Carnivory, Coevolution, and the Geographic Spread of the Genus Homo   总被引:1,自引:0,他引:1  
This review traces the colonization of Eurasia by hominids some 1,700,000 years ago and their subsequent evolution there to 10,000 years ago from a carnivorous perspective. Three zooarchaeological trends reflect important shifts in hominid adaptations over this great time span: (1) increasing predation on large, hoofed animals that culminated in prime-adult–biased hunting, a predator–prey relationship that distinguishes humans from all other large predators and is a product of coevolution with them; (2) greater diet breadth and range of foraging substrates exploited in response to increasing human population densities, as revealed by small-game use; and (3) increased efficiency in food capture, processing, and energy retention through technology, and the eventual expansion of technology into social (symbolic) realms of behavior. Niche boundary shifts, examined here in eight dimensions, tend to cluster at 500 thousand years ago (KYA), at 250 KYA, and several in rapid succession between 50 and 10 KYA. Most of these shifts appear to be consequences of competitive interaction, because high-quality, protein-rich resources were involved. Many of the boundary shifts precede major radiations in the equipment devoted to animal exploitation. With a decline in trophic level after 45 KYA, demographic increase irreversibly altered the conditions of natural selection on human societies, from a largely interspecific competitive forum to one increasingly defined by intraspecific pressures. Regionalization of Upper Paleolithic artifact styles is among the many symptoms of this process.  相似文献

The paper presents an alternative to scholarship on the distributional politics of finance that emphasizes citizenship‐based claims to new financial rights. To compensate for the dominance of exclusion‐based etiologies of financial marginality in financial geography, I reframe financial exclusion as a problem of financial government—that is, as a problem of conducting the conduct of risky populations without threatening the security and autonomy of financial markets. Drawing on Foucault's distinction between technologies of discipline and security, I describe how barriers to the extension of financial government create tiered processes of financial subject formation. The inchoate “subprime’ financial subject produced is the correlate of a specialized financial governmentality—a homo subprimicus eminently governable by financial means. I close by calling for greater attention to questions regarding the relationship between technologies for valorizing bare life, new systems of financially mediated value extraction, and emerging capitalist class processes.  相似文献

Abstract: The “mobility turn” claims that conceding analytical priority to the study of mobility is the best way to overcome methodological approaches based on fixed and stable categories argued to be unviable in a world that is increasingly mobile. In this paper I argue that the mobility approach, far from reaching this goal, in fact reifies the cleavage between mobility and immobility, relegating immobility to a passive, undertheorized position, and collapsing the complex workings of power, thus foreclosing a dialectical understanding of the contradictory albeit co‐produced processes of mobilization and immobilization. Drawing on an ethnographic analysis of the impacts of changing patterns of accumulation of the tourist industry on the urban space of Palma (Majorca, Spain), I suggest a relational approach attentive to the dialectics of mobility and stability, continuity and change.  相似文献

Pleistocene water crossings, long thought to be an innovation of Homo sapiens, may extend beyond our species to encompass Middle and Early Pleistocene Homo. However, it remains unclear how water crossings differed among hominin populations, the extent to which Homo sapiens are uniquely flexible in these adaptive behaviors, and how the tempo and scale of water crossings played out in different regions. I apply the adaptive flexibility hypothesis, derived from cognitive ecology, to model the global data and address these questions. Water-crossing behaviors appear to have emerged among different regional hominin populations in similar ecologies, initially representing nonstrategic range expansion. However, an increasing readiness to form connections with novel environments allowed some H. sapiens populations to eventually push water crossings to new extremes, moving out of sight of land, making return crossings to maintain social ties and build viable founder populations, and dramatically shifting subsistence and lithic provisioning strategies to meet the challenges of variable ecological settings.

Fifty years ago, an ethnographic expedition found primitive human fossils at Lake Eyasi, Tanzania. Subsequent emphasis has centered almost exclusively on cranial morphology, neglecting the discovery site and associated finds. Fauna has been deemed “essentially modern” and racemization dates suggest a late Pleistocene age for the hominid remains; these assessments have been advanced as consistent with a “terminal Middle Stone Age” antiquity. Based on recent observations at the site and new sediment analyses, a provisional sequence is now proposed: an earlier formation, the Eyasi Beds, is distinguished from later Pleistocene deposits, the Mumba Beds, the latter being partially calibrated by uranium series and radiocarbon dates. This evidence indicates that the Eyasi Beds, the probable source of the human fossils, are older than 130,000 years, and the fauna may include seven extinct large mammal species. Documented Eyasi Beds artifacts are mostly unspecialized Middle Stone Age types; no typological or technical features suggest later MSA specializations or innovations foreshadowing Later Stone Age industries. A series of core tools from the lakeshore suggests an industry of Sangoan aspect. All lines of evidence from the locality contradict the young amino acid racemization dates; artifacts and fauna, including archaic Homo sapiens remains, are of probable Middle Pleistocene age.  相似文献

This essay looks at the role that Anglo‐American women played in governing their Irish immigrant domestic servants and at the racial and gendered meanings that were attached to servitude. In the second half of the nineteenth century, female Irish Catholic immigrants predominated in domestic service employment in the north‐eastern United States. Newspaper and magazine articles portrayed the home as a site of conflict where Protestant, middle‐class families clashed with Irish Catholic ‘peasant’ girls newly arrived in the US. Employers depicted ‘Bridget’ or ‘Biddy’, the collective nickname given to Irish domestic servants, as insubordinate, unrefined and prone to violent outbursts. While reliant on domestic service for wages, female Irish immigrants understood that service represented racialised labour in the United States and was viewed as an occupation befitting non‐white populations.  相似文献
