The Genomic Legacy of Human Management and sex-biased Aurochs hybridization in Iberian Cattle

From the initial expansion of domestic cattle into Europe during the Neolithic period, taurine cattle (Bos taurus) and their wild ancestor, the aurochs (B. primigenius), had overlapping ranges leading to ample opportunities for intentional and unintentional hybridization. We performed a bioarchaeological analysis of 24Bosremains from Iberia dating from the Mesolithic to the Roman period. The archaeogenomic dataset allows us to investigate the extent of domestic-wild hybridization over time, providing insight into the species’ behavior and human management by aligning changes with cultural and genomic transitions in the archaeological record. Our results show frequent hybridization during the Neolithic and Chalcolithic, likely reflecting a mix of hunting and herding or relatively unmanaged herds, with mostly male aurochs and female domestic cattle involved in hybridization. This is supported by isotopic...
Hacia una conceptualización y representación visual estratigráfica desacoplada: el megalitismo como caso de estudio

Durante años, los conceptos y la metodología de representación usados para trabajar con información estratigráfica han sentado ciertas bases conceptuales, que han ido evolucionando hacia las prácticas en manejo de información estratigráfica actuales. En trabajos anteriores se han realizado análisis profundos de dichos enfoques conceptuales y sus correspondientes representaciones visuales en diferentes soportes y formatos: más cercanos a bocetos y dibujos, representaciones 2d y 3d, etc. La irrupción de tecnologías y aplicaciones software que asisten al arqueólogo en la conceptualización, manejo y representación visual de la información estratigráfica nos permitió realizar un recorrido por dichas aproxima...
With shepherds and sheep on the way to neolithisation: a comprehensive approach to the archaeological evidences of Els Trocs Cave (San Feliú de Veri/Bisaurri, Huesca)

Together with a great team of specialists in different areas of knowledge, we present an update of our research process. The site is a cave that was occupied for more than two millennia, from the Early Neolithic (the end of the 6th millennium cal. BC) to the Late Neolithic (the end of the 4th millennium cal. BC). The groups who currently and seasonally visited the cave focussed their main economic activity in sheep herding. For that chronology, they practised a very specialised management system comprising the vertical movement of livestock (an incipient transhumance) from the river Ebro Basin to the mountains. The combination of analytical research, including micromorphology, zooarchaeology, carbon and oxygen isotopic analyses, archaeobotany, palaeoparasitology, traceology, or the study of the raw material provenance and the similarities of tipology, technology and decoration in pottery compositions provide a comprehensive overview of the subsistence universe of these human groups. Finally, the anthropological and genetic studies help to gain insights into the life experiences of some of individuals who occupied the cave throughout two long cycles of use.[ES] El proyecto de investigación desarrollado en la cueva de Els Trocs se ha convertido en un ejemplo de transdisciplinariedad. De la mano de un amplio equipo de especialistas en distintas áreas de conocimiento, presentamos una puesta al día del proceso de investigación. El yacimiento es una cueva con actividad antrópica durante más de dos milenios, desde el Neolítico antiguo (finales del VI milenio cal. BC) hasta el Neolítico final (finales del IV milenio cal. BC). Sus ocupaciones son recurrentes y estacionales y una de las actividades económicas fundamentales de sus ocupantes debió de ser el pastoreo de ovino, un sistema de explotación muy especializado para la época, que comportaba movimientos altitudinales del ganado desde las tierras de la depresión del Ebro hasta las montañas pirenaicas (incipiente trashumancia). Los análisis micromorfológicos, carpológicos, sedimentológicos, los estudios de la fauna y la microfauna, de los isótopos de carbono y oxígeno, la paleoparasitología, la traceología, la procedencia de las materias primas y las similitudes de las formas, técnicas y composiciones decorativas cerámicas nos ofrecen una visión completa del universo subsistencial de estos grupos humanos. Por último, los análisis antropológicos y genéticos arrojan luz sobre las peripecias vitales de algunos de los individuos que ocuparon la cueva a lo largo de dos amplios ciclos de uso.Peer reviewe

Were the rivers roads of borders in the Prehistory?: continuities and discontinuities of the Megalithism throughout the Douro basin

