Consilience of genetics and archaeobotany in the entangled history of rice

Major leaps forward in understanding rice both in genetics and archaeology have taken place in the past decade or so—with the publication of full draft genomes for indica and japonica rice, on the one hand, and with the spread of systematic flotation and increased recovery of archaeological spikelet bases and other rice remains on early sites in China, India and Southeast Asia. This paper will sketch a framework that coherently integrates the evidence from these burgeoning fields. This framework implies a reticulate framework in the phylogeny of early cultivated rice, with multiple starts of cultivation (two is perhaps not enough) but with the key consolidations of adaptations that must have been spread through hybridisation and therefore long-distance cultural contacts. Archaeobotanical evidence allows us to document the gradual evolutionary process of domestication through rice spikelet bases and grain size change. Separate trends in grain size change can be identified in India and China. The earliest centre of rice domestication was in the Yangtze basin of China, but a largely separate trajectory into rice cultivation can be traced in the Ganges plains of India. Intriguingly, contact-induced hybridisation is indicated for the early development of indica in northern India, ca. 2000 BC. An updated synthesis of the interwoven patterns of the spread of various rice varieties throughout Asia and to Madagascar can be suggested in which rice reached most of its historical range of important cultivation by the Iron Age.     

French adventures in solidarity: revolutionary tourists and radical humanitarians

This article uses the adventures in solidarity of French tiers-mondistes and sans-frontiéristes to introduce these two movements and indicate their position within the intellectual paradigm shift that occurred in France during the 1970s. Focusing on the case of Médecins Sans Frontières (MSF), it draws attention to the important position of humanitarianism during and following the decline of revolutionary frameworks in French intellectual and public life. The study posits that a fuller appreciation of humanitarianism's relationship to political engagement will be necessary to better understand its contribution to internationalism and contemporary activism.     

Preliminary geochemical assessment of limestone resources and stone use at Maya sites in the Three Rivers Region,Belize

The carbonate bedrock of northwestern Belize is poorly understood from the standpoint of both geochemistry and the use of stone in prehispanic Maya sites for buildings and monuments. The friable nature of the rock in this topographically rugged area makes it especially difficult to distinguish monuments from bedrock spall, as little carving, if any, survives, and identification rests on location and positioning. The research presented here analyzed 63 limestone samples collected from two sites in the Three Rivers Region of Belize. ICP-MS and ICP-AES were used to characterize the major, minor, and trace element chemistry of the limestone bedrock of the region and determine the amount of geochemical variability. Another important objective was attempting to trace the movement of monument stone and determining whether it was imported from outside of the sites. Bedrock, quarries, and possible monuments were all sampled for these purposes. Bedrock proved to be similar across wide areas. However, at Chawak But'o'ob, along the flank of the Rio Bravo, changes downslope in Mg concentration suggest a leaching of the bedrock by meteoric waters based on differences in porosity. At Maax Na, a hilltop site, in contrast, such leaching is not as apparent. Many monuments at both sites were found to be composed of stone similar in chemistry to the local bedrock, including several of the identifiable stelae. However, our analyses also revealed that a few monuments at Maax Na were made of material with a different chemical composition, apparently from stone imported to the site. These results suggest that the Maya deliberately selected certain types of limestone for certain purposes, and may even have traded in non-local rock. Overall, the methods used in this pilot study indicate there is real potential in more intensive, regional assessments of the materials used at archaeological sites, even in areas where the local stone does not have a distinctive geochemical signature.     

Holey Goats: Multiple Cases of Supratrochlear Foramina in the Humerus of Caprines from the New Kingdom Pharaonic Town of Amara West,Northern Sudan

Supratrochlear foramina (STF) were recorded in fifteen per cent of goat and sheep/goat humeri from the New Kingdom pharaonic town of Amara West, in modern northern Sudan. To the authors’ knowledge, this trait has never before been reported in the published literature for goats or sheep, whether from archaeological or modern contexts. The aim of this work is twofold: to contribute to the growing corpus of studies addressing the incidence and aetiology of STF, and to raise awareness for their possible presence in caprines, thus encouraging their identification and recording in archaeological assemblages.
