Deciphering the mtDNA record of prehistoric population movements in Oceania

Pierson, Melanie Jane January 2007 (has links)
This thesis uses mitochondrial DNA (mtDNA) phylogenies to explore patterns of past human mobility in Oceania. To extend the current knowledge of mtDNA variation in Oceania, 20 entire mt genomes were sequenced and analysed in a data set of more than 144 sequences from Australia, Oceania, Island Southeast Asia and Taiwan. The MinMax Squeeze method enabled this large data set to be analysed with an optimality criterion (Pierson et al. 2006). The analysis revealed two major groups of haplogroups in Oceania, distinguished by the relationships to others outside of the region: an 'ancient' set of types whose phylogenies and distributions suggest they are descended from the Pleistocene-era settlers of Near Oceania, and a second 'young' group whose presence in Oceanic populations may reflect more recent movements into Near Oceania. The detailed phylogenies of these haplogroups presented here will aid in future investigations of human mtDNA in Oceania, allowing samples to be screened by defining mutations to target haplogroups of interest. A large data set of global entire human mt DNA sequences was assembled from public data bases and tested for evidence of selection and recombination. These tests, and phylogenetic analyses of random subsets of the data set, found high levels of homoplasy in the sequences. Homoplasy in the control region of the mtDNA molecule was examined in particular, resulting in a relative scale of mutability at each position of the ~1kb sequence. Subsequent phylogenetic tests of weighting schemes derived from this analysis for the control hypervariable region I (HVR-I) did not show demonstrable improvements over the unweighted examples, but did highlight instances in which the HVR-I sequence failed to predict the more robust trees generated by the coding region. Finally, the HVR-I and diagnostic SNPs were sequenced in a set of 46 Polynesian samples from Auckland, and this data was analysed within a large set of HVR-I sequences (more than 4000) from Oceanic, Asian and the American populations available from public data bases. These analyses were informed by the whole mtDNA phylogenies generated earlier in the project, and add population level data to the emerging picture of prehistoric female mobility gained from entire mtDNA analyses.

Resource intensification in pre-contact central California: a bioarchaeological perspective on diet and health patterns among hunter-gatherers from the lower Sacramento Valley and San Francisco Bay

Bartelink, Eric John 16 August 2006 (has links)
In this study, I use bioarchaeological data derived from human burials to evaluate subsistence change in mid-to-late Holocene central California (circa 4950-200 B.P.). Previous investigations in the region have proposed two competing models to account for changes in subsistence patterns. The seasonal stress hypothesis argues that the increased reliance on acorns and small seeds during the late Holocene led to improved health status, since these resources could be stored and used as a “buffer” against seasonal food shortages. In contrast, resource intensification models predict temporal declines in health during the late Holocene, as measured by a decline in dietary quality and health status, increased population crowding, and greater levels of sedentism. I test the hypothesis that health status, as measured by childhood stress and disease indicators, declined during the late Holocene in central California. I analyzed 511 human skeletons from ten archaeological sites in the Sacramento Valley and San Francisco Bay area to investigate temporal and spatial variability in diet and health. I analyzed a subset (n = 111) of this sample to evaluate prehistoric dietary patterns using carbon and nitrogen stable isotope ratios. Indicators of health status show significant temporal and regional variation. In the Valley, tibial periosteal reactions, porotic hyperostosis, and enamel hypoplasias significantly increased through time, implying a decline in health status. In the Bay, health indicators show little temporal variability. However, inter-regional comparisons indicate a higher prevalence of stress and disease indicators among Bay Area skeletons than in the Valley skeletal series. The stable isotope data from human bone collagen and apatite also indicate significant interregional differences in prehistoric diets between the Bay and the Valley. In the Bay, diets shifted from high trophic level marine foods to a more terrestrially focused diet over time. In the Valley, there are no significant dietary trends observed in the data. Dental caries and antemortem tooth loss are significantly more prevalent in the Valley than in the Bay, and closely match the isotopic findings. The paleopathological findings provide support for late Holocene resource intensification models posited for the Valley, but not for the Bay Area.

A Multi-Scalar Analysis of the Politics Of Obsidian Consumption in the West Mediterranean (ca. 6th - 2nd millennia B.C.)

Freund, Kyle 11 1900 (has links)
This dissertation details and contextualizes the changing nature of obsidian circulation and use in the West Mediterranean from the sixth to second millennia B.C., with a particular focus on the reflexive relationship between obsidian consumption and long-term socio-economic processes. Central themes in this work include, a) the significance of exchange and long-distance relations in the creation and maintenance of social distinction, b) the specific role of obsidian circulation and consumption in these processes, and c) a longue durée investigation of the history of obsidian use and maritime activity in the West Mediterranean from the Neolithic through Bronze Age. Methodologically this is achieved through, a) the compilation and interrogation of a database of regional obsidian studies over the past 50 years, and b) the generation of new primary data via the typological analysis of 6,895 obsidian artifacts from 46 archeological sites in Sicily and Sardinia, 2,103 of which were also elementally characterized using X-ray fluorescence (XRF) spectrometry to determine their geological source. Central to this work is the idea that obsidian ‘characterization’ studies represent a powerful means of engaging with major social science questions, where a particular regional dataset can be used to contribute to debates of global significance. Thus, while the focus of this work is on obsidian consumption in the West Mediterranean, its implications are far-reaching. / Dissertation / Doctor of Philosophy (PhD)

On the Study of Health in Prehistory

Denning, Kathryn 09 1900 (has links)
This thesis examines the approaches used in the study of health in prehistory, focusing in particular on the potential of archaeology to contribute to this field. Archaeological data have been under-used in studies of prehistoric health; obstacles to their utilization include the popular conception of archaeological information as less direct than osteological data, the idea that scientific research must produce testable hypotheses to be valid, and the challenge of integrating large quantities of information of different temporal scales into synthetic interpretations. Alternative conceptions of scientific research, and the use of the Braudelian model of historical time as an organizing structure,circumvent these obstacles and permit a fuller use of archaeological data in reconstructing patterns of past health. In particular, archaeological information about social behaviour as well as subsistence and factors pertinent to disease ecology, can form a basis of inferences about health in prehistoric communities. A demonstration of this approach, using recent archaeological data and interpretations for the Mississippian site of Cahokia, suggests that prevailing negative opinions of the health of Mississippian groups and early agriculturalists may not be supportable with regard to the people of Cahokia. / Thesis / Master of Arts (MA)
