Grief and Burial in the American Southwest: The Role of Evolutionary Theory in the Interpretation of Mortuary Remains

Evolutionary theory, in consort with Marxism and processualism, provides new insights into the interpretation of grave-good variation. Processual interpretations of burial sites in the American Southwest cite age, sex, or social rank as the main determinants of burial-good variation. Marxist theorists suggest that mortuary ritual mediates social tension between an egalitarian mindset and an existing social inequality. Evolutionary theory provides a supplementary explanatory framework. Recent studies guided by kin-selection theory suggest that humans grieve more for individuals of high reproductive value and genetic relatedness. Ethnographic examples also show that individuals mourn more intensively and, thus, place more social emphasis on burials of individuals of highest reproductive value (young adults). Analysis of grave goods from La Ciudad, a Hohokam site in the American Southwest, supports the hypothesis that labor value, reproductive value, and grief contributed to grave-good differentiation. At La Ciudad, individuals between the ages of 10 and 20 possessed more and higher-quality grave goods on average than any other age group. Grief at the loss of a young adult of high reproductive and labor value may facilitate explanation of mortuary variation at La Ciudad, as well as other sites in the greater Southwest and beyond

The Age, Function, and Distribution of Keyhole Structures in the Upper Susquehanna River Valley

This paper provides a summary of current data regarding the age, geographical distribution, and function of keyhole structures in the upper Susquehanna River Valley of north-central Pennsylvania and south-central New York. Keyhole structures have been identified at 11 sites in the West and North Branches of the Susquehanna River Valley. The feature type likely originated in the West Branch Valley from which it spread to the north, south, and east. Their main period of use was during the latter portion of the Late Woodland period, between approximately 1230 and 1670 A.D. Given the locations of the sites along major waterways, as well as their possible associations with agricultural villages and hamlets, keyhole structures may have functioned as storage facilities for foodstuffs or, perhaps, as winter houses; however, the possibility that they served multiple functions, including the common interpretation as sweat lodges, cannot be ruled out based on current data
