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 sites in the Apulia and Marche regions of south-eastern and central Italy, dating to the early phases of agricultural adoption during the first half of the 6th Millennium BC. Where collagen preservation permitted, sulfur stable isotope analysis was also performed. Overall, there was significant isotopic variation between the different geographic regions, although there was also considerable uncertainty in interpreting these data, especially given heterogeneous isotope values for fauna from site to site. By considering isotope data from each region separately, it was noticeable that the degree of carbon isotope enrichment in humans compared to fauna was higher for individuals buried near the coast, consistent with increased marine consumption. Coastal individuals also had higher sulfur isotope values. Nitrogen isotope values were very variable between individuals and regions and, in some cases, were consistent with very high plant food consumption. Overall, early "farmers" in south-east and central Italy consumed a wide range of foods, including marine, and had much more variable stable isotope values than those observed in central and northern Europe during this period, perhaps indicating a different mode for agricultural adoption.

There is a strong relation between people's structured identities and their chemical biographies: these can reflect the way individuals choose to reside and/or move. The strontium isotope ratio (87Sr/86Sr) of skeletal remains is considered a useful proxy to assess residential mobility and social practices in past populations; however, so far, it has only occasionally been applied to prehistoric contexts in the Mediterranean. In this paper, we present 87Sr/86Sr data of human and animal samples from several Neolithic sites in the Apulian Tavoliere (southeastern Italy), namely, Grotta Scaloria, Passo di Corvo, Masseria Candelaro and La Torretta/Poggio Imperiale. Data obtained from dental enamel reflect the local origin of the individuals and allowed us to differentiate function and meaning of the sites examined. In particular, within a generally homogeneous background of Sr signatures, the range of 87Sr/86Sr at Scaloria Cave is greater than at the other sites, with variation likely to be related to funerary practices. We interpret this as the evidence of the ritual use of the cave, which implied the gathering of people of different origin. The relative variation of the Sr signature among individuals, either intersite or intrasite can be tentatively associated with mobility during life as well as with social practices, such as access to foods from geologically different environments.

We present the geomorphological map of the northwestern part of the Kurdistan Region of Iraq, where the landscape expresses the tectonic activity associated with the Arabia-Eurasia convergence and Neogene climate change. These processes influenced the evolution of landforms and fluvial pathways, where major rivers Tigris, Khabur, and Great Zab incise the landscape of Northeastern Mesopotamia Anticlinal ridges and syncline trough compose the Zagros orogen. The development of water and wind gaps, slope, and karsts processes in the highlands and the tilting of fluvial terraces in the flat areas are the main evidence of the relationship between tectonics, climate variations and geomorphological processes. During the Quaternary, especially after the Last Glacial Maximum, fluctuating arid and wet periods also influenced local landforms and fluvial patterns of the area. Finally, the intensified Holocene human occupation and agricultural activities during the passage to more complex societies over time impacted the evolution of the landscape in this part of Mesopotamia.

The human microbiome has recently become a valuable source of information about host life and health. To date little is known about how it may have evolved during key phases along our history, such as the Neolithic transition towards agriculture. Here, we shed light on the evolution experienced by the oral microbiome during this transition, comparing Palaeolithic hunter-gatherers with Neolithic and Copper Age farmers that populated a same restricted area in Italy. We integrate the analysis of 76 dental calculus oral microbiomes with the dietary information derived from the identification of embedded plant remains. We detect a stronger deviation from the hunter-gatherer microbiome composition in the last part of the Neolithic, while to a lesser extent in the early phases of the transition. Our findings demonstrate that the introduction of agriculture affected host microbiome, supporting the hypothesis of a gradual transition within the investigated populations.

We present new, full geomagnetic field vector results from three Neolithic ovens discovered at the archaeological site of Portonovo (Marche, Italy). The discovered structures are a rare example of very well preserved underground ovens from the Early Neolithic period. Standard thermal demagnetization procedures were used to isolate the direction of the Characteristic Remanent Magnetization acquired by the baked clay during the ovens' last firing. The corresponding archaeointensities were determined by the multi-specimen procedure (MSP-DSC) and show a clear intensity low during the Neolithic period. Both directional and intensity results are of high quality, offering the first contribution of full geomagnetic field vector data for this period in Italy. The new data are compared with other contemporaneous data from Europe and with global geomagnetic field models. Independent archaeomagnetic dating of the three ovens was also performed by means of the SCHA.DIF.14k model. The obtained results are in excellent agreement with available radiocarbon dates and confirm that all ovens belong to the Neolithic. These new data importantly enrich our knowledge of the geomagnetic field during the Neolithic period that is poorly documented by data, not only in Italy but also in the whole of Europe and show that archaeomagnetic dating can provide precise results even for prehistoric periods
