[ES] Knowledge of the climatic and environmental changes of the start of Holocene and its impact on human populations and cultures is key to understanding both the predictive and future evolution of these. In this regard, the study using ditches and surveys of the holocene archaeosedimentary register in the area of the neolithic deposit of Los Cascajos (Los Arcos, Navarre) provides valuable information not only for establishing the environmental development of this area, but also for knowledge of the activities carried out by the residents of the deposit on the banks of the river Odrón. This work presents the results of the stratigraphic, sedimentological and geochemical study using high resolution XRF-CS of the LAC1 sounding. The data obtained indicate a trend towards aridification throughout the Holocene, represented by a cycle of agradation-incision in the river Odrón. The river sedimentary register also detects indicators of contemporary anthropic activity in the settlement of Los Cascgars, which makes it possible to place its occupation at hydrological times more humid than the current one, and to demonstrate the subsequent aridification of this area of the Ebro valley along the recent Holocene (Megalayense).

Sheep remains constitute the main archaeozoological evidence for the presence of Early Neolithic human groups in the highlands of the Southern Pyrenees but understanding the role of herding activities in the Neolithisation process of this mountain ecosystem calls for the analysis of large and well-dated faunal assemblages. Cova de Els Trocs (Bisaurri, Huesca, Spain), a cave located at 1564 m a.s.l on the southern slopes of the Central Pyrenees, is an excellent case study since it was seasonally occupied throughout the Neolithic (ca. 5312–2913 cal. BC) and more than 4000 caprine remains were recovered inside. The multi-proxy analytical approach here presented has allowed us to offer new data elaborating on vertical mobility practices and herd management dynamics as has not been attempted up until now within Neolithic high-mountain sites in the Iberian Peninsula. For the first time, δ18O and δ13C stable isotope analyses offer direct evidence on both the regular practice of altitudinal movements of sheep flocks and the extended breeding season of sheep. Autumn births are recorded from the second half of the fifth millennium cal. BC onwards. Age-at-death distributions illustrate the progressive decline in caprine perinatal mortality together with the rising survival rate of individuals older than six months of age and the larger frequency of adults. This trend alongside the 'off-season' lambing signal at the implementation of husbandry techniques over time, probably aiming to increase the size of the flocks and their productivity. Palaeoparasitological analyses of sediment samples document also the growing reliance on herding activities of the human groups visiting the Els Trocs cave throughout the Neolithic sequence. In sum, our work provides substantial arguments to conclude that the advanced herding management skills of the Early Neolithic communities arriving in Iberia facilitated the anthropisation process of the subalpine areas of the Central Pyrenees. ; This paper was supported by several projects awarded to MR-G: 'Los Caminos del Neolítico' (HAR2009-09027) and 'Los Caminos del Neolítico II' (HAR2013-46800 P) were granted by the National R&D&I Plan/Ministry of Economy, Industry and Competitiveness (https://www.ciencia.gob.es/portal/site/MICINN/) and co-financed by the Government of Aragón (https://www.aragon.es/), and 'La Memoria del Camino: Ciencia y divulgación de las primeras rutas pecuarias neolíticas en el Pirineo-MEDELCA' (FCT-2015-9947) was financed by the Spanish Foundation for Science and Technology (FECYT) (https://www.fecyt.es/).

This paper presents the results of the first excavation campaign of the Artusia rock shelter in Unzué, Navarre, Spain. Chronocultural and archaeobiological analyses revealed five different occupation phases (Artusia I–V) within the regional Mesolithic timeline, specifically in the Mesolithic of Notches and Denticulates (Artusia I and II) and the Geometric Mesolithic (Artusia III, IV, and V). In addition, the study of the sedimentological and palaeoenvironmental evolution in the entire record helped to clearly define several climatic events which developed around 6550 cal BC–8500 cal BP and 6250 cal BC–8200 cal BP. Here, we present a description of these events and their (pre)historical interpretation with the aim of recognizing how they influenced the Mesolithic hunter–gatherer groups living in the Ebro Basin of the Iberian Peninsula. ; projects "Los Caminos del Neolítico" -HAR2009- 09027- and "Los Caminos del Neolítico II" -(HAR2013-46800-P)- under directed by Dr. Manuel Rojo Guerra, granted by the Subdirectorate General for Research Projects/General Directorate of Research and Management of the National Plan for R and D and Innovation/Secretary of State for Research of the Ministry of Science and Innovation of Spain, and co-financed by the Government of Navarre.

Violence seems deeply rooted in human nature and an endemic potential for such is today frequently associated with differing ethnic, religious or socio-economic backgrounds. Ethnic nepotism is believed to be one of the main causes of inter-group violence in multi-ethnic societies. At the site of Els Trocs in the Spanish Pyrenees, rivalling groups of either migrating early farmers or farmers and indigenous hunter-gatherers collided violently around 5300 BCE. This clash apparently resulted in a massacre of the Els Trocs farmers. The overkill reaction was possibly triggered by xenophobia or massive disputes over resources or privileges. In the present, violence and xenophobia are controlled and sanctioned through social codes of conduct and institutions. So that, rather than representing an insurmountable evolutionary inheritance, violence and ethnic nepotism can be overcome and a sustainable future achieved through mutual respect, tolerance and openness to multi-ethnic societies. ; Funding for research at Els Trocs was provided by the German Research Foundation to K.W.A. (Al 287/14–1) "Reconstruction of population-dynamic processes on the Iberian Peninsula between Neolithic and Early Bronze Age using aDNA analysis", to M.R.G. under the Spanish National Plan for Scientific and Technical Research and Innovation and by the Government of Aragón (HAR2009–09027) "Los Caminos del Neolithico" and (HAR2013–46800-P) "Los Caminos del Neolithico II". Further analyses were carried out within the scope of Leonor Pena Chocarro's project "Understanding the Origins and Spread of Agriculture in the Western Mediterranean" (ERC-2008-AdG 230561).

Hepatitis B virus (HBV) has been infecting humans for millennia and remains a global health problem, but its past diversity and dispersal routes are largely unknown. We generated HBV genomic data from 137 Eurasians and Native Americans dated between ~10,500 and ~400 years ago. We date the most recent common ancestor of all HBV lineages to between ~20,000 and 12,000 years ago, with the virus present in European and South American hunter-gatherers during the early Holocene. After the European Neolithic transition, Mesolithic HBV strains were replaced by a lineage likely disseminated by early farmers that prevailed throughout western Eurasia for ~4000 years, declining around the end of the 2nd millennium BCE. The only remnant of this prehistoric HBV diversity is the rare genotype G, which appears to have reemerged during the HIV pandemic. ; The research was funded by the Max Planck Society, the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation program (771234–PALEoRIDER, to W.H.; 805268–CoDisEASe to K.
