Ancient temple ruins discovered in Andes pull back curtain on lost society after 1,000 years
Archaeologists have discovered the ruins of an ancient South American temple they say has helped pull back the curtain on the workings of its enigmatic Andean civilization.
Known as the Tiwanaku, the society lived in modern-day Bolivia near the southern shores of Lake Titicaca – the highest navigable lake in the world – before their mysterious disappearance more than 1,000 years ago.
People had first started to live in the region around 10,000 years ago, according to University of California at Berkeley archaeologist Dr. Nicola Sharratt. As many as 20,000 people came to reside in the area. Skilled stoneworkers, the Tiwanaku were widely considered to be a precursor of the Inca empire and one of the earliest examples of civilization in the Andes mountains.
'Their society collapsed sometime around 1,000 CE and was a ruin by the time the Incas conquered the Andes in the 15th century,' José Capriles, an associate professor of anthropology at Penn State University, said in a statement. 'At its peak, it boasted a highly organized societal structure, leaving behind remnants of architectural monuments like pyramids, terraced temples and monoliths, most of which are distributed in sites around Lake Titicaca and, while we know Tiwanaku's control and influence extended much further, scholars debate how much actual control over distant places it had.'
Capriles was the lead author of the international study detailing the findings published this week in the journal Antiquity.
The temple is called 'Palaspata,' which was the native name for the area. Palaspata is located on a hill, approximately 130 miles to the south of the Tiwanaku's established historical site. The area was previously known to indigenous farmers, but had never been explored in depth by researchers.
After noticing a strange plot of land with four sides, they turned to technology to learn more. They snapped and compiled satellite images of the site, and also took pictures using cameras aboard unmanned aerial vehicle flights. Then, they used the photos to construct a three-dimensional approximation of the Palaspata and its surrounding landscape. About the size of a city block, the complex includes 15 quadrangular enclosures arranged around a rectangular inner courtyard.
Its composition, the authors said, suggested that it was used to perform rituals following the solar equinox: a bi-annual moment when the sun is positioned directly above the equator. But, it likely was not solely used for religious purposes.
Much about the Tiwanaku civilization remains unknown, but Palaspata would have been in an advantageous trade spot, according to Capriles. Many people traded and built monuments throughout the mountains. This temple connected three main trade routes, including the highlands, a high-altitude plateau, and the Andean valleys of Cochabamba.
'Most economic and political transactions had to be mediated through divinity, because that would be a common language that would facilitate various individuals cooperating,' he explained.
On the surface of the ruins of Palaspata, the scientists found fragments of 'keru' cups, which were used for drinking a traditional maize beer called 'chicha' during agricultural feasts and celebrations. The maize was cultivated in the Cochabamba valleys.
The researchers had worked with the Bolivian Ministry of Cultures, Decolonization, and Depatriarchalization to export samples of the ruins, which were dated at the Penn State's Institute of Energy and the Environment Radiocarbon Dating Lab.
The city is now working with state and national authorities to help properly protect and preserve the site.
'With more insight into the past of this ancient site, we get a window into how people managed cooperation, and how we can materially see evidence of political and economic control,' Capriles said. 'There's still so much to discover that we don't know about, and that could be hiding in plain sight. It just requires opening your eyes to see what's out there.'

