Description
The ability of Neandertals to cope with the oscillating climate of the late Pleistocene and the extent to which these climate changes affected local Neandertal habitats remain unanswered anthropological topics of considerable scientific interest. Understanding the impact of climatic instability on Neandertals is critical for reconstructing the behaviors of our closest fossil relatives and possibly identifying factors that contributed to their extinction. My work aimed to test the hypotheses that 1) cold climates stressed Neandertal populations, and 2) that global climate changes affected local Neandertal habitats. An analysis of Neandertal butchering on Cervus elaphus, Rangifer tarandus, and Capreolus capreolus skeletal material deposited during global warm and cold phases from two French sites - Pech de l'Azé IV and Roc de Marsal - was conducted to assess the impact of climate change on butchering strategies and resource extraction. Results from a statistical analysis of surface modification on all marrow yielding long bones, including the 1st phalanx, demonstrated that specimens excavated from the cold levels at each cave have more cut marks (Wald χ2= 51.33, p= <0.001) and percussion marks (Wald χ2= 4.92, p= 0.02) than specimens from the warm levels after controlling for fragment size. These results support the hypothesis that Neandertals were nutritionally stressed during glacial cycles. The hypothesis that global climates affected local habitats was tested through radiogenic strontium isotopic reconstruction of large herbivore mobility patterns (e.g., Bison, Equus, Cervus and Rangifer), because it is known that in the northern hemisphere, mammals migrate less in warm, well-vegetated environments, but more in cold, open environments. Identifying isotopic variation in mammalian fossils enables mobility patterns to be inferred, providing an indication of whether environments at Pech de l'Azé IV and Roc de Marsal tracked global climates. Results from this study indicate that Neandertal prey species within the Dordogne Valley of France did not undertake long distance round-trip migrations in glacial or interglacial cycles, maintaining the possibility that local habitats did not change in differing climatic cycles. However, because Neandertals were nutritionally stressed the most likely conclusion is that glacial cycles decreased herbivore populations, thus stressing Neandertals.

Description
In recent years, southern Africa has figured prominently in the modern human origins debate due to increasing evidence for precocious behaviors considered to be unique to our species. These significant findings have included bone tools, shell beads, engraved ostrich eggshell, and heavily ground and engraved ochre fragments. The presence of ochre in Middle Stone Age (MSA, ~250-40kya) archaeological sites in southern Africa is often proposed as indirect evidence for the emergence of symbolic or artistic behavior, a uniquely modern human trait. However, there is no remaining artwork from this period and there is significant debate about what the ochre may have been used for. With a few exceptions, ochre has gone largely unstudied. This project tested competing models for ochre use within the Pinnacle Point (PP), South Africa research area. Combined results from characterization and sourcing analyses, color classification, heat treatment analysis, and hafting experiments suggest MSA ochre is tied to early symbolic or ritual behavior.

Description
War exacts a great social cost, not only upon its direct participants, but also upon the lives of the friends, family, and community of those who experience it. This cost is particularly evident in the increased frequencies of aggressive behaviors, including homicide, assault, and domestic violence, enacted by Western military veterans with posttraumatic stress disorder (PTSD). Similarly, among contemporary non-Westernized peoples, a cross-cultural conducted by Ember and Ember (1994) found a relationship between war and various forms of intragroup violence, including domestic violence, assaults, homicides, and violent sports. It is unknown, however, if this positive association between warfare and intragroup violence extends longitudinally for prehistoric populations uninfluenced by modern states.
To test Ember and Ember’s (1994) results in an archaeological culture, this study examines whether or not an association between war and intragroup violence was present during the Mississippian Period (ca. AD 1000-1450) of the Central Illinois Valley (CIV). The Mississippian Period of the CIV represents an ideal context for examining war and violence questions, as considerable evidence of war and violence has been amassed from archaeological and bioarchaeological analyses. High rates of skeletal trauma, fortification construction, and the placement of habitations sites in defendable areas indicate war was of particular concern during this period. Yet, little is known regarding the diachronic and synchronic variation in violence in this region.
In this research, skeletal remains representing 776 individuals from five CIV sites (Dickson Mounds, Larson, Berry, Crable, and Emmons) were analyzed for violence-related skeletal trauma, biodistance, and mortuary data. From the aggregation of these data, two models of intergroup violence and two models of intragroup violence were explored. The intergroup models examined were: 1) warfare victims from the local community and 2) warfare captives. The intragroup models assessed include: 1) domestic violence and 2) male-male fights. Results support the hypothesis that as intergroup violence increased during the Mississippian Period in the CIV, intragroup violence increased concomitantly. While warfare and intragroup violence occurred in low frequencies early in the Mississippian Period, after AD 1200, both intragroup and intergroup violence were likely endemic.

