Grandmothers are known to increase the health and well-being of their grandchildren in many different populations. However, grandmothers may vary in their contributions based on their relatedness to their grandchildren. In some populations, maternal grandmothers decrease the risk of mortality and increase the health of their grandchildren more than paternal grandmothers. Grandmaternal influence also sometimes varies based on the gender of the grandchild. The behavioral mechanisms of grandmaternal investment are not well understood and have not been explored in the heavily intergenerational context of Eastern Europe. This study examines the behavioral variation of sixty-two Ukrainian grandmothers through interviews and a semi-structured questionnaire. I test whether maternal and paternal grandmothers differ in face-to-face contact with their grandchildren and whether the gender of the grandchild influences the frequency of face-to-face contact. Additionally, I examine qualitative responses from grandmothers on various aspects of childcare to determine whether maternal and paternal grandmothers have different childcare strategies and experience grandmotherhood in different ways. I found that maternal grandmothers have significantly more face-to-face time with their grandchildren (173.8 days out of the year as compared to 87.5 for paternal grandmothers, p

Houses and lineages are both named, corporate units of social organization defined in part on the connection between people and place. They are distinguished from one another by the relative emphasis on biological descent in societies organized on the basis of corporate group membership. Over the past 15 years, researchers have debated whether ancient Maya social organization was characterized by house or lineage organization. Drawing on ethnographic, epigraphic, and archaeological data, researchers have concluded that the ancient Maya had some characteristics of house societies, but that biological descent was an important principle. One relevant line of evidence conspicuously absent from this debate is biological distance analysis as a means of identifying patterns of biological relatedness within sites. In this chapter we review intracemetery analyses from Mesoamerica, focusing on the Maya area, and discuss what, if any, insight such analyses of biological spatial organization might bring to bear on the house versus lineage debate. We suggest that the use of biological distance analysis will not resolve debates about the relevant importance of house and biological lineage in ancient Maya society, but increasing incorporation of intracemetery analyses within existing research programs will help identify those the circumstances in which biological kinship was emphasized in Maya society. As such, intracemetery biodistance adds an important and independent line of evidence that is currently underutilized in studies of ancient Maya social organization.

Dental anthropology played a seminal role in early studies of the peopling of the New World, and was a foundation of the early three wave model proposed by Greenberg, Turner and Zegura. In recent years, however, developments in anthropological genetics, craniometry, and archaeological discoveries have largely omit-ted dental anthropology from debates regarding Native American origins. Here we consider this situation and reassert dental anthropology's relevance to the topic by presenting an inter-individual analysis of Paleoindian and Paleoamerican dentitions. A small set of dental morphological variables was used to estimate Gower similarity coefficients between individual specimens. The resulting similarity matrix was ordinated using multidimensional scaling; all analyses were per-formed in Clustan v. 7.05. While results should be considered preliminary, patterns of variation suggest morphological similarity along both coasts of North and South America with a somewhat distinct grouping of North American Paleoindians deriving from more inland portions of the continent. This pattern is consistent with recent genetic scenarios, notably the bicoastal model presented by O'Rourke and Raff (2010), which indicates that Paleoindians may have taken multiple migration routes from Beringia, moving along both coasts as well as through the ice free corridor. Future studies may build on this work to reintegrate dental data and analysis into research concerning the peopling of the New World.

Presented in the session “Boundary Bodies: Critically Thinking the Body in Contemporary Osteoarchaeology.” The last 10 years have seen an increase in high-profile historical forensic cases in the popular press, an area of investigation called forensic biohistory. This area typically involves effort to positively identify the famous dead (such as the case Richard III), of to characterize matters of facts surrounding famous historical remains (Mozart’s cause of death) or historical events (such as the Donner party and the Mountain Meadows Massacre in the Western United States), forensic biohistory remains undertheorized and under-considered as a locus of investigation in its own right. Such consideration is worthwhile however because forensic biohistory offers a unique opportunity for anthropologists to engage the public. Bodies of the famous dead serve as boundary objects through which various interested parties (including scientists) intersect. This potential is, however, coupled with a unique set of ethical challenges that researches must face because frequently we are asked to serve as arbiters and judges of the validity of narratives surrounding the bodies in question. In the presentation we discuss forensic biohistory as a district area of research and highlight some of the potential opportunities and challenges that define it as a whole.

