Far before the looming pyramids and the learned librarians at Alexandria, Egyptian civilization sprung up from the fertile banks of the Nile. Long predating the Inca empire and the sprawling structures of Macchu Picchu, Andean civilization emerged from a whole bunch of llama poop.
For civilizations to take root, people need to have enough food on hand to put time and energy into activities like waging war, building stuff, and composing epic poetry. In the high and rugged Andes, growing that much maize—the staple crop of ancient South America—isn’t easy. That’s what llama droppings are for, a new study suggests.
In the rainforest along the border between Brazil and Peru, an indigenous tribe is ignoring the 21st century and living life the old-fashioned way. Experts believe this “uncontacted tribe” has had no direct contact with mainstream society, but the Brazilian government has known about the tribe for 20 years and routinely flies above the settlement to check on the inhabitants’ well-being.
NOw, the BBC has released the first ever video footage of this tribe, which had previously only been seen in photographs:
The footage was filmed in cooperation with the Brazilian government, and was featured on the BBC’s Human Planet series. It was shot in the summer of 2010 along the Peru-Brazil border using a zoom lens that allowed the crew to film from more than a half-mile away.
