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...
Samples and data accessibility in research biobanks: an explorative survey.
PeerJ 4:e1613 (2016)
Biobanks, which contain human biological samples and/or data, provide a crucial contribution to the progress of biomedical research. However, the effective and efficient use of biobank resources depends on their accessibility. In fact, making bio-resources promptly accessible to everybody may in...
The Role of Recent Admixture in Forming the Contemporary West Eurasian Genomic Landscape

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-...
Genome-Wide SNP Analysis of Southern African Populations Provides New Insights into the Dispersal of Bantu-Speaking Groups.
Genome Biology and Evolution 7(9):2560 (2015)
The expansion of Bantu-speaking agropastoralist populations had a great impact on the genetic, linguistic, and cultural variation of sub-Saharan Africa. It is generally accepted that Bantu languages originated in an area around the present border between Cameroon and Nigeria approximately 5,000 ...
When data sharing gets close to 100%: what human paleogenetics can teach the open science movement.
PLoS ONE 10(3):e0121409 (2015)
This study analyzes data sharing regarding mitochondrial, Y chromosomal and autosomal polymorphisms in a total of 162 papers on ancient human DNA published between 1988 and 2013. The estimated sharing rate was not far from totality (97.6% ± 2.1%) and substantially higher than observed in other f...
Genetic origins of lactase persistence and the spread of pastoralism in Africa.
The American Journal of Human Genetics 94(4):496 (2014)
In humans, the ability to digest lactose, the sugar in milk, declines after weaning because of decreasing levels of the enzyme lactase-phlorizin hydrolase, encoded by LCT. However, some individuals maintain high enzyme amounts and are able to digest lactose into adulthood (i.e., they have the la...
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 ...
Perspectives on Open Science and scientific data sharing:an interdisciplinary workshop.
Journal of anthropological sciences = Rivista d... 92:179 (2014)
Looking at Open Science and Open Data from a broad perspective. This is the idea behind "Scientific data sharing: an interdisciplinary workshop", an initiative designed to foster dialogue between scholars from different scientific domains which was organized by the Istituto Italiano di Antropolo...
Open data, Science and Society: launching Oasis, the flagship initiative of the Istituto Italiano di Antropologia.

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 ...
Detecting genetic isolation in human populations: a study of European language minorities.
PLoS ONE 8(2):e56371 (2013)
The identification of isolation signatures is fundamental to better understand the genetic structure of human populations and to test the relations between cultural factors and genetic variation. However, with current approaches, it is not possible to distinguish between the consequences of long...
Opening Science to Society, a new initiative of the Istituto Italiano di Antropologia.

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...
Using forensic microsatellites to decipher the genetic structure of linguistic and geographic isolates: A survey in the eastern Italian Alps.
Forensic Science International: Genetics 6(6):827 (2012)
The study of geographically and/or linguistically isolated populations could represent a potential area of interaction between population and forensic genetics. These investigations may be useful to evaluate the suitability of loci which have been selected using forensic criteria for bio-anthrop...
When gender matters: new insights into the relationships between social systems and the genetic structure of human populations.
Molecular Ecology 21(20):4917 (2012)
Due to its important effects on the ecological dynamics and the genetic structure of species, biologists have long been interested in gender-biased dispersal, a condition where one gender is more prone to move from the natal site. More recently, this topic has attracted a great attention from hu...
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...
Online databases for mtDNA and Y chromosome polymorphisms in human populations.
Journal of anthropological sciences = Rivista d... 90:201 (2012)
This study presents an overview of online databases for mtDNA and Y chromosome polymorphisms in human populations. In order to provide readers with information which may help optimize their use, we focus on: (i) type, quantity and source of data contained; (ii) possibilities of downloading and u...
Mine, yours, ours? Sharing data on human genetic variation.
PLoS ONE 7(6):e37552 (2012)
The achievement of a robust, effective and responsible form of data sharing is currently regarded as a priority for biological and bio-medical research. Empirical evaluations of data sharing may be regarded as an indispensable first step in the identification of critical aspects and the developm...