It covers the upper part of the peninsular Central Plateau, both in Spain and Portugal, and the Portuguese littoral platform. This river is born in the inner of the Iberia, in the province of Soria, and flows into Porto, so much of its route is in the Atlantic territory. But its most singular feature is that currently it marks the border between the two countries, Portugal and Spain, along the area called `International area of the Douro river. This work presents some results of a research in development about the megalithic biographies, based on an exhaustive identification and description of the different phases of use, reuse and constructive, reconstructive and destructive processes in each Megalithic monument, and its diachronic comparison through the application of different chronometric and statistical analyses. The main goal is to identify differentiated behavioural patterns in the use of these contexts over time, but also over the space. In this sense, the Douro Basin is a very suitable territory for this type of research because it presents a wide geomorphological diversity and heterogeneity (valleys, mountains, moor). In this presentation I will show what role the Douro river played as a road for prehistoric societies and will highlight the role that this river might have played as a road for the communities along the coastal zone of the Atlantic Façade into this area. It will be seen that there were changes in its importance and functionality as a route of communication and exchange. To demonstrate this, different study variables will be compared, such as architectural types. We shall look at the idea of whether or not the current geographic `line¿ of the Atlantic Facade is arbitrarily false

These results allow us to complete the population pyramid of a settlement, analyse mortality trends and relate individuals of a particular sex or age-at-death category to possible funerary rituals, lifestyles and/or states of health and disease. In this work, we carry out a paleodemographic analysis of a singular tomb: the chalcolithic burial site of Camino del Molino, Murcia, SE Spain. The tomb hosted 1348 individuals (30.7% non-adults and 69.3% adults) over two contiguous funerary phases, spanning a large part of the third millennium BC, which makes it a reference site for knowledge of the Recent Prehistoric populations. For this purpose, we estimated different paleodemographic parameters (life tables, mortality rates and sex ratios) and compared them to model life tables of preindustrial populations and data from other contemporary p...
Transhumant shepherds of the Old Neolithic in a high mountain environment: chrono-cultural sequence at Els Trocs Cave (San Feliú de Veri, Huesca)

The careful and detailed work of excavation and recording has revealed a complex stratigraphy in which, thanks to the radiocarbon dates on short-lived samples (cereal seeds, human bones and domestic animal remains), it has been possible to distinguish four different periods of occupation inside the cave. With this information and some preliminary analyses of part of the materials (pottery, flint and faunal remains), we have documented the presence of a human group in the mountain pastures of the axial Pyrennes, at a very early stage (beginning of the last third of the VIth millennium cal. BC), with a transhumant pastoral economy. It was a fully neolithic population with clear evidences of the use of wheat and barley, despite they did not cultivate around the close environment of this cave, where complex burial rituals had been also documented.[ES] Este trabajo presenta los resultados preliminares obtenidos en la excavación de la Cova de Els Trocs, desarrollada dentro del proyecto de investigación "Los caminos del Neolítico". La minuciosa labor de excavación y de registro ha permitido establecer una compleja secuencia estratigráfica en la que, gracias a una veintena de dataciones radiocarbónicas sobre eventos singulares de vida corta (semillas de cereal, huesos humanos y fauna doméstica), se han podido diferenciar cuatro momentos de ocupación distintos de la cueva. Con estos datos y algunos análisis, también preliminares, de parte del registro (cerámica, sílex y restos faunísticos), se ha podido definir, en una época muy temprana (inicios del último tercio del VI milenio cal. BC.), la presencia en los pastos de montaña del Pirineo axial de un grupo humano que desarrolla una actividad pastoril trashumante. Una población plenamente neolitizada, que conoce el trigo y la cebada, aunque no los cultive en el entorno de la cueva, y que, a tenor de ciertas evidencias, practica complejos rituales tanatológicos.La línea de investigación principal de este trabajo se desarrolla en el marco del proyecto “Los Caminos del Neolítico” (HAR2009-09027), bajo la dirección del Dr. Manuel Rojo Guerra, concedido por la Subdirección General de Proyectos de Investigación/Dirección General de investigación y gestión del Plan Nacional de I+D+I/Secretaría de Estado de Investigación, del Ministerio de Ciencia e Innovación, y co-financiado por el Gobierno de Aragón. Del mismo modo, la parte analítica se enmarca dentro del proyecto “Origins and spread of agriculture in the western Mediterranean region” (ERC-2008-AdG 230561), coordinado por la Dra. Leonor Peña Chocarro y financiado por el European Research Council. También, buena parte de la investigación relativa al estudio antropológico y su datación, ha sido sufragada por la German Research Foundation (Al 287/14-1).Peer reviewe
Early Neolithic tombs from the interior of Iberia: new data for an updating of the empirical evidences

