The chronology of the Inca Empire has traditionally relied on ethnohistoric dates, which suggest that a northern expansion into modern Ecuador began in AD 1463 and a southern expansion into modern Argentina began in AD 1471. We test the validity of these dates with two Bayesian models, which show that the ethnohistoric dates are incorrect and that the southern expansion began before the northern one. The first model of seven dates shows that the site of Chamical, Ecuador, was first occupied cal AD 1410–1480 (95% probability) and has a high probability of being built prior to the ethnohistoric date. The second is an outlier model of 26 14C dates and 19 thermoluminescence (TL) dates from 10 sites along the empire’s southeastern limit in northwestern Mendoza, Argentina. Here, the Inca occupation began cal AD 1350–1440 (95% probability), also earlier than the ethnohistoric date. The model also suggests that the Inca occupation of Mendoza lasted 70–230 yr (95% probability), longer than previously thought, which calls for new perspectives on the timing and nature of Inca conquests and relationships with local groups. Based on these results, we argue it is time to abandon the traditional chronology in favor of Inca chronologies based on Bayesian models.

“…Because demography is strongly linked to socio-cultural complexity (Henrich, 2004;Powell et al, 2009;Turchin et al, 2018) and energy consumption/ production (Freeman et al, 2018a(Freeman et al, , 2018b, representing therefore one of the most important factors behind the impacts of human activities on the landscape (Ellis et al, 2013;Malm and Hornborg, 2014), we reconstructed paleodemographic history at micro-regional scales over the last three millennia. Particularly, we estimated summed probability distributions (SPDs) of radiocarbon and thermoluminescence dates from published archaeological sites from the northern (Gayo et al, 2015;Troncoso and Pavlovic, 2013) and central (Campbell and Quiroz, 2015;Falabella et al, 2015Falabella et al, , 2007Sanchez, 2001, Sanhueza et al, 2006, 2003Troncoso and Pavlovic, 2013) regions (see Text S1 in Supplemental Material 1, Datasets 1-2 in Supplemental Data 1). This method uses "dates as data" and assumes that changes in the accumulation of chronological determinations on archaeological remains reflect variations in the intensity of human activities through time as a proxy of population levels (Chaput and Gajewski, 2016;Rick, 1987).…”

Elementa: Science of the Anthropocene

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 biophysical systems as socio-cultural complexity and pressures on natural resources increased over the last three millennia. We demonstrate that Pre-Columbian societies intentionally transformed Chile’s northern and central regions by continuously adjusting socio-cultural practices and/or incorporating technologies that guaranteed resource access and social wealth. The fact that past human activities led to cumulative impacts on diverse biophysical processes, not only contradicts the notion of pristine pre-Industrial Revolution landscapes, but suggests that the Anthropocene derives from long-term processes that have operated uninterruptedly since Pre-Columbian times. Moreover, our synthesis suggests that most of present-day symptoms that describe the Anthropocene are rooted in pre-Columbian processes that scaled up in intensity over the last 3000 years, accelerating after the Spanish colonization and, more intensely, in recent decades. The most striking trend is the observed coevolution between the intensity of metallurgy and heavy-metal anthropogenic emissions. This entails that the Anthropocene cannot be viewed as a universal imprint of human actions that has arisen as an exclusive consequence of modern industrial societies. In the Chilean case, this phenomenon is intrinsically tied to historically and geographically diverse configurations in society-environment feedback relationships. Taken collectively with other case studies, the patterns revealed here could contribute to the discussion about how the Anthropocene is defined globally, in terms of chronology, stratigraphic markers and attributes. Furthermore, this deep-time narrative can potentially become a science-based instrument to shape better-informed discourses about the socio-environmental history in Chile. More importantly, however, this research provides crucial “baselines” to delineate safe operating spaces for future socio-ecological systems.

“…La zona de Chile Central cuenta con el número más elevado de fechados tempranos (Falabella et al 2015;Sanhueza et al 2003;Sanhueza y Falabella 2000;Vasquéz et al 1999). Existen 31 fechados de 15 sitios, cinco de los cuales se ubican en la costa (Curaumilla 1 y 2, Laguna El Peral-C, Arévalo y Arévalo 2).…”

“…Problemas similares y adicionales surgen con el uso de las sumas de probabilidades de fechados, que son simples de elaborar y cada vez más comunes en la arqueología y también en los Andes del sur (p. ej., Barberena et al 2016;Cornejo 2014;Falabella et al 2015;Gil et al 2015;Méndez et al 2015). Sin embargo, no todas esas interpretaciones recientes hacen una consideración adecuada de las limitaciones del método (Bamforth y Grund 2012; Bayliss et al 2007:9-11;Contreras y Meadows 2014;Williams 2012).…”
