Recent Sociocultural Changes Reverse the Long‐Term Trend of Declining Habitat Availability for Large Wild Mammals in Europe

ABSTRACTAimPeople have strongly influenced the biosphere for millennia, but how their increasing activities have shaped wildlife distribution is incompletely understood. We examined how the distribution of European large (>8 kg), wild mammals has changed in association with changing anthropogenic pressures and climate change through the Holocene.LocationEurope.MethodsWe used over 17,000 zooarchaeological records of 20 species spanning 12,000 years to develop time‐calibrated species distribution models, incorporating dynamic data on cropland extent, natural vegetation fragmentation, human population density and climate. We assessed habitat availability and potential species richness across time and within seven biogeographical regions. We also compared anthropogenic pressures at zooarchaeological record sites with present‐day habitats of remaining large mammals to evaluate recent increases in their potential for coexistence with human activities.ResultsWe found a continuous decline in potential large mammal species richness, particularly linked to changes in human population density. Most habitat loss became evident continentally after 1500 AD, but in the Atlantic and Mediterranean bioregions, habitat loss reached 20% during the Iron/Roman Ages (1000 BC–500 AD) due to increasing human population density. Climate change initially boosted species richness (+0.67 species/km2 on average) until the end of the Mesolithic but had negligible effects afterward. Today, large mammals appear to have a higher potential for coexisting with people compared to the past (e.g., herbivores today inhabit areas with a mean human population density of 95 people/km2, compared to an average of 17 people/km2 in the period 1500–2000 AD).Main ConclusionsOur study emphasizes the crucial role of anthropogenic pressures over natural climate change in determining the distribution and diversity of large mammal communities throughout history. Additionally, our results indicate that contemporary anthropogenic trends like land‐use de‐intensification and stronger conservation policies can counteract the impact of past, higher anthropogenic pressures and reverse defaunation.

The Population History of Domestic Sheep Revealed by Paleogenomes.

Sheep was one of the first domesticated animals in Neolithic West Eurasia. The zooarchaeological record suggests that domestication first took place in Southwest Asia, although much remains unresolved about the precise location(s) and timing(s) of earliest domestication, or the post-domestication history of sheep. Here, we present 24 new partial sheep paleogenomes, including a 13,000-year-old Epipaleolithic Central Anatolian wild sheep, as well as 14 domestic sheep from Neolithic Anatolia, two from Neolithic Iran, two from Neolithic Iberia, three from Neolithic France, and one each from Late Neolithic/Bronze Age Baltic and South Russia, in addition to five present-day Central Anatolian Mouflons and two present-day Cyprian Mouflons. We find that Neolithic European, as well as domestic sheep breeds, are genetically closer to the Anatolian Epipaleolithic sheep and the present-day Anatolian and Cyprian Mouflon than to the Iranian Mouflon. This supports a Central Anatolian source for domestication, presenting strong evidence for a domestication event in SW Asia outside the Fertile Crescent, although we cannot rule out multiple domestication events also within the Neolithic Fertile Crescent. We further find evidence for multiple admixture and replacement events, including one that parallels the Pontic Steppe-related ancestry expansion in Europe, as well as a post-Bronze Age event that appears to have further spread Asia-related alleles across global sheep breeds. Our findings mark the dynamism of past domestic sheep populations in their potential for dispersal and admixture, sometimes being paralleled by their shepherds and in other cases not.

The first complete genome of the extinct European wild ass (Equus hemionus hydruntinus).

We present palaeogenomes of three morphologically unidentified Anatolian equids dating to the first millennium BCE, sequenced to a coverage of 0.6-6.4×. Mitochondrial DNA haplotypes of the Anatolian individuals clustered with those of Equus hydruntinus (or Equus hemionus hydruntinus), the extinct European wild ass, secular name 'hydruntine'. Further, the Anatolian wild ass whole genome profiles fell outside the genomic diversity of other extant and past Asiatic wild ass (E. hemionus) lineages. These observations suggest that the three Anatolian wild asses represent hydruntines, making them the latest recorded survivors of this lineage, about a millennium later than the latest observations in the zooarchaeological record. Our mitogenomic and genomic analyses indicate that E. h. hydruntinus was a clade belonging to ancient and present-day E. hemionus lineages that radiated possibly between 0.6 and 0.8 Mya. We also find evidence consistent with recent gene flow between hydruntines and Middle Eastern wild asses. Analyses of genome-wide heterozygosity and runs of homozygosity suggest that the Anatolian wild ass population may have lost genetic diversity by the mid-first millennium BCE, a possible sign of its eventual demise.

