La investigación paleoetnobotánica está permitiendo documentar detalles cada vez más específicos acerca de la interacción entre sociedades humanas y su medio ambiente en el pasado. En el caso del desierto de Atacama en el norte de Chile, todas las plantas cultivadas, sin excepción, fueron introducidas de otras regiones donde fueron inicialmente dom...

Introducción y Objetivos: En el desierto de Atacama ciertas plantas viven aisladas y acotadas a regiones con disponibilidad de agua. La conectividad dentro y entre poblaciones depende de las barreras impuestas por el paisaje y de su capacidad de dispersión. Prosopis flexuosa es una especie con alta importancia económica y ecológica incluida en el P...

In deserts, water has been singled out as the most important factor for choosing where to settle, but trees were likely an important part of the landscape for hunter-gatherers beyond merely constituting an economic resource. Yet, this critical aspect has not been considered archaeologically. Here, we present the results of mapping and radiocarbon d...

Different Andean societies underwent processes of expansion and collapse during propitious or adverse climate conditions, resource boost or depletion along with population variations. Previous studies have emphasized that demographic collapses of polities in the Central Andes Area were triggered by warfare and the negative impacts of fluctuating cl...

The overall trajectory for the human–environment interaction has been punctuated by demographic boom-and-bust cycles, phases of growth/overshooting as well as of expansion/contraction in productivity. Although this pattern has been explained in terms of an interplay between population growth, social upscaling, ecosystem engineering and climate vari...

In this study, we examine the long-term trajectory of violence in societies that inhabited the coast of the Atacama Desert in northern Chile using three lines of evidence: bioarchaeology, geoarchaeology and socio-cultural contexts (rock art, weapons, and settlement patterns). These millennia-old populations adopted a way of life, which they maintai...

Textilization processes envisioned as technological transformation of animal fibres and the incorporation of textiles into human bodies, is analyzed among Chinchorro hunter gatherers, along the hyperarid Pacific coast of the Atacama Desert throughout the Holocene (ca. 7800–3500 cal BP). The Chinchorro, as producers and consumers of South American c...

Fossil records of canids are rare and incomplete in South America. In Chile, all well-identified taxa are part of the “South American Canid Clade” and come from sites located in southern Patagonia. Here, we report the first record for Chile of a taxon of the “Canis clade,” assigned to cf. Aenocyon dirus. The fossil remains consist of a partially co...

Standardized Inka tunics, or unku, were created under the auspices of the state as symbolic expressions of its expansionist power. To ensure these textiles acquired the status of effective insignias of power and territorial control, the Inka established and imposed technical and stylistic canons for their production (techne) by means of highly-skil...

South America is a megadiverse continent that witnessed the domestication, translocation and cultivation of various plant species from seemingly contrasting ecosystems. It was the recipient and supplier of crops brought to and from Mesoamerica (such as maize and cacao, respectively), and Polynesia to where the key staple crop sweet potato was expor...

During the Formative period by the Late-Holocene (ca. 3000–1500 BP), semi-sedentary and sedentary human occupations had emerged in the oases, salares, and riverine systems in the central depression (2400–1000 masl) of the Atacama Desert, northern Chile (19–25°S). This hyperarid core was marginally occupied during the post-Pleistocene and middle Hol...

This paper analyses the importance of the South Central Andean High Puna megapatch, above 4000 masl, in the history of late Pleistocene exploration and colonization of the Atacama Desert, including the contrasting habitats that exist towards the hyperarid Pacific Ocean coast or the ecosystems bordering the tropical forests, on the western and easte...

This paper discusses the results of statistical analyses of the domestic ceramic assemblage from the Caleta Vitor Archaeological Complex, northern Chile, a collection that spans 2500 years. Mineralogical analyses were also conducted on a selection of the ceramic sherds using X-ray diffraction (XRD) as well as paste and petrographic analyses. The re...

Funerary art has the body as its main material component, expresses responses to death and offers insight into relationships between the living and the dead. Chinchorro hunter-gatherer-fisher societies along the Atacama Desert coast provide a key example of such connections, having developed one of the world's oldest-known systems of post-mortem bo...

Late Quaternary precipitation dynamics in the central Andes have been linked to both high- and low-latitude atmospheric teleconnections. We use present-day relationships between fecal pellet diameters from ashy chinchilla rats (Abrocoma cinerea) and mean annual rainfall to reconstruct the timing and magnitude of pluvials (wet episodes) spanning the...

The Neolithic or Formative Period in the New World drastically transformed the mode of production in human societies with the domestication of plants and animals. It impacted the way of life and social relations among individuals in permanent farming villages. Moreover, the emergence of elites and social inequality fostered interpersonal and inter-...

