an ancient andean civilisation that lasted 4000 years thereabouts was declared the ".. oldest known complex society in the Americas..." after confirmed radio-carbon datings:
The civilisation, which was characterised by stone pyramids, large ceremonial structures and agriculture, spread over three windy valleys in the Norte Chico region of Peru.
i expect the national geographic to explore more of it in-depth in a forthcoming issue.
