Early husbandry practices in highland areas during the Neolithic: the case of Coro Trasito cave (Huesca, Spain)

Conceptualization

Research on animal management strategies in high mountain areas during the early Neolithic ( , -, cal BC) has been conditioned by the presumption that human occupations in highland areas had a prominent seasonal character and the economic practices focused mainly on the exploitation of wild resources.The results obtained in the framework of research developed recently on settlement dynamics during the early Neolithic in the highland areas indicate the existence of relatively permanent occupations and the exploitation of domestic resources.Regarding livestock, the role of caprine transhumance in highland areas has been highlighted traditionally, conferring a marginal role to husbandry activities and emphasizing principally the temporary maintenance of herds of sheep and goats.In this study, we use the archaeozoological data and δ C and δ N stable isotopes composition of the faunal bones collagen to characterize the husbandry practices in Coro Trasito cave (Huesca, Spain).The results obtained demonstrated the presence of diverse herd foddering strategies within husbandry practices characterized by taxonomic diversity and multipurpose exploitation suggests that during the Neolithic, Coro Trasito cave played a more complex role than sheepfold.Moreover, the presence of the four main domestic species indicates the adaptation of herds of Coro Trasito to the cave environment, flocks with diverse dietary needs and reproductive behaviors.The results are discussed with an integrated analysis of the data related to animal management strategies in highland areas (more than , m. asl) during the early Neolithic, in particular in the central Pyrenees area.

Introduction
The study of animal management strategies in high mountain regions of the Iberian Peninsula during the Early Neolithic (c.5,700-4,500 cal BC) has been influenced by the assumption that settlements in these areas were primarily seasonal.This assumption has linked the settlements to pastoral or transhumant activities from the beginning of the Neolithic, emphasizing the role of caprine transhumance in highland areas (Martín et al., 2010;Rojo-Guerra et al., 2013, 2014;Lancelotti et al., 2014;Tornero et al., 2018;Tejedor-Rodríguez et al., 2021).However, new research as well as the discovery of new archaeological sites have revealed a wide range of situations, evidencing many complex mixed farming models involving interactions between plant and animal herding (Ebersbach, 2010;Antolín et al., 2018;Villalba-Mouco et al., 2018;Sierra et al., 2019;Gassiot et al., 2021Gassiot et al., , 2022)).In Iberian Pyrenees, Antolín et al. (2018) demonstrate that the settlement dynamics during the Early Neolithic could have been characterized by relatively permanent occupations and the exploitation of domestic resources.Clear evidence of permanent activity at the mountain sites would include agriculture practices, along with other practices linked to medium-to-long-term strategies, such as the storage of plant-based products (Antolín et al., 2017).Regarding livestock, the presence of the four main domestic species (Bos taurus, Sus domesticus, Ovis aries, and Capra hircus) has been evidenced in the archaeological sites located above 900 m in the Iberian Pyrenees during the Neolithic (with the exception of the Zatoya site: Antolín et al., 2018, p. 88).In the sites where domesticates have been identified, various uses and exploitations of these animals have also been documented (Viñerta, 2015;Antolín et al., 2018;Sierra et al., 2019;Viñerta and Saña, 2019).
Recent research about the Neolithisation process and the socioeconomic dynamics trends of the Neolithic in the central Pyrenees has revealed livestock management practices in the surrounding areas of the Neolithic settlements documented at altitudes ranging from 1,400 to 1,800 m asl (Clemente-Conte et al., 2014;Antolín et al., 2018;Gassiot et al., 2018Gassiot et al., , 2022;;Obea et al., 2021).Sites such as Coro Trasito cave, Cueva Lóbrica, Els Trocs, and Cova del Sardo demonstrate well-established human communities engaged in agricultural and husbandry activities by the end of the sixth millennium and the beginning of the fifth millennium cal BC (Clemente-Conte et al., 2014;Gassiot et al., 2018Gassiot et al., , 2022)).Activities related to local deforestation were observed at Els Trocs and Cova del Sardo.These activities included the clearing of vegetation and the presence of species associated with anthropic action.This suggests activities associated with local grazing and agriculture (Gassiot et al., 2012(Gassiot et al., , 2022;;Uría, 2013;Rodríguez-Antón, 2020).However, the scenario is more complex.While Els Trocs and Cova del Sardo document the main domesticates, it is characterized as an occupation closely linked to the seasonal exploitation of caprines (Navarrete and Saña, 2013;Rojo-Guerra et al., 2013, 2014;Gassiot et al., 2018), while Coro Trasito reflects a diverse and complex economic spectrum (Clemente-Conte et al., 2016;Viñerta and Saña, 2019).Additionally in Cova del Sardo and Coro Trasito provide evidence of dairy consumption (Tarifa, 2019).
