    '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...

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...
  • Archeological Plant Remains Point to Southwest Amazonia as Crop Domestication Center

    Popular Archaeology ^ | Wednesday, July 25, 2018 | PLoS ONE
    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...

    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...

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...
  • Studies of Amazonian languages challenge linguistic theories

    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...

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...

    Carson and his colleagues wanted to explore the question of whether early Amazonians had a major impact on the forest. They focused on the Amazon of northeastern Bolivia, where they had sediment cores from two lakes nearby major earthworks sites. These sediment cores hold ancient pollen grains and charcoal from long-ago fires, and can hint at the climate and ecosystem that existed when the sediment was laid down as far back as 6,000 years ago. An examination of the two cores — one from the large lake, Laguna Oricore, and one from the smaller lake, Laguna Granja — revealed a...

    Look around the Amazon rainforest today and it’s hard to imagine it filled with people. But in recent decades, archaeologists have started to find evidence that before Columbus’s arrival, the region was dotted with towns and perhaps even cities. The extent of human settlement in the Amazon remains hotly debated, partly because huge swaths of the 6-million-square-kilometer rainforest remain unstudied by archaeologists. Now, researchers have built a model predicting where signs of pre-Columbian agriculture are most likely to be found, a tool they hope will help guide future archaeological work in the region. In many ways, archaeology in the Amazon...

    A series of ancient underwater etchings has been uncovered near the jungle city of Manaus, following a drought in the Brazilian Amazon. The previously submerged images -- engraved on rocks and possibly up to 7,000 years old -- were reportedly discovered by a fisherman after the Rio Negro, a tributary of the Amazon river, fell to its lowest level in more than 100 years last month... Though water levels are now rising again, partly covering the apparently stone age etchings, local researchers photographed them before they began to disappear under the river's dark waters. Archaeologists who have studied the photographs...

    "These data are directly relevant to the resilience of Amazonian conservation, as they do not support the contention that all of Amazonia is a 'built landscape' and therefore a product of past human land use," Bush says. "Most archaeologists are buying into the argument that you had big populations that transformed the landscape en masse. Another group of archaeologists say that transformation was very much limited to river corridors, and if you went away from the river corridors there wasn't that much impact. That's what our findings tend to support." Bush doesn't expect that his new findings will settle the...

    LAHORE: The vast Amazon rainforest is on the verge of being turned into desert, with catastrophic consequences for the world’s climate, alarming research suggests. And the process, which would be irreversible, could begin as early as next year. Geoffrey Lean and Fred Pearce, writing for The Independent on Sunday, quote studies conducted by the blue-chip Woods Hole Research Centre in Amazonia as concluding that the forest cannot withstand more than two consecutive years of drought without breaking down. “Scientists say that this would spread drought into the northern hemisphere, including Britain, and could massively accelerate global warming with incalculable consequences,...

    RIO DE JANEIRO (AFP) - Archaeologists discovered a pre-colonial astrological observatory possibly 2,000 years old in the Amazon basin near French Guiana, said a report. "Only a society with a complex culture could have built such a monument," archaeologist Mariana Petry Cabral, of the Amapa Institute of Scientific and Technological Research (IEPA), told O Globo newspaper. The observatory was built of 127 blocks of granite each three meters (10 feet) high and regularly placed in circles in an open field, she said. Cabral said the site resembles a temple which could have been used as an observatory, because the blocks...
