Identifying palaeo-environments and changes in Aboriginal subsistence from dual-patterned faunal assemblages,south-western Australia

Palaeo-environments and past human subsistence patterns are difficult to determine from dual-patterned faunal assemblages where human and non-human predators have accumulated and intensively modified animal bones. This paper examines such records in the Leeuwin–Naturaliste Region of south-western Australia, where a thin belt of coastal limestone contains caves and rock shelters with rich faunal deposits. The Late Pleistocene and Holocene part of this record derives from four archaeological sites: Devil's Lair, Tunnel Cave, Witchcliffe Rock Shelter and Rainbow Cave. Correspondence analysis combined with cluster analysis enables a preliminary assessment of habitat changes using simple species abundances in the faunal assemblages and comparison with indices of past human activity in the sites and the species’ present habitat preferences. These inferred changes, consistent with previous analyses of faunal remains and tree charcoal, suggest that late Holocene sites document Aboriginal occupation in coastal heath, scrub and woodland. Late Pleistocene deposits record hinterland occupation at times of low sea-level when the coast was up to 30 km seawards of its present position and the surrounding vegetation was open-forest or woodland. As rainfall increased and vegetation changed in the Holocene, species foraging in open-woodland declined or became locally extinct, while species requiring closed canopy habitats increased. Rank-order correlations of taxa and archaeological remains from depositional sequences before and after the environmental change indicate that the occupiers of late Holocene sites favoured the same generalist species that occupiers of Late Pleistocene sites had favoured, which were available at all times. Prey habitats, foraging behaviours and historic records of ethnographic hunting and settlement pattern suggest that this local continuity is consistent with maintenance of a “dispersive mode” subsistence pattern in the region.     

Dating North Asian surface assemblages with ostrich eggshell: implications for palaeoecology and extirpation

East Asian ostrich (Struthio anderssoni Lowe) was thought to have become extinct sometime in the Late Pleistocene. Petroglyphs portray ostrich with Pleistocene animals, and ostrich eggshell (OES) fragments and ornaments from Holocene sites were considered to be older fossils. Here we summarize previous radiometric dates for ostrich eggshell (OES) and present 15 new calibrated accelerator mass spectrometry (AMS) dates, indicating that ostrich survived in Mongolia and northern China until at least 8.9 ka BP. The dates in our sample population suggest a correlation between Struthio and warm steppe environments, with extirpation probably related to essential changes in Holocene steppe ecosystems including human expansion. This study assesses the usefulness of Asian OES for archaeological dating by AMS, constrains the date of Asian ostrich extirpation, and investigates palaeoenvironmental implications of ostrich survival and extinction.     

The Shell-Bearing Archaic in the Middle Cumberland River Valley

The Middle Cumberland River Valley (MCRV) of Tennessee comprises a unique regional environment that has continually supported human occupation along the natural river levees and adjacent terrace landforms since the Late Pleistocene. Over thousands of years Archaic period inhabitants of the MCRV harvested the invertebrate species that populated the streams and waterways of the region, using them for subsistence and raw materials and taking an active role in managing the riverine resources. The cumulative result of this process appears in the archaeological record as abundant and often-dense deposits of invertebrate zooarchaeological remains. However, few formal archaeological investigations have been conducted on Archaic shell-bearing sites in the region. In this field report we present initial results of site file analysis, radiocarbon dating, and species composition research in order to introduce the MCRV manifestation of the cultural phase traditionally known as the Shell Mound Archaic.     

Reassessing the Emergence of Village Life in the Near East

This article reassesses the timing, context, and impetus for the onset of sedentary, complex hunter-gatherers, food production, and village life in the Near East during the Late Pleistocene and Early Holocene. Drawing on recent paleoclimatic and archaeological results, I argue that sedentism and then village life were rapid rather than gradual events that occurred during optimal climatic conditions and took place in resource-rich settings. These two social milestones included fundamental changes in economic strategies, social interaction, and ideology. Only by understanding the interplay between preexisting social institutions and human agency within communities prior to and during these periods of major social change will we be able to understand how and why food production began.     

