Design and performance of microlith implemented projectiles during the Middle and the Late Epipaleolithic of the Levant: experimental and archaeological evidence

The study comprises an experimentally based investigation of interaction between temporal change in the morphology of microlithic tools and transformations in projectile technology during the Late Pleistocene in the Levant. Archery experiments with differently designed arrows fitted with various types of microliths representing subsequent Epipaleolithic cultures of the Levant allowed analyzing performance abilities of the arrows, identifying projectile damage types characteristic of particular hafting modes, detecting factors influencing the frequency of projectile damage and estimating the frequency of projectile damage expected to be found in archaeological samples. The data obtained through the experiments applied in the analysis of the archaeological microliths from Geometric Kebaran and Natufian sites in Israel indicate different approaches to the design of projectiles fitted with microliths characteristic for these cultures. The shift in design, associated with such important economic and social transformations as transition to sedentary settlements and a broad-spectrum economy, may reflect a demand for light, flexible and efficient projectile weapons requiring low time and labor investment for preparation and retooling. The use of such efficient weapons in conditions of growing population density and restricted areas available for Natufian hunter–gatherers can be considered as one of the factors that could have affected the subsequent transition to food production that took place in the early Holocene.     

. . . in die festivitatis: gift‐giving,power and the calendar in the Carolingian kingdoms*

The reckoning of time and the composing of calendars became an important part of cultural practice in the early Middle Ages. This paper asks how important were works on the reckoning of time for those who used the calendar in everyday life. It considers whether monks and scholars may have influenced royal officials in the reckoning of time. The social symbolism of calendric knowledge is also examined in the context of gift‐giving and exchange that permeated Frankish society. Representations and uses of time reckoning are actually seen to be similar in the royal court and local contexts, but were rather different from what some scholars have imagined.     

Mitochondrial DNA diversity in a Transbaikalian Xiongnu population

Xiongnu was a confederation of nomadic pastoral tribes (~200 bc–100 ad) that founded the first nomadic empire in Central Asia. According to archeological and historical data, the tribes played a key role in ethnic and cultural processes in Central Asia and adjacent regions of Eurasia. Genetic studies of the Xiongnu published to date have focused on remains from burial grounds in present-day Mongolia, in the southern part of the ancient Xiongnu area. However, paleoanthropological materials from numerous Xiongnu cemeteries and settlements in Transbaikalia (the southern region of Eastern Siberia, Russia) in the northern part of the Xiongnu Empire have not been examined genetically. Here, we analyzed mitochondrial DNA variation in a Transbaikalian Xiongnu population based on ancient DNA obtained from skeletal remains (n = 18) at four burial grounds to complement available Xiongnu genetic diversity data. We detected 16 mitochondrial DNA haplotypes belonging to seven East Eurasian haplogroups (A, B5, C, D4, G2a, N9a, and Y) in the Transbaikalian Xiongnu series. We observed substantial similarity between Transbaikalian and Mongolian Xiongnu series with respect to main haplogroup composition and frequencies. We observed several mitochondrial DNA clusters (N9a, Y, B5, and A16) and 11 of 16 haplotypes that were previously undetected in the Xiongnu gene pool. We also observed high similarity between the Xiongnu and contemporary indigenous populations of eastern Central Asia, particularly Mongolian-speaking groups. These findings extend our knowledge of Xiongnu genetic diversity.     

Palaeoecological research in the Department of Geography and Environment,University of Aberdeen

ABSTRACT

Palaeoecological research in the Department of Geography and Environment at the University of Aberdeen can be traced back to pollen-analytical (palynological) and geomorphological collaborations in the early 1970s. The research has generally been nested within Quaternary science and it features strong interdisciplinary links with archaeology, chronostratigraphy, climate change and ecology more generally. The pollen-based emphasis has been augmented by multi-proxy approaches including plant macro- and microfossils, geochemistry and pedology. There has always been techniques- and methodologically-orientated output and the chronological focus has spanned especially the period from the Lateglacial through to the present. With an emphasis upon research since the year 2000, the account is structured around such themes as environmental change in Scotland and the rest of the British Isles, human-environment interactions in the North Atlantic region, Patagonia and Tierra del Fuego, atmospheric pollution and metals in prehistory, and carbon sequestration and chronologies. A final section looks briefly and selectively at future research.
