Spatially explicit analysis reveals complex human genetic gradients in the Iber...
Pimenta, J; Lopes, AM; Carracedo, A; Arenas, M; Amorim, A; Comas, DThe Iberian Peninsula is a well-delimited geographic region with a rich and complex human history. However, the causes of its genetic structure and past migratory dynamics are not yet fully understood. In order to shed light on them, here we evaluated the gene flow and genetic structure throughout the Iberian Peninsula with spatially explicit modelling applied to a georeferenced genetic dataset composed of geno...
European Roma groups show complex West Eurasian admixture footprints and a comm...
Font-Porterias, N; Arauna, LR; Poveda, A; Bianco, E; Rebato, E; Prata, MJ; Calafell, F; Comas, DThe Roma population is the largest transnational ethnic minority in Europe, characterized by a linguistic, cultural and historical heterogeneity. Comparative linguistics and genetic studies have placed the origin of European Roma in the Northwest of India. After their migration across Persia, they entered into the Balkan Peninsula, from where they spread into Europe, arriving in the Iberian Peninsula in the 15t...
Evaluating the Neolithic Expansion at Both Shores of the Mediterranean Sea
Pimenta, J; Lopes, AM; Comas, D; Amorim, A; Arenas, MDuring the Neolithic, human populations underwent cultural and technological developments that led to an agricultural revolution. Although the population genetics and evolution of European Neolithic populations have been extensively studied, little is known regarding the Neolithic expansion in North Africa with respect to Europe. One could expect that the different environmental and geological conditions at bot...
The genome-wide structure of the Jewish people
Behar, DM; Yunusbayev, B; Metspalu, M; Metspalu, E; Rosset, S; Parik, J; Rootsi, S; Chaubey, G; Kutuev, I; Yudkovsky, G; Khusnutdinova, EKContemporary Jews comprise an aggregate of ethno-religious communities whose worldwide members identify with each other through various shared religious, historical and cultural traditions. Historical evidence suggests common origins in the Middle East, followed by migrations leading to the establishment of communities of Jews in Europe, Africa and Asia, in what is termed the Jewish Diaspora. This complex demog...
The dawn of human matrilineal diversity
Behar, DM; Villems, R; Soodyall, H; Blue-Smith, J; Pereira, L; Metspalu, E; Scozzari, R; Makkan, H; Tzur, S; Comas, D; Bertranpetit, JThe quest to explain demographic history during the early part of human evolution has been limited because of the scarce paleoanthropological record from the Middle Stone Age. To shed light on the structure of the mitochondrial DNA (mtDNA) phylogeny at the dawn of Homo sapiens, we constructed a matrilineal tree composed of 624 complete mtDNA genomes from sub-Saharan Hg L lineages. We paid particular attention t...
