Journal ArticleDOI
Nuclear and Mitochondrial DNA Analysis of a 2,000-year-old Necropolis in the Egyin Gol Valley of Mongolia
TL;DR: This is the first study using biparental, paternal, and maternal genetic systems to reconstruct partial genealogies in a protohistoric necropolis and showed close relationships between several specimens.
Journal ArticleDOI
Ancient DNA reveals male diffusion through the Neolithic Mediterranean route
Marie Lacan,Christine Keyser,François-Xavier Ricaut,Nicolas Brucato,Francis Duranthon,Jean Guilaine,Eric Crubézy,Bertrand Ludes +7 more
TL;DR: The Y-haplotype lineages characterized and the study of their current repartition in European populations confirm a greater influence of the Mediterranean than the Central European route in the peopling of southern Europe during the Neolithic transition.
Journal ArticleDOI
Ancient DNA suggests the leading role played by men in the Neolithic dissemination
Marie Lacan,Christine Keyser,François-Xavier Ricaut,Nicolas Brucato,Josep Tarrús,Àngel Bosch,Jean Guilaine,Eric Crubézy,Bertrand Ludes +8 more
TL;DR: DNA extracted from human remains excavated in a Spanish funeral cave is studied to obtain information on the early Neolithic funeral practices and on the biogeographical origin of the inhumed individuals, indicating a surprising temporal genetic homogeneity in these groups.
Journal ArticleDOI
Results of a collaborative study of the EDNAP group regarding mitochondrial DNA heteroplasmy and segregation in hair shafts.
Gillian Tully,S.M Barritt,Klaus Bender,E Brignon,Cristian Capelli,N Dimo-Simonin,C. Eichmann,C.M Ernst,C Lambert,Maria Victoria Lareu,Bertrand Ludes,B. Mevåg,Walther Parson,Heidi Pfeiffer,A. Salas,Peter M. Schneider,E Staalstrom +16 more
TL;DR: The results showed that the C/T point heteroplasmy observed in blood and buccal cells at position 16234 segregated differentially between hairs, such that some hairs showed only C, others only T and the remainder, C/Ts at varying ratios, which has implications for forensic mtDNA typing.
Journal ArticleDOI
STR-genotyping from human medieval tooth and bone samples
TL;DR: The DNA present in these ancient remains appeared very degraded, but nevertheless, better conserved in tooth than in bone samples, and it was showed that the DNA extracted from ancient dental pulp was not exempt from polymerase chain reaction (PCR) inhibitors, which could result from extreme DNA fragmentation.
