Abstract The appearance of weaponry - technology designed to kill is a critical but poorly established threshold in human evolution. It an important behavioural marker representing evolutionary changes ecology, cognition, language and social behaviours. While the earliest weapons are often considered be hand-held consequently short-ranged, subsequent distance crucial development. Projectiles seen as improvement over contact weapons, by some have originated only with our own species Middle...

The thermal decomposition of the acetates calcium, sodium, silver and copper(II) have been investigated using thermogravimetry differential analysis, together with analysis gaseous products formed during process. results indicate that major organic product is either acetone or acetic acid, depending on whether final solid oxide metal.
ABSTRACT Increasing evidence suggests that bifacial technology (Acheulian, Mode 2) arrived in Europe during the early Middle Pleistocene, i.e. significantly earlier than previously proposed. In northern France and Britain, much of age attribution for these assemblages has been based on biostratigraphy lithostratigraphy rather absolute dates. This study presents a systematic application electron spin resonance (ESR) dating sedimentary quartz ESR/U‐series fossil tooth enamel to key Acheulian...
Activation energies for the vacuum thermal decomposition of calcium, strontium and barium carbonates have been determined from thermogravimetric data, using Coats Redfern equation. A computer program, written in 4100 Algol, was used to process data obtain order (n) reactions. In all three cases, a value ofn=2/3 closest agreement with experimental results, suggesting that occurs at progressively shrinking spherical interface. The activation obtained were close corresponding values enthalpy...
Did Neanderthal hunters drive mammoth herds over cliffs in mass kills? Excavations at La Cotte de St Brelade the 1960s and 1970s uncovered heaps of bones, interpreted as evidence intentional hunting drives. New study this Middle Palaeolithic coastal site, however, indicates a very different landscape to featureless plain that was previously envisaged. Reconsideration bone themselves further undermines ‘mass kill’ hypothesis, suggesting these were simply final accumulations undisturbed...
The Anthropocene represents the emergence of human societies as a ‘great force nature’. To understand and engage productively with this emergent global force, it is necessary to its origins, dynamics structuring processes long-term evolutionary product niche construction, based on three key characteristics: tool making, habitat construction most importantly: social network engineering. exceptional capacities behaviourally modern humans, constituting ultrasociality, are expressed through...
Abstract
Northern Europe experienced cycles of hominin habitation and absence during the Middle Pleistocene. Fluvial gravel terrace sites in east Britain north France provide a majority data contributing to this understanding, mostly through presence or stone-tool artefacts. To date, however, relatively few have been radiometrically dated, many not excavated modern times, leading an over-reliance on selectively sampled poorly dated lithic assemblages. This includes Fordwich (Kent, UK), where over 330...
In 1988 an area of 12,000 m 2 in Quarry at Boxgrove, West Sussex, was identified as being under threat front gravel and sand extraction. It decided to sample the threatened 1989 with a series 6 test pits. The results this survey two areas that merited further investigation, excavations were carried out 2/C 2/D 1990 1991 respectively. These concentrated on main Pleistocene landsurface (Unit 4c) revealed spreads knapping debris associated production flint handaxes. Two pits Q2/C produced...
ABSTRACT In 2011, a programme of field research was undertaken to effect the stabilization an unstable section in West Ravine at key Neanderthal occupation site La Cotte de St Brelade on Channel Island Jersey. As part this essential remedial work threatened analysed characterize its archaeological and palaeoenvironmental potential as well provide optically stimulated luminescence (OSL) dates. The determined, through two concordant OSL dating programmes, that formed extensive sequence...
Magnetic moment measurements and ultra-violet diffuse reflectance spectroscopy have been used to investigate the structure of chloroacetates copper(II). These studies indicate that cupric monochloroacetate dihydrate is dimeric trichloracetate tetrahydrate monomeric. Cupric dichloracetate forms an intermediate case. The thermal decomposition these compounds under nitrogen has studied using thermogravimetry differential analysis, together with analysis products decomposition. major organic...
The early Middle Pleistocene human material from Boxgrove (West Sussex, UK) consists of a partial left tibia and two lower incisors separate adult individual. These remains derive deposits assigned to the MIS 13 interglacial at about 480 ka have been referred as Homo cf. heidelbergensis. much larger skeletal sample Sima de los Huesos (Atapuerca, Spain) is dated succeeding 12, 430 ka. This fossil has previously heidelbergensis but now placed within Neanderthal clade. Because scarcity their...
Abstract Archaeological studies of early weaponry have relied for decades on ethnographic parallels—whether from ethnohistorical accounts, literature, or objects studied in museum collections. While such accounts and collected provided key data the past, including morphometrics functionality, few explored quality data. In this paper, we critically assess a dominant theoretical paradigm, namely utility collections to Pleistocene archaeological material. Our focus is how spear are used propose...