Evidence of an age and/or gender-based division of labor during the Last Glacial Maximum in Iberia through rabbit hunting

Many archaeological assemblages from the Iberian Peninsula dated to the Last Glacial Maximum contain large quantities of European rabbit (Oryctolagus cuniculus) remains with an anthropic origin. Ethnographic and historic studies report that rabbits may be mass-collected through warren-based harvesting involving the collaborative participation of several persons. We propose and implement an Agent-Based Model grounded in the Optimal Foraging Theory and the Diet Breadth Model to examine how different warren-based hunting strategies influence the resulting human diets. We then visually compare the simulated diets with the zooarchaeological record. Our simulation outputs suggest that rabbits may have been mass collected from warrens by humans through the use of nets and an age and/or gender-based division of labor. Our results have profound implications for the comprehension of hunting behavior and the social organization of humans during the Last Glacial Maximum in the Iberian Peninsula.

The elusive zooarchaeological record of Somuncurá. An analysis of its distribution and variability

When we began studies on the Somuncurá plateau our expectations of finding abundant zooarchaeological material were great, because we would be working in the collective hunting fields reported by 19th century chroniclers. However, and although we obtained numerous archaeological results, the archaeofaunal record is scarce compared to the abundance of lithic materials, art or stone structures. Thus, the goal of this work is to evaluate the current state of knowledge contributed by this line of evidence to the study of plateau hunter-gatherer societies. For this, we considered the spatial distribution of these items, their archaeological contexts, the faunal structure of each assemblage and the presence of modifications of the bone surfaces in order to evaluate the role played by the different agents (natural and cultural) in the formation of assemblages, their importance for the preservation of this very elusive record in Somuncurá, and, finally, to contribute some trends that allow discussing the use of resources and whether the two sectors of the plateau exhibit differences. The taphonomic results at site scale do not indicate integrity problems that would explain the low frequency of this type of records, and raise the need to explore this problem at larger spatial scales. The zooarchaeological trends suggest that during the late Holocene, guanacos would have been the main species used by the societies that inhabited Somuncurá and that by the mid-19th century, these societies began to use fauna of European origin as a complement, in addition to native fauna.

Evidence of diverse animal exploitation during the Middle Paleolithic at Ghar-e Boof (southern Zagros)

Although Middle Paleolithic (MP) hominin diets consisted mainly of ungulates, increasing evidence demonstrates that hominins at least occasionally consumed tortoises, birds, leporids, fish, and carnivores. Until now, the MP zooarchaeological record in the Zagros Mountains has been almost exclusively restricted to ungulates. The narrow range of hominin prey may reflect socioeconomic decisions and/or environmental constraints, but could also result from a research bias favoring the study of large prey, since archaeologists have undertaken no systematic taphonomic analyses of small game or carnivores in the region. Here, we report on the first comprehensive taphonomic analysis of an MP faunal assemblage from Ghar-e Boof (∼ 81–45 kyr), a Late Pleistocene site in the southern Zagros of Iran. Anthropogenic bone surface modifications point to hominins as the main agent of accumulation. Hominins preyed primarily on ungulates, particularly wild goat. However, we also found evidence for MP hominin exploitation of carnivores and tortoises at the site. Although small game represents only a minor portion of the diet, our results suggest that the hunting behavior of MP hominins in the Zagros was more diverse than previously thought, similar to what we find elsewhere in Eurasia.

