A wall or a road? A remote sensing-based investigation of fortifications on Rome's eastern frontier
Jesse Casana, David Goodman & Carolin Ferwerda
Antiquity, forthcoming
Abstract:
During a pioneering aerial survey of the Near East in the 1920s, Father Antoine Poidebard recorded hundreds of fortified military buildings that traced the eastern frontier of the Roman Empire. Based on their distribution, Poidebard proposed that these forts represented a line of defence against incursions from the east. Utilising declassified images from the CORONA and HEXAGON spy satellite programmes, the authors report on the identification of a further 396 forts widely distributed across the northern Fertile Crescent. The addition of these forts questions Poidebard's defensive frontier thesis and suggests instead that the structures played a role in facilitating the movement of people and goods across the Syrian steppe.
The causes and consequences of women's status in Himba pastoralists
Sean Prall & Brooke Scelza
Evolution and Human Behavior, forthcoming
Abstract:
Gender inequalities in status and prestige are common across many populations, but while considerable attention has been paid to understanding the drivers of men's status, the causes and consequences of women's status have received scant attention, particularly outside industrialized contexts. We combine demographic, health and dyadic rating data from an endogamous community to show that women of higher status have improved outcomes for themselves and their children. We find perceptions of generosity, intelligence, and respectfulness best predict women's status. Women of greater status marry higher quality partners and have children with better growth outcomes, results similar to those found for men across cultures, but rarely demonstrated in women. The results suggest women's status can be an important driver of fitness-related outcomes, and should be considered alongside men's status in evolutionary studies.
Multiproxy analysis of Upper Palaeolithic lustrous gravels supports their anthropogenic use
Lila Geis et al.
PLoS ONE, November 2023
Abstract:
Upper Palaeolithic sites in southwestern France attributed to the Upper Gravettian and the Solutrean yielded sub spherical gravels with a highly shiny appearance that have intrigued researchers since the 1930s. In this work, we analyze specimens from five sites, including the recently excavated Solutrean site of Landry, to establish whether their presence in archaeological layers and peculiar aspect are due to natural processes or human agency. We study the spatial distribution of gravels at Landry and submit archaeological gravels from the five sites, natural formations, Landry sediment sieving, and polishing experiments with a rotary tumbling machine to morphometric, colorimetric, microscopic, and textural analyses. Our results indicate the lustrous gravels found at the five sites result from deliberate selection and suggest their shiny appearance is the consequence of human agency, possibly resulting from prolonged contact with a soft material such as animal skin. Ethnographic accounts indicate that these gravels may have been used for magico-religious ritual purposes (charms, sorcery, divination etc.), in games, as elements of musical instruments, and as items serving other social and personal purposes. We argue that these objects reflect a cultural innovation emerged during the Gravettian and continued into the Solutrean.
Convergence at Poverty Point: A revised chronology of the Late Archaic Lower Mississippi Valley
Seth Grooms, Grace Ward & Tristram Kidder
Antiquity, forthcoming
Abstract:
The Poverty Point site, located in the Lower Mississippi Valley of the south-eastern United States, is commonly considered a centre of innovation that exported new material culture, practices and identity to presumably contemporaneous sites in the region. Recent radiocarbon data, however, show that Jaketown, previously interpreted as a peripheral expression of Poverty Point culture, is earlier than the type-site. Using the revised chronology at Jaketown as a case study, the authors argue that assuming a radial diffusion of cultural innovations biases our understanding of social change and obfuscates complex histories. Their study demonstrates how examining local sequences can challenge generalised models of regional cultural change.
Plant-based red colouration of shell beads 15,000 years ago in Kebara Cave, Mount Carmel (Israel)
Laurent Davin, Ludovic Bellot-Gurlet & Julien Navas
PLoS ONE, October 2023
Abstract:
Decorating the living space, objects, body and clothes with colour is a widespread human practice. While the habitual use of red mineral pigments (such as iron-oxide, e.g., ochre) by anatomically modern humans started in Africa about 140,000 years ago, the earliest documentation of the use of organic plant or animal-based red pigments is known from only 6,000 years ago. Here, we report the oldest reliable evidence of organic red pigment use 15,000 years ago by the first sedentary hunter-gatherers in the Levant. SEM-EDS and Raman Spectroscopy analyses of 10 red-stained shell beads enabled us to detect and describe the use of a colourant made of Rubiaceae plants roots (Rubia spp., Asperula spp., Gallium spp.) to colour personal adornments from the Early Natufian of Kebara cave, Mount Carmel, Israel. This adds a previously unknown behavioural aspect of Natufian societies, namely a well-established tradition of non-dietary plant processing at the beginning of the sedentary lifestyle. Through a combined multidisciplinary approach, our study broadens the perspectives on the ornamental practices and the chaînes opératoires of pigmenting materials during a crucial period in human history.
Shark-tooth artefacts from middle Holocene Sulawesi
Michelle Langley et al.
Antiquity, forthcoming
Abstract:
Although first identified 120 years ago, knowledge of the Toalean technoculture of Middle Holocene Sulawesi, Indonesia, remains limited. Previous research has emphasised the exploitation of largely terrestrial resources by hunter-gatherers on the island. The recent recovery of two modified tiger shark teeth from the Maros-Pangkep karsts of South Sulawesi, however, offers new insights. The authors combine use-wear and residue analyses with ethnographic and experimental data to indicate the use of these artefacts as hafted blades within conflict and ritual contexts, revealing hitherto undocumented technological and social practices among Toalean hunter-gatherers. The results suggest these artefacts constitute some of the earliest archaeological evidence for the use of shark teeth in composite weapons.
Demographic dynamics between 5500 and 3500 calBP (3550–1550 BCE) in selected study regions of Central Europe and the role of regional climate influences
Ralph Großmann, Mara Weinelt & Johannes Müller
PLoS ONE, October 2023
Abstract:
With their rich Late Neolithic to Early Bronze Age archives, the Circumharz region, the Czech Republic/Lower Austria region, and the Northern Alpine Foreland are well-suited for research on potential links between human activities and climate fluctuations of this period with pronounced archaeological changes. In this paper, we reconstruct the rate and density of the available 14C data from 5500 to 3500 calBP (3550–1550 BCE). We ask to what extent population patterns varied over time and space, and whether fluctuations in human populations and their activities varied with local/regional climate changes. To answer these questions, we have compiled an extensive list of published radiocarbon dates and created 14C sum calibrations for each region. We also compare population dynamics with local and regional palaeoclimate records derived from high-resolution speleothems. At the regional scale, the results suggest a causal relationship between regional climate and population trends. Climate and associated environmental changes were thus at least partly responsible for demographic trends. These results also allow us to question the motivation for the construction of so-called “Early Bronze Age princely tombs” in the Circumharz region during a period of population decline. Among other things, it can be argued that the upper echelons of society may have benefited from trade relations. However, this process was accompanied by ecological stress, a cooling of the winter climate, a decline in the total population and an increase in social inequality.
