Warriors from the south? Arrowheads from the Tollense Valley and Central Europe
Leif Inselmann et al.
Antiquity, forthcoming
Abstract:
Investigations in the Tollense Valley in north-eastern Germany have provided evidence of a large and violent conflict in the thirteenth century BC. Typological analysis of arrowheads from the valley (10 flint and 54 bronze specimens) and comparison with type distributions in Central Europe, presented here for the first time, emphasise the supra-regional nature of the conflict. While the flint arrowheads are typical for the local Nordic Bronze Age, the bronze arrowheads show a mixture of local and non-local forms, adding to the growing evidence for a clash between local groups and at least one incoming group from southern Central Europe.
Tracing social disruptions over time using radiocarbon datasets: Copper and Early Bronze Ages in Southeast Iberia
Rafael Micó et al.
Journal of Archaeological Science: Reports, October 2024
Abstract:
The transition between the Late Copper and the Early Bronze Age in Central and Western Europe saw large-scale social disruptions ca. 2200 cal BCE (’4,2 ka event’). Their source is much debated, and scholars have addressed the problem from various disciplinary perspectives. One account points to the westward migration of populations with Pontic-Caspian ‘Steppe’ ancestry, possibly favoured by the spread of infectious diseases, but the question remains open. In southeast Iberia, the shift from communal burial practices in the Copper Age to single and double tombs in the Bronze Age offers a reliable diagnostic feature for the transition. To investigate social and demographic changes in this region during the late 3rd millennium BCE, we resorted to new C14 dates from human bone samples originating from both kinds of funerary contexts. Our statistical analysis indicates that most probably the changes in funerary rituals in southeast Iberia were fast. It also implies that the local populations had dropped in numbers before 2200 cal BCE, so that the presence of ‘Steppe ancestry’ ca. 2200–2000 cal BCE could be the result of their admixture with neighbouring peoples. Finally, we suggest that more high-precision C14 dates and archaeogenetic analyses from this transitional period are crucial for addressing the formation of Bronze Age societies.
Bronze Age cheese reveals human-Lactobacillus interactions over evolutionary history
Yichen Liu et al.
Cell, forthcoming
Abstract:
Despite the long history of consumption of fermented dairy, little is known about how the fermented microbes were utilized and evolved over human history. Here, by retrieving ancient DNA of Bronze Age kefir cheese (∼3,500 years ago) from the Xiaohe cemetery, we explored past human-microbial interactions. Although it was previously suggested that kefir was spread from the Northern Caucasus to Europe and other regions, we found an additional spreading route of kefir from Xinjiang to inland East Asia. Over evolutionary history, the East Asian strains gained multiple gene clusters with defensive roles against environmental stressors, which can be a result of the adaptation of Lactobacillus strains to various environmental niches and human selection. Overall, our results highlight the role of past human activities in shaping the evolution of human-related microbes, and such insights can, in turn, provide a better understanding of past human behaviors.
The costs of transporting goods by different modes: A case study of pottery movement in late Roman Britain
Rob Wiseman, Scott Ortman & Olivia Bulik
Journal of Archaeological Science, October 2024
Abstract:
There is a long-standing view that, in the Roman world, transport by sea and river was very much cheaper than by land. Previous analyses of transport costs have relied primarily on a few surviving historical records, notably the Edict on Maximum Prices issued by Diocletian in 301 CE. Here we outline an alternative method for deriving relative costs of transportation by different modes using materials recovered in archaeological excavations. We apply this to the distribution of Late Romano-British pottery (c. 250–400 CE) to calculate the cost ratios of transportation by road, river and sea to rural settlements and towns in lowland Britannia. The analysis suggests a best fit cost ratio of road to rivers and sea of 1:3:4 (i.e. transport by road was three times as costly as by river and four times that by sea), with 95% confidence interval of roads to rivers 1:1–5 and roads to sea of 1:1–9. These values are broadly consistent with transport cost ratios of 1:4:8 in England in the first half of the fourteenth century, when the country's transport network had reached a degree of integration comparable with late Roman Britain.
Linear Pottery Culture sites west of the Oder river in the Federal state of Brandenburg, Germany
Erwin Cziesla
Antiquity, forthcoming
Abstract:
After colonising the loess uplands of Bohemia, Moravia and Poland, c. 5500 cal BC, the earliest farming societies (LBK) spread northwest along the Oder valley; then expansion ended at Uckermark, where 119 findspots are located. Newly found sites indicate changes to housing and livestock-farming techniques, in particular the specialised production of dairy products.
