Over the past five decades, archaeologists have proposed a wide range of methods for the study of spatial organization within hunter-gatherer sites. Many of these methods sought to identify the spatial location of activities based on patterns of behavior observed in ethnographic contexts. While this resulted in productive observations at certain sites, many of these methods were tailored to specific situations and thus could not be applied to a wide range of sites. For example, open-air sites rarely contain preserved bone or features, such as hearths, which were central components to identifying characteristics of site structure. In addition, many of these methods often did not take into consideration the temporal dynamics of the occupation, i.e., that many sites were formed through subsequent occupations of differing duration. This paper proposes the use of two related methods that assume many assemblages are the result of more than one occupation. The methods target the distribution of lithic artifacts, the most ubiquitously preserved of archaeological materials, and accounts for the potential that the final resting place of artifacts was the result of both intentional and unintentional movement by humans and a host of biological and geological processes. The main goal of this paper is to use an understanding of how these processes influenced the formation of site structure to estimate the relative number and duration of occupations for each site in the sample. These new methods will be presented and explained through the study of seven open-air Middle Paleolithic sites in France but are applicable to a wide range of hunter-gatherer sites.

Among the American population, there is a general misunderstanding of human evolution and human life in the Paleolithic. Beyond the mechanics of biological evolution, there is confusion over what sorts of modern-day behaviors are vestiges from humans’ evolutionary past. My master’s thesis explores what kind of misconceptions about Paleo-life and human evolution circulate in popular discourse and where these misconceptions stem from. Drawing on the experiences of community members in upstate New York, I conducted a multimodal discourse analysis via surveys, interviews, and a reflexive media analysis to triangulate my findings. Through these two discourses – that of the everyday understanding of human evolution and Paleo-life versus what kinds of messages popular media portrays on these same issues – I determined that popular media constitutes a large resource of information gathering for the general public. Furthermore, the media highlighted by my research participants to exhibit themes of human evolution had clear messages on race, gender, and violence that research participants largely believe to be successful modes of “survival of the fittest” and thus cultural “survivals” from when we were evolving to our modern form. Participant and media messages regarding race, gender, and violence mirror the logics behind white American Exceptionalism; though these everyday epistemologies are argued by my participants to be biological in nature, they merely reflect today’s values and are logics used to successfully participate in American society. That is to say, the repetitive, naturalizing messages portrayed by popular media on human evolution and paleo-life both construct and reify the popular understanding that modern concepts of race, gender and violence are biological and have led to the success of our species. With these findings, I offer science educators recommendations on how to best utilize edutainment to correct these outdated narratives. / Graduate

Background Obesity and associated metabolic dysregulation are linked to impaired cognitive function and alterations in brain structure, which increases the risk of age-related dementia. Increased glucocorticoid (GC) exposure may be a potential mediator of these negative effects on the brain. Methods and results In paper 1, we tested the relationship between cortisol levels, brain morphology and cognitive function in 200 women and men. Salivary cortisol levels were negatively related to cortical surface areas in prefrontal brain regions in both sexes. In participants with type 2 diabetes, high salivary cortisol levels were associated with lower memory performance. In paper 2, we tested in 70 overweight women the effects on tissue-specific GC metabolism of a Paleolithic diet or a diet following the Nordic nutrition recommendations. The 24-month interventions led to decreased expression of the GC-activating enzyme 11βHSD1 in adipose tissue, interpreted as a normalization of an obesity-related disturbance in GC metabolism. Furthermore, GC metabolism by 5α-reductase increased substantially after 2 years, an unexpected and novel result. The outcomes did not differ by diet. In paper 3, 20 women included in paper 2 were examined with functional magnetic resonance imaging (fMRI) while performing a memory task at baseline and after 6 months. Memory performance improved and functional brain responses increased in the hippocampus. Once again, the results were similar in both diet groups. In paper 4, 24 overweight participants with type 2 diabetes were examined with fMRI, using the same memory test as in paper 3, at baseline and after 12 weeks of intervention with a Paleolithic diet with or without exercise training. Functional brain response increased in the hippocampus, but memory was not improved. The addition of physical exercise did not alter the results. Conclusion Cortisol levels are linked to prefrontal brain structure and, at least in type 2 diabetes, lower memory performance. Furthermore, the dysregulated GC metabolism in obesity can be reversed by long-term diet- induced weight loss. Finally, dietary interventions with associated metabolic improvements alter functional brain responses during memory testing, including increased activation of the hippocampus. Whether these changes are linked to alterations in GC exposure and mediate improved cognition requires further study.

