On Modeling the Evolution of Hunter-Gatherer Decision-Making Systems

Models of both primate and hunter-gatherer decision-making systems are developed and their relative abilities potentially to detect certain classes of spatial distributions within a standardized environment are compared. It is demonstrated that in situations where language facilitates the pooling of information between individuals within a hunter-gatherer group, the group minimally need only to pool information with one central decision maker in order potentially to recognize all possible spatial distributions within a limited environment. On this basis alone, we would theoretically expect the presence of one-leader groups to be a fairly ubiquitous phenomenon among hunter-gatherers.     

Familia Sancti Martini: Domus ecclesiae on earth as it is in heaven

In the post-imperial world of sixth-century Gaul, the Church found itself competing for allegiance with strengthened local family groupings as well as royal households. In this milieu the fragmentation of power and the propensity for spoliation of church lands posed a severe problem for ecclesiastical survival. An answer might be found in a competing kindred structure: the family of the saint. Such an entity would have the benefit of building a support group for the Church that could cut across the existing family lines and thereby weaken their impact. As a voluntary association based on the celestial it would have the added benefit of being a familia everlasting, and endlessly elastic.The works of Gregory of Tours contain such an idea built around his patronus, St Martin. Gregory's preface to Book 5 of his History, and his frequent pleas against feuding, show his concern as to how the familia Sancti Martini could perform an annealing function for society, mitigate the more rebarbative elements of the feud, and leave the Church in a strengthened position in society.     

Marriage as a Marker of Secular Inclusion? Oral History and Lesbian and Gay Narratives on Marriage in Contemporary Australia

Same‐sex marriage has been one of the most widely discussed social issues in contemporary Australia for some time. In late 2017, after holding a contentious national postal survey that year, the Australia government introduced legislation allowing same‐sex couples to marry. This article draws on a major national lesbian and gay oral history project conducted in partnership with the National Library of Australia between 2012 and 2015, when discussions of same‐sex marriage were becoming increasingly widespread. It investigates the way interview subjects incorporated marriage into their narratives. In doing so, it highlights how understandings of marriage — both amongst lesbian and gay people and heterosexual people — have shifted and evolved over time. While some subjects saw marriage as a somewhat outdated, religious, and patriarchal concept, many others invested personal significance in the institution, arguing that allowing gay men and lesbians access to marriage would be a strong symbol of social progress and equality in a secular society. We conclude with one young interviewee who had managed to reconcile his faith with his sexuality and desire for marriage equality.     

Disparity Despite Diversity: Social Injustice in New York City's Urban Agriculture System

Many studies have documented the benefits of urban agriculture, including increased food access, job creation, educational opportunities, and green space. A focus on its social benefits has fed an association of urban agriculture with social justice, yet there is a distinction between alleviating symptoms of injustice (such as disparate access to food or environmental amenities) and disrupting structures that underlie them. Despite its positive impacts, urban agriculture systems may reinforce inequities that practitioners and supporters aim to address. This paper reports findings from a 2‐year study of urban agriculture in New York City, which found race‐ and class‐based disparities among practitioners citywide. Using the lens of critical race theory, it argues that a failure to examine urban agriculture's role in either supporting or dismantling unjust structures may perpetuate an inequitable system. The paper concludes with recommendations for urban agriculture supporters and scholars to help advance social justice at structural levels.     

Reduced Population Variance in Strontium Isotope Ratios Informs Domesticated Turkey Use at Chaco Canyon,New Mexico,USA

Traditionally, strontium isotopes (⁸⁷Sr/⁸⁶Sr) have been used as a sourcing tool in numerous archaeological artifact classes. The research presented here demonstrates that ⁸⁷Sr/⁸⁶Sr_bioapatite ratios also can be used at a population level to investigate the presence of domesticated animals and methods of management. The proposed methodology combines ecology, isotope geochemistry, and behavioral ecology to assess the presence and nature of turkey (Meleagris gallopavo) domestication. This case study utilizes ⁸⁷Sr/⁸⁶Sr_bioapatite ratios from teeth and bones of archaeological turkey, deer (Odocoileus sp.), lagomorph (Lepus sp. and Sylvilagus sp.), and prairie dog (Cynomys sp.) from Chaco Canyon, NM, USA (ca. A.D. 800–1250). Wild deer and turkey from the southwestern USA have much larger home ranges and dispersal behaviors (measured in kilometers) when compared to lagomorphs and prairie dogs (measured in meters). Hunted deer and wild turkey from archaeological contexts at Chaco Canyon are expected to have a higher variance in their ⁸⁷Sr/⁸⁶Sr_bioapatite ratios, when compared to small range taxa (lagomorphs and prairie dogs). Contrary to this expectation, ⁸⁷Sr/⁸⁶Sr_bioapatite values of turkey bones from Chacoan assemblages have a much lower variance than deer and are similar to that of smaller mammals. The sampled turkey values show variability most similar to lagomorphs and prairie dogs, suggesting the turkeys from Chaco Canyon were consuming a uniform diet and/or were constrained within a limited home range, indicating at least proto-domestication. The population approach has wide applicability for evaluating the presence and nature of domestication when combined with paleoecology and behavioral ecology in a variety of animals and environments.
