- A 1000-year-old case of Klinefelter's syndrome diagnosed by integrating morphology, osteology, and geneticsPublication . Roca-Rada, Xavier; Tereso, Sofia; Rohrlach, Adam B.; Brito, Andre; Williams, Matthew P.; Umbelino, Cláudia; Curate, Francisco; Deveson, Ira W.; Souilmi, Yassine; Amorim, Antonio; Carvalho, Pedro C.; Llamas, Bastien; Teixeira, Joao C.The skeleton of a human being buried over 1000 years ago, in the medieval archaeological site of Torre Velha, in north-eastern Portugal, was referred to us for analysis and investigation
- 40 years of excavations at Mitoc–Malu Galben (Romania): changing fieldwork methodologies and implications for the comparability of archaeological assemblagesPublication . Noiret, Pierre; Libois, Timothée; Chirica, Vasile; Branscombe, Tansy; Murphree, William; Bosch, Marjolein D.; Haesaerts, Paul; Nigst, Philip R.Mitoc-Malu Galben (Romania) is one of the key-sites for the Upper Palaeolithic in Eastern Europe, with abundant Upper Palaeolithic archaeological layers embedded in a similar to 14 meters long loess-palaeosol sequence. The excavations in 1978-1990 yielded rich remains of Aurignacian and Gravettian workshops. From 1992 to 1995, an international collaboration helped better define their stratigraphical position, age, and typological characteristics. Since 2013, our team has conducted new fieldwork focusing on interdisciplinary study of site formation processes and a detailed technological study of the lithic artefacts. These different excavation phases have employed quite substantially different fieldwork methodologies. Here, we explore the impact of the changing excavation methodologies on the comparability of the generated assemblages by analyzing the frequency of bladelets among the elongated blanks as well as the length distribution of elongated blanks. Our preliminary study allows us to suggest that some of the assemblages seem to be influenced by the fieldwork methodology employed by each excavation phase, but more studies are needed to start to understand how the assemblages are biased.
- A C-14 chronology for the Middle to Upper Palaeolithic transition at Bacho Kiro Cave, BulgariaPublication . Fewlass, Helen; Talamo, Sahra; Wacker, Lukas; Kromer, Bernd; Tuna, Thibaut; Fagault, Yoann; Bard, Edouard; McPherron, Shannon P.; Aldeias, Vera; Maria, Raquel; Martisius, Naomi L.; Paskulin, Lindsay; Rezek, Zeljko; Sinet-Mathiot, Virginie; Sirakova, Svoboda; Smith, Geoffrey M.; Spasov, Rosen; Welker, Frido; Sirakov, Nikolay; Tsanova, Tsenka; Hublin, Jean-JacquesThe stratigraphy at Bacho Kiro Cave, Bulgaria, spans the Middle to Upper Palaeolithic transition, including an Initial Upper Palaeolithic (IUP) assemblage argued to represent the earliest arrival of Upper Palaeolithic Homo sapiens in Europe. We applied the latest techniques in C-14 dating to an extensive dataset of newly excavated animal and human bones to produce a robust, high-precision radiocarbon chronology for the site. At the base of the stratigraphy, the Middle Palaeolithic (MP) occupation dates to >51,000 yr bp. A chronological gap of over 3,000 years separates the MP occupation from the occupation of the cave by H. sapiens, which extends to 34,000 cal bp. The extensive IUP assemblage, now associated with directly dated H. sapiens fossils at this site, securely dates to 45,820-43,650 cal bp (95.4% probability), probably beginning from 46,940 cal bp (95.4% probability). The results provide chronological context for the early occupation of Europe by Upper Palaeolithic H. sapiens. A new radiocarbon chronology for the Middle to Upper Palaeolithic transition at the Bulgarian site of Bacho Kiro reveals Homo sapiens-associated sediments as early as 46,940 yr bp.

- A lunate-triquetral coalition from a commingled funerary context from the Chalcolithic Perdigoes ditched enclosures of PortugalPublication . Godinho, Ricardo Miguel; Santos, Ana Luisa; Valera, António CarlosCarpal coalitions, resulting from a failure of separation of the cartilaginous precursors of the carpal bones during gestation, may be osseous or non-osseous. Even though lunate-triquetral coalitions are the most common of all carpal coalitions there is only one previous palaeopathological report of such a coalition. This study presents a non-osseous lunate-triquetral coalition found amongst the mostly cremated commingled bones from a Chalcolithic pit at Perdigoes (Portugal). The cremated bones show evidence of burning at varying but mostly at generally high temperatures. The perfect articulation between these right bones and pinpoint pitting in the lunate-triquetral joint were crucial for the identification of this congenital condition. Carpal coalitions are more frequent in African than European populations. Artifacts produced from ivory of African origin were found in Perdigoes, however it is not possible to establish the ancestry of this individual.
