The technological change in the western mediterranean during the mis 3

La problemática del cambio techno-tipológico durante el Paleolítico Medio es una cuestión debatida y no resuelta en los estudios de los comportamientos técnicos de los neandertales. El proyecto de esta tesis de doctorado tiene como objetivo contribuir a la discusión en curso añadiendo nuevos datos de dos yacimientos claves Europeos, Abric Romaní (España) (nivel O y M), y la Cueva de Fumane (Italia) (unidad A9 y A5+A6). El trabajo está enfocado en el cambio entre la tecnología Levallois y discoide, que ocurre en las secuencias arqueológicas de los dos yacimientos durante el MIS3. El estudio se ha llevado a cabo desde una perspectiva cuantitativa, teniendo en consideración los conceptos de Human Behavioral Ecology y los aspectos de costes y beneficios relacionados con el cambio de las estrategias de talla.The problematic of the techno-typological change during the Middle Paleolithic is a debated and unresolved issue in the study of Neanderthals technical behaviors. The project of this Ph.D. thesis aims to contribute to the on-going discussion adding new data from two European key sites, Abric Romaní (Spain) (level O and M), and Fumane Cave (Italy) (unit A9 and unit A5+A6). The work is focused on the particular shift between Levallois and discoid technology that occurred in the archaeological sequences of the two sites during the MIS3. The study will be carried out with a quantitative perspective taking in considerations the concepts of the Human Behavioral Ecology and the aspects of costs and benefits related with the change of the knapping strategie

The Beginning of the Early Upper Paleolithic in Poland

Research on the timing of Homo sapiens dispersals in Central Europe is pivotal for understanding the behavioral trajectories of human adaptation to low biomass environments and cold climates. Previous studies on the Early Upper Paleolithic of Poland described a different scenario from the European panorama characterized by the local development of a laminar/lamellar technology from the foregoing Middle Paleolithic and the coexistence of different Aurignacian variants after 35 ka BP. In this paper, we examine this technical diversity by reassessing and revising the chronological and technological information of the key Aurignacian sites in Poland. Our study reveals that the distinctive techno-typological features of the different Aurignacian types are most likely the result of the mixing of artifacts from different chronologies. In our view, Poland was visited intermittently by Homo sapiens since the Early Aurignacian. The deterioration of the climatic conditions during the second half of MIS 3 converted the Polish territories into a satellite area of the Aurignacian settlement system

Microliths in the South Asian rainforest ~45-4 ka: New insights from Fa-Hien Lena Cave, Sri Lanka

Microliths–small, retouched, often-backed stone tools–are often interpreted to be the product of composite tools, including projectile weapons, and efficient hunting strategies by modern humans. In Europe and Africa these lithic toolkits are linked to hunting of medium- and large-sized game found in grassland or woodland settings, or as adaptations to risky environments during periods of climatic change. Here, we report on a recently excavated lithic assemblage from the Late Pleistocene cave site of Fa-Hien Lena in the tropical evergreen rainforest of Sri Lanka. Our analyses demonstrate that Fa-Hien Lena represents the earliest microlith assemblage in South Asia (c. 48,000–45,000 cal. years BP) in firm association with evidence for the procurement of small to medium size arboreal prey and rainforest plants. Moreover, our data highlight that the lithic technology of Fa-Hien Lena changed little over the long span of human occupation (c. 48,000–45,000 cal. years BP to c. 4,000 cal. years BP) indicating a successful, stable technological adaptation to the tropics. We argue that microlith assemblages were an important part of the environmental plasticity that enabled Homo sapiens to colonise and specialise in a diversity of ecological settings during its expansion within and beyond Africa. The proliferation of diverse microlithic technologies across Eurasia c. 48–45 ka was part of a flexible human ‘toolkit’ that assisted our species’ spread into all of the world’s environments, and the development of specialised technological and cultural approaches to novel ecological situations

Late Pleistocene to early-Holocene rainforest foraging in Sri Lanka:Multidisciplinary analysis at Kitulgala Beli-lena

Sri Lanka has produced the earliest clear evidence for Homo sapiens fossils in South Asia and research in the region has provided important insights into modern human adaptations and cultural practices during the last ca. 45,000 years. However, in-depth multidisciplinary analyses of Late Pleistocene and Holocene sequences remain limited to just two sites, Fa Hien-lena and Batadomba-lena. Here, we present our findings from the reinvestigation of a third site, Kitulgala Beli-lena. New chronometric dating from the site confirms the presence of humans as early as ca. 45,000 cal. BP. in the island's Wet Zone rainforest region. Our analyses of macrobotanical, molluscan, and vertebrate remains from the rockshelter show that this early human presence is associated with rainforest foraging. The Late Pleistocene deposits yielded evidence of wild breadfruit and kekuna nut extraction while the Holocene layers reveal a heavy reliance on semi-arboreal and arboreal small mammals as well as freshwater snails as a protein source. The lithic and osseous artefacts demonstrate that populations developed a sophisticated tool kit for the exploitation of their immediate landscapes. We place the rich Kitulgala Beli-lena dataset in its wider Sri Lankan context of Late Pleistocene foraging, as well as in wider discussions of our species’ adaptation to ‘extreme’ environments as it moved throughout Asia

