We use an eco-cultural niche modelling approach to evaluate the importance of different environmental and geographical variables in determining where early humans could have lived, and the impact of habitat suitability on different aspects of the eastern African MSA lithic record. We apply random forests, a powerful and highly flexible machine-learning tool for niche modelling, in combination with palaeoclimatic simulations at high temporal resolution. Topographic factors, distance to water and net primary productivity are found to be the most important factors in predicting MSA site locations in eastern Africa, followed by a suite of precipitation and then temperature variables. We find that environmental suitability has a significant impact on overall assemblage composition, suggesting that populations occupying optimal and peripheral zones within the landscapes use distinct artefact types and reduction technologies. These include the use of burins, bifacially retouched tools and bipolar technology, which are more likely to occur in the most optimal areas.

Despite its importance, the MSA has not been evenly investigated across Africa, and West Africa in particular remains poorly understood. Although new research is beginning to fill in this crucial gap of knowledge, the existing MSA chronologies in West Africa only rely on Optically Stimulated Luminescence (OSL) dating. In this context, the increasing use of a multi-method dating approach appears essential to strengthen this emerging geochronological framework. Here, we apply such approach to constrain the age of Bargny locality, located in close proximity to the modern Senegalese coast (South of Dakar), and which documents one of the oldest MSA occupations in West Africa. Specifically, we combine OSL and Electron Spin Resonance (ESR) methods to date the MSA sites of Bargny 3 (BG3) and Bargny 1 (BG1). A mean OSL age of 127±8 ka may be proposed for the MSA of BG3, which is in good agreement with a mean Ti-H ESR age of 125±14 ka from the same unit. Interestingly, similar ages are obtained by OSL (144±7 ka) and Ti-H ESR (138±14 ka) for the MSA horizon from BG1. While these results illustrate the great potential of the combined OSL-ESR dating approach to establish robust chronologies, they also contribute to improve the geographical and chronological resolution of the MSA record in West Africa. More specifically, they also corroborate the presence of MSA occupations along the Senegambian coast around the MIS 6-MIS 5 transition. In combination with the associated estuarine environments and mangrove forest, the evidence from Bargny adds to the known diversity, and likely complex behaviour, of early human populations living by Africa’s coastlines.</div></div>","PeriodicalId":101053,"journal":{"name":"Quaternary Environments and Humans","volume":"2 6","pages":"Article 100044"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142744005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coevally, Siberia and Central Asia would also have been reached by IUP moderns and, in the process, Western Europe’s Neandertals would have been acculturated, explaining the innovations (namely, body ornamentation) seen in the Châtelperronian. However, current usage of the IUP label confuses terminology and conceals issues of association raised by syn- and post-depositional disturbance, genomic patterns do not correlate with skeletal morphology, and the people of the Bachokirian and the Ranisian had Neandertal ancestors who lived many centuries after those technocomplexes’ start dates, as did a Neandertal from Spy (Belgium), a site of the Ranisian. Moreover, the stratigraphic provenience and taxonomic affinity of the fossils associated with the Uluzzian, the Protoaurignacian, and the Ahmarian are uncertain. The former is coeval with the Châtelperronian, the latter two emerge no earlier than ∼41,500 years ago, and the sufficiently complete fossils of broadly the same age are of mosaic anatomy and mixed ancestry. For western Eurasia, our review supports the Assimilation model, whereby ten millennia of converging cultural developments and increased demic interaction bridge the initial (Neandertal) and final (Cro-Magnon) terms of a complex evolutionary and historical process. Throughout, the observed diversity cannot be reduced to a taxonomic dichotomy. As human biology varied in a continuous space and material culture varied in a discrete space, no one-to-one correspondence between the two domains can exist.

Similarly, this study underscores concerns regarding the representation of modern samples collected from diverse Vadda clans inhabiting various ecological zones and engaging in different subsistence practices, potentially skewing the conclusions of preceding research. In this study, fresh ethnoarchaeological data are used to examine some misconceptions prevailing about the <em>Warugas</em> (clans) as well as the use of the term <em>Wanniyalaetto</em> as a synonym for Vaddas.

