Late Holocene Maize Diversity and Cultural Remains from the Northern Neotropics: The Site of Cueva La Capilla, Venezuelan Andes

Arturo Jaimes, Diego Vargas, Lorena Becerra‐Valdivia, Martina Lari et autres

Abstract In the northern neotropics, given poor preservation of macro-fossils and funding/research biases, our understanding of ancient cultures’ dynamics is limited. Here, we document the botanical and cultural remains at an early ceramic archaeological site, Cueva La Capilla, northeast of the Venezuelan …

Diverse megamammals exploited by humans, chronology and palaeoecology at Taima-Taima, Late Pleistocene, South America

Jorge D. Carrillo-Briceño, Karina Vanesa Chichkoyan, Arturo Jaimes, Lorena Becerra‐Valdivia et autres

The arrival of humans to the Americas at the end of the Pleistocene has been one of the foundations of the hypothesis that hunter-gatherer groups had a direct role in the extinction of megafauna. However, empirical evidence of the exploitation of megafauna …

Westerly wind shifts drove Southern Hemisphere mid-latitude peat growth since the last glacial

Zoë Thomas, Haidee Cadd, CHRIS S. M. TURNEY, Lorena Becerra‐Valdivia et autres

Abstract Extratropical peatlands in the Southern Hemisphere preserve detailed information on climatic and environmental change going back millennia. They are particularly valuable for understanding the evolution of the mid-latitude southern westerly winds (SWW), which play a major role in driving regional temperature …

µCT Scanning Effects on DNA and a Multi-Step Workflow for Archaeological Petrous Bones

Lumila Paula Menéndez, Pierre Luisi, María Clara López‐Sosa, Sergio Monteiro Da Silva et autres

Abstract The petrous portion of the temporal bone is a key element in human evolutionary studies due to its exceptional preservation of biomolecules and morphological information. However, intensive and often redundant sampling has raised concerns about sustainability and long-term conservation. Here we …

Late Quaternary population expansion in gray brocket deer [Subulo gouazoubira (G. Fisher, 1814), Cervidae, Mammalia] in Brazil

Alex Hubbe, Mark Hübbe, Elver Luiz Mayer, Eliane Nunes Chim et autres

ABSTRACT There is little information about the changes in the abundance of mammalian species in South America during the late Quaternary, which is a key parameter to understanding past ecological and evolutionary dynamics. Here, we describe a conspicuous increase in the abundance …

Localised land-use and maize agriculture by the pre-Columbian Casarabe Culture in Lowland Bolivia

Joseph Hirst, Marco Felipe Raczka, Umberto Lombardo, Ezequiel Chavez et autres

Multiple pre-Columbian (pre-1492 CE) archaeological sites now challenge the traditional portrayal of Amazonia as a ‘pristine wilderness’. This is especially true within the forest-savanna mosaic landscapes of lowland Bolivia, where the pre-Columbian Casarabe Culture constructed hundreds of settlement mounds, integrated with a …

Climate influence on the early human occupation of South America during the late Pleistocene

Lorena Becerra‐Valdivia

The settlement of South America marks one of the final steps in human expansion. This study examines the impact of climate change on this process, focusing on two millennial-scale climatic phases-the Antarctic Cold Reversal and Younger Dryas. Using Bayesian chronological modelling, a …
