Our diversity and the Italian Constitution. Do we really need human races?

This paper describes a proposal regarding the presence of the word "race" in the Italian Constitution. Three points are worth of note. Firstly, simply removing the word race from the Constitution is of no real help, since we could miss an indispensable hook for laws concerned with racism. Rather, we should be able to introduce an alternative phrase that: (i) can express the concept of diversity without forgetting all the various aspects of its meaning (biological and cultural, above all); (ii) in no way evokes a hierarchy of values. To make it more effective, the amendment must be accompanied by an explicit statement that race has no meaning for the human species and that any discriminatory view based on such an invalid assumption must therefore be rejected. Secondly, overcoming the old, but still existing, dichotomy between “physical” and “cultural” anthropology, is an absolute necessity in every discussion about the ”human races”. In fact, the term race is also used to stigmatize cultural differences, as if they were the product of different intellectual skills or moral predispositions. Achieving a synthesis between the biological and cultural dimensions of race is a preliminary step to effectively counter the dangerous links between new forms of intolerance and the resurgence of genetic determinism. Thirdly and finally, we should be aware that our commitment must not end simply by signing a document. On the contrary, it must start from there. In our educational and training activities, we must seek to involve wider audiences and provide them with the best tools so they can look at human diversity with no preconceptions. It is important to raise awareness of the need for a change among all those who, for various reasons,are involved in scientific and cultural dissemination

The emerging complexity of open data dynamics: lessons from human evolutionary Genetics & Genomics

In this lecture, I present an overview of data sharing dynamics with a focus on Human Evolutionary Anthropology. I will first discuss three different views on Open data: "Share or die", "I just don'care" and "Tension between secrecy and openness". Then, I will talk about the complexity surrounding open data dynamics in a relatively small research field, Human evolutionary Genetic and Genomics. Thereafter, I will show some results of empirical studies on the data sharing behavior in human genetics and other scientific disciplines, and describe two cases of good practice (Forensic Genetics and Paleogenetics). Finally, I will discuss the implications of arguments and evidence shown here for the future initiatives of the Associazione Italiana per la Scienza Aperta

Anthropologists, Italians and “human races”

This article is part of an international forum on raceand racism published by the Journal of Anthropological Sciences and edited by Alan Goodman of the New Hampshire College (USA). The paper presents an overview of the use and meaning of the term "human race" among Italian scholars, both on the biological and cultural side, in a historical perspective. The theme is also contextualized with respect to political and social current events

Samples and data accessibility in research biobanks. An explorative survey

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 increase the benefits for society. Furthermore, optimizing their use and ensuring their quality will promote scientific creativity and, in general, contribute to the progress of bio-medical research. Although this has become a rather common belief, several laboratories are still secretive and continue to withhold samples and data. In this study, we conducted a questionnairebased survey in order to investigate sample and data accessibility in research biobanks operating all over the world. The survey involved a total of 46 biobanks. Most of them gave permission to access their samples (95.7%) and data (85.4%), but free and unconditioned accessibility seemed not to be common practice. The analysis of the guidelines regarding the accessibility to resources of the biobanks that responded to the survey highlights three issues: (i) the request for applicants to explain what they would like to do with the resources requested; (ii) the role of funding, public or private, in the establishment of fruitful collaborations between biobanks and research labs; (iii) the request of co-authorship in order to give access to their data. These results suggest that economic and academic aspects are involved in determining the extent of sample and data sharing stored in biobanks. As a second step of this study, we investigated the reasons behind the high diversity of requirements to access biobank resources. The analysis of informative answers suggested that the different modalities of resource accessibility seem to be largely influenced by both social context and legislation of the countries where the biobanks operate

From the Alps to the Mediterranean and beyond: genetics, environment, culture and the "impossible beauty" of Italy

