Vegetation changes and human action from the Neolithic to the Bronze Age (7000–4000 B.P.) in Alicante,Spain, based on charcoal analysis

Charcoal analysis reveals various palaeo-ecological phases from the Neolithic to the Bronze Age. Agriculture starts about 7000 B.P. in favourable ecological conditions. Most of the charcoal spectra from sites on the coast represent thermomediterranean holm-oak forest; those from the inland mountains represent mesome-diterranean holm-oak forest. The Neolithic I Impressed Ware people were the first to clear the forest to plant their crops. This clearance of primary woodland resulted in the development of secondary vegetation of pine woods or scrub. The scrub reached its maximum during the Bell Beaker phase and Bronze Age in the Cova de les Cendres. In the Neolithic II open air sites, the percentages of Quercus ilex/coccifera remain high. This may be the result of a different exploitation of the land, or suitable conditions for the growth and survival of the vegetation.     

Stable isotope evidence for the consumption of millet and other plants in Bronze Age Italy

Stable carbon and nitrogen isotope analysis was carried out on human and animal bones from four inland Early and Middle Bronze Age sites in Northern and Southern Italy. The main aims of the investigation were to explore the contribution of plant foods to the human diet and to examine any dietary differences between and within each of the sites. At two of the sites in Northern Italy, human and animal bones were significantly enriched in ¹³C. This finding was attributed to the consumption of domestic millets (Panicum miliaceum and/or Setaria italica), which are C₄ pathway plants. Conversely, individuals from the two Bronze Age sites in Southern Italy were significantly depleted in ¹³C compared to those from the north. Here, millet was absent from the diet, and protein from C₃ plants made a much greater dietary contribution than animal protein. This finding highlights the importance of cereal cultivation, most likely of wheat and barley, in the south of Italy during the Bronze Age. Overall, our results support the idea that the widespread cultivation of millet first occurred in Northern Italy, following its introduction from across the Alps in Central Europe. Finally, we found no significant differences in the stable isotope values between individuals at each site, when grouped by their sex or presence of grave goods. This leads to the conclusion that any status difference that may have existed is not reflected in the long‐term dietary record, or at least not as measurable by stable isotope analysis.

Mobility in Central European Late Eneolithic and Early Bronze Age: femoral cross-sectional geometry

Some scholars explain the absence of settlements in the Bohemian and Moravian Late Eneolithic (Corded Ware archaeological culture) as a consequence of pastoral subsistence with a high degree of mobility. However, recent archaeological studies argued that the archaeological record of the Late Eneolithic in Central Europe exhibits evidence for sedentary subsistence with mixed agriculture, similar to the subsequent Early Bronze Age. Because the archaeological data do not allow us to address unambiguously the mobility pattern in these periods, we used cross-sectional analysis of the femoral midshaft to test mobility directly on the human skeletal record. The results of femoral midshaft geometry do not support a high degree of mobility in the Late Eneolithic in Central Europe. This conclusion is supported mainly by no significant differences in male groups between the Late Eneolithic and Early Bronze Age in mechanical robusticity and shape of the femoral midshaft, although Corded Ware males still exhibit the highest absolute mean values of the diaphyseal shape (I(A-P)/I(M-L)) ratio and antero-posterior second moment of area. However, Late Eneolithic females have significantly higher torsional and overall bending rigidity because of a significantly higher medio-lateral second moment of area. This finding cannot be directly linked with a higher degree of long-distance mobility for these females. A significant difference was also found in overall decrease of size parameters of the femoral midshaft cross section for one of the Early Bronze Age samples, the Wieselburger females. Since the decrease of size and mechanical robusticity for Wieselburger females does not correspond with the parameters of Early Bronze Age females, we can expect a mosaic pattern of changes during the Late Eneolithic and Early Bronze Age period, instead of a simple unidirectional (diachronic) change of the mechanical environment.     

Secondary States in Perspective: An Integrated Approach to State Formation in the Prehistoric Aegean

In this article, we explore the typological distinction between primary and secondary states. We outline a methodology for exploring variability in the formation and organization of secondary states that integrates aspects of traditional neoevolutionary approaches, Marcus's "dynamic model," Blanton et al.'s "dual-processual model," and world-systems theory. We discuss the development of the Minoan and Mycenaean states of the Bronze Age Aegean and argue that they arose via different mechanisms of secondary state formation, through direct and indirect contact with neighboring societies in the Eastern Mediterranean, Near East, and Egypt. We argue that a model that measures state formation along several different theoretical dimensions encourages archaeological exploration of secondary states along varied historical trajectories, in different (pre)historic contexts.     

