Human diet in Mantua (Northern Italy)
The Copper to Middle Bronze Ages are particularly significant times in Italian Protohistory, as they were marked by major dietary, social, and technological transformations. Stable isotope analysis has become a key tool in reconstructing past human diets. Although its application has expanded across the Italian Peninsula over the past decade, data for the Copper Age in northern Italy remain limited, and geographic coverage is still uneven. This s…
Romito 9
During recent excavations at Grotta del Romito (Papasidero, northern Calabria, Italy), a new Upper Palaeolithic burial—designated Romito 9—was identified. The burial pit had been partially disturbed ab antiquo, resulting in an altered depositional context. The burial pertains to a female individual, approximately 11–12 years of age, and is associated with an archaeological layer dated to 16,129 ± 100 uncal BP (19,809–19,157 cal BP, 2σ), correspon…
Family History in the Iberian Peninsula during Chalcolithic and Bronze Age
Throughout history, it has been observed that human populations have buried the deceased members of their communities following different patterns. During the Copper Age and the Bronze Age—periods on which this study focuses—in the northern sub-plateau of the Iberian Peninsula, we identified different patterns of multiple or collective burial. This work analyzes a total of 58 individuals buried in different multiple or collective graves, to inves…

Archaeobotanical record from dental calculus of a Roman individual affected by bilateral temporo-mandibular joint ankylosis
Dental calculus and isotopes reveal information about ancient diet of Boccone del Povero community (1st-2nd century CE, Latium, central Italy)
How Mitochondrial DNA Can Write Pre-History
The chronological period from the beginning of the Chalcolithic Age to the end of the Bronze Age on the Iberian northern sub-plateau of the Iberic Peninsula involves interesting social and cultural phenomena, such as the appearance of the Bell Beaker and, later, the Cogotas I cultures. This work constructs a genetic characterisation of the maternal lineages of the human population that lived on the northern sub-plateau between 5000 and 3000 years…
Isotopic reconstruction of the subsistence strategy for a Central Italian Bronze Age community (Pastena cave, 2nd millennium BCE)
The Pastena cave is located in central Italy, and its best-preserved sector is Grotticella W2, which is dated radiometrically to the Early-Middle Bronze Age. The aim of this paper is to explore human diet, animal husbandry, and plant management, analysing the findings there discovered. Carbon and nitrogen stable isotope analysis was carried out on 40 charred seeds, six faunal remains, and four human individuals, investigating the whole bio-archae…

Dietary and Weaning Habits of the Roman Community of Quarto Cappello del Prete (Rome, 1st-3 rd Century CE)
This paper aims to provide the isotopic characterization of the diet consumed by people buried in a graveyard of the Imperial Rome Suburbium (1st–3rd centuries CE), where numerous children were buried. A sample of 50 human remains from Quarto Cappello del Prete was selected for carbon and nitrogen stable isotope analysis. Published data related to coeval faunal remains set the baseline of the diet. The results for humans were integrated with prev…
Food at the heart of the Empire
This paper aims to provide a broad diet reconstruction for people buried in archaeologically defined contexts in Rome (first to third centuries CE), in order to combine archaeological and biological evidence focusing on dietary preferences in Imperial Rome. A sample of 214 human bones recovered from 6 funerary contexts was selected for carbon and nitrogen stable isotope analysis. The baseline for the terrestrial protein component of the diet was …
The edge of the Empire
This paper aims to define the dietary profile of the population of early medieval Rome (fifth-eleventh centuries CE) by carbon and nitrogen stable isotope analysis. This period was characterized by deep changes in the city's economic, demographic, and social patterns, probably affecting its inhabitants' nutritional habits. Carbon and nitrogen stable isotope analysis of bone collagen was used to detect the nutritional profile of 110 humans from si…

Stable isotopic evidence for diet at the Imperial Roman coastal site of Velia (1st and 2nd Centuries AD) in Southern Italy
Here we report on a stable isotope palaeodietary study of a Imperial Roman population interred near the port of Velia in Southern Italy during the 1st and 2nd centuries AD. Carbon and nitrogen stable isotope analyses were performed on collagen extracted from 117 adult humans as well as a range of fauna to reconstruct individual dietary histories. For the majority of individuals, we found that stable isotope data were consistent with a diet high i…
Genetic analysis of early holocene skeletal remains from Alaska and its implications for the settlement of the Americas
Mitochondrial and Y‐chromosome DNA were analyzed from 10,300‐year‐old human remains excavated from On Your Knees Cave on Prince of Wales Island, Alaska (Site 49‐PET‐408). This individual's mitochondrial DNA (mtDNA) represents the founder haplotype of an additional subhaplogroup of haplogroup D that was brought to the Americas, demonstrating that widely held assumptions about the genetic composition of the earliest Americans are incorrect. The amo…
Stable isotope analysis of Late Upper Palaeolithic human and faunal remains from Grotta del Romito (Cosenza), Italy
Examining dietary variability of the earliest farmers of South‐Eastern Italy
Stable isotope analysis of human remains has been used to address long‐standing debates regarding the speed and degree to which the introduction of farming transformed diet. In Europe, this debate has centered on northern and Atlantic regions with much less attention devoted to the arrival of farming across the Mediterranean. This study presents carbon and nitrogen stable isotope analyses of collagen from 19 human and 37 faunal remains from eight…

