Modern humans in Sarawak,Malaysian Borneo,during Oxygen Isotope Stage 3: palaeoenvironmental evidence from the Great Cave of Niah

During recent reinvestigations in the Great Cave of Niah in Borneo, the ‘Hell Trench’ sedimentary sequence seen by earlier excavators was re-exposed. Early excavations here yielded the earliest anatomically-modern human remains in island Southeast Asia. Calibrated radiocarbon dates, pollen, algal microfossils, palynofacies, granulometry and geochemistry of the ‘Hell Trench’ sequence provide information about environmental and vegetational changes, elements of geomorphic history and information about human activity. The ‘Hell’ sediments were laid down episodically in an ephemeral stream or pool. The pollen suggests cyclically changing vegetation with forest habitats alternating with more open environments; indicating that phases with both temperatures and precipitation reduced compared with the present. These events can be correlated with global climate change sequences to produce a provisional dating framework. During some forest phases, high counts of Justicia, a plant which today colonises recently burnt forest areas, point to fire in the landscape. This may be evidence for biomass burning by humans, presumably to maintain forest-edge habitats. There is evidence from palynofacies for fire on the cave floor in the ‘Hell’ area. Since the area sampled is beyond the limit of plant growth, this is evidence for human activity. The first such evidence is during an episode with significant grassland indicators, suggesting that people may have reached the site during a climatic phase characterised by relatively open habitats ∼50 ka. Thereafter, people were able to maintain a relatively consistent presence at Niah. The human use of the ‘Hell’ area seems to have intensified through time, probably because changes in the local hydrological regime made the area dryer and more suitable for human use.     

PALAEOCLIMATIC IDENTIFICATION BASED ON AN ISOTOPE STUDY OF TRAVERTINE FROM THE COPPER AGE SITE AT LOS MILLARES,SOUTH-EASTERN SPAIN*

Remains of an aqueduct from the Copper Age settlement of Los Millares have been studied. The isotope results (—7‰ < δ¹⁸O — 5.3‰) show that the aqueduct was used to transport fresh water at room temperature. The results are inconsistent with the aqueduct being used for hot water transport or as a container for water exposed to evaporation processes. Both isotopic and mineralogical results were useful in identifying the origin and use of building materials and also in determining climatic conditions during the time of the settlement occupation.     

An 8000-year history of landscape,climate, and copper exploitation in the Middle East: the Wadi Faynan and the Wadi Dana National Reserve in southern Jordan

Investigations of geomorphology, geoarchaeology, pollen, palynofacies, and charcoal indicate the comparative scales and significance of palaeoenvironmental changes throughout the Holocene at the junction between the hyper-arid hot Wadi 'Arabah desert and the front of the Mediterranean-belt Mountains of Edom in southern Jordan through a series of climatic changes and episodes of intense mining and smelting of copper ores. Early Holocene alluviation followed the impact of Neolithic grazers but climate drove fluvial geomorphic change in the Late Holocene, with a major arid episode corresponding chronologically with the ‘Little Ice Age’ causing widespread alluviation. The harvesting of wood for charcoal may have been sufficiently intense and widespread to affect the capacity of intensively harvested tree species to respond to a period of greater precipitation deduced for the Roman–Byzantine period – a property that affects both taphonomic and biogeographical bases for the interpretation of palynological evidence from arid-lands with substantial industrial histories. Studies of palynofacies have provided a record of human and climatic causes of soil erosion, and the changing intensity of the use of fire over time. The patterns of vegetational, climatic change and geomorphic changes are set out for this area for the last 8000 years.     

