Wild Food: Plants,Fish and Small Animals on the Menu for Early Holocene Populations at al-Khiday,Central Sudan

Al-Khiday, located on the bank of the White Nile in Sudan, offers an exceptionally preserved stratigraphic sequence, providing a unique opportunity to use organic residue analysis to investigate diet and subsistence during the Khartoum Mesolithic and the Early Neolithic, a period of nearly 3500 years (7000–4500 cal BC). While the vast and diverse Mesolithic fish assemblage indicates a strong reliance on products from aquatic habitats, floodplains, vegetated marshes, and open water, results from the lipid residue analysis suggest that the fish were not cooked in ceramic pots, but consumed in other ways. Rather, pots were more specialized in processing plants, including wild grasses, leafy plants, and sedges. These results, confirmed by experimental analysis, provide, for the first time, direct chemical evidence for plant exploitation in the Khartoum Mesolithic. Non-ruminant fauna (e.g., warthog) and low lipid-yielding reptiles (e.g., Adanson’s mud turtle and Nile monitor lizard), found in significant numbers at al-Khiday, were likely also cooked in pots. There is little evidence for the processing of wild ruminants in the Mesolithic pots, suggesting either that ruminant species were not routinely hunted or that large wild fauna may have been cooked in different ways, possibly grilled over fires. These data suggest sophisticated economic strategies by sedentary people exploiting their ecological niche to the fullest. Pottery use changed considerably in the Early Neolithic, with ruminant products being more routinely processed in pots, and while the exploitation of domesticates cannot be confirmed by a small faunal assemblage, some dairying took place. The results provide valuable information on Early and Middle Holocene lifeways in central Sudan.

     

Changing regional systems of innovation in Greece: the impact of regional innovation strategy initiatives in peripheral areas of Europe

In the context of convergence and cohesion between the European regions, the promotion of innovation in regions that are in different phases of development has been a central objective of European regional policy. For this purpose, the European Commission has launched many innovation schemes and many European regions have conducted initiatives of this kind. In this article, based on the implementation of successive European regional innovation projects in three Objective 1 regions in Greece, namely Central Macedonia, Western Macedonia and Thessaly, the trajectory and the changes that have occurred in their system of innovation are examined. At the outset, considering the outcomes of the first phase of the RTP/RIS exercise, the obstacles in forming these regions' dynamic innovation systems are identified. Thereafter, upon the outcomes of the follow-up exercise of RIS+projects, an imminent change in these regions is observed, highlighting the marking of an innovation-oriented policy addressed to create a supporting institutional framework and shaping the regional innovation environment. Based on these observations, it is argued that European regional policy, via these innovation schemes, has significantly contributed to the reinforcement of innovation systems of participating regions.     

Shifting social networks along the Nile: Middle Holocene ceramic assemblages from Sai Island, Sudan

During the middle Holocene, profound changes in environment, economy, and social relations laid the foundations for the emergence of Africa’s earliest polities: the Egyptian Old Kingdom and the Kerma state. Regional shifts in economy and society may be reflected in local changes in patterning of ceramic production and exchange. Analysis of two pottery assemblages from Sai Island, north Sudan, reveals dramatic shifts in the scale of cultural spheres and the nature of cross-cultural interaction between 5000 BC (Khartoum Variant) and 2600 BC (Pre-Kerma). Near-sedentary Khartoum Variant hunter–gatherers at site 8-B-10C participated in a longstanding cultural sphere that extended far into the Sahara, but were beginning to focus more tightly on resources by the Nile. By Pre-Kerma times, Sai occupants familiar with animal husbandry started to use southwest Asian plant domesticates; they began to experiment with large-scale storage facilities and engage in long-distance trade along the Nile, outside of their own cultural boundaries. Beyond a shift in axes for contact from east–west to north–south, these changes signal progressive geographic and temporal compression of cultural entities, amidst accelerating processes of economic innovation and social change that finally culminated in the polities of Egypt and Kerma.     

An improved PCR method for endogenous DNA retrieval in contaminated Neandertal samples based on the use of blocking primers

Neandertal skeletal remains are usually contaminated with modern human DNA derived from handling and washing of the specimens during excavation. Despite the fact that the distinct Neandertal haplotypes allow the design of specific primer pairs, for instance in most of the mitochondrial DNA (mtDNA) hypervariable region 1 (HVR1), the human contaminants can often outnumber the endogenous DNA, thus preventing a successful retrieval of Neandertal sequences. We have developed a novel PCR method, based on the use of blocking primers that preferentially bind to modern human contaminant DNA and block their amplification, and greatly improve the efficiency of Neandertal DNA retrieval. We tested the method in four El Sidrón Neandertal samples (two teeth and two bone fragments) with different contamination levels and taphonomic conditions, and we have been able to significantly increase the Neandertal yield from figures around 25.23% (5–69.6%) up to 90.18% (75.3–100%).     

Ancient standards of volume: negevite Iron Age pottery (Israel) as a case study in 3D modeling

Hand-made cylindrical vessels unearthed in excavations of Iron Age IIA sites in the Negev Highlands constitute the largest and most dominant ceramic assemblage of simple-shaped vessels found in Israel. The volumes and linear dimensions of these vessels were analyzed based on computer 3D models reconstructed according to their drawn profiles. This analysis revealed the rules that could have been employed by the ancient potters in order to produce vessels of given volumes. These rules demonstrate the human ability to reveal approximate (but inherent) geometric relationships between form and volume and deploy them in everyday life.     

The First Crusade and the Latin east as seen from Venice: the account of the Translatio sancti Nicolai

The Translatio sancti Nicolai is the earliest Venetian source to describe the deeds of the first crusaders from Venice. It is most likely based on an eyewitness account of the events that was later rewritten in order to provide the historical context for the translation of St Nicholas's relics to Venice. This source ambivalently depicts the nature of the crusader battles, both emphasizing the spiritual value of this fight, mainly seen as a way to fulfil the sequela Christi , and highlighting the significant economic implications of the Christian conquest of the Holy Land.