One Fruit May Be Evolving in Reverse
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Wild tomatoes on the Galápagos Islands are rewinding millions of years of evolution, according to a new study. Scientists at the University of California, Riverside found that these tomatoes—descended from South American ancestors likely brought to the Pacific archipelago by birds—are producing a toxic molecular cocktail not seen in millions of years. Biologists described this as a rare and striking case of "reverse evolution." Adam Jozwiak, a molecular biochemist at UC Riverside and lead author of the study, told Newsweek that while "de-evolution" makes for a striking headline, what we're really seeing is evolution taking an unexpected turn, reverting to a state that existed millions of years ago. Could something similar happen in humans? Jozwiak said in theory, yes. A bunch of wild tomatoes growing on a plant. A bunch of wild tomatoes growing on a plant. Irina Khabarova "Humans, like all organisms, are subject to evolutionary forces," Jozwiak explained. "If environmental conditions shifted dramatically over long timescales, it's possible that traits from our distant past could re-emerge, but whether that ever happens is highly uncertain. It's speculative and would take millions of years, if at all." The key players in this evolutionary reversal are alkaloids—chemicals that serve as built-in deterrents against pests. Most cultivated tomatoes produce one type of alkaloid structure, but these Galápagos tomatoes have shifted toward an older chemical form—an evolutionary echo from their distant past and similar to compounds found in eggplant. Researchers pinpointed a single enzyme, known as GAME8, that plays a central role in forming these chemicals. Normally, GAME8 adds a chemical group in a specific three-dimensional shape ('right-handed' or 'left-handed'). Mutations in GAME8 among western island tomatoes altered just a few building blocks (amino acids), flipping the shape back to the ancestral form. The research team confirmed this by inserting the modified enzyme into tobacco plants, which then produced the ancient-style alkaloid. The chemical shift is not random. Eastern islands, which are older and more ecologically diverse, host tomatoes making modern alkaloids. In contrast, the harsher environments on younger, western islands seem to favor the ancestral, eggplant-like chemicals. Researchers believe the older alkaloids may offer better defense under these tougher conditions. Jozwiak told Newsweek that the tomato species studied were wild relatives located in the Galápagos and not included in the human diet, which means there are no direct health implications for humans. "If similar changes occurred in cultivated tomatoes, it might affect how these toxins interact with our digestive system or gut microbiome, but that's purely hypothetical," he said. "For now, this discovery is important for what it tells us about evolution, not for any immediate impact on human health." Do you have a tip on a science story that Newsweek should be covering?

Temple of Civilization That Mysteriously Vanished 1,000 Years Ago Revealed
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A newly uncovered ancient temple in the Bolivian Andes is offering archaeologists rare new insights into the Tiwanaku civilization, a once-powerful society that existed over a thousand years ago and was a precursor to the Inca empire before it mysteriously disappeared. The temple—dubbed Palaspata, after the native name for the area—is located on a hilltop in the municipality of Caracollo, near Tiwanaku's historical UNESCO site by Lake Titicaca. The spot was known to local indigenous farmers, but was never explored in depth by researchers because of its unassuming location. However, the position of the site was actually very strategic, anthropology professor José Capriles of the Pennsylvania State University said in a statement. "Their society collapsed sometime around 1000 CE and was a ruin by the time the Incas conquered the Andes in the 15th century", he said. The anthropologist explained that, at its peak, the Tiwanaku civilization boasted a highly organized societal structure and it had left behind remnants of monuments like pyramids and temples. Capriles added: "While we know Tiwanaku's control and influence extended much further, scholars debate how much actual control over distant places it had."

José Capriles / Penn State During the time of the Tiwanaku civilization, the spot in which the newly discovered ruins were found connected three main trade routes. These included the highlands around Lake Titicaca to the north, the llama-herding plains of the Altiplano to the west and the agriculturally rich valleys of Cochabamba to the east. After noticing an unmapped plot of land in the area, researchers from Penn State University and Bolivian institutions used satellite images and 3D reconstruction techniques to create a detailed rendering of the structure and its topography. They found that Palaspata was approximately the size of a city block, and its layout was aligned to perform rituals following the solar equinox. "Most economic and political transactions had to be mediated through divinity, because that would be a common language that would facilitate various individuals cooperating," Capriles said in the study. According to the mayor of the municipality of Caracollo, Ventura Guarayo, these archaeological findings are significant because they highlight a crucial aspect of the local heritage that had been completely overlooked. "This discovery is vital for our community, and we believe its documentation will be invaluable for promoting tourism and showcasing our region's rich history" he said in a statement, adding that the city is working with state and national authorities to ensure proper protection and preservation of the site. "With more insight into the past of this ancient site, we get a window into how people managed cooperation, and how we can materially see evidence of political and economic control," Capriles added. "There's still so much to discover that we don't know about, and that could be hiding in plain sight. It just requires opening your eyes to see what's out there." While the reason behind the collapse of the Tiwanaku civilization still remains a mystery, archaeologist Luis Miguel Callisaya told the BBC that the most widespread hypothesis is an environmental crisis that led to a prolonged drought. To back this theory, scientists even found the bones of 19 women thought to have been sacrificed to the gods in exchange for rain. However, very little is still known about this ancient civilization, in fact, less than 10 percent of their ruins have to this day been excavated. Do you have a science story to share with Newsweek?
