two very different interpretations of the prehistory of Island Southeast Asia (ISEA), with genetic evidence invoked in support of both. The "out-of-Taiwan" model proposes a major Late Holocene expansion of Neolithic Austronesian speakers from Taiwan. An alternative, proposing that Late Glacial/postglacial sea-level rises triggered largely autochthonous dispersals, accounts for some otherwise enigmatic...
Quantifying the legacy of the Chinese Neolithic on the maternal genetic heritag...
Brandão, A; Eng, KK; Rito, T; Cavadas, B; Bulbeck, D; Gandini, F; Pala, M; Mormina, M; Hudson, B; White, J; Ko, T-M; Saidin, M; Zafarina, ZThere has been a long-standing debate concerning the extent to which the spread of Neolithic ceramics and Malay-Polynesian languages in Island Southeast Asia (ISEA) were coupled to an agriculturally driven demic dispersal out of Taiwan 4000 years ago (4 ka). We previously addressed this question using founder analysis of mitochondrial DNA (mtDNA) control-region sequences to identify major lineage clusters most ...
A substantial prehistoric European ancestry amongst Ashkenazi maternal lineages
Costa, MD; Pereira, JB; Pala, M; Fernandes, V; Olivieri, A; Achilli, A; Perego, UA; Rychkov, S; Naumova, O; Hatina, J; Woodward, SR; Eng, KKThe origins of Ashkenazi Jews remain highly controversial. Like Judaism, mitochondrial DNA is passed along the maternal line. Its variation in the Ashkenazim is highly distinctive, with four major and numerous minor founders. However, due to their rarity in the general population, these founders have been difficult to trace to a source. Here we show that all four major founders, ~40% of Ashkenazi mtDNA variatio...
