Innovations relevant to human evolution often involve subsistence technology, which can affect the success of individual groups, and Homo sapiens in general. However, Palaeolithic technologies include more than just hunting tools, and a proper understanding of hunter-gatherer ways of living requires knowledge of the organisation of diverse tasks and activities, including the manufacture and maintenance of tools and other equipment. One central aspect of technological evolution is the development of tool hafting [1, 2], which is not only restricted to hunting and gathering implements, but also affects so-called domestic tool categories. We present the results of an on-going project that focuses on hafting and use of stone tools in the Upper Palaeolithic through detailed functional analysis of selected assemblages from European key sites (Hohle Fels, Abri Pataud, Maisières-Canal), which have yielded rich lithic and organic assemblages from secure chronological contexts. Here the focus is on classic Upper Palaeolithic tool categories, such as endscrapers and burins, from the Gravettian and Magdalenian levels of the cave site Hohle Fels (Germany) [3, 4]. We suggest that domestic tools can offer a valuable source material, since for most of them, hafting is not a necessity as it is for spear and arrow tips. An increase in hafting implies an increase in time investment, which has implications for task organisation and specialisation. The Hohle Fels assemblage offers an interesting case study for temporal changes (or continuity) in the frequency and techniques of tool hafting. The projectile technology shows a clear shift from the Gravettian to the Magadalenian, marked by the introduction of a microlithic technology (backed bladelets). For other tool categories, the changes seem more subtle. Our goal is to characterise the tools used in manufacture and maintenance tasks, and to evaluate whether the Gravettian to Magdalenian transition witnesses changes in tool design and use that go beyond hunting equipment. The observed differences between tool classes and time periods are explained with a reference to details of tool use, such as the rate of edge wear development and stone tool exhaustion, as well as shifts in treatment of organic raw materials. The results suggest that domestic tools can aid in understanding long-term technological evolution, and create a baseline against which we can (re)assess the role of shifts observed in technologies that are more susceptible to morphological change, such as projectiles.

One of the 'grand challenges' in modern biology is to understand the genetic basis of phenotypic diversity within and among species. Thousands of years of selective breeding of domestic animals has created a diversity of phenotypes among breeds that is only matched by that observed among species in nature. Domestic animals therefore constitute a unique resource for understanding the genetic basis of phenotypic variation. When the genome sequences of domestic animals become available the identification of the mutations that underlie the transformation from a wild to a domestic species will be a realistic and important target.

The “Arabian babblers” are observed in the Neguev desert for more than 40 years. These birds live in cooperative groups. They offer presents to feed each other, they endanger themselves by mobbing raptors or by coming to the rescue of group members. They play and they also often dance together. All these behaviors have received various and controversial interpretations in the scientific literature. Following the actual field’s work, one may observe that these interpretations are closely linked to the way scientists observe the birds, or even deal with them. Different practices not only construe but actually “produce” different birds. Roughly said, some of the observers take a “subjectivist” stance and interact with the birds, the other one takes an “objectivist” stance, and keeps distance from them. Each of these practices has different effects, on the birds, and on the theories. These birds therefore appear just at the edge of the categories of wild/domesticated/feral, their identity seeming to change accordingly to the ethologist who observes them. [less ▲]

Background: The contralateral shoulder is often used as a reference when evaluating a pathological shoulder. However literature provides contradictory results regarding the symmetry of the scapular pattern in a healthy population. We assume that several factors including the gender and the type of motion may influence the scapula bilateral symmetry. Method: The dominant and non dominant shoulders of two populations of men and women composed of 11 subjects each were evaluated for three distinct motions: flexion in the sagittal plane, abduction in the frontal plane and gleno-humeral internal/external rotation with the arm abducted at 90°. Posture, kinematic and range of motion were studied separately. Results: Asymmetries are observed for motions performed in the frontal and sagittal plane but not for the internal/external rotation with the arm abducted at 90°. Multiplane asymmetries are observed for the male population, whereas asymmetries for the female one are mainly uniplanar. For both men and women, the scapula has a larger upward rotation on the dominant side. For men, a larger posterior tilt is also observed. The asymmetries mainly originate in the scapula kinematic and not in its original posture. Discussion: Even if the asymmetries are not large in terms of amplitude (inferior to 5°), one should be aware of their existence and the influence of the composition of the studied population when using the contralateral shoulder as a reference.

Gut content examination and trophic markers (fatty acids, stables isotopes of C and N) were combined to delineate the diet of the dominant species of amphipods from Mediterranean Posidonia oceanica seagrass meadows and to highlight trophic diversity among this community. Our results indicate that, although all dominant species heavily relied on macroalgal epiphytes, considerable interspecific dietary differences existed. Carbon stable isotope ratios notably showed that some of the amphipod species favored grazing on epiphytes from leaves or litter fragments (Apherusa chiereghinii, Aora spinicornis, Gammarus aequicauda), while others like Dexamine spiniventris preferred epiphytes from rhizomes. The remaining amphipods (Caprella acanthifera, Ampithoe helleri and Gammarella fucicola) readily consumed both groups. In addition, SIAR modeling suggested that most species had a mixed diet, and relied on several food items. Fatty acid analysis and gut contents revealed that contribution of microepiphytic diatoms and of benthic and suspended particulate organic matter to the diet of amphipods were anecdotal. None of the examined species seemed to graze on their seagrass host (low 18:2(n-6) and 18:3(n-3) fatty acids contents), but G. aequicauda partly relied on seagrass leaf detritus, as demonstrated by the lesser 13C-depletion of their tissues. Overall, our findings suggest that amphipods, because of their importance in transfers of organic matter from primary producers and detritus to higher rank consumers, are key-items in P. oceanica associated food webs.

We construct simple portfolios of hedge funds whose performance characteristics dominate those of funds of funds using three different measures: the alpha, the Sharpe ratio and the Information ratio. Portfolios made up of non-directional funds with the highest Information ratios and/or Sharpe ratios are likely to exhibit a significant amount of persistence and continue to dominate the best funds of funds on all three performance measures. The large risk exposure of directional hedge fund strategies, however, makes them less likely to dominate funds of funds, even when combined with non-directional hedge funds strategies. Overall, these results seem to imply that the extra layer of fees paid to fund of fund managers are largely unmerited, as we can create portfolios of funds, using simple portfolio construction rules and readily available market information, that greatly outperform the best Fund of Funds.
