TL;DR: In this article, a chronology of changes in lake level over the past 120 k.y.t. is presented, and the authors suggest that paleolakes on the Bolivian Altiplano expanded in response to increased moisture in the Amazon and enhanced transport of that moisture onto the altiplano by strengthened trade winds or southward displacement of the Intertropical Convergence Zone (ITCZ).

TL;DR: These age results demonstrate that a morphologically primitive hominin, Homo naledi, survived into the later parts of the Pleistocene in Africa, and indicate a much younger age for the Homo nalingi fossils than have previously been hypothesized based on their morphology.

TL;DR: In this article, the authors focus on the dating and sedimentology of Boodie Cave to establish the framework for ongoing analysis of cultural materials and present new data on these cultural assemblages, including charcoal, faunal remains and lithics.

TL;DR: In this paper, the authors developed several paleoenvironmental records from a broad geographic region spanning the Altiplano in Bolivia (18°S−22°S) and continuing south along the western Andean flank to ca. 26°S.

TL;DR: In this paper, a lake history from the Southern Bolivian Altiplano was used to evaluate precipitation variability over the last 130 ka, showing a strong link between central Andean climate and Atlantic sea surface temperature gradients during the late Pleistocene, even though today rainfall variability is driven mostly by Pacific sea-surface temperature anomalies associated with El Nino/Southern Oscillation.