Reconsidering archaeological garden hunting: A view from the northern U.S. Southwest

Archaeologists frequently use garden hunting, or the hunting of animals from cultivated areas, to explain patterns in the zooarchaeological record of people who relied on agriculture. Rarely, however, have archaeologists systematically tested whether garden hunting actually occurred. For example, in the Northern U.S. Southwest, researchers often suggest that garden hunting explains the prevalence of lagomorphs, particularly cottontails (Sylvilagus spp.) but sometimes also jackrabbits (Lepus spp.), in zooarchaeological assemblages. We use stable isotope analysis of lagomorphs from three Ancestral Pueblo sites—Sand Canyon Pueblo, Hummingbird Pueblo, and Tijeras Pueblo—to test this suggestion. We find that garden hunting does not seem to explain either cottontail or jackrabbit abundance in these assemblages. We propose alternate approaches to understanding this subsistence practice in the U.S. Southwest and elsewhere.

The prelude to industrial whaling: identifying the targets of ancient European whaling using zooarchaeology and collagen mass-peptide fingerprinting.

Taxonomic identification of whale bones found during archaeological excavations is problematic due to their typically fragmented state. This difficulty limits understanding of both the past spatio-temporal distributions of whale populations and of possible early whaling activities. To overcome this challenge, we performed zooarchaeology by mass spectrometry on an unprecedented 719 archaeological and palaeontological specimens of probable whale bone from Atlantic European contexts, predominantly dating from ca 3500 BCE to the eighteenth century CE. The results show high numbers of Balaenidae (many probably North Atlantic right whale (Eubalaena glacialis)) and grey whale (Eschrichtius robustus) specimens, two taxa no longer present in the eastern North Atlantic. This discovery matches expectations regarding the past utilization of North Atlantic right whales, but was unanticipated for grey whales, which have hitherto rarely been identified in the European zooarchaeological record. Many of these specimens derive from contexts associated with mediaeval cultures frequently linked to whaling: the Basques, northern Spaniards, Normans, Flemish, Frisians, Anglo-Saxons and Scandinavians. This association raises the likelihood that early whaling impacted these taxa, contributing to their extirpation and extinction. Much lower numbers of other large cetacean taxa were identified, suggesting that what are now the most depleted whales were once those most frequently used.

Prehistoric and historic exploitation of marine mammals in the Black Sea

The recent exploitation of marine species is relatively well documented and understood in terms of impacts on species abundance, distribution, and resource use. In contrast, ancient exploitation of marine mammals remains poorly documented; in part, because a detailed meta-analysis of their presence in the zooarchaeological record is lacking. This is true in the Black Sea, where cetaceans are reported in the zooarchaeological record but have not yet been studied comprehensively. Here, we synthesize all available published and unpublished zooarchaeological data from 27 sites around the Black Sea, dating from the Mesolithic and Neolithic periods (6500-6000 BCE) to the Medieval period (641–1475 CE), to document the extent and nature of the exploitation of the Black Sea cetacean species. The results suggest that cetacean exploitation was practised continuously in the Black Sea over a period of 8500 years from the Neolithic through to the Medieval period. This suggests a much longer history of marine mammal exploitation in the Black Sea than previously understood, pushing back the timeline of human impacts on the Black Sea marine fauna.

An osteometric analysis of elk (Cervus elaphus manitobensis) from Great Smoky Mountains National Park

AbstractTeeth are commonly preserved in the zooarchaeological record and can be used to estimate the age of individuals in a faunal assemblage. However, there are currently no criteria for discerning the sex of elk based on dental metric characteristics. Here, we present the results of an osteometric analysis of modern elk (Cervus elaphus manitobensis) from Great Smoky Mountains National Park to create an age profile for the sample, establish metrical parameters for evaluating sex, and discern the relationship between age and size. The analysis of tooth development stages in younger elk was combined with the assessment of occlusal wear in older elk to create an age profile of our sample population. The length and breadth of mandibular third molars produced bimodal distributions that suggest these measurements can be used to differentiate sex in this population, and diastema length showed a curvilinear association with age (R2 = 0.71). This dataset provides a useful comparative sample for future studies on ageing and sexing in zooarchaeology, conservation paleobiology, and wildlife resources management.

