The bovids from Elandsfontein,South Africa,and their implications for the age,palaeoenvironment, and origins of the site

The bovid fossils from Elandsfontein, south-western Cape Province, South Africa, comprise 7257 individually numbered specimens from 18 species. Taxonomic comparisons with Olduvai Gorge and other African sites and the high percentage of extinct forms imply that the bones accumulated in the earlier part of the Middle Quaternary, probably sometime between 700,000 and 400,000 years ago. By extension, this is also the most likely age for the skull cap of archaicHomo sapiens (Saldanha Man) and for the occasional late Acheulean stone artifacts that accompany the animal bones. In keeping with geomorphological observations and other aspects of the fauna, the bovids indicate a relatively grassy and moist environment, apparently during an interglaciation that differed significantly from the Holocene. Geomorphological context, the frequent occurrence of partial skeletons, bone damage, and skeletal part representation suggest that carnivore feeding on carcasses scattered across a Mid-Quaternary land surface was probably the main factor shaping the Elandsfontein bone assemblage. Porcupines may also have played a role, but there is little evidence for human activity. The Elandsfontein assemblage thus provides a useful control for comparison with bone accumulations where context, associations, and bone damage indicate that people were heavily involved. For example, there are very few young animals in the otherwise attritional profile of giant buffalo from Elandsfontein, probably because carnivores often rapidly and completely consumed young carcasses. This suggests that few young carcasses would be available for human scavenging and thus that archaeological attritional profiles in which young individuals are common probably reflect active human hunting, at least of young animals.

Résumé Les fossiles de bovidés d'Elandsfontein, sud-ouest de la Province du Cap, Afrique du Sud, comportent 7257 spécimens numérotés appartenant à 18 espèces. Les comparaisons taxonomiques avec Olduvai Gorge et d'autres sites africains, ainsi que le haut pourcentage de formes éteintes, indiquent que les os ont dû s'accumuler durant la partie la plus ancienne du Quaternaire moyen, probablement entre 700,000 et 400,000 ans. Par extension, il semble que ce soit aussi l'âge le plus probable de la calotte cranienne d'une forme archaïque d'Homo sapiens (l'homme de Saldanha) ainsi que des quelques outils de l'Acheuléen récent qui accompagnaient les ossements d'animaux. En accord avec les observations géomorphologiques et d'autres aspects de la faune, les bovidés indiquent un environnement relativement humide et herbeux, évidemment durant un interglaciaire qui differe de façon significative de l'Holocène. Le contexte géomorphologique, la présence fréquente de squelettes incomplets, les os endommagés et les parties du squelette représentées suggèrent que des carnivores se nourrissaient des carcasses dispersées sur un terrain du Quaternaire moyen sont le principal facteur de la formation de l'assemblage osseux d'Elandsfontein. Les porc-épics ont peut-être aussi joué un rôle, mais il y a peu de signes de l'activité humaine. L'assemblage d'Elandsfontein est donc un témoin utile pour des comparaisons avec d'autres accumulations de faune, dans lesquelles le contexte, les associations et l'état des os indiquent que les hommes y ont joué un rôle important. Par exemple, très peu d'animaux jeunes sont représentés dans le profil par ailleurs attritionel du buffle géant d'Elandsfontein, probablement parce que les carnivores dévoraient souvent rapidement et entièrement les carcasses jeunes. Ceci indique que très peu de carcasses jeunes étaient disponibles pour les charognards humains et que les profils archéologiques attritionels dans lesquels les animaux jeunes sont fréquents reflètent probablement une chasse humaine active, tout au moins d'animaux jeunes.

     

From commodity to money: The rise of silver coinage around the Ancient Mediterranean (sixth–first centuries bce)

The reasons why the Western Mediterranean, especially Carthage and Rome, resisted monetization relative to the Eastern Mediterranean are still unclear. We address this question by combining lead (Pb) and silver (Ag) isotope abundances in silver coinage from the Aegean, Magna Graecia, Carthage and Roman Republic. The clear relationships observed between ¹⁰⁹Ag/¹⁰⁷Ag and ²⁰⁸Pb/²⁰⁶Pb reflect the mixing of silver ores or silver objects with Pb metal used for cupellation. The combined analysis of Ag and Pb isotopes reveals important information about the technology of smelting. The Greek world extracted Ag and Pb from associated ores, whereas, on the Iberian Peninsula, Carthaginians and Republican‐era Romans applied Phoenician cupellation techniques and added exotic Pb to Pb‐poor Ag ores. Massive Ag recupellation is observed in Rome during the Second Punic War. After defeating the Carthaginians and the Macedonians in the late second century bce , the Romans brought together the efficient, millennium‐old techniques of silver extraction of the Phoenicians, who considered this metal a simple commodity, with the monetization of the economy introduced by the Greeks.     