Recent discoveries of Aurignacian and Epigravettian sites in Albania

Albania is a possible stepping-stone for the dispersal of Homo sapiens into Europe, since Palaeolithic traces (namely from the so-called Uluzzian culture) have been discovered in neighboring Greece and Italy. After two years of searching for evidence of modern humans in Albania we here report on excavated test trenches representing two time slices: an Aurignacian open-air site from southern Albania and two Epigravettian cave sites in central and northern Albania—areas heretofore archaeologically unknown. The new Albanian data fill a gap in the eastern Adriatic archaeological record for Marine Isotope Stages 3 and 2. Adding current knowledge of Late Pleistocene landscape evolution, a “contextual area model” can be constructed describing the habitats of these human populations.     

Applied geomorphology and archaeological survey strategy for sites of Pleistocene age: An example from Central Alaska

The development of a survey strategy for archaeological sites of Pleistocene age through the application of historical geomorphology is described. Geomorphic contexts in the northern foothills of the Alaska Range with potential for producing archaeological remains from the 30,000-12,000 bp interval were identified and subjected to exploratory testing. Contexts were selected on the basis of estimated age, palaeotopographic setting and geomorphic history, and included glaciofluvial outwash, side-valley fan alluvium, loessic colluvium and primary frozen loess. Testing was eventually focused on formerly deflated terrace surfaces—a potential source area for artifacts redeposited in the outwash or alluvium. Although the results of the exploratory testing were negative, and archaeological sites in the region remain confined to loess deposits of the later Late Glacial (12,000-10,000 bp), discoveries in other parts of Beringia suggest that sites of earlier Late Glacial age (14,000-12,000 bp) are also likely to be present in the foothills. The application of historical geomorphology in surveys for early prehistoric sites is essential for effective use of available resources and for maximizing the significance of the results (positive or negative).     

Archaeological Investigations in the Harbours of Burgaz,Turkey: 2011–2015 field seasons

Between 2011 and 2015 archaeological fieldwork was conducted in the Archaic through Late Antique harbours associated with Burgaz on the Datça Peninsula in south‐west Turkey. This work focused on survey and documentation of built features associated with the four harbours, limited stratigraphic excavation, and identification of shipwrecks and seafaring activity outside the harbours. The results offer new insights into the growth, expansion, and eventual abandonment of the port complex, its development alongside the urban settlement, and its changing maritime dynamics in light of economic shifts across the peninsula and the eastern Mediterranean.     

Paleochannel Studies in Archaeology: The Case of The Vychegda River,Northeastern European Russia

Geological and geomorphological settings are often taken into account when choosing strategy in archaeological studies. In the Vychegda River valley (Archangelsk Province, Komi Republic), at the end of the Late Pleistocene and in the Holocene, lateral channel migrations were the dominant process of riverine landscape changes and hence directly influenced human occupation of the valley. Therefore, to assess the physical settings of archaeological sites we employed paleochannel analysis, a geomorphological technique aimed at reconstructing river channel transformations in the historical and geological past. The potential application of paleochannel analysis in archaeology includes designing archaeological surveys and predicting destructive river actions at archaeological sites located in river valleys.     

The first record of palaeopathology from the zooarchaeological record of late Pleistocene,southwest Tasmania

Several bones from the Late Pleistocene archaeological site, Kutikina Cave, in southwest Tasmania, show pathological conditions. The majority of these specimens represent Bennett's or red‐necked wallaby (Macropus rufogriseus), with a single specimen of the Common wombat (Vombatus ursinus) recorded. While there has been extensive work in this region of Australia since the early 1980s, this is the first record of palaeopathology from the late Pleistocene of Tasmania, and the first from a human accumulation of predominately macropod material. The palaeopathology raises several questions concerning the mobility of these animals which might have increased their susceptibly to predation, while some of the effected elements are fragmented, suggesting that people utilised these bones despite their deformities.

Hunter-gatherer land use in Late Glacial south-east Italy

This paper is concerned with the Late Palaeolithic settlement of south-eastern Italy at the close of the Pleistocene. The Late Palaeolithic assemblages of the region have been studied previously from a rigid typological stance, with various schemes put forward suggesting evolution of the assemblages through different stages of an Epigravettian tradition, while the potential role of social and economic factors in shaping the various industries has been ignored. This paper shows how the Late Palaeolithic occupation of the region should be considered in relation to the former existence of an extensive coastal plain and to the sea-level rise which submerged it. Factors such as the availability of lithic raw material and the alternative strategies by which it was procured, the particular activities in which the tools were used and the role of the sites within a larger land use system were clearly crucial to assemblage composition.     