In this context, settling in mountain regions may not exclude greater permanence and/or more intensive management of these areas.It can involve specialized husbandry practices, leading to the simultaneous management of domesticates, different productive purposes and specific feeding practices.These strategies can encompass activities within the local grazing areas, through mobility strategies, or involve the provision of forage.Considering that each domesticate exhibits distinct requirements and behaviors, a combination of planning and control mechanisms becomes essential to ensure the wellbeing and reproduction of the herds.Although more works address this problem in the Iberian Peninsula (Navarrete et al., 2017(Navarrete et al., , 2019;;Tornero et al., 2018;Sierra et al., 2019;Martin et al., 2021;Navarrete et al., Accepted;Tejedor-Rodríguez et al., 2021), there is still a gap in information on animal management strategies during the Neolithic in mountain areas, and the characterization of grazing areas, foraging strategies, and the relation of the herds with the environmental characteristics of the area, the type of site and the use of the settlement.The combined use of archaeozoological and stable isotope analysis can provide us with the keys to the study of pastoral management strategies (Madgwick et al., 2012;Balasse et al., 2016;Navarrete et al., 2017, Accepted).
The main objective of this research is to characterize husbandry practices at the Coro Trasito site during the early Neolithic, emphasizing the management strategies of domesticates.Using archaeozoological and stable carbon and nitrogen isotope analysis in bulk collagen, we will evaluate the animal ecology, herd management and feeding strategies implemented in Coro Trasito.The results will also be discussed within the framework of the neolithisation models proposed for the Iberian Peninsula and, especially, for the central area of the Pyrenees.

Coro Trasito (Tella-Sin, Huesca)
Coro Trasito is a large cave located on the southern slope of the Sierra de Las Tucas in Tella-Sin, Huesca, Spain, at 1,540 m a.s.l (Figure 1).This cave has an entrance that is 30.2 m long and 4.4 m high, with a maximum depth of 16.4 m (Clemente-Conte et al., 2014).According to the climatic classification of J. Papadakis, the site is located on the border of the cold temperate and humid Patagonian climate (MAPAMA, 1996), with an average temperature of 7.3 • C (Ninyerola et al., 2005).The site is located in a current area of moors and heathland (CORINE Land Cover, 2018).Between the highest areas of the Sierra de Las Tucas and the cave, natural grasslands provide grazing access for livestock during the summer.Below the cave mouth, there are slopes suitable for cultivation and with historic terraces.Adjacent to these historic terraces are mixed forests and coniferous forests (CORINE Land Cover, 2018).
Although the cave was documented in the 1970's, it was not until 2011 that systematic archaeological work began with a test pit (2011 and 2013) in order to evaluate the archaeological sequence and, since 2014, an excavation in extension (Figure 2).The first survey carried out in 2011 and 2013 uncovered antrophic occupations from the early Neolithic (5,320-4,365 cal BC), during the second half of the Second Millennium cal BC (1,430-1,130 cal BC) and, finally, to the Contemporary era (Clemente-Conte et al., 2014, 2016;Gassiot et al., 2018).Regarding Neolithic occupations three phases were identified dating from 5,300-5,000 cal BC, 4,990-4,885 cal BC, and 4,785-4,585 cal BC (Figure 3).The initial phase of cave occupation is characterized by its use as stable for animals.From c. 4,800 cal BC, the presence of domesticates and the use of space for storage in small pits, as well as for habitation and work area was documented (Clemente-Conte et al., 2020).The analysis of archaeological remains suggests the complexity of the occupation dynamics at the site.The predominance of domestic animals remains was recorded, highlighting pigs (Sus domesticus) and cattle (Bos taurus) in the early layers (Viñerta, 2015).Additionally, the consumption of dairy products is evidenced from the analysis of organic residues (Tarifa, 2019).Carpological remains of naked barley (Hordeum vulgare var.nudum) and naked wheat (Triticum aestivum s.l./durum Desf./turgidumL.) were recovered (Antolín et al., 2018).The presence of Bromus sp., Polygonum convolvulus, Galium aparine, and Chenopodium sp. has also been documented (Antolín et al., 2018).Pollen analysis reveals a high representation of cereals, suggesting the existence of nearby crop fields (Obea et al., 2021).Among the ceramic fragments recovered, both culinary and storage use have been identified (Díaz Bonilla et al., 2016).The presence of tools related to ceramic production indicates the carrying out of various artisanal activities at the site (Clemente-Conte et al., 2016).Furthermore, the presence of a wide range of tools such as grinding stones and sickles, along with storage pits, suggest that Coro Trasito could have functioned as a relatively stable occupation throughout most of the year, rather than being a specialized and seasonal site (Clemente-Conte et al., 2016, 2020;Clemente-Conte and Mazzucco, in press).

