With the deployment of airborne laser sensors as well as more traditional excavation techniques, archeologists have discovered evidence of a massive and sophisticated lost city in the dense Amazon rain forest region of eastern Ecuador in the Andes foothills. Lead researcher Stephen Rostain of the National Center for Scientific Research in France told the BBC, “This is older than any other site we know in the Amazon. We have a Eurocentric view of civilization, but this shows we have to change our idea about what is culture and civilization.” According to the survey of about 200 miles in the Amazon,...

Antoine Dorison, Stéphen Rostain via AP ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ A study based on over 20 years of research into an ancient site in the Amazon rainforest has revealed evidence it was once a large-scale hub of interconnected cities that date back more than 2,500 years. The findings were published Thursday in the journal Science and detail the researchers’ work in mapping the network of settlements, which may be the earliest...

Perched in a helicopter some 650 feet up, scientists used light-based remote sensing technology (lidar) to digitally deforest the canopy and identify the ancient ruins of a vast urban settlement around Llanos de Mojos in the Bolivian Amazon that was abandoned some 600 years ago. The new images reveal, in detail, a stronghold of the socially complex Casarabe Culture (500-1400 C.E.) with urban centers boasting monumental platform and pyramid architecture. Raised causeways connected a constellation of suburban-like settlements, which stretched for miles across a landscape that was shaped by a massive water control and distribution system with reservoirs and canals....

'First Americans were Australian' This is the face of the first known American, Lucia The first Americans were descended from Australian aborigines, according to evidence in a new BBC documentary. The skulls suggest faces like those of Australian aborigines The programme, Ancient Voices, shows that the dimensions of prehistoric skulls found in Brazil match those of the aboriginal peoples of Australia and Melanesia. Other evidence suggests that these first Americans were later massacred by invaders from Asia. Until now, native Americans were believed to have descended from Asian ancestors who arrived over a land bridge between Siberia and Alaska and...

Ancient hearth tests carbon dating Bob Beale ABC Science Online Monday, 17 November 2003 Rock art at Serra da Capivara National Park, home of the Pedra Furada site in Brazil (Embassy of Brazil, London) People were keeping warm by a fire in a rock shelter at least 56,000 years ago, according to new analysis of what may be the oldest known human record in the Americas. This is about 40,000 years earlier than generally agreed for when people first arrived in the Americas. The international team of researchers dated charcoal from a hearth at the controversial Pedra Furada archaeological site...

Genetic analysis of plant species has long pointed to the lowlands of southwest Amazonia as a key region in the early history of plant domestication in the Americas, but systematic archaeological evidence to support this has been rare. The new evidence comes from recently-exposed layers of the Teotonio archaeological site, which has been described by researchers as a "microcosm of human occupation of the Upper Madeira [River]" because it preserves a nearly continuous record of human cultures going back approximately 9,000 years. In this study, Watling and colleagues analyzed the remains of seeds, phytoliths, and other plant materials in the...

...Anabel Ford, an archaeologist at UC Santa Barbara and director of the university's MesoAmerican Research Center, suggests... that the forest gardens cultivated by the Maya demonstrate their great appreciation for the environment. Her findings are published in the current issue of the Journal of Ethnobiology in an article titled "Origins of the Maya Forest Garden: Maya Resource Management." ...The ancient Maya, who farmed without draft animals or plows, and had access only to stone tools and fire, followed what Ford calls the "milpa cycle." It is an ancient land use system by which a closed canopy forest is transformed into...

Credit: NASA The Amazon River has been around for 11 million years ago and in its shape for the last 2.4 million years ago, according to a study on two boreholes drilled in proximity of the mouth of the Amazon River by Petrobras, the national oil company of Brazil. Until recently the Amazon Fan, a sediment column of around 10 kilometres in thickness, proved a hard nut to crack, and scientific drilling expeditions such as Ocean Drilling Program could only reach a fraction of it. Recent exploration efforts by Petrobras lifted...

The unifying feature behind all of these characteristics is a cultural restriction against talking about things that extend beyond personal experience. This restriction counters claims of linguists, such as Noam Chomsky, that grammar is genetically driven system with universal features. Despite the absence of these allegedly universal features, the Pirahã communicate effectively with one another and coordinate simple tasks. Moreover, Piraha suggests that it is not always possible to translate from one language to another.

REMANSO TALISMA, Brazil — The death of a myth begins with stinging eyes and heaving chests here on the edge of the Amazon rain forest. Every year, fire envelops the jungle, throwing up inky billows of smoke that blot out the sun. Animals flee. Residents for miles around cry and wheeze, while the weak and unlucky develop serious respiratory problems. When the burning season strikes, life and health in the Amazon falter, and color drains out of the riotous green landscape as great swaths of majestic trees, creeping vines, delicate bromeliads and hardy ferns are reduced to blackened stubble. But...

