Human nature is a puzzling matter that must be analysed through a holistic lens. In this essay, I foray into anthropology's biosocial dimensions to underscore that human relations span from microorganisms to global systems. I argue that the future of social-cultural anthropology depends on the integration of evolutionary theory for its advancement. Ultimately, since the likelihood of novel zoonoses' emergence, digital ethnography could offer remarkable opportunities for ethical and responsible inquiries.

Through an ethnographic and ethnobotanical investigation of Amazonian Shuar gardening practices, I aim to (1) unravel the basic and more complex relationships exhibited by Shuar gardening activities, which involve humans, tubers, and mythical originators and mediators of ecological and biological processes; (2) compare Shuar horticultural practices with those of other Indigenous tropical horticulturalists; and (3) unveil how and to what extent concepts of plant agency shape traditional cultivation systems. My study reveals that the rapid growth and high yield of tubers significantly depend on women’s sophisticated cognitive skills, manifested through specific nurturing methods for cultivated plants and gardening rituals to engage with cosmic and mythical forces. Beyond the embodied practices of tending tubers and the ritual behaviors displayed by women, the agential qualities of plants play a crucial role in shaping the ritual and mytho-cosmological structure underlying gardening activities. Ultimately, biosocial, mythical, cosmic, and ontological connections between biological kingdoms inform growth patterns, fertility, and reproduction within the garden domain.

This thesis uses a biosocial anthropological approach to explore the wide variety of human-environmental interactions exhibited by the Shuar of the Ecuadorian Amazon. Based on 10 months of ethnographic inquiry and deploying a comparative and evolutionary perspective, this thesis focuses primarily on the holistic nature of ancient subsistence patterns. I delve into the adaptive strategies exhibited by the contemporary Shuar and attempt to delineate the socio-ecological, ritual and cosmological significance of these patterns of behaviour. I suggest how subsistence adaptations, like hunting, which have been greatly diminished in the Shuar communities, nevertheless reveal particular forms of cross-species interactions likely deeply rooted in coevolutionary processes. As clearly indicated by informants' oral histories, hunting patterns and meat-eating behaviour show complex trophic, socio-structural and ritual associations between humans and animal taxa. I then hypothesise that food taboos against eating particular animals (mostly large mammals) may have functioned as mechanisms for the preservation of prey and likely arose from ancient relationships with extinct megafauna. Further, concerning horticulture, a subsistence strategy still practised by the Shuar, I reveal how specific forms of human-plant interactions, such as those with Manihot esculenta Crantz and Guadua spp., inform patterns of patterns of growth, fertility and reproduction. This Amazonian form of human-plant coevolution exhibited by traditional horticulture underscores, in principle, basic and higher-order relational processes exemplified by the biosocial, ritual, ontological, and myth-cosmological associations between organismic kingdoms. Concerning the use of medicinal and psychoactive plants, I show how these kinds of botanical knowledge frequently intersect, thus representing adaptive behaviours highly dependent on embodied and cognitive engagements with plant materials. Both conceived as elementary forms of cure and primary triggers of metaphysical formulations, relationships with these elements of the plant kingdom are likely to be well-embedded in our evolutionary history. Lastly, the thesis' attempt at cross-species comparisons linked to different evolutionary periods (i.e., archaic hominins, extant forager-horticulturalists and non-human primates) may shed new light on the nature of complex adaptive patterns exhibited by Indigenous peoples in general and the Shuar in particular.

Throughout our entire evolutionary history, the physical environment has played a significant role in shaping humans’ subsistence adaptations. As early humans began to colonise novel biomes and construct ecological niches, their behavioural flexibility appeared as an unquestionable fact. During the Late Pleistocene-Holocene transition, the shift from foraging to farming radically altered ecosystem services, resulting in increased exposure to zoonotic pathogens and the emergence of structural inequalities that pervade our current human condition in the Anthropocene epoch. The article seeks to use an anthropological biosocial analysis to explore the diverse evolutionary paths humans have taken, which in turn shape their relationships with the natural world. Given the enigmatic nature of human behavior, it is essential to examine it holistically to understand how different subsistence patterns (e.g., intensive agriculture, foraging, and horticulture) have influenced resilience and adaptation to environmental challenges.

Human nature is a puzzling matter that must be analysed through a holistic lens. In this commentary, I foray into anthropology's biosocial dimensions to underscore that human relations span from microorganisms to global commodities. I argue that the future of social-cultural anthropology depends on the integration of evolutionary theory for its advancement. Ultimately, since the likelihood of novel zoonoses' emergence, digital ethnography could offer remarkable opportunities for ethical and responsible inquiries.

