Inferring past demographic changes at different spatial scales in Northwest Patagonia and central‐south Chile
In this study, we compare the patterns of demographic changes in populations from Northwest Patagonia and central‐south Chile throughout the Late Pleistocene–Holocene obtained from absolute dates with those resulting from molecular genealogies. We have found that temporal distributions of frequencies of absolute dates constitute a more sensitive demographic indicator than molecular data to make inferences at small spatial scales in the region. Mo…
Spatio-temporal demographic dynamics of the human populations from Northwest Patagonia and central Chile during the Pleistocene-Holocene
First analysis of mitochondrial lineages from the eastern Pampa–Patagonia transition during the final late Holocene
OBJECTIVE: Studies on population genetics have become highly relevant for understanding the evolutionary history of human settlement in southern South America. The eastern Pampa-Patagonia transition is an area that stands out due to its complex population dynamics, especially during the last about 1,000 years BP. The aim of this work is to characterize the maternal lineages of individuals buried in the Paso Alsina 1 archaeological site (ca. 500 y…
Hunter-Gatherer Persistence and Demography in Patagonia (Southern South America)
The results of this chapter suggest that hunter-gatherers from northwest and south Patagonia were resilient to the significant ecological changes that took place during the Late Pleistocene and Early Holocene. In particular, the rate of population growth was resistant to reduction in the diversity of available resources as a consequence of megafaunal extinctions around 10 000 BP. The resistance of hunter-gatherers from northwest and south Patagon…
Mitochondrial-DNA Phylogenetic Information and the Reconstruction of Human Population History
Mitochondrial DNA (mtDNA) sequences are becoming increasingly important in the study of human population history. Here, we explore the diffferences in the amount of information of diffferent mtDNA regions and their utility for the reconstruction of South American population history. We analyzed six data sets comprising 259 mtDNA sequences from South America: Complete mtDNA, Coding, Control, hypervariable region I (HVRI), Control plus cytochrome b…
Domestication and human demographic history in South America
OBJECTIVES: The early groups of hunter-gatherers who peopled South America faced significant ecological changes in their trophic niche for a relatively short period after the initial peopling. In particular, the incorporation of cultigens during the Holocene led to a wider trophic niche and probably to an increased carrying capacity of the environment. Here, we study the relationship between the incorporation of domestic resources during the Holo…
Peopling time, spatial occupation and demography of Late Pleistocene–Holocene human population from Patagonia
Linajes Maternos en Muestras Antiguas De La Puna Jujeña. Comparacion Con Estudios De La Region Centro-Sur Andina
Las evidencias arqueológicas proporcionan abundantes pruebas sobre una activa interacción entre poblaciones del sur de Perú, oeste de Bolivia, norte de Chile y noroeste de Argentina. Esa información sumada a los estudios de ADN en individuos prehispánicos proveen evidencia directa sobre la historia biológica y la dinámica de las poblaciones, aportando nuevas perspectivas al entendimiento de la dispersión y variabilidad de los amerindios. El objet…
