EvoAdapta UC successfully concludes the III excavation campaign at Aitzbitarte III

The cave is located near San Sebastian sourrounding by eight caves with prehistoric art and human occupation along the Upper Palaeolotithic 

After twelve days of excavation at the Aitzbitarte III cave, the EvoAdapta group from the University of Cantabria, along with the ERC SUBSILIENCE project and the Prehistoric Technology Laboratory from the University of Salamanca, successfully concluded the 3rd archaeological campaign. The cave, which belongs to a set of Paleolithic sites, is located in the municipality of Rentería-Gipuzkoa, in the Basque Country, within an area known as Landarbaso.

Aitzbitarte is a small limestone hill that houses nine caves named Aitzbitarte I to IX after the stream that flows at their base. The largest sites are III, also known as the “lower large cave,” and IV, known as the “upper large cave.” Paleolithic hunters inhabited these caves, with indications of the Lower Paleolithic and Aurignacian are found in the third cave.

Human Subsistence Refuge

The ERC SUBSILIENCE project focuses on studying human subsistence strategies through the analysis of 20 key sites located in southern European refuges, specifically in Serbia, Croatia, Italy, and Spain. One of these refuges, the easternmost part of the northen Iberian peninsula, is the Aitzbitarte III cave.

Through various analyses and combining of multidisciplinary techniques, the project aims to reconstruct paleoeconomic, paleoclimatic, and paleoecological conditions with high-precision chronology. This is helping to determine which specific subsistence patterns (if any) favored Homo sapiens over Neanderthals and to what extent climatic fluctuations affected Neanderthal extinction in each study area, ultimately proposing an explanation on a pan-European level.

Bringing science to young minds!

Yesterday, we had visitors at EvoAdapta and Subsilience. The third-grade classes from San Agustín School in Santander came to see our laboratory, and we took the opportunity to conduct some outreach activities related to SUBSILIENCE project. Through various games, we were able to talk to them about Neanderthals and bioarchaeology techniques.

We were amazed at the students’ level of knowledge in Prehistory.

For us, it is very important to transfer science through education so that students can envision themselves as future scientists or archaeologists. Role models are very important.

Participation in the XV. Achaeological Meetings in Bilbao

This Friday, Ana B. Marín-Arroyo, Principal Investigator of the SUBSILIENCE project, will give a lecture at the Archaeological Museum as part of the XV Archaeological Meetings.

The lecture, titled “Was Diet the Determining Factor Leading to Neanderthal Decline?”, will explore the hypothesis of how the Neanderthals’ diet may have influenced their survival and eventual disappearance.

The event promises to be a fascinating discussion on archaeology and human evolution, providing new insights into our ancestors.

 

PREHGASTRO Lays the Foundation for Creating a Solid Bridge Between Prehistory and Gastronomy

The first edition of the archaeogastronomic congress “PREHGASTRO: From Prehistory to the Plate” was held at the Palacio de la Magdalena in Santander on April 16 and 17. The initiative, co-organized by the EvoAdapta research group ans the ERC Subsilience project of the University of Cantabria (UC), the Marketing Intelligence group (UC), and the Ronquillo Restaurant (Ramales de la Victoria – Cantabria), achieved its goal of transferring scientific knowledge obtained by EvoAdapta researchers about prehistoric diets in the region. This was accomplished through five scientific lectures focusing on terrestrial meat, marine, and plant diets, the origin of dairy products, and key health aspects of Prehistory.

The debates following each lecture, featuring a panel of professionals from various disciplines, connected this knowledge with the current dietary and gastronomic reality of Cantabria. The event served as a unique meeting point for communicators and gastronomy enthusiasts, cultural heritage experts, archaeologists, researchers, nutritionists, producers, and chefs who explored the origins and evolution of food in Cantabria from the past to the present.

FIRST DAY: MEATS, FISH, AND VEGETABLES
The event’s inauguration was presided over by the Mayor of Santander, Gema Igual; the Regional Minister of Culture, Tourism, and Sport of Cantabria, Eva Guillermina Fernández; the Vice-Rector for Research and Scientific Policy of the University of Cantabria, Carlos Beltrán; the Director of the Office of Food Quality (ODECA), Juan Luis Centeno; and the Principal Investigator of the EvoAdapta research group at the University of Cantabria (UC), Ana B. Marín-Arroyo.

