Network approaches in archaeology offer a promising avenue for facilitating bottom-up, comparative approaches to sociopolitical organization. While recent applications have focused primarily on migration and demographic trends, identity and identity politics, and the dynamics of geopolitical and regional interaction, little in the way of comparative sociopolitical organization has been attempted. In this study, I present an alternative approach to the use of sociotypological models across southern Appalachia. In particular, I demonstrate the value in employing network analyses as a mode of formally and quantitatively comparing the relational structures and organizations of sociopolitical landscapes; in this case, those traditionally characterized as constellations of chiefdoms. By approaching southern Appalachian histories through the relationships upon which social, political, and economic institutions were actually built, I move the study of southeastern political systems beyond the use of models that emphasize the behaviors of elites and the ruling class as inspired by the ethnographic and ethnohistoric records. To these ends, using a robust regional ceramic dataset, I compare network histories and political landscapes for the southern Appalachian region between ca. AD 800 and 1650. The results of these analyses contribute insights to the study of small-scale political organizations by demonstrating that (i) as chiefdoms developed, leaders drew on preexisting social and political conditions; (ii) while networks of chiefly interaction were defined by instability, wider networks of interaction were much more durable; and (iii) quantitative network analyses and qualitative ethnohistoric accounts can articulate with one another to shed light on indigenous political organization.

Scythians are known from written sources as horse-riding nomadic peoples who dominated the Eurasian steppe throughout the Iron Age. However, their origins and the exact nature of their social organization remain debated. Three hypotheses prevail regarding their origins that can be summarized as a "western origin", an "eastern origin" and a "multi-regional origin". In this work, we first aimed to address the question of the familial and social organization of some Scythian groups (Scytho-Siberians) by testing genetic kinship and, second, to add new elements on their origins through phylogeographical analyses. Twenty-eight Scythian individuals from 5 archeological sites in the Tuva Republic (Russia) were analyzed using autosomal Short Tandem Repeats (STR), Y-STR and Y-SNP typing as well as whole mitochondrial (mtDNA) genome sequencing. Familial relationships were assessed using the Likelihood Ratio (LR) method. Thirteen of the 28 individuals tested were linked by first-degree relationships. When related, the individuals were buried together, except for one adult woman, buried separately from her mother and young sister. Y-chromosome analysis revealed a burial pattern linked to paternal lineages, with men bearing closely related Y-haplotypes buried on the same sites. Inversely, various mtDNA lineages can be found on each site. Y-chromosomal and mtDNA haplogroups were almost equally distributed between Western and Eastern Eurasian haplogroups. These results suggest that Siberian Scythians were organized in patrilocal and patrilineal societies with burial practices linked to both kinship and paternal lineages. It also appears that the group analyzed shared a greater genetic link with Asian populations than Western Scythians did.

Ethnography, Archaeology, Undergraduate Students, Graduate Students, Foreign Countries, Computer Networks, and Europe

Introduction: This study investigates the implications of the interplay of multiple information infrastructures to learning and conducting work and to its related information work practices, and how the materialities of work and its infrastructures play into their intermingling. Method: The present study is based on an ethnography of a week-long archaeological teaching excavation conducted by the author. The excavation took place on a stone-age site in a Nordic country in Spring 2016. Analysis: The analysis of the ethnographic data was based on constant comparative method and close reading. Results: Four major information infrastructures were identified in the empirical setting. They and their diverging materialities were intimately linked to how information work was conducted at the excavation. The presence of two infrastructures designed for the same purposes of documenting the site and excavation process caused problems with scheduling and managing the work, but did at the same time make their associated premises and infrastructural obligations visible for the participants of the excavation. The older of these two infrastructures played a potentially important role as an "infrastructural stalwart," an infrastructure that stabilised another infrastructure. Conclusion: The presence of parallel, overlapping information infrastructures makes them visible and potentially less effective but also unveils their underpinnings for learning and insights in their role in information work.