Reindeer Hunting in the Upper Palaeolithic: Sex Ratios as a Reflection of Different Procurement Strategies

This paper is a first attempt to investigate the variability in reindeer-procurement strategies in Upper Palaeolithic sites by means of sex ratios, as reflected by osteometrical data. For this purpose the “Variability Size Index” method is employed. The idea behind the analysis is that sex ratios in reindeer (but also in red deer and in bovids) were mainly determined—as they are in modern populations—by the reproductive biology of the animals and not by environmental conditions. Thus, any deviations from these ratios must be explained in terms of behavioural/cultural variables. The faunal material for the study comes from sites in southwest France, Switzerland and southern Germany. During the Upper Palaeolithic females dominate in all assemblages, but a clear variability can be seen: some sites show sex ratios similar to those found in Palaeolithic carnivore dens, whereas other sites show somewhat higher frequencies of bulls. The variation in the sex ratios of reindeer among Upper Palaeolithic sites cannot be explained by either their chronological position or topographical location, but it is more probably a result from seasonal differences in reindeer-procurement. Thus generalizations about the exploitation of reindeer or other prey species based on results of a single site or layer of a site will mask the variability in the subsistence strategies which existed either during the Upper Palaeolithic or, at a finer scale, even during the Magdalenian.     

Holocene Elevated Sea Levels on the North Coast of Vietnam

We present evidence of elevated Holocene sea levels on the north coast of Vietnam, comprising radiocarbon dating of raised coastal geomorphological and palaeobiological features at localities on the margins of the Bac Bo (Red River) Plain. This evidence indicates that by ca. 5500 cal yr B.P. mid‐tide lay approximately 5.4 m above national datum, that is 3.25 m above present local mid‐tide. By c. 3500 cal yr B.P., sea level was lowering and, by ca. 2000 cal yr B.P., mid‐tide lay at or above 1.5 m above present local mid‐tide. It is not yet possible to infer patterns of sea‐level fluctuation other than an overall lowering of elevation, although the separation of the raised and modern erosion notches does suggest two dominant mid to late Holocene periods of erosion — probably periods of sea‐level still‐stand or relatively slow sea‐level change. The intervening period of relatively rapid sea‐level change and associated reduced erosion probably dates to after ca. 2000 cal yr B.P..     

鬼方:殷周时代北方的农牧混合族群

本文认为鬼方是殷周时代北方的农牧混合族 群,不是如后世匈奴那样的骑马游牧族群。在山陕北部发现的 鬼族考古遗存可以证明这一点。自鬼族之后,战国匈奴出现之 前,在山陕北部也没有真正意义上的骑马游牧民族。自新石器 时代始,今山陕北部长期以来是原始农业的分布地区,后因气 候变化,逐渐演变为半农半牧地区,遂以这种形式长期与晋南 的农业区相对峙,其间出现比较稳定的半农半牧地区与纯农 区的分界线,即后来司马迁所说的龙门——碣石线。     

Spatial and Temporal Variation in Mesopotamian Agricultural Practices in the Khabur Basin,Syrian Jazira

While archaeologists have long recognized the value of regional analysis to define economic systems, relatively few archaeological data sets—principally settlement patterns, ceramics and lithics—have been used to assess regional-scale spatial variation and temporal change. As with other archaeological data sets, resolution of archaeobotanical data at a regional scale poses some formidable challenges. A new approach in the Near East uses archaeobotanical remains from multiple sites. The data have been drawn from midden assemblages that exhibit high variability between assemblages, requiring the use of random effects logistic regression models that can accommodate high variability. Our approach detects changes over time and over geographical region and tests the statistical significance of these changes. Results show a significant rise in crop-processing wastes, most probably from a specialized focus on barley processing at settlement and storage sites during the 3rd millenniumbc (Ninevite 5 and Early Jazira Periods). This shift to a greater representation of barley-processing by-products represented in middens can most probably be linked with an emerging specialization in pastoral production and re-settlement in arid regions of the northern Mesopotamian steppe in the 3rd millennium bc.     

Climate change during the Iron Age in the Shashe-Limpopo Basin,southern Africa

Recent research refines previous interpretations about the role of climatic factors in the development of Mapungubwe. First, the Medieval Warm Epoch started at about AD 1000, rather than 900. At about AD 900, Zhizo people moved into the Shashe-Limpopo Basin, most likely to hunt elephants for the East Coast trade. Secondly, a dry period at about AD 1200–1250 affected farming societies over a wide area. In the Basin, multiple rainmaking episodes occurred at this time. A similar situation took place around Makapansgat and at Great Zimbabwe. Thirdly, Mapungubwe was probably abandoned in AD 1300 because of cooler and drier conditions. At this time, it would have been impossible to maintain floodplain agriculture at the intensity necessary to support the large population. Agricultural failures probably undermined political authority, contributing to Mapungubwe's abandonment and shift in power to Great Zimbabwe. This detailed sequence challenges the re-calibrated climatic series from Makapansgat.     