- A missing piece of the Papio puzzle: Gorongosa baboon phenostructure and intrageneric relationshipsPublication . Martinez, Felipe I.; Capelli, Cristian; Ferreira da Silva, Maria J.; Aldeias, Vera; Alemseged, Zeresenay; Archer, William; Bamford, Marion; Biro, Dora; Bobe, Rene; Braun, David R.; Habermann, Jörg M.; Luedecke, Tina; Madiquida, Hilario; Mathe, Jacinto; Negash, Enquye; Paulo, Luis M.; Pinto, Maria; Stalmans, Marc; Tata, Frederico; Carvalho, SusanaMost authors recognize six baboon species: hamadryas (Papio hamadryas), Guinea (Papio papio), olive (Papio anubis), yellow (Papio cynocephalus), chacma (Papio ursinus), and Kinda (Papio kindae). However, there is still debate regarding the taxonomic status, phylogenetic relationships, and the amount of gene flow occurring between species. Here, we present ongoing research on baboon morphological diversity in Gorongosa National Park (GNP), located in central Mozambique, south of the Zambezi River, at the southern end of the East African Rift System. The park exhibits outstanding ecological diversity and hosts more than 200 baboon troops. Gorongosa National Park baboons have previously been classified as chacma baboons (P. ursinus). In accordance with this, two mtDNA samples from the park have been placed in the same mtDNA Glade as the northern chacma baboons. However, GNP baboons exhibit morphological features common in yellow baboons (e.g., yellow fur color), suggesting that parapatric gene flow between chacma and yellow baboons might have occurred in the past or could be ongoing. We investigated the phenostructure of the Gorongosa baboons using two approaches: 1) description of external phenotypic features, such as coloration and body size, and 2) 3D geometric morphometric analysis of 43 craniofacial landmarks on 11 specimens from Gorongosa compared to a pan-African sample of 352 baboons. The results show that Gorongosa baboons exhibit a mosaic of features shared with southern P. cynocephalus and P. ursinus griseipes. The GNP baboon phenotype fits within a geographic clinal pattern of replacing allotaxa. We put forward the hypothesis of either past and/or ongoing hybridization between the gray-footed chacma and southern yellow baboons in Gorongosa or an isolation-by-distance scenario in which the GNP baboons are geographically and morphologically intermediate. These two scenarios are not mutually exclusive. We highlight the potential of baboons as a useful model to understand speciation and hybridization in early human evolution. (C) 2019 Elsevier Ltd.

- A preliminary study on ochre sources in Southwestern Germany and its potential for ochre provenance during the Upper PaleolithicPublication . Velliky, Elizabeth C.; Barbieri, Alvise; Porr, Martin; Conard, Nicholas J.; MacDonald, Brandi LeeThe use of mineral pigments, specifically iron-oxide rich mineral pigments called ochre, has been put forward as a key element in the development of symbolic and non-utilitarian behaviors in human evolution. However, the processes of ochre procurement, trade and use are difficult to conceptualize without the identification and characterization of the sources where these materials were acquired. We present the results of geochemical analyses of ochre source samples collected from the Swabian Jura, Black Forest, and other localities in southern and eastern Germany. The goal of this study was to build the groundwork for future investigations on the range of ochre behaviors at archaeological sites in the region. We aimed to determine whether specific ochre outcrops could be differentiated based on their geochemical signatures. Using data from Neutron Activation Analysis (NAA), we were able to determine that the ochre source regions exhibit greater source inter-variability than infra-variability when observed using a range of statistical techniques, therefore satisfying the provenance postulate. Furthermore, the data provide the foundation for a Central European database of ochre sources to allow the comparison of ochres from different regions to archaeological ochres from important nearby and perhaps distant sites.
