Violence in the first millennium BCE Eurasian steppe: Cranial trauma in three Turpan Basin populations from Xinjiang, China.

OBJECTIVES: Violence affected daily life in prehistoric societies, especially at conflict zones where different peoples fought over resources and for other reasons. In this study, cranial trauma was analyzed to discuss the pattern of violence experienced by three Bronze to early Iron Age populations (1,000-100 BCE) that belonged to the Subeixi culture. These populations lived in the Turpan Basin, a conflict zone in the middle of the Eurasian Steppe. METHODS: The injuries on 129 complete crania unearthed from the Subeixi cemeteries were examined for crude prevalence rate (CPR), trauma type, time of occurrence, possible weapon, and direction of the blow. Thirty-three injuries identified from poorly preserved crania were also included in the analyses except for the CPR. Data was also compared between the samples and with four other populations that had violence-related backgrounds. RESULTS: Overall, 16.3% (21/129) of the individuals showed violence-induced traumatic lesions. Results also indicated that most of the injuries were perimortem (81.6%), and that women and children were more involved in conflict than the other comparative populations. Wounds from weapons accounted for 42.1% of the identified cranial injuries. Distribution analysis suggested no dominant handedness of the attackers, and that blows came from all directions including the top (17.1%). Wounds caused by arrowheads and a special type of battle-ax popular in middle and eastern Eurasian Steppe were also recognized. DISCUSSION: A comprehensive analysis of the skeletal evidence, historical records, and archeological background would suggest that the raiding to be the most possible conflict pattern reflected by the samples. The attackers were likely to have been nomadic invaders from the steppe (such as the Xiongnu from historical records), who attacked the residents in the basin more likely for their resources rather than territory or labor force.

Miniaturization optimized weapon killing power during the social stress of late pre-contact North America (AD 600-1600).

Before Europeans arrived to Eastern North America, prehistoric, indigenous peoples experienced a number of changes that culminated in the development of sedentary, maize agricultural lifeways of varying complexity. Inherent to these lifeways were several triggers of social stress including population nucleation and increase, intergroup conflict (warfare), and increased territoriality. Here, we examine whether this period of social stress co-varied with deadlier weaponry, specifically, the design of the most commonly found prehistoric archery component in late pre-contact North America: triangular stone arrow tips (TSAT). The examination of modern metal or carbon projectiles, arrows, and arrowheads has demonstrated that smaller arrow tips penetrate deeper into a target than do larger ones. We first experimentally confirm that this relationship applies to arrow tips made from stone hafted onto shafts made from wood. We then statistically assess a large sample (n = 742) of late pre-contact TSAT and show that these specimens are extraordinarily small. Thus, by miniaturizing their arrow tips, prehistoric people in Eastern North America optimized their projectile weaponry for maximum penetration and killing power in warfare and hunting. Finally, we verify that these functional advantages were selected across environmental and cultural boundaries. Thus, while we cannot and should not rule out stochastic, production economizing, or non-adaptive cultural processes as an explanation for TSAT, overall our results are consistent with the hypothesis that broad, socially stressful demographic changes in late pre-contact Eastern North America resulted in the miniaturization-and augmented lethality-of stone tools across the region.

Mesolithic projectile variability along the southern North Sea basin (NW Europe): Hunter-gatherer responses to repeated climate change at the beginning of the Holocene.

This paper investigates how former hunter-gatherers living along the southern North Sea coast in NW Europe adapted to long-term and short-term climatic and environmental changes at the beginning of the Holocene. It is argued that contemporaneous hunter-gatherers repeatedly changed their hunting equipment in response to changing climate and environment, not just for functional reasons but mainly driven by socio-territorial considerations. Based on a Bayesian analysis of 122 critically selected radiocarbon dates a broad chronological correlation is demonstrated between rapid changes in the design and technology of stone projectiles and short but abrupt cooling events, occurring at 10.3, 9.3 and 8.2 ka cal BP. Combined with the rapid sea level rises and increased wildfires these climatic events probably impacted the lifeways of hunter-gatherers in such a way that they increasingly faced resource stress and competition, forcing them to invest in the symbolic defense of their social territories.

The Iceman's lithic toolkit: Raw material, technology, typology and use.

The Tyrolean Iceman, a 5,300-year-old glacier mummy recovered at the Tisenjoch (South Tyrol, Italy) together with his clothes and personal equipment, represents a unique opportunity for prehistoric research. The present work examines the Iceman's tools which are made from chert or are related to chert working - dagger, two arrowheads, endscraper, borer, small flake and antler retoucher - and considers also the arrowhead still embedded in the shoulder of the mummy. The interdisciplinary results achieved by study of the lithic raw material, technology, use-wear analysis, CT analysis and typology all add new information to Ötzi's individual history and his last days, and allow insights into the way of life of Alpine Copper Age communities. The chert raw material of the small assemblage originates from at least three different areas of provenance in the Southalpine region. One, or possibly two, sources derive from outcrops in the Trentino, specifically the Non Valley. Such variability suggests an extensive provisioning network, not at all limited to the Lessini mountains, which was able to reach the local communities. The Iceman's toolkit displays typological characteristics of the Northern Italian tradition, but also comprises features typical of the Swiss Horgen culture, which will come as no surprise in the toolkit of a man who lived in a territory where transalpine contacts would have been of great importance. Ötzi was not a flintknapper, but he was able to resharpen his tools with a medium to good level of skill. Wear traces reveal that he was a right-hander. Most instruments in the toolkit had reached their final stage of usability, displaying extensive usage, mostly from plant working, resharpenings and breaks. Evidently Ötzi had not had any access to chert for quite some time, which must have been problematic during his last hectic days, preventing him from repairing and integrating his weapons, in particular his arrows. Freshly modified blade tools without any wear suggest planned work which he never carried out, possibly prevented by the events which made him return to the mountains where he was killed by a Southern Alpine archer.