The first scientific lecture, titled “The Prehistoric Stomach,” was given by Ana B. Marín-Arroyo. Following the talk, EvoAdapta researcher Lucía Agudo moderated the round table “THE GRILL,” a debate on the consumption of animal protein in gastronomy, featuring experts from academia, gastronomy, and business such as the president of IBERTUR, Jordi Tresserras; the Associate Professor of Prehistory at the University of Salamanca and director of LABTEC USAL, Olivia Rivero; the gastronomic journalist, Rosa Rivas; the Commercial and Marketing Director at CANTUR S.A., José Ramón Álvarez; the chef of Ronquillo Restaurant, David Pérez; and the director of the National Museum of Altamira Research Center, Pilar Fatás.

Regarding her participation, Fatás noted about PREHGASTRO: “For me, the multidisciplinary approach has been the key to the success of this congress; the synergies generated will surely result in highly creative and scientifically rigorous gastronomic proposals. It has been a long time since I participated in a congress with such clear practical application, pure knowledge transfer.” During this first day, the director of PARADORES, José Carlos Campos Regalado, attended as an invited guest, also praising the event’s originality and sustainability: “This project is the zero kilometer of zero kilometers, both in product and in preparation and cooking! Gastronomic culture viewed from the origin, with rigor and science.

The afternoon session began with a lecture by Marie Skłodowska-Curie researcher at EvoAdapta-UC, Alexandre Lefebvre: “Unearthing Depths, Spines, and Whales.” The scientific talk, focused on prehistoric marine diets, continued with the debate “A Thorn in the Side,” discussing the current use of the marine environment and sustainable fish consumption. Participants included the chef and owner of La Casona del Judío, Sergio Bastard; the Director of Marketing, Communication, and Innovation at Grupo Consorcio, Eduardo San Filippo; the PhD in Biological Sciences, Gerardo García-Castrillo; the professor in the Department of Geography, Urban Planning, and Land Management (UC), Juan José González Trueba; the gastronomic journalist Jorge Guitián; and the president of the Cantabria Rural Tourism Association, Jesús Blanco.

The last scientific lecture of the day was given by the archaeobotanist and CSIC Research Professor, Leonor Peña-Chocarro, under the title “Chewing the Root and the Origin.” She explored the plant elements that were part of the prehistoric diet, from seeds to fungi. The subsequent panel, titled “Raw,” addressed the issue of plant proteins today and the use of plants in contemporary cuisine, featuring participants such as El Diario Montañés journalist, Jose Luis Pérez; the innovator at the Basque Culinary Center, Blanca del Noval; the researcher at the CIDAF Technological Center, Ana Lemus; the farmer and gatherer from El Jardín del Cocinero, Raúl Díez; and the chef and writer, Iolanda Bustos. This chef, who advocates the use of flowers in cooking, emphasized that cuisine is a channel to explain the landscape and territory. “In gastronomy, people seek to be moved and go to the origin. I try to create edible landscapes with flowers. We are denaturalized and disconnected,” she added.

SECOND DAY: DAIRY AND HEALTH
“Down to the Last Drop,” the session led by the University of Valladolid researcher, Borja González-Rabanal, transported the audience to the Neolithic to explore the gradual introduction of dairy into the human diet from Anatolia to Europe, revealing the impact of this new food on prehistoric societies.

This was followed by the round table “The Blend: Dairy Today,” moderated by gastronomic communicator Claudia González. The debate brought together experts in cooking, anthropology, communication, and artisanal cheese making to discuss the contemporary relevance of dairy, highlighting sustainable projects and culinary innovations. Participants included the anthropologist and director of the Department of Historical Sciences at the University of Cantabria, Eloy Gómez-Pellón; the specialist in communication, health, and gastronomy, Carmen Ordiz; the owner of La Lleldiría cheese factory, Sarah Hart; the chef and gastronomic communicator, Antonio Vicente; and the president of the Spanish Network of Field and Artisan Cheese Makers (QueRed), Chema Alonso.

This round table emphasized the consumption of local and seasonal products, connected with food sovereignty and territorial identity that translates into gastronomy. The manager of the Local Action Group Valles Pasiegos, Ana Manrique, invited as an audience member, noted that “PREHGASTRO has demonstrated that when the University approaches the endogenous resources of our rural environment, initiatives of high value emerge to support sustainable development processes, with the ability to generate very positive impacts on the social and economic growth of the territory based on local values.