- The adaptive role of bark in the diet of budongo chimpanzees (Pan troglodytes schweinfurthii)Publication . Freymann, E.; Badihi, G.; Hobaiter, C.; Huffman, M. A.; Muhumuza, G.; Orbell, S.; Sempebwa, D.; Robert Yikii, E.; Zuberbühler, K.; Carvalho, SusanaThe ingestion of bark has been observed across the animal kingdom and is well documented in free-ranging chimpanzees. Thus far, the best-supported hypothesis for the adaptive function of this behavior is the fallback food hypothesis, which asserts that chimpanzees consume bark and cambium when preferred foods are scarce. However, alternative explanations exist, including the essential nutrient and mineral hypothesis, the self-medication hypothesis, and the stressed-tree hypothesis. We tested whether the fallback food hypothesis can explain bark-feeding across two communities of Eastern chimpanzees (Pan troglodytes schweinfurthii) in the Budongo Forest, Uganda. We used 13 years of the site's long-term behavioral data, 5 years of food availability data, and 8 months of direct and indirect observations. We also conducted eight 400-m line transects to collect data on the distribution of tree species across community home ranges. We employed several analyses, including Pearson correlation tests, qualitative comparisons of descriptive data and heat maps, and interpretation of behavioral anecdotes. We found varying patterns of bark-feeding seasonality across tree species, with bark-feeding on several species showing no correlation with food scarcity. We also identified differences in the amounts of bark targeted between tree species and report anecdotal evidence of chimpanzees prioritizing bark over high-value foods. Lastly, we found that bark-feeding on certain species disproportionally occurs far from community core areas, despite relative abundance of these species within the home range. As a result, we argue that the fallback food hypothesis cannot explain bark-feeding across all tree species. Instead, we present supporting evidence for several alternative hypotheses, including self-medication, thereby challenging the widely accepted function of this behavior.
- Addressing human mobility in Iberian Neolithic and Chalcolithic ditched enclosures: The case of Perdigoes (South Portugal)Publication . Carlos Valera, António; Zalaite, I; Maurer, A. F.; Grimes, V; Silva, A. M.; Ribeiro, S.; Santos, J. F.; Barrocas Dias, C.To access the role of mobility in the social trajectory of Late Neolithic and Chalcolithic societies in the South of Portugal (Southwest Iberia) a project was design to address the human, animal and object/raw material flow present at Perdigoes enclosure. Perdigoes, located in the inner Alentejo region, has a long chronology from Late Middle Neolithic to Late Chalcolithic/Early Bronze Age (middle 4th and 3rd millennium BC). It is a large complex of ditched enclosures (with at least 16 ditches), presenting several funerary contexts, an abundance of faunal remains and significant concentrations of exogenous materials in tombs. In this study human and animal mobility are addressed through Sr-87/Sr-86 isotopic analysis. 69 individuals dating from Late Neolithic and Chalcolithic, with provenance from 9 different archaeological contexts inside the enclosures (tombs, ditches and pits) were analysed. Human data are presented along with previously published strontium isotope ratios from fauna (n = 28; Canis familiaris, Bos taurus, Sus sp., Ovis/Capra, Cervus elaphus, Equus sp.) from the same chronological range and several contextual provenances (Zalaite et al., 2018). Plant samples (n = 20) that cover local and peripheral lithologies were used for establishing local bioavailable strontium isotope ranges. To compare with the Perdigoes results, 9 human samples from 3 megalithic monuments (Cebolinhos 1, Comenda 1 and Vidigueiras 2) of the local settlement network were also analysed. The results show a significant scaled mobility of humans and animals in Perdigoes, a contextual variation between the funerary contexts within the site and a significant contrast with the individuals from local megalithic monuments. These results, combined with other archaeological data at the site, agree with the interpretation of the site as a large aggregation centre integrated in large scale interaction networks.
- An experimental approach on dynamic occlusal fingerprint analysis to simulate use-wear localisation and development on stone toolsPublication . Rausch, Hannah; Marreiros, Joao; Kullmer, Ottmar; Schunk, Lisa; Gneisinger, Walter; Calandra, IvanInformation about the use of stone tools in the past is encoded in the wear patterns left on their surface; however, post-depositional processes can modify and obstruct these traces. One aim in the field of lithic functional analysis is to develop methods to detect and quantify these traces on stone tools. The occlusal fingerprint analysis (OFA) is a well-established method in dental wear studies to virtually simulate dental occlusal (contact between teeth) stroke movements and thus locate and quantify the sequential contact between opposing tooth crowns. Reaching across disciplines, we conducted controlled experiments to test the applicability of the OFA method on stone tools to address the challenge of use-wear quantification and localisation, and therefore the identification of post-depositional wear. Our findings reveal a clear overlap between zones of experimentally produced use-wear and OFA-calculated contact areas. We demonstrate OFA as a potential method to generate models of multiscale use-wear that can be used as references on experimental tools to identify post-depositional surface modifications on stone tool artefacts.