Neolithic faunal resources in the center of the Iberian Peninsula. New evidence from El Mar (Meco, Spain)

The zooarchaeological evidence available for the Neolithic in the Iberian Peninsula is mostly condensed in the Mediterranean area, from Catalonia to Cádiz, and the Cantabrian area. This leaves an extensive region with little known evidence. The entire central zone of the Iberian Peninsula, specifically the Middle Tagus Valley, is a region for which there is not much information on the fauna uses. The reasons behind this gap are diverse, so any discovery in this region is relevant to expanding the available data. This paper presents the findings of a new archaeological site discovered during the last few years. El Mar, located in Meco (Madrid) offers evidence of cow and sheep domestication. And, thus, joins the existing zooarchaeological record for other nearby sites in the Middle Tagus Valley in the center of the Iberian Peninsula.

The paleo-synanthropic niche: a first attempt to define animal’s adaptation to a human-made micro-environment in the Late Pleistocene

Synanthropic behavior, i.e., the behavior of wild animals that benefit from a shared ecology with humans, has existed long before the sedentarization of Homo sapiens during the Neolithic, around 10,000 years ago. This study describes and discusses the concept of an older animal-human relationship: paleo-synanthropic behavior and the associated paleo-synanthropic niche. Key features of this new niche are anthropogenic food waste from mobile hunter-gatherers as a stable food base for small opportunistic scavengers and a human-near environment safe from large predators. By linking the niche to human behavior rather than to a specific location or structure, this niche was accessible for a long time, even in the Late Pleistocene. Like modern synanthropic animals, members of the paleo-synanthropic niche experienced an increase in population density and a decrease in home range. This, in turn, made it easier for humans to capture these animals and use them as resources for meat, fur, or feathers, as seen in the zooarchaeological record of many European Late Pleistocene sites. As a disadvantage, diseases such as zoonoses may have spread more easily.

Evolutionary radiation of mid-Holocene lanceolate points from the highlands of the South Central Andes

Through phylogenetic reconstruction this work  analyzes the  diversification of  lanceolate points of the South Central Andes   which began in the early Holocene and spanned the entire mid- Holocene. Based on a regional-scale data, we   discuss the links between the increasing mid-Holocene risk conditions, the patterns of diversification of point lineages, demographic change and animal resources consumption. We distinguish a first instance of greater diversity of points, a higher rate of innovation and less class longevity. These trends progressively stabilized, giving rise to a pattern of  less innovation, decreasing taxa diversity  and greater class longevity as well as an age-related extinction pattern. We show that as projectile points diversified,hunting efficiency increased along the mid-Holocene by the increased representation of  high-return fauna in the regional zooarchaeological record.  We suggest that this diversification of  lanceolate points was an adaptive evolutionary radiation which began with the increase in the rate of innovation for coping with the increasing risk of the beginning of mid-Holocene in the South Central Andes. From this we conclude that technological innovation was a prerequisite for the human specialization in camelid hunting and for the development of a highly economically efficient foraging strategy in the south Andean  highlands

Re-evaluating late Mesolithic economies

The late Mesolithic hunter-gatherers of what is now Denmark have long captivated archaeologists, who have meticulously studied the archaeological remains of their foraging economy since the mid-twentieth century. However, these studies – predominantly focused on subsistence – have often overlooked how individual decisions based on social and environmental settings can greatly structure foraging behaviours and, subsequently, the patterns observed in the zooarchaeological record. Perceiving hunting not just as an activity, but as a cultural practice shaping identities and social bonds, underscores the importance of considering social, symbolic and economic dimensions in Mesolithic hunting research. This study bridges this gap by integrating theoretical frameworks from human behavioural ecology (HBE), such as optimal foraging theory (OFT), costly signalling theory (CST) and notions of prestige. By doing so, it aims to elucidate the complex motivations underlying prey selection among the Ertebølle hunters. Through analysis of five sites from the Danish Ertebølle period (5400–3950 BC) using a simplified prey choice model (PCM), this research seeks to shed light on the interplay of ecological and social factors shaping hunting practices. The findings are discussed through the lens of optimal choice and prestige to examine patterns of prey selection at these archaeological sites.