The last scientific dissemination session was led by the Ramón y Cajal researcher at the Madrid Museum of Natural Sciences, Almudena Estalrrich-Albo, under the title “Sustaining the Body: Teeth, Organisms, and Well-being.” Estalrrich shared how teeth, as fossil records, reveal vital information about health, diet, and daily life in the past. PREHGASTRO culminated with the round table “The Good and the Bad Sip,” moderated by Ángel Herrero, Professor of Marketing at the University of Cantabria. This discussion reflected on the current role of food in a globalized world, questioning whether we truly know what we eat, with guests including the specialist doctor in Endocrinology and Nutrition at the Marqués de Valdecilla University Hospital (HUMV), Luis Alberto Vázquez; the doctor in Archaeology and university professor, Sandra Lozano; Professor of Physical Anthropology at the University of the Basque Country, Sandra Lozano; the doctor in Biotechnology and scientific communicator, Ricardo Moure; and the chef at Cenador de Amós, 3 Michelin Stars, 2022 National Gastronomy Award, Jesús Sánchez. The chef closed his participation in the debate saying: “We are what we ate and we should not lose this tradition.”

LIVE COOKING: BITES INSPIRED BY PREHISTORY
Considering the knowledge acquired during the scientific lectures at PREHGASTRO, once the variety of prehistoric diets in the region was unraveled, four Cantabrian chefs bridged the gap between the past and the present by fusing Prehistory with contemporary cuisine. They used ingredients like venison, fruits, cereals, milk, and salmon to create four “living cuisine” bites that exemplify the scientific knowledge transfer from the EvoAdapta group to professionals in other disciplines.

Alex Ortiz, from Pan de Cuco restaurant (Suesa), honored the terrestrial meat diet with a venison toast, plum, and flowers, reminding us that long ago, before meat dominated our tables, flowers and fruits were the protagonists of our diet. The marine diet was represented in this gastronomic connection by chef Samuel Fernández from El Remedio restaurant (Ruiloba), who prepared a salmon taco accompanied by a bone marrow emulsion with hazelnuts and wild asparagus.

The plant essence, captured by Miki Rodríguez from Umma restaurant (Santander), materialized in a bite where the apple served as a vessel for a wild mushroom broth with pine oil, accompanied by the top of the apple, used as a spoon, holding a filling of cereals, roots with a touch of hazelnut miso, and cherry soil. Finally, Tamara Zubillaga from Romy restaurant (Bádames) delighted the guests with a curd of raspberries accompanied by a millet cookie, a tribute to the dairy products also discussed at the PREHGASTRO congress.

Drawing Contest: The Role of Women in Prehistory

A drawing contest was organized as part of the March 8th celebrations: International Women’s Day, and February 11th: International Day of Women and Girls in Science. Schoolchildren from various primary and vocational education centers in Cantabria participated in this contest, where they had to depict the role of women in Prehistory.

The aim of this contest was to challenge the traditional roles associated with women in the past (for example, the belief that there were no female hunters). After receiving hundreds of drawings, three participants were awarded for their originality and scientific representation. The prizes included visits to the Museum of Prehistory, books about women scientists, and a tour of the EvoAdapta laboratory.

The winners were: 

FIRST PRIZE: Olivia Artabe Abásolo | 3rd year ESO | IES Ría del Carmen

SECOND PRIZE: Emma Fernández García | 2nd year FPB | CIFP La Granja

THIRD PRIZE: Deva Fernández López | 2nd year ESO | Colegio Sagrada Familia

Coexistence of Neanderthals and Homo sapiens in Europe Influenced by Herbivore Abundance

Coexistence of Neanderthals and Homo sapiens in Europe Influenced by Herbivore Abundance

Led by researchers from the University of Cantabria and published in the journal Science Advances, this is the first study to assess the causes of the disappearance of Neanderthals at a European level

The scientific community has proposed two main hypotheses to explain the decline and ultimate extinction of Neanderthals: climate change and the appearance of early Homo sapiens. Both factors directly impacted the availability of food resources in nature. However, until now, the effect of these two causes on herbivore populations, a primary source of human diet, had not been quantified. Researchers from the EvoAdapta group at the University of Cantabria, Ana B. Marín-Arroyo and Marco Vidal Cordasco, are evaluating, for the first time at a European scale, the causes of the disappearance of Neanderthals during the transition from the Middle to Upper Paleolithic as part of the ERC SUBSILIENCE project (ERCEA-818299).

The study, titled Neanderthal coexistence with Homo sapiens in Europe was affected by herbivore carrying capacity, has been published in the American scientific journal Science Advances and proposes a new hypothesis: differences in herbivore abundance between regions resulted in unequal food availability, affecting competition between species and the coexistence between Neanderthals and Homo sapiens.