Materials and methods . Archaeozoological analysis
A total of 822 faunal remains corresponding to the Neolithic levels from Coro Trasito have been analyzed.Three hundred and twenty faunal remains belong to the occupations dated ca.5,300-4,900 cal BC (N-I), and 502 faunal remains to those dated ca.4,900-4,700 cal BC (N-II).In this study, only the remains that have been identified anatomically and taxonomically are presented (NISP_total = 395; NISP_N-I = 194; NISP_N-II = 206), focusing on domestic herds.
The bones were systematically classified both anatomically and taxonomically using the reference collection at the Laboratori d'Arqueozoologia of the Autonomous University of Barcelona (Spain), in addition to several reference manuals.For this study, the archaeozoological analysis has focused on the study of taxonomic representation frequencies and the estimation of the   (Lyman, 1994).We estimate the age of the death using a combination of the estimation of stages of tooth wear (Grant, 1982;Payne, 1985Payne, , 1987;;Jones, 2006;Lemoine et al., 2014), eruption sequences and epiphyseal fusion in postcranial elements (Silver, 1969;Barone, 1976;Amorosi, 1989;Zeder, 2006). .

Carbon and nitrogen analysis
Twenty-one faunal individuals were selected from N-II for stable carbon and nitrogen isotope analysis in bulk collagen.We selected a range of herbivores [n = 11, including domestic (Ovis aries, Capra hircus, Bos taurus) and wild animals (Capra pyrenaica, Capreolus capreolus], omnivores (n = 9, Sus domesticus, Ursus arctos), and carnivores (n = 1, Vulpes vulpes).Samples for stable isotope analysis correspond to adult individuals previously determined through archaeozoological analyses (MNI and age estimation).The samples included the diaphysis of long bones, maxilla, mandibular diastema and phalanx.Specimens were selected to represent individual animals by sampling the samesided portion of a specific element.When this was not possible, different specific elements from different archaeological layers, the same level: N-II, were analyzed.The N-I could not be sampled due to its high fragmentation and the thermal alterations of remains resulting from the fumier levels.
Collagen extraction and stable isotope analysis were performed at the Laboratori d'Arqueozoologia (Department of Prehistory) and Unitat d'Antropologia Biològica (Department Animal Biology, Plant Biology, and Ecology) at the Autonomous University of Barcelona (Spain).Faunal bone samples were collected with a rotary drill and cleaned to remove contaminating materials.Collagen extraction followed a modified Longin (1971) method (Brown et al., 1988;Richards and Hedges, 1999;Craig et al., 2010).Collagen samples weighing 0.3 mg were subjected to analysis using a Thermo Flash 1,112 elemental analyzer (EA) coupled to a Thermo Delta V Advantage isotope ratio mass spectrometer (IRMS) with a Conflo III interface, at the Institute of Environmental Science and Technology (ICTA-UAB) (Spain).The average analytical error was <0.2‰ (1σ) for δ 15 N and <0.1‰ (1σ) for δ 13 C as determined from the duplicate analyses of δ 13 C and δ 15 N.As a control, the international laboratory standard IAEA 600 (caffeine) was employed.For δ 13 C, the Vienna PeeDee Belemnite (V-PDB) was used, while air N 2 (AIR) served as the standard for δ 15 N. To assess the δ 13 C values, one-way ANOVA test (α = 0.05) was employed, preceded by the verification of normal distribution through the Shapiro-Wilk test for normality (α = 0.05).Thus comparison between the δ 15 N values was performed using the Kruskal-Wallis test (α = 0.05).All statistical tests were performed using PAST 3.x (Hammer et al., 2001).2).If the representation frequencies of domesticates are compared in N-I and N-II, an increase in the relative number of pig remains to cattle can be observed, as well as a higher number of sheep remains compared to goats in N-II.The minimum number of individuals (MNI) for each species in the Neolithic levels is different (MNI_total_N-I = 22; MNI_total_N-II = 17).In N-II, pigs show the highest increase in MNI among domesticates (N-I, MNI_pig = 2; N-II, MNI_pig = 6).Differences in the level of fragmentation within the faunal assemblages could explain the variation in the MNI between N-I and N-II for the Ovis/Capra.Slaughtering patterns were analyzed per taxon.Pigs were killed between 18 and 21 months old; and cattle killed at more than 24 months old.For both levels, sheep and goats presented a rather similar pattern, were also primarily killed at between 6 and 24 months of age in N-I and between 12 and 24 months of age.In the N-I a large proportion of newborn and infantile caprines (41% of MNI) were also recovered (0-3 months of age).This proportion of neonates decreases in N-II (6% of MNI).