The aim is to show a general overview of the burial evidences of the first farmers in this region.[ES] A la vez que dar a conocer tumbas y cronologías inéditas de los inicios del Neolítico en el interior peninsular, se pretende analizar con el detalle que nos permite en cada contexto la bibliografía existente, todos los casos de tumbas de esta fase en el interior peninsular y en el Valle del Ebro. Serán analizados con detalle el tipo de estructura utilizada y la naturaleza del depósito funerario, la edad y el sexo de los enterrados, el tipo de ajuar, su presencia o ausencia en cada caso, así como la posición y la orientación de los difuntos en la tumba. Todo ello con la intención de ofrecer una visión integral de las evidencias funerarias en los inicios de la economía con rendimientos diferidos.Peer reviewe
Megaliths on the edge: The Place of Cultural Transformation
Trabajo presentado en la 26th Virtual Annual Meeting of the European Association of Archaeologist... more Trabajo presentado en la 26th Virtual Annual Meeting of the European Association of Archaeologists (EEA), celebrada del 24 al 30 de agosto de 2020.This session wishes to address approaches and interpretations that determine understandings and values that may have been shared within the greater Megalithic tradition of Europe’s Atlantic coastline. Whilst the building of megalithic monuments, which includes stone tombs, standing stones and megalithic buildings, is a worldwide, time-transcending phenomenon, hundreds of thousands were erected across Europe, and thousands of these monuments still exist in situ, highlighting their past and continued relevance in the European Landscape. Significantly in Europe, it appears that most of them were built in the coastal regions where they altered natural places enduringly, with new constructions continuing for more than 2000 years. Despite possible forms of cultural continuity or similarities of community practices, from the times before and after the first appearance of megaliths, the megalithic tradition is often seen by archaeologists as a phenomenal cultural transformation. This transformation has been variously interpreted as sets of conversions, acculturations, absorptions and movements, or a series of all these, differing in temporality and location. Perhaps they were even part of some kind of cultural revolution. Interestingly, it seems that the point of commonality in this transformation may often have been the movement to, across or away from water. Our question in this session is: exactly what role did the Atlantic itself play in these transformations? This can be interpreted literally or figuratively. We want to know what can you tell us about the people and places you are studying in relation to the Atlantic just prior to, during or after the adoption of megaliths? Your research ´place´ could even be just next door but the adoption didn´t actually happen. Can you tell us why? Our session will focus on looking at ways of understanding the cultural topographies and transformations of people, places or regions by innovative research approaches – methodological and interpretive, or indeed have inspiring conclusions.Peer reviewe

Pathotropic neural stem and/or progenitor cells (NSCs) can potentially deliver therapeutic agents... more Pathotropic neural stem and/or progenitor cells (NSCs) can potentially deliver therapeutic agents to otherwise inaccessible cancers. In glioma, NSCs are found in close contact with tumor cells, raising the possibility that specificity of NSC contact with glioma targets originates in the tumor cells themselves. Alternatively, target preferences may originate, at least in part, in the tumor microenvironment. To better understand mechanisms underlying NSC interactions with glioma cells, we examined NSC-target cell contacts in a highly simplified 3-dimensional peptide hydrogel (Puramatrix) in which cell behaviors can be studied in the relative absence of external cues. HB1.F3 is an immortalized clonal human NSC line extensively characterized in preclinical investigations. To study contact formation between HB1.F3 NSCs and glioma cells, we first examined co-cultures of eGFP-expressing HB1.F3 (HB1.F3.eGFP) NSCs and dsRed-expressing U251 glioma (U251.dsRed) cells. Using confocal microscopy, HB1.F3.eGFP cells were observed contacting or encircling U251.dsRed glioma cells, but never the reverse. Next, examining specificity of these contacts, no significant quantitative differences in either percentages of HB1.F3 NSCs contacting targets, or in the extent of target cell encirclement, were observed when HB1.F3.eGFP cells were presented with various potential target cells (human glioma and breast cancer cell lines, patientderived brain tumor lines, non-tumor fibroblasts, primary mouse and human astroglial cells, and primary adult and newborn human dermal fibroblasts) except that interactions between HB1.F3 cells did not progress beyond establishing contacts. Finally cytoskeletal mechanisms employed by HB1.F3.eGFP cells varied with the substrate. When migrating in Puramatrix, HB1.F3 NSCs exhibited intermittent process extension followed by soma translocation, while during encirclement their movements were more amoeboid. We conclude that formation of contacts and subsequent encirclement of target cells by HB1.F3 NSCs is an intrinsic property of these NSCs, and that preferential contact formation with tumor cells in vivo must therefore be highly dependent on microenvironmental cues.
