Burial practices at the Mesolithic-Neolithic transition in Britain: change or continuity?

There is no doubt that the Mesolithic-Neolithic transition was a time of great change. It has been suggested that at this time people began to disarticulate their dead and use caves and monuments as ways of interacting with the ancestors. This paper looks at the transition from a Mesolithic perspective in order to identify evidence for change and continuity. It is suggested that certain practices such as disarticulation and the use of caves are much earlier in date and thus provide some continuity. Practices such as the use of shell middens for the deposition of human remains and the construction of monuments stand out as innovations, but are not necessarily the result of a new ideology.Prehod iz mezolitika v neolitik nedvomno predstavlja čas, v katerem je prišlo do velikih sprememb. Predlagano je bilo, da so v tem obdobju ljudje pričeli raztelešati svoje umrle in začeli uporabljati jame in spomenike za interakcije s predniki. V članku se ukvarjamo s prehodom iz mezolitske perspektive, da bi lahko prepoznali dokaze o spremembi in kontinuiteti. Predlagamo, da so se določeni običaji, kot je raztelešenje in uporaba jam, pojavili bolj zgodaj in tako nudijo kontinuiteto. Običaji, kot je uporaba školjčnih kupov za odlaganje človeških ostankov in izdelava spomenikov, pa predstavljajo inovacije, ki niso nujno posledica nove ideologije

Meeting Report: Biomedical Research Conference

This meeting brought together staff from the Department of Life Sciences at Anglia Ruskin University and the 150 final-year BSc (Hons) Biomedical Science students taking the ‘Current Advances in Biomedical Science’ module led by Richard Jones. The module aimed to promote students’ career prospects and interest in exciting research through employability, studentship and biomedical research conference days at Anglia Ruskin University (ARU) in semester 2, 2014. The venue for all three conference days was the Mumford Theatre at ARU’s Cambridge Campus. The Mumford Theatre has excellent acoustics and normally hosts theatre companies. Knowledge accumulated during these days was assessed at the end of the module using a 1 hour written examination

Amino acid racemization dating of marine shells: a mound of possibilities

Shell middens are one of the most important and widespread indicators for human exploitation of marine resources and occupation of coastal environments. Establishing an accurate and reliable chronology for these deposits has fundamental implications for understanding the patterns of human evolution and dispersal. This paper explores the potential application of a new methodology of amino acid racemization(AAR) dating of shell middens and describes a simple protocol to test the suitability of different molluscanspecies. This protocol provides a preliminary test for the presence of an intracrystalline fraction of proteins(by bleaching experiments and subsequent heating at high temperature), checking the closed system behaviour of this fraction during diagenesis. Only species which pass both tests can be considered suitable for further studies to obtain reliable age information. This amino acid geochronological technique is also applied to midden deposits at two latitudinal extremes: Northern Scotland and the Southern Red Sea.Results obtained in this study indicate that the application of this new method of AAR dating of shells has the potential to aid the geochronological investigation of shell mounds in different areas of the world

The Resettlement of the British Landscape: Towards a chronology of Early Mesolithic lithic assemblage types

During the Upper Palaeolithic Britain was visited intermittently, perhaps only on a seasonal basis, by groups often operating at the margins of their range. The Early Mesolithic, by contrast, witnessed the start of the permanent occupation of the British landscape, with certain key sites showing evidence for long-lasting occupation from the very start of the period. However, currently our understanding of the timing and tempo of the Mesolithic colonisation and infilling of the landscape is limited because of the paucity of precise radiocarbon measurements. In this article we assess and model existing radiocarbon measurements to refine current typochronological models for the first two millennia of the Holocene. This is a necessary first step towards understanding the Mesolithic resettlement of the British Isles. Our results throw new light on the relationship between the last Upper Palaeolithic 'Long Blade' industries and early Mesolithic assemblages, as well as refining our understanding of the chronology of early Mesolithic assemblage types. Our data also suggest regional patterning to the timing of Mesolithic settlement and throw new light on issues of population movement and adoption of new technologies

Floristic diversity and its relationships with human land use varied regionally during the Holocene