Description
Two of the defining behaviors associated with the hominin lineage are an increased reliance on tool use and the routine incorporation of animal tissue in the diet. These adaptations have been linked to numerous downstream consequences including key physiological adaptations as well as social and cognitive effects associated with modern humans. Thus, a critical issue in human evolution is how to determine when hominins began incorporating significant amounts of meat into their diets. Bone surface modifications (BSM) have long been recognized as a powerful inferential tool in identifying the differential involvement of actors responsible for altering assemblages of bone recovered from both archaeological and paleontological contexts and remain a primary source of direct evidence for butchery activities. Thus, determining the spatiotemporal context of increased carnivory in the hominin lineage relies on the accurate identification of fossil BSM.
Multidecade-long debates over the agents responsible for individual BSM indicate systemic flaws in historical approaches to identification. These debates are in part due to the extreme morphological overlap between BSM produced by certain agents of modification. The primary goal of this dissertation project therefore, is to construct probability models of BSM capable of identifying individual marks with an associated probability of assignment. Using a multivariate Bayesian approach to analyze experimentally-generated BSM data, this dissertation uses two different models, one incorporating both two and three-dimensional (3D) metric and attribute data associated with individual BSM and a second model comparing 3D geometric morphometric (GM) shape data associated with BSM.
The 2D/3D attribute model of BSM is used evaluate an assemblage of fossil BSM recovered from the Ledi-Geraru research area, Ethiopia (2.82 Ma) in spatiotemporal association with early Homo. The results of the analysis reveal compelling evidence for early butchery activities, suggesting hominins may have been using both modified and unmodified stone implements to process carcasses.
The second model, based upon 3D GM data, was used to evaluate the earliest purported evidence for stone-mediated butchery at Dikika, Ethiopia (3.39 Ma). The Dikika marks have been argued to be the result of crocodile feeding, trampling, and butchery by three different research groups. The 3D GM model evaluates the likelihood of each of these actors in the production of the controversial Dikika marks.

Description
This dissertation research describes the hunting behavior of early modern humans through the analysis of vertebrate faunal remains from Contrebandiers Cave, Morocco. Contrebandiers Cave is located in the town of Témara and is roughly 250 meters from the current shoreline of the Atlantic Ocean. The cave was excavated in the 1950s and 1970s by l’Abbé Roche, and again starting in 2007 by Dibble and El Hajraoui with total station plotting of finds. Contrebandiers Cave contains Middle Stone Age (MSA) deposits dated to Marine Isotope Stages (MIS) 5e, 5d and 5c, ~120,000 to ~96,000 years ago. The Later Stone Age (LSA) deposits are dated to MIS 2, ~20,000 years ago. The entirety of the ~12,000 vertebrate faunal remains from Dibble and El Hajraoui’s excavation were analyzed for taxonomic and taphonomic identification.
A total of 67 vertebrate taxa were identified and include ungulates, carnivores, lagomorphs, birds, tortoises, snakes and fish. The faunal remains from Contrebandiers Cave preserve surface modification that indicates both humans and carnivores acted as agents of prey accumulation. Skeletal element representation and surface modification of ungulate remains suggest that humans had primary access to small, medium and large-bodied prey. In the MSA levels, carnivore skeletal remains preserve surface modification that is interpreted as being indicative of behavior associated with skinning for fur removal.
The vertebrate faunal remains from MIS 5e and 5d indicate that humans were hunting grazers and mixed feeders from open habitats and suids from mixed habitats. The faunal remains from MIS 5c indicate that humans focused less on suids and more on mixed feeders from open habitats. The vertebrate faunal remains from MIS 2 reveal humans hunting grazers from dry, open habitats. This research provides a description of human hunting behavior in North Africa, and contributes to our understanding of early modern human behavior prior to dispersal out of Africa.

