The dispersal of domestic cats from North Africa to Europe around 2000 years ago
-
The domestic cat (Felis catus) descends from the African wildcat Felis lybica lybica. Its global distribution alongside humans testifies to its successful adaptation to anthropogenic environments. Uncertainty remains regarding whether domestic cats originated in the Levant, Egypt, or elsewhere in the natural range of African wildcats. The timing and circumstances of their dispersal into Europe are also unknown. In this study, the analysis of 87 ancient and modern cat genomes suggests that domestic cats did not spread to Europe with Neolithic farmers. Conversely, they were introduced to Europe around 2000 years ago, probably from North Africa. In addition, a separate earlier introduction (first millennium before the common era) of wildcats from Northwest Africa may have been responsible for the present-day wild population in Sardinia. Tracing the origins of domestic cats (Felis catus) has been limited by a lack of ancient DNA for these animals, as well by their morphological similarity to the African wildcat (F. lybica lybica) and European wildcat (F. sylvestris). De Martino et al. generated low- to medium-coverage genomes for 87 ancient, museum, and modern cats (see the Perspective by Losos). They found that domestic cats are most genetically similar to African wildcats, although there has been widespread gene flow between wild and domestic populations. European samples that cluster with domestic cats only appear in the 1st century CE, suggesting a later dispersal of domestic cats than previously thought. Although broader sampling is needed, this study shows the complexity of population dynamics that is often revealed when looking beyond mitochondrial DNA.

The Dispersal of the Domestic Cat: Paleogenetic and Zooarcheological Evidence
-
Domestication is one of the most interesting and challenging processes in human and animal evolution. The fundamental change in subsistence strategies from hunting and gathering to farming that took place for the first time in the Levant more than ten thousand years ago profoundly changed human culture and biology, and set the groundwork for population growth, migrations, the rise of civilizations, and wealth disparities (Bocquet-Appel 2011; Gignoux, Henn, and Mountain 2011; Kohler et al. 2017).

The distinction of isolated bones from plaice (Pleuronectes platessa), flounder (Platichthys flesus) and dab (Limanda limanda): a description of the diagnostic characters
-
The osteology of 38 skeletal elements is investigated in plaice, dextral and sinistral flounder, and dab with the aim of defining diagnostic characters that allow species identification of isolated bones from archaeological excavations. Five of these 38 skeletal elements have been mentioned in the literature as being diagnostic, but they appear to be unreliable for identification. All other elements allow identification, although only 23 permit the recognition of all three species. The individual bone elements and their diagnostic criteria are depicted and described in detail. Attention is paid to individual variation, and, when relevant, size-related morphological changes are also described. The keys that are developed for the various elements are finally tested on a large flatfish bone assemblage from an archaeological site. On the basis of these results, the success rate of the identifications for the various bones is discussed. Possible strategies for identification work on this group are suggested that take into account the extent of the reference collection, the time spent on the identifications and the experience needed in comparative osteology of these flatfish.

The dynamics of ant mosaics in tropical rainforests characterized using the Self-Organizing Map algorithm
-
Ants, the most abundant taxa among canopy-dwelling animals in tropical rainforests, are mostly represented by territorially-dominant arboreal ants (TDAs) whose territories are distributed in a mosaic pattern (arboreal ant mosaics). Large TDA colonies regulate insect herbivores, with implications for forestry and agronomy. What generates these mosaics in vegetal formations, which are dynamic, still needs to be better understood. So, from empirical research based on three Cameroonian tree species (Lophira alata, Ochnaceae; Anthocleista vogelii, Gentianaceae; and Barteria fistulosa, Passifloraceae), we used the Self-Organizing Map (SOM, neural network) to illustrate the succession of TDAs as their host trees grow and age. The SOM separated the trees by species and by size for L. alata, which can reach 60 m in height and live several centuries. An ontogenic succession of TDAs from sapling to mature trees is shown, and some ecological traits are highlighted for certain TDAs. Also, because the SOM permits the analysis of data with many zeroes with no effect of outliers on the overall scatterplot distributions, we obtained ecological information on rare species. Finally, the SOM permitted us to show that functional groups cannot be selected at the genus level as congeneric species can have very different ecological niches, something particularly true for Crematogaster spp. which include a species specifically associated with B. fistulosa, non-dominant species and TDAs. Therefore, the SOM permitted the complex relationships between TDAs and their growing host trees to be analyzed, while also providing new information on the ecological traits of the ant species involved.

The earliest evidence for deformation of livestock horns: The case of Predynastic sheep from Hierakonpolis, Egypt
-
Archaeozoological evidence for the modification of sheep horns during Egypt's Predynastic period was uncovered at Hierakonpolis, Upper Egypt. At HK6, the site's so-called elite cemetery, a grave, which was part of a larger mortuary complex dated to around 3700 BC, contained at least 6 large, castrated male sheep. One individual was polled, while four others were of the corkscrew-horn type, but their horns were not oriented in the natural, lateral direction. Instead, the horns had been intentionally manipulated to grow upwards and in three cases this resulted in upright, parallel horns. While comparable practices are well documented in Africa in cattle through both modern ethnographic observations and archaeozoological studies of material from third millennium BC Nubia (in Kerma, Sudan), the Hierakonpolis sheep provide the oldest evidence for horn modification of livestock, and the first demonstration of the practice applied to sheep. When describing the skulls particular attention is paid to the pathological traces and deformities, i.e. constrictions on the horn cores, holes at the horn core bases, and deformations of the frontals. In order to assess the possible methods used in Predynastic Hierakonpolis to redirect the horns, these observations are compared with ethnographic and archaeozoological data from the literature. Finally, the possible reasons why these sheep were modified are also discussed. This study indicates that Predynastic Egyptians were already familiar with horn modelling techniques and confirms that this practice has a long history in the Nile Valley.

The Early Carboniferous progymnosperm Protopitys: new data on vegetative and fertile structures, and on its geographic and stratigraphic distribution
-
We review progress made during the last 25 years in our understanding of the Protopityales, Early Carboniferous plants belonging to the extinct group of the progymnosperms. Recent studies support previous observations that the only genus of this order, Protopitys, included large arborescent plant with trunks up to 1 m in diameter. All branch orders had an oval eustele, secondary xylem with small rays and tracheid pitting ranging from circular bordered to scalariform bordered, and vascular traces to lateral appendages emitted in an alternate to subopposite distichous arrangement. Leaf morphology remains unknown. New material also confirms that fertile organs of Protopitys consist of branching systems bearing elongated sporangia terminally. Spores have a perispore and range in two size groups, which has been interpreted as a primitive stage of heterospory. The dense wood and fertile parts of Protopitys are comparable to those of the aneurophytalean progymnosperms of the Devonian, but Protopitys is distinct by its eustelic primary vascular system, and its affinities are still uncertain. The genus is now documented from at least nine localities in Europe, North America and Australia. Recent discoveries also indicate that it was present through the whole Mississippian, from the middle Tournaisian to the Serpukhovian.
