TL;DR: Ancient DNA analysis of archaeological cat remains shows cats dispersed along trade routes from the Neolithic era onwards, while its gene pool shows admixture from multiple geographical sources and that the tabby allele originated in the Middle Ages.
Journal ArticleDOI
A New High-Throughput Approach to Genotype Ancient Human Gastrointestinal Parasites.
Nathalie M. L. Côté,Nathalie M. L. Côté,Julien Daligault,Mélanie Pruvost,E. Andrew Bennett,Olivier Gorgé,Silvia Guimaraes,Nicolas Capelli,Matthieu Le Bailly,Eva-Maria Geigl,Thierry Grange +10 more
TL;DR: The study of twenty-five 100 to 7,200 year-old archeological samples proved a PCR-based approach coupled with next-generation sequencing to perform precise taxonomic identification of parasitic helminths directly from archeological sediments to be a powerful, reliable and efficient approach for species determination.
Journal ArticleDOI
Past climate changes, population dynamics and the origin of Bison in Europe
Diyendo Massilani,Silvia Guimaraes,Jean-Philip Brugal,Jean-Philip Brugal,E. Andrew Bennett,Małgorzata Tokarska,Rose-Marie Arbogast,Gennady F. Baryshnikov,G. G. Boeskorov,Jean-Christophe Castel,Sergey Davydov,Stéphane Madelaine,Olivier Putelat,Natalia N. Spasskaya,Hans-Peter Uerpmann,Thierry Grange,Eva-Maria Geigl +16 more
TL;DR: The paleogenetic analysis of bison remains from the last 50,000 years reveals the influence of climate changes on the dynamics of the various bison populations in Europe, only one of which survived into the Holocene, where it experienced severe reductions in its genetic diversity.
Journal ArticleDOI
Genealogical Discontinuities among Etruscan, Medieval, and Contemporary Tuscans
Silvia Guimaraes,Silvia Ghirotto,Andrea Benazzo,Lucio Milani,Martina Lari,Elena Pilli,Elena Pecchioli,Francesco Mallegni,Barbara Lippi,Francesca Bertoldi,Sauro Gelichi,Antonella Casoli,Elise M. S. Belle,David Caramelli,Guido Barbujani +14 more
TL;DR: Genetic continuity between ancient and modern populations of the same area does not seem a safe general assumption, but rather a hypothesis that, when possible, should be tested using ancient DNA analysis.
Journal ArticleDOI
Taming the late Quaternary phylogeography of the Eurasiatic wild ass through ancient and modern DNA
E. Andrew Bennett,Sophie Champlot,Joris Peters,Benjamin S. Arbuckle,Silvia Guimaraes,Mélanie Pruvost,Shirli Bar-David,Simon J. M. Davis,Mathieu Gautier,Petra Kaczensky,Ralph Kuehn,Marjan Mashkour,Arturo Morales-Muñiz,Erich Pucher,Jean-Francois Tournepiche,Hans-Peter Uerpmann,Adrian Bălăşescu,Mietje Germonpré,Can Yümni GüNDEM,Mahmoud-Reza Hemami,Pierre-Elie Moulle,Aliye Ötzan,Margarete Uerpmann,Chris Walzer,Thierry Grange,Eva-Maria Geigl +25 more
TL;DR: This study places the extinct European wild ass, E. hydruntinus, into its phylogenetic context within the Asiatic wild asses and reveals recent mitochondrial introgression between populations currently regarded as separate species.
