TL;DR: Genomic, linguistic, archaeological, and paleoecological data suggest that the southwestern Amazon was a secondary improvement center for partially domesticated maize, responsible for the diversity and biogeography of modern South American maize.

TL;DR: The working hypothesis is that two very distinct populations entered the New World by the end of the Pleistocene, and that the transition between the cranial morphology of the Paleoindians and the morphology of later Native Americans was abrupt.

TL;DR: In this paper, a synthesis of our present knowledge about the 12,000/8000 BP period, biological aspects of the Lagoa Santa people and their subsistence are discussed. But claims for a very ancient presence of Man before 13,000 BP (Itaborai, Toca da Esperanca, Pedra Furada and Lapa Vermelha sites) are polemic because putative structures and artifacts could have been made by natural processes.

TL;DR: The results obtained clearly confirm the idea that the Americas were first colonized by a generalized Homo sapiens population which inhabited East Asia in the Late Pleistocene, before the definition of the classic Mongoloid morphology.

TL;DR: In this article, eleven burials excavated in Perua?u Valley since 1981 were discussed, and the skeleton position and objects accompaning it were described, with the existence of burial patterns in the two periods (Medium Archaic - 4.500/7.000 BP and Medium/Recent Ceramist - 600/1.200 BP).
