Whether humans or climate change caused the extinction of megafaunal populations is actively debated. Caves in the Lagoa Santa provide mixed assemblages of megafauna and human remains; however, it remains uncertain the extent to which humans and mega

Humans have been present in the Andes since about 12,000 calibrated years before present (cal yr BP), transitioning from hunter-gatherers to agropastoralist societies in the mid-Holocene. Yet, the timing and effects of this change in behavior on the

Two paleoecological histories spanning the period of human settlement in southeastern Brazil
Autor: Marco F. Raczka, Mark B. Bush, Crystal N. H. McMichael, Paulo Eduardo de Oliveira
Publikováno v: Journal of Quaternary Science. 28:144-151
The absence of human occupation sites in southeastern Brazil during the mid Holocene has been referred to as the 'Archaic Gap' (8970–1940 cal. a BP) and is predicted to have resulted from increased aridity. A ca. 14 000 cal. a pollen history from t