Genetic structure of the population of Sicily
Genetic heterogeneity within Sicily was investigated on the basis of ACP1, ADA, ESD, GLO1, PGD, PGM1, PGM2, SODA, ABO, and MN gene frequencies, and compared to those of other regions of Italy for which these same loci have been examined. Correspondence analysis revealed no differences within the island, at least at the provincial level, but showed genetic differentiation among Italian regions, distinctly clustering northern, central, and southern…
Palaeobiology of the Medieval Population of Albano (Rome, Italy)
Recent years have seen increased interest in skeletal populations from the Imperial Roman Age in Italy, but much less is known about diet and standards of living in the subsequent medieval period. To fill this gap, we conducted a morphological analysis of human remains from Albano, an Italian town near Rome, as well as a stable isotope analysis of bone collagen to reconstruct diet. The sample was recovered from a Medieval cemetery (1040-1220 cal.…
Palaeodiet reconstruction in a woman with probable celiac disease
Stable isotope analysis in the reconstruction of human palaeodiets can yield clues to early human subsistence strategies, origins and history of farming and pastoralist societies, and intra‐ and intergroup social differentiation. In the last 10 years, the method has been extended to the pathological investigation. Stable isotope analysis to better understand a diet‐related disease: celiac disease in ancient human bones was carried out. To do this…

Analysis of the region V mitochondrial marker in two Black communities of Ecuador, and in their parental populations
Deep into the roots of the Libyan Tuareg
Recent genetic studies of the Tuareg have begun to uncover the origin of this semi‐nomadic northwest African people and their relationship with African populations. For centuries they were caravan traders plying the trade routes between the Mediterranean coast and south‐Saharan Africa. Their origin most likely coincides with the fall of the Garamantes who inhabited the Fezzan (Libya) between the 1st millennium BC and the 5th century AD. In this s…

This paper reports an exhaustive and updated compilation of phenotype and allele frequency data for phosphoglucomutase locus 1 (PGM1), obtained with an analytical isoelectric focusing technique, in human populations. The analysis of the PGM1 allele frequency distributions within and among the major human groups together with the degree of diversification evaluated by Wright's F st , computed per allele and averaged over alleles, are also presente…
Survey of seven plasma protein polymorphisms in the Amhara and Oromo populations of Ethiopia
The Ethiopian population is very difficult to specify due to a very high degree of intermixing among different peoples. The two groups of the present study, the Amhara and Oromo, constitute 38% and 35% of the population, respectively. In order to investigate the genetic composition of the Amhara and Oromo, genetic polymorphisms of seven plasma proteins (F13A, F13B, ORM1, AHSG, C6, C7, and APOC2), already identified as useful anthropological marke…
The Cayapa Indians of Ecuador
The Cayapa Indians are a population of 3600 individuals living in Ecuador, along the Cayapas River and its tributaries. They are thought to have migrated from the Andes, north of Quito, and settled in the Cayapas area five centuries ago as a consequence of Inca expansion and of the Spanish conquest. In order to study the genetic structure of the Cayapa and their relationships with other native American peoples, and to enquire on the possibility o…
Genetic relationships among the Native American populations
Red cell antigen data were used to investigate the genetic relationship among the Native American populations and their affinities with Siberian and Eastern Asian populations. Correspondence analysis showed a clear subdivision of all the Native American populations into three clear-cut clusters corresponding to the three linguistic families (identified by Greenberg)--Amerind, Na-Dene and Eskimo-Aleut. This result, as well as the close genetic res…

New Data on the World Distribution of Paraoxonase ( PON1 Gln 192--Arg) Gene Frequencies
The physiological role of human paraoxonase (PON), a serum enzyme that hydrolyzes organophosphate insecticides and nerve agents, is not clear. Of the three genes in the paraoxonase gene family, PON1 shows a polymorphism, Gln 192 --> Arg, governed by two common alleles named *Q and *R. These determine two different isoforms associated, respectively, with lower and higher activity towards paraoxon, a toxic metabolic product of the insecticide parat…

Beringian Standstill and Spread of Native American Founders
Native Americans derive from a small number of Asian founders who likely arrived to the Americas via Beringia. However, additional details about the initial colonization of the Americas remain unclear. To investigate the pioneering phase in the Americas we analyzed a total of 623 complete mtDNAs from the Americas and Asia, including 20 new complete mtDNAs from the Americas and seven from Asia. This sequence data was used to direct high-resolution…