Considering passenger pigeon abundance and distribution in the Late Woodland zooarchaeological record of southern Ontario, Canada

AbstractThe passenger pigeon (Ectopistes migratorius) was once the most abundant bird species in North America. Flocks of these birds witnessed in the early 19th century were so vast that they were said to darken the sky for days as they passed. Early syntheses of passenger pigeon remains in archaeological contexts in the eastern United States, in contrast, found them to be relatively rare in relation to other fowl, leading to the suggestion that the colonial‐era hyper‐abundance of passenger pigeons was a post‐European‐contact phenomenon resulting from contact‐induced demographic and ecological changes. In this paper, we provide new insights into passenger pigeon historical ecology through a synthesis and GIS‐based analysis of zooarchaeological data on skeletal remains from 157 Late Woodland (ca. 900–1650 CE) sites in Ontario, Canada. Our results reveal that passenger pigeon bones are common, and often abundant, in Late Woodland archaeological assemblages in Ontario, which speaks to the species' importance to Indigenous peoples in the region. However, the relative abundance of passenger pigeon remains varies over time, suggesting longer‐term trends in their availability and/or in hunting patterns.

Extended longevity of DNA preservation in Levantine Paleolithic sediments, Sefunim Cave, Israel

Paleogenomic research can elucidate the evolutionary history of human and faunal populations. Although the Levant is a key land-bridge between Africa and Eurasia, thus far, relatively little ancient DNA data has been generated from this region, since DNA degrades faster in warm climates. As sediments can be a source of ancient DNA, we analyzed 33 sediment samples from different sedimentological contexts in the Paleolithic layers of Sefunim Cave (Israel). Four contained traces of ancient Cervidae and Hyaenidae mitochondrial DNA. Dating by optical luminescence and radiocarbon indicates that the DNA comes from layers between 30,000 and 70,000 years old, surpassing theoretical expectations regarding the longevity of DNA deposited in such a warm environment. Both identified taxa are present in the zooarchaeological record of the site but have since gone extinct from the region, and a geoarchaeological study suggests little movement of the sediments after their deposition, lending further support to our findings. We provide details on the local conditions in the cave, which we hypothesize were particularly conducive to the long-term preservation of DNA—information that will be pertinent for future endeavors aimed at recovering ancient DNA from the Levant and other similarly challenging contexts.

New data and syntheses for the zooarchaeological record from the Lower Murray River Gorge, South Australia: Applying a ngatji lens

This article provides new data and syntheses for the zooarchaeological record of the Lower Murray River Gorge region in South Australia. The contribution of original data from Murrawong, Kangerung and Pomberuk provides rigorous and complementary records for the region. In particular, we supply new and detailed identifications for terrestrial vertebrate fauna and comment on prior published taxonomic identifications and methods. Using the Ngarrindjeri concept of ngatji we have also created a new lens with which to view the faunal assemblages. This new reading includes considerations of Lower Murray River Gorge diets in the Mid to Late Holocene, the presence/absence of certain species (inclusive of potential cultural influences) as well as the effects of European colonisation on animals (some now extinct or threatened) and the concomitant impacts for Ngarrindjeri people.

No sustained increase in zooarchaeological evidence for carnivory after the appearance of Homo erectus

The appearance of Homo erectus shortly after 2.0 Ma is widely considered a turning point in human dietary evolution, with increased consumption of animal tissues driving the evolution of larger brain and body size and a reorganization of the gut. An increase in the size and number of zooarchaeological assemblages after the appearance of H. erectus is often offered as a central piece of archaeological evidence for increased carnivory in this species, but this characterization has yet to be subject to detailed scrutiny. Any widespread dietary shift leading to the acquisition of key traits in H. erectus should be persistent in the zooarchaeological record through time and can only be convincingly demonstrated by a broad-scale analysis that transcends individual sites or localities. Here, we present a quantitative synthesis of the zooarchaeological record of eastern Africa from 2.6 to 1.2 Ma. We show that several proxies for the prevalence of hominin carnivory are all strongly related to how well the fossil record has been sampled, which constrains the zooarchaeological visibility of hominin carnivory. When correcting for sampling effort, there is no sustained increase in the amount of evidence for hominin carnivory between 2.6 and 1.2 Ma. Our observations undercut evolutionary narratives linking anatomical and behavioral traits to increased meat consumption in H. erectus, suggesting that other factors are likely responsible for the appearance of its human-like traits.