A Physical-Geographic Regionalization of the Democratic Republic of Vietnam

The author served as a consultant in 1963–64 with a geography group of the State Committee of Sciences of North Vietnam that compiled a physical regionalization of the country. The regionalization, at 1:1,000,000 to 1:2,000,000, was based mainly on geologic-geomorphic and climatic criteria as well as other, more variable components of the physical environment. Six natural oblasts were distinguished: (1) the Northeast hills and low mountains, with a relatively cool climate, (2) the Northwest, distinguished by linear mountain ranges trending NW—SE, (3) the Truong Son, or Annamese Cordillera, (4) the Bac Bo [Tonkin] plain, the population center and economic core of North Vietnam, (5) the Thanh-Nghe coastal plains, and (6) the Binh-Tri-Thien coastal plains, in the extreme south. The oblasts were further partitioned into suboblasts, 51 rayons and 50 subrayons.     

On the tracks of the earliest dinosaurs: implications for the hypothesis of dinosaurian monophyly

From the record of dinosaurian skeletal remains it has been inferred that the origin and initial diversification of dinosaurs were rapid events, occupying an interval of about 5 million years in the Late Triassic. By contrast numerous reports of dinosauroid tracks imply that the emergence of dinosaurs was a more protracted affair extending through much of the Early and Middle Triassic. This study finds no convincing evidence of dinosaur tracks before the late Ladinian. Each of the three dinosaurian clades — Theropoda, Sauropodomorpha, Ornithischia — produced a unique track morphotype that appears to be an independent modification of the chirotherioid pattern attributed to stem-group archosaurs (thecodontian reptiles). The existence of three divergent track morphotypes is consistent with the concept of dinosaurian polyphyly but can be reconciled with the hypothesis of dinosaurian monophyly only by invoking many and rapid reversals in the locomotor anatomy of early dinosaurs. The origin of dinosaurs was not the correlate or consequence of any single event or process, be it global change, competitive replacement, or opportunism in the wake of mass extinction. Instead the origin of dinosaurs is envisaged as a series of three cladogenetic events over an interval of at least 10 million years and possibly as much as 25 million years. This scenario of dinosaurian polyphyly is as well-supported by fossil evidence as is the currently favoured view of dinosaurian monophyly.     

Environmental Conditions of The Late Paleolithic and Early Neolithic Sites in Southern Sakhalin

The article presents the results of a palynological study conducted at Late Paleolithic (Olympiya-5 and Ogonki-5) and Early Neolithic (Slavnaya-5) sites located in the southern part of Sakhalin Island. The reconstructed environments оf Late Paleolithic sites in southern Sakhalin included dark coniferous (fir and spruce) forests, indicative of a relatively warm phases of the last stadial coinciding with Daansgard-Oeschger oscillations. The Early Holocene conditions in southern Sakhalin were relatively warm although a virtually complete absence of pollen of deciduous trees suggests that the Boreal period was not the Holocene climatic optimum in that region.     

ESR Dating of the Last Interglacial Mousterian at Karaïn Cave, Southern Turkey

We have obtained ESR ages on 18 teeth from archaeological levels AH16-AH27 exposed at the east profile in compartment E at Karaïn Cave. This sequence exhibits a transition in lithic assemblage from a Classic Charentian to a Karaïn (Zagros-type) Mousterian between levels AH27 and AH25, and two calcite-cemented soils at levels AH22 and AH16 which have been interpreted as climatic warm phases. Since we found no systematic increase in tooth ages with depth, we assigned this sequence a mean early uptake (EU) age of 108 ± 23 ka and mean linear uptake (LU) age of 121 ± 27 ka, on the basis of 37 subsamples from 16 teeth. In this site, the precision of individual tooth ages suffered little from the problems associated with uranium uptake. However, this advantage was offset due to uncertainties arising from the rather inhomogeneous nature of the enclosing strata which contained various sizes of limestone blocks with intervening sediment. This led to difficulties in ascribing a precise annual gamma radiation dose to individual teeth in such a "lumpy" gamma radiation field. Considerable scattering of the individual tooth ages occurred mainly because the annual gamma dose comprised greater than 50% of the total annual dose to the individual teeth. On the basis of the ESR dating results, we infer that deposition of the two different lithic assemblages and both the penultimate and the final climatic warm phases at Karaïn probably occurred during oxygen isotope stage 5. We also conclude that these lithic assemblages are significantly different than contemporaneous Levantine Mousterian industries which occur about 700 km to the southeast.     

