Dental microwear (DMA) is a tool used for the palaeodiet reconstruction of animals in Archaeology. The use of this proxy on domestic ungulates provides valuable information to reconstruct livestock strategies, yet it presents several methodological limitations. Most studies have been carried out using low-magnification DMA and the interpretations often relied on comparisons with databases of extant wild ungulates. In addition, several studies have highlighted challenges in discerning diets in extant domestic caprines. In parallel, dental microwear texture analysis (DMTA) – a quantitative methodology based on 3D micro-texture height maps – has shown better discrimination. In this paper, we explore the capacity to distinguish four different management strategies of domestic goats (Capra hircus) and three species of wild ibexes (Capra nubiana, C. pyrenaica and C. ibex) using DMTA. Results revealed good discrimination among extant domestic goat populations and between wild and domestic goats. This new dataset was subsequently used to characterise the palaeodiet of archaeological goats from two Pre-Pottery Neolithic B sites in the southern Levant. Preliminary findings suggest evidence of human intervention in goats at least during the early 8th millennium BCE. In addition, incorporating various current management strategies has enhanced our understanding of early goat domestication in southern Levant. [ABSTRACT FROM AUTHOR]

Current evidence supports the idea that animal domestication occurred in multiple loci and at different time periods throughout the Near East rather than according to a single origin. In this scenario, the southern Levant is being increasingly considered as another presumed primary centre of goat domestication, alongside eastern Anatolia and the Zagros. Assessing the status (i.e. wild or domestic) of this animal in this region, however, is hampered by the difficulty of morphologically distinguishing domestic goats from their wild relatives. Diet reconstruction is a powerful approach to address this issue since the feeding of managed animals is partially controlled by their owners, unlike free-ranging wild populations. For the first time, we propose to contribute to this question through dental microwear texture analysis (DMTA) using confocal microscopy. Characterising how the dietary behaviour of extant wild and domestic goats is reflected in DMTA is critical. For this purpose, we constructed a reference collection composed of three wild goat species (19 Capra pyrenaica from the southern Iberian Peninsula , 12 Capra ibex from the Alps and 12 Capra nubiana from the Near East) and 15 domestic goats (Capra hircus) reared in an extensive system in Mediterranean scrubland areas. The preliminary results indicate that DMTA allows discrimination of the groups of extant goats. The results obtained were used to characterise the palaeodiet of 16 goats (Capra format aegagrus) from two key Early and Middle Pre-Pottery Neolithic B sites in the southern Levant: Kharaysin (Zarqa, Jordan, ca. 8800-7500 cal BC) and Qarassa (As-Suweyda, Syria, 8700-8200 cal BCE). The higher variability in archaeological goats could be an indicator of controlled feedings. It could also support the hypothesis about diverse and experimental management systems at the first steps of animal domestication. This paper shows the potential of this tool to address the process of early animal domestication. Following this initial work, the reference collection will include a broader spectrum of livestock management strategies and the archaeological corpus will be expanded through new samples during upcoming excavations and the integration of additional sites. • The southern Levant could have been another primary centre of goat domestication. • The morphological distinction between wild and domestic goats of Pre-Pottery Neolithic is not a straightforward task. • Palaeodiet reconstruction using dental microwear texture can shed new light since diet of managed goats was controlled by their owners. • Dental microwear texture differs between extant domestic and wild goats. • Microwear variability of goats from archaeological sites is higher than that of extant goats, which could indicate controlled feedings.

Archaeobotanical and genetic analysis of modern plant materials are drawing a complex scenario for the origins of cereal agriculture in the Levant. This paper presents an improved method for the study of early farming harvesting systems based on the texture analysis of gloss observed on sickle blades through confocal microscopy. Using this method, we identify different plant harvesting activities (unripe, semi-ripe and ripe cereal reaping and reed and other grass cutting) quantitatively and evaluate their change during the time when plant cultivation activities started and domesticated crops appeared in the Levant (12 800–7000 cal BC). The state of maturity of cereals when harvested shifted over time from unripe, to semi-ripe and finally to ripe. Most of these changes in harvesting techniques are explained by the modification of crops during the transition to agriculture. The shift in plant harvesting strategies was neither chronologically linear nor geographically homogeneous. Fully mature cereal harvesting becomes dominant around 8500 cal BC in the Southern Levant and one millennium later in the Middle Euphrates, which accords with the appearance of domestic varieties in the archaeobotanical record. The change in plant harvesting method fits better with the gradualist model of explanation of cereal agriculture than with the punctual one. • Confocal microscopy and texture analysis are used to analyze sickle gloss in experimental and archaeological tools. • Sickle gloss from harvesting different types of plants are discriminated. • Sickles from archaeological sites in the Levant dated from 12.000 to 7.000 cal BC are analyzed. • The long-term change in plant harvesting during the transition to agriculture in these regions is elucidated.