Emergent Complexity,Changing Landscapes,and Spheres of Interaction in Southeastern South America During the Middle and Late Holocene

Newly created academic programs at Brazilian universities have provided the impetus for new archaeological projects in southeastern South America during the last two decades. The new data are changing our views on emergent social complexity, natural and human-induced transformation of the landscape, and transcontinental expansions and cultural interactions across the Río de la Plata basin during the Middle and Late Holocene. We concentrate on six major archaeological traditions/regions: the Sambaquis, the Pantanal, the Constructores de Cerritos, the Tupiguarani, the Southern Proto-Jê, and the middle and lower Paraná River. Diverse and autonomous complex developments exhibit distinct built landscapes in a region previously thought of as marginal compared with cultural developments in the Andes or Mesoamerica. The trajectories toward increased sociopolitical complexity flourished in very different and changing environmental conditions. While some groups were pushed to wetland areas during a drier mid-Holocene, others took advantage of the more humid Late Holocene climate to intensively manage Araucaria forests. The start of the second millennium AD was a critical period marked by an increased number of archaeological sites, the construction of ceremonial architecture, and the intensification of landscape transformation; it also was marked by the rapid expansion of influences from outside the La Plata basin. The Amazonian Tupiguarani and Arawak newcomers brought with them significant changes in technologies and social and political structures, as well as novel landscape management practices.     

Did Modern Human Dispersal Take a Coastal Route into India? New Evidence from Palaeolithic Surveys of Kachchh,Gujarat

The Indian Ocean coastline is argued to have been a critical route of modern human dispersal from Africa, introducing Late Palaeolithic industries into South Asia, but a dearth of evidence has prevented a direct evaluation of this. Kachchh (Gujarat, India), located immediately east of the Indus Delta, is an important setting to appraise the Palaeolithic occupation of the western Indian coastline. Targeted survey of Late Pleistocene sediments there found widespread evidence for occupation of Kachchh during the Late Pleistocene: Middle Palaeolithic and possibly Late Acheulean lithic artifacts. The conspicuous absence of Late Palaeolithic industries in these Late Pleistocene deposits, with their presence only noted in Holocene contexts, does not support the model of modern human expansions into India with these industries via the coastal route. We evaluate these results in the context of current debates regarding Late Pleistocene hominin demography, adaptation, and expansions.     

The Early Development of Pastoralism in the Central Zagros Mountains

This paper explores the changes in early forms of pastoralism in the West Central Zagros Mountains from village-based herding in the Neolithic period to initial stages in the formation of full-fledged nomadic pastoralism by the Late Chalcolithic period. It has been argued that the initial development of pastoralism in the Central Zagros Mountains should be viewed as an adaptive strategy to a highland environment with limited and dispersed resources in order to supplement a primarily agricultural village-based economy. With expansion of the agricultural regime, the distance to be traveled to pastures by herders became greater, and as a consequence, the organization of labor involved in herding had to be modified to meet the more complex task of moving sizable herds over larger areas. The empirical evidence for the assessment of hypotheses proposed in this paper comes from archaeological fieldwork in the Islamabad Plain in the Zagros Mountains in western Iran, as well as previous archaeological and ethnographic research in the region.     

Demography and the Palaeolithic Archaeological Record

Demographic change has recently re-emerged as a key explanation for socio-cultural changes documented in the prehistoric archaeological record. While the majority of studies of Pleistocene demography have been conducted by geneticists, the archaeological records of the Palaeolithic should not be ignored as a source of data on past population trends. This paper forms both a comprehensive synthesis and the first critical review of current archaeological research into Palaeolithic demography. Within prevailing archaeological frameworks of dual inheritance theory and human behavioural ecology, I review the ways in which demographic change has been used as an explanatory concept within Palaeolithic archaeology. I identify and discuss three main research areas which have benefitted from a demographic approach to socio-cultural change: (1) technological stasis in the Lower Palaeolithic, (2) the Neanderthal-Homo sapiens transition in Europe and (3) the emergence of behavioural modernity. I then address the ways in which palaeodemographic methods have been applied to Palaeolithic datasets, considering both general methodological concerns and the challenges specific to this time period. Finally, I discuss the ability of ethnographic analogy to aid research into Palaeolithic demography.     

