Summary

Descripción general del contenido del recurso.

This chapter focuses on how human colonization of Sierras of Cordoba (Argentina) impact on the high-ranked prey resource density –i.e. Lama guanicoe-. Three hypothetical scenarios were modelled altering the encounter rate of L. guanicoe and predicting how its variation should broaden or narrow the optimal diet of human societies. Diachronic trends in the Lama sp. encounter rate were analyzed with two quantitative indeces that compare its relative abundance in the assemblages: the “camelid index” and the “artiodactyls index”. The archaeofaunal record reflects the temporal decrease in Lama sp. frequency through the Holocene. This taxonomical trend is associated to a decrease in their encounter rate as a result of human over-explotation under specific ecological conditions. The results draw to the conclusion that a broad-spectrum diet which may not be an exclusively Late Holocene phenomenon and its origins may be found in earlier processes beginning during the Middle Holocene. Thus, the incorporation of small-scale agriculture around ca. 1200-1000 BP cannot be satisfactorily explained only by external factors such as climate changes, the diffusion and/or arrival of new biological populations. Research should consider that past human cultural activities played a dynamic role in this process through niche construction, co-directing subsequent cultural changes that are seen in the archaeological record. Este capítulo se focaliza en como la colonización humana de las Sierras de Córdoba (Argentina) impactó sobre la densidad del recurso del mayor ranking –i.e. Lama guanicoe-. Se plantean 3 escenarios hipotéticos alterando la frecuencia de encuentro con L. guanicoe y prediciendo como su variación va a ampliar o estrechar la dieta óptima de las sociedades humanas. Las tendencias diacrónicas en las frecuencias de encuentro con L. guanicoe se analizaron con 2 índices cuantitativos que comparan su abundancia relativa en los conjuntos: el “índice de camélidos” y el “índice de artiodáctilos”. El registro arqueofaunístico refleja una caída en la frecuencia de Lama sp. a través del Holoceno. Este patrón es asociado a una reducción en la tasa de encuentro como resultado de la sobreexplotación humana bajo condiciones ecológicas específicas. Los resultados indican que una dieta de amplio espectro no es un fenómeno exclusivamente del Holoceno Tardío y sus orígenes deben buscarse tempranamente en el Holoceno Medio. En consecuencia, la incorporación de prácticas agrícolas a pequeña escala ca. 1200-1000 AP no puede ser explicada satisfactoriamente por factores externos, como cambios climáticos, Fil: Rivero, Diego Eduardo.