Description
Paleodietary analysis through the interpretation of stable isotopic analyses can be used to determine the approximate diet consumed at archaeological sites. The following question was investigated through the course of this research: What are the differences between the Middle Horizon capital of Tiwanaku and the associated colony of Chen Chen; and what do these differences, including those associated with paleodiet, suggest about interactions between the two sites? The main hypothesis suggested a similar dietary analysis between the two sites with two possible explanations. First, it is possible that similarities between the sites were due to the exchange and consumption of goods at both locations, perhaps through trade. Secondly, it is possible that the similarities were due to the acquisition of similar goods through local sourcing or limited trade. To assess this, an analysis was conducted based on δ13Cdiet (VPDB) values in the comparison of the city center Tiwanaku and the agricultural site of Chen Chen. Archaeological bone samples were processed from a diverse group of individuals at Chen Chen and combined with published values by Tomczak (2001), then compared against δ13C from Tiwanaku, published by Berryman (2010). After conversion to δ13Cdiet (VPDB) as described by Kellner and Schoeninger (2007), it was determined that there was no statistically significant difference between the δ13Cdiet (VPDB) values from either site, suggesting a similar ratio of goods consumed. These values were then compared to baseline values from the region to determine an approximate ratio of C3 to C4 flora or dependent fauna consumed. These data most likely support the second explanation of the main hypothesis, that both sites had access to similar goods through local sourcing or limited trade as an explanation for their similarity. However, because a similar ratio of foods consumed was determined in this analysis, it is still possible that trade occurred in both directions between Tiwanaku and Chen Chen. Additional isotopic analyses would be required to support the first claim, which can be addressed in future research projects.

Description
Objectives: The objective of this research is to develop a better understanding of the ways in which Transition Analysis estimates differ from traditional estimates in terms of age-at-death point estimation and inter-observer error. Materials and methods: In order to achieve the objectives of the research, 71 adult individuals from an archaeological site in northern Sudan were subjected to Transition Analysis age estimation by the author, a beginner-level osteologist. These estimates were compared to previously produced traditional multifactorial age estimates for these individuals, as well as a small sample of Transition Analysis estimates produced by an intermediate-level investigator. Results: Transition Analysis estimates do not have a high correlation with traditional estimates of age at death, especially when those estimates fall within middle or old adult age ranges. The misalignment of beginner- and intermediate-level Transition Analysis age estimations calls into question intra-method as well as inter-method replicability of age estimations. Discussion: Although the poor overall correlation of Transition Analysis estimates and traditional estimates in this study might be blamed on the relatively low experience level of the analyst, the results cast doubt on the replicability of Transition Analysis estimations, echoing the Bethard's (2005) results on a known-age sample. The results also question the validity of refined age estimates produced for individuals previously estimated to be in the 50+ age range by traditional methods and suggest that Transition Analysis tends to produce younger estimates than its traditional counterparts. Key words: age estimation, Transition Analysis, human osteology, observer error

Description
This study explores how early modern humans used stone tool technology to adapt to changing climates and coastlines in the Middle Stone Age of South Africa. The MSA is associated with the earliest fossil evidence for modern humans and complex cultural behaviors during a time period of dramatic climate change. Human culture allows for the creation, use, and transmission of technological knowledge that can evolve with changing environmental conditions. Understanding the interactions between technology and the environment is essential to illuminating the role of culture during the origin of our species. This study is focused on understanding ancient tool use from the study of lithic edge damage patterns at archaeological assemblages in southern Africa by using image-based quantitative methods for analyzing stone tools. An extensive experimental program using replicated stone tools provides the comparative linkages between the archaeological artifacts and the tasks for which they were used. MSA foragers structured their tool use and discard behaviors on the landscape in several ways – by using and discarding hunting tools more frequently in the field rather than in caves/rockshelters, but similarly in coastal and interior contexts. This study provides evidence that during a significant microlithic technological shift seen in southern Africa at ~75,000 years ago, new technologies were developed alongside rather than replacing existing technologies. These results are compared with aspects of the European archaeological record at this time to identify features of early human technological behavior that may be unique to the evolutionary history of our species.