Studies of ancient materials rely on the assumption that <em>δ</em><sup><em>3</em>4</sup>S values have been minimally altered by diagenesis, yet meaningful analyses of sulfur isotope preservation/alteration are rare. This paper has 3 objectives: (1) to review and revise previous approaches to evaluating sulfur isotope alteration of collagen, (2) to evaluate sulfur isotope preservation in Great Lakes mammoth (<em>Mammuthus</em> spp.) and mastodon (<em>Mammut americanum</em>) bone, tooth, and tusk collagen, and (3) to make inferences about proboscidean diets and habitat preferences based on <em>δ</em><sup>34</sup>S values. To evaluate sulfur isotope preservation in collagen we recommend 3 approaches. First, researchers should examine collagen %C, %N, and atomic C:N values, and exclude samples whose values fall outside the expected ranges (defined according to context-specific considerations). Second, researchers should examine collagen %S, C:S, and N:S values, and exclude samples that fall outside the ranges for modern taxa. These ranges are subject to revision, but this study provides a new compilation of modern mammalian collagen with %S = 0.14–0.63, C:S = 185–873, and N:S = 55–266 (n=119). Third, researchers should check for correlations between collagen <em>δ</em><sup>34</sup>S and %S, C:S, or N:S values, which could suggest systematic alteration of sulfur isotope values due to sulfur contamination or amino acid loss. For our Great Lakes proboscideans, the first approach was insufficient to identify sulfur isotope alteration, but the second and third approaches led to the exclusion of 4 samples with probable alteration. Great Lakes proboscideans had lower <em>δ</em><sup>34</sup>S values than recent taxa from the same region, and the <em>δ</em><sup>34</sup>S of mastodons tended to be lower than those of mammoths.

Two sediment sequences were obtained at the Ageröd peatland to compare the sediment stratigraphy with a previous sequence obtained in 1960 to detect any modern-day changes and to establish the Holocene environmental development in the area. To clarify the timing of ceased peat-cutting activities, dendrochronological analysis was performed on trees growing on the peatland. The results indicate that the lake transitioned into first a fen stage and later a raised bog stage, at about 7300 cal BP and 6500 cal BP, respectively. Furthermore, the dendrochronological analysis indicates that peat cutting ceased at least before 1960 in the sampled areas. Depending on e.g. hydrological conditions and human impact, the potential for preservation of organic remains varies greatly within the Rönneholm-Ageröd peatland complex. After peat-cutting activities ceased at the Ageröd peatland, the area was abandoned, without being restored to its original state and the drainage systems were left open but without maintenance. Our results show that these drainage ditches are still effective at the Ageröd peatland, which contributes to an active loss of peat at the top of the stratigraphic sequence. This causes the youngest formed peat layers to degrade, in turn, exposing older layers and reducing the buffer zone above the preserved organic cultural heritage from the lake-phase of the wetland with their destruction. To increase the understanding of modern-day processes affecting the preservation of organic remains in peatlands, continued monitoring and measuring of the peatland preservation status is needed in areas with archaeological deposits. We predict that if we fail to take action and establish a routine for finding and mitigating ongoing wetland degradation, the organic cultural and environmental heritage in them will, in the not-too-distant future, collapse and irrevocably deteriorate.</div></div>","PeriodicalId":101053,"journal":{"name":"Quaternary Environments and Humans","volume":"2 6","pages":"Article 100039"},"PeriodicalIF":0.0,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142698827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finally, I propose a means of moving forward, suggesting we move from a world where p &lt; 0.05 is considered a binary threshold for conclusive results, to a more nuanced practice where different gradients, down to p &lt; 0.003, are interpreted as increasingly suggestive evidence – provided that findings are supported by additional, transparently reported corroborative data.</div></div>","PeriodicalId":101053,"journal":{"name":"Quaternary Environments and Humans","volume":"2 6","pages":"Article 100041"},"PeriodicalIF":0.0,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142698829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
