Outside this sphere, everything becomes “alien.” In this view of things, which I take to be canonical in the modern West, terrestrial life and biosphere overlap more or less neatly. Yet this idea of an almost perfect convergence is not the only view possible. This study presents two anthropological cases which demonstrate, a contrario, that the modern tendency to envisage the biosphere as “our home environment” or as “our familiar world” is in many ways a historical accident. Other ecumenical possibilities (by which I refer to the ancient Greek notion of the “inhabited world,” the oikumene) are by no means unthinkable. Examining the ecumenical originality of two communities that at first sight seem unrelated – Chachi indigenous people in Ecuador and scientists involved in the search for extraterrestrial life – will allow us to cast new light on the metaphysical underpinnings of the modern biosphere concept.","PeriodicalId":19614,"journal":{"name":"Origins of Life and Evolution of Biospheres","volume":"120 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88754383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reflections on Personhood and Complexity in the Ecological Crisis","authors":"Guido Sprenger","doi":"10.3790/soc.71.1.73","DOIUrl":"https://doi.org/10.3790/soc.71.1.73","url":null,"abstract":"\u0000 The term “animism” is at once a fantasy internal to modernity and a semiotic conduit enabling a serious inquiry into non-modern phenomena that radically call into question the modern distinction of nature and culture. Therefore, I suggest that the labelling of people, practices or ideas as “animist” is a strategic one. I also raise the question if animism can help to solve the modern ecological crisis that allegedly stems from the nature-culture divide. In particular, animism makes it possible to recognize personhood in non-humans, thus creating moral relationships with the non-human world. A number of scholars and activists identify animism as respect for all living beings and as intimate relationships with nature and its spirits. However, this argument still presupposes the fixity of the ontological status of beings as alive or persons. A different view of animism highlights concepts of fluid and unstable persons that emerge from ongoing communicative processes. I argue that the kind of attentiveness that drives fluid personhood may be supportive of a politics of life that sees relationships with non-humans in terms of moral commitment.","PeriodicalId":19614,"journal":{"name":"Origins of Life and Evolution of Biospheres","volume":"61 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84685481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Can the ontological turn help us understand such events? Debates around the ontological turn have hinged around its potential contribution to the analysis of environmental challenges and political conflicts. In this article, I argue that central concepts from the ontological turn – such as animism (Descola 2005) or perspectivism (Viveiros de Castro 2004) – may add nuance but not substance to anthropological understandings of environmental conflicts. I focus on the stakes of these conflicts, the construction of alliances, and the tactics used by the different stakeholders. Taking to heart one of the core premises of the ontological turn, we may think that Western concepts of “nature” and “culture” may hinder our understanding of indigenous Amazonian people’s participation in these conflicts. I argue on the contrary that efforts to overcome these concepts may precisely risk concealing or distorting the actions and statements of indigenous people involved in the conflict.","PeriodicalId":19614,"journal":{"name":"Origins of Life and Evolution of Biospheres","volume":"97 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86010092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The power field associated with Uwí is extensive, and encompasses life and death: on the one hand, Uwí stands at the centre of the ritualization of life, growth, procreativity and abundance; on the other hand, he embodies destructive agency, which has been linked with warfare and its diverse ritual frames. Uwí represents, at the same time, a significant dimension of a Shuar theory of life, as well as a figure within their theory of power, and is closely connected to conviviality and the good life. During the 1960s and 1970s Uwí was adopted and adapted by intercultural Catholic liturgy, and has acquired new ritual elements and new meanings in this context. In recent years, after large gaps between performances from the 1970s to the new millennium, Uwí and his celebration has been merged with the performance of indigeneity as part of intercultural politics in Ecuador. In this framework, the performance of an animistic ontology has been interconnected with the cultural turn in indigenous politics. This contribution explores several questions concerning ontological trajectories, as well as the relationship of ritual and cultural performances to historical developments and political issues.","PeriodicalId":19614,"journal":{"name":"Origins of Life and Evolution of Biospheres","volume":"13 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84813669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Models with 20 amino acids and peptide lengths up to three were considered. It was shown that there are preferred ranges of abundance and similarity parameters where the symmetry breaking can occur in the models with catalytic synthesis / catalytic destruction / both catalytic synthesis and catalytic destruction. It was further shown that models with catalytic synthesis and catalytic destruction statistically result in a substantially higher percentage of the models where the symmetry breaking can occur in comparison to the models with just catalytic synthesis or catalytic destruction.

A wide variety of terrestrial microorganisms, including those counted amongst the most ancient inhabitants of Earth, can cope with high levels of salinity, extreme temperatures, desiccation and high levels of radiation. Key among these are the haloarchaea, considered particularly relevant for astrobiological studies due to their ability to thrive in hypersaline environments. In this study, a novel haloarchaea isolated from Urmia Salt Lake, Iran, Halovarius luteus strain DA50^T, was exposed to varying levels of simulated extraterrestrial conditions and compared to that of the bacteria Bacillus atrophaeus. Bacillus atrophaeus was selected for comparison due to its well-described resistance to extreme conditions and its ability to produce strong spore structures. Thin films were produced to investigate viability without the protective influence of cell multi-layers. Late exponential phase cultures of Hvr. luteus and B. atrophaeus were placed in brine and phosphate buffered saline media, respectively. The solutions were allowed to evaporate and cells were encapsulated and exposed to radiation, desiccation and vacuum conditions, and their post-exposure viability was studied by the Most Probable Number method. The protein profile using High Performance Liquid Chromatography and Matrix Assisted Laser Desorption/Ionization bench top reflector time-of-flight are explored after vacuum and UV-radiation exposure. Results showed that the change in viability of the spore-forming bacteria B. atrophaeus was only minor whereas Hvr. luteus demonstrated a range of viability under different conditions. At the peak radiation flux of 10⁵ J/m² under nitrogen flow and after two weeks of desiccation, Hvr. luteus demonstrated the greatest decrease in viability.

Any living organism may be regarded as a part of a dissipative process that connects irreversible energy consumption with growth, reproduction, and evolution. Under energy-fuelled, far-from-equilibrium conditions, chemical systems capable of exponential growth can manifest a specific form of stability- dynamic kinetic stability (DKS) - indicating the persistence of self-reproducible entities. This kinetic behavior is associated with thermodynamic conditions far from equilibrium leading to an evolutionary view of the origin of life in which increasing entities have to be associated with the dissipation of free energy. This review aims to reformulate Darwinian theory in physicochemical terms so that it can handle both animate and inanimate systems, thus helping to overcome this theoretical divide. The expanded formulation is based on the principle of dynamic kinetic stability and evidence from the emerging field of systems chemistry. Although the classic Darwinian theory is useful for understanding the origins and evolution of species, it is not meant to primarily build an explicit framework for predicting potential evolution routes. Throughout the last century, the inherently systemic and dynamic nature of the biological systems has been brought to the attention of researchers. During the last decades, \"systems\" approaches to biology and genome evolution are gaining ever greater significance providing the possibility of a deeper interpretation of the basic concepts of life. Further progress of this approach depends on crossing disciplinary boundaries and complex simulations of biological systems.