. Archaeozoological analysis
Neonate and infantile individuals <3 months of age have not been able to be classified into specific categories due to the high degree of fragmentation of the remains and, in some cases, the absence of identifying features of the species.

. Carbon and nitrogen stable isotopes
Of the 21 samples analyzed, 19 samples exhibited satisfactory C% and N% ranged from 22 to 45% and 11 to 16%, respectively, with C:N ratios ranging from 3.2 to 3.6 and falling within the values proposed by DeNiro (1985), Ambrose (1990), and Van Klinken (1999) for preserved collagen.Although attempted repeatedly, collagen could not be extracted from samples 13 and 14.Data from the stable isotope analysis can be found in Table 3 and Figure  The average δ 13 C values of wild herbivores was −20.11 ± 0.17‰ (n = 3).When the Ursus arctos sample was included with wild herbivores, although it is an omnivorous species its diet is mainly herbivorous, the average δ 13 C values for the wild herbivorous-omnivorous species was −20.08 ± 0.15 ‰ (n 4).The average δ 13 C values of domestic herbivores was −20.18 ± 0.38‰ (n = 8) (Figure 4).Statistical tests showed that there are no significant differences in δ 13 C between wild and domestic herbivores (p > 0.6) and wild herbivores and domestic herds (p > 0.5).Likewise, there are no significant differences in δ 13 C between domestic herds (p > 0.8).
The average δ 15 N values of wild herbivores was 3.60 ± 0.11‰ (n = 3), and 3.61 ± 0.09‰ with Ursus arctos (n = 4).The average δ 15 N values of domestic herbivores was 4.28 ± 1.08‰ (n = 8).Statistical tests showed that there are no significant differences in δ 15 N between wild and domestic herbivores (p > 0.26) and wild herbivores and domestic herds (p > 0.27).Among herds, only the δ 15 N values were significantly different between cattle and goat (p = 0.008).Cattle were 15 N-enriched by 2.3‰ compared to the goat.Although there are no significant differences between wild herbivores and herds, wild herbivores were 15 N-enriched by 0.37‰ compared to pigs, 0.58‰ compared to sheep and 1.64‰ compared to cattle.Surprisingly, goats have a depletion of −0.67‰ compared to wild herbivores (Figure 5).

Discussion
The results obtained from archaeozoological and isotopic analysis of Coro Trasito emphasizes the role of domestic animals in the highland areas and the complexity of the Neolithisation process in the central Pyrenees, where livestock and agriculture may have played roles different from those traditionally assumed for medium and high mountain areas (Antolín et al., 2018;Tornero et al., 2018;Sierra et al., 2019;Alt et al., 2020;Gassiot et al., 2021Gassiot et al., , 2022;;Palomo et al., 2022).The importance of domesticates in early Neolithic layers of Coro Trasito is reinforced by the presence of the four main domestic species and a diversified husbandry strategy.The exploitation of caprines played a central role in the husbandry practices.Sheep flocks acquired progressively greater economic importance, as demonstrated by their increase during the N-II.The relative abundance of animal remains from neonate and infantile age, in N-I, could indicate the use of the cave as a stabling and/or breeding area.Martín et al. (2016) clarify that herders usually prefer to separate pregnant females from the rest of the herd to minimize risks during calving periods.In addition, excavations carried out in Coro Trasito have documented clearly stratified deposits of fumier (Clemente-Conte et al., 2014, 2016;Gassiot et al., 2018).Additionally, the presence of remains of infantile animals in N-I and N-II could also be related to dairy exploitation (Helmer, 1992).The analysis of the pottery waste from Coro Trasito shows how some of the Neolithic containers were used for dairy products (Tarifa, 2019).Furthermore, the documentation at Coro Trasito of the agriculture practices (Antolín and Jacomet, 2015;Antolín et al., 2018), supports the full development of practices such as agriculture and livestock in high mountain areas during the early Neolithic, leaving behind the character of traditionally granted marginal territory.
