Discovery of a unique drainage and irrigation system that gave way to the 'Neolithic Revolution' in the Amazon

A pre-Columbian society in the Amazon developed a sophisticated agricultural engineering system that allowed them to produce maize throughout the year, according to a discovery by a team of researchers from the Institute of Environmental Science and Technology (ICTA-UAB) and the Department of Prehistory at the Universitat Autònoma de Barcelona, (Spain); the Universities of Exeter, Nottingham, Oxford, Reading and Southampton (UK); the University of São Paulo (Brazil) and Bolivian collaborators.