Biological and cultural history of domesticated dogs in the Americas

Domestication had a dramatic influence on the cultural evolution of human histories, and on the biological evolution of domesticated species. Domestic dogs occurred earlier in the Americas than other domesticated animals. Older records in the continent come from North America, dated 11 000-8400 years BP, and in the Andes from 5600-5000 years BP. In order to present an overview of human-dog interaction in the Americas, and to identify gaps in knowledge of this subject, we reviewed 178 publications on zooarchaeological record of burials, genetics, morphology, and ethnological information of American dogs, revisiting the history and interactions across the continent. There is no evidence of an in situ dog initial domestication. Pre-Columbian diversity in North America includes at least three varieties, whereas in South America six varieties were documented. Historical descriptions of phenotypes (e.g., humped dog) may represent an expression associated with mutations. We find that archaeological, historical, and ethnographic records reveal non-traditional uses and hybridizations with other canids. For example, the Coast Salish people exploited woolly dogs for manufacturing blankets. Dog acquisition by some Amazonian cultures began towards the end of the nineteenth century. Overall more than 41 dog breeds originated in the Americas and are currently recognized by kennel clubs. The main gap in knowledge points to the relationships between American breeds, local hybridizations, migratory routes of dogs following Indigenous peoples' social networks, historical-cultural contexts, and quantification of morphological diversity. North and Central American dogs have been more intensively studied than those from the Amazon regions or Patagonia. We find that the history of domestication in the Americas is far from simple and integrative studies are needed.

Scanning electron microscopy for differentiating charred endocarps of Rhus/Toxicodendron species and tracking the use of the lacquer tree and Asian poison ivy in Japanese prehistory

The use of natural lacquer for preservation and decoration of various commodities is a remarkable invention. In Japan lacquer production dates back to the Neolithic Jomon period and has been mainly based on the sap extracted from the lacquer tree (Toxicodendron vernicifluum (Stokes) F.A. Barkley). However, it is still unclear, if lacquer production evolved in Japan independently or was introduced from Neolithic China, another centre of early lacquer production. A debate also revolves around the origin of the lacquer tree itself and whether it occurs in Japan naturally or was introduced from the continent along with the skills required for lacquer production. Records of Rhus/Toxicodendron fruit remains, recovered from cultural layers of archaeological sites and natural palaeoenvironmental archives across Japan, provide an opportunity to answer the existing questions. This paper presents a method for differentiating charred endocarps of the six Rhus/Toxicodendron species growing in Japan, which is not feasible based on size or morphological properties of whole fruits or endocarps. To develop this method, we used a set of modern reference fruits. Identification is based on the species-specific tissue structure of the charred endocarp in longitudinal sectional view observed by scanning electron microscopy (SEM). We suggest a simple identification key that is based on two prominent traits of the endocarp’s tissue structure, i.e., tissue alignment and density. The method was successfully applied to an abundant record of charred Rhus/Toxicodendron endocarps recovered by flotation from Okhotsk culture layers dating to ca. 490–880 CE at the multi-component Hamanaka 2 archaeological site, Rebun Island, Hokkaido region, northern Japan. The recovered endocarps belong to Asian poison ivy (Toxicodendron orientale Greene, 1905) and the chronology of the archaeobotanical assemblages suggests that fruits and/or other parts of this plant were used by different local populations over a period of up to 3000 years (Final Jomon to Classic Ainu period). This indicates that not only lacquer tree was an important economic plant in Japanese prehistory, but also other Rhus/Toxicodendron species were used for unknown purpose. While use of T. orientale for medical effects or as an alternative source for lacquer production seems possible, we hypothesise that at Hamanaka 2 it was utilised for its high tannin content to tan hides and furs of sea mammals. This interpretation emphasises the discussed function of Hamanaka 2, famous for its rich zooarchaeological record of sea mammal remains, as an important site of marine hunting and raw material processing.