Since prehistoric times, Italy has represented a bridge between peoples, genes and cultures. Its peculiar geographical position explains why: it is located in the center of the Mediterranean Sea, flanked by the Balkans and the Hellenic Peninsula to the east, Iberia to the west and surrounded by North Africa to the south and central Europe to the north. This makes Italy of extraordinary interest for the study of some different aspects of human diversity. Here we overview current knowledge regarding the relationships between the structure of the genetic variation of Italian populations and the geographical, ecological and cultural factors that have characterized their evolutionary history. Human presence in Italian territory is deeply rooted in the past. Lithic artifacts produced by the genus Homo and remains of Homo sapiens are among the earliest to have been found on the continent, as shown by the lithic industry of Pirro Nord (between 1.3 and 1.6 Mya) and the dental remains of the "Grotta del Cavallo" (between 45 and 43 Kya). Genetic and genomic studies relating to existing and extinct human groups have shed light on the migrations from Europe, Africa and Asia that created the ancient layers of the genetic structure of today's Italian populations, especially before the Iron Age. The important role of isolation (genetic and cultural) in shaping genetic structure is clearly visible in the patterns of intra- and inter-population diversity observed among Italian ethno-linguistic minorities that settled on the peninsula and on the major islands until the 19th century. Finally, selective pressures have likely driven the distribution of originally adaptive variants and haplotypes that now confer protection or susceptibility to major diseases such as diabetes and cardiovascular disease (in northern Italy) and tuberculosis and leprosy (in the south). What emerges is a picture where the combined effects of migration, isolation and natural selection generated by the interplay of geography, environment and culture have shaped a complex pattern of human diversity that is unique in Europe and which goes hand in hand with today's rich animal and plant biodiversity. In a nutshell, scientific evidence and cultural heritage paint Italy as a place with extremely diverse environments where distant peoples have met since the deep past, bringing and sharing genes and ideas

Mitochondrial, Y-chromosomal and Autosomal Variation in Mbenzele Pygmies from the Central African Republic

In this paper, we carry out a combined analysis of autosomal (ten microsatellites and an Alu insertion), mitochondrial (HVR-1 sequence, 360 nucleotides) and Y-chromosomal (seven microsatellites) variation in the Mbenzele Pygmies from the Central African Republic. This study focuses on two important questions concerning the admixture and origin of African Pygmies. Ethnographic observations suggest a sex-biased gene flow between the Bantus and Pygmies, an issue which could be clarified through genetic analyses may shed light. A study of intrapopulational variation of mtDNA and Y-chromosome produces results in accordance with the hypothesized matrimonial behaviour. In fact, while shared mitochondrial haplotypes belonging to the L1c5 (or L1c1a1 clade) sub-haplogroup provides evidence of a Pygmy-to-Bantu female biased gene flow, a male biased gene flow from Bantu to Pygmies is supported by the distribution of the Y-chromosomes bearing M2 mutation. The second part of our study regards the question of the genetic relationships between Western and Eastern Pygmies. Our results favour the pre-Bantu hypothesis which suggests that the two Pygmy groups separated in ancient times (at least 18,000 years ago), whereas they do not support the recent divergence and differential admixture hypothesis which posits their separation as a consequence of the Bantu expansion (2,000–3,000 years ago)

When data sharing gets close to 100%. What human paleogenetics can teach the open science movement

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 fields of genetic research (evolutionary, medical and forensic genetics). Both a questionnaire-based survey and the examination of Journals’ editorial policies suggest that this high sharing rate cannot be simply explained by the need to comply with stakeholders requests. Most data were made available through body text, but the use of primary databases increased in coincidence with the introduction of complete mitochondrial and next-generation sequencing methods. Our study highlights three important aspects. First, our results imply that researchers’ awareness of the importance of openness and transparency for scientific progress may complement stakeholders’ policies in achieving very high sharing rates. Second, widespread data sharing does not necessarily coincide with a prevalent use of practices which maximize data findability, accessibility, useability and preservation. A detailed look at the different ways in which data are released can be very useful to detect failures to adopt the best sharing modalities and understand how to correct them. Third and finally, the case of human paleogenetics tells us that a widespread awareness of the importance of Open Science may be important to build reliable scientific practices even in the presence of complex experimental challenges
