Polydactyly in the prehistoric American Southwest

General surveys of skeletal collections from Arizona for evidence of trauma and pathology led to the identification of polydactyly in two subadults. Polydactyly is a congenital condition characterised by the presence of extra digits on the hands or feet. Both affected subadults exhibit a sixth digit in the form of a branching fifth metatarsal. One of the affected individuals is an infant from the Tapia del Cerrito site exhibiting Y‐shaped fifth metatarsals indicative of postaxial type A polydactyly. The second individual is a juvenile from the Nuvakwewtaqa (Chavez Pass Ruin) site exhibiting a left fifth metatarsal with a lateral branch, also diagnosed as postaxial type A polydactyly. These two cases appear to be the first examples of polydactyly from archaeological contexts identified among subadults, and bring the total number of known cases from the American Southwest to six. Discovery of so many examples of this relatively rare condition amongst the Puebloan people of the Southwest adds to the evidence that, rather than simply being an artistic motif, rock art depictions featuring hands and feet with six digits were probably inspired by observation of the condition amongst living people. Furthermore, burial treatment of the Tapia del Cerrito infant suggests that polydactyly may have conferred a special status on the bearer. Copyright © 2006 John Wiley & Sons, Ltd.     

Understanding Abandonments in the North American Southwest

The North American Southwest is renowned for its rich archaeological record. Thousands of prehistoric houses and ceremonial centers remain partially standing or form mounds that mark prehistoric villages that were once actively occupied and remain important to the descendants. The visibility of archaeological remains has sparked interest in questions of abandonment among archaeologists and the lay public. We explore reasons for this interest, how it is manifest in archaeological research, and how perception of that research influences popular views of the past and of native people. Our focus is on explanations for the causes of site and regional abandonment as well as on explications of the processes by which abandonments occur. Essential to our perspective is the view that abandonment is a process that involves decisions to move, which may be promoted by dire circumstances, but which are most often settlement strategies. The process of moving requires economic, social, and political decisions about the places from which people move and to which they move.     

Craft economies in the north American Southwest

Debates concerning sociopolitical organization in the North American Southwest are clarified and confounded by the conclusion that craft specialization was not always a sufficient condition of complexity in the region. Understanding the relationship between varying dimensions of craft specialization (e.g., context, scale, and intensity) and sociopolitical organization in the region requires us to examine a variety of social institutions (e.g., leadership, gender, and ethnicity) that potentially generated differentiated economies. New research on middle-range societies in the North American Southwest and elsewhere in the world should focus on identifying and interpreting the archaeological signatures of specific social institutions and their linkages to craft economies.     

Early agriculture and sedentism in the American Southwest: Evidence and interpretations

Recent archaeological research in the American Southwest is rapidly altering long-held perspectives on early agricultural adaptations. The adoption of maize and squash is now reliably dated to ca. 1200 B.C., rather than 4000–2000 B.C. as previously thought, and new sites have been found in a variety of unexpected ecological settings. These emerging spatiotemporal patterns suggest that the development of sedentary communities after A.D. 500 may have been the result of changing systems of foraging, instead of simply a greater dependence on agricultural production.