The History of African Village Chickens: an Archaeological and Molecular Perspective

The history of the introduction and dispersal of village chickens across the African continent is a subject of intense debate and speculation among scholars. Here, we synthesize and summarise the current scientific genetic and nongenetic knowledge in relation to the history of the species on the continent. Sociocultural, linguistic, archaeological and historic data all suggest a complex history for the species in Africa, characterized by multiple maritime and/or terrestrial introductions over time and several dispersal routes towards and within Africa. Molecular genetics information supports these observations and in addition suggests possible Asian centers of origin for African domestic chickens, including South Asia and Island Southeast Asia. However, both sets of data were until now too limited in their geographic scope, both within Africa and in comparison with chickens from Asia, to unravel the history of the species in detail. We anticipate that further continent-wide studies combining archaeological, ancient and/or modern genetic information may shed new insights on the history of the species. These will contribute to a deeper understanding of the history of trading networks and human interactions within Africa and between African and Asian societies, at the root of the development and expansion of African civilizations.     

AMS C dating of early human occupation of southern South America

The time of appearance of a persistent and demographically-viable hunter-gatherer population in late Pleistocene southern South America must be determined by evaluating evidence from as large as possible a sample of candidate archaeological sites in the region. We co-ordinated the AMS dating of multiple bone and charcoal samples from previously-excavated strata at the following sites: Arroyo Seco 2, Paso Otero 5, Piedra Museo, and Cueva Tres Tetas (all in Argentina), and Cueva del Lago Sofia 1 and Tres Arroyos (both in Chile). With one possible exception, we did not obtain new results to confirm earlier observations of pre-Clovis-age cultural activity at any of the sites considered in this study. The possible exception, Arroyo Seco 2, is considered in detail elsewhere [Politis G., Gutierrez M.A., Scabuzzo, C. (Eds), in press. Estado actual de las Investigaciones en el sitio 2 de Arroyo Seco (región pampeana, Argentina). Serie Monográfica INCUAPA 5. Olavarría]. However, our results for the samples which were the most preferred indicators of cultural events (hearth charcoal and cut-marked bone) confirm that people were in the southern cone of South America at or soon after 11,000 BP (13,000 cal BP). Considered alongside recent age estimates for the Clovis culture in North America, these results imply the contemporaneous emergence of a consistent and archaeologically-robust human occupation signal at widely-separated locations across the Western Hemisphere. Such findings suggest that Palaeoindian demic expansion may have involved more than one terminal Pleistocene dispersal episode.     

Computed femur and tibia volumes and cranial capacity under near-optimal conditions of skeletal growth: Relation to geomagnetic dipole field intensity and other latitude-dependent climatic variables in archaeological North America and North Africa

Using computed femur (F) and tibia (T) volumes and cranial capacity (CC), the Pleistocene geomagnetic acromegalosis (PGMA) model of human evolution is tested in eight series of male skeleton sets (n = 123) from aboriginal North America and North Africa, the majority dated to the Holocene. The material was selected from the extensive multiracial osteometric data base previously assembled in the course of adult residual rickets (RR) skeletal plasticity research in archaeological populations of the Northern Hemisphere, controlling for optimal bone eutrophism, that is, for the absence of sunshine and calcium deficits and demographic stress. Six of the eight series are of hunter-gatherers, including a terminal Pleistocene mesolithic sample from the Maghreb. As predicted by PGMA, a clear osteotrophic response is observed between the F, T, and CC of these populations and their geomagnetic dipole field intensity (GMFI) backgrounds, here expressed in microteslas (μT); along with evidence that the GMFI-dependent osteotrophism is stronger near the sagittal plane. Slightly higher bioenvironmental correlations, also compatible with PGMA, are obtained with a composite environmental osteotrophism parameter (CEOT.J), which incorporates the reciprocal of the archaeological site's reconstructed mean July temperature as a synergizer of GMFI. In a final demonstration of the utility of the new computed osteovolumetrics, it is shown that Skhul IV, to judge from its size and proportions, is a hyperrobust pre-neanderthal male skeleton of early Late Pleistocene interglacial age, and belongs to the North African geographical race.     