Significance The brightly colored feathers of macaws, amazons, and other neotropical parrots were one of the most important symbols of wealth, power, and sacredness in the pre-Columbian Americas. Andean highland and coastal societies imported these exotic goods from Amazonian tropical forests by little-understood mechanisms of exchange. The study o...

South America is well known for its abundance of Quaternary fossiliferous deposits, but well-preserved fossil remains from well-dated sites are scarce in the Atacama Desert and adjacent arid Andes. Here we report on a partially complete skeleton (46%) of a single young (ca. 3–4 years old) extinct horse discovered in the Salar de Surire, a salt flat...

Throughout Earth’s most extreme environments, such as the Kalahari Desert or the Arctic, hunter–gatherers found ingenious ways to obtain proteins and sugars provided by plants for dietary requirements. In the hyperarid Atacama Desert, wild plant resources are scarce and unevenly distributed due to limited water availability. This study brings toget...

As insignia of power and prestige, Inka unku (tapestry tunics) communicated the strength and extent of Inka sociopolitical hegemony in the Andes. Of the 36 known full-size examples in museum collections, only one, found in Argentina, comes from outside Peru. This article investigates another recently excavated unku found out of context on Chile's n...

Recovery methods and techniques for archaeological sampling can yield major differences in abundance and anatomo-taxonomical representation of animals, affecting past social and ecological reconstruction. Despite being a common organic material in archaeological sites, faunal remains typically exhibit differential preservation of species and skelet...

Abstract In the Atacama Desert from northern Chile (19–24°S), Prosopis (Leguminosae) individuals are restricted to oases that are unevenly distributed and isolated from each other by large stretches of barren landscape constituting an interesting study model as the degree of connectivity between natural populations depends on their dispersal capaci...

The archaeological record shows that large pre-Inca agricultural systems supported settlements for centuries around the ravines and oases of northern Chile’s hyperarid Atacama Desert. This raises questions about how such productivity was achieved and sustained, and its social implications. Using isotopic data of well-preserved ancient plant remains...

Pre-European Plant Consumption and Cultural Changes in the Coastal Lluta Valley, Atacama Desert, Northern Chile (Ca. 5140–390 Cal Yr BP). The introduction of domesticated plants into ancient hunting and gathering economic systems expanded and transformed human societies worldwide during the Holocene. These transformations occurred even in the oases...

As with most living organisms, human populations respond to climatic, environmental, and population pressures by transforming their range and subsistence strategies over space and time. An understanding of human ecology can be gained when the archaeological record is placed within the context of dynamic landscape changes and alterations in natural...

Collapses of food producer societies are recurrent events in prehistory and have triggered a growing concern for identifying the underlying causes of convergences/divergences across cultures around the world. One of the most studied and used as a paradigmatic case is the population collapse of the Rapa Nui society. Here, we test different hypothese...

A distinct feature of many of the earliest archaeological sites (13,000-11,200 cal yr BP) at the core of the Atacama Desert is that they lie at or just below the surface, often encased in desert pavements. In this study, we compare these sites and undisturbed desert pavements to understand archaeological site formation and pavement development and...

There are many unanswered questions about the population history of the Central and South Central Andes, particularly regarding the impact of large-scale societies, such as the Moche, Wari, Tiwanaku, and Inca. We assembled genome-wide data on 89 individuals dating from ∼9,000-500 years ago (BP), with a particular focus on the period of the rise and...

Objectives: This article addresses evidence of violence imbedded in both soft and hard tissues from early populations of hunters, fishermen, and gatherers, known as the Chinchorro culture, who lived between 10,000 and 4,000 cal yr BP, along the coast of the Atacama Desert, one of the driest environments on Earth. Our study is aimed to test two hyp...

En este trabajo se describen las relaciones que las sociedades humanas establecieron con su entorno durante el período Formativo (3000-1000 aP) en la Pampa del Tamarugal, Desierto de Atacama, desde una perspectiva teórico-metodológica que pone el acento en el potencial del registro ecofactual. Éste, al mediar entre lo cultural y lo ambiental, propo...

Chapter 2 reviews ancient maritime communities for the hyperarid coast of northern Chile and southernmost Peru throughout the Holocene, with focus on the mid-Holocene Archaic Period. Two regions represent the exorheic and arheic coasts: Caleta Vitor (9,500 cal BP through the Inca occupation) and Copaco (mostly 7100 to 5200 cal BP), respectively. De...

About 13,000 calendar years ago, the Atacama Desert (18–26°S) was occupied by some of the human groups who had begun to populate South America. The archaeological evidence from six sites located in Pampa del Tamarugal (PdT) it the hyperarid core of the Atacama Desert, including different objects and raw materials, shows a connection with different...

Pastoralism and camelid management are traditionally attributed to the sociopolitical, economic and cosmovision of Andean populations, rather than to lowland hunter gatherer societies, living on the Pacific coast where camelid hunting is considered a marginal activity, and husbandry is a difficult enterprise given the hyper-arid conditions of lowla...