Humans have caused growing levels of ecosystem and diversity changes at a global scale in recent centuries but longer-term diversity trends and how they are affected by human impacts are less well understood. Analysing data from 64,305 pollen samples from 1,763 pollen records revealed substantial community changes (turnover) and reductions in diversity (richness and evenness) in the first ~1,500 to ~4,000 years of the Holocene epoch (starting 11,700 years ago). Turnover and diversity generally increased thereafter, starting ~6,000 to ~1,000 years ago, although the timings, magnitudes and even directions of these changes varied among continents, biomes and sites. Here, modelling these diversity changes, we find that most metrics of biodiversity change are associated with human impacts (anthropogenic land-cover change estimates for the last 8,000 years), often positively but the magnitudes, timings and sometimes directions of associations differed among continents and biomes and sites also varied. Once-forested parts of the world tended to exhibit biodiversity increases while open areas tended to decline. These regionally specific relationships between humans and floristic diversity highlight that human–biodiversity relationships have generated positive diversity responses in some locations and negative responses in others, for over 8,000 years

Spatial organisation within the earliest evidence of post-built structures in Britain

This paper explores tool-using activities undertaken in and around the earliest known evidence of post-built structures in Britain. Microwear results associated with at least three structures identified at the Early Mesolithic site of Star Carr, North Yorkshire, are examined as a means of identifying activity zones associated with the diverse stone tools used to process a variety of materials (e.g. wood, bone, antler, plant, hide, meat, fish). With 341 lithic artefacts analysed, this research represents the first microwear study focused on the post-built structures at Star Carr. A combination of spatial and microwear data has provided different scales of interpretation: from individual tool use to patterns of activity across the three structures. Different types of tool use observed have aided interpretations of possible activity areas where objects were produced and materials were processed. Zones of activity within one of the structures suggest that the working of some materials was more spatially restricted than others; even where there are high densities of flint deposition, spatial patterns in tool-using activity were observed. From this, it is interpreted that social norms and behaviours influenced the spatial organisation of different spaces. Our results demonstrate the importance of combining microwear analysis with GIS to explore function and variability in the use of Mesolithic structures - providing new insights into their role as social spaces

Drink types unmask the health risks associated with alcohol intake – prospective evidence from the general population

Background & aims: Uncertainty still exists on the impact of low to moderate consumption of different drink types on population health. We therefore investigated the associations of different drink types in the form of beer/cider, champagne/white wine, red wine and spirits with various health outcomes. Methods: Over 500,000 participants were recruited to the UK Biobank cohort. Alcohol consumption was self-reported as pints beer/cider, glasses champagne/white wine, glasses of red wine, and measures of spirits per week. We followed health outcomes for a median of 7.02 years and reported all-cause mortality, cardiovascular events, ischemic heart disease, cerebrovascular events, and cancer. Results: In continuous analysis after excluding non-drinkers, beer/cider and spirits intake associated with an increased risk for all-cause mortality (beer/cider: hazard ratio, 1.56; 95% confidence interval, 1.45–1.68; spirits: 1.47;1.35–1.60), cardiovascular events (beer/cider: 1.25;1.17–1.33; spirits: 1.25;1.16–1.36), ischemic heart disease (beer/cider:1.12;0.99–1.26 [P=0.056]; spirits: 1.17;1.02–1.35), cerebrovascular disease (beer/cider: 1.63;1.32–2.02; spirits: 1.59;1.25–2.02) and cancer (beer/cider: 1.14;1.05–1.24; spirits: 1.14;1.03–1.26), while both champagne/white wine and red wine associated with a decreased risk for ischemic heart disease only (champagne/white wine: 0.84;0.72–0.98; red wine: 0.88;0.77–0.99). Conclusions: Our findings do not support the notion that alcohol from any drink type is beneficial to health. Consuming low levels of beer/cider and spirits already associated with an increased risk for all health outcomes, while wine showed opposite protective relationships only with ischemic heart disease

An integrated analysis of Maglemose bone points reframes the Early Mesolithic of Southern Scandinavia

The extensive peat bogs of Southern Scandinavia have yielded rich Mesolithic archaeological assemblages, with one of the most iconic artefacts being the bone point. Although great in number they remain understudied. Here we present a combined investigation of the typology, protein-based species composition, and absolute chronology of Maglemosian bone points. The majority of the bone points are made from cervids and bovines. However, changes both in species composition and barb morphology can be directly linked to a paucity of finds lasting nearly 600 years in Southern Scandinavia around 10,300 cal BP. We hypothesize that this hiatus was climate-driven and forced hunter-gatherers to abandon the lakes. Furthermore, the marked change in bone points coincides with a change in lithic technology. We, therefore, propose that the Maglemose culture in Southern Scandinavia is fundamentally divided into an Early Complex and a Late Complex
