“…In a previous study performed on the same sample, allometry was demonstrated as statistically significant for all the bones except forelimb phalanges, coxal and metatarsal bones (Hanot et al. ). The results also revealed that the breeds did not share the same allometry, which, coupled with the small size of the sample, would normally make it impossible to remove allometric effects (Klingenberg, ).…”

The relationships between the different component parts of organisms, such as the sharing of common development or function, produce a coordinated variation between the different traits. This morphological integration contributes to drive or constrain morphological variation and thus impacts phenotypic diversification. Artificial selection is known to contribute significantly to phenotypic diversification of domestic species. However, little attention has been paid to its potential impact on integration patterns. This study explores the patterns of integration in the limb bones of different horse breeds, using 3D geometric morphometrics. The domestic horse is known to have been strongly impacted by artificial selection, and was often selected for functional traits. Our results confirm that morphological integration among bones within the same limb is strong and apparently partly produced by functional factors. Most importantly, they reveal that artificial selection, which led to the diversification of domestic horses, impacts covariation patterns. The influence of selection on the patterns of covariation varies along the limbs and modulates bone shape, likely due to a differential ligament or muscle development. These results highlight that, in addition to not being constrained by a strong morphological integration, artificial selection has modulated the covariation patterns according to the locomotor specificities of the breeds. More broadly, it illustrates the interest in studying how micro-evolutionary processes impact covariation patterns and consequently contribute to morphological diversification of domestic species.

Identifying marsupials from Australian archaeological sites: current methodological challenges and opportunities in zooarchaeological practice

We review current zooarchaeological practice in Australia, identifying major research themes and key methodological gaps where opportunities exist for the development of Australian zooarchaeology as a discipline. We demonstrate that marsupial remains form a significant component of Australian zooarchaeological assemblages, yet high resolution taxonomic identification of these remains continues to prove challenging, owing to a combination of high species diversity and few resources which provide diagnostic criteria for discriminating morphologically similar, but ecologically variable taxa. The lack of robust protocols for discriminating marsupial taxa significantly impacts our ability to effectively integrate zooarchaeological data into broader narratives of Aboriginal colonisation, resilience and adaptation across Australia. Publication of identification protocols would help refine and standardise diagnostic criteria used between analysts, improve the methodological transparency of zooarchaeological analysis and provide resources for the training of a new generation of specialists. A range of opportunities currently exist, utilising qualitative and quantitative techniques, to significantly contribute towards the methodological robustness of zooarchaeological practice in Australia.

The emergence of pastoralism and animal husbandry has been a critical point in the history of human evolution. Beyond profound behavioural changes in domesticated animals compared to wild ones, characterising the morphological changes associated with domestication process remains challenging. Because reindeer (Rangifer tarandus) can be considered to still be in the early phases of the domestication process, the study of modern populations provides a unique opportunity to examine the impact of captivity and selective breeding on skeletal changes. In this work, we investigated the morphological changes in long limb bone cross‐sections using 137 wild and domestic reindeer individuals bred in free‐range, in captivity or used for racing and pulling. The shape and shaft cortical thickness of the six long limb bones (i.e., humerus, radioulna, metacarpal, femur, tibia and metatarsal) were measured using a 2D‐geometric morphometrics approach taking into account subspecies, sex, body mass and lifestyle differences. These bones are important to understanding functional morphological changes because they can provide information on feeding and locomotor behaviours, as well as on body propulsion and weight bearing. Apart from the effects of taxonomy, etho‐ecology and sex, we have found that captivity and selection induced important variations in the size and body mass of modern reindeer. Our results also showed that patterns of variation in cortical bone thickness of long limb bone cross‐sections were strongly impacted by body mass and human‐imposed restrictions in roaming. This demonstrates that bone cross‐sections can provide information on changes in locomotor, reproductive and feeding behaviours induced by the domestication process. These results are valuable not only for (paleo) biologists studying the impact of captivity and selection in ungulates but also for archaeologists exploring the origins of domestication and early herding strategies.
