Research indicates the existence of a complex ancient civilization in the Amazon. It does not appear to be of Inca origin and predates the arrival of the Spanish and Portuguese. I’ll be curious to see how this develops.

From the article:

Signs of what could be a previously unknown ancient civilisation are emerging from beneath the felled trees of the Amazon. Some 260 giant avenues, ditches and enclosures have been spotted from the air in a region straddling Brazil’s border with Bolivia.

The traditional view is that before the arrival of the Spanish and Portuguese in the 15th century there were no complex societies in the Amazon basin – in contrast to the Andes further west where the Incas built their cities.

While some Inca sites lie just 200 kilometres west of the geoglyphs, no Inca objects have been found at the new sites. Neither do they seem to have anything in common with Peru’s Nasca geoglyphs.