Description
The Middle Stone Age archaeological record from the south coast of South Africa contains significant evidence for early modern human behavior. The south coast is within the modern Greater Cape Floristic Region (GCFR), which in the present-day encompasses the entirety of South Africa’s Winter Rainfall Zone (WRZ) and contains unique vegetation elements that have been hypothesized to be of high utility to hunter-gatherer populations. Extant paleoenvironmental proxy records for the Pleistocene in the region often indicate evidence for more open environments during the past than occur in the area in the present-day, while climate models suggest glacial presence of the WRZ that would support maintenance of C3-predominant GCFR vegetation.
These paleoenvironmental proxies sample past environments at geographic scales that are often regional. The GCFR flora is hyper-diverse, and glacial climate change-driven impacts on local vegetation could have been highly variable over relatively small geographic scales. Proxy records that are circumscribed in their geographic scale are thus key to our understanding of ancient environments at particular MSA archaeological localities.
Micromammal fossil teeth are now recognized as an abundant potential reservoir of paleoenvironmental proxy data at an extremely local scale. This study analyzed modern micromammal teeth obtained from raptor pellets at three locations on the south coast. Stable carbon isotope analysis indicates that the modern micromammals from the taxa sampled consume a wide range of δ13Cplant on the landscape when it is available, and thus stable carbon isotope analysis of micromammal teeth should act as a proxy for the range of available δ13Cdiet in a circumscribed area of vegetation.
Micromammal stable carbon isotope data obtained from specimens from one of the few well-dated MIS6-MIS5 sequences in the region (Pinnacle Point sites 13B, 30, and 9C). δ13Cenamel values for the taxa sampled indicate diets that are primarily C3, and there is almost no evidence for a dietary C4 grass component in any of the sampled specimens. This indicates that, at a minimum, pockets of C3 vegetation associated with the GCFR were likely available to hunter-gatherers at Pinnacle Point throughout the Middle and Late Pleistocene.

Description
This archaeological study analyses households at the Postclassic site of Calixtlahuaca (State of Mexico, Mexico), to evaluate the directness and collectiveness of local and imperial Aztec rule based on their effects on the commoner population. Scholars are divided as to whether Aztec rule was generally positive (due to opportunities for economic and cultural interaction) or negative (due to taxation and loss of autonomy). Contexts at Calixtlahuaca date to three periods, the Dongu (AD 1130-1370), Ninupi (1370-1450), and Yata (1450-1530) phases. The first two phases show the pre-Aztec trajectory, which is compared to the final period under Aztec rule to disentangle general trends toward regional integration from Aztec effects. Each phase includes six excavated households.
I assess economic changes on three dimensions: foreign trade, local craft production, and household wealth. Trade is evaluated for obsidian and ceramics (INAA, petrography, type classification) and local crafting is evaluated for ceramic, lithic, textile, and molded ceramic items. Wealth is measured using all excavated artifacts, with the relative values of artifact classes based on Colonial Nahuatl wills. Prior to Aztec rule, trade was increasing and diversifying, but craft production was low. Under Aztec rule, trade reoriented toward the Basin of Mexico, craft production remained low, and household wealth stabilized. Pre-Aztec inter-household variation for all dimensions is low, before increasing during the Yata phase.
Cultural changes are evaluated for ritual activities and foodways. I evaluate the degree of interhousehold variability, the overall similarity to other parts of Central Mexico, the degree of change under Aztec rule, and immigration versus emulation as potential explanations for that change. Evaluation is based on the distinction between high and low visibility objects and practices. The Dongu and Ninupi phase households at Calixtlahuaca were culturally homogeneous and regionally distinctive. During the Yata phase, the site became moderately more Aztec, but this change was unevenly distributed among households.
Together, the economic and cultural patterns at Calixtlahuaca indicate that the pre-Aztec local organization of power was relatively collective, but that this was partially overlaid by relatively indirect and non-collective Aztec imperial rule, with mildly negative effects.