Research Objectives

The main factors analyzed in this study were to quantify the productivity of terrestrial ecosystems during the last glacial period or Marine Isotope Stage 3 (MIS3) in each European region, provide an updated chronological framework for the transition from the Middle to Upper Paleolithic, and evaluate the association between ecosystem productivity and the spatial and temporal patterns of Neanderthal replacement by H. sapiens across the continent.

Key Findings

The results show that in regions where Neanderthals disappeared before the arrival of H. sapiens, the potential availability of exploitable herbivores was lower than in areas where both species coexisted. It has also been observed that there is an association between herbivore carrying capacity and the duration of coexistence between sapiens and Neanderthals. When herbivore abundance is higher, the period of coexistence between both species is longer.

These findings expand upon previous research published in Nature Ecology & Evolution and suggest that with the arrival of H. sapiens in Europe, trophic pressure on available resources likely increased, but with varying effects in different continental regions. In areas with greater food resource abundance (Southern France, Danube Basin, Rhone Basin, Mediterranean areas of the Iberian Peninsula), competition would have been lower, and the coexistence between both species more prolonged.

Methods Employed

Through various multidisciplinary methods, it was possible to determine how the carrying capacity of European ecosystems affected regional differences in the timing of Neanderthal replacement by our species. First, a wide range of datings and herbivore species recovered from archaeopaleontological levels dated in MIS3 (the coldest period in Europe) were compiled. Climate simulation was obtained from a general atmospheric circulation model validated with two different paleoclimatic indicators: pollen records and stable isotopes obtained from stalagmites. This allowed for the estimation of Net Primary Productivity (NPP) in the vicinity of each archaeological and paleontological site between 55,000 and 30,000 years before present.

Furthermore, European biogeographic regions were defined based on paleoclimatic conditions, faunal composition, and temporal trends in NPP during the study period. An updated chronology of Neanderthal disappearance and replacement by early H. sapiens in each European region was established using Bayesian models, a common method in archaeology, and optimal linear estimates, a methodology widely used in ecology to estimate the extinction time of species but still rarely used in archaeology.

Finally, a macroecological model validated with current observations was used to estimate the carrying capacity of herbivore species in each region through a regression analysis that incorporates uncertainty in chronological and ecological estimates.

Six ‘live conversations’ to explain climate change from Prehistory to the present day

 The  research group of the University of Cantabria, EvoAdapta, organizes and moderates these sessions at the Tabacalera Civic Center in Santander.

 

Global warming is one of the most important challenges facing humanity and the scientific community today. The increase in Earth’s temperature represents a threat to the environment, biodiversity and the stability of ecosystems. To find out if there were changes in the ecosystems of the past and what future challenges the next generations face, the group of the University of Cantabria (UC), EvoAdapta, organizes a cycle of live conversations that addresses the ‘Climate change: from prehistory to the present’.

In an informative interview format, different scientists will respond to relevant questions about global warming. Through six conversations, structured in blocks, from the past to the present, the causes, consequences and possible solutions to climate change will be explored with the aim of bringing the actions and science of this phenomenon closer to society.

The event will feature researchers from the University of Murcia, the Institute of Physics of Cantabria (IFCA), the Institute of Environmental Hydraulics of the UC (IH), the British multinational engineering company associated with the University of Cambridge, Mott MacDonald, and the Institute of Biomedicine and Biotechnology of Cantabria (IBBTEC). The Santander Tobacco Civic Center and the Santander City Council will host these sessions, which will be held at 7:00 p.m. with free entry until capacity is reached.

 

FIRST LIVE CONVERSATION

The first session will take place on October 25, led by the Full Professor in Prehistory (UC) and Head of the EvoAdapta R&D Group, Ana B. Marín-Arroyo. Inaugurating the past block, the researcher will focus on addressing the climate changes that occurred in the ecosystems of the species that preceded Homo sapiens: the Neanderthals. Were they able to adapt to climate variability? What were your survival strategies in the face of these fluctuations? Marín-Arroyo will reveal some of the causes that motivated their decline, as well as she will make an x-ray of which animal species coexisted with the Neanderthals, depending on the climatic period in which they were found.

Regarding this species, there are hypotheses and theories that arouse interest within the scientific community and, thanks to her SUBSILIENCE project, funded by the European Research Council (ERC), Ana B. Marín-Arroyo investigates the different ecological environments exploited by Neanderthals in the southern European peninsulas together with a team of international researchers.