Kabazi II est un site de plein air, situé sur la deuxième rangée des Monts de Crimée. Après sa découverte en 1986, les investigations archéologiques effectuées entre 1987 et le milieu des années 90 ont établi que Kabazi II avait auparavant servi de lieu de chasse et d’abattage pour les groupes néanderthaliens de la région. Les études archéozoologiques antérieures (Patou-Mathis 2003, 1999, 2005, 2006a, 2006b) ont déterminé que les stratégies de subsistance des Néanderthaliens du Kabazi II étaient très spécialisées et principalement axées sur la chasse des petits groupes de Equus hydruntinus mais aussi, à l’occasion, sur la chasse d’autres espèces. Ces comportements ont persisté malgré les changements climatiques et technologiques à travers l’histoire d’occupation du site. Cette étude présente l’analyse des assemblages fauniques encore inédits des niveaux II/1,II/2-1, II/2, II/3, II/4, II/5, II/7, II/8, II/9, II/13, II/13A de Kabazi II. Nos résultats sont en accord avec ceux obtenus parles d’études antérieures ; cependant, des différences par rapport à la fonction du site ont été constatées et un lien possible avec Kabazi V, un abri sur roche tout près de Kabazi II, a été établi. On croit que la persistance des activités de subsistance des Néanderthaliens de Kabazi II pendant presque 100 000 ans de présence est due à la polyvalence des ânes asiatiques tels que Equus hydruntinus, au contexte géographique et géologique de la région ainsi qu’aux caractéristiques du site elles-mêmes. / Kabazi II is an open-air site situated within the second chain of the Crimean Mountains. Discovered in 1986, and intensively excavated from 1987 to the mid 1990’s, Kabazi II served as a kill and butchery site for Neanderthal groups in the area. Previous faunal analyses at Kabazi II (Patou-Mathis 2003, 1999, 2005, 2006a,2006b) indicate that the subsistence strategies of the Neanderthals at Kabazi II were highly specialized and were primarily focused on hunting small groups of Equus hydruntinus as well as occasional encounter-based hunting of other mammal species. This practice had apparently remained unchanged in spite of changes in lithic industry, climate, and local vegetation cover. This study presents the analysis of previously unexamined faunal assemblages from Levels II/1, II/2-1, II/2, II/3, II/4, II/5, II/7, II/8, II/9, II/13, II/13A. The results obtained here concur with those of the previous analyses however differences in the use of Kabazi II have been observed and a possible link with the nearby rock-shelter, Kabazi V has been determined. It is believed that the persistence of the hunting practices of the Neanderthals at Kabazi II throughout its nearly 100 000 year sequence of occupations is due to the versatility of wild asses such as Equus hydruntinus, the geography and geology of the study area, in addition to characteristics of Kabazi II itself.

In recent years there has been discussion of the many health benefits of the paleodiet, a diet that consist of food that we are evolutionary and genetically adapted to consume. The agricultural revolution introduced mankind to dietary changes that did not suit our biology, and is now the main reason for the nutrition-based diseases in developed countries. The purpose of this paper is to review both the archaeological methods used to explain the paleodiet and the knowledge we have about our hunter-gatherer ancestors and to see if there is any evidence to claim that the paleodiet could be an answer to food-health related diseases. This paper will also discuss the different perspectives behind the many dietary changes in human evolution and how they reflect on man’s dietary conditions today. The material used for this research is based on studies in anthropology, biology, genetics and epidemiology. The theory behind this paper is based on the positivism knowledge founded on properties and relations between measurable studies. Based on interpretations by reason and logic this paper is concluded through deductive reasoning. The results show that food-related diseases and syndromes are absent from traditional hunter-gatherer societies and that they first start to manifest if a western-based diet is adopted. According to our evolutionary and biological structure, man is not adapted to consuming dairy or agricultural products and we are, in fact, genetically identical to our Paleolithic ancestors. Therefore, because we have the same dietary conditions as the paleo hunter-gatherer, we would be considerably more healthy if we adopted a Paleolithic based diet.

Teilw. zugl: Diss. u.d.T.: Lengyel, Györgyi: Lithic technology of the Upper Palaeolithic and Epipalaeolithic of Raqefet Cave, Mount Carmel, Israel.

