The remains of an ancient ape found in a Bavarian clay pit suggest that humans’ ancestors began standing upright millions of years earlier than previously thought, scientists said Wednesday.An international team of researchers says the fossilized partial skeleton of a male ape that lived almost 12 million years ago in the humid forests of what is now southern Germany bears a striking resemblance to modern human bones. In a paper published by the journal Nature, they concluded that the previously unknown species — named Danuvius guggenmosi — could walk on two legs but also climb like an ape.The findings “raise fundamental questions about our previous understanding of the evolution of the great apes and humans,” said Madelaine Boehme of the University of Tuebingen, Germany, who led the research.The question of when apes evolved bipedal motion has fascinated scientists since Charles Darwin first argued that they were the ancestors of humans. Previous fossil records of apes with an upright gait — found in Crete and Kenya — dated only as far back as 6 million years ago.Boehme, along with researchers from Bulgaria, Germany, Canada and the United States, examined more than 15,000 bones recovered from a trove of archaeological remains known as the Hammerschmiede, or Hammer Smithy, about 70 kilometers (44 miles) west of the Germany city of Munich.Among the remains they were able to piece together were primate fossils belonging to four individuals that lived 11.62 million years ago. The most complete, an adult male, likely stood about 1 meter (3 feet, 4 inches) tall, weighed 31 kilograms (68 pounds) and looked similar to modern-day bonobos, a species of chimpanzee.“It was astonishing for us to realize how similar certain bones are to humans, as opposed to great apes,” Boehme said.Thanks to several well-preserved vertebra, limb, finger and toe bones, the scientists were able to reconstruct how Danuvius moved, concluding that while it would have been able to hang from branches by his arms, it could also straighten its legs to walk upright.“This changes our view of early human evolution, which is that it all happened in Africa,” Boehme told The Associated Press in an interview.Like humans, Danuvius had an S-shaped spine to hold its body upright while standing. Unlike humans, though, it had a powerful, opposable big toe that would have allowed it to grab branches with its foot and safely walk through the treetops.Fred Spoor, a paleontologist at the Natural History Museum in London, called the fossil finds “fantastic” but said they would likely be the subject of much debate, not least because they could challenge many existing ideas about evolution.“I can see that there will be a lot of agonizing and re-analysis of what these fossils mean,” said Spoor, who wasn’t involved in the study. 2833

The Supreme Court declined on Monday to take up a case brought by the Little Sisters of the Poor, a Roman Catholic religious order for women, challenging lower court opinions that blocked the Trump administration's effort to weaken the Affordable Care Act's contraceptive coverage mandate. Several cases are still percolating in the lower courts below and it is likely the issue will find its way back to the Supreme Court.The-CNN-Wire? & ? 2019 Cable News Network, Inc., a Time Warner Company.

The US military has flown an increased number of reconnaissance flights in international airspace off the coast of Venezuela during the last several days to gather classified intelligence about the embattled government of President Nicholas Maduro, according to two US defense officials.The officials would not detail which US military aircraft are being used, but the Navy and Air Force maintain several large fixed-wing aircraft capable of intercepting communications and monitoring the status of weaponry.The officials noted that the effort is limited to whatever the aircraft can gather by staying in international airspace.Several US military officials continue to emphasize there are no military options actively being considered for the Venezuela crisis. For now, the US military would only contemplate a response if US assets, personnel or the embassy were attacked.Venezuela is in crisis as self-proclaimed interim president Juan Guaido battles Maduro for control.Guaido has called for other nations to send aid to the country in response to worsening food and medicine shortages. Maduro denies a humanitarian crisis exists in Venezuela and says the aid efforts are part of a coup attempt.Over the weekend, violence broke out when the Venezuelan military blocked aid convoys at the country's border.In the state of Tachira, along the border with Colombia, more than 300 people were hurt in clashes that involved firearms and Molotov cocktails, said the Venezuelan government's special envoy for Tachira state, Freddy Bernal.He said the attacks were conducted by irregular groups protesting Maduro's government on the international bridges along the border between Venezuela and Colombia -- the Simon Bolivar bridge in San Antonio and the Francisco de Paula Santander bridge in Ure?a."We registered no deaths despite the violent attacks for more than 15 hours of battle" by groups on the international bridges fighting "against thousands of patriots who fought and defended themselves," he said. CNN has not independently verified the numbers of the injured in these clashes.The opposition group said five people were killed. CNN has not verified those numbers.In other developments:?

The Senate has overwhelmingly approved a new North American trade pact that rewrites the rules of trade with Canada and Mexico. Passage of the measure gives President Donald Trump a major policy victory before senators turns their full attention to his impeachment trial. The measure goes to Trump for his signature. It would replace the 25-year-old North American Free Trade Agreement, known as NAFTA. It tore down most trade barriers and triggered a surge in trade. But Trump and other critics blamed NAFTA for encouraging U.S. companies to move their manufacturing plants south of the border to take advantage of low-wage Mexican laborers. 654
