Reconciling evidence from ancient and contemporary genomes: a major source for ...
Pereira, JB; Costa, MD; Vieira, D; Pala, M; Bamford, L; Harich, N; Cherni, L; Alshamali, F; Hatina, J; Rychkov, S; Stefanescu, G; King, T; Torroni, AImportant gaps remain in our understanding of the spread of farming into Europe, due partly to apparent contradictions between studies of contemporary genetic variation and ancient DNA. It seems clear that farming was introduced into central, northern, and eastern Europe from the south by pioneer colonization. It is often argued that these dispersals originated in the Near East, where the potential source genet...
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...
Mitochondrial DNA signals of Late Glacial recolonization of Europe from Near Ea...
Pala, M; Olivieri, A; Achilli, A; Accetturo, M; Metspalu, E; Reidla, M; Tamm, E; Karmin, M; Reisberg, T; Hooshiar Kashani, B; Perego, UA; Carossa, VHuman populations, along with those of many other species, are thought to have contracted into a number of refuge areas at the height of the last Ice Age. European populations are believed to be, to a large extent, the descendants of the inhabitants of these refugia, and some extant mtDNA lineages can be traced to refugia in Franco-Cantabria (haplogroups H1, H3, V, and U5b1), the Italian Peninsula (U5b3), and t...