Abstract The thesis consists of two parts: theoretical and practical. In the theoretical part of my thesis I would like to describe the development of art, especially the prehistoric times, the specifics of the time and gradual changes, focusing on the life of prehistoric creatures and their development. Zoom personalities related to this topic, especially illustrators, painters, filmmakers, who are involved in public awareness about the picture of the time. Finally, I would like to mention the influence of authors and styles of the 20th century and approached the work of contemporary artists inspired by this theme. In the practical part of the thesis, deals with the presentation selected and died out creatures. To this I would like to take the theoretical and practical knowledge based on my work involved.

Ce travail de recherche se propose d’aborder la question des pointes au Paléolithique moyen en Europe occidentale par l’étude de ces objets en se servant de trois outils de recherche mis en confrontation : la tracéologie lithique, la technologie lithique et l’étude morphologique. Le problème de l’utilisation de ces outils comme armes de chasse est au coeur du questionnement. Nous tentons d’y répondre par la constitution d’un corpus expérimental spécifique, la mise en place d’une méthodologie adaptée et l’étude complète des pointes de 3 séries archéologiques représentatives : le site de plein air de Therdonne (Oise), celui de Beauvais (Oise) et le site de la grotte de Spy (Belgique). / This research aims to address the question of lithics points in the Middle Paleolithic in Western Europe through the study of these objects using three research tools in confrontation : traceology, lithic technology and morphological study . The question of using these tools as hunting weapons is central to the inquiry. We try to respond by the formation of a specific experimental corpus, the establishment of an appropriate methodology and full study of points of three representative archaeological series : the open-air site of Therdonne (Oise), the Beauvais one (Oise) and the site of the cave of Spy (Belgium).

Le modèle « Out of Africa » est profondément ancré dans les réflexions portant sur les peuplements paléolithiques. Pour le Pléistocène inférieur et moyen ancien, plusieurs vagues de dispersion des premiers hominidés à partir de l’Afrique de l’Est sont avancées, en particulier vers le Proche-Orient sur la base de trois sites majeurs : Dmanisi, ‘Ubeidiya et Gesher Benot Ya‘aqov. Cette théorie véhicule également l’idée d’imports répétés de techniques nouvelles, notamment le façonnage bifacial.Cependant, une déconstruction des mécanismes inhérents à ce modèle permet d’identifier des obstacles conceptuels et méthodologiques issus du « paradigme de la flèche », simplifiant et réduisant la complexité des phénomènes techniques et culturels.Afin de réintégrer à la question l’espace et le temps, dont l’absence au sein d’« Out of Africa » est rédhibitoire, nous utilisons une vision évolutive des techniques basée sur des réflexions de philosophie, d’ergonomie et de géographie. Cette vision, reprise par des paléolithiciens depuis une quinzaine d’années, a conduit à concevoir une méthodologie techno-fonctionnelle centrée sur les notions d’outil, de geste et de fonctionnement.Une étude approfondie utilisant cette approche a été menée sur quatre assemblages est-africains et proche-orientaux, complétée par des observations portant sur trois autres collections. Les informations obtenues permettent de discuter des processus d’évolution technique sur le temps long, de proposer une vision alternative des peuplements qui considère en particulier l’idée d’inventions du façonnage bifacial indépendantes, et enfin d’envisager des espaces culturels à différentes échelles de temps et d’espace. / The “Out of Africa” model is deeply rooted in the issues of Paleolithic settlement. For the Lower and Early Middle Pleistocene, several waves of early hominid dispersal from Africa have been proposed, especially to the Near East on the basis of three major sites: Dmanisi, ‘Ubeidiya and Gesher Benot Ya‘aqov. This theory also conveys the idea of repeated imports of new techniques, including bifacial shaping.However, the mechanisms inherent in this model are deconstructed: it allows to identify conceptual and methodological obstacles from the “arrow paradigm”, which simplifies and reduces the complexity of technical and cultural phenomena.The absence of space and time in the “Out of Africa” model is a crippling flaw. To reintroduce these dimensions in the debate, an evolutionary view of technics is used and is inspired by thoughts from philosophy, ergonomics and geography. In Paleolithic prehistory, this point of view, developed over past fifteen years, led to work out a techno-functional methodology focused on notions of tool, gesture and functioning.A detailed study using this approach was conducted on four assemblages from East Africa and Near East, with some supplementary observations on three other collections Then a discussion is offered on various topics: (1) the processes of technical evolution over long time, (2) an alternative vision of settlements, which particularly considers the idea of independent inventions of bifacial shaping, and finally (3) the ability to define cultural spaces on different scales of time and space.
