Who would've thought deforestation had an upside?

Satellite flyovers of newly cleared land in the Amazon have uncovered a vanished civilization that could rival the Incans or Aztecs in sophistication.

Researchers found mysterious geometric trenches and other earthworks carved into the landscape as early as a decade ago, but satellites have paved the way for the discovery of over 200 giant structures.

Writing in the journal Antiquity, the researchers say the the formations stretch for some 250 kilometers (155 miles) across the upper Amazon basin east of the Andes mountains and appear to be of a similar style throughout, suggesting one vast, united civilization that could have totaled some 60,000 inhabitants.

Researchers also found stone tools, bits of ceramics, and other artifacts buried in mounds along the trenches. So far, the uncovered areas date to between 200 and 1283 A.D., but the team thinks they've seen "no more than a tenth" of the true extent of this archeological wonder. More from an article which appeared Tuesday in the Guardian:

"These revelations are exploding our perceptions of what the Americas really looked liked before the arrival of Christopher Columbus," said David Grann, author of "The Lost City of Z," a book about an attempt in the 1920s to find signs of Amazonian civilizations. "The discoveries are challenging long-held assumptions about the Amazon as a Hobbesian place where only small primitive tribes could ever have existed, and about the limits the environment placed on the rise of early civilisations."

ElDorado2 They are also vindicating, said Grann, Percy Fawcett, the explorer who partly inspired Conan Doyle's book "The Lost World."

Fawcett led an expedition to find the City of Z but the party vanished, bequeathing a mystery.

Many scientists saw the jungle as too harsh to sustain anything but small nomadic tribes. Now it seems the conquistadores who spoke of "cities that glistened in white" were telling the truth.

They, however, probably also introduced the diseases that wiped out the native people, leaving the jungle to claim – and hide – all traces of their civilization.

There is no upside. The planet is unquestionably dying with the Arctic melting, the destruction of coral reefs and the average temperature climbing at rates that demand a complete stop to deforestation releasing CO2.

I strongly recommend that for the preservation of all mankind that we consider methods of conservation quickly.

This was a very extensive civilization and they created a soil that we can not duplicate today. We are trying though.

They did some other interesting stuff apparently with plants.

Take for example the Banana. It has no seeds and the plant produces no seeds. It is propagated solely by root cuttings. Bananas are, by the way, a perfect food. You can subsist on nothing but Bananas and water and not suffer any dietary deficiencies.

Amaranth, the grain of the Incas, is the only grain, so far as I am aware, that has ALL essential amino acids.

I'm sure there are likely others but those are the two I am aware of.

As well is the scale and sophistication of the structures. The largest Pyramid, found outside of Mexico City, is EIGHT miles around at the base. By way of comparison the Pentagram is only 5 miles around.

There are things in the Amazon Basin which no modern man has seen up close and lived. The natives in the area are, based on their legends and such, very protective of them. If you try to visit them they will kill you as it is sacred ground.

Landsat photos of one area in the Amazon jungle spotted a group of Pyramidal "hills" that are identical in form to the Egyptian Pyramids. Click Here for Link to Photos

Dark secret of the soil hints at Amazon kingdoms

High along bluffs overlooking the confluence of the mighty Negro and Solomues rivers, super-sized eggplants, papayas and cassava are flourishing.

Their exuberance defies a long-held belief about the Amazon. For much of the last half-century, archaeologists have viewed the South American rainforest as a "counterfeit paradise" whose inhospitable environment precluded the development of complex societies.

But new research suggests that prehistoric people found ways to overcome the jungle's natural limitations and thrive in large numbers.

The secret, say the theory's proponents, is in the ground under their feet. The fertile soil called terra preta do indio, Portuguese for Indian black earth, was either intentionally created by these pre-Columbian people or is the accidental by-product of their presence.

The research has implications not only for history but for the future of the Amazon rainforest. If scientists could discover how the indigenous populations transformed the soil, farmers could use the technology to maximise the productivity of smaller plots of land, rather than cutting down ever larger swathes of jungle. The benefits of this "gift from the past" are already known to farmers in the area, who plant crops wherever they find terra preta.

"It's made by pre-Columbian Indians and it's still fertile," said Bruno Glaser, a soil chemist from the University of Bayreuth in Germany, who took samples of terra preta recently near the jungle town of Iranduba. "If we knew how to do this it would be a model for agriculture in the whole region."

This specially modified soil is scattered across millions of hectares in the rainforest, in some areas comprising 10 per cent of the ground area. It is typically packed with potsherds and other signs of human habitation.

"We believe there weren't just tribal societies here, but rather, complex chiefdoms, and we're providing the proof," said James Petersen, an archaeologist at the University of Vermont who has spent the past decade working in the Brazilian Amazon.

His team of American and Brazilian archaeologists has excavated more than 60 sites rich in terra preta near the jungle city of Manaus, where the Negro and Solomues rivers merge to form the Amazon River proper.

The archaeologists also cite evidence of giant plazas, bridges, roads and defensive ditches. The earliest signs of large, sedentary populations appear to coincide with the beginnings of terra preta.

"Something happened 2500 years ago, and we don't know what," said a Brazilian archaeologist, Eduardo Neves.

Nice try, pal.

But you are talking about those varieties that mankind has cultured for the world markets. Wild bananas, as all fruits are naturally seed bearing plants.

This was news to me. I had thought the seeds were embedded inside the fruit itself as dark specs.

According to Wiki, those are the seeds but due to cultivation the seeds in the standard banana are no longer fertile. That's not unique to banana's though. Today's corn cannot survive in the wild (I think corn is basically a superbreed version of grass), and modern cultivated strawberries little resemble their tiny wild ancestors.

No doubt there are a number of other examples.

There is a awful lot of untouched land in South America. There's a lot here in Ecuador, which I think is the most densely populated SA country. (Don't quote me on that).

Ever hear of Quinoa?