It examines the uses and modes of representation of pre-Columbian cultures and indigenous peoples in a group of archaeological museums in Chile from a critical reading covering from the nineteenth to the twenty-first century. The present of the archaeological museums is observed from the complexity of the relations between the pre-Columbian cultura...

The deep-time dynamics of coupled socio-ecological systems at different spatial scales is viewed as a key framework to understand trends and mechanisms that have led to the Anthropocene. By integrating archeological and paleoenvironmental records, we test the hypothesis that Chilean societies progressively escalated their capacity to shape national...

The Pacific Ocean that flanks the hyperarid Atacama Desert of Northern Chile is one of the richest biomass producers around the world. Thus, it is considered a key factor for the subsistence of prehistoric societies (including mixed-economy groups), that inhabited its coastal ecosystems as well as the neighboring inland areas. This study assesses t...

The social groups that initially inhabited the hyper arid core of the Atacama Desert of northern Chile during the late Pleistocene integrated a wide range of local, regional and supra regional goods and ideas for their social reproduction as suggested by the archaeological evidence contained in several open camps in Pampa del Tamarugal (PdT). Local...

A key concern regarding current and future climate change is the possibility of sustained droughts that can have profound impacts on societies. As such, multiple paleoclimatic proxies are needed to identify megadroughts, the synoptic climatology responsible for these droughts, and their impacts on past and future societies. In the hyperarid Atacama...

The European conquest of the New World produced major socio-environmental reorganization in the Americas, but for many specific regions and ecosystems, we still do not understand how these changes occurred within a broader temporal framework. In this paper, we reconstruct the long-term environmental and vegetation changes experienced by high-altitu...

Desde el poblamiento de América del Sur hace alrededor de 14.500 años o antes, que los primeros habitantes de estas tierras se confrontaron con ambientes extremos. En los Andes Centrales, destaca la híper-aridez del desierto de Atacama junto con la altura extrema del Altiplano Andino. En particular, la zona conocida como el desierto absoluto en el...

Los ecosistemas litorales se encuentran en un delicado equilibrio entre la influencia marina y terrestre, albergan una alta biodiversidad y ejercen un importante control sobre los ciclos y flujos biogeoquímicos entre los continentes y los océanos. Las proyecciones de cambio climático para los próximos 100 años señalan a estos ambientes como altamen...

A partir de un trabajo etnográfico centrado en las memorias territoriales de la comunidad aymara de Mulluri (Región de Arica y Parinacota, Norte de Chile) se propone que el pastoreo, un modo de vida tradicional de origen prehispánico, tiñe fuertemente la percepción del espacio de sus habitantes y la clasificación que elaboran en relación al mundo d...

Camelid caravans have played a key role in the complex systems of interregional social interaction that characterizes Andean history. In the northernmost region of Chile, the most frequent archaeological indicators of these caravan systems are trails and rock art images. Cruces de Molinos (LL-43), a rock art site in the Lluta valley, 1100 masl, 40...

From an ethnographic work focused on the territorial memories of the Aymara community of Mulluri (Region of Arica and Parinacota, Northern Chile) it is proposed that pastoralism, as a traditional way of life of prehispanic origin, strongly col ors the perception and systematic of space and of the world of plants. Interviews and participant observat...

The hyperarid conditions of the Atacama Desert preserve remarkable evidence of ancient human foragers beginning at least 13,000 years ago. Although initially considered a harsh and inhospitable environment, recent interdisciplinary research suggests that the Atacama was originally inhabited by highly mobile hunter-gatherers bearing complex technolo...

"The Tarapacá Declaration" draws attention to the urgent need to change how human societies have been using water in the Atacama Desert, based on a historical trajectory spanning several millennia. The Declaration, an initiative that summarizes the results of the CONICYT/PIA, Anillo project SOC1405, is oriented towards civil society and various pol...

A review of the bioarchaeological collections from the site Morro de Arica in northern Chile allowed the identification of two cases of human polydactyly. Both cases are from the Chinchorro culture, hunters, fishers, and gatherers with a maritime orientation who inhabited the coast of the Atacama Desert (9000-3400 BP). Additionally, the analyses of...

The Altiplano constitutes the most extensive, high-elevation terrain in South America. Most archaeological research on the earliest human occupation of this region in the Bolivian Andes derives from sites such as Viscachani where the emphasis has been on typological comparisons of projectile points, rather than on complete and radiometrically dated...

Primary questions regarding the foraging behaviour of the first hunter–gatherers who colonized the New World are how they found, procured and utilized high‐quality raw materials for manufacturing stone tools. In this paper, we present evidence from the late Pleistocene site of Cueva Bautista in the highlands of south‐western Bolivia, which demonstr...