The outbreak of SARS-CoV-2 has threatened ethnographic inquiry, undermining its quintessential characteristic. Participant observation, then, has been thoroughly dismembered by the radical measures implemented to prevent the spread of the virus. This phenomenon, in short, has dragged anthropologists to a liminal state within which ethnography is paradoxically caught in an onto-epistemological unstable vortex. The question of being here and not there, during the pandemic, is epitomised in the instability of different spatio-temporal contexts that overlap through technological mediations. Reflecting on previous fieldwork experiences and current virtual inquiries with the Shuar of the Ecuadorian Amazon unfolds how COVID-19 has thoroughly reshaped how the author approaches subjects' socio-ecological settings. Against this background, the article argues that corporeal immersion remains a necessary condition for the anthropological scrutiny of multispecies relationalities amidst the challenging times of the Anthropocene. The article nevertheless demonstrates that the intellectual efforts to grasp the different material temporalities of virtual spaces embrace the ethical principles concerning the renunciation of fieldwork with vulnerable communities. Furthermore, a reflective and speculative stance is proposed to actualise the snapshots of faraway physicalities linking them to past embodied and multi-sensory experiences. It is ultimately theorised how these mnemonic devices operate as creative forms of inquiry that overcome the pandemic consequences, extra-stimulating our cognitive capabilities to reflect on prior and possible socio-material interactions.

Based on a discussion of the theoretical contributions of Claude Lévi-Strauss and Pierre Clastres, this article explores social relationships as more than a human dimension. Though strongly analysed by both anthropologists, these relationships appear to involve indigenous societies’ whole ecological and cosmological system. In this sense, reciprocity, social cohesion, and exchange can be understood as material and immaterial interrelationships between entities of a more than a corporeal world. I argue, then, that to go beyond the mere anthropocentric conceptualisation of sociality in a nature good to think, we need to holistically conceive the interconnected levels of trophic, socio-structural and socio-cosmic relationships and exchanges between human and non-human beings in the ecosystem.

Al tratar de disolver la neta separación entre una mente racional y la materia inerte abogada por el dualismo Cartesiano, el monismo lucha por reunificar estas distintas realidades ontológicas. Tal como para Claude Lévi-Strauss y Baruch Spinoza, esa dicha unificación no puede prescindir de la trascendencia de la mente humana como locus del pensamiento y conocimiento de la naturaleza externa. A través de una discusión entre las abstracciones de la etnología Amerindia (animismo-perspectivismo), las teorizaciones del estructuralismo y las relaciones que estos tienen con algunas especulaciones filosóficas occidentales, este artículo trata de analizar las intricadas interacciones humano-naturaleza entre los Shuar de la Amazonía Ecuatoriana. De esta forma, se argumenta que las realidades metafísicas de las experiencias oníricas y visionarias están ontológicamente determinadas por el grado de intensidad de contacto que los humanos establecen con las subjetividades materiales del ecosistema.

Cultural landscapes represent a complex category where the nature-culture dichotomy seem to not be able to unfold the main features and the profound relations that humans have with the environment. Drawing on ethnographic data collected in the saltpans of Se-ovlje (Slovene Istria) and Janubio (Lanzarote--Canary Islands) this article examines informant`s perceptions about the awareness of the importance and the enhancement of the holistic values of both saltpans, as well as the impacts and benefits of tourism. Comparing these perceptions about both cultural landscapes, I try to suggest that the complex fruitfully relations between humans and nature in these saltpans are at odds with the neoliberal logic of nature which exploit and commoditize its resources depriving them of their respective agency. A sustainability to contrast the harmful activities of the market ought to be understood not as a simply isolation and fencing of nature for the sake of conservation, but as a preservation that need to foster the continuity of the deep interactions between human culture and non-human nature which are the core of the cultural landscapes.

It is well known the harmful effects that savage capitalism has been causing to the environment since its introduction in a sphere in which a different logic and approach to nature are the essential conditions for the maintenance of the ecosystem and its complex relations between humans and non-human organisms. The amazon rainforest is a portion of the planet in which for thousands of years its human dwellers have been interacting with nature that it is understood beyond its physical condition. Thus, to what extent Amazonian’s approaches to nature could be considered as a moral philosophy through which the way of conceptualizing nature and its non-human denizens enhances the continuity of life and the intimate relations between entities? To answer this question, I will explore the cosmological system of the Shuar of the Ecuadorian Amazon with whom I lived for 5 months between July and November 2018, and thereby elucidate the spiritual relations that this society has with the metaphysical domain of nature.