Late Pleistocene marine birds from southern Peru: distinguishing human capture from El Niño-induced windfall

The Central Andean hyperarid littoral has abundant marine fauna that would have been attractive to the earliest inhabitants. Whether people hunted or scavenged marine animals during the terminal Late Pleistocene have social and technological implications for understanding ancient Andean foraging. The periodic phenomenon of El Niño/Southern Oscillation (ENSO) disrupts marine food chains and results in the death of significant numbers of marine vertebrates and microorganisms. The onset of ancient El Niño events may have created a subsistence opportunity for human coastal inhabitants along the Pacific coast of the Central Andes when large numbers of guano-producing birds (cormorants, boobies, and pelicans) became weak and eventually died. The remains of numerous marine birds dominate the Late Pleistocene archaeological site of Quebrada Tacahuay in far southern Peru. This Terminal Pleistocene occupation dating to 10,770–10,290 years ago (uncalibrated radiocarbon years; 12,880–11,970 calendar years ago) was buried and sealed by an apparent ancient El Niño-induced debris flow. Using characteristics of the faunal assemblage I assess whether people hunted marine birds or ENSO created a subsistence opportunity for people to either scavenge a catastrophic assemblage or collect a community of vulnerable birds prior to the debris flow. I present avian skeletal part frequencies, butchering patterns, and the quantities and variety of marine bony fishes. An analysis of vertebrate taxonomic and skeletal composition in conjunction with an analysis of site context does not support the hypothesis that paleoenvironmental conditions generated an opportunity for the facile collection of either dead or weak birds. In contrast, the faunal data suggest that humans actively hunted, captured, and consumed healthy marine birds. When evaluating the possible role of environmental fluctuations on human behavior and diet, researchers must consider not only the taphonomy of the most abundant remains, but also how other vertebrate taxa in a region are affected as well as the archaeological context.     

Deglaciation and Human Colonization of Northern Europe

Few places worldwide experienced Late Glacial ecological shifts as drastic as those seen in the areas covered by, or adjacent to, the massive ice sheets that blanketed much of the northern hemisphere. Among the most heavily glaciated regions, northern Europe underwent substantial ecological shifts during and after the Last Glacial Maximum. The climatically unstable Pleistocene–Holocene transition repeatedly transformed far-northern Europe, placing it among the last regions to be colonized by Paleolithic societies. As such, it shares paleoenvironmental and archaeological analogues with other once glaciated areas where human populations, entrenched in periglacial environments prior to glacier retreat, spread into newly deglaciated territories. Perhaps most significant for northern Europeans were post-glacial effects of the Younger Dryas and Preboreal periods, as shifts in climate, plant, and animal communities elicited several adaptive responses including innovation, exploration, and the eventual settlement of once glaciated landscapes. This paper is a detailed review of existing archaeological and paleoecological evidence pertaining to the Late Upper Paleolithic of northern Europe, and offers theoretical observations on human colonization models and ecological responses to large-scale stadial and interstadial events.     

Local diversity in settlement,demography and subsistence across the southern Indian Neolithic-Iron Age transition: site growth and abandonment at Sanganakallu-Kupgal

The Southern Indian Neolithic-Iron Age transition demonstrates considerable regional variability in settlement location, density, and size. While researchers have shown that the region around the Tungabhadra and Krishna River basins displays significant subsistence and demographic continuity, and intensification, from the Neolithic into the Iron Age ca. 1200 cal. BC, archaeological and chronometric records in the Sanganakallu region point to hilltop village expansion during the Late Neolithic and ‘Megalithic’ transition period (ca. 1400–1200 cal. BC) prior to apparent abandonment ca. 1200 cal. BC, with little evidence for the introduction of iron technology into the region. We suggest that the difference in these settlement histories is a result of differential access to stable water resources during a period of weakening and fluctuating monsoon across a generally arid landscape. Here, we describe well-dated, integrated chronological, archaeobotanical, archaeozoological and archaeological survey datasets from the Sanganakallu-Kupgal site complex that together demonstrate an intensification of settlement, subsistence and craft production on local hilltops prior to almost complete abandonment ca. 1200 cal. BC. Although the southern Deccan region as a whole may have witnessed demographic increase, as well as subsistence and cultural continuity, at this time, this broader pattern of continuity and resilience is punctuated by local examples of abandonment and mobility driven by an increasing practical and political concern with water.