Mid- to late-Holocene vegetational and land-use change in the Hadrian's Wall region: a radiocarbon-dated pollen sequence from Crag Lough,Northumberland, England

Pollen, charcoal and sedimentological analyses of a radiocarbon-dated sediment sequence from Crag Lough, by Hadrian's Wall, northern England, are used to reconstruct vegetational and land-use change since ca. 3000 cal BC. Clearance of Quercus and Corylus avellana woodland began at ca. 2600 cal BC, followed by a substantial decline of Alnus glutinosa and spread of Calluna vulgaris at ca. 400 cal BC. Local cereal cultivation occurred sporadically from ca. 2200 cal BC, with a decline (perhaps associated with climatic deterioration) at ca. 900 cal BC, then an increase at ca. 600 cal BC. Secale cereale was grown in the area from approximately the first to fifth centuries AD, followed by a second phase from ca. AD 1250–1700, when it was accompanied by Cannabis sativa.The sequence is interpreted in the light of the archaeological record, particularly in relation to the impact of Roman military activity in the area. The most significant episodes of woodland clearance occurred in the late Neolithic/early Bronze Age period and then in the middle Iron Age, creating a patchwork of woodland, heather moorland, pasture and arable land by the Roman period. The main changes in the Roman period were a decline in the extent of Betula woodland and perhaps the local introduction of Secale cereale cultivation. Local land management practices involving fire seem to have been suspended in the Roman period, but resumed afterwards. The end of the Roman period may have been accompanied by a shift towards pastoral land-use and abandonment of less favourable agricultural land, but the effect was minor compared to that at other sites in the region. Later shifts in land use may relate to climate variability, as reconstructed from several mires in northern England.     

Phylogeographic analysis of barley DNA as evidence for the spread of Neolithic agriculture through Europe

Results of analyses of the photoperiod response gene (PPD-H1) and simple sequence repeats (SSRs) in modern landraces of cultivated barley were used as evidence for the mechanism of agricultural spread in Neolithic Europe. In particular, we explored the usefulness of considering adaptive genes as indicators of past selective pressures acting on crops, during their spread through Europe. In some areas, such as the Alpine region, Britain and Scandinavia, we have evidence to suggest that the adaptation of crops to certain climatic conditions may have contributed to the timing of agricultural spread. At the northern fringes of Europe, and in higher altitude locations in central Europe, the introduction of more suitably adapted cereals may have facilitated successful agriculture to trigger agricultural expansion. This research opens up the possibility of investigating other genetic adaptations to climate, which would permit a fuller evaluation of the relative contributions of climate/crop and forager/farmer interactions in the process of agricultural spread.     

The Timing of Angel Mounds Palisade Construction A Search for the Best Chronological Model

Abstract

Angel Mounds was a heavily fortified Mississippian settlement with several discrete palisades. Although the palisades were identified early on, the construction sequence has remained elusive because the construction episodes do not have stratigraphic relationships with one another. Recent work at the site reexamined old test excavations and collected new material for radiocarbon dating. AMS dating yielded a suite of new dates from palisade contexts. To refine the construction sequence, five Bayesian chronological models were constructed for palisade building. These models indicate that palisades were first built at Angel Mounds sometime between A.D. 1278 and A.D. 1410, which precedes or coincides with regional depopulation in the lower Ohio River valley. These results further indicate that palisade building at Angel Mounds may be a consequence of external competition and conflict caused by resource-induced stress resulting from deteriorating climatic conditions.     