Anatomy,behavior, and modern human origins

The fossil record suggests that modern human morphology evolved in Africa between 150,000 and 50,000 years ago, when the sole inhabitants of Eurasia were the Neanderthals and other equally nonmodern people. However, the earliest modern or near-modern Africans were behaviorally (archaeologically) indistinguishable from their nonmodern, Eurasian contemporaries, and it was only around 50,000-40,000 years ago that a major behavioral difference developed. Archaeological indications of this difference include the oldest indisputable ornaments (or art broadly understood); the oldest evidence for routine use of bone, ivory, and shell to produce formal (standardized) artifacts; greatly accelerated variation in stone artifact assemblages through time and space; and hunting-gathering innovations that promoted significantly larger populations. As a complex, the novel traits imply fully modern cognitive and communicative abilities, or more succinctly, the fully modern capacity for Culture. The competitive advantage of this capacity is obvious, and preliminary dates suggest that it appeared in Africa about 50,000 years ago and then successively in western Asia, eastern Europe, and western Europe, in keeping with an African origin. Arguably, the development of modern behavior depended on a neural change broadly like those that accompanied yet earlier archaeologically detectable behavioral advances. This explanation is problematic, however, because the putative change was in brain organization, not size, and fossil skulls provide little or no secure evidence for brain structure. Other potential objections to a neural advance in Africa 50,000-40,000 years ago or to the wider Out-of-Africa hypothesis, include archaeological evidence (1) that some Neanderthals were actually capable of fully modern behavior and (2) that some Africans were behaviorally modern more than 90,000 years ago.     

Chemical characterization of ancient pottery from sudan by x‐ray fluorescence spectrometry (xrf), electron microprobe analyses (empa) and inductively coupled plasma mass spectrometry (ICP–MS)*

Sixty‐four sherds and seven natural clays from prehistoric sites in northwestern Sudan have been submitted to petrological and chemical analysis using XRF spectrometry, EMPA and ICP–MS. According to their texture, the sherds form five different groups. The high contents of P₂O₅ (more than 0.5 wt%) discerned in 19 samples and the variation of the P₂O₅ content in two samples of the same vessel can be explained by post‐depositional processes or by the ancient organic contents (e.g., milk) of the vessel. Chemical classification of the pottery bulk suggests that vessels were made locally, as only sherds from the same area show homogeneity of data.     

Building local nodes in a global sector: Clustering within the aeronautics industry in Montreal

This article analyzes the mechanisms through which metropolitan governance is established in Montreal's aeronautics sector, one of the most important and innovative industries in the region. The article also examines the role of lead firms, socio‐economic actors, and public agencies from a territorial point of view. It is established that on the one hand the existence of a small number of prime producers at the local level facilitates productive linkages among businesses through subcontracting, and on the other hand, the intensive participation of intermediate socio‐economic agencies and organizations ensures a metropolitan anchoring of the sector and creates a strong territorial identity among the players.     

The man within the breast,the supreme impartial spectator,and other impartial spectators in Adam Smith’s The Theory of Moral Sentiments

Adam Smith infused the expression ‘impartial spectator’ with a plexus of related meanings, one of which is a super-being, which bears parallels to monotheistic ideas of God. As for any genuine, identified, human spectator, he can be deemed impartial only presumptively. Such presumptive impartiality as regards the incident does not of itself carry extensive implications about his intelligence, nor about his being aligned with benevolence towards any larger whole. We may posit, however, a being who is impartial and who holds higher levels of intelligence and of benevolence, and then converse over what her sentiments would be about the matter under discussion. It is natural to conceive of a being who is unsurpassable in such qualities, who is morally supreme, and who naturally takes the definite article the without having been definitized by the writer (because unnecessary, just as we speak of ‘the world’). Signal passages, new to edition 6, suggest that Smith formulates the man within the breast as a representative of the always present and everywhere morally supreme impartial spectator. When Smith speaks of the man within the breast as ‘the supposed impartial spectator’ (all new to edition 6), we interpret ‘supposed’ as sup-pos-ed (purported), not sup-pos’d (posited).