Specialized rainforest hunting by Homo sapiens ~45,000 years ago

Defining the distinctive capacities of Homo sapiens relative to other hominins is a major focus for human evolutionary studies. It has been argued that the procurement of small, difficult-to-catch, agile prey is a hallmark of complex behavior unique to our species; however, most research in this regard has been limited to the last 20,000 years in Europe and the Levant. Here, we present detailed faunal assemblage and taphonomic data from Fa-Hien Lena Cave in Sri Lanka that demonstrates specialized, sophisticated hunting of semi-arboreal and arboreal monkey and squirrel populations from ca. 45,000 years ago, in a tropical rainforest environment. Facilitated by complex osseous and microlithic technologies, we argue these data highlight that the early capture of small, elusive mammals was part of the plastic behavior of Homo sapiens that allowed it to rapidly colonize a series of extreme environments that were apparently untouched by its hominin relatives

New perspectives on Neanderthal dispersal and turnover from Stajnia Cave (Poland).

The Micoquian is the broadest and longest enduring cultural facies of the Late Middle Palaeolithic that spread across the periglacial and boreal environments of Europe between Eastern France, Poland, and Northern Caucasus. Here, we present new data from the archaeological record of Stajnia Cave (Poland) and the paleogenetic analysis of a Neanderthal molar S5000, found in a Micoquian context. Our results demonstrate that the mtDNA genome of Stajnia S5000 dates to MIS 5a making the tooth the oldest Neanderthal specimen from Central-Eastern Europe. Furthermore, S5000 mtDNA has the fewest number of differences to mtDNA of Mezmaiskaya 1 Neanderthal from Northern Caucasus, and is more distant from almost contemporaneous Neanderthals of Scladina and Hohlenstein-Stadel. This observation and the technological affinity between Poland and the Northern Caucasus could be the result of increased mobility of Neanderthals that changed their subsistence strategy for coping with the new low biomass environments and the increased foraging radius of gregarious animals. The Prut and Dniester rivers were probably used as the main corridors of dispersal. The persistence of the Micoquian techno-complex in South-Eastern Europe infers that this axis of mobility was also used at the beginning of MIS 3 when a Neanderthal population turnover occurred in the Northern Caucasus

Archaeological and environmental cave records in the Gobi-Altai Mountains, Mongolia

Though hundreds of caves are known across Mongolia, few have been subject to systematic, interdisciplinary archaeological surveys and excavations to understand Late Pleistocene and Holocene environments. Previous cave excavations in Mongolia have demonstrated their potential for preservation of archaeological and biological material, including Palaeolithic assemblages and Holocene archaeology, particularly burials, with associated organic finds. In other cases, cave surveys found that stratigraphic deposits and archaeological materials are absent. The large number of caves makes the Mongolian Altai Mountain Range a potentially attractive region for human occupation in the Pleistocene and Holocene. Here we present the results of an interdisciplinary survey of caves in four carbonate areas across the Gobi-Altai Mountains. We report 24 new caves, some of which contain archaeological material recovered through survey and test excavations. Most caves presented limited sedimentation, and some were likely too small for human habitation. Six caves showed evidence of palaeontological remains, mostly from likely late Holocene and recent periods. The most notable anthropogenic findings included petroglyphs at Gazar Agui 1 & 13. Gazar Agui 1 also contained lithics and a bronze fragment. Tsakhiryn Agui 1 contained 31 wooden fragments that include an unused fire drilling tool kit and items commonly found in association with medieval burials. We observed that the caves remain in contemporary use for religious and economic purposes, such as the construction of shrines, mining and animal corralling. Water samples from the caves, and nearby rivers, lakes, and springs were analysed for their isotopic compositions (δ18O, δD, δ17O, 17Oexcess, d-excess) and the data, combined with backward trajectory modelling revealed that the Gobi-Altai region receives moisture mainly from western sources. These results form a baseline for future archaeological, paleoclimate and palaeoecological studies about regional seasonality and land use

Early Pastoral Economies and Herding Transitions in Eastern Eurasia

While classic models for the emergence of pastoral groups in Inner Asia describe mounted, horse-borne herders sweeping across the Eurasian Steppes during the Early or Middle Bronze Age (ca. 3000-1500 BCE), the actual economic basis of many early pastoral societies in the region is poorly characterized. In this paper, we use collagen mass fingerprinting and ancient DNA analysis of some of the first stratified and directly dated archaeofaunal assemblages from Mongolia's early pastoral cultures to undertake species identifications of this rare and highly fragmented material. Our results provide evidence for livestock-based, herding subsistence in Mongolia during the late 3rd and early 2nd millennia BCE. We observe no evidence for dietary exploitation of horses prior to the late Bronze Age, ca. 1200 BCE - at which point horses come to dominate ritual assemblages, play a key role in pastoral diets, and greatly influence pastoral mobility. In combination with the broader archaeofaunal record of Inner Asia, our analysis supports models for widespread changes in herding ecology linked to the innovation of horseback riding in Central Asia in the final 2nd millennium BCE. Such a framework can explain key broad-scale patterns in the movement of people, ideas, and material culture in Eurasian prehistory