Describing prehistoric human subsistence strategies and mobility patterns using archaeofaunal assemblages requires archaeologists to differentiate the effects of human behavior from natural taphonomic processes. Previous studies demonstrate that differences in bone density both within and between taxa contribute to variation in element representation in archaeofaunal assemblages. Measurements of contemporary Pacific Cod (Gadus macrocephalus) and Pacific Halibut (Hippoglossus stenolepis) skeletal elements using Dual Energy Absorptiometry (DEXA) and hydrostatic weighing revealed differences in bone volume density between elements and taxa. Density values were highest in Pacific cod and halibut jaw elements; the lowest bone volume densities were measured in Pacific cod and halibut basipterygia. While halibut and salmon often exhibited similar bone density values, the densities of Pacific cod elements were consistently higher than those from either salmon or halibut. These density data indicate that the remains of Pacific cod are more likely to persist in archaeological deposits. When combined with existing salmon bone density measurements, these data allow for the identification of density-mediated destruction in fish faunal assemblages from along the North Pacific rim. Analysis of cod, halibut and salmon faunal assemblages from the North Point, Cape Addington Rockshelter, Rice Ridge, Uyak and Amaknak Bridge sites revealed that density-mediated element attrition has not consistently affected cod, halibut and salmon element representation in these sites. Significant correlations identified in aggregate site assemblages were not present at finer scales of analysis; the effects of density-mediated element attrition varied between depositional contexts. This research demonstrates that bone density data can be used to differentiate the effects of density-mediated element attrition from the results of human decision-making. Once density-mediated element attrition is ruled out, archaeologists can examine the effects of human processing, transportation, preparation and disposal activities on the distribution of Pacific cod and halibut skeletal elements both within and between archaeological contexts.

In the past, efforts to prove or disprove stasis in hominids have relied upon univariate tests such as Students's t-test. Severe methodological and interpretive problems arise from the misapplication of univariate statistics to questions concerning variation in shape through time. These are questions best addressed using the multivariate approach of morphometrics. Eighteen cranial dimensions drawn from 33 mid and late Pleistocene Homo sapiens were examined using principal component analysis (PCA). PCA divided the sample into two distinct morphologies. Archaic Homo sapiens of the mid Pleistocene clustered with Wurm I neanderthals and apart from post Gottweig early anatomically modern Homo sapiens. ANOVA and Cluster analysis confirm the groups represent two different morphologies rather than a single spectrum of morphological change. These results support stasis rather than phyletic gradualism during this period of hominid evolution.

This paper focuses on how identity and racial ideology are factored into displays in the exhibit, Fossil Fragments: The Riddle of Human Origins, at the Yale Peabody Museum of Natural History. I used visitor questionnaires, observations, exhibition construction and curatorial interviews to examine that the concept of race is so ingrained in our society racial ideology and identity is automatically embedded in exhibits about human evolution. How may the exhibition inform the visitors’ perception of race and human evolution? A key aspect investigated was if the curatorial staff was conscious or unconscious about the racial ideological information present in the exhibit. By examining the exhibition construction and visitor observations, I was able to see aspects of the exhibit reinforced visitor racial ideological beliefs. In seeing how exhibition construction coupled with the legitimacy and power of the museum effect people’s thoughts on human evolution, helped me understand that not only information in the museum but information left out can be as detrimental. All the information allowed me to form recommendations change the exhibit so that identity and racial ideological information would no longer be present.

This project employs a modified version of the Bioarchaeology of Care (BoC) in an analysis of Burial 1 from the Mississippi State Asylum, Jackson, MS. Burial 1 is a skeletal individual recovered from the historic MSA cemetery. Notably, Burial 1 exhibits recidivistic cranial trauma in the form of cranial depression fractures (CDFs) and significant entheseal changes in the upper extremities. However, because there is no identifying information associated with Burial 1, interpretations of the caretaking they may have received, both prior to and after institutionalization, include short- and long-term outcomes from their community and the MSA. Additionally, Burial 1’s CDFs and subsequent traumatic brain injury likely increased their risk of being institutionalized and created complications for them in the MSA. Despite the limitations of this study, future research applying a modified BoC could lead to otherwise unknown information about the lived experiences of institutionalized patients in historic institutions of care.
