Further Links: The Lost City of Z

Kuikuro Men

Here are a few links and a video for you to explore, armchair-style, the question of  lost civilizations or organized societies in the Amazon. 

The first is a press release from the University of Florida announcing Michael Heckenberger's paper on his findings which were published in Science magazine.  The second is a National Geographic article which provides some of the illustrations from the academic paper itself.  And last is an interesting article and video about the bioengineering of Amazon Basin soil in ancient times.  This "biochar" indicates that the unusually rich soil there was actually man-made centuries ago and would have supported cultivation, thereby sustaining organized settlements.