Urbanization within a Dynamic Environment: Modeling Bronze Age Communities in Upper Mesopotamia

Here agent-based models are employed to explore the behavior of small communities and their associated economic systems within an area of climatically marginal environment in northern Syria and Iraq. The examples, drawn from late prehistoric and Bronze Age societies that developed at the onset of urbanization, show how small communities might respond to various resource stresses and environmental fluctuations. The computer simulations demonstrate that some households gain resources at the expense of others and the community becomes more economically differentiated through time with some households benefiting at the expense of others. The approaches discussed demonstrate that complex societies were capable of a wide range of responses to stresses that could be absorbed or amplified via a number of social, economic, or demographic processes.     

The Early Bronze Age dendrochronology of Sovjan (Albania): A first tree-ring sequence of the 24th – 22nd c. BC for the southwestern Balkans

The archaeological site of Sovjan is situated on the edge of the Korçë Basin, southeastern Albania. Its remarkably long and well investigated stratigraphic sequence, spanning from the Neolithic till the Iron Age, makes it an important type- and reference-site for the whole region. At different periods of prehistory it was located on the shores of the former Lake Maliq that once filled the Korçë Basin, but was definitely drained in the 1940′s. These permanent wetland conditions on the site allowed for a high degree of preservation of organic material, especially wood. Based on the current knowledge, level 8 of Sovjan contains the best-preserved wooden material of all the Early Bronze Age sites in the Balkans. Through the combination of dendrochronology and Bayesian modelling, i.e. wiggle-matching, a floating 269-years long tree-ring chronology was constructed, with an absolute end-date range falling between 2158 and 2142 cal BC (2σ). It was possible to establish that the dwellings and the trackway associated with the last occupation phase of level 8 are contemporaneous. Additionally, with the help of the new dendrochronological data and based on previously published charcoal dates, the absolute chronology of the subsequent level 7 is being narrowed-down to a range from the mid-22nd to mid-20th c. cal BC (2σ). The Early Bronze Age layers of the archaeological site of Sovjan, which are particularly pertinent for the 3rd millennium chronology of the southwestern Balkans, can now be dated with high precision for the first time and hence offer a major chronological reference point in the region.

Brief communication: new evidence of tuberculosis from prehistoric Korea-Population movement and early evidence of tuberculosis in far East Asia

Tuberculosis has been recognized in Japan and Korea for more than 500 years in historical medical documents. However, the origin and early existence of tuberculosis is poorly understood in these regions. Very recently, skeletal evidence for tuberculosis from the Bronze Age (or Aneolithic) period was reported from Japan and Korea. This article describes a possible case of spinal tuberculosis from an archeological site in Korea, which was dated to the first century BC. This date corresponds to the Aneolithic (Yayoi) period in Japan. Skeletal evidence for tuberculosis during the Bronze Age period found in both Korea and Japan are, therefore, discussed as evidence of the earliest tuberculosis outbreaks in East Asia and as biological indicators of population movement between Korea and Japan during this period.     

Carthamus species in the ancient Near East and south-eastern Europe: archaeobotanical evidence for their distribution and use as a source of oil

We present an overview of archaeobotanical Carthamus spp. finds from Neolithic to medieval sites in the Near East and adjacent areas. A particular focus is put on the cultivated form of the genus. Safflower appears first in a number of early Bronze Age (3000 b.c.) sites in northern and central Syria. From there it apparently spread to Egypt, the Aegean and south-eastern Europe. The Near Eastern Bronze Age evidence shows a striking exclusiveness in the distribution patterns of safflower and flax, with flax being restricted to Levantine and Iranian sites. This may reflect the contrasting ecological requirements of the two crops, with safflower being well adapted to drought and salinity and thus to arid conditions. At the same time the geographically complementary evidence may indicate a similar use of the two crops and most probably suggests that the safflower was also used for oil almost from the beginning of its cultivation.
