Bodies in Motion: A Bioarchaeological Analysis of Migration and Identity in Bronze Age Cyprus

The analysis of human remains from the Bronze Age on Cyprus offers insights into underlying issues of social change and identity formation. Data collected from human remains from six sites throughout the southern half of Cyprus dating to the PreBA through the ProBA (2400--1100 BC) provide insight into social cohesion and group identity during this time of constant social change. Human remains were used to provide demographic data (such as number of individuals interred together, age at death and sex), health profiles (such as incidence of childhood stress, pathologies, and trauma), and robusiticty. Specifically, these data were gathered to provide an additional line of evidence regarding social identity on Cyprus during the Bronze Age and to address the issues of identity formation and change through time. Biocultural bioarchaeology is poised to address such issues through the combined examination of skeletal data in conjunction with archaeological data (such as tomb type, location, settlement pattern, subsistence pattern). In using a biocultural model, bioarchaeological data can help to examine social interaction and cultural buffering mechanisms. An additional goal of this research was the examination of bioarchaeological data to provide an additional line of evidence for issues of migration versus colonization and integration of external peoples at two pivotal times in the Bronze Age (the PreBA 1 and the ProBA 1 periods). These two time periods have been seen as moments in time where population influx occurred, usually explained by colonization or migration. This work supports the migration and hybridization model by showing a consistent lack of indicators expected to be present during times of social upheaval

Revealing importance of particles’ surface functionalization on the properties of magnetic alginate hydrogels

Iron/silica core-shell microparticles (IMPs) were functionalized by different functional groups including amine, glycidoxy, phenyl, and thiocyanate. Many of the IMPs modifications are reported for the first time. The resulting surface chemistry turned out to affect the properties of magnetic alginate hydrogels fabricated from sodium alginate and dispersed IMPs. Differences in magnetorheological properties of the obtained magnetic hydrogels can be at least partially attributed to the interactions between alginate and surface functionalities of IMPs. Density Functional Theory (DFT) calculations were carried out to get detailed insight into those interactions in order to link them with the observed macroscopic properties of the obtained hydrogels. For example, amine groups on the IMPs surface resulted in well-formed hydrogels while the presence of thiocyanate or phenyl groups – in poorly formed ones. This observation can be used for tuning the properties of various carbohydrate-based hydrogels.Polish National Agency for Academic Exchange (NAWA) for supporting the research and his stay at the University of Granada in the frame of the Bekker programme fellowship no.

Stable population structure in Europe since the Iron Age, despite high mobility

Ancient DNA research in the past decade has revealed that European population structure changed dramatically in the prehistoric period (14,000–3000 years before present, YBP), reflecting the widespread introduction of Neolithic farmer and Bronze Age Steppe ancestries. However, little is known about how population structure changed from the historical period onward (3000 YBP - present). To address this, we collected whole genomes from 204 individuals from Europe and the Mediterranean, many of which are the first historical period genomes from their region (e.g. Armenia and France). We found that most regions show remarkable inter-individual heterogeneity. At least 7% of historical individuals carry ancestry uncommon in the region where they were sampled, some indicating cross-Mediterranean contacts. Despite this high level of mobility, overall population structure across western Eurasia is relatively stable through the historical period up to the present, mirroring geography. We show that, under standard population genetics models with local panmixia, the observed level of dispersal would lead to a collapse of population structure. Persistent population structure thus suggests a lower effective migration rate than indicated by the observed dispersal. We hypothesize that this phenomenon can be explained by extensive transient dispersal arising from drastically improved transportation networks and the Roman Empire’s mobilization of people for trade, labor, and military. This work highlights the utility of ancient DNA in elucidating finer scale human population dynamics in recent history

The genetic history of the Southern Arc: a bridge between West Asia and Europe

By sequencing 727 ancient individuals from the Southern Arc (Anatolia and its neighbors in Southeastern Europe and West Asia) over 10,000 years, we contextualize its Chalcolithic period and Bronze Age (about 5000 to 1000 BCE), when extensive gene flow entangled it with the Eurasian steppe. Two streams of migration transmitted Caucasus and Anatolian/Levantine ancestry northward, and the Yamnaya pastoralists, formed on the steppe, then spread southward into the Balkans and across the Caucasus into Armenia, where they left numerous patrilineal descendants. Anatolia was transformed by intra–West Asian gene flow, with negligible impact of the later Yamnaya migrations. This contrasts with all other regions where Indo-European languages were spoken, suggesting that the homeland of the Indo-Anatolian language family was in West Asia, with only secondary dispersals of non-Anatolian Indo-Europeans from the steppe

Personal Taphonomy at Sacred Ridge: Burial 196

The fragmentary remains of a female aged 45 to 50 years were recovered from floor fill in the ventilator shaft of a Pueblo I pit house at Sacred Ridge (5LP245). Taphonomic evidence indicates facial destruction, scalping, decapitation, dismemberment, and perhaps hand or foot removal. Human hemoglobin and myoglobin residue on associated artifacts suggest that processing took place in this structure. This study addresses the significance of this feature in regard to the remains of 33 other processed individuals in another pit structure at Sacred Ridge, and the implications of these features for interpretations of Pueblo I pit structure burials

A FileMaker Pro database for use in the recording of Commingled and/or Fragmentary Human Remains

Commingled and fragmentary remains are found in numerous contexts worldwide. These assemblages typically require large scale, long term study to fully extract and contextualize meaningful data. However, when uncovered in CRM and foreign settings where remains cannot leave their country of origin, there is a need for quick, reliable data collection. Presented here is a recording system for use in field- and research-based laboratory settings. Utilizing visual forms and a minimal set of observations for skeletal elements from the cranium to the foot, the database facilitates data collection of fragment identification, age at death and sex estimation, dental observations, trauma recording, and taphonomic observations. A data dictionary is also provided, with definitions and value lists used in the database itself. The database has been used in field labs throughout the old world and by numerous researchers who have modified it to meet their own research needs. By presenting a minimal standard of data in a highly adaptable database, the recording system described here provides consistent baseline data in a user-friendly, quick-access format