The breeding and maintenance of four different animal species, with diverse dietary requirements and reproductive behaviors, demonstrates an adaptation of herds to the cave environment.The wide availability of essential natural resources, including water and a wide variety of animal and plant resources, present in the various ecosystems (river valleys and forests) in the area, allowed the human communities that lived in Coro Trasito cave to exploit various ecosystems in the immediate surroundings.This is demonstrated by the archaeozoological results with the diversity of wild and domestic species exploited and the results of the carbon and nitrogen stable isotopes analyzed in bone collagen.The herbivore δ 13 C values suggest a terrestrial environment dominated by open C3-plants (De Niro and Epstein, 1978;O'Leary, 1988).The low variation and little dispersion in the δ 13 C values of herbivores and omnivores (amplitude of 1.67‰) and the nonexistence of significant differences between the specimens analyzed, could indicate that the feeding areas of the Coro Trasito herds are similar between them.
The δ 15 N values increase due to arid conditions or vary depending on soil type and manuring effect (Ambrose and Norr, 1993;Handley et al., 1999).The δ 15 N values documented in wild herbivores are low and very little variable compared to sheep, pigs and cattle herds.Goat herds have lower δ 15 N values than wild herbivores.The low δ 15 N values in the goats may indicate grazing in an environment less impacted by humans, for example on soils that had not been used for agricultural practices or areas with less aridity.
In contrast, sheep have a different isotopic signature than goats.According to studies by Hodgson et al. (1991) and Dumont (1997), sheep are more readily including non-herbaceous plants into their diet.But Müldner et al. (2014) suggest that incorporating herbaceous or non-herbaceous plants into their diet seldom leads to discernible isotopic differences between the species in temperate C 3 environments.Three hypotheses could potentially account for the ./fearc. .(Mellor and Stafford, 2004).It has been documented that the cereals were manipulated inside or in close proximity to the cave (Antolín et al., 2018;Obea et al., 2021), which could indicate the consumption of agricultural remains by the flocks.The impact of animal dung on plant δ 15 N values varies significantly and is influenced by factors such as the manuring rate and the type of fertilizer used (Fraser et al., 2011;Szpak, 2014).Firstly, δ 15 N values for Coro Trasito sheep could reflect the consumption of agricultural surpluses, such as crop stubble.Secondly, the δ 15 N values could indicate that the sheep flocks had the opportunity to graze in the manured fields.
Thirdly, the enrichment of δ 15 N values could be due to feeding in a closed place such as a stable.In Coro Trasito, the fumier levels and the presence of neonates inside the cave have been interpreted as the cave serving as a stable for caprines (Viñerta and Saña, 2019;Clemente-Conte et al., 2020).The cattle in the analyzed sample exhibit the highest δ 15 N values.This enrichment in δ 15 N may be attributed, similar to sheep, to factors like access to cultivated fields or the provision of surplus crops as forage.Furthermore, Bogaard et al. (2007Bogaard et al. ( , 2013) ) document that grains contain higher values of δ 15 N than manured cereal straws.Unfortunately, due to the extensive fragmentation of faunal remains, it has been impossible to conduct analyses on bone pathologies in the extremities of the studied cattle individuals.These analyses would have been useful to characterize tasks related to activities such as field maintenance.The archaeobotanical record of Coro Trasito suggests the presence of agricultural practices in the vicinity of the cave during the Neolithic period (Clemente-Conte et al., 2016;Antolín et al., 2018;Obea et al., 2021).The abundance of cereals and the existence of adventitious plants in an area previously densely forested imply the presence of small-scale crop fields near the cave (Clemente-Conte et al., 2016;Obea et al., 2021).Several lines of evidence support this hypothesis, including high pollen counts from both cereals and adventitious plants, the discovery of straw from both free-threshing and non-free-threshing cereals, and the carpological record of cereals at various stages of processing for consumption, indicating that cereals were manipulated inside or in close proximity to the cave (Antolín et al., 2018;Obea et al., 2021).Additionally, the discovery of multiple storage pits inside the cave indicates that the storage of plant products, such as cereals, might  have played a significant role in the subsistence strategies at Coro Trasito (Gassiot et al., 2018).Lithic tools were also recovered that show the processing of the cereal, both in harvesting and grinding (Clemente-Conte et al., 2016).
