The role of plants in the early human settlement of Northwest South America

This paper presents a synthesis on the existing of the role of plants on the adaptive strategies of human groups that settled in Northwest South America since the Pleistocene/Holocene transition. To contextualize the analysis, a brief description of the Colombian Pleistocene sites is presented. The paper presents a broad description of the lithic technology, archaeobotanical record and radiocarbon dates. Plant resources played a key role in the settling of human groups in the forests of the Neotropics. Furthermore, it is suggested that for some areas there is evidence of cultivation as a strategy to increase the carrying capacity of the surrounding environment.
