It has been difficult to infer behaviours related to anterior tooth use in fossil hominids owing to a lack of broad‐based comparative studies of the relationships between front tooth use and craniodental features in modern humans. In this study, we seek to establish such a neontological baseline by exploring aspects of craniodental form among populations of recent humans that are inferred to have differed in habitual levels of ingestive and paramasticatory processing using the incisors. Morphometric data are compared among samples from three human populations: Aleutian Islanders (n=25); Arikara from the Mobridge Site, SD (n=19); and a late Woodland Bluff group from Jersey County, IL (n=24). Data for various biomechanically relevant dimensions were collected using standard callipers, while three‐dimensional (3D) coordinate data for 28 cranial landmarks were recorded using a video‐based image analysis system. These data indicate that several aspects of cranial form thought to influence the efficiency of force production on the incisors differ among the examined groups, including the positions and size of the primary masticatory muscles and the position of the dentition. For most dimensions, the Aleut sample exhibits the most mechanically advantageous configuration, the Illinois Bluff group the least advantageous configuration, while the Arikara are intermediate in form. This pattern corresponds to differences in the intensity of incisor loading among these groups, as inferred from both ethnographic reports and incisor microwear data. These results, therefore, suggest that cranial form in humans varies with subsistence‐related differences in masticatory force production and that quantitative studies of masticatory system configuration may provide useful information for studies of hominid palaeobiology.

This article examines an institutional approach to development in which indigenous institutions are viewed as a resource for achieving development. It concentrates on indigenous natural resource management (NRM) institutions which have been seen by some development agencies to be a means to address the needs of people and the environment in a way that is also participatory. Using material from Borana, Ethiopia, the article describes the indigenous NRM institutions and examines the outcome of one attempt to work with them. In the process, it shows that partnerships between development agencies and indigenous NRM institutions are often fragile, and tend to dissolve when they fail to meet the preconceptions of the developers. Through an examination of this approach to development, the article also examines the usefulness of recent broad approaches to institutions. 相似文献

Chickens were part of the Lapita cultural complex, transported into and through the Pacific by prehistoric colonists; as such they can be used as a proxy for tracking prehistoric migration and interaction. The Lapita site of Teouma in Vanuatu is well known for the recovery of complete dentate stamped pots and a cemetery containing the largest collection of Lapita period skeletons ever found. Chicken bones recovered from these excavations provide the first ancient DNA sequences from any commensal organism directly associated with a Lapita context. The ancient mtDNA sequences obtained from two Teouma chicken bones are compared with previously published archaeologically derived ancient DNA sequences to extend our understanding of the spread of chickens in Pacific prehistory. The results also show that the haplogroup E signature was present in very early populations of chickens transported into Remote Oceania. This study also adds to the suite of available data relating to isotopic signatures for commensal animals during the early settlement of Vanuatu and may reveal a different diet for Teouma chickens than those from other early prehistoric assemblages in the Pacific. 相似文献

The history of rape on trial in colonial India sheds new light on the colonial civilising mission and the claims made by white men about saving brown women from brown men. Through an analysis of almost a century of case law, this article concludes that the modernisation of law and the development of a new medico-legal understanding of rape introduced evidentiary standards that placed a heavy burden on Indian women seeking judicial remedy in colonial courts. The fear imported from Britain of false charges combined with colonial views about Indian culture to make native female complainants doubly dubious. The colonial jurisprudence has survived to devastating effect in postcolonial India and Pakistan in ways that are explored and explained by the author. 相似文献