FUTURE SESSIONS

Continuing with the past, on November 9, it will be the turn of the scientific paleoillustrator and Doctor in History, Geography and History of Art from the University of Murcia and, member of the ECCE HOMO research group, Gabriela Amorós, together with the paleobotanist and Professor of Evolutionary Botany at the same university, José Carrión. Both will explore the synergies that arise when reconstructing the landscapes of the past through science and art.

Starting the present block, on December 13, the researcher from the Institute of Physics of Cantabria (IFCA), Maialen Iturrioz, will focus on the evaluation of knowledge and the different lines of evidence available in the present to foresee possible scenarios of change climate in the future.

On January 12, climate changes on the coast and its infrastructure will be explored with UC Professor and head of the Climate Risks, Adaptation and Resilience Group of the Institute of Environmental Hydraulics (IHCantabria), Javier López Lara.

Future challenges that revolve around the effects of global warming on water resources and flooding will be presented on February 9 by Civil Engineer and Master in Hydrology, David Ocio. The Engineer currently leads the climate resilience area for the United Kingdom and Europe at the British multinational Mott MacDonald. And, to close the cycle of conversations, on March 15, we will focus on one of the crises of which we have already observed some of its effects. The Doctor in Molecular Biology and researcher of the Intergenomics R&D group of the Institute of Biomedicine and Biotechnology of Cantabria, Raúl Fernández López, will focus his session on the impact of climate change on people’s health and the appearance of bacteria and pandemics.

The assessment of environmental conditions shows new insights about Neanderthals’ disappearance in Northern Iberia

The assessment of environmental conditions shows new insights about Neanderthals’ disappearance in Northern Iberia

Researchers from the University of Cantabria published in the scientific journal Quaternary Science Reviews a detailed analysis of the environmental records including microfauna, pollen, charcoals and isotopes in herbivore remains, found in archaeological sites

The study of past climatic and environmental changes is essential to understand human behaviour during Prehistory. The Cantabrian Region, in Northern Iberia, is a key region to unravel the Neanderthals replacement by our species (Homo sapiens). The research “Reassessing paleoenvironmental conditions during the Middle to Upper Palaeolithic transition in the Cantabrian region” published in the scientific journal of Quaternary Science Reviews, offers a regional view of the environmental conditions experienced from 55,000 to 25,000 years: a decisive period when those species inhabited.

The publication is leaded by researchers from University of Cantabria, Mónica Fernández-García, Ana B. Marín-Arroyo and Marco Vidal-Cordasco, and from the University of Lancashire in the United Kingdom, Jennifer Jones. The study answers one of the main objectives of the Subsilience ERC Project: to identify the causes of the Neanderthals decline in the southern European peninsulas by assessing the role that climate might had in human subsistence during MIS3. To do so, an in-depth analysis of the available environmental records recovered from archaeological and palaeontological sites has been carried out. Information about small-mammals, pollen, charcoals, and stable isotopes in herbivores is included.

 

Research outputs

The results of the study show highly variable environmental changes throughout the archaeological levels, in line with the climatic fluctuations observed in the marine and ice core records. Therefore, this research has not only homogenised the existing data (making them available and open to the scientific community), but also has modelled these data to obtain temperature and precipitation estimations, associated with concise radiocarbon chronologies.

The findings reveal a significant climatic shift that may have affected both human populations in the north of the Iberian Peninsula. Specifically, there is a progressive trend from the Mousterian to the Aurignacian towards colder temperatures, increasing aridity and landscapes opening, especially from 48,000 to 44,000 years, matching the late Neanderthal occupations, followed by a population hiatus, prior to the arrival of Homo sapiens.

 

The value of the study

Despite the multiple environmental indicators available, the research highlights the fragmentary nature of the regional record during this key period for human evolution and highlights the necessity of further research to obtain a high-resolution regional environmental record, which will allow us to continue to understand the causes behind this human extinction.

 

ERC Subsilience project

The SUBSILIENCE project, which promotes this work developed in the University of Cantabria, is funded by the ERC – European Research Council, the main European funding organization for research at the forefront of excellence, created by the European Union in 2007. SUBSILIENCE focuses on the subsistence strategies adopted by Neanderthals and early Homo sapiens in the peninsulas of southern Europe and evaluate the role that MIS3 climatic changes might had in their resilience as a species.