From Neandertals to modern humans: New data on the Uluzzian.

Having thrived in Eurasia for 350,000 years Neandertals disappeared from the record around 40,000-37,000 years ago, after modern humans entered Europe. It was a complex process of population interactions that included cultural exchanges and admixture between Neandertals and dispersing groups of modern humans. In Europe Neandertals are always associated with the Mousterian while the Aurignacian is associated with modern humans only. The onset of the Aurignacian is preceded by "transitional" industries which show some similarities with the Mousterian but also contain modern tool forms. Information on these industries is often incomplete or disputed and this is true of the Uluzzian. We present the results of taphonomic, typological and technological analyses of two Uluzzian sites, Grotta La Fabbrica (Tuscany) and the newly discovered site of Colle Rotondo (Latium). Comparisons with Castelcivita and Grotta del Cavallo show that the Uluzzian is a coherent cultural unit lasting about five millennia, replaced by the Protoaurignacian before the eruption of the Campanian Ignimbrite. The lack of skeletal remains at our two sites and the controversy surrounding the stratigraphic position of modern human teeth at Cavallo makes it difficult to reach agreement about authorship of the Uluzzian, for which alternative hypotheses have been proposed. Pending the discovery of DNA or further human remains, these hypotheses can only be evaluated by archaeological arguments, i.e. evidence of continuities and discontinuities between the Uluzzian and the preceding and succeeding culture units in Italy. However, in the context of "transitional" industries with disputed dates for the arrival of modern humans in Europe, and considering the case of the Châtelperronian, an Upper Paleolithic industry made by Neandertals, typo-technology used as an indicator of hominin authorship has limited predictive value. We corroborate previous suggestions that the Middle-to-Upper Paleolithic transition occurred as steps of rapid changes and geographically uneven rates of spread.

The bow and arrow in northern North America.

There were at least four waves of bow and arrow use in northern North America. These occurred at 12000, 4500, 2400, and after about 1300 years ago. But to understand the role of the bow and arrow in the north, one must begin in the eighteenth century, when the Russians first arrived in the Aleutian Islands. At that time, the Aleut were using both the atlatl and dart and the bow and arrow (Fig. ). This is significant for two particular and important reasons. First, there are few historic cases in which both technologies were used concurrently; second, the bow and arrow in the Aleutian Islands were used almost exclusively in warfare. The atlatl was a critical technology because the bow and arrow are useless for hunting sea mammals. One cannot launch an arrow from a kayak because it is too unstable and requires that both hands remain on a paddle. To use an atlatl, it is necessary only to stabilize the kayak with a paddle on one side and launch the atlatl dart with the opposite hand. The Aleut on the Alaska Peninsula did indeed use the bow and arrow to hunt caribou there. However, in the 1,400 km of the Aleutian Islands, there are no terrestrial mammals except humans and the bow was reserved almost exclusively for conflicts among them. The most significant event in the history of the bow and arrow is not its early introduction, but rather the Asian War Complex 1300 years ago, when the recurve and backed bows first entered the region, altering regional and hemispheric political dynamics forever.

Perimortem weapon trauma in an adult male skeleton from the Italic necropolis of Opi Val Fondillo (VI-V century BC; Central Italy).

The author describes weapon traumatic lesions in an adult male skeleton, that was excavated in the Italic necropolis of Opi Val Fondillo, Central Italy. The preservation of the skeleton is very good. The skull shows a linear lesion across the diploE of the right parietal and occipital bones; the edge of the traumatic lesion is smooth and perpendicular to the bone surface. The injury was probably inflicted with a sharp-edged weapon and the violence of the stroke caused the detachment of bone fragments and fractures that radiate from the point of impact. A sharp-edged linear traumatic lesion, probably inflicted with a blade, is visible on the ventral surface of the vertebral bodies of atlas and axis; the blade detached the right transverse process of the atlas and penetrated in the vertebral body of the axis. Another sharp-edged linear traumatic injury is observed on the anterior surface of the body of thoracic vertebrae. There are no traumatic lesions of the ribs and the last injury was probably inflected down with a blade, while the body lying on the ground. The posterior surface of the diaphysis of the right femur shows an incomplete perimortem fracture, probably due to a compression down upon. Probably the adult male was killed during a fight and enemy had done with him, while he was lying on the ground holding fast his legs strongly. A comparison is made between the lesions and the modality of combat as well as the type of the weapons used by the Samnitic warriors.