Finally, the δ 13 C values of the pigs present the broadest range of variation compared to the other specimens analyzed.This variability in δ 13 C values suggests access to a broader range of plant resources compared to the other flocks.This could imply that they were free to roam in forested environments in addition to the use of the same landscape areas for grazing.Furthermore, the δ 15 N values indicate that pigs primarily consumed plant-based products, with values close to wild herbivores, although also of sheep.The variability in δ 15 N values could be explained by access to products as by-products of crop production, such as cereals and/or legumes.Alternatively, this variability could be related to the variation in the amount of animal protein ingested (Hamilton and Thomas, 2012).For example, the pigs' diet could have included worms, insects, or small animals, as well as human food waste such as garbage or the discarding of animal remains from butchery activities.Similar interpretations have been proposed for prehistoric pigs that were potentially raised within extensive herd management systems, characterized by semi-free to free-range regimes with plant-based diets for the Central Pyrenees (Villalba-Mouco et al., 2018) and Northeast of the Iberian Peninsula (Navarrete et al., 2017).In addition, the mortality profiles documented in Coro Trasito, where pigs are slaughtered at around 18 and 21 months of age, closely resemble those seen in traditional agricultural societies with extensive systems (Hadjikoumis, 2012).
The increase in MNI of pigs in N-II could suggest a greater interest in pig production.The decrease in subadult caprine individuals and the increase in infantile individuals may indicate greater use of derived products such as milk.Pigs could cover the food needs that until now had been met by caprines.This change in the composition of flocks during the Neolithic has also been documented in the Can Sadurní cave (Saña et al., 2015).The significant increase in the number of pig specimens and access to a broader range of plant resources documented by stable isotope analysis may be related to the adaptability of this species to different environmental conditions.It is important to note that pigs have a high reproduction rate and can adapt to different husbandry strategies, making them a versatile source of meat and other products such as fat or marrow (Crosby, 1986).Furthermore, the use of other pig by-products, such as fat, has been recorded in Coro Trasito.Tarifa (2019) reports a range of n-alkanoic acids (fatty acids) that are attributable to a source of non-ruminant adipose fat and related to pig fat in 7 of the 19 ceramic containers analyzed.
Finally, the presence of the four main domestic species is documented in Coro Trasito and the results of MNI analysis show that the size of each flock would be composed of a few individuals of each species.This type of flocks with few individuals is also documented in the Cova del Sardo (Navarrete and Saña, 2013) and Cova Colomera (Martín and Oms, 2021) sites.

Conclusion
The study of highland areas such as the mountainous zone of the Pyrenees has brought new and important data about the dynamics of neolithisation process, particularly focusing on economic practices.Husbandry practices played an essential role in the economic strategies of Coro Trasito during the early Neolithic.
The presence of diverse herd foddering strategies within husbandry practices characterized by taxonomic diversity and multipurpose exploitation suggests that during the Neolithic, Coro Trasito played a more complex role than sheepfold.The increase of MNI pig in N-II shows the importance of this specie in meat production during the Neolithic.Moreover, the results obtained demonstrated the rapid adaptation of herds of Coro Trasito to the region, flocks with diverse dietary needs and reproductive behaviors.The combination of archaeozoology and isotopic results and archaeological context suggests that Coro Trasito was not primarily a site for shortterm occupations.
Furthermore, the presence of transformation activities related to dairy and fat products, and the existence of storage structures within the cave indicates the complexity of neolithisation processes in the central Pyrenees and how these areas were quickly integrated into a broader economic system.
