A catalyst meeting on sexual selection studies was held in July 2013 at the facilities of the National Evolutionary Synthesis Center (NESCent) in Durham, NC. This article by a subcommittee of the participants foregrounds some of the topics discussed at the meeting. Topics mentioned here include the relevance of heritability estimates to assessing the presence of sexual selection, whether sexual selection is distinct from natural selection, and the utility of distinguishing sexual selection from fecundity selection. A possible definition of sexual selection is offered based on a distinction between sexual selection as a frequency-dependent process and fecundity selection as a density-dependent process. Another topic highlighted is a deep disagreement among participants in the reality of good-genes, sexy-sons, and run-away processes. Finally, the status of conflict in political-economic theory is contrasted with the status accorded to conflict in evolutionary behavioral theory, and the professional responsibility of sexual-selection workers to consider the ethical dimension of their research is underscored.

Abstract This essay pioneers a critical approach to place naming in early America, which offers new insight into the evolving definition of plantation. In early seventeenth-century England, planting was understood as a public effort to establish new commonwealths. Only gradually around the Atlantic world did plantations become predominantly associated with private places producing staple crops with enslaved labor. This essay uses the radically underutilized evidence of place-names to explore how this slippage occurred on the ground, and the way it shaped, and was shaped by, the individuals who embraced the status of “planter.” The names that individuals gave to the places they called plantations reveal how they perceived the plantation and the political, economic, and social relations it structured. By analyzing data from nearly 5,000 named tracts of land patented in four Maryland counties between 1634 and 1750, this essay charts the changing popularity of distinct elements within plantation names, including geographic descriptors, affects of the landowner, and European place-names. It reveals there was no straightforward rush to carve up the land into privatized commercial units. Instead, individuals initially structured plantations around communal frameworks defined variously by manorialism, urban civic traditions, and shared geographic lexicons. As the tobacco economy consolidated into the hands of a slave-owning class, plantation names reframed places as subjective manifestations of planter identities. These conclusions adjust our understanding of the transition to capitalism and slavery in Maryland and they also offer a blueprint for a broader toponymy of the plantation in the Atlantic world.

AbstractWhether sexual selection impedes or aids adaptation has become a pressing question in times of rapid environmental change and parallels the debate about how the evolution of individual traits impacts on population dynamics and viability. The net effect of sexual selection on population viability results from a balance between genetic benefits of “good genes” effects and costs of sexual conflict. Depending on how these facets of sexual selection are affected under environmental change, extinction of maladapted populations could either be avoided or accelerated. Here, we evolved seed beetles under three alternative mating regimes (polygamy, monogamy and male-limited selection) to disentangle the contributions of sexual selection, fecundity selection and male-female coevolution to individual reproductive success and population fitness. We compared these contributions between the ancestral environment and two new stressful environments (temperature and host plant shift). Evolution under polygamy resulted in the highest individual reproductive success in competitive context for both sexes. Moreover, females evolving only via sexual selection on their male siblings in the male-limited regime had similar reproductive success and higher fertility than females evolving under monogamy, suggesting that sexual selection on males had positive effects on female fitness components. Interestingly, male-limited sexual selection resulted in males that were robust to stress, compared to males from the two evolution regimes applying fecundity selection. We quantified the population-level consequences of this sex-specific adaptation and found evidence that costs of socio-sexual interactions were higher in male-limited lines compared to polygamous lines, and that this difference was particularly pronounced at elevated temperature to which males from the male-limited regime were more robust compared to their conspecific females. These results illustrate the tension between individual-level adaptation and population-level viability in sexually reproducing species and suggest that sex-specific selection can cause differences in environmental robustness that may impact population demography under environmental change.

Determinant Factor

In the Arab world, the recognized children of elite men and slave women could adopt the status of their father, ignoring the slave origin of the mother, owing to a system of patrilineal transmission. This regime co-existed with negative stereotypes toward slaves and blackness, despite the very fact that—as this study of notable families in Tetouan between 1859 and 1956 demonstrates—skin color was not the determinant factor to form part of this group. Rather, it was based on the social definition of filiation, leading to legal disputes between family members to delineate the boundaries of kinship.

AbstractThe emergence of the “4th Industrial Revolution,” i.e. the convergence of artificial intelligence, the Internet of Things, advanced materials, and bioengineering technologies, could accelerate socioeconomic insecurities and anxieties or provide beneficial alternatives to the status quo. In the post-Covid-19 era, the entities that are best positioned to capitalize on these innovations are large firms, which use digital platforms and big data to orchestrate vast ecosystems of users and extract market share across industry sectors. Nonetheless, these technologies also have the potential to democratize ownership, broaden political-economic participation, and reduce environmental harms. We articulate the potential sociotechnical pathways in this high-stakes crossroads by analyzing cellular agriculture, an exemplary 4th Industrial Revolution technology that synergizes computer science, biopharma, tissue engineering, and food science to grow cultured meat, dairy, and egg products from cultured cells and/or genetically modified yeast. Our exploration of this space involved multi-sited ethnographic research in both (a) the cellular agriculture community and (b) alternative economic organizations devoted to open source licensing, member-owned cooperatives, social financing, and platform business models. Upon discussing how these latter approaches could potentially facilitate alternative sociotechnical pathways in cellular agriculture, we reflect upon the broader implications of this work with respect to the 4th Industrial Revolution and the enduring need for public policy reform.

Writing and researching Southern Europe as a symbiotic area has always presented a challenging task. Historians and political scientists such as Stanley Payne, Edward Malefakis, Giulio Sapelli, and Roberto Aliboni have studied the concept of Southern Europe and its difficult paths to modernity. They have been joined by sociologists and anthropologists who have debated the existence of a Southern European paradigm in the nineteenth and twentieth centuries and the arduous transformation of the region's welfare systems, economic development, education and family structures. These scholarly attempts to understand the specificities of Southern Europe date back to the concerns of Western European Cold War strategists in the 1970s, many of whom were worried about the status quo of the region in the aftermath of the fall of the dictatorships. But this geographical and geopolitical definition of the area did not necessarily follow existing cultural, political and economic patterns. Once the Eurozone crisis hit in the 2000s these questions came back with renewed force but with even less conceptual clarity, as journalists and pundits frequently gestured towards vague notions of what they considered to be ‘Southern Europe’.

Narrative Syntax

AbstractIs there a ‚narrative syntax‘, i. e. a special grammar restricted to narrative fiction? Starting from this question which has been investigated since early structuralism, the paper focusses on grammatical characteristics of narrative discourse mode and their implications for a linguistic theory of narration. Its goal is two-fold: In a first step, the traditional accounts by Benveniste, Hamburger, Kuroda and recent typological studies are brought together in order to support the claim that the distinction between narrative and non-narrative discourse mode is a fundamental one that has consequences for the use of grammar. In a second step, I discuss three central questions within the intersection between narrative micro- and macro-structures, namely (i) the definition of narrativity, (ii) the status of the narrator, and (iii) the relation between narration and fictionality. In sum, the article argues that investigations on the ‘grammar of narration’ do not just offer insights into a specific text configuration next to others, but are deeply linked to fundamental theoretical questions concerning the architecture of language – and that the comparison between linguistic and narratological categories offers a potential for addressing them.
