The Archaeology of Foraging and Farming at Niah Cave, Sarawak

This paper reports on the principal archaeological results of a renewed program of fieldwork in the Niah Caves (Sarawak) by an interdisciplinary team of archaeologists and environmental scientists. The paper focuses on two main themes: (1) the evidence for the changing nature of the human use of the cave and the implications of this evidence for wider debates in Southeast Asia regarding the foraging behaviors of the modern human populations who colonized the region in the later Pleistocene, and (2) the character of the later transition from foraging to farming. The first foragers visiting the caves ca. 45,000 years ago encountered much more varied landscapes than the present-day equatorial evergreen rainforest around Niah, though they were ones in which rainforest probably remained a component. A remarkable array of organic evidence indicates that the Pleistocene foragers using the caves exploited such landscapes with a combination of hunting, fishing, mollusk collection, and plant gathering, the latter including tuberous forest plants such as aroids, taro, yam, and sago palm. In the mid Holocene, when the landscape surrounding the cave was more similar to that of today, the primary use of the caves was for burials: the West Mouth of the Great Cave in particular was the location for an elaborate Neolithic cemetery that was characterized by a considerable degree of formal planning through its ca. 2500-year life. However, Neolithic people may also have used the West Mouth for habitation, as they certainly used other entrances of the cave complex. Based on present evidence, their subsistence base appears to have been forest foraging, though they were in contact with rice farmers. The remarkable antiquity and longevity of rainforest foraging knowledge and technologies at Niah appear to be among the most important conclusions emerging from the project, findings that may provide further support for arguments against the foragerfarmer dichotomy that underpins the currently dominant model of agricultural origins in Southeast Asia.

Gold(I)-catalysed one-pot synthesis of chromans using allylic alcohols and phenols

A gold(I)-catalysed reaction of allylic alcohols and phenols produces chromans regioselectively via a one-pot Friedel–Crafts allylation/intramolecular hydroalkoxylation sequence. The reaction is mild, practical and tolerant of a wide variety of substituents on the phenol

A 'long-fuse domestication' of the horse? Tooth shape suggests explosive change in modern breeds compared with extinct populations and living Przewalski's horses

Archaeological and molecular data suggest that horses were domesticated comparatively recently, the genetic evidence indicating that this was from several maternal haplotypes but only a single paternal one. However, although central to our understanding of how humans and environmental conditions shaped animals during domestication, the phenotypic changes associated with this idiosyncratic domestication process remain unclear. Using geometric morphometrics on a sample of horse teeth including Pleistocene wild horses, modern Icelandic and Thoroughbred domestic horses, Przewalski’s wild horses of recent age and domestic horses of different ages through the Holocene, we show that, despite variations in size likely related to allometry (changes to bone size in proportion to body size), natural and artificial selective pressures and geographic and temporal heterogeneity, the shape of horse teeth has changed surprisingly little over thousands of years across Eurasia: the shapes of the premolars of prehistoric and historic domestic horses largely resemble those of Pleistocene and recent wild horses. However, this changed dramatically after the end of the Iron Age with an explosive increase in the pace and scale of variation in the past two millennia, ultimately resulting in a twofold jump in the magnitude of shape divergence in modern breeds. Our findings indicate that the pace of change during domestication may vary even within the same structure with shape, but not size, suggesting a ‘long-fuse’ model of phenotypic modification, where an initial lengthy period of invariance is followed by an explosive increase in the phenotypic change. These observations support a testable model that is applicable to other traits and species and add a new layer of complexity to the study of interactions between humans and the organisms they domesticated.

The Origin of Inequality. Origini 3, edited by Andrea Cardarelli, Alberto Cazzella and Marcella Frangipane

The article reviews The Origins of Inequality, a collection of essays brought together by Andrea Cardarelli, Alberto Cazzella and Marcella Frangipane following a series of seminars on this theme at the University of Roma La Sapienza. The volume was formally presented at the university in May 2017 as the focus of a discussion of its theme by a philosopher (Giacomo Marramao), economic historian (Monika Poettinger), cultural anthropologist (Alessandro Lupo) and archaeologist (Graeme Barker). The review is an edited version of Graeme Barker’s contribution, which he structured in terms of the book‘s evidence of how the research agenda has developed in the 20 years since Gary Feinman summarised it in his final chapter in the book he edited with Douglas Price, The Foundations of Social Inequality (New York: Plenum Press, 1995)

Gold(I)-Catalysed Direct Thioetherifications Using Allylic Alcohols: an Experimental and Computational Study

A gold(I)-catalysed direct thioetherification reaction between allylic alcohols and thiols is presented. The reaction is generally highly regioselective (S(N)2′). This dehydrative allylation procedure is very mild and atom economical, producing only water as the by-product and avoiding any unnecessary waste/steps associated with installing a leaving or activating group on the substrate. Computational studies are presented to gain insight into the mechanism of the reaction. Calculations indicate that the regioselectivity is under equilibrium control and is ultimately dictated by the thermodynamic stability of the products
