Lower Palaeolithic

The Didwana region has preserved lower palaeolithic artefacts in primary and semi-primary contexts. On the basis of geological stratigraphy of aeolian and playa sediments, artefacts occurring in a stratified context have been dated to the Middle Pleistocene. In order to work out technological evolutionary trends of the acheulian culture in this region, 301 handaxes from 10 localities have been studied following Roe's methodology, with some additional attributes. Some differences in size, shape and refinement are apparent between the collections. Statistics, diagrams, factor and cluster analyses suggest a technological evolution within the assemblages and therefore indicate the chronology of the sites. Compared with those of other known Indian sites, these handaxes may correspond to cultural stages ranging between early acheulian and very late acheulian or even early middle palaeolithic.

Lower Palaeolithic

The acheulian site at Boxgrove contains one of the most extensive areas of in situ fauna and flintwork yet discovered in Britain. This material is found in a complex sequence of sediments which represent depositional conditions from a 42 m sea level rise to the onset of a full periglacial climate. Excavation of the archaeological horizon has been accompanied by a programme of multidisciplinary research examining site formation processes, palaeolandscape and palaeoecological development, using sedimentological and environmental reconstruction techniques. Dating of the site is tentative as no absolute dates are available at present. However, comparative analysis with other British sites would suggest a position for the Boxgrove sequence within the Middle Pleistocene. The archaeological horizon is interpreted as being deposited towards the latter part of an interglacial or an interstadial period.

Eksino, on the island of Gökçeada (Imbros) in the Northeast Aegean, is a new open-air site with evidence of Palaeolithic cultural remains. Stone tools collected by an initial survey have clarified an assessment of the site from the Lower Palaeolithic, and brought to light new evidence from the Middle Palaeolithic as well as transition to the Upper Palaeolithic. Eksino is probably one of the most significant Lower Palaeolithic tool collections in the North Aegean, and finds such as chopper or chopping tools and Acheulean bifacial handaxes from the site show that the North Aegean may be another possible dispersal route from hominids to Europe via the East and Northeast Mediterranean during the Lower Palaeolithic. Middle Palaeolithic finds are frequent in the site and finds resemble the typical Mousterian type which is characterized by discoidal cores, Levallois cores and flakes, scrapers, denticulates, notches and points. Upper Palaeolithic finds are rare in the site, and a bifacial leaf point and large crescent-shaped backed pieces made on blades may reveal the presence of the Middle-Upper Palaeolithic transition on the island. This new data from Palaeolithic Gökçeada is likely to fill key geographic gaps associated with the initial dispersal of hominins through the northeast Aegean islands.

<p>Worldwide, defense technologies are rapidly evolving and are currently aiming at integrating diverse functionalities like Radar, Electronic Warfare, Communications, etc., on a singular miniaturized platform. Hence, it cannot be denied that the advancements in modern Active Phased Array Radar technologies assume a critical role towards the achievement of this goal. A typical Active Phased Array Radar comprises of an Active Antenna Array Unit (AAAU) consisting of a large number of radiating elements, Transmit/Receive (T/R) Modules with other associated RF and digital circuitry and power electronics.  This paper presents mainly the developments in Transmit/Receive (T/R) Module technology, which assimilates various stages of the technological evolution - past, current and futuristic. It discusses how these technologies contribute towards the improvement of efficiency, miniaturization and reliability without compromising its performance parameters.</p>

AbstractPart of the gravelly deposits of a combined Rhine-Meuse river of Middle Pleistocene age in the central Netherlands contains early Middle Palaeolithic artefacts. Although not in their original position, a significant part of these artefacts is hardly abraded, indicating limited fluvial transport. The artefacts have mainly been made from fluvial flint gravel boulders, originating from the Meuse catchment. Thus far, inferences for the age of the artefacts are based on the stratigraphic context and floral and faunal remains, which suggest a MIS 7 age. In this paper, OSL dating carried-out in the framework of a research aimed at the paleogeographical reconstruction of the Rhine-Meuse fluvial system in the central Netherlands and a review of published data are used to provide absolute age constraints for the artefact-bearing deposits. It is argued that the deposits were formed during the glacial phase directly preceding the Drenthe substage of the late Saalian (early MIS 6), and that at least a part of the artefacts has approximately the same age.

Cooking is unique to our species and a human universal, but until recently little has been known about its nutritional significance. This chapter reviews evidence that cooking predictably increases the net energy gained from food. The control of fire would therefore have supported rising energy budgets and novel adaptations, including reductions in digestive structures. Dietary composition would have been affected in two opposing ways. The control of fire would have allowed increased access to various food items, including honey and toxin-rich foods. However, because cooking increases dietary quality, a complementary effect would have been to narrow dietary breadth for a given population. Most archaeological evidence suggests that cooking became obligatory by the late Lower or Middle Palaeolithic (or African Stone Age), whereas biological evidence suggests that humans have relied on cooked food since the early Lower Palaeolithic.

Insight Into

The first records of extinct Caulinia goretskyi (Dorofeev) Dorofeev (synonym Najas goretskyi Dorofeev) in western Europe and of Potamogeton occidentalis M.H. Field sp. nov. were obtained from plant macrofossil analyses of Middle Pleistocene temperate stage deposits exposed at Trez Rouz, Brittany, France. Palynological assemblages recovered suggest correlation with the Holsteinian Stage. This discovery greatly expands the western limit of the paleogeographical distribution of Caulinia goretskyi. The record of Potamogeton occidentalis indicates an affinity with the eastern Asiatic flora, as the fruits resemble those of the extant Potamogeton maackianus A. Bennett. Other extinct Pleistocene species related to P. maackianus have been described, and it is possible to follow the development of this group through the Pleistocene in the European fossil record. These new finds illustrate the importance of a complete paleobotanical approach (both plant macrofossil and palynological analyses). The plant macrofossil assemblages not only provide detailed insight into local vegetation and environment, because they are often not transported long distances (in temperate areas) and can frequently be identified to species level; they can also offer the opportunity to investigate Pleistocene evolutionary trends.
