Artificial selection associated with domestication is the best-known example of a major anthropogenic morphological evolution preserved in the archaeological record. However, the impact of the domestication process and dispersal on the morphological evolution of animals has been far less explored. To fill this gap, we focused on 4500 years of evolution in Western Europe Sus scrofa, covering the Neolithic transitiona major anthropogenic ecological disturbance involving landscape modification and the translocation of domestic mammals. Using geometric morphometrics on key phenotypic markers preserved in the archaeological record, associated with isotopic studies, we explored how, and in response to which cultural drivers, the Neolithic niche construction has influenced the morphological evolution of Western European wild boars (Sus scrofa scrofa). The decoupling of size and shape components from bone morphological variation has facilitated the identification of several processes of phenotypic diversification of Sus s. scrofa in response to human behaviour during the Neolithic transition in Western Europe.

We present a review of Mesolithic sites that have yielded freshwater fish remains and focus on a case study from an occupation dated to the eighth millennium BC at Les Cabônes rock shelter, located near the Doubs River, that yielded over 9,300 fish remains. Cyprinid (including bream, roach, and minnow) remains are predominant; other taxa, such as salmonids (probably trout), grayling, burbot, perch, and eel, are represented by only a few remains each. Although small fish (about 15 cm) constitute the majority of the catch, we provide evidence
that their accumulation in the shelter is mostly of human origin. These catches constituted a source of food throughout the year, particularly during the lean season. According to the ecological preferences of the fish
species identified, it is highly unlikely that they were caught in a single location. The animals were probably caught with passive fishing equipment in shallow banks or side channels where large numbers of specimens could be captured. Fishing appears to have been optimised to maximise yield-to-effort ratios, together with other wetland resources. Finally, we question the presumed causal links between site micro-setting,
site occupation, and increased dependence on aquatic resources and reduced group mobility.

In northwestern Europe, extensive studies have documented the vegetation and faunal recomposition with the replacement of the cold steppe-tundra ecosystem by the forested temperate ecosystem we can still observe. Paleoecological interest focused on the extinct large mammals species like the Mammoth. In comparison, little has been done to decipher the ecological adaptation of the surviving ...

Their impact on ecosystem dynamics was particularly pronounced in north-western Europe where hunter-gatherer societies experienced a succession of environmental transformations, including the expansion and dispersal of biotic communities and changing herbivore habitats. Recent archaeozoological studies and AMS direct dating on mammalian bones/or bone collagen allow to

Whether X-ray computed [micro-] tomography ([μ]CT) imaging of these fossils may further damage aDNA remains debated. Although the effect of X-ray on DNA in living organisms is well documented, its impact on aDNA molecules is unexplored. Here we investigate the effects of synchrotron X-ray irradiation on aDNA from Pleistocene bones. A clear correlation appears between decreasing aDNA quantities and accumulating X-ray dose-levels above 2000 Gray (Gy). We further find that strong X-ray irradiation reduces the amount of nucleotide misincorporations at the aDNA molecule ends. No representative effect can be detected for doses below 200 Gy. Dosimetry shows that conventional μCT usually does not reach the risky dose level, while classical synchrotron imaging can degrade aDNA significantly. Optimised synchrotron protocols and simple rules introduced here are sufficient to ens...

Following the cold conditions of the late Pleniglacial, these oscillations start with the warming phase of the Late-glacial interstadial (GI1e to GI-1a), which was interrupted by the Younger Dryas, and succeeded by the definitive global warming of the early Holocene heralding the current climatic conditions. The warm phases of the Late-glacial and early Holocene generally correspond to an expansion and intensification of human settlement, which is reflected by a large number of archaeological sites, rich in faunal remains. Such dramatic, rapid climatic fluctuations have triggered not only significant changes in ecosystems but could also be the origin of important cultural transitions. In fact, research on hunter-fisher-gatherer groups during the pre-Neolithic period has been flourishing in recent decades. Establishing links between cultural innovation and/or persistence with environmental variation requires deciphering local prehistoric frameworks and recording tools at different levels of resolution. For this purpose, skeletal remains (bones, teeth, antlers and horns) of animal specimens and human individuals yield insightful information on diet, environment, phylogeny, and cultural practices through studies in paleoanthropology, zooarchaeology, bone industry, proteomics, stables isotopes, and paleogenetics. Researchers working in all disciplines related to human subsistence and settlement patterns during the Late-glacial and early Holocene from various geographical contexts and settings are invited to contribute. Papers providing archaeological overviews and/or methodological and theoretical insights relevant to these issues are also welcomed. This session intends to stimulate exchanges and discussions pushing the limits of disciplinary frontiers.
