Charting the Y-chromosome ancestry of present-day Argentinean Mennonites.
Journal of Human Genetics 61(6):507 (2016)
Old Order Mennonite communities initially arose in Northern Europe (centered in the Netherlands) and derived from the Anabaptist movement of the 16th century. Mennonites migrated to the New World in the early 18th century, first to North America, and more recently to Mesoamerica and South Americ...
Shared language, diverging genetic histories: high-resolution analysis of Y-chromosome variability in Calabrian and Sicilian Arbereshe.
European Journal of Human Genetics 24(4):600 (2016)
The relationship between genetic and linguistic diversification in human populations has been often explored to interpret some specific issues in human history. The Albanian-speaking minorities of Sicily and Southern Italy (Arbereshe) constitute an important portion of the ethnolinguistic variab...
The Greeks in the West: genetic signatures of the Hellenic colonisation in southern Italy and Sicily.
European Journal of Human Genetics 24(3):429 (2016)
Greek colonisation of South Italy and Sicily (Magna Graecia) was a defining event in European cultural history, although the demographic processes and genetic impacts involved have not been systematically investigated. Here, we combine high-resolution surveys of the variability at the uni-parent...
Analysis of Y-chromosome STRs in Chile confirms an extensive introgression of European male lineages in urban populations.
Forensic Science International: Genetics 21:76 (2016)
We analyzed the Y chromosome haplotypes (Yfiler) of 978 non-related Chilean males grouped in five sampling regions (Iquique, Santiago de Chile, Concepción, Temuco and Punta Arenas) covering main geo-political regions. Overall, 803 different haplotypes and 688 singletons were observed. Molecular ...
The Role of Recent Admixture in Forming the Contemporary West Eurasian Genomic Landscape
Current Biology 25(21):2878 (2015)
The Role of Recent Admixture in Forming the Contemporary West Eurasian Genomic Landscape.
Current Biology 25(19):2518 (2015)
Over the past few years, studies of DNA isolated from human fossils and archaeological remains have generated considerable novel insight into the history of our species. Several landmark papers have described the genomes of ancient humans across West Eurasia, demonstrating the presence of large-...
Static and moving frontiers: the genetic landscape of Southern African Bantu-speaking populations.
Molecular Biology and Evolution 32(1):29 (2015)
A consensus on Bantu-speaking populations being genetically similar has emerged in the last few years, but the demographic scenarios associated with their dispersal are still a matter of debate. The frontier model proposed by archeologists postulates different degrees of interaction among incomi...
Ancient human genomes suggest three ancestral populations for present-day Europeans.
Nature 513(7518):409 (2014)
We sequenced the genomes of a ∼7,000-year-old farmer from Germany and eight ∼8,000-year-old hunter-gatherers from Luxembourg and Sweden. We analysed these and other ancient genomes with 2,345 contemporary humans to show that most present-day Europeans derive from at least three highly differenti...
A global analysis of Y-chromosomal haplotype diversity for 23 STR loci.
Forensic Science International: Genetics 12:12 (2014)
In a worldwide collaborative effort, 19,630 Y-chromosomes were sampled from 129 different populations in 51 countries. These chromosomes were typed for 23 short-tandem repeat (STR) loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385ab, DYS437, DYS438, DYS439, DYS448, DYS456, D...
Collaborative EDNAP exercise on the IrisPlex system for DNA-based prediction of human eye colour.
Forensic Science International: Genetics 11:241 (2014)
The IrisPlex system is a DNA-based test system for the prediction of human eye colour from biological samples and consists of a single forensically validated multiplex genotyping assay together with a statistical prediction model that is based on genotypes and phenotypes from thousands of indivi...
Linguistic, geographic and genetic isolation: a collaborative study of Italian populations.
Journal of anthropological sciences = Rivista d... 92:201 (2014)
The animal and plant biodiversity of the Italian territory is known to be one of the richest in the Mediterranean basin and Europe as a whole, but does the genetic diversity of extant human populations show a comparable pattern? According to a number of studies, the genetic structure of Italian ...
Reevaluating a model of gender-biased gene flow among Sub-Saharan Hunter-gatherers and farmers.
Human Biology 85(4):597 (2013)
In a previous study, we proposed a model for genetic admixture between African hunter-gatherers and food producers, in which we integrated demographic and genetic aspects together with ethnographic knowledge (Destro-Bisol et al. 2004b). In that study it was possible to test the model only using ...
Demographic histories, isolation and social factors as determinants of the genetic structure of Alpine linguistic groups.
PLoS ONE 8(12):e81704 (2013)
Great European mountain ranges have acted as barriers to gene flow for resident populations since prehistory and have offered a place for the settlement of small, and sometimes culturally diverse, communities. Therefore, the human groups that have settled in these areas are worth exploring as an...
Reconstructing ancient mitochondrial DNA links between Africa and Europe.
Genome Research 22(5):821 (2012)
Mitochondrial DNA (mtDNA) lineages of macro-haplogroup L (excluding the derived L3 branches M and N) represent the majority of the typical sub-Saharan mtDNA variability. In Europe, these mtDNAs account for <1% of the total but, when analyzed at the level of control region, they show no signals o...
The peopling of Europe and the cautionary tale of Y chromosome lineage R-M269.
Proceedings of the Royal Society B: Biological ... 279(1730):884 (2012)
Recently, the debate on the origins of the major European Y chromosome haplogroup R1b1b2-M269 has reignited, and opinion has moved away from Palaeolithic origins to the notion of a younger Neolithic spread of these chromosomes from the Near East. Here, we address this debate by investigating fre...
Uniparental markers of contemporary Italian population reveals details on its pre-Roman heritage.
PLoS ONE 7(12):e50794 (2012)
According to archaeological records and historical documentation, Italy has been a melting point for populations of different geographical and ethnic matrices. Although Italy has been a favorite subject for numerous population genetic studies, genetic patterns have never been analyzed comprehens...
Allele frequencies of the new European Standard Set (ESS) loci in the Italian population.
Forensic Science International: Genetics 5(5):548 (2011)
Signatures of the preagricultural peopling processes in sub-Saharan Africa as revealed by the phylogeography of early Y chromosome lineages.
Molecular Biology and Evolution 28(9):2603 (2011)
The study of Y chromosome variation has helped reconstruct demographic events associated with the spread of languages, agriculture, and pastoralism in sub-Saharan Africa, but little attention has been given to the early history of the continent. In order to overcome this lack of knowledge, we ca...
Moors and Saracens in Europe: estimating the medieval North African male legacy in southern Europe.
European Journal of Human Genetics 17(6):848 (2009)
To investigate the male genetic legacy of the Arab rule in southern Europe during medieval times, we focused on specific Northwest African haplogroups and identified evolutionary close STR-defined haplotypes in Iberia, Sicily and the Italian peninsula. Our results point to a higher recent Northw...
Mitochondrial haplogroup U5b3: a distant echo of the epipaleolithic in Italy and the legacy of the early Sardinians.
The American Journal of Human Genetics 84(6):814 (2009)
There are extensive data indicating that some glacial refuge zones of southern Europe (Franco-Cantabria, Balkans, and Ukraine) were major genetic sources for the human recolonization of the continent at the beginning of the Holocene. Intriguingly, there is no genetic evidence that the refuge are...