Fair weather electric field in Port Moresby

Measurement of the fair weather electric field at Port Moresby during the dry season in July–August 1988 shows no clear effect of the world-wide thunderstorm activity predicted by Mauchlyy S. J. (1923, J. geophys. Res. 28, 61). The observed field is generally low—approximately, 60V/m—during daytime but remains relatively higher—about 150 V/m—at night. The field strength increases slowly after sunset but decreases sharply after sunrise. The levels observed are typical of isolated sites and the frequent temperature inversion observed during the period is suggested as the likely explanation of the observed behaviour of the field.     

Persistent land use patterns and the mid-Holocene housepits of Wyoming

Abstract

The cyclical use of sites and locales over decades, centuries, and even millennia is an important aspect of hunter-gatherer land use that is rarely considered in studies that focus on a single annual cycle. The long-term perspective provided by archaeological data can be used to delineate persistent land use patterns and contribute to an understanding of the complexity of hunter-gatherer behavior. Mid-Holocene Wyoming housepit data document persistent land use over at least a 2000-year period at three spatial scales—the reuse of housepits, reuse of sites containing housepits, and use of different sites within the larger region. Slab-lined cylindrical basins at many sites in southwest Wyoming provide evidence for stable long-term land use during the middle Holocene. The focal point of this pattern was probably a predictable resource, possibly some type of root plant that would have been available during the dry middle Holocene.     

Population growth,climatic cooling,and the development of collector strategies on the Southern Plateau,western North America

A change in human adaptations on the Southern Plateau during the fourth millennium B.P offers the opportunity to investigate the process by which immediate-consumption strategies are replaced by delayed consumption strategies among hunter-gatherers. Assemblage structure and settlement pattern are used to infer the nature of resource acquisition strategies between 2000 and 6000 radiocarbon years B.P., and the results are compared with a proxy record of population and a detailed reconstruction of terrestrial and riverine paleoenvironments. Results show that a strategy of mobile and later occasionally sedentary foraging with little use of storage technology persisted until as late as 3500 B.P and was abruptly and without detectable gradation replaced by a strictly scheduled, semisedentary, logistically organized, storage-dependent collector strategy. The change took place at a time of depressed population and 400 years after a period of climatic cooling had begun, thus eliminating both demographic pressure and environmental determinism as explanations. The evidence could be explained by prolonged selective pressure of an increasingly seasonal environment acting on successively attempted behavioral variants, but the widespread rise of collector-like strategies throughout the west at about the same time leaves open the question of exogenous development and highlights the importance of climatic change.     

Manuring and stable nitrogen isotope ratios in cereals and pulses: towards a new archaeobotanical approach to the inference of land use and dietary practices

This paper explores the impact of animal manure application on the δ¹⁵N values of a broad range of crops (cereals and pulses), under a range of manuring levels/regimes and at a series of locations extending from northwest Europe to the eastern Mediterranean. We included both agricultural field experiments and areas where ‘traditional’ farming is practised. Our aim is to ground-truth interpretation of δ¹⁵N values in archaeobotanical crop remains as evidence of past growing conditions and husbandry practices. The results confirm the potentially radical impact of manuring on δ¹⁵N values in cereals, depending on manuring level, but indicate only a slight effect on pulses, which can fix atmospheric nitrogen. The expected geographical trend towards greater δ¹⁵N with increasing climatic aridity is not apparent, probably because the growing conditions for crops are ‘buffered’ through crop management. Each of these observations has fundamental implications for archaeobotanical interpretation of δ¹⁵N values as evidence of land use practices and (together with analysis of bone collagen/tooth enamel in potential consumers) palaeodiet.     

Another Look at Lerna: An EH IIB Trading Post?

The Early Helladic IIB sealings from Lerna have rarely been considered as functional documents even though they are often called as evidence for EH II economic complexity, for elite control of resources or even for ‘central place’ redistribution. Close analysis of the sealings, however, casts doubt on whether the documents support these economic or social interpretations, seeming rather to point to the grafting of a foreign system of resource management onto a less developed society. After examining the specific functions of the sealings —‘who did what?’— we consider their implications for social organization. This evidence is then linked to the wider picture: a whole range of new sealing practices as well as the striking innovations in architecture and construction which appear at much the same time. We conclude that these developments are largely due to the arrival of foreign (probably Anatolian) traders at Lerna early in EH IIB.
