National Congress of Archaeology, Lima, PER, 08-/08/2017-11/08/2017 recent archaeological works carried out in the Mayo Chinchipe — Marañón basin have demonstrated the existence of a previously unknown antiaculture highlighting the continuous interaction that existed since very early times between the high Amazonia, the Sierra and the Pacific coast. The interaction was deeply rooted in a common cosmology which served as an engine and a means for the social technological development of the peoples, from the archaic to the Formative. The exchange of ideas, knowledge, practices, raw materials and products from different ecological media promoted a solid ideological foundation, which in time characterised the Andean Civilisation. The role played by the villages of the High Amazonia in this process has so far been ignored, or to a lesser extent, due to a lack of research, but the new evidence makes it necessary to rethink many of the theories about the origin and development of civilisation in the Andes.