Saving the Selva Maya Sunday, June 29, 2003, By JIM WRIGHT Editor's note: As part of his research for a book, Editorial Writer Jim Wright made several recent trips to the tropical forest in Belize, where until a few weeks ago a smoky haze often clouded the skies. WHAT IS THE SELVA MAYA?The Selva Maya consists of mostly contiguous jungle in three Central American nations: Guatemala, Mexico, and Belize. The three nations have created biosphere reserves, national parks, and other conservation areas to protect the jungle, conduct scientific research, and seek sustainable development. Guatemala has the 5-million-acre Maya Biosphere Reserve.Mexico's...

Forget small nomadic tribes and pristine jungle: the southern Amazon was likely covered in a network of large villages and ceremonial centers before Columbus. Geoglyphs in the southern Amazon are evidence of a once-thriving population. Photograph courtesy of University of Exeter ------------------------------------------------------------------------------------------------------------------------ Before Spanish invaders conquered South America, sparse groups of nomadic people clustered around the Amazon River, leaving the surrounding rain forest pristine and untouched. Or did they? New research suggests a very different story—an Amazonian region peppered with rain forest villages, ceremonial earthworks, and a much larger population than previously thought. The research, funded in part by the...

Parts of the Amazon previously thought to have been uninhabited were home to thriving populations of up to a million people from as early as 1250 AD, research shows. Archaeologists have uncovered evidence there were up to 1,500 fortified villages in the rainforest away from major rivers - two-thirds of which are yet to be discovered. By analysing charcoal remains and excavated pottery, researchers found a 1,100-mile (1,800km) stretch of southern Amazonia that was continuously occupied from 1250 until 1500 AD. People had assumed ancient communities had preferred to live near these waterways, but the new evidence shows this was...

Contact: Dr. Dolores Pipernopipernod@tivoli.si.edu 011-507-212-8101Smithsonian Institution An origin of new world agriculture in coastal Ecuador New archaeological evidence points to an independent origin of agriculture in coastal Ecuador 10,000 to 12,000 years ago. Suddenly, the remains of larger squash plants appear in the record. The Las Vegas site, described by Dolores Piperno of the Smithsonian Tropical Research Institute (STRI) and Karen Stothert, University of Texas at Austin in the February 14th issue of Science, may predate plant domestication sites in the Mesoamerican highlands. The fertile and amazingly diverse lowland tropics seem like a likely place for agriculture to develop. But...

It is often held aloft by environmental campaign groups as an example of one of the last remaining regions of unspoiled habitat left in the world. But instead of being a pristine rainforest untouched by human hands, the Amazon appears to have been profoundly shaped by mankind. An international team of researchers have published evidence that suggests the Amazon was once home to millions of people who lived and farmed in the area now covered by trees.

Previously unknown archeological sites in forest islands reveal human presence in the western Amazon as early as 10,000 years ago, according to research published August 28 in the open access journal PLOS ONE by Umberto Lombardo from the University of Bern, Switzerland and colleagues from other institutions. The study focuses on a region in the Bolivian Amazon thought to be rarely occupied by pre-agricultural communities due to unfavorable environmental conditions. Hundreds of 'forest islands'- small forested mounds of earth- are found throughout the region, their origins attributed to termites, erosion or ancient human activity. In this study, the authors report...

To the untrained eye, all evidence here in the heart of the Amazon signals virgin forest, untouched by man for time immemorial - from the ubiquitous fruit palms to the cry of howler monkeys, from the air thick with mosquitoes to the unruly tangle of jungle vines. Archaeologists, many of them Americans, say the opposite is true: This patch of forest, and many others across the Amazon, was instead home to an advanced, even spectacular civilization that managed the forest and enriched infertile soil to feed thousands. The findings are discrediting a once-bedrock theory of archaeology that long held that...

Many botanists did not see any connection between maize and other living plants. Some concluded that the crop plant arose through the domestication by early agriculturalists of a wild maize that was now extinct, or at least undiscovered. However, a few scientists working during the first part of the 20th century uncovered evidence that they believed linked maize to what, at first glance, would seem to be a very unlikely parent, a Mexican grass called teosinte... George W. Beadle, while a graduate student at Cornell University in the early 1930s, found that maize and teosinte had very similar chromosomes....

Centuries-old European explorers' tales of lost cities in the Amazon have long been dismissed by scholars, in part because the region is too infertile to feed a sprawling civilization. But new discoveries support the idea of an ancient Amazonian urban network—and ingeniously engineered soil may have made it all possible.

One way to keep carbon dioxide out of the atmosphere is to put it back in the ground. In the first of two News Features on carbon sequestration, Quirin Schiermeier asked when the world's coal-fired power plants will start storing away their carbon. In the second, Emma Marris joins the enthusiasts who think that enriching Earth's soils with charcoal can help avert global warming, reduce the need for fertilizers, and greatly increase the size of turnips.