Wood has been extensively used as a material for different applications over the years, therefore the understanding of different degradation processes in various environments is of great importance. In this study, the infrared spectroscopy, X-ray diffraction and chemometric methods were used to evaluate and compare the structure of archaeological and artificially degraded oak wood. The results clearly show that modifications in the structure of archaeological wood are related to the position of the material in the log (sapwood and heartwood), thus the extent of wood degradation. To identify the possible factors influencing these effects, the control wood samples were exposed to artificial white rot biodegradation with Coriolus (Trametes) versicolor and to alkali treatment (with NaOH solution). Due to the structural similarities between biodegraded wood and control or archaeological samples, this type of decay is likely to occur during natural ageing along with degradation produced by other environmental factors. Further, no real similarity was identified between the alkali treated wood and archaeological samples, indicating that such degradation does not affect wood under natural conditions.

Bayes Theorem, Fossils, Humans, Radiometric Dating, Spain, Archaeology, and Human Migration

Westernmost Europe constitutes a key location in determining the timing of the replacement of Neanderthals by anatomically modern humans (AMHs). In this study, the replacement of late Mousterian industries by Aurignacian ones at the site of Bajondillo Cave (Málaga, southern Spain) is reported. On the basis of Bayesian analyses, a total of 26 radiocarbon dates, including 17 new ones, show that replacement at Bajondillo took place in the millennia centring on ~45-43 calibrated thousand years before the present (cal ka BP)-well before the onset of Heinrich event 4 (~40.2-38.3 cal ka BP). These dates indicate that the arrival of AMHs at the southernmost tip of Iberia was essentially synchronous with that recorded in other regions of Europe, and significantly increases the areal expansion reached by early AMHs at that time. In agreement with human dispersal scenarios on other continents, such rapid expansion points to coastal corridors as favoured routes for early AMH. The new radiocarbon dates align Iberian chronologies with AMH dispersal patterns in Eurasia.

Biodiversity, Brazil, Ethnobotany, Forests, Regression Analysis, Soil, Species Specificity, Archaeology, and Plants

Multidisciplinary studies including archeology and ethnobotany that seek to understand human interventions on the landscape have obtained important results concerning Amazon biodiversity. This study aims to identify the useful plants in different phytophysiognomies related to archeological sites in the Serra de Carajás, in the state of Pará, as well as expand knowledge of the local flora. Information was collected in 76 parcels located in the influence areas of 15 archaeological sites: 45 in forest vegetation, 30 in canga vegetation and 1 in palm swamps. The species were categorized as either medicinal, food, game attractants, firewood, toxic, ritualistic and material. An assessment of the plants use potential by family was done using regression analysis for the taxa inventoried. All the phytophysiognomies studied in the vicinity of archaeological sites were expressive regarding useful species. The most representative categories were medicinal, material, game attractant, firewood and food. The floristic features related to the use of plant species by family were also expressive for Fabaceae, Myrtaceae and Chrysobalanaceae. The phytophysiognomies identified near archaeological sites feature several plant resources in different use categories, highlighting the value of local ecosystems and their potential for human use.

The Developmental Origins of Health and Disease paradigm evaluates the consequences of early life stress on health at later stages of life. Interacting with this paradigm represents a profound opportunity to leverage the lifespan and contextual approaches to human skeletal remains adopted by bioarchaeological research. Teeth and bone provide evidence for stressors experienced early in life. These events represent evidence for adaptive plasticity as Individuals survive the events through reallocation of energy to essential physiological functions, which inhibits enamel and skeletal growth. Age-at-death, adult body size, chronic infection, or childhood mortality may be used as covariates to better understand the physiological constraints operating on individual bodies following survival of early life stress. Contextual evidence from cemeteries provides clues to the ecological and cultural contingencies that exacerbate or mitigate the expression of these trade-offs. Future studies should incorporate newly derived methods that provide reproducible and precise ways to evaluate early life stress, while incorporating populations that are often neglected.
